Subject: [PATCH 01/37] test(render): give each serve fixture a distinct port

Port discovery releases the socket before the child binds it, so parallel fixtures could reach each other's server. Keep issued ports distinct and report a child that exits before it becomes healthy. Retry on a fresh port, at most three times, when the server's bind is refused.

Subject: [PATCH 02/37] build: pull pinned prerequisite images from
 digest-identical mirrors

CI services, release recipe roots, and the bregctl, caseworkctl, and messagingctl dev databases pull PostgreSQL, Debian, and Mailpit from the ECR Public Docker Official Images and GHCR mirrors at the same manifest digests. Public help keeps the canonical identities, and retained dev containers accept either exact reference.

From 9b7f360663584a0a4e9332d61e27306c021dc6fb Mon Sep 17 00:00:00 2001
From: Jeremi Joslin <jeremi@joslin.fr>

Subject: [PATCH 03/37] refactor(platform,breg): share the exact task-grant
 status transport

Move the task-grant status registry and the exact-status request into registry-platform-oidc, and define the taskGrantStatus entry once as the TaskGrantStatusConfig shared block in registry-platform-config, so every resource server checks a grant through one bounded transport configured by one block. BReg keeps its persisted binding and BReg-only bounds validation and now calls the shared transport. registry-platform-httputil exposes the private_key_jwt identity check and requested-scope validation the transport needs.

+## Fresh task authorization status
+
+`task_grant::TaskGrantStatusBinding::from_verified` captures the original
+verified grant principal, client, resource, purpose, bounds, disclosed identity
+subjects, and deadline. Products first enforce their own supported bounds and
+claim profile. A product may retain its own persisted binding and refuse bounds
+it does not support before delegating to the shared transport.
+
+`TaskGrantStatusEndpoint` names one authority: its issuer, the base URL and the
+status path appended to it, which holds exactly one whole `{grantId}` segment,
+the token endpoint and client credentials, and the one resource and one scope
+the service credential is requested for. A runtime's `taskGrantStatus` entries
+carry these values in the shared `TaskGrantStatusConfig` block of
+`registry-platform-config`, which owns their grammar and defaults (Casework's
+status route and scope) and maps onto `TaskGrantStatusEndpoint` with `From`.
+
+`TaskGrantStatusRegistry` pins each authority to its endpoint and the resource
+server's own private-key-JWT service credential. Each `check` obtains a fresh
+strict status document and compares every immutable member. Only the service
+credential is cached; a positive authorization observation never is. Unknown
+sources, inactive/mismatched contexts, and expired grants are refused. Outages
+are unavailable. A status endpoint rejecting the resource server's service
+credential with HTTP 401 or 403 also makes the observation unavailable; it does
+not establish that the task grant is inactive. Concealed or missing grants
+(HTTP 404) remain refused. The complete observation, including service token
+acquisition, is bounded to ten seconds, with a five-second status HTTP timeout and a 64 KiB
+response ceiling. Products decide when the check precedes their effects and
+how failures map to their own API; the primitive owns no mutation or durable
+lifecycle state.

Subject: [PATCH 04/37] feat(casework): approve deferred task grants for
 delayed work

A task template may opt into authorizationMode: deferred for an approved duration of at most seven days; omitted mode stays immediate with its 900-second ceiling. Deferred review grants pin a trigger-maintained assignment generation, so release, reassignment, or completion cannot revive an approval, and retained work-item grants reuse the existing invalidation triggers. The clients, bindings, facade, and OpenAPI carry the mode.

Refs #1952

 A keyed mutation whose outcome is unknown (a timeout or broken exchange after
 it was sent, an unusable answer, or a 5xx) is resent identically under the same
 key up to `maxMutationRetries` times: 0 to 2, default 2, and 0 sends it once.

+## Deferred bounded task authorization
+
+The stored grant now distinguishes an immediate window from explicit
+`authorizationMode: deferred`, with a selected duration no longer than seven
+days. Immediate defaults and serialized template bytes remain unchanged.
+Short assertions and execution tokens do not extend the original grant.
+
+The threat is delayed/restarted work needing repeated approval, or renewal
+reviving, widening, or extending authority. Core template validation and the
+PostgreSQL authorization-window constraints hold immediate grants to 900
+seconds and deferred grants to 604800 elapsed seconds, independent of database
+timezone and daylight saving changes. Casework checks the exact registered
+agent, active immutable template, approver eligibility, proposal identity and
+subject facts before assertion release, and checks again after source I/O.
+
+Retained work-item grants reuse the existing item and directory invalidation
+triggers. A release withdraws authority permanently in its task transaction,
+before any later reclaim, while a benign revision alone does not. Assignment
+owner and absence metadata alone are not legacy grant eligibility inputs; the
+existing contract continues to govern the current holder and template eligibility.
+
+Deferred review grants bind a monotonic assignment generation maintained by a
+task-row trigger. Responsibility changes increment it; draft revision changes
+do not. The trigger owns the generation value even on an update attempting to
+reset it. Approval captures the counter and rechecks it under the existing task
+lock. Release/reclaim or reassignment back cannot revive a grant without a new
+approval. A missing deferred counter fails closed. The first observed mismatch
+uses the existing transactional invalidation history and audit path.
+
+Review grant eligibility compares the request's current subject binding with
+the approved one for every grant, immediate grants included. The task revision
+an immediate grant pins covers the task row and not the request row, so a
+subject that differs from the approved one invalidates the grant with reason
+`eligibility` even when the task revision is unchanged
+(`immediate_review_task_grants_refuse_a_changed_request_subject`).
+
+Deferred grants cannot carry Evidence bounds (CASEWORK-SEC-27). Evidence checks
+the earlier token and grant deadline and no grant status, and its contract that
+an assertion stays usable after authority revocation only until the immutable
+grant deadline assumes the 900-second immediate window. Core template
+validation refuses `authorizationMode: deferred` with `bounds.type: evidence`
+as `casework.task-template.deferred-evidence`; `caseworkctl check`, package
+activation, and runtime project load all run it, and the generated project
+schema carries the same condition. The assertion signer also refuses a stored
+deferred Evidence grant, so no Evidence assertion is signed under the deferred
+window. `deferred_authorization_cannot_carry_evidence_bounds` and
+`task_assertion_refuses_a_deferred_evidence_grant` are the negative tests.
+
+The core mode/window boundary test and deferred HTTP regressions exercise
+restart with simulated elapsed authorization time, unrelated source revision
+changes,
+material proposal change, principal change, expiry, revocation, drafts,
+completion, responsibility transitions, and database timezone boundaries. The simulation ages only synthetic
+fixture timestamps; it does not assert a real sixteen-minute wall-clock wait.

+
+Retain the grant ID, original deadline, and the owning product's logical
+operation/idempotency key. After waiting or restarting, authenticate as the
+same agent and construct a fresh exchange provider using the original grant
+reference and deadline. An assertion refresh is neither a new authorization
+nor a new operation. Expiry or cancellation requires an explicit new decision;
+there is no fallback to standing service authority. Deferred work reaches BREG
+or Scheduling only: deferred grants cannot carry Evidence bounds, because
+Evidence accepts a grant until its deadline without checking its status.
+
+This mode retains the current holder's continuing authority. It does not
+survive release, reassignment, or completion of the review task. Keep that task
+active while the approved deferred work waits, then complete it when the
+workflow no longer needs the authorization. An institutional decision that
+survives task completion requires a separately designed policy.
+
+The grant limits allowed operations, resources, principal, purpose, subject
+facts, and deadline. It does not promise one business effect. Each resource
+server owns its atomic business limits and duplicate rules; preserve the same
+operation key across refresh and restart to recover the same effect. A new key
+names a new logical operation, still inside the approved bounds.
+
+Source proposal version, digest/integrity, binding generation, and exact
+subject facts are material. Unrelated source revision churn is not. Temporary
+source/status failure refuses the current attempt and can be retried; an
+observed definitive change invalidates permanently. Review directory eligibility
+is checked at observation, so removing and restoring a membership between
+observations is not a historical revocation signal. Use explicit revocation
+when authority must stay withdrawn.

Subject: [PATCH 05/37] feat(scheduling): check fresh task-grant status before
 capacity work

An optional taskGrantStatus registry makes Scheduling obtain a fresh exact status answer from the grant's Casework authority, through the shared platform transport, before every capacity commitment and idempotent replay, with no fallback once configured. Without it, only a grant with at most 900 seconds remaining is accepted. The capacity transaction rechecks the earlier token and grant deadline after lock waits. SCHEDULING-SEC-03 becomes enforced and the SCHEDULING-DEF-01 deferral is closed.

-The bounds themselves are not read again at that point, and Scheduling does not ask the issuer whether

-grant it mints to at most 900 seconds; Scheduling verifies a grant's deadline but does not cap it, so
-hold grants from any other authority to deadlines as short. Casework answers a grant's current status
-at `GET /v1/task-grants/{grantId}/status`, but asking it would put Casework's availability inside every

+The grant's bounds are matched at the service before the capacity transaction opens. When the runtime
+has any `taskGrantStatus` entry, Scheduling also obtains a fresh exact answer from the authority selected
+by the signed source issuer before every commitment and idempotent receipt replay. The authority must say
+the grant is active and reproduce its exact identity, bounds, signed subjects, and deadline. An inactive,
+mismatched, unlisted, or incompletely bound grant answers `operation.not-authorized`; an authority or service
+credential outage, including an unusable authority response, answers `service.unavailable`. Positive answers
+are not cached, and the complete attempt is limited to ten seconds. No capacity lock is held during the outbound call.
+This is a fresh observation rather than a distributed transaction: withdrawal after a positive answer can race
+the in-flight local commit.
+
+Inside the transaction, after lock waits and immediately before commit, Scheduling checks the earlier of
+the verified access-token and grant deadlines. A credential that expires after the status answer cannot
+take capacity through a delayed transaction. The earlier deadline bounds the status-to-commit race but does
+not make revocation atomic across products. An entirely unconfigured deployment accepts only the bounded
+offline path for grants with no more than 900 seconds remaining. Any configured entry disables that
+fallback for every source. Because the token does not name the original authorization mode, the final 15
+minutes of a deferred grant can use the offline path on an unconfigured deployment; deployments accepting
+deferred grants should configure status.

+```
+
+Offline runtime checks require at most 32 entries with distinct absolute
+`sourceIssuer` identifiers, safe service and token URLs, non-empty client and
+assertion audience, an absolute Casework resource, one status scope token, and
+a status path with one `{grantId}` segment. They validate secret
+reference structure without resolving the private key or CA bundle or contacting
+an endpoint. Activation repeats the structural check and verifies key and CA
+contents.
+
+`sourceIssuer` must exactly equal the source issuer in the signed task grant.
+`baseUrl` selects that authority's HTTPS API. `tokenEndpoint`,
+`clientAssertionAudience`, `clientId`, and `privateKeyRef` configure the
+private-key JWT client credential used to obtain a token for
+`caseworkResource` with the `statusScope` scope. The private key is a JWK
+whose `kid` selects its registered public key. `caBundleRef` is optional and
+applies a private CA bundle to both outbound HTTPS connections.
+
+`statusScope` and `statusPath` are optional. Omitted, Scheduling requests the
+`casework:grants:status` scope and calls Casework's
+`/v1/task-grants/{grantId}/status` route under `baseUrl`. Set them only for a
+task authority that answers under another scope or route: `statusScope` is one
+scope token, and `statusPath` starts with `/` and holds exactly one whole
+`{grantId}` segment.
+
+Once the list contains any entry, a fresh exact status answer is mandatory for
+every capacity commitment and idempotent receipt replay. The authority must
+return the signed grant's exact identity and bounds and say it is active. An
+inactive, mismatched, unlisted, or incompletely bound grant answers
+`operation.not-authorized`; an authority or credential outage, including an
+unusable authority response, answers `service.unavailable`. Positive answers are not cached. The full attempt is
+limited to ten seconds and completes before the capacity transaction opens, so
+no PostgreSQL capacity lock is held during the outbound call. Duplicate source
+issuers or invalid endpoints, credentials, or secret references refuse startup.
+The positive answer is an observation rather than a distributed transaction:
+a withdrawal after the answer can race the in-flight Scheduling commit.
+
+When the list is absent or empty, Scheduling accepts only the bounded offline
+path: the grant must have no more than 900 seconds remaining at request entry.
+Because the signed token does not identify whether its grant was originally
+immediate or deferred, the final 15 minutes of a deferred grant can use that
+path on an unconfigured deployment. Any configured entry disables the fallback
+for every source. After any status answer, the capacity transaction checks the
+earlier of the verified access token deadline and the grant deadline again
+after lock waits and immediately before commit. That earlier deadline bounds
+the status-to-commit race; it does not make revocation atomic across products.
+
 Scopes authorize reads only. Every commitment takes its authority from a task
 grant instead, which [TASK_GRANTS.md](TASK_GRANTS.md) documents.

-## Grant status stays out of the capacity transaction
-
-Casework answers a resource server's question about a task grant's
-current status at `GET /v1/task-grants/{grantId}/status`, and the Base
-Registry Engine (BReg) asks it before each task-granted write. Scheduling
-does not ask, and SCHEDULING-DEF-01 stays deferred with its reason
-restated. This is an authorization decision, so it is recorded here; the
-runtime and its tests are unchanged.
-
-**Threat.** A grant revoked at Casework, or invalidated there because its
-holder lost eligibility or its template retired, still commits capacity at
-Scheduling until its deadline passes: the token the agent already holds
-carries the bounds, and Scheduling never asks whether the grant is still
-active.
-
-**Decision.** Keep the deferral. A grant Casework mints lives at most 900
-seconds from its approval (`TASK_GRANT_LIFETIME_SECONDS` in
-`crates/registry-casework-core/src/task_grant.rs`, which every task
-template is held to), and Scheduling re-checks the grant's expiry inside
-the capacity transaction, after every lock wait and immediately before
-the claim commits (SCHEDULING-SEC-03). The exposure is therefore the rest
-of one short deadline. A status call would put Casework's availability
-inside every capacity transaction: each commitment would hold its
-capacity locks while it waits on another product, and would have to
-refuse while that product is unreachable, because answering without the
-status would make the check decorative. BReg accepts that cost for most
-of its writes: it asks inside the write's transaction, waits at most five
-seconds, and refuses the write when no answer arrives in that time. For a
-change-request apply and an Evidence-guarded action it asks before the
-transaction opens and re-checks only the grant's expiry inside it, which
-keeps the locks free but leaves the window between the answer and the
-commit, so that shape narrows the exposure without closing it.
-
-**Revisit trigger.** An adopter needs a revocation to take effect faster
-than a grant expires. Closing the deferral then adds a Scheduling adapter
-over `registry-casework-client`, which relaxes the MVP dependency sentence
-in `AGENTS.md` and `products/scheduling/scripts/check_dependency_direction.py`
-in the same change, and promotes SCHEDULING-DEF-01 to an enforced row with
-the negative test that earns it.
-
-**Tests.** None change. `a_grant_that_lapses_before_the_commit_never_books`
-and `every_mutation_rechecks_expiry_after_its_writes` (SCHEDULING-SEC-03,
-`crates/registry-scheduling/tests/postgres_commitments.rs`) remain the
-proof that the compensating expiry re-check holds.
-
-**Accepted residual.** The 900-second ceiling is Casework's, not
-Scheduling's. Scheduling verifies a grant's deadline but does not cap how
-far ahead it lies, and its token verifier sets no maximum token lifetime,
-so a deployment that accepts grants minted by another authority takes
-that authority's grant lifetime as its revocation window. Holding that
-authority to deadlines no longer than Casework's is the deployment's
-responsibility; Scheduling does not enforce it.
+## Fresh task-grant status stays outside the capacity transaction
+
+Casework answers a resource server's question about a task grant's current
+status at `GET /v1/task-grants/{grantId}/status`. Scheduling now uses the
+shared platform status transport before each capacity commitment and each
+idempotent receipt replay when `taskGrantStatus` is configured. This keeps
+Scheduling independent of Casework's implementation crate while sharing the
+same exact wire contract with BReg.
+
+**Threat.** A grant revoked at Casework, invalidated by a holder reassignment,
+or changed at the authority could otherwise keep committing capacity through
+an already issued access token. A request could also receive an active status
+answer and then wait on a capacity lock until its short execution credential
+expired.
+
+**Decision.** The authority must answer with `active: true` and reproduce the
+exact grant id, source issuer, principal, client, resource, purpose, bounds,
+signed subject values, and deadline. A mismatch, inactive response, incomplete
+signed binding, or unlisted source is an authorization refusal. An authority
+or service credential outage, including a malformed authority response, is a
+service outage. Positive answers are never cached, and the complete attempt,
+including acquisition of the service credential, has a ten-second limit.
+
+The status call completes before the capacity transaction opens, so it holds no
+capacity lock while waiting on another product. The transaction then checks
+the earlier of the verified access-token and grant deadlines after every lock
+wait and immediately before commit. This bounds the interval between status
+and commit by the short execution credential, even when the grant remains live
+for days. It does not create a distributed transaction: a withdrawal after a
+positive status answer can still race the in-flight local commit.
+
+An entirely unconfigured runtime accepts the bounded offline path only when the
+grant has no more than 900 seconds remaining at request entry. Any configured
+status entry disables that fallback for all grants, including sources that are
+not listed. New deployments that accept deferred grants must configure status.
+
+**Tests.** `configured_task_status_is_fresh_for_a_capacity_commit_and_its_replay`
+proves that an initial capacity claim and its duplicate operation each obtain
+a fresh status while the ledger records one effect.
+`inactive_mismatched_and_unavailable_task_status_commit_no_capacity` covers
+closed refusals and authority outage.
+`unconfigured_status_accepts_at_most_fifteen_minutes_of_remaining_lifetime`
+pins the 900-second offline path at both sides of its bound, and
+`a_commitment_blocked_past_its_access_token_deadline_never_books` holds a real
+PostgreSQL capacity lock until the execution credential has expired. All are in
+`crates/registry-scheduling/tests/postgres_commitments.rs` and carry
+SCHEDULING-SEC-03.
+
+**Accepted residual.** The signed token does not identify whether Casework
+issued the grant in immediate or deferred mode. On a deployment with no status
+configuration, the final 15 minutes of an originally deferred grant therefore
+qualify for the bounded offline path. Operators who accept deferred grants close
+that residual by configuring at least one status authority, which makes status
+mandatory for every source.

-      The grant's bounds travel in the presented token and are matched once at

-      inside the capacity transaction (SCHEDULING-SEC-03). Re-reading the
-      bounds there only defends against a grant revoked or narrowed at the
-      issuer between the door and the commit. Casework answers that question at
-      GET /v1/task-grants/{grantId}/status, and the Base Registry Engine (BReg)
-      asks it before each task-granted write, but a status call from Scheduling
-      would put Casework's availability inside every capacity transaction: each
-      commitment would hold its capacity locks while it waits on another
-      product, and would have to refuse while that product is unreachable.
-      Revisit when an adopter needs a revocation to take effect faster than a
-      grant expires.
-    compensatingControl: >-
-      Casework, the maintained grant issuer, holds every task grant to a
-      lifetime of at most 900 seconds, and the expiry re-check inside the
-      transaction means a revoked grant commits capacity for at most the rest
-      of that deadline. Scheduling verifies a grant's deadline but does not cap
-      it, so a grant minted by another authority keeps that authority's
-      lifetime. The published reference states the limit and the revisit
-      trigger plainly rather than claiming the bounds are re-read.

Subject: [PATCH 06/37] feat(scheduling,messaging): read original receipts
 without replaying commands

A caller recovering from a lost response can now observe the retained
original receipt for its own key and exact request without submitting the
command again: Scheduling serves POST /v1/appointments/receipt under
ordinary read authentication, and Messaging serves POST
/v1/messages/receipt. Lookup stays scoped to the caller's verified
identity, and neither route renders, submits, or claims capacity.

The Rust clients, the Node.js and Python bindings, the unified facades,
the generated OpenAPI documents, the API reference pages, and the security
contracts carry the new routes.

+under current ordinary read authority. It returns `200` with the retained
+original success receipt for the same verified issuer and configured principal. It never
+repeats the business operation. A same-principal read credential can observe

+that principal. `409 receipt.unresolved` covers unavailable evidence such as
+a missing, expired, or changed receipt and does not prove that no effect occurred.

+## Original receipt observation
+
+Threat: recovery submits a second effect after cancellation, expiry, or restore,
+or accepts a different caller's receipt as evidence of its original command.
+The receipt lookup uses current ordinary read authority, the original verified
+issuer and configured principal, the exact operation key, and the existing canonical request
+hash. It reads only retained successful receipts and never renders, writes business state,
+replays, or creates an attempt. Task lineage already stored with the original
+operation is preserved. A different standing identity gains no ownership.
+
+Missing, changed, erased, expired, and non-success receipts all answer the
+value-free `409 receipt.unresolved`. That response establishes no absence of
+effect. A durable audit request precedes the database lookup and its response
+precedes disclosure of the receipt. Payloads, keys, and raw identities never
+enter these audit records. The focused PostgreSQL receipt tests exercise
+ownership, exact-request refusal, retention, and unchanged product state.
+
+Receipt observation uses no submission rate budget because it neither renders
+nor sends. Exhausting that budget must not prevent recovery of an already
+accepted command. Authentication, bounded bodies, exact caller/request matching,
+retention, and audit gates still apply. The PostgreSQL test
+`original_receipt_reads_neither_spend_nor_require_submission_budget` reads the
+same stored receipt before and after the budget is exhausted and proves that
+the next submission is still rate limited.

+under current ordinary read authority. It returns `200` with the retained
+original success receipt for the same verified issuer and subject. It never
+repeats the business operation. A same-principal read credential can observe

+that principal. `409 receipt.unresolved` covers unavailable evidence such as
+a missing, expired, or changed receipt and does not prove that no effect occurred.
+The receipt route authenticates before checking the JSON media type and decoding
+its bounded body. The router still rejects a declared body larger than one MiB
+before entering the handler. Authenticated callers retain the usual malformed
+JSON, unsupported media type, request-shape and body-size refusals.

+replays, or creates an attempt. Task lineage already stored with the original
+operation is preserved. A different standing identity gains no ownership.

+Missing, changed, erased, expired, and non-success receipts all answer the
+value-free `409 receipt.unresolved`. That response establishes no absence of
+effect. A durable audit request precedes the database lookup and its response
+precedes disclosure of the receipt. Payloads, keys, and raw identities never
+enter these audit records. The focused PostgreSQL receipt tests exercise
+ownership, exact-request refusal, retention, and unchanged product state.

From a0b6ba7cd450baa3b9ca54fc172c7d51a842a3d6 Mon Sep 17 00:00:00 2001
From: Jeremi Joslin <jeremi@joslin.fr>

Subject: [PATCH 07/37] feat(breg,casework): wire local task-grant status and
 resource grants in dev sessions

bregctl dev derives the generated runtime's principal claim from the
compiled access profiles, resolves a `$localClientSubject` fixture marker
for `sub` journeys, and binds declared Casework task-grant status services
with their own status-only clients. Authored machine-client `grants` give
a local client exact registered scopes on other resources through the
ThunderID tooling's explicit `ordinary_resource_permissions` allowlist,
which stays empty, and bootstrap-only, by default.

caseworkctl dev refuses borrowed sessions whose access profiles use `sub`
and reports known integration and shared-registration mismatches with a
fixed diagnostic category and the clients-file section to correct.

Subject: [PATCH 08/37] docs(release): record the task-grant seams in the
 product changelogs

Adopters upgrading need the deferred grants, the shared status transport,
the Scheduling offline bound, the receipt routes, the stricter BReg status
configuration, and the changed client and caseworkctl refusals in one
place, with a migration for each breaking change.

+- BREAKING: the task-grant status check before a governed write, a later
+  approval, or an application reports a 401 or 403 from the Casework status
+  endpoint as an outage, so the request answers `service.unavailable` (503)
+  where it answered `precondition.failed` (412): such an answer refuses the
+  engine's own status credential, not the grant. A 404 still refuses the
+  grant with `precondition.failed`. The check runs through the shared
+  platform transport, which identifies itself with the user agent
+  `registry-task-status` (was `registry-breg-task-status`) and bounds the
+  whole attempt at ten seconds; the engine's own five-second bound on the
+  check still ends it first. Migration: alert on `service.unavailable` for a
+  misconfigured or revoked status client, and match the new user agent in
+  Casework access logs.
+- BREAKING: the runtime checks each `taskGrantStatus` entry when it reads
+  the file, and refuses an invalid one as
+  `breg.runtime.invalid-task-grant-status` at `/taskGrantStatus`, where only
+  activation refused it, as `breg.runtime.invalid-binding`. The members are

+  control characters), and `caseworkResource` is an absolute resource URI.
+  `sourceIssuer` accepts an absolute URN issuer as well as a URL, since it
+  is compared and never fetched. Migration: none for an entry the runtime
+  already activated; a script that matched `breg.runtime.invalid-binding`
+  for a malformed entry matches the new code.
+- A `taskGrantStatus` entry takes the optional members `statusScope` and
+  `statusPath`. Omitted, the engine requests the `casework:grants:status`
+  scope and calls `/v1/task-grants/{grantId}/status` under `baseUrl`, as
+  before. Set them only for a task authority that answers under another
+  scope or route: `statusScope` is one scope token, and `statusPath` starts
+  with `/` and holds exactly one whole `{grantId}` segment.
+- BREAKING: `bregctl dev` derives the generated runtime's principal claim
+  from the compiled access profiles, where it always mapped
+  `registry_principal`, and refuses a project whose authenticated profiles
+  use different claims. A `sub` project uses the issuer's subject. A native
+  fixture journey under a `sub` profile writes
+  `claims: {principal: "$localClientSubject"}`, which resolves to the
+  selected local client's registered subject in the private captured
+  project only. Migration: give every authenticated profile the same
+  principal claim.
+- `bregctl dev` binds the Casework task-grant status services a
+  `dev-clients.yaml` declares under `taskGrantStatus`, at most eight, each
+  with its own status-only client on a numeric loopback endpoint, into the
+  generated runtime. A machine client may declare `grants`, at most seven
+  audiences each with 1 to 32 scopes that resource declares, to request
+  ordinary tokens at other issuer resources; the grants change neither its
+  primary scopes, its exported resource, nor its BReg admission. See
+  `products/breg/DEV.md`.

 ## Unreleased
 
+- Task templates may opt into `authorizationMode: deferred` for delayed
+  work, with a `lifetimeSeconds` of at most 604800 (seven days). An omitted
+  mode stays `immediate`, with its 900-second ceiling. The preview, the
+  grant view, the Rust client (`TaskAuthorizationMode`), and the Node.js and
+  Python clients (`authorizationMode`) carry the mode, which they omit for an
+  immediate grant; approval still names only the template id and version. A
+  deferred review grant pins the task's assignment generation, so a release,
+  reassignment, queue move, absence-cover change, decision, or completion
+  ends it and a later reclaim does not revive it; a draft revision does not.
+  Deferred grants cannot carry Evidence bounds: `caseworkctl check` reports a
+  deferred template with bounds of type `evidence` as
+  `casework.task-template.deferred-evidence`, the project schema refuses it,
+  and the task authority signs no assertion for such a grant. A deferred
+  grant reaches the Base Registry Engine, which checks fresh grant status
+  before it writes, or a Scheduling deployment that configures
+  `taskGrantStatus`. See `products/casework/TASK_GRANTS.md`.
+- Migration 0022 replaces the check constraints `casework_task_grants_check`
+  and `casework_review_task_grants_check` with
+  `casework_task_grants_authorization_window` and
+  `casework_review_task_grants_authorization_window`, which bound a grant's
+  expiry by its template's mode: 900 seconds immediate, 604800 seconds
+  deferred. It adds `casework_review_tasks.assignment_generation` and the
+  `BEFORE UPDATE` trigger `casework_review_assignment_generation`, which
+  increments it when the state, queue, holder, assignment owner, assignment
+  kind, or absence ids of a review task change. The migration scans the
+  three tables under an exclusive lock to validate the constraints and
+  rewrites none of them. The trigger then runs on every update of a review
+  task, draft revisions included: it writes no extra row version and adds
+  eight bytes to each row.
+- BREAKING: `caseworkctl dev` reports five configuration refusals by their
+  own codes and exits with status 1, where it reported each as
+  `caseworkctl.operational-failure` and exited with status 3:
+  `caseworkctl.dev.integrations-invalid` at
+  `dev-clients.yaml:/integrations`, `caseworkctl.dev.shared-client-mismatch`
+  at `dev-clients.yaml:/clients`,
+  `caseworkctl.dev.shared-task-authority-mismatch` at
+  `dev-clients.yaml:/integrations/taskAuthority`,
+  `caseworkctl.dev.source-binding-invalid` at
+  `dev-clients.yaml:/integrations/sources`, and
+  `caseworkctl.dev.borrowed-principal-invalid` at
+  `casework.yaml:/accessProfiles/principalClaim`. Each suggests the
+  correction and keeps the underlying cause out of the report. Migration: a
+  script that read exit status 3 for these refusals reads status 1 and the
+  code.
+- BREAKING: `caseworkctl dev` refuses a session that borrows another
+  project's issuer when a Casework access profile uses `principalClaim: sub`,
+  as `caseworkctl.dev.borrowed-principal-invalid`: in a borrowed session
+  `sub` names the issuer owner's subject, not the Casework principal.
+  Migration: use a stable claim such as `registry_principal` in every access
+  profile and register it for each client in both projects'
+  `dev-clients.yaml`.
+- BREAKING: `CaseworkTaskAssertionSource` in the Rust client, which
+  `registry-stack-client` re-exports, reports a Casework 4xx answer to an
+  assertion request other than 408 and 429 as an invalid credential
+  (`TokenError::Invalid`, kind `invalid-credential`) with fixed text, where
+  it reported every failure as `unavailable`. An expired, revoked, or absent
+  grant is such a refusal, even when its problem body is malformed. A 408,
+  429, or 5xx answer stays `unavailable`, a transport failure keeps its
+  transport kind, and the source still sends the assertion request once.
+  Migration: treat `invalid-credential` as a refusal that needs a new
+  approval, and stop retrying it.

+  `TaskGrantStatusEndpoint`, `TaskGrantStatusRegistry` (with an offline
+  `validate_configuration`, `activate`, and `check`),

+  A check obtains a private-key JWT credential for one status scope, calls

 ## Unreleased
 
+- The runtime file takes an optional top-level `taskGrantStatus` list of at
+  most 32 Casework task authorities, each named by the exact `sourceIssuer`
+  its grants carry. Once the list holds an entry, every capacity commitment
+  and idempotent replay first obtains a fresh exact status answer from the
+  grant's authority, with no fallback: an inactive, mismatched, unlisted, or
+  incompletely bound grant answers `operation.not-authorized`, and an
+  authority or credential outage answers `service.unavailable`. The whole
+  check is bounded at ten seconds and ends before the capacity transaction
+  opens. `statusScope` and `statusPath` are optional and default to
+  Casework's `casework:grants:status` scope and
+  `/v1/task-grants/{grantId}/status` route. See
+  `products/scheduling/RUNTIME-CONFIG.md`.
+- BREAKING: a deployment with no `taskGrantStatus` entry accepts a task
+  grant only while it has at most 900 seconds left at request entry; a grant
+  with more answers `operation.not-authorized` (403) and is audited as
+  refused, where every unexpired grant was accepted. A Casework immediate
+  grant never lasts longer, so the refusal meets only a deferred grant or a
+  longer grant from another authority. After it acquires its locks, the
+  capacity transaction now rechecks the execution token's expiry as well as
+  the grant's. Migration: configure `taskGrantStatus` for every task
+  authority whose grants outlive fifteen minutes.
+- `POST /v1/appointments/receipt` returns the retained original success

Subject: [PATCH 09/37] feat(platform): add sealed values, binary secrets, and
 replay hooks

Shared primitives a durable workflow runtime needs and no current product
reaches yet:

- platform-config resolves binary key files through
  `resolve_binary_reference`; `resolve_reference` still refuses NUL bytes
  for textual secrets.
- platform-crypto adds `sealed_value`: bounded AES-256-GCM values with
  HKDF-SHA256 domain separation and caller-supplied context, reusing the
  field-encryption envelope mechanism without changing BReg's field
  contract.
- platform-dispatch adds a `write_replay` store hook inside the replay
  transaction and exposes the core job-shape predicate to a product that
  creates its own job table.
- platform-testing signs fixture tokens with a supplied issuer key and its
  algorithm, not only the Ed25519 fixture key.
- platform-yaml carries an explicitly foreign JSON subtree as
  `ForeignValue`.
- The configuration-conventions lint accepts `target: none` for a generated
  build artifact without an exception class.
- The configuration conformance check lets a `RustBlock` row marked
  `repeated` require a `Vec` of one shared block, such as one pinned
  package per flow, and refuses any other element type.

