The loop builds canonical LlmRequest maps and invokes the selected provider adapter through a bounded native RSS host bridge in rss_runner; tool calls dispatch serially via the Task5 DispatchContext without resetting its cumulative budget. Follow-up assistant tool_call parts use lossless arguments_json strings, and tool results stay user-role tool_result parts so OpenAI Chat and other adapters consume one contract. Provider/network errors consume the existing retry/backoff budget; completed tool effects are never retried. Parallel and task dispatch stay typed unsupported. Tests drive a scripted provider plus the native dispatch bridge covering text-only, serial tools, retry, budgets, cancel/deadline, and malformed responses, and convert a real loop follow-up through the OpenAI Chat request builder. --- rss/agent/main.rss | 523 +++++++---- rss/llm/types.rss | 36 + src/domain.rs | 23 +- src/lib.rs | 1 + src/runtime/agent_host.rs | 454 ++++++++++ src/runtime/mod.rs | 2 + src/runtime/rss_runner.rs | 183 +++- tests/agent_loop_tests.rs | 1129 ++++++++++++------------ tests/domain_contract_tests.rs | 1 + tests/fixtures/agent/loop_context.json | 21 +- tests/provider_tests.rs | 224 ++++- 11 files changed, 1805 insertions(+), 792 deletions(-) create mode 100644 src/runtime/agent_host.rs diff --git a/rss/agent/main.rss b/rss/agent/main.rss index 2a9644a..e215359 100644 --- a/rss/agent/main.rss +++ b/rss/agent/main.rss @@ -1,77 +1,15 @@ -// 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.

Restore Stopping runs by requesting cancel before the next provider call, reject huge persisted deadlines as typed errors, treat injected providers as one-shot, and interrupt retry backoff on stop. Runner prepare/drive faults disarm the epoch watcher; process teardown reports a cleanup outcome instead of waiting unbounded. --- src/config.rs | 9 +- src/gateway/mod.rs | 23 +- src/lib.rs | 4 +- src/runtime/mod.rs | 1 + src/runtime/rss_runner.rs | 124 +++++++++-- src/service.rs | 397 +++++++++++++++++++++++++++++------ src/tools/dispatch.rs | 14 +- src/tools/process.rs | 94 ++++++--- tests/metrics_tests.rs | 83 ++++---- tests/run_lifecycle_tests.rs | 388 +++++++++++++++++++++++++++++++++- tests/runner_tests.rs | 63 ++++++ 11 files changed, 1040 insertions(+), 160 deletions(-) diff --git a/src/config.rs b/src/config.rs index 7492a94..031fe97 100644 --- a/src/config.rs +++ b/src/config.rs @@ -5,7 +5,9 @@ //! values.

Root-level +guidance files are read in this priority, highest first: `AGENTS.md`, +`CLAUDE.md`, `.cursorrules`. Default `CodingPromptBudgets` are 16 KiB total +prompt, 8 KiB combined guidance, and 4 KiB per guidance file. Each admitted +file is length-prefixed as untrusted content so project bytes cannot forge +later contract sections. The frozen prompt is reused as the sole system +message on every subsequent provider request for that run. + +## Provider profiles + +`ProviderProfile` is a validated, secret-safe snapshot retained on +`AgentService`. Built-in names map protocol labels only (`local-agent` → +`local-agent`, `openai` / `openai-compatible` → `openai-chat-completions`). +Options are request-shaping controls (`profile`, `protocol`, +`reasoning_effort`, `base_url`, sampling numbers). Credential-bearing keys, +headers, and unsafe URLs are rejected rather than redacted.

Client-disconnect policy is independent +(`keep-running` by default). + +## Durable replay + +Native dispatch is durable-first. Assistant `tool_call` parents and user +`tool_result` messages carry `parent_message_id` and monotonic `ordinal` +values.

