Design constraint + +Every tool visible to a model is an RSS-owned component. + +RSS owns: + +- public tool name and description; +- JSON Schema presented to the provider; +- registry order and enablement; +- argument validation and defaults; +- dispatch by public tool name; +- tool-specific algorithms and result formatting; +- tool-specific error mapping; +- composition of one or more native capabilities. + +Rust owns only generic capabilities and runtime invariants that cannot safely depend on script cooperation. + +Rust must not contain: + +- a built-in list of model-visible tool names; +- model-visible tool descriptions or JSON Schemas; +- an enum with variants such as `ReadFile`, `Patch`, or `Terminal`; +- dispatch branches keyed by public tool names; +- tool-specific argument parsing or response formatting. + +This boundary applies to current tools and future tools. Adding a model-visible tool must normally require an RSS change and tests, with no Rust registry change. + +## 2. Current mismatch + +The current implementation places the six public tools in `src/tools/*`: + +- `registry.rs` owns the built-in ordering, schemas, risk classes and native executor mapping; +- `dispatch.rs` validates public arguments, selects `NativeToolExecutor`, manages execution and shapes `ToolResult`; +- `files.rs`, `terminal.rs` and `process.rs` contain model-visible behavior; +- `rss/agent/main.rss` delegates each call to `agent::tool_dispatch`. + +That structure makes RSS the loop coordinator while Rust remains the actual tool platform.

It then calls: + +```text +agent_runtime::tool_prepare(metadata) -> map +``` + +Metadata contains: + +- run ID; +- call ID; +- opaque public tool name; +- canonical argument digest; +- descriptor/registry identity; +- RSS risk classification; +- bounded sanitized summary. + +Rust treats the name as opaque data. `tool_prepare` performs generic checks: + +1. run and parent are active; +2. call ID/name match the durable assistant parent; +3. canonical terminal result is replayed when present; +4. run/tool-call limits permit another call; +5. approval policy permits execution; +6. `tool.started` is committed durably before capability access; +7. a scoped execution token is issued. + +Return shape: + +```json +{ + "kind": "execute", + "execution_token": "opaque", + "deadline_ms": 0 +} +``` + +or: + +```json +{ + "kind": "replay", + "result": {} +} +``` + +### 4.2 Capability use + +Each execution token is bound to: + +- profile/session/run/call identity; +- frozen workspace directory capability; +- absolute deadline and cancellation token; +- approved risk ceiling; +- output/artifact budgets; +- process ownership; +- lifecycle generation. + +A token cannot be reused by another call or after terminal commit. Native capability functions validate the token before every effect. RSS cannot mint or modify one. + +One tool may invoke multiple capabilities. This supports RSS implementations such as `patch`: bounded read, RSS transformation, atomic compare-and-write. + +### 4.3 Completion + +RSS normalizes and bounds the result, then calls: + +```text +agent_runtime::tool_commit(execution_token, result) -> map +``` + +Rust validates token ownership, commits the durable tool result and terminal tool event, closes the execution token, and returns the committed envelope. + +If RSS terminates or panics with an open token, RAII cleanup marks the execution interrupted, cancels owned processes and prevents token reuse. Recovery never repeats an execution that has a canonical durable terminal result. + +## 5. Tool algorithms in RSS + +### 5.1 `read_file` + +RSS validates path, offset and limit; it calls bounded read capability and adds line numbers and pagination metadata. Rust performs path confinement and byte I/O only. + +### 5.2 `search_files` + +RSS owns glob/regex options, pagination, ordering and output formatting. Rust exposes bounded directory iteration and bounded file reads. If performance later requires a native search iterator, it must remain a generic workspace search capability with no model-facing schema or formatting. + +### 5.3 `write_file` + +RSS validates input, reads current metadata/hash when needed and requests atomic replacement. Rust enforces root confinement, expected-hash compare, file mode policy and atomic write mechanics. + +### 5.4 `patch` + +RSS parses replacement/patch input, computes candidate content, checks uniqueness and formats a diff preview/result. Rust only supplies bounded read and atomic compare-and-write. No patch grammar or fuzzy-match strategy remains in Rust. + +### 5.5 `terminal` + +RSS validates command, cwd and user-facing options, then maps them to `cap::process_spawn`. Rust owns process-group creation, environment allowlist, cwd capability, time/output limits and cancellation. + +### 5.6 `process` + +RSS maps public actions to process capability operations and formats logs/status. Rust owns opaque process resources, authorization, bounded buffers, stdin/kill mechanics and cleanup. + +## 6. Registry snapshot and provider contract + +At run admission, Rust invokes the exported RSS registry function using the admitted agent source and non-secret tool policy. The returned descriptor array is: + +1. structurally bounded by Rust; +2. canonicalized deterministically; +3. hashed; +4. stored in the run context as the frozen provider-facing registry snapshot. + +Rust verifies generic limits for count, names, description bytes, schema bytes/depth and duplicate names. It does not supply built-in names, descriptions or schemas. + +The frozen snapshot is sent to every provider request for that run. Resume recompiles/loads the same RSS source and verifies registry identity before continuing. A changed registry requires a new run or an explicit migration contract. + +## 7. Approval boundary + +RSS assigns the requested risk class in each descriptor. Rust policy maps the frozen descriptor identity and risk class to allow/ask/deny. + +Approval records bind: + +- run/call ID; +- registry identity; +- canonical argument digest; +- requested risk class; +- expiry. + +RSS cannot lower risk after approval because `tool_prepare` compares the requested metadata with the frozen descriptor. A capability also checks that its native operation does not exceed the approved ceiling. For example, a read-approved token cannot call a write or process capability. + +## 8. Failure and recovery behavior + +- Invalid RSS arguments fail before `tool_prepare`; no durable started state or native effect occurs. +- A failed durable started commit returns a terminal dispatch error and no execution token. +- A capability error is converted by the RSS tool module into its public error contract, then committed once. +- A failed result commit after a native effect closes the execution token and fails the run; the capability is not repeated in-process. +- Restart inspects durable lifecycle state. Completed/failed/interrupted results replay. An execution left open at process death becomes interrupted through recovery policy and does not automatically repeat mutating effects. +- Process handles are run/call-owned and are cancelled during stop, deadline, source failure or gateway recovery. + +## 9. Security properties + +- Workspace authority originates in Rust admission, never in RSS strings. +- Every path capability resolves beneath the frozen root and resists symlink replacement. +- Every process starts in an authorized cwd with bounded environment, duration and output. +- RSS receives opaque handles/tokens only. +- RSS cannot call capabilities before durable preparation or after completion. +- Capability errors expose bounded neutral messages and no host absolute paths outside the workspace. +- Tool output/artifacts pass through existing secret redaction and byte caps before persistence/publication. +- Generic pd-vm host APIs that bypass these checks are omitted from the production agent catalog. + +## 10. Migration sequence + +1. Add RSS tool contract tests and generic capability interfaces while retaining old dispatch behind a test-only comparison path. +2. Move registry descriptors, ordering, schema validation and fingerprint source into RSS. +3. Implement lifecycle execution tokens and capability risk classes. +4. Migrate read-only file tools and compare exact fixture envelopes. +5. Migrate write/patch tools with atomic compare-and-write tests. +6. Migrate terminal/process tools with process ownership and restart tests. +7. Switch `rss/agent/main.rss` from `agent::tool_dispatch` to `tools::dispatch`. +8. Remove `NativeToolExecutor`, built-in registry entries and public tool-name branches from Rust. +9. Rename surviving generic modules from `tools` to `capabilities`. +10. Run full agent, gateway, Telegram, debug and release gates. + +No compatibility shim remains in production after migration. Durable data compatibility is preserved because public tool names, call IDs, result roles and event contracts remain unchanged. + +## 11. Test contract + +### RSS tests + +- descriptors and schemas for all six tools; +- deterministic registry identity; +- validation defaults and failures; +- dispatch routing; +- exact result envelopes; +- patch/search algorithms; +- terminal/process action mapping; +- provider tool-call to tool-result loop. + +### Rust capability tests + +- token ownership and single-close behavior; +- workspace confinement and symlink races; +- atomic compare-and-write; +- process group cancellation and output caps; +- approval ceiling enforcement; +- durable-before-effect preparation; +- replay and interrupted recovery; +- panic/unwind cleanup. + +### Architecture tests + +- Rust production source contains no built-in public tool registry. +- `src/capabilities` contains no public tool description/schema