Coordinator publishes operation input and output schemas derived from the
exact documents its Scheduling adapter reads and writes. The derives sit
behind the existing schema feature and leave every serde attribute as it is;
the committed Scheduling schemas and OpenAPI document are unchanged.

Subject: [PATCH 15/37] feat(coordinator): add the Registry Coordinator runtime
 and authoring tooling

Registry Coordinator runs a reviewed, finite sequence of Registry Stack
calls across durable waits, service outages and worker restarts. One
optional Rust service executes acyclic YAML workflows with declarative
mappings and bounded pure Rhai functions, keeps encrypted progress and
prepared commands in its own PostgreSQL database, and leaves the
authorization and ownership of every external effect with the product
that receives the call.

A workflow reads records, waits until an instant, chooses a branch, calls
an operation from a closed, versioned catalog and finishes with a
declared outcome. Each catalog operation publishes its input and output
contracts: check fits every reference, literal and fields mapping to the
schemas it reads and feeds, and the runtime refuses a call input outside
its contract before dispatch. Calls reach BReg, Messaging and Scheduling
through their maintained clients, plus a configured external read and a
decision evaluation. Mutations keep their prepared command and original
key, retry within the run deadline and honour Retry-After, and recover
against the receiving product's original-key receipt where it has one.

A deployment serves several flows, one pinned package each, as one trust
domain. Runs start only from an authenticated caller request, belong to
that caller, and can be listed, inspected, reconciled, retried or
cancelled under access policies; operator policies act deployment-wide.
The service shares a fixed pool of PostgreSQL sessions, counts runs,
attempts and refusals on a private metrics listener, and finishes the
attempt in flight before it stops.

coordinatorctl initializes projects with passing scenarios, checks and
explains them, tests their editor-checked scenarios, packages them, plans
and applies deployments, and operates runs, naming the fix for every
refusal without echoing values.

- crates/registry-coordinator: the coordinator service and coordinatorctl.
- products/coordinator: product contract, deployment runbook and
  checklist, example projects, generated schemas, OpenAPI and operation
  contracts, and contributor check and test scripts.
- Workspace, CI change detection, release source model, identifiers
  catalog, editor schema mappings, CLI catalog, configuration formats and
  docs site wiring.

+# Registry Coordinator
+
+Registry Coordinator executes reviewed finite, acyclic workflow packages using
+PostgreSQL, bounded pure Rhai functions and maintained Registry Stack clients.
+It serves authenticated institutional admissions, caller-owned progress and
+explicit operator recovery. Receiving products retain ownership and authority
+for every external effect.
+
+`coordinatorctl` checks and tests projects offline, builds immutable packages,
+applies PostgreSQL activation and operates the authenticated API. `coordinator`
+serves the activated packages and runs the worker without migrating at startup.
+
+See the [product contract](../../products/coordinator/PRODUCT-CONTRACT.md),
+[deployment runbook](../../products/coordinator/DEPLOYMENT.md), and
+[maintained projects](../../products/coordinator/README.md).

+//! Operational counters, served only on the operator-private metrics
+//! listener.
+//!
+//! `/metrics` is a route on a separate socket that `deployment.metricsListener`
+//! names, never on the public listener, so the public contract is unchanged
+//! and reaching the counters requires reaching a different, private address.
+//! Without `metricsListener` nothing is served.
+//!
+//! Every label is closed by construction: each one is an enum here, and every
+//! value is exposed from zero. Run identifiers, idempotency keys, inputs, step
+//! outputs, principals, clients, flow ids, step names, authored outcomes and
+//! problem details never become labels, so no caller can write text into a
+//! series and the series count is fixed by this file.
+//!
+//! The flow id is not a label either, although an operator declares it and a
+//! deployment serves at most sixteen. A per-flow series would need the run's
+//! flow at every count, which an attempt whose snapshot does not decode does
+//! not have, and it would make the series set depend on the deployment rather
+//! than on this file. The audit journal and `coordinatorctl` already answer
+//! per-flow questions.
+//!
+//! A run is counted as admitted when its admission commits; a replayed start
+//! key returns the original run and is not counted again. A run is counted as
+//! finished each time a committed transaction moves it into a terminal state,
+//! by that state, so a failed run an operator later retries or cancels counts
+//! again when it ends again. Step attempts are counted by what the worker's
+//! attempt came to, local steps (wait, choose, finish) included.
+//!
+//! Authentication refusals are counted here rather than written to the audit
+//! journal: a refused credential names no principal to hold accountable, and
+//! journaling it would let an unauthenticated caller grow the journal.
+//!
+//! The dispatch queue is a gauge sampled from the store when the metrics are
+//! scraped, counting only the states work waits in: `pending`, `leased`, and
+//! `unknown`. When the store cannot be read the gauge has no samples for that
+//! scrape, so the series goes stale rather than reporting an empty queue.
+//!
+//! Every counter is per process and starts from zero at each start; work done
+//! by `coordinatorctl` is a separate process and is recorded in the journal,
+//! not here.

+title: Registry Coordinator configuration reference
+description: Project, runtime, and offline scenario files for Registry Coordinator, with check commands and refusal recovery.
+status: draft
+owner: registry-docs
+source_repos:
+  - registry-stack
+last_reviewed: unreviewed
+doc_type: reference
+locale: en
+standards_referenced:
+  - json-schema
+---
+
+import ConfigurationFormatChecks from '../../../components/ConfigurationFormatChecks.astro';
+
+Check your Registry Coordinator project and deployment bindings before packaging a workflow.
+The three file formats use the shared [configuration conventions](../configuration-files/).
+Each product that receives a Registry Coordinator call retains authorization and ownership
+of its effects.
+
+{/* Evidence: products/platform/config-formats.yaml;
+    products/coordinator/PRODUCT-CONTRACT.md;
+    crates/registry-coordinator/src/project_check.rs. */}
+
+## Files and boundaries
+
+`workflow.yaml` carries `CoordinatorProject`, with execution bounds, logical connections, and
+finite steps. Its `project` block names the workflow and version. `functionsFile` names `functions.rhai`,
+which supplies bounded pure functions. Project checks validate the graph, function exports,
+references, and input and outcome schemas, and fit every mapping to the schemas it reads and feeds.
+
+`runtime.yaml` carries `CoordinatorRuntimeConfig`. It binds logical connections to product
+endpoints and authority, and declares deployment identities, state keys, audit custody, and
+secret providers. `deployment.packages` lists one pinned package per flow, up to sixteen; each
+entry names the package `root` and its `expectedDigest`, and the flow is the package's workflow ID.
+An offline check validates the configuration without resolving secret material,
+connecting to PostgreSQL, or contacting products.
+
+`scenarios.yaml` carries `CoordinatorScenarios`. Each case names its `id`, workflow input, typed
+fake replies, and expected execution result. `coordinatorctl test` replays these cases with a
+virtual clock; passing scenarios do not prove a live deployment or provider delivery.
+
+JSON Schema fragments and scenario payloads are foreign JSON trees: they can contain null values.
+Ordinary optional configuration members are omitted rather than written as null.
+
+YAML declares the finite graph, calls, durable waits and the references that carry values between steps.
+Use pure Rhai for logic: choosing among those authored branches, building nested requests or computing instants.
+Functions cannot acquire credentials, contact services or add steps to the graph.
+
+{/* Evidence: crates/registry-coordinator/src/authoring.rs, CoordinatorProject;
+    crates/registry-coordinator/src/runtime.rs, RuntimeConfig;
+    crates/registry-coordinator/src/scenarios.rs, CoordinatorScenarios;
+    crates/registry-coordinator/src/project_check.rs;
+    crates/registry-platform-yaml/src/types.rs, ForeignValue. */}
+
+## Mappings
+
+A mapping carries values into a step.
+A reference names one value: `{type: input}` reads the workflow input, `{type: step, step: read-application}` reads that earlier call's output, and `{type: literal, value: applications}` supplies an authored JSON value.
+An input or step reference may add an RFC 6901 `path`, such as `/data/recordIdentifier`, to select one member.
+A step reference must name a call that completed on every route into the reading step.
+Every mapping names its form with `type`: `fields`, `function`, or one of the reference types.
+
+| Member | Accepts |
+| --- | --- |
+| Call `input` | `type: fields`, an object of up to 64 named references, or `type: function` with up to 16 reference `arguments` |
+| Finish `output` | `type: fields`, an object of up to 64 named references, or `type: function` with up to 16 reference `arguments` |
+| `waitUntil` | One reference, or `type: function` returning an RFC 3339 instant |
+| `choose` | One reference, or `type: function` returning a case label |
+
+This call reads an application record without a function:
+
+```yaml
+read-application:
+  type: call
+  connection: applications
+  operation: read-record
+  input:
+    type: fields
+    fields:
+      collection: {type: literal, value: applications}
+      recordId: {type: input, path: /applicationId}
+  next: permission
+```
+
+Keep functions for logic: choosing a label from a record, building a nested request, or computing an instant.
+Functions read no clock.
+`add_seconds(instant, seconds)` returns an RFC 3339 instant moved by a signed number of seconds, written in UTC.
+`seconds_between(first, second)` returns the whole seconds from the first instant to the second, truncated toward zero.
+An instant without an offset, or a result outside the years 0000 to 9999, fails the function with `function.execution`.
+
+A `wait-until` step holds the run in PostgreSQL until its instant; an instant that has already passed continues at once.
+A wait that wakes at or after the run deadline ends the run `expired` with failure code `deadline-reached`.
+The graph has no cycles, so a run that checks a source repeatedly declares a fixed number of wait, read and choose rounds.
+The maintained [bounded poll project](https://github.com/registrystack/registry-stack/tree/main/products/coordinator/examples/bounded-poll) reads a record at three fixed times and then returns control to the caller.
+
+`coordinatorctl check` fits every mapping to the schemas it reads and feeds before any run:
+
+- A path must name a member that the workflow input schema or the called operation's output contract declares. Any path beneath an open member is accepted.
+- A `fields` mapping must set every member that its operation input or outcome requires, and no member it does not declare.
+- A literal must satisfy its member's schema. A reference cannot read a value declared with another type or string format.
+- A `waitUntil` reference must read a date-time or plain string.
+- A `choose` reference must read a string. When its schema lists the values, the cases must match them exactly.
+
+Each refusal names the step, the field path, what was expected, and the fix, one mapping at a time in step order.
+The published project schema also holds each `fields` mapping to its operation's member names in your editor.
+
+A function result, or a value read beneath an open member, is known only when the run computes it.
+`coordinatorctl test` holds every computed call input to its operation input contract, and every synthetic success reply to its operation output contract.
+The service checks every computed call input against its operation input contract before preparing, saving or sending the call.
+An input outside the contract fails the run with `invalid-command`.
+The run and step status report the RFC 6901 path into the input as `failurePath`, never the value.

+## Supported operations
+
+| Operation | Connection type | Effect | Recovery |
+| --- | --- | --- | --- |
+| `read-record` | `breg` | Read | Read again |
+| `submit-message` | `messaging` | Mutation | Same command and read-only receipt |
+| `read-scheduling` | `scheduling` | Read | Read again |
+| `read-availability` | `scheduling` | Read | Read again |
+| `create-appointment` | `scheduling` | Mutation | Same command and read-only receipt |

+| `external-get` | `external-http` | Read | Read again |
+| `evaluate-decision` | `decision` | Evaluation | Hold after uncertain dispatch |
+
+These eight identifiers are the complete inventory.
+There is no arbitrary HTTP method, SQL step or dynamic call destination.
+
+`invoke-breg-action` accepts `action` and an object-valued `input`.
+Its BReg runtime connection requires a standing service `authorization` and an explicitly permitted `profile` for the immediate action.
+It accepts no grant field and cannot use `authorization.taskAuthority`.
+The maintained Base Registry Engine (BReg) client validates metadata and prepares the conditional request without mutation.
+Coordinator saves the exact preparation and key before dispatch.
+Later attempts check current metadata and fresh authority while retaining the saved conditions and key.
+Changed contracts, stale conditions, denied authority, cancellation, recovery holds and the original deadline stop unsafe dispatch.
+An uncertain result remains unresolved by `reconcile`, because BReg has no read-only action receipt.
+An ordinary record read is not evidence that the original action succeeded.
+Task-bound operations retain their original approval deadlines across waits and retries.
+
+Execution snapshots pin the capabilities of each used operation.
+A changed digest needs a new workflow version when the same ID and version exists in retained history.

+
+## External HTTP reads
+
+Declare `external-http` as the project's logical connection type, then bind that name under `runtime.externalHttpConnections`.
+Product bindings remain under `runtime.connections`; the names across product, external HTTP, and decision maps must be distinct, with at most 16 connections in total.
+Omitting `externalHttpConnections` disables external reads.
+
+This runtime fragment permits one public directory path and one query parameter:
+
+```yaml
+externalHttpConnections:
+  directory:
+    baseUrl: https://directory.example.org/directory
+    paths: [offices]
+    queryParameters: [district]
+    responseSchema:
+      type: object
+      additionalProperties: false
+      required: [status, body]
+      properties:
+        status:
+          const: 200
+        body:
+          type: object
+```
+
+The call input is an object containing `path` and an optional `query` object of string values.
+Here, the mapped input could select `path: offices` and a `district` query value.
+It cannot supply a URL, method, headers or body.
+The service preserves the configured base path and issues GET with JSON acceptance.
+
+| Runtime member | Contract |
+| --- | --- |
+| `baseUrl` | Required absolute HTTPS URL, or numeric loopback HTTP; no credentials, query or fragment |
+| `paths` | Required 1 to 16 unique exact relative paths; no empty or dot segments, query, fragment or backslashes |
+| `queryParameters` | Optional 1 to 16 unique names; omission permits no query parameters |
+| `authorization` | Optional separately configured service identity; omission means a public read |
+| `responseSchema` | Required local JSON Schema for the complete `{status, body}` response; no external references or schema resource identifiers |
+| `attemptTimeoutMilliseconds` | 1 to 2000, default 2000; covers destination resolution, credentials and HTTP |
+| `maximumResponseBytes` | 1 to 65,536, default 65,536 |
+
+Each query value is at most 1024 bytes and cannot contain control characters.
+Authorization uses the ordinary service fields `tokenEndpoint`, `clientId`, `signingKeyRef`, `resource` and `scopes`.
+The optional `clientAssertionAudience` defaults to the token endpoint.
+It does not accept `taskAuthority`, inherit product authorization or forward the caller's credential.
+
+Redirects and prohibited destinations are refused.
+The adapter accepts an empty response body as null; a nonempty body must be valid JSON within the byte limit.
+The configured schema decides which HTTP statuses and body shapes are accepted, including any permitted non-success statuses.
+An invalid body or schema mismatch stops the read with `external-invalid-response`.
+A timeout or unavailable service is retryable as `external-unavailable` within the existing workflow deadline.
+Status 429 is retryable as `external-rate-limited`, and 502, 503 and 504 as `external-unavailable`, with a `Retry-After` in whole seconds as the floor for the next attempt.
+The last attempt delivers any of these statuses to the workflow under the configured schema, so the workflow sees one only after the retries run out.
+GET endpoints must implement read semantics; there is no external mutation or receipt recovery contract.
+
+The maintained [external directory project](https://github.com/registrystack/registry-stack/tree/main/products/coordinator/examples/external-directory) includes mappings and deterministic scenarios.
+Those scenarios and mock HTTP adapter checks do not prove a live institutional integration.
+

+
+## Typed decision models
+
+Declare a logical `decision` connection in your project and call `evaluate-decision`.
+Use `decisionConnections` in the runtime file to select a protocol and model.
+Omitting that map disables decision calls.
+The common contract supports predicates, choices, and ordered rubric scores.
+General structured generation, images, agent tools, and asynchronous jobs are not supported.
+
+```yaml
+decisionConnections:
+  assessor:
+    protocol: system-one
+    baseUrl: https://decision.example.org
+    model: institution-reviewed-model
+    authorization:
+      bearer:
+        tokenRef: secret:env/DECISION_TOKEN
+        principal: institutional-decision-account
+```
+
+`system-one` sends to `v1/systemone`; `openai-decisions` sends to `v1/decisions`.
+The configured base path is preserved.
+Use the service root as `baseUrl`, rather than repeating the protocol path.
+For an unauthenticated local service, explicitly use `authorization.local: {}` and a numeric loopback URL.
+The `principal` names the stable account represented by your bearer credential.
+Keep that account unchanged when rotating the secret; Coordinator cannot discover the account behind an opaque API key.
+
+`attemptTimeoutMilliseconds` accepts 1 to 8000, default 8000.
+`maximumRequestBytes` and `maximumResponseBytes` each accept 1 to 65,536, default 65,536.
+The time budget covers destination resolution, credentials, and HTTP.
+The client performs one request without redirects, ambient proxy use, or automatic provider fallback.
+
+Your input mapping supplies `state` and a `questions` object.
+State is a string, object, or array; object and array state becomes canonical JSON text for OpenAI.
+Question names and choice values are local identifiers.
+You can ask 1 to 32 named questions per call.
+Each question supplies text `instructions` and a `type`:
+
+- `predicate` asks for a probability from zero to one.
+- `choice` supplies `criteria` as a map from 2 to 32 allowed choices to their descriptions.
+- `score` supplies `criteria` as an ordered list of 2 to 10 rubric descriptions, indexed from zero.
+
+The result contains `protocol`, `requestedModel`, and named `answers`.
+`returnedModel` appears only when the provider supplies it; `usage` retains provider metadata.
+A predicate answer has `type: predicate` and `probability`.
+A choice answer has `type: choice`, `choice`, `probabilities`, and `nativeConfidence`.
+A score answer has `type: score`, `score`, `legend`, `probabilities`, and `nativeConfidence`.
+An OpenAI per-question refusal is `type: refusal`, with no numeric answer or copied provider explanation.
+System One HTTP refusals stop the call and do not become a typed review answer.
+Rubric scores can be fractional and are not probabilities.
+Native confidence preserves the provider's statistic; it is not normalized across models or a guarantee of correctness.
+
+Review which fields you send to the model, and test your thresholds against labeled cases for that provider and model.
+A model alias may change upstream even though Coordinator pins the configured name.
+Use a stable release identifier when your provider offers one.
+A pure `choose` step applies your policy to the stored answers; the next product operation obtains its own authority.
+A terminal `needs-review` outcome returns control to the caller and creates no approval task.
+
+Before dispatch, Coordinator saves the exact prepared request without credentials.
+The validated result and next checkpoint are committed together, so restarting or reading a completed step does not evaluate again.
+After possible dispatch, a lost or malformed reply leaves the call uncertain.
+Inspection reports `hold-after-dispatch`; automatic retry, `retry-same`, and receipt reconciliation cannot repeat that evaluation.
+Only a proven non-dispatch failure is retryable.
+Cancel the run and make a separately authorized new start if you accept another potentially billable evaluation with a possibly different answer.
+Cancellation does not retract provider processing.
+Status keeps `uncertain: true` and reports `cancelRequested: true`.
+After a restore, complete execution recovery may abandon that cancelled evaluation once its active lease has ended and its protected request has been checked.
+Releasing the restore hold then permits unrelated work while retaining the unknown outcome and preventing replay of the cancelled run.
+Unknown product mutations do not qualify for this recovery path.
+
+Contract tests use local HTTP fixtures for both profiles and the documented System One compatible local-provider shape.
+Offline scenarios test policy, refusal, and uncertainty; they do not establish live model compatibility or decision accuracy.

+## Caller authentication
+
+`deployment.authentication` names the token issuer, the admitted client IDs and each client's policy.
+The service reads a token's scopes from its `registry_scopes` claim.
+For an issuer that puts them in the standard `scope` claim, set `scopeClaim: scope`:
+
+```yaml
+deployment:
+  authentication:
+    scopeClaim: scope
+```

+
+## Application integration
+
+A deployment serves each listed flow from its own active package; a start names its flow, and existing runs retain their original definitions.
+Plan and apply change one flow's package without touching another flow's package or runs.
+A flow leaves the deployment only through `--remove-flow`, which is refused while that flow has runs that are not terminal.
+`GET /v1/runs` returns at most 100 of the caller's most recently admitted runs, newest first, from the flows its policy lists; an operator policy lists every owner's runs in those flows.
+`limit` takes 1 to 100 and defaults to 20, and the list has no paging cursor and no state filter.
+`@registrystack/client` has no Coordinator export.
+Applications compose through the authenticated HTTP API and the owning Casework, BReg and optional Messaging APIs.

+## Check commands
+
+The commands in this table come from the maintained format registry.
+
+<ConfigurationFormatChecks product="coordinator" />
+
+Check a project directory, including its optional runtime and scenario files:
+
+```sh
+coordinatorctl check --project ./my-follow-up --explain
+coordinatorctl test --project ./my-follow-up
+```
+
+The project check examines YAML files at the project root. It skips `.coordinator` state and
+reports an incomplete-check warning for other child directories. Optional companion files can
+be absent. Check a runtime file on its own with `--runtime-config`; a relative path is read from
+the current directory:
+
+```sh
+coordinatorctl check --runtime-config ./runtime.yaml --deny-warnings
+```
+
+The `coordinator` service itself requires an absolute runtime configuration path without `.` or
+`..` components.
+
+Without `--environment`, environment expressions defer value checks and produce warnings where
+validation is incomplete. Add `--environment` to check substituted values explicitly.
+`--deny-warnings` makes warnings fail the check. Add `--format json` for a structured report
+containing a diagnostics array. Refusal diagnostics identify the affected file or configuration
+path and suggest a repair. Source positions are included when the error can be tied to source text.
+
+When a check refuses a file, repair the indicated key or reference and run the same check again.
+Use the format registry's header and schema. Keep logical connection names consistent between the
+project and runtime files. An accepted offline check does not activate a package or establish
+deployment readiness.

