## Why
Resuming or forking a thread loses the session flag indicating that reported token usage already includes retained reasoning. Counting that reasoning again can trigger automatic compaction too early.
## What changed
Persist `last_usage_includes_reasoning` with `TokenUsageInfo` and use it when estimating context usage. Record the flag with completed sampling and compaction usage, and mark local estimates as including reasoning. Older records without the field retain the existing accounting behavior.
## Testing
Add coverage for saved inclusive, exclusive, and legacy token counts. Extend the encrypted-reasoning compaction test to verify the compaction threshold for live, forked, and cold-resumed threads.
GitOrigin-RevId: 9f22262a693111ec0406dce11804eb4844ad8983
## What changed
Add an output schema for `image_gen.imagegen` so its code-mode declaration returns `Promise<{ image_url: string; output_hint?: string; }>`. Direct API tool serialization remains unchanged.
## Testing
Add coverage for the generated return type and unchanged direct API serialization, assert the full declaration in the app-server integration test, and verify that code-mode results omit oversized output hints.
GitOrigin-RevId: b3cee52a6b68c881f0c7507e791cc0fe86ca0d24
## What changed
Add `ReviewInput` to bundle an approval request with its captured parent history and review context. Its `assess_isolated` method runs a fresh reviewer without publishing a live approval, honors deadlines and cancellation, and returns a `GuardianAssessment` or review error.
Share review parameter construction with the live review path and extract assessment parsing and error conversion into `GuardianReviewSessionOutcome::into_assessment`.
## Testing
Add a mock-backed test that verifies the isolated assessment is returned and the reviewer receives the captured history without instructions added after capture.
GitOrigin-RevId: 10dd5fddf5fc58bfab124f5962a6b7f45d435c83
## What changed
- Separate evidence collection from prompt preparation and pass reviewer history, model limits, and image preparation policy through shared `guardian-context` APIs.
- Detect captured images before composition and measure reviewer history tokens only when images and a valid context window require it.
- Share instruction and native-message delivery filtering across budget checks, including restoration of retained evidence after history changes.
GitOrigin-RevId: 65ef53cf0bc22e1bde9abfb7a9ffce65cfab6f1c
## Why
Guardian's `write_stdin` approval requests lacked the command used to launch the receiving terminal, leaving reviews without that context.
## What changed
- Carry `original_command` from the terminal's launch command into the approval request and Guardian action JSON. This describes the original launch, not the terminal's current state.
- Exclude `original_command` from the 8,000-byte stdin approval size check so launch context does not consume the budget for input, permission details, and the approval reason. Launch context remains subject to Guardian's normal request budget.
## Testing
Extend serialization coverage to check `original_command` and the strict stdin review integration test to verify that a launch command longer than 8,000 bytes reaches Guardian intact.
GitOrigin-RevId: cc765a6bf80d080baf94c959eafa6227b2889e1f
## What changed
Decode `response.metadata` Guardian assessments into typed `GuardianAssessment` events over SSE and WebSocket, carrying `response_id`, `item_id`, and `requires_review`. Ignore assessments with missing, empty, or incorrectly typed required fields while preserving independent delivery of other metadata.
Expose the assessment type to request-scoped extension interceptors. Keep assessments out of conversation history; they do not authorize tool execution.
## Testing
Add SSE coverage for assessment ordering, malformed metadata, and mixed metadata delivery. Extend model request tests to cover SSE and WebSocket interceptor delivery and exclusion from subsequent model input.
GitOrigin-RevId: 282b8817ee97346d76b40bcb412eef023df60ff1
## What changed
Extract MCP approval elicitation parsing and review-decision response conversion from `core/src/session/mcp.rs` into `codex-guardian-reviewer`. Export the helpers and `GuardianElicitationReview` for the session code to use, while keeping session lookup, provenance checks, and approval enforcement in the host.
## Testing
Move the existing elicitation tests into the reviewer crate, retaining coverage for request construction, opt-in requirements, unsupported forms, decision mapping, and model-specific timeout instructions.
GitOrigin-RevId: fb745fa0e49a29f015bbda16c14b5fc2b12278b9
## What changed
Export `ReviewAction` and its conversion from `GuardianApprovalRequest` from
`codex-guardian-reviewer`. Keep host-specific approval preparation and environment
validation in core as standalone functions, and update callers accordingly.
## Testing
Move the `write_stdin` serialization and tool-call provenance test into the
reviewer crate, preserving coverage for input, Windows working directories, and
sandbox permission modes.
GitOrigin-RevId: 9a1caf9bbb67ba017e4950a2da9ef2543b013007
## What changed
Move review evidence storage, authorization snapshots, sender exchange selection,
and bounded Node REPL evidence into `codex-guardian-reviewer`. Update core to
call or re-export these APIs while retaining host-specific context rendering and
capture-mode selection.