fixtures. +- `rss/tools` contains all model-visible descriptors. +- adding a fixture-only RSS tool requires no Rust enum/dispatch edit. +- production host catalog excludes unrestricted pd-vm file/process APIs. + +### End-to-end tests + +- real RSS agent loop executes every tool through generic capabilities; +- gateway restart replays canonical tool results without duplicate effects; +- stop/deadline cancels open process capabilities; +- approval blocks capabilities before effect; +- toolset snapshot remains identical across reopen; +- Telegram/API output remains compatible. + +## 12. Acceptance criteria + +1. Every model-visible tool is defined and implemented in `rss/tools`. +2. `rss/agent/main.rss` contains no call to `agent::tool_dispatch`. +3. Rust has no `NativeToolExecutor` or built-in public tool order. +4. Rust exposes generic capabilities and durable lifecycle functions only. +5. Workspace, process, approval, output and cancellation safeguards remain native and mandatory. +6. Existing public tool names and durable message/event contracts remain compatible. +7. A new RSS-only tool can be registered without editing Rust dispatch code. +8. Full locked debug and release suites pass from the final migration commit. diff --git a/plans/2026-08-25_coding-tools-registry-agent-loop.md b/plans/2026-08-25_coding-tools-registry-agent-loop.md new file mode 100644 index 0000000..d7a31fc --- /dev/null +++ b/plans/2026-08-25_coding-tools-registry-agent-loop.md @@ -0,0 +1,268 @@ +# Coding Tools, Registry, Dispatch, and Agent Loop Implementation Plan + +**Goal:** 完成 `rustscript-agent` 首个可实际修改代码并运行验证命令的 serial coding agent 闭环。 + +**Architecture:** RSS 继续拥有 serial agent policy 与 provider protocol mapping；native Rust embedding 拥有工具注册、权限、OS effects、事件提交和 durable state。`RunContext.tool_schemas` 从 registry 快照生成，RSS loop 依次执行 provider call、tool dispatch、tool-result message 回填和下一轮 provider call，最终由 `AgentService` 提交 terminal state。 + +**Tech Stack:** Rust 2024、RustScript RSS、Axum/Tokio、SQLite durable store、OpenAI Chat adapter、RustScript custom host extensions、RustScript core bounded process/filesystem APIs。 + +--- + +## 1.

Mandatory RSS-first boundary for Task 1 and every later task + +This section is normative. It takes precedence over conflicting language, file lists, examples, and implementation steps elsewhere in this plan. It applies retroactively to Task 1 and to all in-progress and future Task 2+ work. + +- RSS is the primary implementation layer for agent business behavior: provider selection and adaptation, authentication/login/refresh workflow orchestration, retry and polling policy, model request/response shaping, session/workspace policy, approvals, compaction decisions, and user-facing business error mapping. +- Rust supplies only necessary generic foundational capabilities and their security enforcement: bounded parsing/typed transport, filesystem confinement and permissions, cross-process locking, atomic persistence, generation compare-and-swap, cryptographic/PKCE primitives, bounded HTTP transport, callback listener mechanics, clock/cancellation, and secret-handle access. Rust may enforce mandatory trust boundaries; it must not become a parallel business workflow engine. +- Provider-specific endpoints/defaults, protocol payload interpretation and workflow decisions belong in RSS/provider adapters. Trusted authority validation may remain a generic Rust mechanism driven by trusted policy/configuration, without granting RSS permission to substitute an unauthorized authority. Secrets must remain confined to host-side storage/transport and opaque handles; RSS-first does not permit exposing raw credentials to model context, durable events, or logs. +- Structural data declarations may remain in Rust when they define bounded YAML/JSON shapes, typed transport envelopes, persistence records, or capability handles. Rust loaders validate types, sizes, key separation, generic URL syntax and trusted authority constraints; RSS interprets provider fields, state labels, defaults, selection and business errors. Do not duplicate or relocate generic declarations solely to satisfy an ownership label. +- Task 1 schema/loaders and Task 2 secure storage are permissible Rust foundations only to the extent that they implement data integrity, resource bounds, persistence and capability enforcement. Provider business rules, provider-name branches, refresh timing, login decisions and business error mapping embedded in those modules require migration to RSS or a separately justified generic security contract. +- Every Task 1+ implementation and review must enumerate RSS-owned behavior, necessary Rust primitives, the host bridge contract, and real RSS entry-path verification. A Rust-heavy task file list is not permission to move business behavior into Rust. Amend conflicting later task instructions before their implementation is accepted. +- Every real provider/auth/runtime path must use the opaque-provider bridge described in section 1B. Existing RSS `api_key` maps and direct RSS `http::*` calls for provider authentication are migration blockers; they cannot be retained as a parallel path. +- Re-review the integrated Task 1 implementation, the current Task 2 scope, and every remaining task against this boundary. Earlier review results do not establish compliance with this clarified requirement. Block further integration of Task 1+ changes until the boundary review and any required corrections pass; preserve existing commits and work in progress. + +### 0.1 Boundary review evidence and current acceptance status + +The completed review is preserved at: + +```text +/mnt/TEMP/workspace/rustscript-agent/tmp/prod-agent-rss-boundary-review-84988318/rss-first-boundary-review.md +``` + +It records: + +- plan snapshot `9a5cf3a0ddcfb148228d72fffebae08a177c6f52`; +- integrated Task 1 commit `1c0b8dfd8aaac82552adf66cf0dee114f0af4e8f`; +- `passed=false` for both normative compliance and quality acceptance; +- Task 1 Rust-only loader/schema coverage with no real RSS entry or host-bridge verification; +- Codex-specific endpoint/default/authority logic in Rust and an existing RSS `api_key` flow that violates the opaque-credential boundary; +- Task 2–13 file lists and acceptance descriptions that did not consistently name RSS owners, bridge contracts or RSS entry tests. + +The existing integration commit is retained. Task 1 acceptance is **reopened for the boundary address**. Task 2 acceptance is **unaccepted** until its interrupted snapshot has been reviewed and the revised boundary is verified. + +### 0.2 Explicit staged correction order + +The following stages are mandatory and intentionally separate foundation work from later provider/runtime behavior: + +1. **Stage A — integrated Task 1 boundary address.** Address the existing Task 1 integration on top of `1c0b8df` without reverting it. Remove provider-name/default/business branches from the generic loader, keep structural schema/resource/security checks, and add a minimal real RSS config/auth entry plus a fixture host bridge. This entry exercises only structural snapshot and opaque-reference handling; it must not require Task 2 storage, OAuth networking, Codex login, or authenticated model runtime. Task 1 remains reopened until this focused gate passes. +2. **Stage B — interrupted Task 2 snapshot review.** The Task 2 owner/parent must freeze an immutable `StageBSnapshotRecord` before any review or continuation. The record must include the exact parent/base commits, worktree/branch, capture time, content-addressed snapshot ID, tracked and untracked file inventories with byte sizes/modes/SHA-256 hashes, and hashes of the tracked diff plus every untracked-file artifact; it must inventory all tracked and untracked regular files in the worktree without silently omitting ignored/generated files. The parent supplies the record and artifacts before review; this plan revision does not invent a snapshot ID/hash or inspect a live Task 2 worktree. The gate is **unavailable** until the record is frozen and immutable. Review the frozen exact diff, file ownership, raw-secret flow, Rust provider semantics and test scope against section 0; Task 2 remains unaccepted during and after any review that lacks a frozen record. After a passing verdict, continue only with generic store primitives, generation/CAS and the minimal RSS store entry; do not require future OAuth or provider-runtime functionality from this foundation step. +3. **Stage C — opaque-provider bridge migration, then a separate provider-loop gate.** First pass `C-MIGRATION`: migrate the existing RSS provider bridge (`rss/providers/profile.rss`, `rss/llm/types.rss`, `rss/llm/openai_chat.rss` and related provider adapters) from raw `api_key` maps to the section 1B opaque handle contract, add forged/copy/replay/serialization and negative secret-flow tests, and remove direct provider Authorization assembly from RSS. This gate uses only a fixture host and synthetic opaque handles; it does not make a live provider request. After `C-MIGRATION` passes, pass `C-PROVIDER-LOOP`: run the real RSS provider loop against a fake provider/host with fixture-only synthetic credentials to prove refresh/401/429/idempotency behavior. A fake-host loop is still not live/authenticated runtime and cannot authorize operator credentials. Task 3–6 may build either fixture surface; no live provider runtime or Task 8 acceptance may proceed until both gates pass. +4. **Stage D — later RSS-owned runtime behavior.** Continue provider runtime, Codex Responses, bundled source policy, workspace/session policy, approvals and compaction only after their individual RSS entry gates pass. Each stage may consume a prior generic primitive through the bridge, yet may not move its business policy into Rust for convenience. + +--- + +## 1.