The initial Codex path does not persist it. +- `account_id` is derived from the validated access-token JWT claim `https://api.openai.com/auth.chatgpt_account_id`; it is metadata, never trusted as authorization by itself. +- Refresh-token rotation increments `generation`. Writers must compare the generation observed before the network call and re-read under the auth lock before commit. +- Terminal refresh errors set `status: reauth_required` without deleting the last token pair. Transient network/5xx/429 errors leave credential state active and return a retryable typed error. + +### 2.4 File security and concurrency + +- Create home directory with Unix mode `0700`; create `auth.yaml`, lock and replacement files with `0600`. +- Reject symlink auth files and unsafe parent traversal; use no-follow/openat-style checks where supported. +- Read file through a bounded byte cap before parsing YAML. +- Save using same-directory exclusive temporary file, flush, fsync, atomic rename and parent-directory fsync. +- Protect read-modify-write using an in-process mutex plus cross-process lock. +- Never serialize auth structs through `Debug`; implement redacted summaries. +- Windows tests verify atomic replacement and best available ACL/file handling without claiming POSIX mode guarantees. +- Corrupt YAML is moved or copied to a timestamped `.corrupt` artifact only after a bounded read; startup/login returns a typed error and never silently starts from an empty credential set. + +## 3. Rust OAuth boundary + +All new OAuth code lives in this repository. No OAuth type, host function or provider special case is added to `pd-vm` or any other RustScript core crate. + +### 3.1 Library modules + +Create: + +```text +src/auth/mod.rs +src/auth/config.rs +src/auth/store.rs +src/auth/oauth.rs +src/auth/host.rs +src/auth/pkce.rs +src/auth/token.rs +``` + +Core public types: + +```rust +pub struct AuthStore; +pub struct CredentialId(String); +pub struct OAuthProviderConfig; +pub struct OAuthTokenSet; +pub struct OAuthClient; +pub struct OAuthSession; +pub enum OAuthFlowKind { AuthorizationCodePkce, DeviceCode } +pub enum AuthStatus { Active, ReauthRequired, Disabled } +pub enum OAuthErrorCode; +``` + +`OAuthClient` receives an injected clock, HTTP transport, browser opener and loopback listener factory so tests never contact live providers. + +### 3.2 Generic native operations + +Expose library functions and matching RSS host functions under an `oauth::` namespace: + +```text +oauth::request(auth_id, operation, payload) -> typed response +oauth::save_tokens(auth_id, token_response) -> credential metadata +oauth::access_token(auth_id) -> short-lived access envelope +oauth::status(auth_id) -> redacted metadata +oauth::delete(auth_id) -> typed result +``` + +`operation` is a symbolic operation configured by Rust (`device_start`, `device_poll`, `token_exchange`, `refresh`). RSS cannot pass an arbitrary URL, HTTP method or Authorization header. Rust resolves endpoint, method, body encoding, timeout and allowed authority from `config.yaml`. + +`oauth::request` returns bounded provider data: + +```json +{ + "ok": true, + "status": 200, + "body": {}, + "retry_after_ms": null +} +``` + +The host enforces: + +- HTTPS remote endpoint and configured authority. +- bounded 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. + +`oauth::save_tokens` accepts a provider response only from the active in-memory OAuth session. It validates access token, optional refresh rotation, token type and expiry before calling `AuthStore`. + +`oauth::access_token` returns only access token, token type, expiry and derived account ID to the ephemeral provider invocation. It never returns refresh token to RSS. + +### 3.3 Generic authorization-code OAuth flow + +Rust implements a reusable Authorization Code + PKCE S256 flow: + +1. Generate cryptographically random verifier and state. +2. Build authorization URL from the selected provider config. +3. Bind a random loopback port on `127.0.0.1` and accept one bounded callback. +4. Open the browser when available. +5. Validate exact state and single-use callback session. +6. Exchange code using form encoding and the configured token endpoint. +7. Persist validated tokens through `AuthStore`. +8. On SSH/headless systems, print the URL and accept a pasted callback URL/code through the CLI without weakening state/PKCE checks. +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. + +### 3.4 Generic refresh flow + +Rust owns token refresh for every OAuth provider: + +1. Read credential and generation. +2. If access token remains valid beyond `refresh_skew_seconds`, return it. +3. Serialize refresh per credential ID; re-read after acquiring the lock. +4. POST `grant_type=refresh_token` with client ID and current refresh token. +5. Require a new access token. +6. Preserve old refresh token if the response omits one; atomically replace it when rotated. +7. Update absolute expiry from `expires_in`, with bounded clock-skew handling. +8. Classify `invalid_grant`, `invalid_token`, HTTP 401/403 and consumed refresh token as `reauth_required`. +9. Classify 