Move the existing Node REPL evidence and text truncation tests alongside their
implementations in the reviewer crate.
GitOrigin-RevId: d851cd353cf9f31eb47ce13f43f6f935dc2f5d93
## What changed
Move `GuardianContextMode`, parent compaction checkpoint policy, and reviewer instruction assembly into `codex-guardian-reviewer`. Export the conversation-history prompt and follow-up reminder from the same crate, and update core to use these shared definitions.
Keep session-specific authorization version lookup in core while preserving existing context selection, checkpoint validation, and prompt behavior.
GitOrigin-RevId: a4cadb6c8ad95e756467316b7d8658e8cd527b24
## What changed
Move review state, fork history, checkpoint recovery bookkeeping, and Node REPL evidence admission into `codex-guardian-reviewer`. Expose helpers for session initialization and snapshot publication, and update core to delegate to them while preserving the existing review logic.
GitOrigin-RevId: 56d6a0124301a3c70908614d4bc3bfe970ac1c85
## Why
Repeated repository skill discovery performs remote metadata requests even when no `.agents/skills` directories exist. Reuse verified empty results to avoid those round trips while watching for changes that require a new scan.
## What changed
- Add the Linux executor capability `fs_watch_missing`, the `fs/watchMissing` request, and `fs/missingChanged` notifications.
- Register watches in the background and reuse empty results only after the executor acknowledges coverage. Key reuse by filesystem, working directory, and project root markers.
- Invalidate observations on relevant filesystem or mount changes, watch supersession, or connection loss. Clear cached observations on forced reloads and cache resets.
- Retain live discovery while registration is pending or watching is unsupported, unavailable, or cannot verify the observation.
## Testing
Add tests for empty-result reuse and invalidation, skill directory creation before watch acknowledgement, unsupported executors, idle WebSocket notifications, reconnection, case aliases, and bind mounts and unmounts. Include an ignored manual latency comparison for repeated empty remote scans.
GitOrigin-RevId: 3ad499decefb184a99c068afa01d0dcdd8605c7f
## What changed
- Add `CodexThread::create_child` to create an idle child from a live tool invocation using a host-reserved thread ID and controller.
- Add `prepare_child` and `ThreadManager::create_prepared_child` to capture inherited settings and fresh or forked history, then start the child on another manager even after the parent shuts down. Reject detached preparation when live bindings cannot be transferred.
- Add opt-in `HostToolInvocationLookup` to track live calls and reject duplicate active call IDs within a turn. Revoke invocation access when dispatch ends and clean up provisional children when startup fails or is cancelled.
## Testing
Add tests for invocation lifetime and call ID reservation, inherited policy and live bindings, detached startup with fresh and full history, and cancellation cleanup.
GitOrigin-RevId: 71f17ecb4cd7636517e675df59289a8e8c7105b8
## What changed
Expose the backend-provided `generationId` on image-generation items and preserve it through legacy completion events, thread history reconstruction, and rollout migration. Default missing IDs to `None` for older history.
Update the generated JSON schemas, TypeScript types, and Python models to include the nullable field.
## Testing
Extend coverage for ID serialization round trips, completed-item notifications, persisted and resumed history, and legacy rollout migration.
GitOrigin-RevId: a7f06faa7ac6833417b257a535d2901c03b79135
## What changed
Expose `literature_search_query` in standalone `web.run` when the active model lists it in `experimental_supported_tools`. Support query text, domain filters, and recency filters, and reject literature search calls for models without the capability.
Pass the active model information to extensions for each step and report literature queries as search actions in web search events.
## Testing
Add coverage for capability rejection, model-dependent schema exposure, app-server round trips with a turn-level model override, and a scenario that searches for a paper and opens the returned reference.
GitOrigin-RevId: 87ef1fadd80ca7bfc2a7642c4e443f9b9f2e0e00
## What changed
Add `ReviewerPool::review_isolated` to run a review in a temporary session without reading or changing the reusable reviewer. Build the request context without a previous session and spawn without a cached snapshot.
## Testing
Add a test verifying that an isolated review receives no snapshot, uses a separate session, and preserves the prewarmed session for the next regular review.
GitOrigin-RevId: 6cceff0c399f30f3c3303b0bf5232c274c902e3a
## What changed
Keep original scheduled messages and heartbeat provenance during synchronous transcript collection. Add `prepare_sync_context` to compress repeated heartbeat instructions across the complete collected transcript before selecting the requested suffix, preserving reference numbering in full and delta prompts.