Normative RSS ↔ Rust host bridge contract + +This contract applies to config/auth, OAuth, provider runtime, workspace, approval and compaction. It is separate from business policy and must be usable by a minimal fixture host before the later features exist. + +**Data classes:** + +- **Structural values:** bounded typed maps/records for YAML, JSON, request envelopes and durable records. Rust may declare and validate these shapes; RSS assigns provider/business meaning. +- **Sanitized provider data:** status, bounded public headers, bounded non-secret body fields, retry timing, expiry numbers, public account metadata and typed error facts after secret fields are removed. RSS may interpret these values. +- **Opaque handles:** non-forgeable host-issued references tied to a credential, provider policy, callback session, generation, run or capability token. RSS may pass handles back to the host, yet cannot inspect, forge, mint a distinct authority, or turn them into raw secret strings. A VM copy aliases the same host entry and never creates a new capability. + +**Trusted policy source, admission and ceilings (normative):** + +The single policy source for this bridge is a host-owned `TrustedPolicySnapshot`. The host creates it during `config::load_snapshot(host_home)` from operator-authored `config.yaml` entries that pass generic validation, together with immutable deployment/host ceilings. `config.yaml` is an operator control-plane input at host admission; RSS code, model output, user/run payloads and provider responses are untrusted data and cannot create, widen or replace a policy entry. This distinction does not ban explicit custom providers: an operator may declare a named custom provider in `config.yaml`, and the host may admit its explicit HTTPS authority/path/header policy when it satisfies the same generic bounds and deployment ceilings. An unknown provider name is not rejected merely because it is unknown; an entry is rejected only for failed validation, trust admission or a ceiling violation. + +`TrustedPolicySnapshot` is immutable for one `policy_generation` and contains the admitted provider authority/path-prefix and public-header allowlists/defaults, canonical workspace roots, maximum approval/risk ceiling, resource ceilings and the bounded public selection data RSS needs. The same host admission source supplies all four security-sensitive ceilings: provider authority/path/header permissions, workspace roots, approval ceiling and native resource limits. RSS can select an admitted entry or request a lower-risk operation, but it cannot add a root, authority, path, header value, risk class or resource limit. + +At snapshot/admission time the host injects an `OpaquePolicyHandle` into the RSS entry context; RSS has no constructor for this type and cannot replace, parse, stringify or serialize it. Every bridge call checks the exact handle, its frozen `policy_generation`, command/run scope, operation class, finite deadline and revocation state. A config reload publishes the next generation and rejects an old handle for new admissions. An already admitted run may finish against its immutable old snapshot until its run deadline, cancellation or explicit revoke; reload never widens that run's authority. Any explicit revoke, scope mismatch, stale generation or expired handle fails closed with a typed policy error and performs no native effect. + +The operator-config trust rule applies only at host admission. Values arriving later from RSS, model output, user requests, provider responses or durable replay are untrusted even when they resemble operator configuration. The host therefore injects policy handles rather than accepting policy IDs, URLs or ceilings from those values. + +**Canonical bridge signatures and envelopes (normative):** + +All later sections use these names and ownership rules; no `oauth::load_metadata`, `oauth::status` or parameterless `config::load_snapshot` variant exists: + +```text +config::load_snapshot(host_home: HostHome) -> ConfigSnapshotEnvelope { + public_config: BoundedPublicConfig, + credential_refs: BoundedCredentialRefs, + policy_handle: OpaquePolicyHandle, + policy_generation: PolicyGeneration, + policy_summary: SanitizedPolicySummary, +} + +auth::load_metadata( + credential_id: CredentialId, + policy_handle: OpaquePolicyHandle, +) -> AuthMetadataEnvelope + +auth::access_handle( + credential_id: CredentialId, + expected_generation: CredentialGeneration, + policy_handle: OpaquePolicyHandle, +) -> AccessHandleEnvelope + +auth::refresh_handle( + credential_id: CredentialId, + expected_generation: CredentialGeneration, + policy_handle: OpaquePolicyHandle, +) -> RefreshHandleEnvelope + +oauth::pkce_begin( + policy_handle: OpaquePolicyHandle, + public_intent: BoundedPublicOAuthIntent, +) -> PkceBeginEnvelope + +oauth::callback_wait(callback_handle: OpaqueCallbackHandle) -> CallbackEnvelope +oauth::transport( + request: ProviderRequest, + credential_use: OpaqueCredentialUse, +) -> SanitizedProviderResponse +auth::save_if_generation(request: SaveCredentialRequest) -> AuthMetadataEnvelope +auth::delete( + credential_id: CredentialId, + policy_handle: OpaquePolicyHandle, +) -> RedactedMutationResult +workspace::open( + selection: BoundedWorkspaceSelection, + policy_handle: OpaquePolicyHandle, +) -> WorkspaceOpenEnvelope +lifecycle::tool_prepare(request: ToolPrepareRequest) -> PrepareResult +lifecycle::tool_commit(request: ToolCommitRequest) -> CommitResult +``` + +`host_home` is resolved and bounded by the Rust CLI/gateway host before RSS runs; RSS and model/user inputs cannot supply or override it.

The VM marshaller must reject string conversion, reflection that exposes contents, hashing into a new authority, generic snapshotting and durable serialization with `opaque_nonserializable`; logs/events/errors record only the handle class and typed outcome. Host revocation removes the live entry and may best-effort clear host-owned transient buffers, yet the contract makes no impossible claim that every allocator or VM memory copy can be erased.