+# Deploy Registry Coordinator
+
+You operate one Coordinator service beside PostgreSQL 17 or newer and the
+institution's existing OIDC issuer. Receiving Registry Stack products still
+verify their own caller and task authority. Coordinator runs finite reviewed
+workflow packages, one per flow, and preserves every admitted run's original
+definition.
+
+## Deployment checklist
+
+Do these tasks in order. Each one links to the section with the details.
+
+1. [Install the binaries and build each flow's package](#install-and-package).
+   Record the package digest that `package` prints.
+
+   ```sh
+   coordinatorctl package --project ./follow-up --output ./follow-up-package
+   ```
+
+2. [Create the keys and secrets](#create-the-keys-and-secrets) as the service
+   user: the payload state key, the admission key, the audit key and the two
+   database URLs.
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/state-key-1 32)
+   ```
+
+3. [Create the database and roles](#create-the-database-and-roles) as a
+   PostgreSQL administrator, with the SQL in that section.
+
+4. [Write the runtime file](#configure-the-deployment), pin each package digest
+   in `deployment.packages`, and check the file offline.
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml check
+   ```
+
+5. [Apply the deployment](#apply-and-start) with the migration credential, then
+   check it with the runtime credential. `plan` and `apply` verify each pinned
+   package.
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml plan
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml deployment-status
+   ```
+
+6. [Start the service](#apply-and-start) under your supervisor. The service
+   takes the absolute path of the runtime file.
+
+   ```sh
+   coordinator --runtime-config /etc/registry-coordinator/runtime.yaml
+   ```
+
+7. [Check health and run doctor](#check-health-and-run-doctor) with an operator
+   token.
+
+   ```sh
+   curl -fsS http://127.0.0.1:8108/health
+   curl -fsS http://127.0.0.1:8108/ready
+   coordinatorctl doctor --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+8. [Scrape the metrics listener](#watch-metrics) from your monitoring.
+
+   ```sh
+   curl -fsS http://127.0.0.1:9108/metrics
+   ```
+
+## Install and package
+
+Build the two local binaries from the maintained checkout. On Linux, install the
+completed binaries in a service-owned executable directory:
+
+```sh
+cargo build --locked --release -p registry-coordinator --bins
+mkdir -p "$HOME/.local/bin"
+install -m 755 target/release/coordinator target/release/coordinatorctl "$HOME/.local/bin/"
+export PATH="$HOME/.local/bin:$PATH"
+```
+
+On macOS arm64, use the maintained packager to include and relocate the exact FIPS
+library linked by this build. A fresh build directory avoids reusing a CMake
+cache configured for a different minimum OS version. Keep each extracted binary
+beside its bundled library and notices; copying the executable alone loses its
+runtime dependency.
+
+```sh
+MACOSX_DEPLOYMENT_TARGET=11.0 CARGO_TARGET_DIR=target/coordinator-install \
+  cargo build --locked --release -p registry-coordinator --bins \
+  --message-format=json-render-diagnostics > coordinator-build.jsonl
+COORDINATOR_FIPS_ROOT=$(python3 - <<'PYTHON'
+import json
+from pathlib import Path
+messages = [json.loads(line) for line in Path("coordinator-build.jsonl").read_text().splitlines()]
+roots = {str(Path(m["out_dir"]) / "build" / "artifacts") for m in messages
+         if m.get("reason") == "build-script-executed" and "aws-lc-fips-sys@" in m.get("package_id", "")}
+if len(roots) != 1:
+    raise SystemExit("expected one exact FIPS build-script library root")
+print(roots.pop())
+PYTHON
+)
+for binary in coordinator coordinatorctl; do
+  python3 release/scripts/macos_fips_packaging.py archive \
+    --binary "target/coordinator-install/release/$binary" \
+    --asset-name "$binary-macos-arm64" --library-root "$COORDINATOR_FIPS_ROOT" \
+    --notice THIRD_PARTY_NOTICES --output "./$binary.tar.gz"
+  python3 release/scripts/macos_fips_packaging.py extract \
+    --archive "./$binary.tar.gz" --destination "./$binary-install" \
+    --expected-executable "$binary-macos-arm64"
+done
+./coordinatorctl-install/coordinatorctl-macos-arm64 --help
+./coordinator-install/coordinator-macos-arm64 --help
+mkdir -p "$HOME/.local/bin"
+ln -s "$PWD/coordinator-install/coordinator-macos-arm64" "$HOME/.local/bin/coordinator"
+ln -s "$PWD/coordinatorctl-install/coordinatorctl-macos-arm64" "$HOME/.local/bin/coordinatorctl"
+export PATH="$HOME/.local/bin:$PATH"
+```
+
+Use the absolute executable paths in your service definition. The operator shell
+links point to the complete install directories; existing link destinations are
+refused.
+The packager refuses an existing output directory or archive and checks the
+linked library's deployment target. Retain the complete install directories.
+
+Create and check the governed workflow package:
+
+```sh
+coordinatorctl init --directory ./follow-up
+coordinatorctl check --project ./follow-up --explain
+coordinatorctl package --project ./follow-up --output ./follow-up-package
+```
+
+`package` writes one immutable `definition.json` snapshot and `SHA256SUMS`.
+When the project has a `scenarios.yaml`, `package` runs it first and writes
+nothing unless every case passes.
+Install the directory read-only, record the returned package digest, and pin it
+as that flow's `deployment.packages` entry, with `root` and `expectedDigest`.
+[Package digest and definition digest](#package-digest-and-definition-digest)
+explains which of the two digests to pin.
+One project is one flow and one package; its workflow ID is the flow name
+callers start. A deployment lists one pinned package per flow, up to sixteen.
+Offline checks and startup refuse an empty list, a package root or digest
+listed twice, and two packages with the same workflow ID, each naming the entry
+to fix. [two-flow-runtime.yaml](examples/two-flow-runtime.yaml) serves the
+delayed follow-up and governed action examples from one deployment. Runtime files, endpoints, credentials,
+state keys and audit custody are deployment configuration, outside the package.
+Existing output is never overwritten. Build a fresh directory for each update.
+Use `coordinatorctl test --project DIR` for projects with `scenarios.yaml`.
+Once a workflow version has admitted runs, change its version when changing its
+definition. Apply checks retained history, including terminal runs and erased
+payload tombstones, before activating a reused version.
+
+### Package digest and definition digest
+
+A package has two digests. Pin the package digest.
+
+- The definition digest is the SHA-256 of `definition.json`, the workflow
+  snapshot. `check` prints it on its `Definition:` line, and `start`, `status`,
+  `list` and `inspect` report it as `definitionDigest` for each run. A run keeps
+  the definition digest it was admitted under, so after an upgrade it tells you
+  which definition the run follows.
+- The package digest is the SHA-256 of `SHA256SUMS`. That file lists the
+  digest of `definition.json`, so the package digest covers the whole package
+  and changes whenever the definition changes. `package` prints it, `plan`
+  reports it for each flow as `packageDigest` (the listed package) and
+  `activePackageDigest` (the active one), and `deployment-status` reports it
+  for each flow under `flows`.
+
+Put the package digest in `expectedDigest`. `plan`, `apply` and startup check
+the installed directory against it and refuse a package whose content no
+longer matches with `coordinator.deployment.refused` and the advice to restore
+the exact pinned package. `flowsDigest` identifies the whole set of pinned
+packages; the `active` activation record in `plan`, `apply` and
+`deployment-status` carries that set digest in its `packageDigest` field.
+When a workflow version that already admitted runs would name a different
+definition digest, `plan` and `apply` both refuse with
+`coordinator.command.workflow-version-conflict` and the advice to give that
+flow's changed definition a new `project.version`; `apply` keeps the active
+package. A run admitted after `plan` can still make `apply` refuse.
+
+## Create the keys and secrets
+
+Create every secret as the user that runs `coordinator` and `coordinatorctl`.
+A `secret:file/NAME` reference reads the file `NAME` directly under the file
+provider's `root`. That file must be a regular file owned by that user, with
+mode `0400` or `0600` and exactly one link. A `secret:env/NAME` reference reads
+an environment variable when `secretProviders` declares `environment: {}`.
+
+Coordinator uses three kinds of key. Each one is exactly 32 raw random bytes
+in its own file:
+
+- A payload state key encrypts the run state held in PostgreSQL.
+  `deployment.stateKeys` lists its versions and `activeStateKey` names the
+  version that writes.
+- The admission key derives start identities, owner hashes and command keys,
+  so it determines the spent-key namespace. It stays the same for the
+  deployment's lifetime, and it must differ from every state key.
+- The audit key derives the keyed private references in the audit journal.
+
+Create the secret directory and the three key files:
+
+```sh
+install -d -m 0700 /run/registry-coordinator/secrets
+(umask 077 && openssl rand -out /run/registry-coordinator/secrets/state-key-1 32)
+(umask 077 && openssl rand -out /run/registry-coordinator/secrets/admission-key 32)
+(umask 077 && openssl rand -out /run/registry-coordinator/secrets/audit-key 32)
+```
+
+Reference them from the runtime file:
+
+```yaml
+deployment:
+  auditKeyRef: secret:file/audit-key
+  activeStateKey: 1
+  stateKeys:
+    "1":
+      keyRef: secret:file/state-key-1
+  admissionKeyRef: secret:file/admission-key
+```
+
+Key versions are canonical decimal integers from 1 through 4294967295; zero is
+never an active or retained version, and a deployment lists at most 16 versions.
+Offline checks reject invalid versions before resolving key material. Keep keys
+and database backups under separate custody. [Rotate and replace
+keys](#rotate-and-replace-keys) gives the procedure for each key.
+
+The database URLs are secrets too. `database.runtimeUrlRef` names the runtime
+role's URL and `database.migrationUrlRef` the migration role's URL; only
+`apply` resolves the migration URL. Institutional connections use
+`sslmode=require`:
+
+```sh
+(umask 077 && printf '%s' 'postgresql://coordinator_runtime:<runtime-password>@db.example.org:5432/coordinator?sslmode=require' \
+  > /run/registry-coordinator/secrets/runtime-database-url)
+(umask 077 && printf '%s' 'postgresql://coordinator_migration:<migration-password>@db.example.org:5432/coordinator?sslmode=require' \
+  > /run/registry-coordinator/secrets/migration-database-url)
+```
+
+```yaml
+database:
+  runtimeUrlRef: secret:file/runtime-database-url
+  migrationUrlRef: secret:file/migration-database-url
+```
+
+[single-flow-runtime.yaml](examples/single-flow-runtime.yaml) reads the same
+two URLs from environment variables instead.
+
+Write each connection credential the runtime file names the same way, such as
+the signing key an `authorization.signingKeyRef` names. Secret values never
+appear in a diagnostic or a log.
+
+## Create the database and roles
+
+Use PostgreSQL 17 or newer; apply and startup refuse an older server. As a
+PostgreSQL administrator, create the migration role, the runtime role and the
+database, and let only those two roles connect:
+
+```sql
+CREATE ROLE coordinator_migration LOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE
+  NOINHERIT NOBYPASSRLS PASSWORD '<migration-password>';
+CREATE ROLE coordinator_runtime LOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE
+  NOINHERIT NOBYPASSRLS PASSWORD '<runtime-password>';
+CREATE DATABASE coordinator;
+REVOKE ALL ON DATABASE coordinator FROM PUBLIC;
+GRANT CONNECT ON DATABASE coordinator TO coordinator_migration, coordinator_runtime;
+GRANT CREATE ON DATABASE coordinator TO coordinator_migration;
+```
+
+These are the only grants you make. The migration role needs `CREATE` on the
+database because `apply` creates the schema the runtime file's `namespace`
+names, and the migration role owns that schema and its tables. A namespace
+starts with `coordinator_` and is at most 60 characters. The runtime role
+needs only `CONNECT`: `apply` grants it, in that schema, `USAGE` on the
+schema, `SELECT`, `INSERT`, `UPDATE` and `DELETE` on `runs`, `jobs` and
+`admission_lock`, `SELECT` on `control`, `coordinator_activations` and
+`coordinator_migrations`, and `UPDATE` on the four recovery-hold columns of
+`control`.
+
+`apply`, `deployment-status` and startup check the runtime role's effective
+authority, including indirect role membership. They refuse a runtime role that
+is a superuser, bypasses row-level security, belongs to the migration role,
+can create objects in the schema, holds `TRIGGER`, or owns objects there. Keep
+the runtime role out of the migration role. Use the runtime role in
+`database.runtimeUrlRef` and set `deployment.runtimeRole` to its name.
+
+Each service process keeps a fixed pool of at most 32 sessions as the runtime
+role, so allow 32 connections per process in the role's connection limit and the
+server's `max_connections`.
+
+## Configure the deployment
+
+Runtime files use the `id.registrystack.org/formats/coordinator/runtime/v1alpha1`
+`apiVersion` and `CoordinatorRuntimeConfig` kind. The shared runtime reader
+checks the envelope, YAML structure and positioned diagnostics before deployment
+values. Offline checking reads no credentials and contacts no endpoint.
+
+Keep the project runtime's `secretProviders`, `database.runtimeUrlRef`, `namespace` and
+logical `connections`. Add the `deployment` block shown in
+[single-flow-runtime.yaml](examples/single-flow-runtime.yaml), adapting the paths, identity,
+issuer and caller policy. The example contains references only. Provision each
+secret separately through its enabled shared provider.
+
+The shared `jwksSource` block selects its variant with `type`, for example
+`type: discovery`. Write `allowedClients` as a nonempty list of exact client IDs;
+Coordinator refuses omission, an empty list and `unrestricted`. Each listed
+client also needs its explicit action and workflow policy. Coordinator reads a
+token's scopes from its `registry_scopes` claim. For an issuer that puts them in
+the standard `scope` claim, set `scopeClaim: scope` under
+`deployment.authentication`.
+
+For `invoke-breg-action`, configure a Base Registry Engine (BReg) connection with
+an ordinary service `authorization` and an explicitly permitted `profile`. Do not configure
+`authorization.taskAuthority` on that connection: this operation accepts no
+Casework grant and has no task-authority fallback. Keep a task-bound record-read
+connection separate when the workflow needs both authority types.
+
+For `external-get`, configure `externalHttpConnections` separately from product
+`connections`. Declare `baseUrl`, exact `paths`, optional `queryParameters`,
+optional ordinary service `authorization`, and the required `responseSchema`
+for `{status, body}`. Omitted authorization permits a public read and never
+borrows the caller's token. The default attempt timeout is 2000 milliseconds
+and the default response limit is 65,536 bytes; both may be reduced. Use HTTPS
+for institutional endpoints; plain HTTP requires an explicit numeric loopback
+address. See the [external directory example](examples/external-directory/runtime.yaml)
+and [configuration reference](../../docs/site/src/content/docs/reference/coordinator-configuration.mdx).
+
+For `evaluate-decision`, bind a logical `decision` connection under
+`decisionConnections`. Select `system-one` or `openai-decisions`, an explicit
+`baseUrl` and `model`, and either `authorization.bearer` with `tokenRef` and
+`principal`, or explicit `authorization.local: {}` on numeric loopback. The
+configured principal identifies the model account across credential rotation;
+ensure a replacement key belongs to that same account. Request and response
+limits default to 65,536 bytes and the attempt limit to 8000 milliseconds.
+These limits can be reduced. Names across all three connection maps must be
+unique, with at most 16 in total.
+
+Review the data your mappings disclose before activating a remote model binding.
+Model calls may incur cost. Inputs and results use Coordinator's existing protected
+state and retention; provider retention remains your provider/account contract.
+A model alias can change upstream even when the local binding is unchanged.
+Use an immutable release/deployment identifier when your provider offers one.
+No failover or model substitution occurs within an admitted command.
+
+An accepted response must include the returned model and provider usage metadata.
+OpenAI Decisions must supply its documented nonnegative token counts; malformed
+metadata leaves the result uncertain rather than advancing the workflow.
+
+If evaluation completion becomes unknown, inspection reports
+`hold-after-dispatch` and refuses `retry-same` and reconciliation. Cancellation
+sets `cancelRequested` while preserving `uncertain` and the attention state;
+it cannot undo provider processing. A separately authorized new start can evaluate
+again, with possible additional cost and a different answer. The
+same conservative hold applies to HTTP 429, including temporary rate limits with
+`Retry-After`: these bindings do not automatically resend an evaluation. The
+[decision example](examples/decision-follow-up/README.md) includes refusal and
+unknown-result cases; terminal `needs-review` returns control to the caller and
+does not create a resumable approval task.
+
+`databaseId` is the deployment's durable logical identity. Keep it constant
+through restarts, credential rotation and compatible package updates. An existing
+identity mismatch refuses startup or apply. Use a distinct identity and namespace
+for an independent deployment.
+
+`deployment.auditFile` must be an absolute path writable by the service user,
+with durable storage and custody appropriate for the institution.
+
+The service listener uses the shared private listener/TLS policy. Use
+`operator-controlled-upstream` behind your controlled TLS terminator. The
+explicit `development-loopback` option binds only loopback and permits local
+plaintext PostgreSQL. Institutional database connections use TLS with
+`sslmode=require`; configure `database.trustedRootCertificateRef` for private roots.
+Configure `observationAuthorization` only on task-bound Scheduling connections.
+Other adapters do not consume that identity; offline validation refuses it there
+instead of presenting an unused credential as part of recovery authority.
+Downstream bindings use HTTPS, or explicit loopback HTTP for supervised local
+fixtures. Token signing-key rotation preserves the registered downstream client
+identity, endpoint, audience, resource, scopes and approved task authority.
+
+`deployment.metricsListener` is optional. When present, its `bind` is required
+and `/metrics` is served on that socket only: the service listener has no
+metrics route and the OpenAPI document lists none. When absent, no metrics are
+served. The address must be a concrete loopback or private address on a
+nonzero port, and must not be the service listener's socket or one a wildcard
+service listener already covers; the configuration check refuses any other
+bind at `/deployment/metricsListener/bind`. The key and its address rule are
+the ones Registry Messaging uses.
+
+```yaml
+deployment:
+  metricsListener:
+    bind: 127.0.0.1:9108
+```
+
+[Watch metrics](#watch-metrics) lists the series it serves.
+
+Caller policies list exact admitted OAuth clients, required scopes, actions and,
+for run actions, allowed flow identifiers. Each verified client resolves one
+policy. Ownership and admission idempotency come from the token's exact verified
+`iss` and `sub`, never input fields. The run actions `start`, `status`,
+`inspect`, `retry-same`, `cancel` and `reconcile` reach only the flows the policy
+lists in `flows`, which is required when the policy lists any of them. The
+deployment-wide actions `doctor`, `restore-hold`, `release-restore-hold`,
+`release-admission-hold`, `complete-execution-recovery` and `retain` act on every
+flow at once, including flows added later, and need `operator: true` on the
+policy. They take no flow list: a policy that lists only deployment-wide actions
+omits `flows`, and the configuration check refuses one that sets it.
+Do not give institutional producers operator authority. A task-exchanged inbound
+token also requires the matching declared assertion issuer for that client.
+
+## Apply and start
+
+```sh
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml plan
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml deployment-status
+coordinator --runtime-config /etc/registry-coordinator/runtime.yaml
+```
+
+`plan` reports, for each flow, whether apply would `install`, `replace`,
+leave `unchanged` or `remove` its package, with the configured and active
+package digests, the `flowsDigest` of the listed set and the observed
+activation/schema, without claiming deployment validity. `deployment-status` checks the pinned packages,
+database identity, supported migration ledger, effective split runtime role,
+narrow control grants and retained live binding compatibility. The connected
+PostgreSQL `current_user`, configured `runtimeRole` and activated runtime role
+must agree. It uses runtime credentials only, never migration
+credentials, and does not migrate, activate or change recovery holds. JSON output
+returns `status: checked`, `databaseId`, `flowsDigest`, `flows` (each flow's
+package digest), `schemaVersion`,
+`runtimeRole` and the checked `active` activation. Refused checks exit nonzero
+with `deployment.refused` for deployment-contract refusals or
+`live-binding-conflict` for incompatible retained bindings, with operator recovery
+advice. This report does not
+replace the service's audit and recovery readiness checks.
+
+Startup verifies package closure, checksum pin, executable ABI, active package,
+database identity, schema, effective runtime role and configured state/audit
+secrets before serving. Startup checks retained live definitions under the
+admission lock before opening
+the normal listener. Endpoint, registered identity, scopes and task authority
+must retain each live run's original binding. New admissions repeat that check
+inside their insertion transaction; worker polls keep their per-job fences
+without rescanning history every poll. Restore the original bindings or use
+`coordinator --runtime-config FILE --recovery-only` to investigate with dispatch
+and admissions disabled. Recovery-only still verifies the active package,
+database, schema, role and custody, and its readiness remains false.
+
+The service writes JSON lines to standard error at the `info` level. A worker
+poll that fails does not stop the service: it logs a warning with the failure
+code, pauses, and repeats the full deployment check before it polls again. The
+pause starts at 1 second and doubles up to 30 seconds while failures continue.
+When that check cannot open a database connection, the worker polls nothing,
+logs `store-unavailable` with the fix `restore database connectivity`, and
+waits out the outage; meanwhile `/ready` answers 503 and admissions answer 503
+with `store-unavailable`. The periodic deployment check in recovery-only mode
+waits out an unreachable database the same way. Any other refusal stops the
+service with exit status 1 and its code and fix on standard error:
+`deployment.refused` for an activation moved by an apply, `state-key-custody`
+for key custody that no longer matches what apply registered. The service logs
+`worker loop resumed` once a poll succeeds again.
+
+SIGTERM or SIGINT stops the service gracefully. The listener accepts no new
+connection and finishes the requests it is answering; the worker leases no
+further attempt and finishes the one in flight. Both get 15 seconds, the
+10-second attempt timeout plus the 5-second lease finalization allowance; the
+service then logs `stopped` and exits 0. Give the supervisor a stop timeout of
+at least 15 seconds before it sends SIGKILL. An attempt still unfinished when
+the 15 seconds end, or when the process is killed, keeps its lease until the
+lease expires; a worker then holds it for operator review, as it holds the
+attempt of a worker that crashed.
+
+Apply serializes activation with database locks, migrates the dedicated schema,
+grants the runtime role, records the verified set of packages in the shared
+ledger and each flow's active package in the control record.
+A refused incompatible live binding must be resolved by restoring the previous
+binding or finishing/reconciling affected work. Compatible definitions govern new
+admissions while old runs keep their encrypted snapshots and command identities.
+Adding an unrelated logical connection does not change a workflow binding digest.
+Reusing an idempotency key returns the original run rather than creating new work.
+
+Startup does not migrate or activate. The service reads its runtime file from
+an absolute path; `coordinatorctl` also accepts a path relative to the current
+directory.
+
+### Check health and run doctor
+
+Probe the private service listener, then ask the service for its own report
+with an operator token:
+
+```sh
+curl -fsS http://127.0.0.1:8108/health
+curl -fsS http://127.0.0.1:8108/ready
+coordinatorctl doctor --url https://coordinator.example.org --token-file /run/operator-token
+```
+
+`/health` answers `{"live":true}` while the process answers. `/ready` answers
+`{"ready":true}`, or HTTP 503 with `{"ready":false}` while the service cannot
+accept work. Every `/ready` probe checks mutable schema, activation, role,
+state-key custody, audit and recovery holds. The retained live-binding scan is
+coalesced and cached for 30 seconds, including failures; a cache miss still waits
+for that scan, so the cache bounds frequency rather than latency. Startup,
+explicit deployment status, admissions and worker transactions retain their
+fresh authoritative checks. Keep health endpoints on the private service listener.
+
+In the doctor report, `activationReady` and `state.auditReady` are `true` on a
+serving deployment. `state.restoreHold` and `state.admissionsHold` are `false`
+until an operator or a restore places a hold. `state.states` counts runs by
+state, `state.uncertain` counts steps whose effect waits for an operator, and
+`state.restoreReviewRequired` counts runs that need restore review.
+`state.oldestDueAt` is the earliest next attempt of a pending step.
+`state.terminalPayloads` counts the terminal payloads retention can erase, and
+`state.oldestTerminalPayloadAt` is when the oldest of those runs ended.
+
+### Add, upgrade, roll back and remove a flow
+
+Each flow's package is applied on its own. One deployment is one trust domain,
+so flows that must not share connections run in separate deployments. To add a
+flow, list its pinned package; to upgrade or roll one back, change only that entry's `root` and
+`expectedDigest` to the new or previous package. Apply reports each flow's
+change and leaves every other flow's active package and runs untouched. Runs in
+flight on a replaced flow keep the definition they were admitted with; new
+starts of that flow use the replacement. Any apply that changes the listed set
+fences services started under the previous set until they restart, so restart
+every service after each apply.
+
+Dropping an entry never retires a flow by itself. Plan and apply refuse an
+active flow missing from the list with `coordinator.deployment.flow-unlisted`
+until it is listed again or named explicitly:
+
+```sh
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml plan --remove-flow governed-action-follow-up
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply --remove-flow governed-action-follow-up
+```
+
+Removal is refused with `coordinator.deployment.flow-live-runs` while the flow
+has a run that retention could not yet erase: running, waiting, uncertain,
+recoverable or awaiting restore review. Let those runs settle or cancel them
+first; removal, unlike replacement, leaves no definition to finish them under.
+Naming a flow that is still listed or not active is refused. A removed flow's
+terminal runs stay readable and inspectable, and starts naming it are refused.
+
+## Watch metrics
+
+Scrape the metrics listener from your monitoring:
+
+```sh
+curl -fsS http://127.0.0.1:9108/metrics
+```
+
+The metrics are Prometheus text (`text/plain; version=0.0.4`, served with
+`Cache-Control: no-store`), and every label is closed:
+
+| Series | Type | Labels |
+|---|---|---|
+| `coordinator_runs_admitted_total` | counter | none |
+| `coordinator_runs_finished_total` | counter | `state`: `finished`, `failed`, `cancelled`, `cancelled-after-effect`, `expired` |
+| `coordinator_step_attempts_total` | counter | `outcome`: `accepted`, `transient`, `permanent`, `maybe-sent`, `unavailable` |
+| `coordinator_authentication_refusals_total` | counter | `reason`: `refused`, `policy`, `unavailable` |
+| `coordinator_dispatch_jobs` | gauge | `state`: `pending`, `leased`, `unknown` |
+
+Counters are per process: each service process starts them at zero and counts
+only its own work, so a restart resets them. They expose every label value from
+the first scrape. A run counts as admitted once its admission commits; a
+repeated idempotency key returns the original run and counts nothing. A run counts
+as finished each time a committed change moves it into a terminal state, whether
+the worker, an operator action or `complete-execution-recovery` made the change.
+A run that recovery, for example `reconcile`, moves from one terminal state to
+another therefore counts under both states, and the `state` series can add up
+to more than the number of runs that finished. Every step attempt the worker makes counts, local steps
+included: `maybe-sent` is an attempt whose effect is uncertain and that waits
+for an operator, and `unavailable` an attempt that ended in an internal error,
+such as an unreadable store, before the step answered. An authentication
+refusal is a bearer credential refused before a caller is resolved: `refused`
+for a missing, malformed or unverified token, `policy` for a verified token no
+caller policy admits, and `unavailable` when the token verifier cannot answer.
+A resolved caller refused an action is not counted here.
+
+`coordinator_dispatch_jobs` is read from the database on each scrape: `pending`
+steps wait for their next attempt, `leased` steps are being attempted, and
+`unknown` steps wait for an operator to settle an uncertain effect. The count
+is a read-only query bounded at 2 seconds. When the database cannot answer,
+that scrape has no `coordinator_dispatch_jobs` samples rather than zeros, and
+the service logs a warning with the failure code. Alert on the gauge going
+absent as well as on its value.
+
+No label carries a flow, run, input, principal or other caller text, and flow
+identifiers are deliberately not a label. A flow is configuration, so labelling
+by it would grow the series with every flow added and keep series for flows
+removed; an attempt whose snapshot cannot be decoded has no trustworthy flow to
+label; and per-flow and per-run detail already lives in the audit journal and in
+`coordinatorctl status` and `inspect`. Log lines carry fixed messages and
+failure codes, never tokens, run inputs, step outputs, command bodies or caller
+text. Bind the metrics listener where only your monitoring can reach it: the
+counts describe the deployment's traffic even though they name no caller.
+
+## Admit and inspect work
+
+Acquire a current audience-bound access token from your institutional issuer.
+Keep it in an owner-readable file; pass its path, never its value, to the CLI.
+Use a stable key file for one logical admission and retain it through recovery.
+Create a synthetic delayed-follow-up input using an application UUID present in
+your approved registry; `sendAfter` is an RFC 3339 time within the workflow deadline.
+
+```sh
+umask 077
+python3 -c 'import uuid; print(uuid.uuid4())' > ./idempotency-key
+cat > ./input.json <<'JSON'
+{"applicationId":"00000000-0000-0000-0000-000000000001","sendAfter":"<RFC3339_TIME>"}
+JSON
+coordinatorctl start --flow delayed-follow-up --input ./input.json --key-file ./idempotency-key \
+  --url https://coordinator.example.org --token-file /run/producer-token
+coordinatorctl status --run RUN_UUID \
+  --url https://coordinator.example.org --token-file /run/producer-token
+coordinatorctl inspect --run RUN_UUID \
+  --url https://coordinator.example.org --token-file /run/operator-token
+```
+
+`start` sends `{ "flow": "delayed-follow-up", "input": ... }` to `POST /v1/runs`
+with the idempotency key as `Idempotency-Key`. Status and list show authorized
+progress and the reviewed terminal projection. Inspection shows bounded durable
+step state. It never returns original inputs, raw product responses or prepared
+command payloads.
+
+Inspection includes `recovery.operation` for a compatible current call, with its
+pinned ID, version, product, effect, key/preparation requirements, recovery and
+`readReceipt` capability. When inspection can otherwise proceed, it omits the
+field if no compatible current call is available, including pure steps, erased
+payloads or incompatible snapshots. An unresolved original binding can still
+refuse inspection. BReg action invocation declares `same-command` recovery
+and `readReceipt: false`. `retryAllowed` and `reason` describe scheduling
+eligibility; neither the descriptor nor that eligibility proves current product
+authority or the existence of an original-key receipt.
+
+A start is admitted under the named flow's active definition; retained runs
+keep their original definitions. A caller whose policy does not list the flow
+is refused with HTTP 403 `access.denied`; an allowed flow this deployment does
+not serve is refused with HTTP 404 `flow-absent`. `GET /v1/runs` returns at
+most 100 of the caller's most recently admitted runs, newest first, from the
+flows its policy lists; an operator policy lists every owner's runs in those
+flows. `limit` takes 1 to 100 and defaults to 20. The list has no paging cursor
+and no state filter, so keep the run ID a start returns to read an older run
+with `GET /v1/runs/{run}`. Use the
+authenticated HTTP API for application integration; `@registrystack/client`
+has no Coordinator client.
+
+Settled terminal history remains inspectable with its recorded binding identity
+after an old connection is retired. This requires no runnable/uncertain job or
+outstanding restore review; a failed label alone does not qualify. Unresolved
+and recoverable work still requires its original configured connections.
+
+The authenticated operator surface also exposes `doctor`, `cancel`, `reconcile`,
+`retry-same`, `restore-hold`, `release-restore-hold`,
+`release-admission-hold`, `complete-execution-recovery` and `retain`. Use the command's
+`--help` for its exact arguments. Supply a bounded investigation reference such
+as `incident-2026-10-09`; reasons must not contain personal data. The audit request
+records a keyed `reasonRef`, scoped to the logical database and shared across
+recovery actions. Raw investigation references stay outside the audit stream;
+operators retain the external investigation record. Authenticated,
+authorized requests with an empty, overlong or control-character reason, or an
+out-of-bounds retention cutoff/limit, return HTTP 400. State and recovery
+conflicts return HTTP 409. Recovery POSTs authenticate and authorize before
+releasing malformed-body errors. They require `application/json` or an
+application media type ending in `+json`; unsupported or absent media types return
+415 only after authorization. Bodies remain bounded to 65,536 bytes and duplicate
+or unknown fields are refused. Doctor exposes
+state counts, aged work, uncertain effects, eligible terminal payload counts and
+oldest terminal payload time, hold and audit readiness without
+personal labels or payload values.
+
+## Recover safely
+
+The Coordinator retries a call on its own only after a definite retryable
+answer, one the receiving product reports it did not act on, and it resends the
+saved command and key. A call step makes at most ten attempts, waiting about
+1, 2, 4, 8, 16, 32, 64, 128 and then 256 seconds between them; each wait falls
+between half and all of that delay. The nine waits therefore add up to between
+255.5 and 511 seconds, about 4.3 to 8.5 minutes, plus up to 10 seconds for each
+attempt. When the Messaging client or an external service reports a
+`Retry-After` in whole seconds, the next attempt waits at least that long, up to
+five minutes, so the waits never exceed 45 minutes in total. The BReg and
+Scheduling clients report a rate limit without a wait, so those calls follow
+the schedule alone. Every retry is bounded by the run deadline: a retry that
+would start at or after it is never scheduled, and the run ends `expired` with
+the call's failure code. After the tenth attempt the run reports `failed` with
+that code and waits for the recovery below. Uncertain answers are never
+retried automatically.
+
+An `external-get` reply with status 429, 502, 503 or 504 is a definite
+retryable answer on every attempt but the tenth: 429 retries as
+`external-rate-limited` and the others as `external-unavailable`. The tenth
+attempt delivers that status to the workflow like any other, held to the
+connection's `responseSchema`, so the workflow sees a busy status only after
+the retries run out. A run deadline that ends the retries first ends the run
+`expired` with the retry code instead. The ten attempts can span up to about
+nine minutes, and longer when the service sends `Retry-After`.
+
+Inspect before retrying. For Messaging and Scheduling, `reconcile` asks the
+receiving product for authoritative evidence of the stored command using its
+original key and owner. Missing or expired receipts and an unavailable receiver
+do not prove absence. `retry-same`
+uses the durable original body, key, binding and authority only when the receiver's
+recovery contract and original deadline permit it. A fresh idempotency key is a fresh
+operation, so it is never a recovery procedure.
+
+BReg action invocation has no read-only action receipt. `reconcile` therefore
+leaves an uncertain action unresolved. Do not infer success or absence from an
+ordinary record read. Same-command retry retains the saved client preparation,
+conditional ETags and key, and checks current metadata and fresh authority before
+dispatch. A changed contract, denied authority or stale condition safely stops
+the call rather than refreshing its command. Preparation does not mutate BReg;
+cancellation, restore holds and the original workflow deadline still fence
+dispatch. Task-bound operations retain their original approval deadline too.
+
+If a product call succeeds but the following wait mapping is invalid, the run
+reports `failed` with `mapping-invalid` while retaining that call's successful
+output and delivered job. `retry-same` cannot repeat the accepted call. Inspect
+the existing effect before planning any new run with a corrected workflow