429 using `Retry-After`; keep existing credential active and expose a retryable/quota error. +10. Treat transport timeout and 5xx as retryable; never overwrite a valid credential with a partial response. + +Two gateway processes racing a single-use refresh token converge through the auth file lock and generation check. The later process adopts the newer generation rather than replaying the old refresh token. + +## 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 Rust host functions. + +### 4.1 State sequence + +1. Call `oauth::request(auth_id, "device_start", {client_id})`. +2. Parse `user_code`, `device_auth_id` and `interval`; reject missing/wrong-type/oversized fields. +3. Emit a sanitized CLI instruction containing `https://auth.openai.com/codex/device` and the user code. The device auth ID remains internal. +4. Poll `device_poll` with `{device_auth_id, 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`; no tight polling. +7. Parse `authorization_code` and `code_verifier` from the successful poll response. +8. Call `token_exchange` using authorization-code grant, configured redirect URI and verifier. +9. Call `oauth::save_tokens`; report only redacted credential metadata. +10. Clear all transient values before return on success, rejection, cancellation or timeout. + +### 4.2 Required RSS tests + +Use a fake native OAuth host and fixture responses to cover: + +- happy path and exact operation order. +- pending 403/404 followed by success. +- 429 backoff and absolute deadline. +- cancellation during wait. +- malformed start, poll and exchange responses. +- exchange with missing access token. +- refresh token present/absent in initial exchange. +- no raw token/device auth ID 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. + +Commands: + +```text +rustscript-agent auth login openai-codex +rustscript-agent auth login +rustscript-agent auth status [provider] +rustscript-agent auth logout +rustscript-agent config path +rustscript-agent config check +rustscript-agent run --script ... +``` + +Legacy `rustscript-agent --script ...` remains an alias for `run` during migration. + +Files likely to change: + +```text +src/bin/rustscript-agent.rs +src/bin/rustscript-agent-gateway.rs +src/config.rs +src/lib.rs +``` + +CLI acceptance criteria: + +- Login writes only `auth.yaml`; provider/model 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. + +## 6. Runtime provider integration + +### 6.1 Credential resolution + +At run admission, freeze only the credential ID and provider configuration hash. Immediately before each real provider request: + +1. Resolve the named credential through `AuthManager`. +2. Refresh when required. +3. Construct an ephemeral provider transport profile. +4. Invoke the RSS provider adapter. +5. Drop the token-bearing profile after the call. + +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 +src/runtime/rss_runner.rs +``` + +Required request behavior: + +- Base URL defaults to `https://chatgpt.com/backend-api/codex` from config. +- Transport uses the Responses protocol expected by the Codex backend. +- Rust derives `ChatGPT-Account-ID` from the access-token JWT claim and exposes it only to the ephemeral adapter profile. +- Set the Codex-compatible `originator` and `User-Agent` headers from trusted native configuration, never from user/RSS payload. +- Authorization header is built at the final transport boundary. +- 401 triggers one refresh-and-retry for the same logical provider step; no duplicate `model.requested` row or turn count. +- 429/quota remains distinct from expired authentication. +- Streaming and cancellation preserve the existing durable provider contract. + +Tests use a local TLS/HTTP fixture or injected transport; no live OpenAI call belongs in CI. + +## 7. Bundled coding agent default + +Change gateway startup so a production binary can run without a source checkout: + +- 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 default. +- `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. + +Tests prove the installed binary can start from a directory containing no repository source files. + +## 8. Explicit workspace selection + +Add config and API fields for workspace selection: + +- `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. + +Existing file/process confinement tests become parameterized across default, named, denied, symlink and reopen cases. + +## 9. Approval execution chain + +Wire existing approval persistence into the serial tool dispatcher: + +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. + +The durable replay rule remains: an already completed/failed/interrupted canonical result bypasses both approval and native effect. + +## 10. Production compaction + +Wire `rss/agent/compact.rss` into `AgentService`: + +- 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 policy. +- Restart resumes or fails pending compaction exactly once. +- The next provider request uses the committed summary plus retained tail. + +Tests run a long real coding loop across compaction and reopen, asserting no lost parent chain and bounded provider context. + +## 11.