The host uses only the explicit `credential_use` argument; `ProviderRequest` has no credential field and cannot smuggle a second handle. RSS may choose a provider path and payload only through a policy handle obtained from trusted configuration. Rust resolves and enforces the authorized authority, optional path prefix and security-sensitive header policy; an RSS or user-supplied URL, `Host`, `Authorization`, cookie or authority cannot replace it.

RSS owns the operation sequence and request payload semantics. Rust resolves the authorized authority and any allowed path/header policy from trusted configuration, enforces HTTPS/loopback rules, caps body/response sizes and rejects arbitrary URLs, methods outside the generic allowlist, `Authorization`, cookies and user-supplied security-sensitive headers. There are no Rust branches for `device_start`, `device_poll`, `token_exchange`, `refresh` or any other provider workflow operation. + +The host enforces: + +- HTTPS remote endpoint and configured trusted authority/path policy. +- bounded request/response body, JSON depth/key/string limits and deadline. +- cancellation propagated from the owning CLI/run. +- redaction of token-shaped response fields in logs and errors. +- no durable event publication for raw OAuth payloads. +- provenance and lifetime checks for every opaque handle/secret slot. + +A token response is returned as sanitized public fields plus opaque secret slots. RSS may decide whether a response is a successful token set, which fields are required, how `expires_in` maps to policy, and what business error to show. `auth::save_if_generation(request)` accepts only slots from the active in-memory bridge session, checks their expected structural labels and generation, and persists their raw contents inside `AuthStore`; RSS never receives those contents. + +`auth::access_handle(credential_id, expected_generation, policy_handle)` returns only an opaque access handle and redacted metadata to RSS. The host uses the handle to assemble the Authorization header at the final transport boundary, then drops the token-bearing transport profile. `auth::refresh_handle` follows the same path and is never convertible to an access-token string in RSS. + +### 3.3 Generic authorization-code OAuth primitives + +RSS/provider adapters implement the reusable Authorization Code + PKCE workflow using the bridge. Rust supplies the following primitives and security checks: + +1. Generate cryptographically random verifier and state and retain them behind opaque handles. +2. Build/validate a bounded authorization URL from public parameters plus trusted provider policy; RSS chooses scopes and provider-specific public parameters. +3. Bind a random loopback port on `127.0.0.1` and accept one bounded callback. +4. Open the browser when available through the injected opener. +5. Validate exact state and single-use callback session in the host. +6. Exchange an opaque authorization-code handle through bounded transport with the opaque verifier; RSS owns the provider request sequence and response interpretation. +7. Persist validated token slots through `AuthStore` after RSS requests the save operation. +8. On SSH/headless systems, print the URL and accept a pasted callback URL/code through the CLI without weakening state/PKCE checks; the raw code remains host-side. +9. Cancel and remove all transient state on timeout, Ctrl-C or callback error. + +Generic flow configuration supports provider-specific scopes and additional public authorization parameters through a strict allowlist. Client secrets are outside the initial public-client scope. RSS decides when to start, poll, exchange, retry or report; Rust enforces callback, PKCE, authority, size and cancellation boundaries. + +### 3.4 Generic refresh primitives + +RSS owns token refresh eligibility, timing, workflow, retry, status classification and user-facing policy for every provider. Rust supplies locked metadata/handle access, host-side refresh-token use, bounded transport and atomic persistence: + +1. RSS reads metadata and decides whether the access token remains valid beyond configured `refresh_skew_seconds`; Rust returns only redacted metadata/opaque handles. +2. Rust serializes refresh per credential ID and re-reads after acquiring the lock. +3. RSS calls `auth::refresh_handle(credential_id, expected_generation, policy_handle)` and requests a refresh transport using the returned opaque refresh handle; Rust posts the generic `grant_type=refresh_token` form with the current raw refresh token only at the final host boundary. +4. RSS interprets the bounded response and decides whether a new access token is required; Rust enforces token-slot provenance and bounded fields. +5. RSS decides the expiry policy from sanitized `expires_in`; Rust applies bounded clock arithmetic and persists the selected metadata. +6. Rust preserves the old refresh token when the response omits one and atomically replaces it when a rotated opaque slot is supplied. +7. RSS classifies `invalid_grant`, `invalid_token`, HTTP 401/403 and provider-consumed refresh tokens as `reauth_required` according to provider policy. +8. RSS classifies 429 using bounded `Retry-After`; Rust preserves active credential state and returns a typed quota/transport fact. +9. RSS decides retry limits and backoff for timeout/5xx; Rust returns bounded typed transport errors and never overwrites a valid credential with a partial response. +10. Rust compares the observed generation before commit and re-reads under the auth lock. Two gateway processes racing a single-use refresh token converge on the newer generation; the later process adopts it rather than replaying the old refresh token. + +The refresh handle is valid only for that authorized single-flight transaction. Host-side envelope/policy validation that prevents the final request from starting returns a non-consuming typed error and allows one documented retry within the handle TTL after RSS corrects the public request. Once the final transport starts, the handle is consumed even when the result is an error or ambiguous timeout; RSS must reload metadata and generation before any new attempt. A generation mismatch is fail-closed and never sends the stale refresh token. + +This keeps CAS/locks/fsync and raw token persistence in Rust while keeping refresh workflow and policy in RSS. + +--- + +## 4. RSS Codex device login + +Create: + +```text +rss/auth/codex_device.rss +rss/auth/types.rss +``` + +The Codex-specific state machine remains in RSS and uses only the generic bridge. Provider paths, payload interpretation, pending policy, interval and business error mapping remain in this adapter. Device auth ID, authorization code and PKCE verifier are host-side opaque values; the RSS state machine retains handles only. + +### 4.1 State sequence + +1. Obtain the trusted provider-policy handle and call the bridge with the public device-start payload containing `client_id`. +2. Parse bounded sanitized fields: `user_code`, `interval` and an opaque device-session handle. Reject missing, wrong-type or oversized fields. +3. Emit a sanitized CLI instruction containing `https://auth.openai.com/codex/device` and the user code. The device auth ID remains host-side and is never rendered. +4. Poll through the bridge with the opaque device-session handle and user code until authorization, cancellation or a 15-minute absolute deadline. +5. Treat HTTP 403/404 as pending for this provider. +6. Honor configured minimum interval and bounded 429 `Retry-After`; RSS prevents tight polling. +7. On success, receive opaque authorization-code and verifier handles plus sanitized response metadata. +8. Call the bridge for token exchange using those handles, the configured public redirect URI and RSS-selected provider payload. +9. Call `auth::save_if_generation(request)` with opaque secret slots; report only redacted credential metadata. +10. Clear all transient RSS handles and request state before return on success, rejection, cancellation or timeout; the host invalidates its corresponding handles. + +### 4.2 Required RSS tests + +Use a fake native OAuth host and fixture responses to cover: + +- real `codex_device::login` RSS entry and exact bridge operation order. +- happy path and exact operation order. +- pending 403/404 followed by success. +- 429 backoff and absolute 15-minute deadline. +- cancellation during wait. +- malformed start, poll and exchange responses. +- exchange with missing access token slot. +- refresh token present/absent in initial exchange. +- no raw token/device auth ID/authorization code/verifier in events, snapshots or rendered output. +- no direct `http::*` call and no hard-coded credential persistence in the RSS module. + +--- + +## 5. CLI auth and config UX + +Refactor the current single-purpose argument parser without breaking legacy invocation. The Rust CLI remains a thin shell for argv, home, TTY/browser/cancellation and process exit mapping.