+version. Settled failure payloads follow the same explicit retention policy;
+recoverable failed jobs and uncertain effects remain protected.
+
+A computed call input outside its operation input contract fails the run with
+`invalid-command` before the call is prepared, saved or sent. The run and step
+status report `failurePath`, the RFC 6901 path into the input, and never the
+value; an unexpected member is reported at the object that holds it. Correct the
+mapping in a new workflow version, or correct the data it reads, then start a new
+run.
+
+Scheduling connections with `authorization.taskAuthority` require
+`observationAuthorization` with ordinary receipt-read scopes and no
+`taskAuthority`. Configure the same token endpoint, registered client and
+resource as the mutation authorization. Scheduling requires the verified
+issuer and subject to match the original receipt owner. This read credential
+must work independently of the original grant's expiry or revocation. Recovery
+never requests a Casework assertion or exchanges a task token; unavailable read
+authority leaves the effect unresolved. Observation credentials never authorize
+Coordinator dispatch.
+
+Cancellation prevents future dispatch where possible. It does not roll back an
+appointment, governed action or message the receiving product accepted.
+Unresolved external effects remain uncertain until authoritative observation resolves them. Restore
+the original downstream binding if configuration drift blocks recovery. Rotate
+key material under the same registered identity rather than changing the identity.
+
+`retain --before TIMESTAMP --limit N` erases eligible terminal payloads while
+preserving bounded receipts/tombstones for spent start and command identities.
+It does not erase live or uncertain work. Select the cutoff from your institution's
+approved retention policy. Removing state keys before retained ciphertext is
+erased makes that state unreadable and prevents safe execution or disclosure.
+
+## Rotate and replace keys
+
+Each key has its own procedure. Run every command as the service user.
+
+### Rotate the payload state key
+
+Rotation adds a key version and makes it the one that writes. Apply registers
+each version in the database, and the deployment keeps every registered version
+for its lifetime: runs written under an older version still read with it.
+
+1. Create the key file for the next version:
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/state-key-2 32)
+   ```
+
+2. Add the version to `deployment.stateKeys`, keep every version already
+   listed, and set `activeStateKey` to the new version:
+
+   ```yaml
+   deployment:
+     activeStateKey: 2
+     stateKeys:
+       "1":
+         keyRef: secret:file/state-key-1
+       "2":
+         keyRef: secret:file/state-key-2
+   ```
+
+3. Put the edited runtime file and the new key file in place for every
+   service, then apply the deployment and check it:
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml deployment-status
+   ```
+
+4. Restart every service with the edited runtime file as soon as apply
+   succeeds.
+
+Roll the edited runtime file out together with apply. Until apply registers the
+new version, startup and `deployment-status` refuse the edited file with
+`state-key-custody` and the fix to run apply. Once apply has registered it,
+every service still running with the previous file refuses with
+`state-key-custody` until it restarts with the edited file. An ordinary service
+answers starts with 409 and `/ready` with 503, and its worker's next poll
+dispatches nothing and stops the service with exit status 1. A recovery-only
+service stops the same way at its periodic deployment check, every 30 seconds.
+
+Apply, `deployment-status` and startup refuse with `state-key-custody` a runtime
+file that omits a registered version or names different key bytes for it, and
+name `deployment.stateKeys` as the fix. Keep every registered key file under
+backup custody, because a restored database needs the versions its rows were
+written with.
+
+### Rotate the audit key
+
+The audit key derives the keyed references in the audit journal, such as
+`runRef`, `actorRef`, `stepRef` and `reasonRef`. The database holds no record
+of it, so a rotation needs no apply.
+
+1. Create the new key file:
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/audit-key-2 32)
+   ```
+
+2. Point `deployment.auditKeyRef` at it:
+
+   ```yaml
+   deployment:
+     auditKeyRef: secret:file/audit-key-2
+   ```
+
+3. Check the runtime file, then restart every service with it, so all of them
+   write under the same key:
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml check
+   ```
+
+The same run, actor, step or reason gets a different reference under each key,
+so records written before the rotation do not join records written after it.
+Keep the old key with the journal it wrote: an investigator needs it to match a
+known run or actor to those records.
+
+### Replace a compromised admission key
+
+The admission key stays the same for the deployment's lifetime: apply refuses a
+runtime file with a different admission key with `state-key-custody`. When the
+key is exposed, close the deployment and admit new work in a fresh one.
+
+1. Stop admissions. Remove `start` from each caller policy's `actions`; remove
+   a policy left with no action, and its client from `allowedClients`. Restart
+   the service. Starts are then refused with HTTP 403 `access.denied`, while
+   status, inspection and operator actions keep working. Do not use
+   `restore-hold` for this step: it also stops dispatch, so runs in flight
+   cannot finish.
+
+2. Let runs finish, or cancel the ones you will not wait for. Doctor counts the
+   runs still `running` in `state.states` and the steps waiting for an operator
+   in `state.uncertain`. `list` shows the newest runs of the operator's flows,
+   up to 100. Settle each uncertain step as [Recover safely](#recover-safely)
+   describes before you stop the service.
+
+   ```sh
+   coordinatorctl doctor --url https://coordinator.example.org --token-file /run/operator-token
+   coordinatorctl list --limit 100 --url https://coordinator.example.org --token-file /run/operator-token
+   coordinatorctl cancel --run RUN_UUID --reason incident-2026-10-11 \
+     --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+3. Stop the service. Keep its runtime file, namespace, keys and audit journal
+   for as long as you need its history: the old runs stay in the old namespace.
+
+4. Create a new admission key file:
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/admission-key-2 32)
+   ```
+
+5. Write a runtime file for the new deployment with a new `namespace`, a new
+   `deployment.databaseId` and the new key, and restore `start` to the caller
+   policies:
+
+   ```yaml
+   namespace: coordinator_follow_up_2
+   deployment:
+     databaseId: coordinator-institution-follow-up-2
+     admissionKeyRef: secret:file/admission-key-2
+   ```
+
+6. Plan, apply, check and start the new deployment:
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime-2.yaml plan
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime-2.yaml apply
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime-2.yaml deployment-status
+   coordinator --runtime-config /etc/registry-coordinator/runtime-2.yaml
+   ```
+
+The new deployment has no record of the idempotency keys the old one spent, so
+an idempotency key reused against it admits a new run. Tell producers to send a fresh
+start only for work the old deployment did not admit.
+
+## Backup and restore
+
+Back up PostgreSQL, all still-needed state-key versions, the stable admission
+key, audit key, durable audit stream and the exact immutable package of every
+listed flow. Preserve
+custody records and test their restore procedure. Never restore only the database
+and manufacture replacement keys. A backup can predate a downstream effect.
+
+Before restoring, stop or externally fence the old service and all workers,
+including replicas using the same database or credentials. Do not start an
+ordinary worker on the restored database. Activate recovery hold through the
+authenticated operator surface first, using an operator-controlled maintenance
+instance started with `coordinator --recovery-only --runtime-config FILE`. This mode serves authenticated recovery operations and never runs worker dispatch. Inspect and reconcile every command that may
+have been sent after the backup, using the receiving product's original-key
+receipt APIs. Receipt expiry limits what can be established: hold unresolved work
+and consult the authoritative product records, never infer non-existence.
+
+Record the external fencing and reconciliation evidence before
+`release-restore-hold`. Release is an accountable operator action; it cannot
+itself prove another deployment has been fenced. Resume ordinary dispatch only
+after that evidence has been reviewed. Preserve the original admission key and
+command identities to avoid turning a restored history gap into a fresh effect.
+
+Restore hold also persists a separate admission hold. Releasing worker recovery
+hold does not reopen ingress. An older backup can omit entire admissions, so
+reconciling the runs it contains does not prove that replaying an omitted
+idempotency key is safe. Keep admissions held until complete PITR/WAL recovery or separately
+retained authoritative admission evidence establishes the full spent-key history.
+An incomplete backup must remain closed to new admissions.
+
+Only after execution hold is released, complete admission history is established,
+and the previous deployment is externally fenced may an explicitly authorized
+operator run `release-admission-hold --recovery-reference REFERENCE
+--admission-history-complete --prior-deployment-fenced`. These flags are audited
+operator attestations, not automated proof. Keep the supporting evidence under
+institutional custody. False or omitted attestations refuse release.
+
+Execution recovery also tracks every unfinished restored run, including rows
+whose commands had not yet been prepared at the backup point. Those rows may
+have progressed externally after the backup. Hold release refuses until each
+review mark is resolved by a final authoritative receipt with no later external
+call, or complete execution history and prior fencing are explicitly attested.
+Do not cancel a restored run to erase its unresolved external-effect history.
+
+A cancelled uncertain evaluation can be abandoned without blocking unrelated
+work forever. Once its active lease has ended, complete execution recovery can
+clear its restore review after validating the protected definition and prepared
+request. Hold release checks those conditions again. `cancelRequested: true`
+and `uncertain: true` remain visible; the request, unknown outcome and spent
+start identity remain retained, and the run can never resume or replay. This
+exception applies only to evaluations with `hold-after-dispatch` recovery.
+Unknown product mutations still require their original recovery procedure.
+
+When complete PITR/WAL or separately retained authoritative execution evidence
+establishes that history, an operator may use `complete-execution-recovery
+--recovery-reference REFERENCE --execution-history-complete
+--prior-deployment-fenced` while execution hold remains. This audited attestation
+clears execution review marks for resolved work. In that same locked transaction,
+it can settle safe expired reads and local steps into held failed work after
+validating their original protected definition and any prepared command. A call that never
+prepared its command can also be held this way, only with complete recovered
+history: command preparation always precedes sending. The same rules apply to
+safe work already held after a lease lapsed, with no uncertain effect or active
+lease. It preserves the original command and deadline, invalidates stale worker
+completions, and starts no work. Prepared mutating commands left pending after
+a definite retryable response are also held as failed work for an explicit
+`retry-same` or cancellation, with their original command, key and deadline.
+A command-free hold keeps zero attempts; it never invents one.
+
+Pending calls that have not prepared a command, and pending waits or local
+steps also become held failed work. Attestation and
+hold release never start these steps automatically. Prepared safe-read retries
+keep their ordinary pending behavior. Explicitly retry a held wait to restore
+its original scheduled instant atomically; a future wait does not advance early.
+Active leases, prepared mutating leased or unknown calls, uncertain outcomes
+and expired receipts remain protected. The cancelled-evaluation exception above
+allows hold release without resolving or discarding the unknown outcome.
+Recovery does not establish an external
+outcome for any of these calls.
+Prepared evaluations restored before recorded dispatch intent also retain the
+conservative hold; the abandonment exception requires recorded uncertainty.
+
+After `release-restore-hold`, inspect safe settled work and use `retry-same`
+only when its original deadline permits it, or cancel and retain it when no
+further execution is appropriate. Calls and waits retain their original
+deadline; local `choose` and `finish` steps can complete under their existing
+semantics. If an active lease later lapses, repeat complete execution recovery
+only when the history and fencing attestations still hold. Releasing the
+hold also requires repeated recovery if a previously active attempt returns a
+definite retryable result after the first attestation. That prepared mutation
+remains review-required until it is held for the explicit retry or cancellation.
+Releasing the execution hold does not reopen admission or remove its separate
+history requirement.
+
+### Rehearse in disposable databases
+
+Contributors can run the maintained older-backup rehearsal against two distinct,
+disposable local databases. The rehearsal creates random Coordinator and Messaging
+namespaces, takes an actual PostgreSQL backup before command preparation, accepts
+one real Messaging submission, fences the previous worker, and restores the older
+Coordinator namespace. The restored deployment must remain held and produce no
+second effect when the backup lacks the later execution and admission history.
+
+Use `pg_dump` and `psql` from the same PostgreSQL major version as the test server.
+Do not point either test variable at institutional data or the runtime database.
+
+```sh
+export COORDINATOR_TEST_DATABASE_URL='postgresql://<test-role>@127.0.0.1:5432/coordinator_restore_test'
+export COORDINATOR_MESSAGING_TEST_DATABASE_URL='postgresql://<test-role>@127.0.0.1:5432/messaging_restore_test'
+export COORDINATOR_PG_DUMP=/absolute/path/to/pg_dump
+export COORDINATOR_PSQL=/absolute/path/to/psql
+products/coordinator/scripts/test-restore.sh
+```
+
+A passing rehearsal proves this controlled older-backup boundary. Your institution
+still needs its own backup custody, complete history recovery, and external
+fencing evidence before reopening a restored deployment.

+# Coordinator product contract
+
+Registry Coordinator is an optional Rust service. It executes reviewed, finite,
+acyclic YAML workflows using bounded pure Rhai functions and maintained product
+clients. One service and PostgreSQL 17 or
+newer are sufficient. Receiving products retain authorization and ownership of
+their effects.
+
+## Execution and authority
+
+A workflow can read current records, wait durably, choose a branch, call an
+approved product operation and finish with a declared outcome. The authored
+package contains the graph, functions and schemas; deployment configuration
+binds its logical connections to endpoints and identities.
+
+YAML owns the finite graph, waits and the references that carry values between
+steps; pure Rhai computes values and selects an authored branch. `coordinatorctl
+check` fits every reference, literal and `fields` mapping to the schemas it reads
+and feeds before any run. Functions cannot make calls, acquire credentials or add
+runtime steps.
+They read no clock: `add_seconds` and `seconds_between` compute only over the
+RFC 3339 instants they are given.
+
+The eight supported operations are `read-record`, `submit-message`,
+`read-scheduling`, `read-availability`, `create-appointment`, `invoke-breg-action`,
+`external-get`, and `evaluate-decision`.
+Messaging submission and Scheduling appointment creation support same-command
+recovery and read-only original-key receipts. Base Registry Engine (BReg) action
+invocation supports same-command recovery without a read-only action receipt. The four read
+operations can be read again.
+
+`invoke-breg-action` uses a standing BReg service identity and an explicitly
+permitted profile for an immediate governed action. Its input contains `action`
+and an `input` object, with no grant field or task-authority fallback. The maintained
+BReg client prepares the conditional request without mutation. Coordinator saves
+that preparation and original key before dispatch. Recovery checks current
+metadata and fresh authority while retaining the saved request and condition
+ETags. Changed contracts, stale conditions and revoked authority do not silently
+produce a replacement command. An ambiguous response remains uncertain; a
+record read or operator assertion cannot establish action success.
+
+`external-get` is a configured read boundary: operators bind a base URL, exact
+paths, allowed query parameter names, optional service authorization and a local
+response schema through `runtime.externalHttpConnections`. Calls can supply only
+a permitted path and query values. The adapter sends GET, refuses redirects and
+validates the complete `{status, body}` response. Status 429, 502, 503 and 504
+are retried within the run deadline, and the workflow sees one only after the
+retries run out. It provides no external write operation or receipt. Omitted
+authorization means a public read.
+
+Each run keeps its original definition and prepared commands. A repeated
+idempotency key under the same verified issuer, subject and flow returns its
+original run when the input matches. A conflicting input is refused. New compatible package
+versions apply to new starts; existing runs keep their pinned definitions.
+A workflow ID and version identify one definition throughout retained run
+history, including payload-erased tombstones. Apply refuses a changed definition
+under a previously used version; give that definition a new version.
+
+Snapshots pin the capabilities of every used operation. A changed definition
+digest may require a new authoring version under the same history rule.
+
+Credentials are acquired when a call is attempted. A wait, retry or restart
+cannot extend a Casework approval deadline or change its principal, resource,
+scopes or bounds. Receiving products verify current authority. Standing read
+authority and read-only receipt observation cannot authorize a commitment.
+Preparation and dispatch remain subject to cancellation, recovery holds and the
+original workflow deadline. A retry cannot renew an original approval deadline.
+
+An accepted Messaging submission is distinct from provider delivery. A failed
+connection or lost response after sending may leave the effect unknown. The
+original command and idempotency key are retained for bounded recovery.
+If evaluating the following wait fails, the successful call and its output stay
+recorded. The run fails with `mapping-invalid`; the accepted call cannot be
+replayed to repair the mapping.
+A computed call input is held to its operation's input contract before it is
+prepared, saved or sent. An input outside it fails the run with
+`invalid-command`, and the run and step status name where in `failurePath`, an
+RFC 6901 pointer into the input. The computed value is not recorded, and an
+unexpected member is reported at the object that holds it.
+
+`evaluate-decision` uses an explicitly configured System One or OpenAI Decisions
+protocol binding, bounded state and typed questions. Preparation is inert; the
+exact request is saved before dispatch and the validated result is committed
+with the next checkpoint. Evaluation is neither a repeatable read nor a Registry
+mutation. Possible dispatch marks the result uncertain. Without proven provider
+replay or original-result lookup, automatic and operator replay are refused.
+A completed result is reused on restart. OpenAI per-question refusal is a typed
+answer. A System One HTTP refusal stops
+the call; it is not a negative answer or a typed review result. A malformed or
+lost reply remains an uncertain call. HTTP 429 also remains held, including a
+temporary rate limit with `Retry-After`; it does not permit automatic resend.
+Accepted responses require the returned model and valid provider usage metadata.
+Pure workflow policy interprets results before a separately authorized effect.
+Model identity and native confidence are retained without claiming immutable
+weights, determinism, accuracy or interchangeable confidence calibration.
+
+## Deployment and custody
+
+`coordinatorctl` checks, explains and tests projects offline, builds immutable
+packages, plans and applies activation, and operates the authenticated API.
+`coordinator` serves the activated packages without migrating at startup. Only
+explicit apply resolves migration credentials. A split runtime database role
+cannot migrate, activate or replace the custody markers.
+
+Package closure and checksums, executable ABI, database identity, runtime role
+and live connection compatibility are checked before execution. Apply refuses
+incompatible live bindings. Health separates process liveness from readiness;
+doctor reports activation, audit, recovery holds, aged work and retention counts.
+
+Inputs, responses, prepared requests and outcomes are authenticated ciphertext,
+including copies retained by Dispatch. Associated data binds ciphertext to its
+database, run, purpose and step. Payload key versions have immutable registered
+bytes; new versions require apply and retained versions remain available. The
+separate admission key preserves command identity across payload key rotation.
+Secrets are references and never belong in authored packages.
+
+Verified caller policy and ownership govern start, progress and recovery APIs.
+Operator authority is explicit. Durable audit precedes protected actions and
+release of protected results. Recovery investigation references are retained as
+keyed audit handles, never raw operator text. Retention erases eligible terminal
+payloads while keeping spent-key tombstones. Live, uncertain and restore-review
+work cannot be silently erased.
+
+A deployment serves up to sixteen flows, each from its own pinned package,
+which is applied, upgraded, rolled back and explicitly removed on its own. One
+deployment is one trust domain, so flows that must not share connections run in
+separate deployments. A start names its flow and is admitted under that flow's active definition, while
+retained runs use their original versions. A flow with runs that are not
+terminal cannot be removed. A caller policy's `flows` scopes its run actions
+only. Deployment-wide operator actions reach every served flow, including flows
+added later, and require `operator: true` instead of a flow list.
+`GET /v1/runs` returns at most 100 of the caller's most recently admitted runs,
+newest first, from the flows its policy lists; an operator policy lists every
+owner's runs in those flows. `limit` takes 1 to 100 and defaults to 20. The list
+has no paging cursor and no state filter. Applications use
+the authenticated HTTP API; `@registrystack/client` has no Coordinator export.
+
+## Recovery and limits
+
+The canonical definition snapshot is limited to 393,216 bytes across authoring,
+packages and restore. `check` and `package` refuse a larger snapshot before
+writing a package. Reduce schema annotations or function source when escaping
+makes the canonical snapshot exceed this limit. A noncanonical snapshot must
+fit both the incoming byte limit and the same canonical byte limit.
+
+Inspection, same-command retry, authoritative receipt reconciliation and
+cancellation use supported APIs. Operator text and an arbitrary receipt ID are
+not evidence that an external command succeeded. Cancellation stops future
+dispatch where possible and reports accepted or unresolved effects without
+claiming rollback.
+
+A restored deployment first runs in recovery-only mode and establishes a
+persistent hold. The previous deployment must be externally fenced. Every
+unfinished restored run requires review, including rows saved before command
+preparation. Missing or expired receipts do not establish that no effect took
+place. Incomplete execution history stays held; reopening unknown admissions
+requires a separate explicit complete-history and fencing attestation. Complete
+execution recovery may settle safe expired reads or local steps into held
+failed work using their original protected definitions and commands, including
+safe work already held after a lease lapsed. Calls that never prepared a
+command are also eligible under the complete-history and fencing attestations,
+since command preparation always precedes sending. This transition invalidates
+stale worker completions and never starts work or claims success. Active
+leases, prepared mutating leased or unknown calls, uncertain outcomes and
+expired receipts stay protected. A prepared mutating command pending after a definite
+retryable response is held as failed work, preserving its original command,
+key and deadline until explicit same-command retry or cancellation. Active work
+keeps its review mark so a later retryable result requires another recovery
+decision before hold release. After hold release, an operator may retry the
+held work within its existing deadline, or cancel it. Calls and waits retain their
+deadlines; local `choose` and `finish` steps keep their existing completion
+semantics. See the [deployment runbook](DEPLOYMENT.md) for the procedure and
+executable restore test.
+
+An uncertain evaluation with `hold-after-dispatch` recovery may be cancelled
+and explicitly abandoned during complete execution recovery once its active
+lease has ended. The protected definition and original prepared request must
+match. Release rechecks eligibility and allows unrelated work to resume while
+retaining `uncertain`, `cancelRequested`, the original request and spent start
+identity. It never resumes the cancelled run or establishes its remote outcome.
+Unknown product mutations do not qualify for this exception.
+
+`coordinatorctl check --project DIRECTORY` checks `workflow.yaml` and
+`functions.rhai`, plus optional `runtime.yaml` and `scenarios.yaml` companions.
+Every YAML or YML file in the project root must have its supported envelope
+and owned filename. The check aggregates companion errors and executes valid
+scenarios against the loaded workflow. It reads only the root, with at most
+1024 entries; other child directories produce an incomplete-check warning.
+The owned `.coordinator` state and secret directory is never traversed.
+Runtime checks remain offline unless `--environment` is selected and never
+resolve secret values. An explicitly supplied runtime is checked once.
+
+Scenario files use `kind: CoordinatorScenarios` and the API version
+`id.registrystack.org/formats/coordinator/scenarios/v1alpha1`. Each case has a unique local `id`. Replies name their `type`: `success` carries a
+foreign JSON `value`; `retryable`, `refused` and `uncertain` carry a `code`;
+`receipt-expired` has no additional members. Inputs, successful replies and
+expected outputs are foreign JSON values, including explicit nulls, while
+ordinary scenario configuration follows the shared reader rules. An omitted
+expected outcome is not checked; `{type: none}` checks its absence and
+`{type: named, value: outcome-id}` checks a declared outcome.
+`workflowElapsedSeconds` checks elapsed workflow virtual time.
+
+Deterministic scenario tests use the same graph and function semantics with a
+virtual clock and fake product replies. They complement PostgreSQL, process
+restart and native-service tests; they do not prove actual downstream effects.
+After a simulated receipt expiry, the run stays uncertain. Neither `retry-same`
+nor `reconcile` can consume another reply, since the supported products cannot
+confirm an original command through an expired receipt. Before receipt expiry,
+a successful, explicitly declared reconciliation represents authoritative
+confirmation of a Messaging or Scheduling command, never a new submission.
+BReg action scenarios cannot declare successful reconciliation without a
+read-only action receipt contract. Reconciliation can resolve an uncertain
+outcome; a definite retryable reply requires
+same-command retry.
+
+The governed-action adapter has both mock HTTP checks and explicit native
+acceptance checks. The first native check observes a committed patch after response
+loss, reconstructs the adapters from saved preparation, and recovers with the
+same body, key and conditions. It verifies one applied record revision, the same
+application receipt, fresh metadata, a real read-only profile refusal and no
+receipt lookup. The second uses actual `Worker` and `Store` objects with a real
+BReg action and Messaging notice. It drops the accepted notice reply, reconstructs
+the objects, and resolves the notice through its exact original receipt lookup.
+Neither action nor notice is repeated; duplicate start admission returns the
+original run. Acceptance does not establish provider delivery. Object
+reconstruction is distinct from OS-process restart, which retains separate
+`process_restart` coverage. PostgreSQL worker checks separately exercise
+preparation and crash durability. The separate `scripts/test-real-services.py`
+journey composes BReg, Casework, Scheduling and Messaging with a persisted wait
+and an actual worker restart.
+See [the contributor checks](README.md#verify-a-change)
+for the explicit helper and its two distinct disposable loopback databases.
+Successful runs clean up UUID-owned fixture resources; assertion failures may
+retain diagnostic Coordinator and Messaging schemas. This explicit contributor
+check is not a CI gate.
+Native Casework and BReg applications may compose a governed application action
+with a separate optional notice through their owning APIs.
+
+Coordinator does not add language builders, a WASM toolchain, dynamic fan-out,
+arbitrary HTTP methods or SQL steps, automatic compensation, or a visual editor.
+It does not promise atomic distributed revocation or rollback of accepted
+effects. Existing hooks and APIs remain available to external orchestrators.
+Coordinator is pre-1.0: this contract, the workflow format, the HTTP API and
+the runtime configuration may still change between releases.

+# Registry Coordinator
+
+Use Registry Coordinator when your institution needs a reviewed sequence of
+Registry Stack calls to continue across durable waits, service outages and
+worker restarts. One optional Rust service executes finite, acyclic YAML plans
+with declarative mappings and bounded pure Rhai functions. PostgreSQL stores encrypted progress and
+prepared commands. Receiving products retain authorization and ownership of
+every external effect.
+
+The [product contract](PRODUCT-CONTRACT.md) describes the supported product boundary; the
+[deployment runbook](DEPLOYMENT.md) covers installation, authenticated access,
+package activation, operation and recovery. Coordinator does not claim
+distributed rollback. It is pre-1.0: the workflow format, HTTP API, runtime
+configuration and deployment contract may still change, so use the binaries and
+documentation of one release together.
+
+## Create and check a project
+
+Run these commands from the maintained Registry Stack checkout. The two binaries
+separate local authoring and deployment operations from the running service.
+
+```sh
+cargo run --locked -p registry-coordinator --bin coordinatorctl -- init --directory ./my-follow-up
+cargo run --locked -p registry-coordinator --bin coordinatorctl -- check --project ./my-follow-up --explain
+```
+
+For the later `coordinatorctl` commands, use the installed executable from the
+[deployment runbook](DEPLOYMENT.md#install-and-package), or the same `cargo run`
+prefix followed by `--`. The starter
+contains `workflow.yaml`, `functions.rhai`, `runtime.yaml` and `scenarios.yaml`,
+plus a `.gitignore` that keeps the local `.coordinator/` directory out of version
+control. Its project id is the directory name unless you pass `--id`. Init writes into
+a new or empty directory and refuses one with content. Check validates the graph,
+function exports, references, input/outcome schemas, the fit of every mapping and
+execution bounds without credentials, network access or database writes. Add
+`--runtime-config ./my-follow-up/runtime.yaml` to check the logical bindings as well.
+
+`workflow.yaml` is a `CoordinatorProject` document. Its `project` block names the
+workflow and version, `deadlineSeconds` states a bounded integer duration, and
+`functionsFile` names `functions.rhai`. Each step declares its `type`: `wait-until`,
+`call`, `choose`, or `finish`.
+
+Mappings carry values between steps, and a reference names one value.
+`{type: input}` reads the workflow input, `{type: step, step: read-application}`
+reads that earlier call's output and `{type: literal, value: applications}`
+supplies an authored JSON value. An input or step reference may add an RFC 6901
+`path`, such as `/data/recordIdentifier`, to select one member. The checker
+proves the referenced call completed on every incoming route. Every mapping names
+its form with `type`. A call `input` or a finish `output` is either
+`type: fields`, an object built member by member from up to 64 references, or
+`type: function`, a pure function with up to 16 reference `arguments`.
+`waitUntil` and `choose` take one reference or `type: function`.
+
+```yaml
+read-application:
+  type: call
+  connection: applications
+  operation: read-record
+  input:
+    type: fields
+    fields:
+      collection: {type: literal, value: applications}
+      recordId: {type: input, path: /applicationId}
+  next: permission
+```
+
+Check fits every mapping to the schemas it reads and feeds before any run. A path
+must name a member the workflow input schema or the call's
+[operation output](generated/operations/README.md) declares; beneath an open
+member any path is accepted. A `fields` mapping must set every member its
+operation input or outcome requires and no member it does not declare. A literal
+must satisfy its member's schema, and a reference cannot read a value declared
+with another type or string format. A `waitUntil` reference must read a date-time
+or plain string. A `choose` reference must read a string; when its schema lists
+the values, the cases must match them exactly. Each refusal names the step, the
+field path, what was expected and the fix: check reports the first refusal in each
+step, in step order.
+The published project schema holds each `fields` mapping to its operation's
+member names in an editor too.
+
+A function's result, and a value read beneath an open member, are known only
+when the run computes them. `coordinatorctl test` holds every computed call input
+to its operation input and every synthetic success reply to its operation output.
+The service holds every computed call input to its operation input before it
+prepares, saves or sends the call. An input outside it fails the run with
+`invalid-command`, and the run and step status report the RFC 6901 path into the
+input as `failurePath`, never the value.
+
+All three configuration formats use the shared strict configuration reader and carry
+editor schema modelines. JSON Schema fragments and scenario payloads retain their
+own JSON value semantics, including nested null values; optional configuration
+members are omitted. Check reports all independent structural errors with file,
+line, column and a repair action, and never repeats a value read from a file or
+the environment. Some errors mask the checks that depend on them, so a repair
+can reveal further errors: a file that cannot be read, or a call to an operation
+Coordinator does not offer, stops the workflow checks; an undeclared start step
+or transition target skips the reachability, cycle and data-flow checks;
+mappings are fitted to schemas only once the workflow, functions and schemas are
+valid; and scenarios run only once the project loads.
+
+Runtime files can also be checked alone:
+
+```sh
+coordinatorctl --runtime-config ./my-follow-up/runtime.yaml check --deny-warnings
+```
+
+The default check does not read environment values or secret material. It warns
+where an environment expression defers a value check. Add `--environment` to
+substitute those expressions explicitly; `--deny-warnings` makes deferred checks
+fail. JSON reports use `CoordinatorCtlReport` on standard output, with `ok`,
+`command`, `status` and a `diagnostics` array for refusals. Exit codes distinguish
+accepted input (0), refused input (1), command usage (2) and unavailable resources
+(3).
+
+`explain --project DIR` lists the steps in graph order from start, one line each,
+with each call's product, effect and recovery contract. `test --project DIR` runs
+the project's `scenarios.yaml` with a virtual clock and fake product replies. It
+uses the same graph, mapping and function semantics as the service. Each case
+is reported by name. With `--format json`, a case that ran also gives the steps
+its run took, the state it ended in and its outcome: identifiers the workflow
+declares, and states the scenarios format accepts. A step, state or outcome
+that differs from the expectation is named on both sides, for example
+`/expect/path/3: expected step notify, observed step skipped`. For any other
+member that differs, such as the output or the elapsed time, the report gives
+the member's JSON Pointer and the class of each side: string, integer, number,
+boolean, null, array, object, or absent. A case lists its first 20
+differences and ends with a line counting the rest, such as `and 5 more
+differences`. A function that fails is reported by the kind of failure and
+its line and column in `functions.rhai`. Neither repeats a value read from a
+file or computed by a run. Scenario tests never
+acquire real credentials or send requests. Commands print readable text by
+default; `--format json` supplies structured reports.

+## Start from a maintained project
+
+- [Delayed follow-up](examples/delayed-follow-up/README.md) waits durably,
+  reads a current Base Registry Engine (BReg) record, chooses a reviewed notice
+  policy and submits one message. Its deterministic scenarios cover permission changes, waits,
+  uncertain responses, frozen command retries and refusals.
+- [Deferred appointment](examples/deferred-appointment/README.md) reads a
+  current BReg record, waits, reads Scheduling availability, books with an
+  explicitly approved Casework deferred grant, then submits a separate Messaging
+  notice. The original grant reference and deadline stay fixed while credentials