Delivery contract + +The finished system must satisfy all of these statements: + +1. 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. +2. OAuth access tokens refresh automatically and atomically; refresh-token rotation survives concurrent gateway/CLI access. +3. `config.yaml` contains no credentials; `auth.yaml` contains no behavior policy. +4. Codex device-login policy is implemented in RSS; generic OAuth transport, PKCE, storage and refresh are implemented in Rust inside `rustscript-agent`. +5. No OAuth functionality is added to RustScript core. +6. Raw auth material is absent from durable agent state, events, metrics, logs, artifacts and error text. +7. Mutating tool effects respect workspace and approval policy. +8. Long sessions compact durably and reopen without losing tool parent relationships. +9. Full debug and release suites pass from the final integrated commit. + +## 14. Main risks and chosen trade-offs + +- **YAML contains plaintext tokens:** initial scope uses strict local-file protection 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 and response interpretation stay in RSS/config; Rust exports symbolic confined operations and generic token persistence. +- **Refresh tokens may rotate on every use:** per-credential serialization plus generation revalidation is mandatory from the first release. +- **Codex backend needs trusted headers:** account ID is derived natively from JWT; originator/User-Agent are trusted config constants and cannot come from a run request. +- **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.

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 prevents tool behavior from being authored, replaced and distributed as RSS modules. + +## 3. Target module layout + +### 3.1 RSS-owned tools + +```text +rss/tools/ +├── types.rss +├── registry.rss +├── validate.rss +├── dispatch.rss +├── read_file.rss +├── search_files.rss +├── write_file.rss +├── patch.rss +├── terminal.rss +└── process.rss +``` + +Each public tool module exports: + +```text +pub fn descriptor() -> map +pub fn validate(arguments: map) -> map +pub fn execute(context: map, arguments: map) -> map +``` + +`descriptor()` returns the canonical provider-facing structure: + +```json +{ + "name": "read_file", + "description": "...", + "input_schema": {}, + "risk_class": "read", + "toolset": "coding" +} +``` + +`validate()` returns a typed RSS result and cannot perform native effects. + +`execute()` calls generic capabilities using the execution token supplied by the lifecycle layer and returns the canonical RSS `ToolResult` map. + +`registry.rss` explicitly orders enabled descriptors. It canonicalizes the descriptor array before hashing and exports: + +```text +pub fn descriptors(config: map) -> array +pub fn identity(config: map) -> map +pub fn find(name: string, config: map) -> map +``` + +`dispatch.rss` performs lookup, validation, lifecycle preparation, execution and final commit. + +### 3.2 Generic Rust capabilities + +Replace tool-domain Rust modules with: + +```text +src/capabilities/ +├── mod.rs +├── filesystem.rs +├── process.rs +├── lifecycle.rs +├── artifacts.rs +├── host.rs +└── types.rs +``` + +The capability layer may know operation names such as `fs_read_range`, `fs_write_atomic`, `process_spawn` and `process_poll`. These names describe native primitives and are never presented to a model. + +Capability APIs are registered under namespaces separate from the agent tools: + +```text +cap::fs_metadata(execution_token, path) +cap::fs_read_range(execution_token, path, offset, limit) +cap::fs_list(execution_token, path, cursor, limit) +cap::fs_write_atomic(execution_token, path, expected_hash, bytes) +cap::process_spawn(execution_token, argv, cwd, env_names, limits) +cap::process_poll(execution_token, process_handle, cursor, limit) +cap::process_write(execution_token, process_handle, bytes) +cap::process_kill(execution_token, process_handle) +cap::artifact_put(execution_token, bytes, metadata) +``` + +The exact host schema uses typed maps/resources supported by pd-vm. Public model tool descriptors never reuse these capability schemas. + +## 4. Execution lifecycle + +### 4.1 Preparation + +RSS receives one provider tool call and validates it against the RSS descriptor.

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.

Main risks and chosen trade-offs +- **RSS tool logic still needs native safeguards:** every effect requires a Rust-issued execution token. Production host catalogs exclude unrestricted file/process APIs that could bypass workspace, approval, deadline or durable lifecycle checks. +- **Migration can change output contracts:** each tool migrates against exact old/new fixtures before old native dispatch is removed. Public tool names and durable message/event shapes remain compatible. - **YAML contains plaintext tokens:** initial scope uses strict local-file protection 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 and response interpretation stay in RSS/config; Rust exports symbolic confined operations and generic token persistence. - **Refresh tokens may rotate on every use:** per-credential serialization plus generation revalidation is mandatory from the first release.

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.

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.

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.