Rust must not select a provider or decide a login/refresh business outcome. + +**Bridge contract:** CLI passes a bounded command envelope and the host-resolved `host_home` to RSS. RSS calls `config::load_snapshot(host_home)`, `auth::load_metadata(credential_id, policy_handle)`, the canonical `oauth::*` calls and `auth::delete`; the host writes/removes raw credentials atomically and returns only sanitized metadata. `config check` may report missing/disabled/reauth-required labels from RSS interpretation while Rust enforces structural references and secret redaction. + +CLI acceptance criteria: + +- Login writes only `auth.yaml`; provider/model/source selection writes only `config.yaml`. +- Status output never prints token prefixes or lengths. +- Logout removes one named credential atomically and leaves unrelated credentials unchanged. +- `config check` validates config/auth references and reports missing, disabled or reauth-required credentials without printing secrets. +- Device login works over SSH without trying to bind a publicly reachable callback. +- Ctrl-C exits with a typed cancellation and leaves no partial credential entry. +- Subprocess tests invoke the real RSS command entry with an injected/fake host bridge; no live provider is required for the foundation gate. + +--- + +## 6. Runtime provider integration + +### 6.1 Credential resolution + +At run admission, RSS freezes the selected provider, credential ID and provider configuration hash as non-secret logical inputs. Immediately before each real provider request: + +1. RSS resolves provider/model selection and the named credential reference through the sanitized config/auth bridge. +2. RSS decides whether refresh is needed and, if so, obtains `auth::refresh_handle(credential_id, expected_generation, policy_handle)`, runs the provider-specific refresh policy through `oauth::transport(request, credential_use)`, and saves any rotated slots through `auth::save_if_generation(request)`. +3. The host returns an opaque access handle and sanitized provider metadata. +4. RSS/provider adapter builds the request body, path, public protocol headers and retry decision. +5. Rust validates the trusted provider policy, assembles the Authorization header at the final transport boundary, executes bounded transport and drops the token-bearing profile after the call. + +There is no Rust `AuthManager` workflow deciding refresh or provider behavior. `src/service.rs` and `src/runtime/rss_runner.rs` only preserve generic admission, cancellation, durable redaction and bridge invocation boundaries. + +Do not put access/refresh tokens in: + +- `RunContext` or its SQLite JSON. +- provider fingerprint input. +- `model.requested` / `model.completed` event payloads. +- assistant/tool messages. +- metrics labels. +- artifact files. +- panic/error strings. + +The durable provider fingerprint uses model, protocol, sanitized provider options and canonical messages. Credential ID and token generation are excluded so a refresh does not change logical request identity. + +### 6.2 Codex Responses transport + +Implement the Codex inference path required by the new login: + +```text +rss/llm/openai_responses.rss +rss/llm/harness.rss +rss/agent/provider_runtime.rss +src/runtime/rss_runner.rs +``` + +**RSS owner:** `rss/llm/openai_responses.rss` defines Codex request/response/stream shaping, provider parser, protocol header intent, provider error semantics and the one-shot retry decision. `rss/llm/harness.rss` and `rss/agent/provider_runtime.rss` drive the real RSS agent entry and durable turn policy. + +**Necessary Rust primitives:** bounded request/response transport, cancellation, deadline, trusted authority/path policy, opaque credential use, final Authorization assembly, host-only sanitized metadata and durable event redaction. Rust does not parse Codex payload semantics or choose 401/429 retry behavior. + +**Bridge contract:** RSS passes a policy handle, provider path, public request body and opaque access handle. Host returns a `SanitizedProviderResponse`; secret slots never enter RSS. If the Codex transport requires `ChatGPT-Account-ID`, the host may return the sanitized metadata envelope defined by the Task 8-only gate below; this plan does not assert an unverified provider claim/source. RSS may request the named header intent but cannot supply the metadata value or override trusted security-sensitive headers. `originator` and `User-Agent` are policy-selected header intents, while the host applies only policy-approved values and rejects arbitrary security-header overrides. + +### 6.2.1 Task 8-only Codex sanitized metadata decision gate + +This is an additional **Task 8-only** blocker. It does not reopen Stage A, change the frozen Stage B requirement, or block Stage C fixture construction. Task 8 acceptance and any live Codex-provider claim remain unavailable until this contract is decided with verified evidence; this plan intentionally makes no claim about whether an account identifier comes from a token claim, configuration, a provider response or another source. + +The canonical host-only envelope is: + +```text +CodexSanitizedMetadata { + account_id: absent | BoundedAsciiId(max 128 bytes), + provenance: unavailable | evidence_backed_host_source, +} +``` + +The v1 allowlist contains only `account_id`. When present, its bytes must be ASCII `[A-Za-z0-9._-]`, length 1–128, with no whitespace, colon, CR, LF or other header delimiter. `provenance` is a host-controlled enum, never a free-form RSS/model string. The host may emit `evidence_backed_host_source` only after the evidence record below is complete; a fixture-only value is marked `synthetic_fixture` in test evidence and cannot satisfy the live gate. + +- The host validates exactly one source value under the admitted provider policy. Missing metadata returns `unavailable`; if the trusted provider policy marks the header required, the host fails closed before network send with `codex_metadata_unavailable` and RSS cannot supply a fallback. +- Malformed, oversized, CR/LF-containing, conflicting or provenance-invalid values return typed `codex_metadata_invalid`/`codex_metadata_conflict` errors and perform no transport. No source wins by precedence when host inputs conflict. +- `account_id` is request-scoped for the initial Task 8 implementation. It is not written to `auth.yaml`, SQLite durable state, messages, events, metrics, artifacts or logs; the structural `auth.yaml` field remains unused until a separately evidenced policy decision authorizes persistence. +- RSS may pass only a bounded header-intent enum (for example, the admitted Codex default intent). It cannot pass an account-ID string, an alternate authority, a `ChatGPT-Account-ID` value, or arbitrary `originator`/`User-Agent` text. The host assembles the final `ChatGPT-Account-ID`, `originator` and `User-Agent` values from the trusted policy plus the validated envelope at the final transport boundary. + +Before Task 8 acceptance, the parent must attach a decision record with these required evidence fields: verified provider reference and version/date, exact metadata field and source kind, immutable fixture/artifact hash, bounded parser/validation rule, missing/conflict/invalid behavior, persistence decision, final header mapping and reviewer/verdict. The record must contain real verified values or explicitly record `unavailable`; this plan supplies no provider claim provenance. Until the record is frozen, the metadata gate status is `unavailable` and Task 8 cannot pass. + +Required pre-Task 8 tests use the real RSS entry and a fake host/provider: + +- valid bounded metadata produces the exact host-assembled header once, while RSS sees only the sanitized value and enum; +- missing required metadata fails closed; optional absence omits the header without accepting an RSS fallback; +- malformed, oversized, whitespace/CRLF/delimiter-containing and conflicting metadata produce typed errors before transport; +- RSS/model/user attempts to override the account ID, authority, header name, `originator` or `User-Agent` are rejected; +- policy-selected `originator`/`User-Agent` values are applied exactly and arbitrary header values never cross the host boundary; +- metadata, provenance evidence, synthetic secrets and any raw token-shaped source are absent from RSS maps, snapshots, auth files, durable state, events, logs and