+  are acquired freshly. Standing catalogue read authority, booking task authority
+  and Messaging identity are separately configured.
+- [Approved record check](examples/approved-record-check/README.md) exercises
+  a BReg read through explicit Casework task authority.
+- [Governed action follow-up](examples/governed-action-follow-up/README.md)
+  reads an application, invokes a governed BReg action through a permitted service
+  profile, and submits a separate notice through Messaging.
+- [External directory](examples/external-directory/README.md) reads a configured
+  directory over HTTP GET and chooses an outcome from the validated response.
+- [Bounded poll](examples/bounded-poll/README.md) reads a BReg application at
+  three fixed times and finishes with the decision or with `still-pending`, as
+  described in [Waits and polling](#waits-and-polling).
+
+```sh
+coordinatorctl check --project products/coordinator/examples/deferred-appointment --explain
+coordinatorctl test --project products/coordinator/examples/deferred-appointment
+coordinatorctl test --project products/coordinator/examples/delayed-follow-up
+```
+
+Adapt the reviewed functions and owning product policy to your institution. YAML
+declares the finite graph, waits, fixed logical connections and the references
+that carry values between steps. Choose pure Rhai for logic within that graph:
+selecting a branch, building a nested request or computing an instant. Rhai cannot acquire
+credentials, contact products or construct additional steps. There are no SQL
+steps, arbitrary HTTP methods, dynamic fan-out or automatic compensation.
+
+Rhai reads no clock; it computes over the instants it is given.
+`add_seconds(instant, seconds)` returns an RFC 3339 instant moved by a signed
+number of seconds, written in UTC. `seconds_between(first, second)` returns the
+whole seconds from the first instant to the second, truncated toward zero. An
+instant without an offset, or a result outside the years 0000 to 9999, fails the
+function with `function.execution`.
+
+The supported operation inventory is fixed:
+
+| Operation | Receiver | Effect | Recovery |
+| --- | --- | --- | --- |
+| `read-record` | Base Registry Engine (BReg) | Read | Read again |
+| `submit-message` | Messaging | Mutation | Same command and read-only receipt |
+| `read-scheduling` | Scheduling | Read | Read again |
+| `read-availability` | Scheduling | Read | Read again |
+| `create-appointment` | Scheduling | Mutation | Same command and read-only receipt |
+| `invoke-breg-action` | BReg | Mutation | Same prepared command; no read-only receipt |
+| `external-get` | Configured external HTTP service | Read | Read again |
+| `evaluate-decision` | Configured typed decision service | Evaluation | Hold after uncertain dispatch |
+
+`invoke-breg-action` takes an action identifier and an object of action inputs.
+It requires a standing BReg service identity and a profile that permits that
+immediate action. It does not accept a Casework grant or inherit task authority.
+The maintained BReg client owns metadata validation, condition ETags and prepared
+command recovery. Preparation is nonmutating; its exact request and idempotency
+key are saved before dispatch. Later attempts check current metadata and acquire
+fresh credentials without refreshing the saved conditions or key. A changed
+contract, denied authority or stale condition stops the action safely.
+
+`external-get` binds through `runtime.externalHttpConnections`, separately from
+product connections. Operators configure the base URL, exact permitted paths,
+query parameter names, optional service authorization and response schema. The
+workflow supplies only a permitted path and query values. The adapter performs
+GET, rejects redirects, and returns the validated `{status, body}` JSON value.
+A 429, 502, 503 or 504 reply is retried first, as `external-rate-limited` or
+`external-unavailable` with its `Retry-After` as the floor for the next attempt;
+the workflow receives it only on the last attempt, as
+[Recover safely](DEPLOYMENT.md#recover-safely) describes.
+An omitted authorization block means a public read, with no borrowed caller
+credential. See the [configuration reference](../../docs/site/src/content/docs/reference/coordinator-configuration.mdx)
+for limits and defaults.
+
+`evaluate-decision` accepts typed predicate, choice and rubric-score questions.
+Bind its logical `decision` connection under `runtime.decisionConnections` using
+the System One or OpenAI Decisions protocol. The exact request is frozen before
+sending; the validated result is saved before the next step. Rhai can apply
+thresholds to the saved answers, then a separate product call acquires its own
+authority. A refused or uncertain model result grants no authority.
+
+An evaluation may be billable and cannot be treated as a repeatable read. An
+ambiguous dispatch stops without automatic retry, `retry-same` or receipt
+reconciliation. Cancel and make a separately authorized new start if another
+potentially billable evaluation is appropriate. The
+[decision example](examples/decision-follow-up/README.md) demonstrates offline
+branching and distinguishes model refusal from transport uncertainty. General
+structured generation, model tools and asynchronous jobs are not supported.
+
+## Waits and polling
+
+A `wait-until` step waits until one instant: an input value, a value from an
+earlier call's output, or a pure function of them such as `add_seconds`. The
+wait is stored in PostgreSQL, so it continues across service restarts, and an
+instant that has already passed continues the run at once. When a wait ends at
+or after the run's `deadlineSeconds`, the run expires with failure code
+`deadline-reached` instead of taking its next step.
+
+The workflow graph is finite and acyclic: no step leads back to an earlier one.
+A poll is therefore unrolled. Each round is a `wait-until`, a current read and a
+`choose` that either finishes or moves to the next round's wait, and the last
+round finishes with an outcome saying the answer is not there yet. The caller
+reads that outcome and, if it still needs the answer, starts a new run later.
+[Bounded poll](examples/bounded-poll/README.md) reads a BReg application at its
+first check time and one and two days later, then finishes `decided` or
+`still-pending`.
+
+Runs start only from an explicit caller request, through `POST /v1/runs` or
+`coordinatorctl start`. There are no event-started runs, no wait-for-signal
+steps and no completion callbacks: a waiting run continues only when its instant
+passes, and a caller learns the outcome by reading the run's status.
+
+## Add a maintained operation
+
+For an operation on an existing product boundary, add a versioned descriptor in
+`src/operations.rs` under `crates/registry-coordinator`. Declare its product,
+effect, key requirement, preparation requirement, recovery semantics and read-only
+receipt capability. Add the owning client adapter and routing, with focused
+contract and recovery tests. Use the `AdapterSet` preparation seam when the client
+requires a saved prepared command. Product metadata, authorization and wire
+validation remain the maintained client's responsibility.
+
+The operation schema derives from the catalog; regenerate the project schema.
+The worker, store and offline scenario state machine consume those declared
+capabilities. They do not need operation-specific execution branches. Snapshots
+pin exact semantics, so changing a descriptor or its version cannot silently
+reinterpret retained runs. Preserve the original descriptors for compatible
+restore. Add offline scenarios using typed replies and only the declared
+recovery capabilities; passing them does not prove a live product effect.
+Coordinator exports are not generated into a language SDK.
+
+## Package and deploy
+
+```sh
+coordinatorctl package --project ./my-follow-up --output ./follow-up-package
+```
+
+When the project has a `scenarios.yaml`, `package` runs it first and writes
+nothing unless every case passes. The immutable package contains a Definition
+snapshot and shared `SHA256SUMS` closure. It holds reviewed workflow/functions
+and executable ABI identities.
+Endpoints, credentials, private access policies, database identity, encryption
+keys and audit custody remain in runtime configuration. Compatible new packages
+serve new admissions while previously admitted runs keep their original snapshots
+and command identities. A new version cannot reinterpret a repeated idempotency key.
+
+Snapshots pin each used operation's capabilities. A newly packaged definition
+with a changed digest needs a new workflow version if that ID and version
+already exists in retained history.
+
+A project is one flow and packages as one artifact; its workflow ID is the flow
+name callers start. One deployment serves up to sixteen flows by listing one
+pinned package per flow under `deployment.packages`, so each workflow stays one
+reviewed artifact that is applied, upgraded and rolled back on its own.
+[`examples/two-flow-runtime.yaml`](examples/two-flow-runtime.yaml) serves the
+delayed follow-up and governed action examples from one runtime file.
+
+Use [DEPLOYMENT.md](DEPLOYMENT.md) to provision OIDC clients, downstream bindings,
+state-key custody, PostgreSQL split roles and a private listener. Apply explicitly
+migrates and activates the pinned packages, one per flow. The service verifies activation and
+never migrates during startup. Its authenticated admission API derives ownership
+and idempotency scope from exact verified issuer and subject. Input identifiers
+and grant references do not manufacture caller authority.
+
+## Observe and recover
+
+Authenticated status and list expose progress and the reviewed terminal
+projection of the caller's own runs, from the flows its policy lists; an
+operator policy reaches every owner's runs in those flows. Inspection shows bounded step metadata, uncertainty and the
+available recovery action. Operator policy explicitly grants recovery and private
+diagnostics. Run actions reach only the flows a policy lists; deployment-wide
+operator actions such as `doctor` and the restore hold reach every flow and need
+`operator: true` instead of a flow list. Inputs, product responses and prepared commands remain encrypted and
+are absent from these responses.
+
+For a compatible current call, inspection includes `recovery.operation`: its
+pinned ID, version, product, effect, key and preparation requirements, recovery
+semantics and `readReceipt` capability. When inspection can otherwise proceed,
+it omits the field if no compatible current call is available, including pure
+steps, erased payloads or incompatible snapshots. An unresolved original binding
+can still refuse inspection. For example, `invoke-breg-action` declares
+`same-command` recovery with `readReceipt: false`. `retryAllowed` and `reason`
+describe the run's eligibility to be scheduled. The operation descriptor does
+not prove current product authority or the existence of an original-key receipt.
+
+A start names its flow and is admitted under that flow's active definition.
+Previously admitted versions remain available for their existing runs.
+`GET /v1/runs` returns at most 100 of the caller's most recently admitted runs,
+newest first, from the flows its policy lists; an operator policy lists every
+owner's runs in those flows. `limit` takes 1 to 100 and defaults to 20. The list
+has no paging cursor and no state filter, so keep the run ID a start returns to
+read an older run with `GET /v1/runs/{run}`. `@registrystack/client` has no
+Coordinator export.
+Institutional applications compose through its authenticated HTTP API and the
+owning Casework, BReg and optional Messaging APIs.
+
+After a lost Messaging or Scheduling response, reconcile against the receiving
+product's original-key receipt before retrying. BReg action reconciliation remains
+unresolved because no read-only action receipt is available; an ordinary record
+read does not prove that the original action succeeded. Same-command recovery
+preserves the body, key, destination, caller and original task authority.
+An unavailable product or expired receipt never proves that an effect did not
+occur. Messaging acceptance records a
+provider submission contract; provider delivery is a distinct observation.
+Cancellation prevents later dispatch where possible and does not roll back an
+appointment, governed action or notice already accepted by its owning product.
+
+Retention erases eligible terminal payloads while preserving spent-key tombstones.
+A retained run can still be inspected; it cannot be retried or reconciled without
+its erased payload. Restore starts with dispatch and admission disabled. Recovery
+hold marks every unfinished restored run for review, including commands not yet
+prepared at the backup point. Execution history and admission history have separate
+release requirements. The deployment runbook explains the explicit fencing and
+complete-history attestations and the limits of older backups.
+
+## Verify a change
+
+The owning Cargo tests cover authoring, deterministic scenarios, runtime config,
+package integrity, OIDC policy, product adapter boundaries and Scheduling command
+recovery. The PostgreSQL feature gates protect database-dependent suites from
+ordinary workspace test runs.
+
+```sh
+cargo test --locked -p registry-coordinator --features schema \
+  --test authoring --test authored_project --test authored_scenarios \
+  --test cli_authoring --test runtime_config \
+  --test deployment_surface --test http_boundary --test scheduling_adapter \
+  --test breg_action_adapter --test external_http --test external_runtime \
+  --test decision_protocol --test decision_runtime \
+  --test catalog_scenarios
+products/coordinator/scripts/check-schemas.sh
+cargo run --locked -p registry-coordinator --bin coordinatorctl -- openapi \
+  > products/coordinator/generated/openapi/coordinator.openapi.json
+```
+
+With dedicated disposable PostgreSQL 17+ databases configured, use
+`scripts/test-postgres.sh` for the maintained durable-state, encrypted-custody,
+restart, deployment/router and Messaging integration checks. That script first
+builds the independent Messaging service and operator executable, then supplies
+`COORDINATOR_MESSAGING_BIN` and `COORDINATOR_MESSAGINGCTL_BIN` to the tests.
+The integration fixtures compose through Messaging's public HTTP contract and
+refuse missing executables; Coordinator does not link its runtime as a test
+dependency. The native-service
+fixture script runs the controlled BReg, Casework, Scheduling and Messaging
+journey. It requires Python 3, OpenSSL and PostgreSQL client tools, Docker,
+distinct disposable PostgreSQL databases, and all ten native service/operator
+binaries described by the script's `--help`. Those contributor checks do not replace the deployment runbook or imply
+production credentials are needed to author a project.
+
+The governed-action and external-directory examples have deterministic scenarios;
+adapter checks use mock HTTP services and durable-state checks use PostgreSQL.
+For native BReg action and notice acceptance, run this explicit helper from the checkout:
+
+```sh
+python3 products/coordinator/scripts/test-breg-action.py --env /absolute/path/coordinator-test.env
+```
+
+Provide Python 3, the current checkout's Cargo build prerequisites, and
+distinct `COORDINATOR_TEST_DATABASE_URL` and
+`COORDINATOR_MESSAGING_TEST_DATABASE_URL` values in the environment or named file.
+Each URL must name an owned disposable PostgreSQL 17+ database on loopback.
+The Coordinator database identity needs authority to create and drop unique
+fixture databases and roles; both database identities must create and drop
+fixture schemas. The helper builds current `breg`, `bregctl`, `messaging` and
+`messagingctl` binaries and provisions synthetic credentials and data. Successful
+runs clean up UUID-owned fixture resources without resetting the named databases.
+Assertion failures can retain diagnostic Coordinator and Messaging schemas.
+No live service credentials are required.
+
+The first native check proves one governed patch was accepted despite a lost response.
+Reconstructed `HttpAdapters` reload the saved preparation and recover with the
+same body, key and conditions, leaving one applied record revision and returning
+the same application receipt. It checks fresh metadata, refusal through a real
+read-only profile, and no BReg receipt lookup during reconciliation.
+
+The second check executes `Worker` and `Store` through a real BReg action and a
+real Messaging notice submission. After the accepted notice reply is dropped,
+reconstructed objects recover through the exact original notice receipt lookup.
+The action and notice are not resubmitted, and duplicate start admission returns
+the original run. This proves message acceptance, not provider delivery.
+Reconstruction replaces Rust objects; it does not restart the Coordinator OS
+process. The separate `process_restart` target retains process restart coverage.
+The separate `scripts/test-real-services.py` journey composes BReg, Casework,
+Scheduling and Messaging with a persisted wait and an actual worker restart.
+Its default 961-second wait crosses the immediate approval limit. It checks
+fresh credentials bounded by the original deferred approval, original-receipt
+recovery after lost booking and notice replies, and refusal of expired, unknown
+or mismatched approvals without additional effects. Waits shorter than 901
+seconds are smoke checks and do not establish the long-wait boundary.
+The helper is an explicit contributor check, not a CI gate.

+# Approved record check project
+
+Use this synthetic example when a run must read one Base Registry Engine (BReg)
+record under a Casework approval instead of a standing service identity. The
+run waits until the input's `notBefore`, reads the record with the approved
+grant, and finishes with the record identifier. The workflow, deterministic
+scenarios and runtime template form one complete project. `functions.rhai`
+declares no functions, because every mapping is a reference in
+`workflow.yaml`.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/approved-record-check --explain
+coordinatorctl test --project products/coordinator/examples/approved-record-check
+```
+
+The start input carries `collection`, `recordId`, `notBefore` and a `grant`
+with the approval's `id` and its original `expiresAt` Unix timestamp. Copy those
+two grant values from the Casework approval unchanged; the input carries no
+assertion or token. The `read` step passes the grant to `read-record`.
+
+The `source` connection declares `authorization.taskAuthority`, so it accepts
+only grant-bound reads. A read without `grant` is refused with
+`invalid-command`, and so is a grant sent to a BReg connection without
+`taskAuthority`. For each read attempt, including one after a restart, the
+Coordinator acquires authority afresh:
+
+1. The registered client `task-agent` obtains a token for the
+   `bootstrapResource` `urn:example:casework` with scope
+   `casework:grants:assert`.
+2. It asks Casework at `taskAuthority.baseUrl` for an assertion about the
+   grant. Casework must report the same grant deadline as `expiresAt`.
+3. It exchanges that assertion at the token endpoint for a BReg token for
+   resource `urn:example:applications` with scope `records:get`, bound to the
+   configured `issuer`, `subject` and `exchangeAudience`.
+
+No bearer is kept between attempts, and there is no fallback to standing
+service authority. A revoked grant, a changed deadline or a passed `expiresAt`
+refuses the read with `credential-refused` before BReg is contacted. The run's
+`deadlineSeconds` of one day is a run cutoff; it never extends the shorter
+Casework approval.
+
+The scenarios cover a read after the virtual wait, an expired approval refused
+with `credential-refused`, a record the profile no longer shows
+(`product-not-found`), and an unavailable credential service
+(`credential-unavailable`). In the service, the Coordinator retries
+`credential-unavailable` on its own within the deadline, as
+[Recover safely](../../DEPLOYMENT.md#recover-safely) describes; the scenario
+stops at the first such answer. The scenarios use synthetic replies only, so
+they do not prove Casework approval, task-grant exchange or BReg access policy.
+
+For a deployment, the institution must supply these prerequisites:
+
+- BReg exposes a reviewed `approved-reader` profile that reads the collections
+  callers name in `collection`, and admits the token the exchange issues.
+- The token endpoint registers the `task-agent` client. It issues that client a
+  token for `urn:example:casework` with scope `casework:grants:assert`, and
+  exchanges a Casework task assertion for a token for
+  `urn:example:applications` with scope `records:get`.
+- Casework, at `taskAuthority.baseUrl`, holds the approved grant for the
+  registered agent subject `registered-agent-subject` and issues its task
+  assertions as `https://casework.local.example`.
+- Callers hold a Coordinator access token for the `approved-record-check` flow,
+  and an explicit operator policy grants inspection and recovery separately.
+
+The runtime template uses loopback endpoints and secret references only, and
+sets `clientAssertionAudience`, the audience of the client's signed assertion;
+without it, the token endpoint URL is used. Copy it outside the package and
+adapt its endpoints, PostgreSQL identity and roles, client, task authority and
+package pin. Follow [the deployment runbook](../../DEPLOYMENT.md) for
+installation and apply.

+# Bounded poll project
+
+Use this synthetic example when a run must check a source record a few times
+until the source decides, then hand control back to the caller. It reads one
+Base Registry Engine (BReg) application at three fixed times and finishes with
+the decision, or with `still-pending` after the third read. The workflow, pure
+functions, deterministic scenarios and runtime template form one complete
+project.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/bounded-poll --explain
+coordinatorctl test --project products/coordinator/examples/bounded-poll
+```
+
+The workflow graph is finite and acyclic, so the poll is unrolled into three
+rounds. Each round is a `wait-until` step, a `read-record` call and a `choose`
+step:
+
+1. `wait-1` waits until the input's `firstCheckAt`, `read-1` reads the
+   application and `check-1` calls `review_state` on the record.
+2. `wait-2` waits until one day after `firstCheckAt`, computed by `check_time`
+   with `add_seconds`, then `read-2` and `check-2` repeat the read and choice.
+3. `wait-3` waits until two days after `firstCheckAt`, then `read-3` and
+   `check-3` read and choose a last time.
+
+When the record's `domainData.reviewState` is `approved` or `rejected`, the run
+finishes with outcome `decided` and that value as `decision`. After three
+pending reads it finishes with outcome `still-pending` and no output. Each check
+happens at its time whether or not the record changed; BReg sends the run no
+signal. While the run waits, `coordinatorctl status` reports the next check
+time as `nextDueAt`. Once it finishes, the caller reads `outcome` and `output`
+from the same status and decides whether to start a new run later, with a new
+idempotency key.
+
+The scenarios cover a decision at the first read, a decision at the third read,
+three pending reads, a refused read that stops the run, and a late
+`firstCheckAt`. The run has a `deadlineSeconds` of seven days from admission,
+so the last check, two days after `firstCheckAt`, must fall inside it. When a
+wait ends at or after the deadline, the run expires instead of reading again;
+the
+`late-first-check-reaches-the-deadline` scenario shows that case.
+
+To change the number of checks or their spacing, add or remove a round, give its
+wait a later `check_time` argument, and keep the last wait inside
+`deadlineSeconds`. Each round is a separate read step, so `inspect` lists every
+read the run reached.
+
+For a deployment, the institution must supply these prerequisites:
+
+- BReg exposes a reviewed `review-reader` profile that reads the `applications`
+  collection, and its application records carry `reviewState` in
+  `domainData`.
+- The token endpoint registers the `application-reader` client for resource
+  `urn:example:applications` with scope `applications:read`, and BReg admits
+  that client to the `review-reader` profile.
+- Callers hold a Coordinator access token for the `bounded-poll` flow, and an
+  explicit operator policy grants inspection and recovery separately.
+
+The runtime template uses loopback endpoints and secret references only. Copy
+it outside the package and adapt its endpoints, PostgreSQL identity and roles,
+client and package pin. Follow [the deployment runbook](../../DEPLOYMENT.md)
+for installation and apply.

+# Typed decision followed by a governed action
+
+Use this synthetic example to test a decision, an explicit business threshold,
+and a separate Base Registry Engine (BReg) action. The model sees only the
+application summary. BReg receives the application identifier and still checks
+its own action metadata, profile, conditions, and current authority.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/decision-follow-up --explain
+coordinatorctl test --project products/coordinator/examples/decision-follow-up
+```
+
+The check validates the graph, script, scenarios, and runtime configuration without
+resolving the referenced keys or contacting a model. The tests cover a governed
+action, no action, low confidence, model refusal, product refusal, lost or
+malformed model replies, and a credential failure. The model-refusal case uses
+an OpenAI normalized reply
+to demonstrate the same authored policy with that binding. System One HTTP
+refusal instead stops the call; it cannot produce this per-question answer.
+A nonzero exit identifies the failed check or scenario; repair that case before
+packaging or activation.
+
+The example uses an illustrative confidence threshold of 0.8. Validate thresholds
+with labeled cases for your selected model and use case before enabling actions.
+Native confidence is a provider statistic, not a guarantee of correctness or an
+interchangeable measure between models. `needs-review` is a terminal return to
+the caller; it does not create a Casework task or acquire human approval.
+
+For a deployment, provide your BReg endpoint and an explicitly authorized
+`coordinator-actions` profile exposing a `request-information` action with
+`applicationId` and `reason` inputs. The action is a project declaration, not a
+built-in Coordinator operation. Configure the shared secret references and
+choose an available reviewed model. Inspect provider data retention and minimize
+the summary before activating a remote binding. This fixture's endpoints and
+identities do not configure a working institutional deployment.
+
+To use OpenAI Decisions, change the same logical binding to `openai-decisions`,
+its service root, and an available model name. The authored questions do not
+change. To use a System One compatible local service such as Ollama, select
+`system-one`, its numeric loopback root, an installed decision model, and
+explicit `authorization: {local: {}}`. Protocol fixtures prove the request and
+response shapes, not an actual installed model or service account.
+
+A successful answer is saved before branching. A later retry or restart reuses
+it. An uncertain evaluation has no proven receipt or safe replay contract:
+`retry-same` and reconciliation are refused. You can cancel and make a separately
+authorized new start, accepting possible additional model cost and a different
+answer. Neither cancellation nor a new start retracts provider processing.
+Cancellation remains visible as `cancelRequested: true` alongside the unknown
+outcome. After a restore, use the [recovery procedure](../../DEPLOYMENT.md#backup-and-restore)
+to abandon that cancelled evaluation without blocking unrelated work or replaying it.
+
+General JSON generation, images, asynchronous jobs, training, and model tool
+execution are not supported. No live provider call is part of the offline check.

+# Deferred appointment project
+
+Use this reviewed example for one current eligibility read, a durable wait, one
+approved appointment and a separate accepted notice. The workflow, pure
+functions, deterministic scenarios and runtime template form one complete
+project. Configure the owning product policies before sending real work.
+
+```sh
+coordinatorctl --runtime-config /absolute/path/runtime.yaml \
+  check --project products/coordinator/examples/deferred-appointment --explain
+coordinatorctl test --project products/coordinator/examples/deferred-appointment
+```
+
+The runtime template uses HTTPS reference endpoints and secret references only.
+Copy it outside the package and adapt its absolute paths, PostgreSQL identity and
+roles, OIDC issuer/audience, exact clients/scopes, task authority and package pin.
+Follow [the deployment runbook](../../DEPLOYMENT.md) for installation and apply.
+The institution must supply these prerequisites:
+
+- Base Registry Engine (BReg) exposes the reviewed `follow-up-reader` profile
+  and fields that the functions inspect for current eligibility and contact
+  details.
+- Scheduling publishes offering `application-review` at the approved location and anchored
+  windows. A catalogue identity reads metadata and availability. A separate
+  booking agent consumes an approved Casework deferred grant for the exact
+  service, location, actions and original deadline.
+- Casework exposes that approved grant to the registered booking agent and issues
+  fresh task assertions. Revocation, expiry, changed bounds or source invalidation
+  refuses booking; the workflow never falls back to standing service authority.
+- The booking agent's required `observationAuthorization` has the same token endpoint,
+  registered client and resource. Scheduling's original-key receipt API authorizes
+  its exact verified issuer/subject and returns only authoritative observation.
+  The observation scope grants no authority to create a new appointment.
+  Receipt recovery uses ordinary read credentials even after grant expiry or
+  revocation; it never requests another Casework assertion or task-token exchange.
+- Messaging permits sender profile `transactional`, template `appointment-confirmed`
+  version `1`, and locale `en` for the reviewed sender identity. Acceptance
+  and provider delivery remain distinct product observations.
+- Institutional producers hold an audience-bound Coordinator access token for
+  the `deferred-appointment` flow. An explicit operator policy grants inspection
+  and recovery separately.
+
+Input contains `applicationId`, `bookAfter`, `searchStart`, `searchEnd` and an
+approved `grant` with its `id` and original `expiresAt` Unix timestamp. Keep the
+search interval and booking time inside the grant's original bounds. Input carries
+no credentials. The mappings derive the product requests; they do not decide
+which scopes or identities the operator registered.
+
+Package the project and retain its idempotency key through response loss. Reconciliation
+uses the original booking or message key and owner. It cannot infer non-existence
+from an expired receipt or unavailable receiver. Runtime key rotation preserves
+registered identities; workflow edits cannot alter an admitted run's snapshot.

+# Delayed follow-up project
+
+Use this synthetic example when a run must wait until a set time, read the
+current Base Registry Engine (BReg) record, and send one notice through Registry
+Messaging only when the record still permits it. It is the starter that
+`coordinatorctl init` writes: the same four files, with the project id and the
+file secret root replaced. The workflow, pure functions, deterministic
+scenarios and runtime template form one complete project.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/delayed-follow-up --explain
+coordinatorctl test --project products/coordinator/examples/delayed-follow-up
+```
+
+The `due` step waits until the input's `sendAfter`. Then:
+
+1. `read-application` reads the application named by `applicationId` from the
+   `applications` collection.
+2. `permission` calls `notice_route` on the record. When
+   `domainData.noticeAllowed` is true the run continues to `notify`; otherwise
+   it finishes with outcome `no-current-permission` and no output.
+3. `notify` submits one message built by `notice_request`: sender profile
+   `transactional`, template `application-follow-up` version `1`, locale `en`,
+   the record's `domainData.email` as the destination, and the application
+   identifier as template data.
+4. `accepted` finishes with outcome `message-accepted` and the Messaging
+   `messageId`.
+
+The record is read after the wait, so the permission and contact details are
+the ones BReg holds at send time, not at admission. `message-accepted` means
+Messaging accepted the submission; provider delivery is a separate Messaging
+observation. The run's `deadlineSeconds` is 30 days from admission.
+
+The scenarios cover a notice accepted after the virtual wait, a permission
+withdrawn before the read, and four lost or unproven Messaging answers. After a
+lost response, `retry-same` resends the saved command and key, and `reconcile`
+reads the Messaging receipt for the original key; both cases finish with the
+accepted message. An expired receipt, or a refusal after a lost response,
+leaves the run `uncertain`, because neither proves that Messaging did not
+accept the first submission.
+
+For a deployment, the institution must supply these prerequisites:
+
+- BReg exposes a reviewed `follow-up-reader` profile that reads the
+  `applications` collection, including `noticeAllowed` and `email` in
+  `domainData`.
+- The token endpoint registers the `application-reader` client for resource
+  `urn:example:applications` with scope `applications:read`, and the
+  `case-system` client for resource `urn:example:messaging` with scope
+  `messaging:send`. BReg admits `application-reader` to the `follow-up-reader`
+  profile.
+- Messaging permits sender profile `transactional`, template
+  `application-follow-up` version `1` and locale `en` for the `case-system`
+  caller.
+- Callers hold a Coordinator access token for the `delayed-follow-up` flow,
+  and an explicit operator policy grants inspection and recovery separately.
+
+The runtime template uses loopback endpoints and secret references only. Copy
+it outside the package and adapt its endpoints, PostgreSQL identity and roles,
+clients and package pin. Follow [the deployment runbook](../../DEPLOYMENT.md)
+for installation and apply.

+# External directory project
+
+Use this synthetic example when a run needs one read from an HTTP service that
+is not a Registry Stack product, such as an office directory. The run sends one
+GET for the input's `district` and finishes with the first office identifier,
+with `no-directory-entry`, or with `directory-unavailable`. The workflow, pure
+functions, deterministic scenarios and runtime template form one complete
+project.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/external-directory --explain
+coordinatorctl test --project products/coordinator/examples/external-directory
+```
+
+The `lookup` step calls `external-get` on the logical `directory` connection.
+`lookup_request` supplies only the path `offices` and the query value
+`district`. The runtime's `externalHttpConnections.directory` fixes the base
+URL, the permitted path and query names, and the `responseSchema` that the
+reply `{status, body}` must match. A path or query name outside those lists is
+refused with `external-invalid-command`.
+
+The `result` step calls `office_route` on the validated reply:
+
+- Status 404, or status 200 with no items, finishes with `no-directory-entry`.
+- Status 200 with items finishes with `office-found` and the first item's `id`
+  as `officeId`.
+- A 429, 502, 503 or 504 on the last attempt finishes with
+  `directory-unavailable`.
+
+The schema permits 404, 429, 502, 503 and 504 with an empty body, so the
+workflow decides what they mean. A busy or failing gateway is retried first:
+the adapter reports a 429 as the retryable `external-rate-limited` and a 502,
+503 or 504, like a timeout or connection failure, as the retryable
+`external-unavailable`, and the Coordinator retries it on its own, as
+[Recover safely](../../DEPLOYMENT.md#recover-safely) describes. Only the tenth
+attempt hands the status to the workflow. Ten attempts with nine waits of at
+most the 300-second backoff cap, which a `Retry-After` never exceeds, take
+less than an hour, so the run's 3600-second deadline lets a directory that
+stays busy reach `directory-unavailable` instead of ending the run `expired`.
+A reply the schema does not permit, such as status 500, stops the run with
+`external-invalid-response` on its first attempt.
+
+The scenarios cover an office found, a 404, an empty result, each of the four
+busy or failing statuses on the last attempt, and a transport failure.
+Scenarios do not run the automatic retries: a 429, 502, 503 or 504 reply in a
+scenario stands for the final attempt, and the transport failure scenario
+stops at the first `external-unavailable` answer.
+
+The connection has no `authorization` block. It is a public read, and the
+Coordinator never sends the caller's token to the directory. To call a
+protected directory, add an ordinary service `authorization` with
+`tokenEndpoint`, `clientId`, `signingKeyRef`, `resource` and `scopes`;
+`taskAuthority` is not accepted here. Each attempt uses the defaults of 2000
+milliseconds and 65,536 response bytes, which `attemptTimeoutMilliseconds` and
+`maximumResponseBytes` may lower.
+
+For a deployment, the institution must supply these prerequisites:
+
+- The directory serves `GET offices?district=...` below its base URL with read
+  semantics. It answers 200 with a JSON body of the form
+  `{"items": [{"id": "..."}]}`, or 404 with an empty body. When it or a
+  gateway in front of it is busy or failing, it answers 429, 502, 503 or 504
+  with an empty body; the adapter reads that body only on the final attempt.
+- The endpoint uses HTTPS. Plain HTTP is accepted only on an explicit numeric
+  loopback address, as in this template.
+- Callers hold a Coordinator access token for the `external-directory` flow,
+  and an explicit operator policy grants inspection and recovery separately.
+
+The runtime template has no product connections, uses a loopback endpoint, and
+contains secret references only. Copy it outside the package and adapt its
+endpoint, response schema, PostgreSQL identity and roles, and package pin.
+Follow [the deployment runbook](../../DEPLOYMENT.md) for installation and apply.

+# Governed action follow-up project
+
+Use this synthetic example when a run must read a Base Registry Engine (BReg)
+record, invoke one governed BReg action when the record needs it, and then send
+a separate notice through Registry Messaging. The workflow, pure functions,
+deterministic scenarios and runtime template form one complete project.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/governed-action-follow-up --explain
+coordinatorctl test --project products/coordinator/examples/governed-action-follow-up
+```
+
+The run starts at once and has a `deadlineSeconds` of 300:
+
+1. `read-application` reads the application named by `applicationId` from the
+   `applications` collection.
+2. `needs-information` calls `information_route` on the record. When
+   `domainData.complete` is true the run finishes with outcome
+   `no-information-request-needed` and no output; otherwise it continues.
+3. `request-information` calls `invoke-breg-action` with action
+   `request-information` and two inputs: `applicationId`, and a `reason` built
+   from the record's `domainData.missingField`.
+4. `notify` submits one message with sender profile `transactional`, template
+   `information-requested` version `1` and locale `en` to the record's
+   `domainData.email`, carrying the application identifier the action returned.
+5. `accepted` finishes with outcome `action-and-notice-accepted`, the action's
+   `actionApplicationId` and the Messaging `messageId`.
+
+BReg decides whether the action runs. It checks its action metadata, the
+`workflow-actions` profile, the action's conditions and current authority; the
+action name in `functions.rhai` grants nothing. `invoke-breg-action` uses the
+connection's standing service identity and accepts no Casework grant, so this
+connection has no `taskAuthority`.
+
+After a lost action response the run is `uncertain`. `retry-same` resends the
+saved prepared command with its original key. Reconciliation is refused for
+this step: BReg has no read-only action receipt, and a record read does not
+prove that the action succeeded. When Messaging refuses the notice after BReg
+accepted the action, the run ends `refused` and the action stays accepted;
+cancellation does not roll it back.
+
+The scenarios cover an accepted action and notice, a complete application that
+needs no action, a refused action, a lost action response left unresolved, a
+lost action response recovered with `retry-same`, and a notice refused after an
+accepted action. They use synthetic replies only, so they do not prove BReg
+action policy, target preconditions, remote acceptance or provider delivery.
+
+For a deployment, the institution must supply these prerequisites:
+
+- BReg exposes a reviewed `workflow-actions` profile that reads the
+  `applications` collection, including `complete`, `missingField` and `email`
+  in `domainData`, and permits the immediate `request-information` action with
+  `applicationId` and `reason` inputs.
+- The token endpoint registers the `application-agent` client for resource
+  `urn:example:applications` with scopes `applications:read` and
+  `applications:act`, and the `case-system` client for resource
+  `urn:example:messaging` with scope `messaging:send`. BReg admits
+  `application-agent` to the `workflow-actions` profile.
+- Messaging permits sender profile `transactional`, template
+  `information-requested` version `1` and locale `en` for the `case-system`
+  caller.
+- Callers hold a Coordinator access token for the `governed-action-follow-up`
+  flow, and an explicit operator policy grants inspection and recovery
+  separately.
+
+The runtime template uses loopback endpoints and secret references only. Copy
+it outside the package and adapt its endpoints, PostgreSQL identity and roles,
+clients and package pin. Follow [the deployment runbook](../../DEPLOYMENT.md)
+for installation and apply.

+# Coordinator operation reference
+
+Each catalog operation has an input contract, the type its adapter decodes, and an output contract, the type its adapter returns as the step output. A mapping that feeds a call must produce a value its input contract accepts; a reference into a call step's output must name a path its output contract declares.

Subject: [PATCH 16/37] feat(coordinator): wait for a Casework review result

A casework connection names one review producer and its profile. A run
submits a review request through the Casework client, recovers an
accepted request under the same idempotency key, and counts a cancel of
a request that already ended as done. Both operations carry contracts
generated from the review protocol types.

A wait-for step then waits for that request's result. Check refuses a
request that does not precede the wait on every route, a timeout that is
not shorter than the run deadline, and a read of the result on the
timeout route, and holds the result to a generated review-result event
contract. Casework's completion event reaches the completion receiver,
which matches the sender's bearer token and recipient binding in
constant time and brings the next result read forward; the event never
settles the wait by itself. Every read checks the result against the
accepted request before the run continues with it.

Without an event, the run reads the result every resultCheckSeconds of
its connection while the review is open, and once more at the timeout.
A busy or unreachable Casework leaves the wait open: the next read
follows Retry-After within its bounds, or waits the five-minute retry
ceiling. When no result arrives in time, the run continues at the
timeout route. Retention and attested recovery end the wait rows, and
the configuration formats classify the omitted metrics bind and
assertion issuers as closed.

Scenarios can state the review result a wait receives or its timeout.
The reviewed-notice example submits an application to review, sends a
Messaging notice on approval, finishes differently on rejection, and
withdraws the request after fourteen days, routing on the cancel outcome
so that a decision recorded just before the withdrawal is kept.

+
+```yaml
+connections:
+  review:
+    product: casework
+    baseUrl: https://casework.example.org
+    profile: coordinator-producer

+
+`completion` and `resultCheckSeconds` are accepted only on a Casework connection, and changing them does not change a run's binding.
+
+The `submit-review-request` input names the review `kind`, the `subject` record with its source, type, id, version and digest, the `context` a reviewer sees, and a `requesterReference`.
+Its output is Casework's acceptance: `requestId`, `subject`, `policy` and `submissionDigest`.
+The `cancel-review-request` input passes that acceptance as `request` with a `reason`; its output is `outcome`, `cancelled` or `already-terminal`, with the review's terminal `result`.
+Route on `/outcome`: only `cancelled` means the cancellation ended the review, and `already-terminal` carries the decision a reviewer recorded first.
+Both are mutations without a read-only receipt: `retry-same` resends the saved request with its original key, and `reconcile` reports `reconciliation-unavailable`.
+
+A `wait-for` step waits for the result of a submitted request:
+
+```yaml
+await-review:
+  type: wait-for
+  event: {type: review-result, request: submit-review}
+  timeoutSeconds: 1209600
+  next: decide
+  onTimeout: withdraw
+```
+
+`timeoutSeconds` accepts 1 to 31,536,000 and must be shorter than `deadlineSeconds`.
+The step reads the result with the producer identity when it starts, every `resultCheckSeconds` while the review is open, and once more at the timeout.
+A read that Casework answers as busy, or that cannot reach Casework, leaves the wait open: the next read follows Casework's `Retry-After`, no sooner than 30 seconds and no later than `resultCheckSeconds`, and without one comes five minutes later, or after `resultCheckSeconds` when that is shorter, so an outage shorter than the timeout does not fail the run.
+A settled result continues at `next` as the step's output; a `choose` reads its `/status`: `approved`, `rejected`, `changes-requested`, `answered`, `cancelled` or `superseded`.
+A result for another request, subject, policy or submission digest fails the run with `invalid-response`.
+An unknown request fails it with `review-request-unknown` and an expired result with `review-result-expired`.
+The timeout continues at `onTimeout`, or fails the run with `wait-timed-out`; a result found by the read at the timeout wins.
+A deadline that comes first ends the run `expired` with `deadline-reached`.
+
+Casework supersedes a request still under review when the same producer submits another for the same subject record, of any version, and the same kind.
+The waiting run then reads `superseded`, so choose on it wherever two runs can submit for one record.
+
+With `completion` configured, Casework posts each completion event to `POST /v1/review-completions` on the service listener.
+The receiver refuses any sender without the configured bearer token and recipient binding, and answers every authentic event with 204 whether or not a run waits on its request.
+The event is a wake-up only: it brings the next read forward to no sooner than 30 seconds after the previous one, and the read decides the result.
+No event starts a run.
+
+The maintained [reviewed notice project](https://github.com/registrystack/registry-stack/tree/main/products/coordinator/examples/reviewed-notice) submits a review, waits up to fourteen days, sends a notice on approval and withdraws the request on timeout.
+Its scenarios state each wait's result or timeout with `waits`; they do not prove Casework review policy or completion delivery.

+
+The Coordinator then accepts Casework's completion events at

+starts at admission would reach the run deadline first and expire instead of
+taking its timeout route. At run time the deadline still wins, so a wait that
+starts late in the run expires it with `deadline-reached` when the deadline
+comes before the timeout.

+completion event for the request brings the next read forward, to no sooner
+than 30 seconds after the previous one, however many events arrive. The event
+carries no result and never settles the wait by itself; when it does not
+arrive, the result checks still find the result. A completed result continues
+the run at `next` with the result as the step's output, so a `choose` reads its
+`/status`: `approved`, `rejected`, `changes-requested`, `answered`, `cancelled`
+or `superseded`. The result must belong to the accepted request, with the same
+request, subject, policy and submission digest; any other result fails the run
+with `invalid-response`. A request Casework does not know fails the run with
+`review-request-unknown`, and a result Casework no longer holds with
+`review-result-expired`. When the timeout passes without a result, the run
+continues at `onTimeout`, or fails with `wait-timed-out` when the step has
+none. A step reached through `onTimeout` cannot read the wait's output, and a
+result found by the read at the timeout wins over the timeout.

+Casework supersedes a review request still under review when the same producer
+submits another one for the same subject record, of any version, and the same

+# Reviewed notice project
+
+Use this synthetic example when a run must hand an application to human review
+in Registry Casework, wait for the decision, and send a notice through Registry
+Messaging only when the review approves it. The workflow, pure functions,
+deterministic scenarios and runtime template form one complete project.
+
+From the repository root, run the offline authoring commands:
+
+```sh
+coordinatorctl check --project products/coordinator/examples/reviewed-notice --explain
+coordinatorctl test --project products/coordinator/examples/reviewed-notice
+```
+
+The run starts at once and has a `deadlineSeconds` of 2592000 (thirty days):
+
+1. `submit-review` submits one review request of kind `application-review` to
+   Casework as the review producer. The request names the application version
+   and digest under review and submits the only context a reviewer sees, the
+   application identifier and version, so Casework needs no source adapter.
+2. `await-review` waits for the result of that request for at most fourteen
+   days (`timeoutSeconds: 1209600`). Casework's completion event wakes the
+   run; the event carries no result and only prompts a read. The Coordinator
+   reads the result with the producer identity when the wait starts, on each
+   wake and every `resultCheckSeconds` (900 in the runtime template) as a
+   fallback, and keeps waiting while the review is open.
+3. `decide` chooses on the result's `status`. `approved` continues to
+   `notify`, `rejected` finishes with outcome `rejected`, and every other
+   settled status (`changes-requested`, `answered`, `cancelled` and
+   `superseded`) finishes with outcome `not-decided` and that status.
+4. `notify` submits one message with sender profile `transactional`, template
+   `application-approved` version `1` and locale `en` to the input `email`. The
+   message cites the review result by `resultId` and repeats none of its
+   content.
+5. `notice-sent` finishes with the Messaging `messageId` and the `resultId`.
+
+When the fourteen days pass without a settled result, `withdraw` cancels the
+review request in Casework and `confirm-withdrawal` chooses on the
+cancellation's `/outcome`. `cancelled` finishes with outcome `withdrawn` and
+the `resultId` Casework recorded for the cancellation. A reviewer can decide in
+the moment before the cancellation reaches Casework: the cancellation then
+reports `already-terminal` with that decision, and the run finishes with
+outcome `decided-late`, the decision's `status` and its `resultId`. The run
+sends no notice for a late decision; an operator reads the outcome and follows
+up in Casework. Any workflow that withdraws a review routes on the cancel
+step's `/outcome` the same way, since only `cancelled` means the withdrawal
+ended the review. A result that settles in the final read at the timeout wins
+over the timeout and continues at `decide`.
+
+The result a read returns must belong to the accepted request: the same
+request, subject, policy and submission digest. Any other result fails the run
+with `invalid-response`. An unknown request fails with
+`review-request-unknown` and an expired result with `review-result-expired`.
+Casework supersedes a request that is still under review when the same
+producer submits another for the same application and kind, whatever its
+version. Every run of this flow submits as producer `coordinator`, so a second
+run for the same application supersedes the first: the first run reads
+`superseded` and finishes `not-decided`, and the second run waits for the
+replacement review.
+
+The scenarios cover an approved review and its notice, a rejected review with
+no notice, a request for changes that is not a decision, a withdrawal after
+fourteen days without a decision, a decision recorded shortly before the
+withdrawal that finishes `decided-late`, and a notice refused after an
+approval. They use synthetic replies
+and review results only, so they do not prove Casework review policy, reviewer
+authority, completion delivery, Messaging policy or provider delivery.
+
+For a deployment, the institution must supply these prerequisites:
+
+- Casework declares review kind `application-review` version `1` with
+  `purpose: approval`, `contextStrategy: submitted` and a `displaySchema` that
+  accepts `applicationId` and `applicationVersion`. Its rejection and
+  change-request outcomes are Casework policy; the workflow reads only the
+  settled `status`.
+- Casework declares review producer `coordinator` for kind
+  `application-review` and source namespace `applications`, with the issuer and
+  subject of the Coordinator's Casework client and a `completion` block whose
+  `recipientBinding` is `coordinator-v1`.
+- Casework's runtime configuration lists that producer's completion
+  destination under `reviewCompletionDestinations`. Its `url` is the
+  Coordinator's `/v1/review-completions` route on the main listener and its
+  `bearerTokenRef` names the same secret as the Coordinator's
+  `completion.bearerTokenRef`. The Coordinator accepts only an
+  `Authorization: Bearer` header, so do not configure a custom header.
+- The token endpoint registers the `coordinator-review-producer` client for
+  resource `urn:example:casework` with scope `casework:review`, and the
+  `coordinator-notices` client for resource `urn:example:messaging` with scope
+  `messaging:send`. Casework admits the producer client to its
+  `coordinator-producer` profile.
+- Messaging permits sender profile `transactional`, template
+  `application-approved` version `1` and locale `en` for the notices caller.
+- Callers hold a Coordinator access token for the `reviewed-notice` flow, and
+  an explicit operator policy grants inspection and recovery separately.
+
+The runtime template uses HTTPS reference endpoints and secret references only.
+Copy it outside the package and adapt its endpoints, PostgreSQL identity and
+roles, clients, completion secret and package pin. Follow
+[the deployment runbook](../../DEPLOYMENT.md) for installation and apply.

Subject: [PATCH 17/37] feat(coordinator-client): add the bounded Coordinator
 client with Node.js and Python bindings

Applications start, list, read, inspect, reconcile, retry and cancel
Coordinator runs through the maintained client instead of hand-built
HTTP. Admission takes a caller-chosen key and {flow, input}; a start's
identity commits to the caller, the flow and the key, and only an
admission whose outcome is unknown is resent, under the same key. The
list, retry-same and cancel routes take no idempotency key, so the client
sends each exactly once and reports an unknown outcome instead of
resending; the list limit and the reason bound are refused before
sending. Operator routes stay with coordinatorctl.

flow-absent on start and run-absent for a run of a flow outside the
caller's policy surface as problems with the outcome known and are never
resent. The status DTOs refuse unknown fields and carry the nullable
failurePath beside failureCode; the DTO contract test compares each
schema's property set with its fixture, so a property the runtime adds
must reach the client in the same change.

The Rust facade exposes the client as registry_stack_client::coordinator;
the napi-rs and PyO3 bindings feed the unified Node.js and Python
packages.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Registry Coordinator Node binding
+
+This internal napi-rs binding is assembled into the `coordinator` namespace of
+`@registrystack/client`.
+
+Each operation accepts the bearer token for that call. `start` also takes the
+caller's idempotency key and exact input document. The binding never acquires a
+token or invents a key. `start` resends an admission whose outcome is unknown,
+identically and under the caller's same key, at most `maxMutationRetries` times
+(default 2, at most 2, 0 disables); a 4xx refusal is never resent. A key is
+scoped to the caller and the flow, so the same key under two flows starts two
+runs, and an allowed flow the deployment does not serve is refused with 404
+`flow-absent`, a known outcome never resent. `list`,
+`status`, `inspect`, `reconcile`, `retrySame`, and `cancel` send exactly one
+request. `reconcile` reads the receipt for the original operation and updates
+recovery state; it never resubmits that operation. `retrySame` and `cancel`
+take no idempotency key, so after an unknown outcome read the run before
+asking again. Operator routes are not part of this binding; `coordinatorctl`
+owns them.
+
+Configuration, request documents, UUIDs, and JavaScript integer bounds are
+checked before I/O. Errors expose a fixed safe message and the closed failure
+category. Coordinator problem codes remain strings because they are authored
+by the Coordinator contract. Response messages, credentials, request bodies,
+and transport chains are not copied into errors.

+# Registry Coordinator Python binding
+
+This internal PyO3 binding is not published separately. Its namespace and
+native extension are assembled into the `coordinator` namespace of the public
+`registry-stack-client` wheel. Built on its own, it is used like this:
+
+```python
+import registry_coordinator_client as coordinator
+
+client = coordinator.CoordinatorClient("https://coordinator.example.invalid/")
+started = client.start(
+    token,
+    "nursing-notice-2026-10-10-0001",
+    {"flow": "nursing-notice", "input": {"requestId": "one"}},
+)
+run_id = started["value"]["runId"]
+status = client.status(token, run_id)
+inspection = client.inspect(token, run_id)
+recovered = client.reconcile(token, run_id, "operator-ticket-4821")
+latest = client.list(token, 20)
+retried = client.retry_same(token, run_id, "operator-ticket-4822")
+cancelled = client.cancel(token, run_id, "operator-ticket-4823")
+```
+
+The client keeps service configuration, but never a bearer token. Supply it
+explicitly on each call. The binding never acquires a token and never invents
+an idempotency key. `start` requires the key chosen by the caller, 1 to 256
+visible ASCII characters, and a flow identifier of up to 64 letters, digits,
+hyphens, and underscores. The binding refuses any other key, flow, recovery
+reason, list limit outside 1 to 100, or run identifier before a request is
+sent. Run identifiers are lowercase hyphenated UUIDs. Results use the
+canonical Rust client's camel-case wire DTOs inside a `{"kind": "complete", "value": ...}` envelope.
+Coordinator defines no trace field, so there is no trace identifier.
+
+Configuration members are keyword arguments: `base_url` (required),
+`request_timeout_seconds`, `connect_timeout_seconds`,
+`max_response_bytes`, `user_agent`, `trusted_root_certificates`, and
+`max_mutation_retries`. Timeouts are seconds, as a finite non-negative `int` or `float`; the response
+bound is an `int`. A `bool` is not a number here. An unknown keyword is a Python `TypeError`.
+
+`CoordinatorClientError` preserves the status and the Coordinator's open
+problem code, and never carries the server's prose, a token, a key, a URL, or a
+request body. Its `kind` is one of `configuration`, `invalid-request`,
+`transport`, `problem`, or `protocol`; `protocol_failure` is one of
+`header-bounds`, `media-type`, `body`, `problem`, `status`, or `protocol`.
+
+The only resend is the Rust client's bounded same-key retry of `start`. An
+admission whose outcome is unknown (a timeout or broken exchange after it was
+sent, an unusable answer, or a 5xx) is resent identically under the same key up
+to `max_mutation_retries` times: 0 to 2, default 2, and 0 sends it once. A 4xx
+answer is never resent. `list`, `status`, `inspect`, `reconcile`,
+`retry_same`, and `cancel` send exactly one request; `retry_same` and `cancel`
+take no idempotency key, so after an unknown outcome read the run before
+asking again. When the returned `CoordinatorClientError` still reports
+`outcome_unknown`, the run may have been admitted: recover by sending `start`
+again with the same service identity, key, and input, because a new key can
+create another run. A key is scoped to the caller and the flow, so the same key
+under two flows starts two runs, and an allowed flow the deployment does not
+serve is refused with 404 `flow-absent`, a known outcome never resent.
+`outcome_unknown` is false for a configuration or request
+defect, a connection never established, and every 4xx refusal.
+
+`reconcile` observes the original supported product receipt from the runtime's
+saved command. It never resubmits it. A missing or expired receipt remains
+uncertain. `cancel` never undoes a product effect. Operator routes are not part
+of this binding; `coordinatorctl` owns them.
+
+This crate is private and does not publish a standalone Python distribution.

+# Registry Coordinator client
+
+A bounded server-side client for Registry Coordinator's HTTP contract. The
+public Rust facade exposes it as `registry_stack_client::coordinator`; the
+public Node.js and Python packages expose it as their `coordinator`
+namespace. Browser apps call their own authorized server routes.
+
+The operations are `start`, `list`, `status`, `inspect`, `reconcile`,
+`retry_same`, and `cancel`. The operator routes (doctor, holds, execution
+recovery and retention) are not part of this client; `coordinatorctl` owns them.
+Admission requires a caller-chosen idempotency key and `{flow, input}`. HTTP
+200 confirms admission and returns the run's current status. The runtime
+answers the same run again for the same caller, flow, key and input, and
+refuses the same key with a different input. A key is scoped to the caller and
+the flow, so the same key under two flows starts two runs, and an allowed flow
+the deployment does not serve is refused with 404 `flow-absent`, a known
+outcome the client never resends. When an admission's outcome is
+unknown, after a timeout or broken exchange or on a 5xx answer, the client
+resends the identical request under the same key, at most
+`with_max_mutation_retries` times (2 by default, at most 2, 0 disables it).
+It never resends after a 4xx status line. An error that still leaves the
+outcome unknown may have admitted a run: the caller retains the exact key,
+flow, input and service identity in durable state before dispatch and
+recovers under that same identity. Changing the key or the verified
+issuer/subject can create another run. `list`, `status`, `inspect`,
+`reconcile`, `retry_same` and `cancel` send exactly once. `retry_same` and
+`cancel` take no idempotency key, so the client never resends them: after an
+error that leaves the outcome unknown, read the run before asking again.
+`list` takes a limit from 1 to 100, refused before sending, and returns the
+latest runs the caller may read, newest admission first, without a cursor.
+
+Status is protected by current Coordinator policy and ownership. A run started
+by a backend is owned by that backend, even when its input mentions a citizen's
+record. Applications must independently authorize source-record access and use
+their explicit record-to-run correlation before displaying selected progress.
+
+`reconcile`, `retry_same` and `cancel` take a reason of 1 to 256 bytes without
+control characters, refused before sending. `reconcile` observes the original
+supported product receipt from the runtime's saved command. It does not
+resubmit a notice. A missing or expired receipt remains uncertain. A Messaging
+acceptance is never proof of provider delivery. `retry_same` schedules the
+saved command again, unchanged, only when the run's inspection allows it.
+`cancel` stops further progression and never undoes a product effect.
+
+Configuration validates a fixed HTTPS endpoint, or an explicit loopback HTTP
+endpoint for local development. Deployment prefixes are preserved. Shared
+transport disables redirects and ambient proxies; body and header limits apply
+to successes and failures. The client validates Coordinator's JSON problem
+shape, discards remote message text, and reports closed error categories with
+the answered status and the product's code. It does not invent an RFC 9457 or
+trace contract.
+
+Run `cargo test --locked -p registry-coordinator-client` and
+`cargo clippy --locked -p registry-coordinator-client --all-targets -- -D warnings`.
+HTTP tests bind disposable loopback sockets. They verify transport behavior,
+not product authorization.

+//! Bounded server-side Coordinator admissions, progress and original-receipt recovery.
+//!
+//! `list`, `status`, `inspect`, `reconcile`, `retry_same` and `cancel` send
+//! exactly one request; `retry_same` and `cancel` take no idempotency key, so
+//! the client never resends them. `start` resends an admission whose outcome
+//! is unknown under the caller's same key and body, at most
+//! `CoordinatorClientConfig::with_max_mutation_retries` times. The caller
+//! chooses the key and, after an error whose outcome is unknown, must retain
+//! the same verified issuer, subject, client, flow, input and key to recover.
+//! A service-owned run never becomes citizen-owned because its input names a
+//! citizen's record. Authorize the source record independently before
+//! disclosing an application-level correlation.
+//! Reconciliation observes the original supported product receipt; it never
+//! retries or replaces the product command. The operator routes (doctor,
+//! holds, execution recovery and retention) are not part of this client;
+//! `coordinatorctl` owns them.
+//!
+//! Coordinator's product-owned problem is JSON `{code,message,suggestedAction}`,
+//! not an RFC 9457 document. The client discards server prose and has no invented
+//! trace requirement. Redirects and ambient proxies are disabled by the shared
+//! transport, and JSON/header/body bounds are enforced on every response.

Subject: [PATCH 19/37] ci: gate Coordinator dependency direction and its
 client bindings

The Coordinator gate refuses, on the whole forward closure, a runtime that
reaches anything but product clients, cores, registry-record, and platform
crates, a client that reaches the runtime, and any crate outside the facade
and CLI reference tooling that depends on a Coordinator crate. The
Casework and Scheduling gates refuse the Coordinator from their side, and
root CI runs the gate on every Rust change and builds and tests the
Coordinator bindings with the others.

+product's runtime, adopter tooling, supporting service or binding. Its client
+reaches the runtime over the public HTTP contract only. No crate outside the
+Coordinator depends on a Coordinator crate unless it is named below.

+Edges are read with every feature enabled and on every target. A package's own

From 728b66ff9b6682ea8a7f11d1a5cebef7ee54db25 Mon Sep 17 00:00:00 2001
From: Jeremi Joslin <jeremi@joslin.fr>
Date: Mon, 12 Oct 2026 04:38:21 +0700
Subject: [PATCH 20/37] build(release): carry Coordinator in the unified
 clients from v0.41.0

The unified Node.js and Python facades carry the coordinator namespace,
and COORDINATOR_CLIENT_FIRST_RELEASE names v0.41.0 as the first release
that publishes it, the same way the Scheduling client joins at v0.40.0.
The release workflows select the Coordinator bindings from the roster,
the assemblers refuse an earlier version unless --include-coordinator
asks for local integration, and the client validators refuse a package
whose coordinator namespace does not match its version.

Signed-off-by: Jeremi Joslin <jeremi@joslin.fr>

Subject: [PATCH 21/37] docs: route Coordinator work and state what it may
 compose

Root AGENTS.md describes the Coordinator as explicitly started, finite,
reviewed workflows separated by waits that sequence product calls for the
caller who started the run, not as the way products connect, and
replaces the rule that runtimes may not compose with one that names how
they may: only through public product clients under a dependency gate.
The Coordinator guide records what it owns, what it never owns, and how
to verify a change. CLIENTS.md, the README, DEPLOYMENT.md,
PRODUCT-CONTRACT.md and the site configuration reference name the
maintained client.

+
+This directory owns the Coordinator deployment contract, generated schemas and
+API description, authored examples, and product-local verification scripts.
+Read the workspace `AGENTS.md`, this file, and `README.md` before changing the
+product.
+
+The Coordinator owns its finite, reviewed workflow packages, the durable run
+state and prepared commands it keeps in its own PostgreSQL database, its
+waits, and its audit journal. It never owns product authority, product data,
+eligibility, or capacity: each external effect belongs to the product that
+receives the call, which decides it under its own authorization.
+
+- Reach a product only over its public HTTP contract, through its maintained
+  Rust client. The runtime may depend on product clients, product cores,
+  `registry-record`, and `registry-platform-*`; never on a product runtime,
+  adopter tooling, a supporting service, or a language binding. Never write
+  to another product's database. Tests compose with another product the same
+  way, through its built executable and public HTTP contract, never through a
+  runtime dev-dependency.
+- The Coordinator inherits no authorization. A caller allowed to start a run
+  is not thereby allowed the effects its flow requests: every product decides
+  each call it receives under its own policy, and a wait never renews an
+  approval or creates downstream authority. A run belongs to the caller that
+  started it, and status and inspection follow that ownership and operator
+  policy. Status, inspection, and every run action also check the run's own
+  flow: a run of a flow the caller's policy does not list reads as
+  `run.not-visible`, and `list` leaves it out.
+- A run waits either until an instant or for a Casework review result, and
+  the completion event only brings the next result read forward. A run starts
+  only from an explicit caller request, never from a product event. Describe
+  the Coordinator as running reviewed sequences of product calls across those
+  waits, never as the way products connect to one another, until event-started
+  runs ship.
+- No product crate depends on a Coordinator crate. The only allowed dependents
+  are `registry-stack-client`, on `registry-coordinator-client`, and
+  `registry-cli-docs`, on `registry-coordinator` for the published CLI
+  reference. Adding a dependent, or a Coordinator crate, means naming its rule
+  in the gate in the same change. The Casework, Scheduling, and Messaging
+  gates also refuse the Coordinator from their side.
+- `registry-coordinator-client` reaches only `registry-platform-*` and never
+  the runtime. Its Node.js and Python bindings add no Coordinator semantics;
+  follow `crates/CLIENTS.md` when changing the client surface.
+- `scripts/check_dependency_direction.py` enforces both directions on the
+  whole forward closure with every feature enabled. A package's own
+  dev-dependencies count; those of a crate it reaches do not, since Cargo never
+  builds them into it. Run the gate and its tests after any dependency change.
+- Treat everything under `generated/` as generated output. The schemas come
+  from the generators `scripts/check-schemas.sh` runs, and the OpenAPI
+  document from `coordinatorctl openapi`; that script fails when either
+  drifts, and `README.md` gives the commands.
+- Changes to authentication, authorization, audit, data minimization,
+  retention, or recovery are security-sensitive and need explicit review
+  notes.
+- PostgreSQL verification requires disposable databases and the
+  `postgres-test` feature. A test binary that skips because its database URL
+  is absent is not database verification.

Subject: [PATCH 22/37] feat(coordinator)!: answer errors as problem documents

Coordinator refusals now answer as RFC 9457 problem documents, the
shape Casework, Messaging, and Scheduling already answer, so a caller
handles every Registry Stack product's errors the same way.

The runtime holds a closed vocabulary of 40 family.reason codes, each
with one status, title, and detail, exported by the problem-catalog
example and registered in the identifier catalog under
registry-coordinator. Internal error codes map to it at the HTTP
boundary only; edge rejections (unknown route, wrong method, oversized
or mistyped body, malformed JSON) answer from the same vocabulary, and
a missing run and a run the caller may not see both answer
run.not-visible. A problem carries type, title, status, detail, code,
and traceId, never a submitted value; the former suggestedAction
member is dropped, and coordinatorctl keeps its own fix advice.
review-completions keeps its 204 and refuses with problems. The
OpenAPI document lists the problems each operation can answer.

The Rust client accepts a refusal only as an exact problem document
whose status, trace, code grammar, and type URI agree, and the Node.js
and Python bindings pass its code through unchanged.

Security review notes: this changes the refusal surface of every
authenticated route. Problems echo no request value, title and detail
are fixed per code, 401 keeps WWW-Authenticate: Bearer, every problem
keeps cache-control: no-store, and run visibility stays non-oracular:
an absent run and another caller's run answer the same document apart
from the per-request traceId.

+
+//! The closed problem vocabulary of Registry Coordinator.
+//!
+//! Every refusal the HTTP service answers is an RFC 9457 problem document
+//! whose `code` is one of these values and whose `type` is that code under
+//! [`PROBLEM_TYPE_BASE`], with each `.` read as a path separator. The
+//! vocabulary is closed on purpose: a caller can enumerate every problem this
+//! product can ever return, and a problem code outside this list is a defect,
+//! not a compatibility event. A code joins the list in the same change that
+//! first returns it.
+//!
+//! The runtime raises its own internal error codes, which `coordinatorctl`
+//! reports and the service records; [`for_error`] is the one place that turns
+//! an internal code into the public problem the service answers with. Several
+//! internal spellings collapse into one public code where a caller has nothing
+//! different to do about them.
+//!
+//! `authorization.refused` is deliberately absent: it is an audit reason
+//! family used by other Registry Stack products, and audit reasons and problem
+//! codes must not be conflated. The authorization refusals callers see here
+//! are `authentication.refused` and `operation.not-authorized`.
+//!
+//! `run.not-visible` answers every run the caller may not see, whether or not
+//! the run exists, and whether its flow lies outside the caller's policy or it
+//! belongs to another caller, so the run routes are never an existence
+//! oracle. `flow.not-served` is answered only after the caller's policy has
+//! already admitted a start of the named flow, so it tells a caller nothing
+//! about flows outside its own policy.
+//!
+//! The `request.*` family carries the request-edge rejections (a route that
+//! does not exist, a method the route refuses, a body too large or not JSON)
+//! and the bounded-field refusals of the request itself, under this product's
+//! own prefix exactly as Casework, Scheduling and Messaging do: no shared
+//! platform problem prefix exists in the Registry Stack catalog.
+//!
+//! `audit.response-unavailable` is the one 503 after which the operation may
+//! already have completed; a caller inspects the run before repeating it.

Subject: [PATCH 23/37] build(release): ship Coordinator binaries and image
 from v0.41

Registry Coordinator joins the release roster at v0.41.0 through
COORDINATOR_FIRST_RELEASE, used the way the Messaging constant is. The
core shard builds the Linux amd64 coordinator and coordinatorctl, the
candidate and rehearsal smoke both and run coordinatorctl init and check,
and the coordinator image carries coordinatorctl for the operator
commands its deployment runbook runs against the runtime file.

Nightlies from that base version record roster profile v2.1, the frozen
v2.0 inventory plus Coordinator, so earlier v2.0 manifests stay readable.

The image is deny-listed as a public package only. coordinator-candidate
and the advisory baseline follow the GHCR bootstrap and a reviewed
advisory-evidence rehearsal, as for any new image.

+# Registry Coordinator changelog
+
+## Unreleased
+
+First release of Registry Coordinator.
+
+- The `coordinator` runtime executes finite, acyclic YAML workflows with
+  declarative mappings and bounded pure Rhai functions, across durable waits,
+  service outages and worker restarts. PostgreSQL stores encrypted progress