errors; +- synthetic fixture provenance is marked separately and cannot satisfy the evidence-backed live gate. + +Required request behavior: + +- Base URL defaults to `https://chatgpt.com/backend-api/codex` only in the RSS/provider policy or explicit public config; Rust does not inject a Codex default. +- Transport uses the Responses protocol expected by the Codex backend. +- Account metadata, when required, follows the host-only envelope and fail-closed rules above. +- Set Codex-compatible `originator` and `User-Agent` from trusted policy-approved values; never from user/RSS payload fields that bypass the policy. +- Authorization header is built at the final host transport boundary. +- RSS decides whether a 401 causes one refresh-and-retry for the same logical provider step; no duplicate `model.requested` row or turn count. +- RSS maps 429/quota distinctly from expired authentication. +- Streaming and cancellation preserve the existing durable provider contract. + +Tests use a local TLS/HTTP fixture or injected transport through the bridge; no live OpenAI call belongs in CI. Acceptance requires a complete real RSS agent turn using the fake Codex transport after `C-MIGRATION`, `C-PROVIDER-LOOP` and the Task 8-only metadata decision gate pass. + +--- + +## 7. Bundled coding agent default + +Change gateway startup so a production binary can run without a source checkout. RSS owns source selection/default policy and source-related business errors. Rust owns resource packaging, size/hash verification and the generic compile/startup gate. + +- Embed `rss/agent/main.rss` and its imports at build time or package them as verified resources beside the binary. +- `agent.source: bundled:coding` is the RSS default policy; the Rust startup layer only supplies/validates the selected structural source descriptor. +- `agent.source: file:/absolute/path.rss` enables custom source after size/hash/compile validation. +- Keep `RUSTSCRIPT_AGENT_SCRIPT` as a deprecated migration override only. +- Compile the selected source at startup and expose its hash in redacted health metadata. +- Startup fails before binding when the source or provider/auth reference is invalid. + +Files likely to change: + +```text +rss/agent/source_policy.rss +rss/agent/main.rss +src/bin/rustscript-agent-gateway.rs +src/service.rs +Cargo.toml +``` + +**Bridge contract:** RSS returns a bounded source-selection decision and public source descriptor; Rust verifies embedded/file resource identity, size and compile boundary, then returns an opaque verified-source handle. RSS agent behavior executes from the verified handle. No Rust source-name switch may implement coding-agent policy. + +Tests prove the installed binary can start from a directory containing no repository source files and that the real RSS entry is loaded. Invalid custom source fails before listen. The test must not require an authenticated provider call. + +--- + +## 8. Explicit workspace selection + +Add config and API fields for workspace selection. RSS owns workspace name/path selection, session binding policy, Telegram/API command meaning and user-facing errors. Rust owns canonicalization and the confined directory capability. + +- `workspaces.allowed_roots` defines canonical permitted roots. +- `workspaces.default` is optional and must lie under an allowed root. +- `POST /api/runs` accepts a workspace path or configured workspace name. +- Telegram session commands can select/status a workspace; the selected canonical path is durably attached to the session. +- Admission resolves the path once, opens the directory capability and freezes it into `RunLimits`. +- Symlink replacement after admission cannot escape the opened root. +- A request cannot select process cwd implicitly when no default is configured. + +Files likely to change: + +```text +rss/agent/workspace.rss +rss/storage/admission.rss +src/config.rs +src/gateway/api_server.rs +src/gateway/telegram.rs +src/service.rs +``` + +**RSS owner:** `rss/agent/workspace.rss` maps configured/named selections to policy decisions and sanitized errors; `rss/storage/admission.rss` emits the durable admission command. Gateway/Telegram modules remain thin input/output adapters. + +**Necessary Rust primitives:** canonicalize/open directory capability, root confinement, no-follow/symlink replacement resistance, admission freeze, durable session record and cancellation. Generic root/security validation remains host-side. + +**Bridge contract:** RSS sends a bounded selection plus the injected `OpaquePolicyHandle` to `workspace::open(selection, policy_handle)`; Rust checks the frozen policy generation and canonical roots, then returns an opaque workspace capability and canonical non-secret metadata. RSS cannot supply a capability token, add a root or bypass allowed roots. + +Existing file/process confinement tests become parameterized across default, named, denied, symlink and reopen cases. Add a real RSS session/admission entry test; it must use a fake host capability and must not require later provider runtime. + +--- + +## 9. Approval execution chain + +Wire existing approval persistence into the serial tool dispatcher. RSS owns approval policy, risk-class meaning, request/decision transitions, sanitized summaries and user-facing outcomes. Rust owns durable records, execution tokens, approval ceilings and effect revalidation. + +1. `read_file` and `search_files` follow configured read policy. +2. `write_file` and `patch` default to `ask`. +3. `terminal` and `process` default to `ask`. +4. Before `tool.started` or native effect, persist `approval.requested` with canonical call hash and expiry. +5. Expose approve/reject through HTTP and Telegram. +6. Resume the same durable tool call after approval; revalidation must detect changed name/arguments/parent. +7. Rejection, expiry, stop and restart produce one typed terminal tool result with no native effect. +8. Approval records contain sanitized summaries, never complete file contents, command output or credentials. + +Files likely to change: + +```text +src/service.rs +src/capabilities/lifecycle.rs +rss/tools/dispatch.rss +rss/storage/approvals.rss +src/gateway/api_server.rs +src/gateway/telegram.rs +``` + +**Bridge contract:** RSS passes the canonical RSS descriptor, call hash, requested risk intent and sanitized summary together with the injected `OpaquePolicyHandle` to `lifecycle::tool_prepare(request)`. Rust checks the frozen policy generation, workspace, deadline, cancellation and host-admitted approval ceiling before issuing an execution token; the ceiling never comes from RSS, model output or the approval request. RSS retains public tool dispatch ownership and cannot raise or downgrade a risk class after approval. + +The durable replay rule remains: an already completed/failed/interrupted canonical result bypasses both approval and native effect. + +Acceptance requires a real RSS dispatch entry covering no-effect-before-approval, reject/expire/stop/restart/replay, stale/revoked policy handles, a risk-class raise/ceiling-overreach attempt and an RSS risk-class downgrade attempt. The fake host must prove generic lifecycle enforcement without requiring future provider functionality. + +--- + +## 10. Production compaction + +Wire `rss/agent/compact.rss` into `AgentService`. RSS owns threshold/trigger policy, pair preservation, summary construction, explicit actions and failure/continue policy. Rust/storage owns durable transaction, generation, recovery and cancellation primitives. + +- Trigger before a provider request when configured message/token bounds are crossed. +- Expose explicit HTTP and Telegram compaction actions. +- Preserve tool-call/tool-result pairs and the durable generation contract. +- A compaction failure leaves original history readable and fails or continues according to explicit RSS policy. +- Restart resumes or fails pending compaction exactly once. +- The next provider request uses the committed summary plus retained tail. + +Files likely to change: + +```text +rss/agent/compact.rss +rss/agent/main.rss +rss/storage/compactions.rss +src/service.rs +src/gateway/api_server.rs +src/gateway/telegram.rs +``` + +**Bridge contract:** RSS emits typed storage commands and explicit compaction decisions; Rust/storage validates generation, durable ordering, recovery and cancellation, then returns committed state. Rust does not select the