+  and prepared commands, the operation inventory is fixed, and receiving
+  products retain authorization and ownership of every external effect. One
+  deployment serves up to sixteen flows, one pinned package per flow.
+- `coordinatorctl` authors and checks projects (`init`, `check`, `explain`,
+  `test`, `package`), operates a deployment from its runtime file (`plan`,
+  `apply`, `deployment-status`), and checks a running service (`doctor`).
+- Every refusal of the HTTP API is an RFC 9457 `application/problem+json`
+  document whose `type` sits under
+  `https://id.registrystack.org/problems/registry-coordinator/`. The
+  generated OpenAPI document lists the codes each operation can answer.
+- The Coordinator client covers `start`, `list`, `status`, `inspect`,
+  `reconcile`, `retry_same` and `cancel` as
+  `registry_stack_client::coordinator` in Rust and the `coordinator`
+  namespace of the unified Node.js and Python clients.
+- `submit-review-request` and `cancel-review-request` hand work to Casework
+  human review as a review producer, and a `wait-for` step on a
+  `review-result` event waits for the reviewer's result.
+- Add Linux amd64 `coordinator` and `coordinatorctl` binaries and a Docker
+  image that carries both, from v0.41.0.

Subject: [PATCH 25/37] docs(site): publish Registry Coordinator docs in the
 latest docset

Add the Coordinator overview, flow authoring, deployment, and API pages,
render its committed OpenAPI contract, gate every Coordinator page and
shared-page mention to docsets that ship it, and link the existing
configuration reference into the new pages.

+serves it. Endpoints, credentials, caller policies, and keys never enter the package;
+[Deploy Registry Coordinator](../../operate/coordinator/) covers them.

+```sh
+cargo build --locked --release -p registry-coordinator --bins
+mkdir -p "$HOME/.local/bin"
+install -m 755 target/release/coordinator target/release/coordinatorctl "$HOME/.local/bin/"
+export PATH="$HOME/.local/bin:$PATH"
+```
+
+On macOS arm64, each binary has to carry the FIPS library the build links, so copying the executable
+alone loses a runtime dependency. Follow the macOS steps in the
+[deployment runbook](https://github.com/registrystack/registry-stack/blob/main/products/coordinator/DEPLOYMENT.md#install-and-package),
+which package each binary with its library and install the result.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Install and package. */}
+
+The authoring commands `init`, `check`, `explain`, `test`, and `package` work offline: they read no
+credential and send no request. Each prints readable text by default, or one JSON report of kind
+`CoordinatorCtlReport` with `--format json`, carrying `ok`, `command`, `status`, and a
+`diagnostics` array for a refusal. A command exits 0 when it accepts its input, 1 when it refuses
+it, 2 on a usage error, and 3 when a resource it needs is unavailable. Run
+`coordinatorctl <command> --help` for each command's arguments.
+
+{/* Evidence: crates/registry-coordinator/src/cli.rs, Command, CTL_REPORT_KIND;
+    products/coordinator/README.md, Create and check a project. */}
+
+## Start a project
+
+`coordinatorctl init` writes a starter into a new or empty directory, and refuses a directory that
+already has content:
+
+```sh
+coordinatorctl init --directory ./follow-up
+```
+
+The project ID is the directory name unless you pass `--id`. The starter holds four files and a
+`.gitignore` that keeps the local `.coordinator/` directory out of version control:
+
+- `workflow.yaml`, a `CoordinatorProject`, names the workflow and its version under `project`, its
+  input schema, its logical `connections` and the product each one reaches, the run's
+  `deadlineSeconds`, its `start` step, its `steps`, and its declared `outcomes`.
+- `functions.rhai` holds the pure functions the mappings call.
+- `runtime.yaml`, a `CoordinatorRuntimeConfig`, binds the logical connections for local checks.
+  The operator's deployment copy adds the deployment identity, keys, and caller policies.
+- `scenarios.yaml`, a `CoordinatorScenarios`, holds the offline test cases.
+
+One project is one flow, and its workflow ID is the flow name callers start.
+
+{/* Evidence: crates/registry-coordinator/src/cli.rs, Command;
+    products/coordinator/README.md, Create and check a project;
+    products/coordinator/examples/delayed-follow-up/workflow.yaml. */}
+
+## Write the steps
+
+Each step declares its `type`: `call`, `choose`, `wait-until`, `wait-for`, or `finish`. A call
+names a logical connection, one of the ten supported operations, an `input` mapping, and the next
+step:
+
+```yaml
+read-application:
+  type: call
+  connection: applications
+  operation: read-record
+  input:
+    type: fields
+    fields:
+      collection:
+        type: literal
+        value: applications
+      recordId:
+        type: input
+        path: /applicationId
+  next: permission
+```
+
+A reference names one value. `type: input` reads the run's input, `type: step` with a `step` reads
+an earlier call's output, and `type: literal` with a `value` supplies a JSON value. An input or
+step reference may add an RFC 6901 `path`, such as `/applicationId`, to select one member. A call
+`input` or a finish `output` is either `type: fields`, an object built member by member from up to
+64 references, or `type: function`, a pure function given up to 16 references as `arguments`.
+
+Functions read no clock. `add_seconds(instant, seconds)` and `seconds_between(first, second)`
+compute over the RFC 3339 instants a function is given, such as an input value or a field of an
+earlier call's output.
+
+{/* Evidence: products/coordinator/README.md, Create and check a project and Start from a
+    maintained project; crates/registry-coordinator/src/authoring.rs, AuthoredStep;
+    crates/registry-coordinator/src/functions.rs. */}
+
+The [configuration reference](../../reference/coordinator-configuration/) lists the ten operations
+with their effects and recovery, and the rules for external reads, typed decisions, and review
+waits. The maintained
+[example projects](https://github.com/registrystack/registry-stack/tree/main/products/coordinator/examples)
+cover a delayed follow-up, a deferred appointment, a Base Registry Engine (BReg) read under
+Casework task authority, a governed BReg action, a typed decision, a reviewed notice, an external directory read, and a
+bounded poll. Starting from the closest one is usually faster than starting from the starter.
+
+## Check and explain
+
+```sh
+coordinatorctl check --project ./follow-up --explain
+```
+
+`check` validates the graph, the function exports, references, input and outcome schemas, and
+execution bounds, and fits every mapping to the schemas it reads and feeds, before any run. A
+structural error names its file, line, column, and a repair. A mapping refusal names the step, the
+field path, what was expected, and the fix. Some errors hide the checks that depend on them, so run
+the same check again after each repair. Add `--runtime-config ./follow-up/runtime.yaml` to check
+the logical bindings too.
+
+An accepted check prints the definition digest on its `Definition:` line. With `--explain`, or
+through `coordinatorctl explain --project ./follow-up`, it also lists the steps in graph order from
+the start, one line each, with each call's product, effect, and recovery.
+
+{/* Evidence: crates/registry-coordinator/src/cli.rs, render_explain;
+    crates/registry-coordinator/src/project_check.rs;
+    crates/registry-coordinator/src/mapping_check.rs;
+    products/coordinator/README.md, Create and check a project. */}
+
+## Test against scenarios
+
+```sh
+coordinatorctl test --project ./follow-up
+```
+
+`test` runs `scenarios.yaml` with a virtual clock and fake product replies, using the same graph,
+mapping, and function semantics as the service, and reports each case by name. A case whose steps,
+end state, or outcome differs from its expectation names both sides. `test` also holds every
+computed call input to its operation's input contract and every fake success reply to its
+operation's output. A passing case proves the flow's logic, not that a product accepts the call:
+scenarios never acquire credentials or send requests.
+
+{/* Evidence: crates/registry-coordinator/src/scenarios.rs;
+    products/coordinator/README.md, Create and check a project and Add a maintained operation. */}
+
+## Package the flow
+
+```sh
+coordinatorctl package --project ./follow-up --output ./follow-up-package
+```
+
+When the project has a `scenarios.yaml`, `package` runs it first and writes nothing unless every
+case passes. It writes the flow's immutable snapshot, `definition.json`, and `SHA256SUMS` into a new
+directory, and refuses an output that already exists, so build a fresh directory for each change.
+It prints the package digest.
+
+A package has two digests:
+
+- The package digest is the SHA-256 of `SHA256SUMS`. It covers the whole package, changes whenever
+  the definition changes, and is the one the operator pins.
+- The definition digest is the SHA-256 of `definition.json`. Each run reports it as
+  `definitionDigest`, which tells you the definition a run follows after an upgrade.
+
+Once a workflow version has admitted runs, give a changed definition a new `project.version`.
+`plan` and `apply` refuse a changed definition under a version already used, with
+`coordinator.command.workflow-version-conflict`.
+
+{/* Evidence: crates/registry-coordinator/src/deployment.rs, package, plan, apply;
+    crates/registry-coordinator/src/cli.rs, Command;
+    products/coordinator/DEPLOYMENT.md, Package digest and definition digest. */}
+
+## Hand over the package
+
+Give the operator the package directory and its package digest. The operator installs the
+directory read-only and pins it as one entry of `deployment.packages`, with its `root` and the
+digest as `expectedDigest`. One deployment serves up to sixteen flows, one package each, and each
+flow is applied, upgraded, and rolled back on its own. Runs already admitted keep the definition
+they started with, and new starts use the active one.
+
+{/* Evidence: crates/registry-coordinator/src/deployment.rs, DeploymentConfig, Flows;
+    products/coordinator/README.md, Package and deploy. */}
+
+Each of the three files has an offline check command, listed under
+[Check commands](../../reference/coordinator-configuration/#check-commands) in the configuration
+reference.

+title: Deploy Registry Coordinator
+description: Create the keys, database, and runtime file for Registry Coordinator, apply and serve its flow packages, watch its metrics, and recover, erase, rotate, and restore what it holds.
+status: draft
+owner: registry-docs
+source_repos:
+  - registry-stack
+last_reviewed: unreviewed
+doc_type: how-to
+locale: en
+standards_referenced: []
+---
+
+An author has handed you one or more Registry Coordinator packages with their package digests, and
+you want the flows served. At the end of this page a `coordinator` process serves those flows
+against PostgreSQL behind your TLS edge and answers `GET /ready`, and you can inspect and recover
+its runs, erase settled payloads, rotate its keys, and restore it from a backup.
+
+Writing, checking, and packaging a flow stay with its author;
+[Author a Coordinator flow](../../configure/coordinator/) covers that side. This page starts from
+the package directories.
+
+## What you provide
+
+- **PostgreSQL 17 or newer**, with one database and two login roles: a migration role that owns
+  the schema and a runtime role that serves. Apply and startup refuse an older server.
+- **Your existing OpenID Connect issuer.** Callers present its RFC 9068 access tokens
+  (`typ: at+jwt`) to the Coordinator. For each product connection, the Coordinator obtains its own
+  token from the token endpoint that connection names, as a registered client with its own signing
+  key.
+- **A TLS terminator** in front of the service listener, which you bind to a private address.
+- **Secret files** for three keys, the two database URLs, and each connection credential, owned by
+  the service user.
+- **Durable storage for the audit file**, at an absolute path the service user can write.
+- **The package directory and package digest of each flow**, up to sixteen flows in one deployment.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Create the keys and secrets, Create the database
+    and roles, and Configure the deployment; crates/registry-coordinator/src/access.rs,
+    access_token_typ_set. */}
+
+## Install the binaries
+
+Install `coordinator` and `coordinatorctl` from the same release, as
+[Get `coordinatorctl`](../../configure/coordinator/#get-coordinatorctl) describes, and use absolute
+executable paths in your service definition. Install each package directory read-only and keep the
+package digest its author gave you. The service reads its runtime file from an absolute path;
+`coordinatorctl` also accepts a path relative to the current directory.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Install and package and Apply and start. */}
+
+## Create the keys and secrets
+
+Create every secret as the user that runs `coordinator` and `coordinatorctl`. The runtime file
+names a secret as `secret:file/<name>`, read from the file `<name>` directly under the file
+provider's `root`. That file must be a regular file owned by the service user, with mode `0400` or
+`0600` and exactly one link.
+
+The Coordinator uses three keys, each exactly 32 random bytes in its own file:
+
+- The **payload state key** encrypts the run state held in PostgreSQL. You can add versions of it
+  later.
+- The **admission key** derives start identities, owner hashes, and command keys. It stays the same
+  for the deployment's lifetime and differs from every state key.
+- The **audit key** derives the keyed references the audit journal records, such as `runRef` and
+  `actorRef`.
+
+```sh
+install -d -m 0700 /run/registry-coordinator/secrets
+(umask 077 && openssl rand -out /run/registry-coordinator/secrets/state-key-1 32)
+(umask 077 && openssl rand -out /run/registry-coordinator/secrets/admission-key 32)
+(umask 077 && openssl rand -out /run/registry-coordinator/secrets/audit-key 32)
+```
+
+:::caution[Keep every key under backup custody]
+A restored database needs every state key version its rows were written with, and the admission
+key the deployment has used from the start. Back up each key file under custody separate from the
+database backups.
+:::
+
+The database URLs are secrets too. Institutional connections use `sslmode=require`:
+
+```sh
+(umask 077 && printf '%s' 'postgresql://coordinator_runtime:<runtime-password>@db.example.org:5432/coordinator?sslmode=require' \
+  > /run/registry-coordinator/secrets/runtime-database-url)
+(umask 077 && printf '%s' 'postgresql://coordinator_migration:<migration-password>@db.example.org:5432/coordinator?sslmode=require' \
+  > /run/registry-coordinator/secrets/migration-database-url)
+```
+
+Write each connection credential the same way, such as the signing key a connection's
+`authorization.signingKeyRef` names. A Casework connection that receives completion events also
+names a bearer token that Casework presents to the Coordinator. Generate it as visible ASCII and
+give Casework the same value under its own secret reference:
+
+```sh
+(umask 077 && openssl rand -hex 32 > /run/registry-coordinator/secrets/review-completion-token)
+```
+
+Secret values never appear in a diagnostic or a log.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Create the keys and secrets and Backup and
+    restore. */}
+
+## Create the database and roles
+
+As a PostgreSQL administrator, create the two roles and the database, and let only those roles
+connect:
+
+```sql
+CREATE ROLE coordinator_migration LOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE
+  NOINHERIT NOBYPASSRLS PASSWORD '<migration-password>';
+CREATE ROLE coordinator_runtime LOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE
+  NOINHERIT NOBYPASSRLS PASSWORD '<runtime-password>';
+CREATE DATABASE coordinator;
+REVOKE ALL ON DATABASE coordinator FROM PUBLIC;
+GRANT CONNECT ON DATABASE coordinator TO coordinator_migration, coordinator_runtime;
+GRANT CREATE ON DATABASE coordinator TO coordinator_migration;
+```
+
+These are the only grants you make. `apply` creates the schema the runtime file's `namespace`
+names, owned by the migration role, and grants the runtime role what it needs there: `USAGE` on the
+schema, `SELECT`, `INSERT`, `UPDATE`, and `DELETE` on `runs`, `jobs`, `admission_lock`, and
+`review_waits`, `SELECT` on `control`, `coordinator_activations`, and `coordinator_migrations`, and
+`UPDATE` on the four recovery-hold columns of `control`. A namespace starts with `coordinator_` and
+is at most 60 characters.
+
+`apply`, `deployment-status`, and startup refuse a runtime role that is a superuser, bypasses
+row-level security, belongs to the migration role directly or indirectly, can create objects in the
+schema, holds `TRIGGER`, or owns objects there. Each service process keeps a pool of at most 32
+sessions as the runtime role, so allow 32 connections per process in the role's connection limit
+and in the server's `max_connections`.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Create the database and roles. */}
+
+## Write the runtime file
+
+The runtime file is a `CoordinatorRuntimeConfig`. Start from the author's `runtime.yaml`, keep its
+`secretProviders`, `database`, `namespace`, and logical `connections`, and add a `deployment`
+block. Keep the file outside the packages, and put no secret value in it:
+
+```yaml

+| Key under `deployment` | What it sets |

+| `runtimeRole` | The runtime role's name. It must match the role in `database.runtimeUrlRef`. |
+| `packages` | One entry per flow, up to sixteen: the package directory as `root` and its package digest as `expectedDigest`. |
+| `listener` | The service socket. `operator-controlled-upstream` puts it behind your TLS terminator; `development-loopback` binds only loopback, for local work. |
+| `metricsListener` | Optional. A concrete loopback or private address on a nonzero port, other than the service socket, that serves `/metrics`. Without it no metrics are served. |
+| `authentication` | The issuer, audience, signing-key source, admitted clients, and caller policies. |
+| `auditFile` and the key references | The absolute audit file path, the audit key, the state key versions with the one that writes, and the admission key. |
+
+{/* Evidence: products/coordinator/examples/single-flow-runtime.yaml;

+    crates/registry-coordinator/src/runtime.rs, KIND. */}
+
+### Write the caller policies
+
+`allowedClients` is a nonempty list of exact client IDs, and each client in it needs one policy;
+the Coordinator refuses an omitted or empty list and `unrestricted`. The run actions `start`,
+`status`, `inspect`, `retry-same`, `cancel`, and `reconcile` reach only the flows the policy lists
+in `flows`. The deployment-wide actions `doctor`, `restore-hold`, `release-restore-hold`,
+`release-admission-hold`, `complete-execution-recovery`, and `retain` act on every flow at once,
+including flows added later, and need `operator: true`. A policy that lists only deployment-wide
+actions omits `flows`. Do not give an institutional producer operator authority.
+
+The Coordinator reads a token's scopes from its `registry_scopes` claim. For an issuer that puts
+them in the standard `scope` claim, set `scopeClaim: scope` under `deployment.authentication`. A
+run belongs to the verified `iss` and `sub` of the token that started it, never to an input field.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Configure the deployment;
+    crates/registry-coordinator/src/access.rs, scope_claim. */}
+
+### Bind the connections
+
+Each logical connection a flow uses binds to one product endpoint and one service identity. Some
+operations add rules of their own:
+
+- **`invoke-breg-action`** needs a Base Registry Engine (BReg) connection with an ordinary service
+  `authorization`, a permitted `profile`, and no `authorization.taskAuthority`. Keep a separate
+  connection for record reads under Casework task authority when a flow needs both.
+- **`external-get`** reads through an entry under `externalHttpConnections`, with a `baseUrl`, exact
+  `paths`, optional `queryParameters` and `authorization`, and a required `responseSchema`. An
+  attempt times out after 2000 milliseconds and a response stops at 65,536 bytes by default, and you
+  can lower both. Use HTTPS; plain HTTP needs an explicit numeric loopback address.
+- **`evaluate-decision`** calls an entry under `decisionConnections` that names `system-one` or
+  `openai-decisions`, a `baseUrl`, a `model`, and either `authorization.bearer` with a `tokenRef`
+  and `principal` or `authorization.local` on numeric loopback. Requests and responses stop at
+  65,536 bytes and an attempt at 8000 milliseconds by default. Review what your mappings disclose
+  before you bind a remote model; a model call may incur cost.
+- **A Scheduling connection with `authorization.taskAuthority`** also needs an
+  `observationAuthorization` with receipt-read scopes, the same token endpoint, client, and
+  resource, and no `taskAuthority`. Recovery reads receipts with it, after the original grant has
+  expired or been revoked. Only a task-bound Scheduling connection takes it.
+
+Connection names are unique across `connections`, `externalHttpConnections`, and
+`decisionConnections`, with at most 16 in all. The
+[configuration reference](../../reference/coordinator-configuration/) lists every key.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Configure the deployment and Recover safely. */}
+
+### Wake waiting runs from Casework
+
+`submit-review-request`, `cancel-review-request`, and a `wait-for` step use a Casework connection
+that acts as one Casework review producer:
+
+```yaml
+connections:
+  review:
+    product: casework
+    baseUrl: https://casework.example.org
+    profile: coordinator-producer
+    producer: coordinator
+    authorization:
+      tokenEndpoint: https://issuer.example.org/oauth/token
+      clientId: coordinator-review-producer
+      signingKeyRef: secret:file/review-jwk
+      resource: urn:example:casework
+      scopes: [casework:review]
+    completion:
+      recipientBinding: coordinator-v1
+      bearerTokenRef: secret:file/review-completion-token
+    resultCheckSeconds: 900
+```
+
+`profile` names the Casework access profile the producer's client is admitted to, and `producer`
+names the producer's `id` in the Casework project's `reviewProducers`. The `authorization` obtains a
+token with the issuer and subject that producer declares; a Casework connection takes no task
+authority. A waiting run reads the review result through this connection every
+`resultCheckSeconds`, from 60 to 86,400 and 900 by default. Each read is one request to Casework per
+waiting run.
+
+The `completion` block lets Casework wake a waiting run sooner. On the Casework side, the
+producer's `completion` names a destination and the same recipient binding, and that destination
+points at `https://<coordinator-host>/v1/review-completions` with Casework's own reference to the
+same token. The Coordinator accepts no custom header, so present the token as a bearer token.
+[Review kinds and producers](../../configure/casework/#review-kinds-and-producers) covers that
+side. `recipientBinding` is 1 to 256 visible ASCII characters and differs between Casework
+connections. An event brings the waiting run's next read forward and never starts a run. Without a
+`completion` block the Coordinator refuses every event and waits rely on result reads, so lower
+`resultCheckSeconds` when events cannot reach it. You can change `completion` or
+`resultCheckSeconds`, or rotate the completion token, while runs wait.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Configure the deployment;
+    crates/registry-coordinator/src/completion.rs, receive_review_completion. */}
+
+### Check the runtime file
+
+```sh
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml check
+```
+
+The check reads no credential and contacts no endpoint. It reports each refusal with its position
+in the file and a repair. Add `--deny-warnings` to refuse warnings too, including checks deferred
+until environment values are supplied.
+
+{/* Evidence: crates/registry-coordinator/src/cli.rs, Check;
+    products/coordinator/DEPLOYMENT.md, Configure the deployment. */}
+
+## Apply and start
+
+```sh
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml plan
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml deployment-status
+coordinator --runtime-config /etc/registry-coordinator/runtime.yaml
+```
+
+- `plan` reports, for each flow, whether `apply` would `install`, `replace`, leave `unchanged`, or
+  `remove` its package, with the listed and active package digests and the `flowsDigest` of the
+  listed set. Only `apply` reads the migration URL.
+- `apply` uses the migration credential. It verifies each pinned package, migrates the schema,
+  grants the runtime role, and records each flow's active package. It is the only command that
+  migrates.
+- `deployment-status` uses the runtime credential only. It checks the pinned packages, the database
+  identity, the migrations, the runtime role's effective authority, and the bindings of live runs,
+  and reports `status: checked` with `databaseId`, `flowsDigest`, each flow's package digest,
+  `schemaVersion`, `runtimeRole`, and the `active` activation.
+- `coordinator` verifies the same things before it serves, and never migrates or activates.
+
+A `plan` or `apply` that finds a pinned package whose content no longer matches its digest refuses
+with `coordinator.deployment.refused`; restore the exact package. One that finds a changed
+definition under a workflow version runs already use refuses with
+`coordinator.command.workflow-version-conflict`; ask the author for a new `project.version`.
+
+Startup also checks that each live run's endpoint, registered identity, scopes, and task authority
+are the ones it started with. When a change to the runtime file breaks one, restore the original
+binding, or investigate with dispatch and admissions disabled:
+
+```sh
+coordinator --runtime-config /etc/registry-coordinator/runtime.yaml --recovery-only
+```
+
+A recovery-only service still verifies the package, database, schema, role, and key custody, and its
+`/ready` stays false.
+
+The service writes JSON lines to standard error at the `info` level. A worker poll that fails logs a
+warning with its code, pauses for 1 second, doubling up to 30 seconds while failures continue, and
+repeats the deployment check. While the database is unreachable the worker logs
+`store-unavailable`, `/ready` answers 503, and starts answer 503 `service.unavailable`; the service
+keeps running and logs `worker loop resumed` once a poll succeeds. Any other refusal stops the
+service with exit status 1 and its code and fix on standard error: `deployment.refused` when an
+apply moved the activation, and `state-key-custody` when key custody no longer matches what apply
+registered.
+
+SIGTERM or SIGINT stops the service within 15 seconds: the listener finishes the requests it is
+answering, the worker finishes the attempt in flight, and the service logs `stopped` and exits 0.
+Give your supervisor a stop timeout of at least 15 seconds. An attempt still unfinished when the
+service is killed keeps its lease until the lease expires, and a worker then holds it for operator
+review.

+    digest; crates/registry-coordinator/src/service.rs, SHUTDOWN_GRACE, recovery_only. */}
+
+### Check health and run doctor
+
+Keep the operator's access token in an owner-readable file, and pass its path, never its value:
+
+```sh
+curl -fsS http://127.0.0.1:8108/health
+curl -fsS http://127.0.0.1:8108/ready
+coordinatorctl doctor --url https://coordinator.example.org --token-file /run/operator-token
+```
+
+`/health` answers `{"live":true}` while the process answers. `/ready` answers `{"ready":true}`, or
+HTTP 503 with `{"ready":false}` while the service cannot accept work. Each `/ready` probe checks the
+schema, activation, role, state key custody, audit, and holds, and reuses the scan of live bindings
+for up to 30 seconds. Keep both probes on the private listener.
+
+In the doctor report, `activationReady` and `state.auditReady` are `true` on a serving deployment,
+and `state.restoreHold` and `state.admissionsHold` are `false` until a hold is placed.
+`state.states` counts runs by state, `state.uncertain` counts steps waiting for an operator,
+`state.restoreReviewRequired` counts runs that need restore review, and `state.oldestDueAt` is the
+earliest next attempt. `state.terminalPayloads` and `state.oldestTerminalPayloadAt` show what
+retention can erase.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Check health and run doctor. */}
+
+### Change the flows
+
+Each flow's package applies on its own. To add a flow, list its package; to upgrade or roll one
+back, change only that entry's `root` and `expectedDigest`. `apply` leaves every other flow's
+active package and runs untouched. Runs in flight on a replaced flow keep the definition they
+started with, and new starts use the replacement. An apply that changes the listed set fences the
+services started under the previous set, so restart every service after each apply. One deployment
+is one trust domain: flows that must not share connections belong in separate deployments.
+
+Dropping an entry never retires a flow by itself. `plan` and `apply` refuse an active flow missing
+from the list with `coordinator.deployment.flow-unlisted` until you list it again or name it:
+
+```sh
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml plan --remove-flow governed-action-follow-up
+coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply --remove-flow governed-action-follow-up
+```
+
+Removal is refused with `coordinator.deployment.flow-live-runs` while the flow has a run that is
+running, waiting, uncertain, recoverable, or awaiting restore review. Let those runs settle or
+cancel them first, because a removed flow leaves no definition to finish them under. A removed
+flow's ended runs stay readable, and starts naming it are refused.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Add, upgrade, roll back and remove a flow;

+
+## Watch metrics
+
+```sh
+curl -fsS http://127.0.0.1:9108/metrics
+```
+
+The metrics listener serves Prometheus text, and every label takes a closed set of values:
+
+| Series | Type | Labels |
+| --- | --- | --- |
+| `coordinator_runs_admitted_total` | counter | none |
+| `coordinator_runs_finished_total` | counter | `state`: `finished`, `failed`, `cancelled`, `cancelled-after-effect`, `expired` |
+| `coordinator_step_attempts_total` | counter | `outcome`: `accepted`, `transient`, `permanent`, `maybe-sent`, `unavailable` |
+| `coordinator_authentication_refusals_total` | counter | `reason`: `refused`, `policy`, `unavailable` |
+| `coordinator_dispatch_jobs` | gauge | `state`: `pending`, `leased`, `unknown` |
+
+Counters are per process and start at zero when a process starts. `maybe-sent` counts an attempt
+whose effect is uncertain and waits for an operator. `coordinator_dispatch_jobs` is read from the
+database on each scrape with a 2-second bound; when the database cannot answer, that scrape has no
+`coordinator_dispatch_jobs` samples rather than zeros, so alert on the gauge going absent as well as
+on its value. No label carries a flow, run, input, or principal; per-flow and per-run detail lives
+in the audit journal and in `coordinatorctl status` and `inspect`. Bind the metrics listener where
+only your monitoring can reach it.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Watch metrics;

+
+## Admit and inspect runs
+
+Callers start runs through the API or the Rust, Node.js, and Python clients. To check a deployment
+from the command line, start one run with a key file you keep for that logical start and reuse
+through its recovery. `input.json` holds the flow's input, in the shape its author declared:
+
+```sh
+umask 077
+python3 -c 'import uuid; print(uuid.uuid4())' > ./idempotency-key
+coordinatorctl start --flow delayed-follow-up --input ./input.json --key-file ./idempotency-key \
+  --url https://coordinator.example.org --token-file /run/producer-token
+coordinatorctl status --run <run-id> \
+  --url https://coordinator.example.org --token-file /run/producer-token
+coordinatorctl inspect --run <run-id> \
+  --url https://coordinator.example.org --token-file /run/operator-token
+```
+
+A start runs under the flow's active definition. A caller whose policy does not list the flow is
+refused with HTTP 403 `operation.not-authorized`, and a flow the deployment does not serve with
+HTTP 404 `flow.not-served`. A start that reuses a key returns the original run.
+
+`inspect` shows bounded step state, never inputs, raw product responses, or prepared commands. Its
+`recovery.operation` describes the current call's recovery and whether the product offers a
+read-only receipt. `retryAllowed` and `reason` describe scheduling eligibility only; neither proves
+that the product would still authorize the call. `coordinatorctl list --limit <n>` returns the most
+recent runs, newest first, 20 by default and at most 100, with no paging cursor and no state
+filter.
+
+`retry-same`, `cancel`, `reconcile`, `restore-hold`, and `release-restore-hold` take a `--reason`:
+a bounded investigation reference such as `incident-2026-10-12` that holds no personal data. The
+audit journal records a keyed reference to it, so keep the investigation record itself outside the
+Coordinator.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Admit and inspect work;
+    crates/registry-coordinator/src/cli.rs, Command, RetrySame, RestoreHold. */}
+
+## Recover a run
+
+The Coordinator retries a call by itself only after a definite retryable answer, one the receiving
+product reports it did not act on, and it resends the saved command and key. A call step makes at
+most ten attempts, with waits that roughly double from 1 second to 256 seconds; the nine waits add
+up to between 255.5 and 511 seconds. When Messaging or an external service sends a `Retry-After`,
+the next attempt waits at least that long, up to five minutes, so the waits never exceed 45 minutes
+in total. A retry that would
+start at or after the run deadline is never scheduled, and the run ends `expired`. After the tenth
+attempt the run reports `failed` and waits for you. An uncertain answer is never retried
+automatically.
+
+An `external-get` reply with status 429, 502, 503, or 504 is retried as `external-rate-limited` or
+`external-unavailable`. The tenth attempt delivers that status to the flow like any other reply.
+
+Inspect before you act, then choose:
+
+- **`reconcile`** asks Messaging or Scheduling for its receipt of the stored command under the
+  original key and owner. A missing or expired receipt, or an unavailable product, does not prove
+  the command was never received. A BReg action has no read-only receipt, so `reconcile` leaves it
+  unresolved; for a Casework review request it reports `reconciliation-unavailable`.
+- **`retry-same`** sends the original body, key, binding, and authority again, when the product's
+  recovery contract and the original deadline permit it. A BReg action checks current metadata and
+  fresh authority first, and stops on a changed contract, denied authority, or stale condition.
+  Casework answers a repeated key with its stored response while it keeps one.
+- **`cancel`** stops future calls where it can. It does not roll back an appointment, action, or
+  message a product already accepted.
+
+```sh
+coordinatorctl reconcile --run <run-id> --reason incident-2026-10-12 \
+  --url https://coordinator.example.org --token-file /run/operator-token
+coordinatorctl retry-same --run <run-id> --reason incident-2026-10-12 \
+  --url https://coordinator.example.org --token-file /run/operator-token
+```
+
+:::caution[A fresh idempotency key is a fresh operation]
+Starting the same work again under a new key can perform its effects a second time. Settle an
+uncertain call with `reconcile` or `retry-same`, which keep its original key, and do not infer
+success or absence from an ordinary record read.
+:::
+
+Some failures need a change, not a retry:
+
+- **`wait-for`** reads change nothing in Casework, so an outage shorter than the timeout leaves the
+  wait open and never fails the run. A read Casework refuses fails the run with its code, and
+  `retry-same` resumes the reads under the original timeout. `wait-timed-out`,
+  `review-request-unknown`, and `review-result-expired` end the wait for good. Cancelling a waiting
+  run leaves its review request open in Casework, so withdraw it in Casework when no one needs to
+  act on it.
+- **`mapping-invalid`** means a call succeeded but the mapping after it did not. The run keeps that
+  call's output, and `retry-same` cannot repeat the accepted call. Inspect the existing effect
+  before you start a new run under a corrected workflow version.
+- **`invalid-command`** means a computed call input fell outside its operation's contract, before
+  anything was sent. The status reports `failurePath`, an RFC 6901 path into the input, and never
+  the value. Correct the mapping in a new workflow version, or the data it reads, and start a new
+  run.
+- **An `evaluate-decision` call with an unknown result**, including after HTTP 429, is held as
+  `hold-after-dispatch`: `retry-same` and `reconcile` are refused, and `cancel` cannot undo what the
+  provider processed.
+
+When configuration drift blocks recovery, restore the original downstream binding. Rotate a
+connection's key material under the same registered identity rather than changing the identity.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Recover safely and Configure the deployment;
+    crates/registry-coordinator/src/cli.rs, Reconcile, RetrySame. */}
+
+## Erase ended payloads
+
+`retain` erases the payloads of runs that ended before a cutoff, at most `--limit` records per
+call, from 1 to 100 and 100 by default:
+
+```sh
+coordinatorctl retain --before 2026-07-01T00:00:00Z --limit 100 \
+  --url https://coordinator.example.org --token-file /run/operator-token
+```
+
+It keeps bounded tombstones of the spent start and command identities, and never erases live or
+uncertain work. Take the cutoff, an RFC 3339 instant in the past, from your institution's approved
+retention policy. An erased run can no longer be retried or reconciled, and asking answers
+`run.payload-erased`.
+
+:::danger[Erasing cannot be undone]
+`retain` deletes the payloads it selects permanently. Removing a state key version before the data
+written under it is erased has the same effect on every run it encrypted: that state becomes
+unreadable, and the runs can neither run nor be disclosed safely.
+:::
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Recover safely;
+    crates/registry-coordinator/src/cli.rs, Retain;
+    docs/site/src/data/coordinator-api.yaml. */}
+
+## Rotate and replace keys
+
+Run every command as the service user.
+
+### Rotate the payload state key
+
+Rotation adds a key version and makes it the one that writes. Runs written under an older version
+still read with it, so the deployment keeps every registered version for its lifetime.
+
+1. Create the key file for the next version:
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/state-key-2 32)
+   ```
+
+2. Add the version to `deployment.stateKeys`, keep every version already listed, and set
+   `activeStateKey` to the new one:
+
+   ```yaml
+   deployment:
+     activeStateKey: 2
+     stateKeys:
+       "1":
+         keyRef: secret:file/state-key-1
+       "2":
+         keyRef: secret:file/state-key-2
+   ```
+
+3. Put the edited runtime file and the new key file in place for every service, then apply and
+   check:
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml apply
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml deployment-status
+   ```
+
+4. Restart every service with the edited runtime file as soon as apply succeeds.
+
+Until apply registers the new version, startup and `deployment-status` refuse the edited file with
+`state-key-custody`. Once apply has registered it, a service still running with the previous file
+answers starts with 409 `deployment.refused` and `/ready` with 503, and stops with exit status 1 at
+its next poll. A runtime file that omits a registered version or names different key bytes for one
+is refused with `state-key-custody` too.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Rotate the payload state key. */}
+
+### Rotate the audit key
+
+The database keeps no record of the audit key, so its rotation needs no apply.
+
+1. Create the new key file:
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/audit-key-2 32)
+   ```
+
+2. Point `deployment.auditKeyRef` at it:
+
+   ```yaml
+   deployment:
+     auditKeyRef: secret:file/audit-key-2
+   ```
+
+3. Check the runtime file, then restart every service with it, so all of them write under the same
+   key:
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime.yaml check
+   ```
+
+The same run or actor gets a different reference under each key, so journal records from before
+the rotation do not join records from after it. Keep the old key with the journal it wrote: an
+investigator needs it to match a known run or actor to those records.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Rotate the audit key. */}
+
+### Replace a compromised admission key
+
+The admission key stays the same for the deployment's lifetime, and apply refuses a different one
+with `state-key-custody`. When the key is exposed, close the deployment and admit new work in a
+fresh one.
+
+1. Stop admissions. Remove `start` from each caller policy's `actions`, remove a policy left with
+   no action along with its client in `allowedClients`, and restart the service. Starts are then
+   refused with HTTP 403 `operation.not-authorized`, while status, inspection, and operator actions
+   keep working. Do not use `restore-hold` for this: it also stops dispatch, so runs in flight
+   cannot finish.
+
+2. Let runs finish, or cancel the ones you will not wait for, and settle each uncertain step as
+   [Recover a run](#recover-a-run) describes:
+
+   ```sh
+   coordinatorctl doctor --url https://coordinator.example.org --token-file /run/operator-token
+   coordinatorctl list --limit 100 --url https://coordinator.example.org --token-file /run/operator-token
+   coordinatorctl cancel --run <run-id> --reason incident-2026-10-12 \
+     --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+3. Stop the service. Keep its runtime file, namespace, keys, and audit journal for as long as you
+   need its history: the old runs stay in the old namespace.
+
+4. Create a new admission key file:
+
+   ```sh
+   (umask 077 && openssl rand -out /run/registry-coordinator/secrets/admission-key-2 32)
+   ```
+
+5. Write a runtime file for the new deployment with a new `namespace`, a new
+   `deployment.databaseId`, and the new key, and restore `start` to the caller policies:
+
+   ```yaml
+   namespace: coordinator_follow_up_2
+   deployment:
+     databaseId: coordinator-institution-follow-up-2
+     admissionKeyRef: secret:file/admission-key-2
+   ```
+
+6. Plan, apply, check, and start the new deployment:
+
+   ```sh
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime-2.yaml plan
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime-2.yaml apply
+   coordinatorctl --runtime-config /etc/registry-coordinator/runtime-2.yaml deployment-status
+   coordinator --runtime-config /etc/registry-coordinator/runtime-2.yaml
+   ```
+
+:::caution[The new deployment does not know the old keys]
+The new deployment has no record of the idempotency keys the old one spent, so a key reused
+against it admits a new run. Tell producers to send a fresh start only for work the old deployment
+did not admit.
+:::
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Replace a compromised admission key. */}
+
+## Back up and restore
+
+Back up PostgreSQL, every state key version still needed, the admission key, the audit key, the
+durable audit stream, and the exact package of every listed flow, and test the restore procedure.
+
+:::danger[Never restore the database without its keys]
+Restore the state key versions and the admission key from their custody with the database. A
+replacement state key cannot read state written under the original, and apply refuses an admission
+key other than the one the deployment has always used.
+:::
+
+A backup can predate an effect a product already accepted, so a restored deployment starts held:
+
+1. Stop or externally fence the old service and every worker, including replicas that use the same
+   database or credentials. Never start an ordinary worker on the restored database.
+
+2. Restore the database and put the keys, audit stream, and packages back. Start a maintenance
+   instance under your supervisor with
+   `coordinator --runtime-config /etc/registry-coordinator/runtime.yaml --recovery-only`. It serves
+   authenticated recovery operations and never dispatches. Place the restore hold through it, which
+   also places a separate admission hold:
+
+   ```sh
+   coordinatorctl restore-hold --reason restore-2026-10-12 \
+     --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+3. Inspect and reconcile every command that may have been sent after the backup, through the
+   receiving products' original-key receipts. Receipt expiry limits what you can establish: keep
+   unresolved work held and consult the product's own records, and never infer that an effect did
+   not happen.
+
+4. When complete point-in-time recovery or retained execution evidence establishes the history,
+   attest it while the hold remains. This clears review marks for resolved work, holds safe pending
+   work as failed work for an explicit `retry-same` or `cancel`, and starts nothing:
+
+   ```sh
+   coordinatorctl complete-execution-recovery --recovery-reference restore-2026-10-12 \
+     --execution-history-complete --prior-deployment-fenced \
+     --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+5. Record the fencing and reconciliation evidence, then release the restore hold. Release refuses
+   with `restore.unresolved` while held work is unresolved, and leaves the admission hold in place:
+
+   ```sh
+   coordinatorctl release-restore-hold --reason restore-2026-10-12 \
+     --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+6. Inspect the held work. Use `retry-same` where the original deadline still permits it, or cancel
+   the work and let retention erase it.
+
+7. Keep admissions held until complete point-in-time recovery or retained admission evidence
+   establishes every key the deployment spent, because an older backup can omit whole admissions.
+   Then reopen them:
+
+   ```sh
+   coordinatorctl release-admission-hold --recovery-reference restore-2026-10-12 \
+     --admission-history-complete --prior-deployment-fenced \
+     --url https://coordinator.example.org --token-file /run/operator-token
+   ```
+
+The `--admission-history-complete`, `--execution-history-complete`, and `--prior-deployment-fenced`
+flags are audited operator attestations, not automated proof, so keep the evidence behind them
+under institutional custody. Do not cancel a restored run to erase its unresolved history. The
+[deployment runbook](https://github.com/registrystack/registry-stack/blob/main/products/coordinator/DEPLOYMENT.md#backup-and-restore)
+gives the full rules for each kind of held work, including a cancelled evaluation whose outcome is
+unknown.

+
+## Codes you see
+
+Each surface names a refusal in its own vocabulary:
+
+- **The service's standard error** carries the raw failure code: `store-unavailable` while the
+  database is unreachable, `deployment.refused` or `state-key-custody` when the service stops, and
+  `live-binding-conflict` when startup finds a live run's binding changed.
+- **`coordinatorctl`** prefixes its diagnostic codes with `coordinator.`, as in
+  `coordinator.deployment.refused`, `coordinator.deployment.flow-unlisted`,
+  `coordinator.deployment.flow-live-runs`, `coordinator.command.workflow-version-conflict`,
+  `coordinator.command.state-key-custody`, and `coordinator.command.live-binding-conflict`.
+- **HTTP answers** carry RFC 9457 problem documents whose `code` comes from a closed catalogue.
+- **A run's status** carries the code its failed step ended with, such as `mapping-invalid`,
+  `invalid-command`, or `wait-timed-out`, which [Recover a run](#recover-a-run) covers.
+
+The HTTP codes an operator acts on:
+
+- `service.unavailable` (503): the database, audit stream, or token verifier is unavailable. Try
+  again after it recovers.
+- `audit.response-unavailable` (503): the operation may have completed, but its audited result was
+  not released. Inspect the run before repeating the operation.
+- `deployment.refused` (409): the activation, runtime file, or key custody check failed.
+- `deployment.activation-changed` (409): an apply changed the active packages after the service
+  started. Restart it with the runtime file apply used.
+- `binding.conflict` and `binding.live-conflict` (409): the runtime file changed connection settings
+  a run uses. Restore the original settings and restart the service, or investigate in
+  recovery-only mode.
+- `execution.held` and `admission.held` (409): the restore hold or the admission hold is in place.
+- `admission.recovery-only` (409): this instance is in recovery-only mode and admits no runs.
+- `restore.hold-required`, `restore.unresolved`, `restore.review-required`, and
+  `restore.lease-incompatible` (409): a restore step is out of order, or held work still needs
+  review.
+- `reconcile.unsupported`, `reconcile.refused`, `reconcile.raced`, `receipt.expired`, and
+  `retry.refused` (409): the held call cannot be reconciled or retried that way, or changed while it
+  was reconciled. Inspect it again. An expired receipt is not evidence that the command was never
+  sent.
+- `run.payload-erased` (409): retention erased the run's payloads.
+
+The [API reference](../../reference/apis/registry-coordinator/#problem-documents-and-codes) lists

+
+Registry Coordinator serves one HTTP surface for starting a run of a served flow, following and
+recovering that run, operating the deployment, and taking Casework's review completion events.
+Every route except liveness, readiness, and completion events presents a bearer access token, and
+the caller policy that token resolves to decides what the caller may do. The contract is pre-1.0 and
+carries no frozen compatibility promise.
+
+[Open the Registry Coordinator API operations](../coordinator/) for every route, parameter, schema,
+and reachable problem code. This page holds the authentication, ownership, idempotency, and
+recovery rules those operations assume.
+
+## Contract boundary
+
+Every caller request presents `Authorization: Bearer <token>` holding an RFC 9068 access token,
+`typ: at+jwt`, signed with RS256 or ES256 by the one issuer the deployment names, for its audience,
+to a client listed in its `allowedClients`, with a lifetime of at most one hour. The token's scopes
+are read from `registry_scopes` unless the deployment sets `scopeClaim`. A missing, malformed, or
+unverified token answers `401 authentication.refused` with `WWW-Authenticate: Bearer`.
+
+{/* Evidence: crates/registry-coordinator/src/access.rs, access_token_typ_set, scope_claim;
+    products/coordinator/DEPLOYMENT.md, Configure the deployment. */}
+
+Each verified client resolves one caller policy, which lists the scopes it requires and the actions
+it allows:
+
+- The run actions `start`, `status`, `inspect`, `retry-same`, `cancel`, and `reconcile` reach only
+  the flows the policy lists in `flows`.
+- The deployment-wide actions `doctor`, `restore-hold`, `release-restore-hold`,
+  `release-admission-hold`, `complete-execution-recovery`, and `retain` act on every flow at once
+  and need `operator: true` on the policy.
+
+A resolved caller refused an action answers `403 operation.not-authorized`. Run ownership and the
+idempotency scope come from the token's exact verified `iss` and `sub`, never from input fields;
+input identifiers and grant references manufacture no caller authority. A caller allowed to start
+a run gains no authority over the products its flow calls: each call uses the identity the operator
+configured for that connection, and the receiving product decides it.
+
+{/* Evidence: products/coordinator/DEPLOYMENT.md, Configure the deployment;
+    products/coordinator/README.md, Package and deploy;
+    products/coordinator/PRODUCT-CONTRACT.md, Execution and authority. */}
+
+## Start a run
+
+`POST /v1/runs` takes a `Start` body with exactly two members: `flow`, the served flow's name of 1
+to 128 characters, and `input`, which the flow's declared input schema checks. It requires an
+`Idempotency-Key` header of 1 to 256 bytes. An admitted start answers `200` with the run's status,
+admitted under the named flow's active definition.
+
+The same key from the same issuer and subject returns the original run rather than creating new
+work, and the same key with different input answers `409 idempotency.key-reused`. A new flow version
+cannot reinterpret a repeated key. A fresh key is a fresh run, so a client that does not know
+whether a start was admitted resends it under its original key.
+
+{/* Evidence: crates/registry-coordinator/src/http.rs, start-key-invalid;
+    products/coordinator/generated/openapi/coordinator.openapi.json;
+    products/coordinator/DEPLOYMENT.md, Admit and inspect work;
+    products/coordinator/README.md, Package and deploy. */}
+
+A start is refused before admission when:
+
+- the caller's policy does not list the flow, with `403 operation.not-authorized`;
+- the policy lists the flow but the deployment does not serve it, with `404 flow.not-served`;
+- the input does not satisfy the flow's input schema and value bounds, with `400 input.invalid`;
+- the instance runs in recovery-only mode, with `409 admission.recovery-only`;
+- a restore left admissions held, with `409 admission.held`.
+
+## Read and inspect runs
+
+`GET /v1/runs/{run}` answers the run's `RunStatus`: its workflow ID and version, its
+`definitionDigest` and `bindingDigest`, its current step and state, when it was admitted and when
+its deadline falls, whether an effect is `uncertain`, whether cancellation was requested, and
+whether it needs restore review. A finished run adds its `outcome` and the reviewed `output` its
+flow declares. A failed run adds its `failureCode`, and `failurePath` when the failure concerns a
+call input: an RFC 6901 pointer into that input, never the value.
+
+A run that does not exist, a run another caller owns, and a run in a flow the caller's policy does
+not list all answer the same `404 run.not-visible`. An operator policy reaches every owner's runs
+in the flows it lists.
+
+{/* Evidence: products/coordinator/generated/openapi/coordinator.openapi.json, RunStatus;
+    crates/registry-coordinator/src/http.rs, run_caller, run-absent;
+    products/coordinator/README.md, Observe and recover. */}
+
+`GET /v1/runs` answers at most 100 of the most recently admitted runs the caller may see, newest
+first. `limit` takes 1 to 100 and defaults to 20; any other value answers
+`400 request.limit-out-of-range`. The list has no paging cursor and no state filter, so a client
+keeps the run ID a start returns to read an older run.
+
+`GET /v1/runs/{run}/inspect` answers the run, one entry per step with its state, attempt count,
+whether its command is prepared, whether its effect is uncertain, and whether its receipt expired,
+and a `recovery` block. `recovery.retryAllowed` and `recovery.reason` describe whether the run can
+be scheduled again. For a compatible current call, `recovery.operation` names the pinned operation's
+ID, version, product, effect, key and preparation requirements, recovery semantics, and
+`readReceipt` capability. Neither proves current product authority or that an original-key receipt
+exists. No status, list, or inspection answer carries a run's input, a product response, or a
+prepared command.
+
+{/* Evidence: products/coordinator/generated/openapi/coordinator.openapi.json, RunInspection,
+    StepStatus, OperationIdentity; products/coordinator/README.md, Observe and recover. */}
+
+## Recovery and operator requests
+
+Every recovery and operator `POST` carries a JSON body:
+
+- `cancel`, `reconcile`, `retry-same`, `restore-hold`, and `release-restore-hold` take a `Reason`,
+  whose `reason` is a bounded investigation reference of 1 to 256 characters without personal data,
+  such as `incident-2026-10-09`. The audit journal records a keyed `reasonRef`, never the reference.
+- `/v1/retention` takes a `Retention`: a `before` cutoff in the past and a `limit` of 1 to 100.
+  It answers how many payloads it `erased`.
+- `/v1/release-admission-hold` takes an `AdmissionRelease`: a `recoveryReference` and the two
+  attestations `admissionHistoryComplete` and `priorDeploymentFenced`. A false or omitted
+  attestation refuses the release.
+- `/v1/complete-execution-recovery` takes an `ExecutionRecovery`: a `recoveryReference` and the
+  attestations `executionHistoryComplete` and `priorDeploymentFenced`.
+
+The attestations are audited operator statements, not automated proof. A cancel answers the run's
+status, a reconcile its inspection, and a retry-same the run ID and its scheduled status.
+
+{/* Evidence: products/coordinator/generated/openapi/coordinator.openapi.json, Reason, Retention,
+    AdmissionRelease, ExecutionRecovery; products/coordinator/DEPLOYMENT.md, Admit and inspect
+    work and Backup and restore. */}
+
+These routes authenticate and authorize before they report a malformed body. A body is
+`application/json` or another application media type ending in `+json`; any other media type
+answers `415 request.unsupported-media-type`, after authorization. Bodies are bounded to 65,536
+bytes, and duplicate or unknown members are refused. An empty, overlong, or control-character
+reason answers `400 request.reason-invalid`, and an out-of-bounds cutoff or limit
+`400 request.retention-invalid`. State and recovery conflicts answer `409`.
+
+{/* Evidence: crates/registry-coordinator/src/http.rs, DefaultBodyLimit;
+    products/coordinator/DEPLOYMENT.md, Admit and inspect work. */}
+
+## Review completions
+
+`POST /v1/review-completions` takes Casework's completion events for a review producer connection.
+It authenticates the sender by the `Authorization: Bearer` completion token and the
+`Registry-Recipient-Binding` header together, comparing the token in constant time, and refuses
+any other sender with `401 authentication.refused` before reading the body. Without a configured
+`completion` block on the connection, it refuses every event.
+
+An authenticated event is `application/json` of at most 2048 bytes, with `type`, `eventId`,
+`requestId`, `resultId`, and `completedAt`. It repeats its `eventId` as the `Idempotency-Key`
+header, and its `completedAt` is no older than 365 days and no more than five minutes ahead of the
+Coordinator's clock. Anything else answers `400 request.invalid` or
+`415 request.unsupported-media-type`.
+
+Every authentic, well-formed event answers `204`, whether or not a run waits on its request. The
+event only brings forward the next result read of a run already waiting on that request: the run
+reads the result itself through the connection's producer credential. An event starts no run.
+`503 service.unavailable` asks Casework to deliver the event again.
+
+{/* Evidence: crates/registry-coordinator/src/completion.rs, receive_review_completion,
+    MAXIMUM_BODY_BYTES; products/coordinator/generated/openapi/coordinator.openapi.json,
+    ReviewCompletion; products/coordinator/DEPLOYMENT.md, Configure the deployment. */}
+
+## Problem documents and codes
+
+Every refusal, including a request refused before its route runs and a refused completion event, is
+an RFC 9457 `application/problem+json` document with `type`, `title`, `status`, `detail`, `code`,
+and `traceId`. The `type` is the code with its dot replaced by a slash under
+`https://id.registrystack.org/problems/registry-coordinator/`. The title and detail are fixed
+sentences that belong to the code, and no member repeats a submitted value. A refusal carries
+`Cache-Control: no-store` and a `traceparent` header whose trace matches `traceId`; a `401` also
+carries `WWW-Authenticate: Bearer`, and a `503` carries `Retry-After`.
+
+{/* Evidence: crates/registry-coordinator/src/problem.rs; products/coordinator/README.md, Observe
+    and recover; products/coordinator/generated/openapi/coordinator.openapi.json, Problem. */}
+
+Every problem response carries one `code` from this closed catalogue, answered with the HTTP status
+listed beside it. `request.not-found` answers a path the contract does not declare, and
+`request.unprocessable` a body the HTTP framework rejects before an operation reads it, so the
+operations page lists neither under an operation. `coordinatorctl` reports its own diagnostics
+with `coordinator.*` codes, which this catalogue does not hold.

+title: Registry Coordinator overview
+description: What Registry Coordinator runs for an authorized caller, the five step types a flow is built from, and what stays with each product a flow calls.
+status: draft

+source_repos:
+  - registry-stack
+last_reviewed: unreviewed

+locale: en
+standards_referenced: []
+---
+
+Registry Coordinator runs a reviewed, declared flow of calls to other Registry Stack products'
+public HTTP APIs, and keeps that flow going across durable waits, service outages, and worker
+restarts. Use it when a sequence such as "read the application, wait two days, read it again, then
+send a notice" has to continue without a person or a script holding it open. Each product a flow
+calls keeps authorization and ownership of what that call does.
+
+{/* Evidence: products/coordinator/README.md;
+    products/coordinator/PRODUCT-CONTRACT.md, Execution and authority. */}
+
+## What a flow is
+
+A flow is a finite, acyclic graph of steps written in YAML. Mappings carry values between steps,
+and bounded pure Rhai functions compute values and pick branches; a function cannot make a call or
+acquire a credential. You check a flow offline, test it against fake product replies, and package
+it into an immutable artifact an operator pins by digest. A run keeps the definition it was
+admitted under, so upgrading a flow never changes a run in flight.
+
+{/* Evidence: products/coordinator/PRODUCT-CONTRACT.md, Execution and authority;
+    crates/registry-coordinator/src/deployment.rs, package. */}
+
+Every step has one of five types:
+
+- `call` sends one of ten fixed operations over a connection the operator configured, such as
+  reading a Base Registry Engine (BReg) record, booking a Registry Scheduling appointment,
+  submitting a Registry Messaging message, or submitting a Registry Casework review request.
+- `choose` picks the next step from one value, such as a field of an earlier call's output.
+- `wait-until` waits until an instant. The wait is stored in PostgreSQL, so it survives a
+  restart.
+- `wait-for` waits, up to a timeout, for the result of a review request an earlier step submitted
+  to Casework. The run reads that result itself. Casework's completion event only brings the next
+  read forward.
+- `finish` ends the run with a declared outcome and output, which the caller reads from the run's
+  status.
+
+{/* Evidence: crates/registry-coordinator/src/authoring.rs, AuthoredStep;
+    crates/registry-coordinator/src/operations.rs, CATALOG;
+    products/coordinator/README.md, Waits and polling. */}
+
+No step leads back to an earlier one, so a poll is written out as a fixed number of rounds. The
+last round finishes with an outcome saying the answer is not there yet, and the caller decides
+whether to start a new run later.
+
+## When to use it
+
+Use the Coordinator when a sequence of product calls has to outlast time and failure: a follow-up
+after a delay, a notice once a human review approves, a booking after an approved deferral. It is
+an optional service with its own PostgreSQL 17 or newer database, where a run's progress and
+prepared commands are stored encrypted. A call is retried only after an answer the receiving
+product says it did not act on, and an uncertain effect waits for an operator rather than being
+sent again.
+
+Look elsewhere when the work needs SQL, arbitrary HTTP methods, a loop, or a number of calls known
+only at run time. The Coordinator has no SQL steps, no dynamic fan-out, no automatic compensation,
+and no distributed rollback.
+
+{/* Evidence: products/coordinator/README.md, Start from a maintained project;
+    products/coordinator/DEPLOYMENT.md, Recover safely. */}
+
+## What it never does
+
+- **It never starts a run from an event.** A run starts only when a caller asks, through
+  `POST /v1/runs` or `coordinatorctl start`. A completion event wakes a run already waiting on
+  that review request, and starts nothing.
+- **It never inherits authorization.** A caller allowed to start a run is not thereby allowed the
+  effects its flow requests. Each call uses the identity the operator configured for that
+  product's connection, acquired when the call is attempted, and the receiving product decides the
+  call under its own policy. A wait or a retry never renews an approval.
+- **It never writes to another product's database.** It reaches each product over that product's
+  public HTTP contract.
+- **It never rolls back.** Cancelling a run stops future calls where it can, and leaves every effect

+The Coordinator is pre-1.0, so use the binaries and documentation of one release together. The
+[reviewed notice example](https://github.com/registrystack/registry-stack/tree/main/products/coordinator/examples/reviewed-notice)
+shows a whole flow: it submits a Casework review, waits up to fourteen days, sends a notice on
+approval, and withdraws the request on timeout. A tutorial is tracked in
+[issue #1997](https://github.com/registrystack/registry-stack/issues/1997).

+- [Deploy Registry Coordinator](../../operate/coordinator/) to run the service against PostgreSQL

+
+This tutorial joins an application record, a human review, and an email without accepting a
+caller-supplied recipient. Coordinator reads registry-owned contact details from Base Registry
+Engine (BReg), stores its bounded run state encrypted, sends useful review facts to Casework, waits
+durably, then reads BReg again before it asks Messaging to send anything.

+/>
+
+## Build the local tools
+
+From the source checkout, build the eight product commands and the trusted input helper. The
+repository's pinned Rust toolchain and locked dependency graph select their exact versions. This
+uses the ordinary runtime features; the tutorial does not require test-only PostgreSQL support.
+
+```sh
+cargo build --locked \
+  -p registry-coordinator --example reviewed-notice-input \
+  -p registry-breg --features registry-breg/runtime \
+  -p registry-bregctl \
+  -p registry-casework \
+  -p registry-caseworkctl \
+  -p registry-messaging \
+  -p registry-messagingctl \
+  --bins
+```
+
+The helper finds these commands under `target/debug`. It uses OpenSSL to create short-lived local
+database certificates and Docker to run disposable PostgreSQL and Mailpit containers.
+
+## Start the four products
+
+From a Registry Stack source checkout, start the example-owned session. It uses `bregctl dev` for
+the shared local issuer and application registry, packages and applies Casework, Messaging, and
+Coordinator through their normal commands, and sends email to the version-pinned Mailpit SMTP
+sink. The helper creates only resources recorded under its session directory.
+
+```sh
+mkdir -p tutorial-work
+python3 products/coordinator/examples/reviewed-notice/session.py start \
+  --session-dir tutorial-work/reviewed-notice
+```
+
+The helper seeds one application, computes its reviewed projection digest with the maintained Rust
+review protocol, starts a `reviewed-notice` run, and waits until Casework owns the decision. It keeps
+credentials in owner-only files. Its status contains endpoint and file references, not secret
+values:
+
+The producer is trusted to prepare the review subject with the supplied helper. Coordinator checks
+the submitted BReg revision before it requests review, but it does not recompute the producer's
+projection digest.
+
+```sh
+python3 products/coordinator/examples/reviewed-notice/session.py status \
+  --session-dir tutorial-work/reviewed-notice \
+  > tutorial-work/session-status.json

+print('Run:', s['runId'])

+```
+
+```text
+Session: ready
+```
+
+Local access tokens expire. If a later request returns `401`, refresh the relevant header file
+with `cargo run --locked -p registry-bregctl --bin bregctl -- dev token CLIENT PROJECT`.
+Use `staff` for Casework or `coordinator-producer` for Coordinator as `CLIENT`, and the
+`ownerProject` path in `tutorial-work/session-status.json` as `PROJECT`. Then repeat the request.

-```sh
+~~~sh
 coordinatorctl check --project products/coordinator/examples/reviewed-notice --explain
 coordinatorctl test --project products/coordinator/examples/reviewed-notice
-```
-
-The run starts at once and has a `deadlineSeconds` of 2592000 (thirty days):
-
-1. `submit-review` submits one review request of kind `application-review` to
-   Casework as the review producer. The request names the application version
-   and digest under review and submits the only context a reviewer sees, the
-   application identifier and version, so Casework needs no source adapter.
-2. `await-review` waits for the result of that request for at most fourteen
-   days (`timeoutSeconds: 1209600`). Casework's completion event wakes the
-   run; the event carries no result and only prompts a read. The Coordinator
-   reads the result with the producer identity when the wait starts, on each
-   wake and every `resultCheckSeconds` (900 in the runtime template) as a
-   fallback, and keeps waiting while the review is open.
-3. `decide` chooses on the result's `status`. `approved` continues to
-   `notify`, `rejected` finishes with outcome `rejected`, and every other
-   settled status (`changes-requested`, `answered`, `cancelled` and
-   `superseded`) finishes with outcome `not-decided` and that status.
-4. `notify` submits one message with sender profile `transactional`, template
-   `application-approved` version `1` and locale `en` to the input `email`. The
-   message cites the review result by `resultId` and repeats none of its
-   content.
-5. `notice-sent` finishes with the Messaging `messageId` and the `resultId`.
-
-When the fourteen days pass without a settled result, `withdraw` cancels the
-review request in Casework and `confirm-withdrawal` chooses on the
-cancellation's `/outcome`. `cancelled` finishes with outcome `withdrawn` and
-the `resultId` Casework recorded for the cancellation. A reviewer can decide in
-the moment before the cancellation reaches Casework: the cancellation then
-reports `already-terminal` with that decision, and the run finishes with
-outcome `decided-late`, the decision's `status` and its `resultId`. The run
-sends no notice for a late decision; an operator reads the outcome and follows
-up in Casework. Any workflow that withdraws a review routes on the cancel
-step's `/outcome` the same way, since only `cancelled` means the withdrawal
-ended the review. A result that settles in the final read at the timeout wins
-over the timeout and continues at `decide`.
-
-The result a read returns must belong to the accepted request: the same
-request, subject, policy and submission digest. Any other result fails the run
-with `invalid-response`. An unknown request fails with
-`review-request-unknown` and an expired result with `review-result-expired`.
-Casework supersedes a request that is still under review when the same
-producer submits another for the same application and kind, whatever its
-version. Every run of this flow submits as producer `coordinator`, so a second
-run for the same application supersedes the first: the first run reads
-`superseded` and finishes `not-decided`, and the second run waits for the
-replacement review.
-
-The scenarios cover an approved review and its notice, a rejected review with
-no notice, a request for changes that is not a decision, a withdrawal after
-fourteen days without a decision, a decision recorded shortly before the
-withdrawal that finishes `decided-late`, and a notice refused after an
-approval. They use synthetic replies
-and review results only, so they do not prove Casework review policy, reviewer
-authority, completion delivery, Messaging policy or provider delivery.
-
-For a deployment, the institution must supply these prerequisites:
-
-- Casework declares review kind `application-review` version `1` with
-  `purpose: approval`, `contextStrategy: submitted` and a `displaySchema` that
-  accepts `applicationId` and `applicationVersion`. Its rejection and
-  change-request outcomes are Casework policy; the workflow reads only the
-  settled `status`.
-- Casework declares review producer `coordinator` for kind
-  `application-review` and source namespace `applications`, with the issuer and
-  subject of the Coordinator's Casework client and a `completion` block whose
-  `recipientBinding` is `coordinator-v1`.
-- Casework's runtime configuration lists that producer's completion
-  destination under `reviewCompletionDestinations`. Its `url` is the
-  Coordinator's `/v1/review-completions` route on the main listener and its
-  `bearerTokenRef` names the same secret as the Coordinator's
-  `completion.bearerTokenRef`. The Coordinator accepts only an
-  `Authorization: Bearer` header, so do not configure a custom header.
-- The token endpoint registers the `coordinator-review-producer` client for
-  resource `urn:example:casework` with scope `casework:review`, and the

+
+## Prepare trusted input
+
+The reviewed-notice-input Rust example reads the application through the
+maintained BReg client. It writes a new owner-only input file containing the
+real application identifier and revision. Its digest covers only the submitted
+review projection: applicantName, benefitProgram and requestedAmount.
+The helper uses registry_review_protocol::canonical_bytes and
+ContentDigest::for_bytes, the same bounded canonical JSON contract used by the
+review protocol.
+
+Build the helper with the same source and lockfile as Coordinator:
+
+~~~sh
+cargo build --locked -p registry-coordinator --example reviewed-notice-input
+~~~
+
+Give it an owner-only token file for a BReg profile that may read the
+application. A bregctl dev token header file is accepted directly:
+
+~~~sh
+target/debug/examples/reviewed-notice-input \
+  --breg-url http://127.0.0.1:8100 \
+  --record-id 00000000-0000-4000-8000-000000000001 \
+  --token-file ./private/application-reader.headers \
+  --output ./private/reviewed-notice-input.json
+~~~
+
+The command refuses an existing output path. Its JSON report names the output
+file without printing its application data or credential. Start the run with
+that file through coordinatorctl start.
+
+## Workflow decisions
+
+The run has a thirty-day deadline and follows these checks:
+
+1. read-for-review reads the application from BReg. If its identifier or
+   revision differs from the trusted input, the run finishes
+   application-changed without creating a review.
+2. submit-review sends the bounded facts to Casework as kind
+   application-review. Casework owns reviewer eligibility, policy and the
+   decision.
+3. await-review waits up to fourteen days. A Casework completion event wakes
+   the run, but the Coordinator still reads the result through the producer
+   connection before continuing.
+4. A rejection finishes review-rejected. Other terminal results that are not
+   approval finish review-not-approved.
+5. After approval, read-for-notice reads BReg again. Revoked noticeAllowed
+   finishes notice-permission-gone. Any other revision change finishes
+   application-changed.
+6. Only an unchanged reviewed revision with current notice permission reaches
+   notify. The recipient email comes from this second BReg read. A successful
+   Messaging receipt finishes notice-accepted.
+
+The workflow therefore sends no notice for a rejection, an application change
+or revoked notice permission. Messaging can still refuse an otherwise eligible
+notice under its own current policy; that product refusal stops the run without
+claiming an accepted notice.
+
+## Withdrawal and late decisions
+
+When fourteen days pass without a result, withdraw-timeout cancels the review.
+An operator cancelling a run parked at the review wait takes the separate
+withdraw-operator route. Casework receives a distinct recorded reason and the
+run finishes review-timeout-withdrawn or review-operator-withdrawn.
+
+A reviewer may decide immediately before either cancellation reaches Casework.
+In that race the cancellation reports already-terminal; both routes finish
+decided-late with Casework's status and result identifier. They do not send a
+notice. Only a cancelled response proves that Casework closed the open review.
+
+## Deployment prerequisites
+
+The institution supplies these independent authorities:
+
+- BReg exposes applications to the configured follow-up-reader service profile,
+  including the reviewed facts, email and noticeAllowed.
+- Casework declares submitted-context review kind application-review version 1.
+  Its display schema accepts applicantName, benefitProgram and requestedAmount.
+- Casework admits producer coordinator through profile coordinator-producer,
+  and its completion destination uses the same bearer secret and recipient
+  binding as the Coordinator connection.
+- Messaging permits sender profile transactional, template
+  application-approved version 1 and locale en for its own service caller.
+- The token endpoint registers separate BReg reader, Casework producer,
+  Messaging sender and Coordinator caller identities. Starting a run grants
+  none of those product permissions.
+
+The runtime template contains HTTPS reference endpoints and secret references.
+Copy it outside the package and adapt its endpoints, database identity, client
+registrations, completion secret and package digest. Follow the
+[deployment runbook](../../DEPLOYMENT.md) for packaging, activation and
+recovery.