threshold, summary policy or business error mapping. + +Tests run a long real RSS coding loop across compaction and reopen, asserting no lost parent chain and bounded provider context. Add a direct RSS compaction entry test for threshold, explicit request, crash/reopen and pair preservation. The existing `max_context_messages: 120` and `retained_tail: 32` behavior remains the compatibility baseline. + +--- + +## 11. Task sequence and TDD gates + +The RSS-tool migration is the first implementation phase. Tasks 1–13 remain blocked until Tasks 0A–0F pass their gates, then follow the staged correction order in section 0. Every Task 1–13 entry below names its RSS owner, necessary generic Rust primitives, bridge contract and real RSS entry acceptance. A foundation task must use a fixture host when later runtime functionality is unavailable. + +### Task 0A: Define RSS tool contracts and registry + +**Files:** create `rss/tools/types.rss`, `rss/tools/registry.rss`, `rss/tools/validate.rss`; add `tests/rss_tool_registry_tests.rs`. + +**RED:** fixture tests for exact descriptors, deterministic ordering/identity, duplicate names, schema bounds, enablement and an extra fixture-only RSS tool that requires no Rust enum change. + +**GREEN:** RSS exports canonical descriptors and registry identity; Rust only performs generic structural bounds on the exported snapshot. + +**Commit:** `feat(tools): define rss tool registry contracts` + +### Task 0B: Add generic lifecycle execution tokens + +**Files:** create `src/capabilities/types.rs`, `src/capabilities/lifecycle.rs`, `src/capabilities/host.rs`; modify `src/runtime/agent_host.rs`, `src/service.rs`; add `tests/capability_lifecycle_tests.rs`. + +**RED:** durable-before-token, owner mismatch, replay, approval ceiling, deadline, cancellation, single-close, open-token recovery and panic cleanup tests. + +**GREEN:** expose `agent_runtime::tool_prepare` and `agent_runtime::tool_commit`; public tool names remain opaque. + +**Commit:** `feat(runtime): issue scoped tool capability tokens` + +### Task 0C: Migrate read-only file tools to RSS + +**Files:** create `src/capabilities/filesystem.rs`, `rss/tools/read_file.rss`, `rss/tools/search_files.rss`; modify `src/runtime/agent_host.rs`; add RSS/capability equivalence fixtures. + +**RED:** exact old/new envelopes for pagination, line numbering, regex/glob behavior, ordering, invalid paths, symlink races, cancellation and output caps. + +**GREEN:** RSS owns arguments, search/read algorithms and formatting; Rust exposes confined metadata/list/read-range primitives only. + +**Commit:** `feat(tools): implement file reads in rss` + +### Task 0D: Migrate mutating file tools to RSS + +**Files:** create `rss/tools/write_file.rss`, `rss/tools/patch.rss`; extend `src/capabilities/filesystem.rs`; add atomic-write and patch fixture tests. + +**RED:** exact write/patch envelopes, replacement uniqueness, patch grammar, expected-hash conflict, atomic replacement, file mode, symlink replacement, cancellation and interrupted recovery. + +**GREEN:** RSS owns write/patch semantics and diff formatting; Rust exposes atomic compare-and-write and root confinement only. + +**Commit:** `feat(tools): implement file mutation in rss` + +### Task 0E: Migrate process tools to RSS + +**Files:** create `src/capabilities/process.rs`, `rss/tools/terminal.rss`, `rss/tools/process.rss`; add process capability and RSS mapping tests. + +**RED:** spawn/poll/log/stdin/kill, cwd, environment allowlist, process group, output cursor, deadline, cancellation, stop and reopen fixtures. + +**GREEN:** RSS owns public terminal/process validation, actions and formatting; Rust owns opaque process resources and bounded native process operations. + +**Commit:** `feat(tools): implement process tools in rss` + +### Task 0F: Switch agent dispatch and remove native tool domain + +**Files:** create `rss/tools/dispatch.rss`; modify `rss/agent/main.rss`, `src/runtime/agent_host.rs`, `src/service.rs`, `src/config.rs`, `src/lib.rs`; remove superseded `src/tools/*`; update all tool/agent/gateway E2E. + +**RED:** architecture tests that fail while `agent::tool_dispatch`, `NativeToolExecutor`, built-in Rust tool order, public Rust descriptors or name-keyed Rust dispatch remain. + +**GREEN:** `rss/agent/main.rss` calls `tools::dispatch`; surviving generic code lives under `src/capabilities`; existing durable message/event contracts remain compatible. + +**Commit:** `refactor(tools): complete rss tool ownership` + +### Task 1: Address the integrated config/auth boundary + +**Status:** acceptance reopened for the boundary address. Existing integration `1c0b8dfd8aaac82552adf66cf0dee114f0af4e8f` remains in history and is not reverted. This task must pass Stage A before Task 2 continuation. + +**Objective:** add bounded structural config/auth schemas and path resolution while proving that provider selection/default/business interpretation is RSS-owned and that the foundation can be exercised through a minimal RSS entry. + +**RSS owner:** create `rss/config/entry.rss`. The entry reads a structural snapshot, exposes provider/model/source/workspace/auth references to later RSS policy, and preserves opaque credential references. It does not duplicate generic Rust structural declarations or implement OAuth, provider calls or full selection behavior yet; those remain later RSS tasks. + +**Necessary Rust primitives:** create `src/config_file.rs`, `src/auth/config.rs`; modify `src/config.rs`, `src/lib.rs`; retain bounded YAML, typed structural fields, strict key separation, home/path resolution, generic HTTPS/loopback and trusted-authority enforcement. Remove Rust `openai-codex` authority mapping, Codex endpoint/default interpretation, `local-agent` special cases and business defaults. Keep generic reference integrity where it protects the structural boundary. + +**Bridge contract:** `config::load_snapshot(host_home)` returns a `ConfigSnapshotEnvelope` with bounded public structural data, credential IDs, the injected policy handle/generation and sanitized policy summary. The RSS entry may inspect sanitized fields and opaque references; it cannot receive token fields or choose an authority. A fixture host implements this contract without Task 2 store, OAuth transport or authenticated runtime. + +**Files:** + +```text +src/config_file.rs +src/auth/config.rs +src/config.rs +src/lib.rs +rss/config/entry.rss +tests/config_file_tests.rs +tests/config_rss_entry_tests.rs +``` + +**RED:** tests for missing files, strict key separation, home override, invalid auth reference, HTTPS policy and bounded YAML; provider-name authority/default absence; policy-handle injection, policy replacement/forgery, stale-generation and expiry rejection, workspace-root/approval/header-ceiling overreach, and explicit custom-provider admission; a real RSS config/auth entry reading fixture data; no raw-secret fields in the RSS snapshot. + +**GREEN:** minimal loaders and typed validation. Rust retains structural data declarations and generic security checks only. No OAuth network code, provider selection engine, refresh policy or future runtime requirement is added. + +**RSS entry acceptance:** invoke the real `rss/config/entry.rss` through the fixture host and assert the selected structural references, trusted policy handle, path-qualified errors and secret absence. This is a foundation-only gate and must pass without Task 2 storage, Task 3 PKCE, Codex login or a real provider. + +**Commit:** `feat(config): split runtime settings from auth state` + +### Task 2: Snapshot-review and build the secure auth store + +**Status:** unaccepted. The interrupted Task 2 snapshot must be reviewed before continuation; no acceptance may be inferred from the existing integration commit. + +**Objective:** provide host-side credential persistence and concurrency primitives while keeping token lifecycle meaning and refresh/reauth policy in RSS. + +**Pre-continuation snapshot review:** the Task 2 parent first creates an immutable `StageBSnapshotRecord`; no review reads a mutable worktree in place. Required evidence fields are: + +- `snapshot_id`: SHA-256 of the canonical manifest bytes, explicitly distinct from every Git commit SHA; +- `parent_commit`, `base_commit`, `worktree_head`, branch and absolute worktree path, all recorded as full commit IDs or exact path values; +- UTC capture time, snapshot producer/command version and a `frozen_at` marker; +- `tracked_files`: every tracked path with index/worktree status, mode, byte length and SHA-256; +- `untracked_files`: every untracked regular file under the worktree, including ignored/generated files, with path, mode, byte length and SHA-256; no path may be silently omitted; +- `diff_artifacts`: content-addressed binary tracked diff from `parent_commit`, the untracked-file content manifest/artifacts and their SHA-256 hashes; +- `review_scope`: exact file ownership, raw-secret-flow scan, Rust provider-semantics scan, RSS entry/test inventory and the commands/evidence used; +- `review_verdict`: `unavailable` until the record is frozen, then `pending`, `pass` or `fail` with reviewer, time and findings. + +The parent computes and publishes this record before review; this plan supplies no snapshot ID, file hash or live Task 2 content. The snapshot gate is **unavailable** until all fields and artifacts are frozen. Any file change after freezing invalidates the record and requires a new content-addressed snapshot before review resumes. After the immutable record exists, inspect its exact diff/file scope and compare it with section 0. Check for provider-specific fields/branches, raw-token bridge exposure, Rust refresh decisions and missing RSS entry coverage. Classify and correct the frozen snapshot before extending it. Do not require Task 3 OAuth or Task 7 provider runtime for this review. + +**RSS owner:** create `rss/auth/store_entry.rss` (or extend the minimal auth entry from Task 1) to interpret status labels, rotation/reauth policy, save decisions and redacted user-facing outcomes. RSS passes opaque secret slots and expected generations only. + +**Necessary Rust primitives:** create `src/auth/store.rs`, `src/auth/token.rs`; bounded auth YAML persistence, Unix `0700`/`0600`, Windows ACL best effort, no-follow/symlink checks, lock, atomic replacement, flush/fsync/rename/parent fsync, generation CAS, opaque secret-slot provenance and redacted `Debug`. + +**Bridge contract:** `auth::load_metadata(credential_id, policy_handle)`, `auth::save_if_generation(request)`, `auth::access_handle(credential_id, expected_generation, policy_handle)`, `auth::refresh_handle(credential_id, expected_generation, policy_handle)` and `auth::delete(credential_id, policy_handle)` return only sanitized metadata/opaque handles. Raw token bytes remain inside the host store.

Refresh-token rotation is a storage primitive; RSS later decides when to invoke it. Do not add provider endpoint logic, retry policy, OAuth network calls or provider status interpretation to Rust. + +**RSS entry acceptance:** invoke the real RSS store entry with a fake host, cover corrupt/recovery, concurrent generation adoption and multi-credential preservation, and scan events/snapshots/output for raw synthetic secrets. Assert that a copied handle aliases one host entry, that duplicate/cross-run/restart use fails closed, and that local validation errors do not consume a valid refresh handle before its documented retry.

Delivery contract + +The finished system must satisfy all of these statements: + +1. Every model-visible tool is defined and implemented in `rss/tools/*`. +2. RSS owns public tool schemas, validation, dispatch, algorithms and result formatting; Rust owns only generic confined capabilities and lifecycle enforcement. +3. RSS owns provider/auth/refresh/retry/selection/default/source/workspace/approval/compaction business behavior; Rust owns generic security/resource primitives and trusted enforcement. +4. Rust production code contains no `NativeToolExecutor`, built-in public tool list/schema, provider-name business switch or public-name dispatch branches. +5. `rss/agent/main.rss` calls RSS tool dispatch directly; `agent::tool_dispatch` is removed. +6. A new RSS-only tool can be registered and executed without editing Rust dispatch code. +7. A fresh user can create config, run Codex device login, select a workspace and start the bundled coding agent without editing RSS or injecting a test provider. +8. OAuth access tokens refresh automatically and atomically: RSS decides when/how and Rust performs opaque-handle transport, CAS/locks and persistence. +9. `config.yaml` contains no credentials; `auth.yaml` contains no behavior policy. +10. Codex device-login policy is implemented in RSS; generic OAuth transport, PKCE, callback, storage and secret handling are implemented as Rust primitives inside `rustscript-agent`. +11. No OAuth functionality is added to RustScript core. +12. Raw auth material is absent from durable agent state, events, metrics, logs, artifacts and error text; RSS sees only sanitized provider data and opaque handles. +13. Provider/domain mapping is driven by trusted policy; RSS cannot replace the authorized authority or final Authorization boundary. +14. Mutating tool effects respect workspace and approval policy. +15. Long sessions compact durably and reopen without losing tool parent relationships. +16. Every Task 1+ capability has a real RSS entry acceptance through the explicit bridge; foundation tasks do not depend on future provider/runtime functionality. +17. Full debug and release suites pass from the final integrated commit. + +--- + +## 14. Main risks and chosen trade-offs + +- **RSS business logic still needs native safeguards:** every effect requires a Rust-issued execution token, and every provider request requires a trusted policy/opaque credential handle. Production host catalogs exclude unrestricted file/process APIs and arbitrary provider authorities that could bypass workspace, approval, deadline or durable lifecycle checks. +- **Structural schemas span Rust and RSS:** Rust keeps bounded typed declarations and persistence records where they express generic structure; RSS owns interpretation and policy. The plan avoids duplicating generic data merely to satisfy file ownership. +- **Migration can change output contracts:** each tool and provider bridge migrates against exact old/new fixtures before old native dispatch or raw `api_key` paths are removed. Public tool names and durable message/event shapes remain compatible. +- **YAML contains plaintext tokens:** initial scope uses strict local-file protection, locks and atomic writes. OS keychain integration may be added later behind the same `AuthStore` trait without changing RSS or provider contracts. +- **Codex device endpoints are provider-specific:** endpoint paths, defaults, response interpretation, pending/retry policy and state machine stay in RSS/config policy; Rust exports generic bounded transport, callback, handle and token persistence primitives. +- **Refresh tokens may rotate on every use:** RSS decides refresh timing and classification; per-credential serialization plus generation revalidation is mandatory from the first release. +- **Codex backend needs trusted headers:** the Task 8-only metadata gate requires verified evidence before any account-ID source is selected; until then no provider claim is made. Host-only metadata/header assembly and RSS header intent remain bounded by the trusted policy, with untrusted overrides rejected. +- **Existing provider bridge carries raw `api_key`:** `C-MIGRATION` then `C-PROVIDER-LOOP` are hard gates before authenticating runtime. The old profile/request shape cannot coexist with the opaque contract, and a fake-host loop cannot authorize live credentials. +- **Multiple auth entries:** named credentials are supported now; automatic pool rotation remains outside this plan. +- **Environment migration:** behavior settings move to `config.yaml`; environment remains only for selecting the agent home during bootstrap and for temporary compatibility reads. +- **Staged acceptance status:** the integrated Task 1 commit is preserved but reopened for the boundary address. The interrupted Task 2 snapshot requires review before continuation. These statuses remain visible until their focused RSS entry and bridge gates pass. diff --git a/rss/agent/main.rss b/rss/agent/main.rss index 2a9644a..36bc1f9 100644 --- a/rss/agent/main.rss +++ b/rss/agent/main.rss @@ -1,77 +1,16 @@ -// A5 serial loop policy skeleton (pure decision policy; no provider -// transport, no storage, no tool runner). +// Serial provider/tool agent loop. // -// The exported `run(context)` is a state-machine step function: ONE typed -// context map in, ONE discriminated decision map out.