Route synchronous reviewer prompts through this preparation step and reject composition of unprepared scheduled messages. Move transcript profiles and REPL evidence rendering into the preparation module. Asynchronous heartbeat compression remains in collection.
## Testing
Extend heartbeat transcript coverage to compare prepared full and delta prompts with the existing rendering and verify that direct composition rejects unprepared scheduled messages.
GitOrigin-RevId: c9824b8862021301a1f537a74f83bc7eb20aa0ad
## What changed
Move planned-action construction from the core Guardian prompt builder into the exported `codex_guardian_reviewer::build_guardian_planned_action` helper. Keep the existing action kinds, MCP tool and connector descriptions, and reason selection unchanged.
GitOrigin-RevId: 119323523ed2e199c998c1139fb8e6255bc730d9
## What changed
Move approval-request assessment and analytics mappings, target item lookup, and turn ID selection into `codex-guardian-reviewer`. Export the helpers from the crate and re-export them in core, preserving existing behavior.
## Testing
Move the apply-patch serialization test into the reviewer crate. It checks that Windows paths are preserved and patch text is omitted from the assessment action.
GitOrigin-RevId: 3a011db0bc51c653bb0877c4b0cb52eb61c63244
## What changed
Add the disabled-by-default `omit_skill_descriptions` feature flag to omit descriptions from model-visible host, executor, and cloud skill catalogs while retaining names and locators. Adapt catalog introductions, usage instructions, and alias budget accounting to the selected policy.
Persist the description policy in catalog snapshots and refresh usage instructions when it changes. Ignore description-only edits in catalog deltas while descriptions are omitted.
## Testing
Add coverage for alias token budgets, policy changes with older snapshots, and suppressed description-only updates. Extend scenario snapshots to cover plugin visibility and catalog deduplication with descriptions omitted.
GitOrigin-RevId: 5bf1dcee8c04059c7a78998affc1efcdef8ec883
## What changed
- Retain captured root conversation sources until synchronous preparation applies request limits. Keep asynchronous snapshots limited to the bounded messages.
- Move approval-reason truncation and tool-description escaping and truncation from composition into preparation.
- Extract synchronous image preparation and admission into `guardian-context`, preserving the prompt token cap and model context-window checks.
GitOrigin-RevId: d3a864c77d8f16bd3e77df436d80c4d2738c43cc
## What changed
Move approval request serialization and model-visible action formatting from `codex-core` into `codex-guardian-reviewer`, expose both helpers publicly, and re-export them from core. Preserve the existing JSON shapes and formatting.
## Testing
Move the MCP tool-call and network-access trigger serialization tests into the reviewer crate, retaining coverage for omitted optional fields and Windows path rendering.
GitOrigin-RevId: c0093c023b2f4c1be16bac481f1173a5da6ac25c
## What changed
Export `GuardianPromptItems` and `compose_guardian_prompt` from `codex-guardian-reviewer`, and delegate prompt composition from core to the new helper. Core continues to collect context sections and choose the history version.
Preserve full and delta transcript selection, empty-transcript placeholders, cursor accounting, and Node REPL evidence sequencing.
GitOrigin-RevId: e3e2b2a87a42709ddb5441f47cbb7461b0130579
## What changed
Export `GuardianApprovalRequest`, `GuardianNetworkAccessTrigger`, and
`GuardianMcpAnnotations` from `codex-guardian-reviewer` and re-export them in
core. Move environment lookup and scope classification with the request type,
preserving existing classification and credential-safe debug output.
GitOrigin-RevId: 5253a5124d5e370a1230b46aa7dc48b24b1c902e
## What changed
Move Guardian session-source detection, the reviewer name constant, and parent-thread prompt cache key generation into `codex-guardian-reviewer`. Re-export them from core, preserving existing behavior.
## Testing
Move the existing prompt cache key test into the reviewer crate, retaining coverage for parent-thread scoping, key length, and missing or inapplicable inputs.
GitOrigin-RevId: c14b3c030ba93676a0799aba56b23a676dbbc56d
## What changed
Export `token_usage_delta` from `codex-guardian-reviewer` and use it in the core review session. Preserve the existing calculation, including clamping negative deltas to zero.
## Testing
Move the existing nonnegative token usage delta test alongside the helper in the reviewer crate.
GitOrigin-RevId: fcfce24b8d50a63dcd1122a4204939bc6750feda
## What changed
Add `GuardianScope::for_multi_agent_tool` and use it for both tool review requirements and asynchronous scoring. Classify `spawn_agent`, `send_message`, `followup_task`, and `interrupt_agent` as native tools when they match the configured namespace, accepting default namespace spellings when none is configured. Keep review enablement checks at each call site.
GitOrigin-RevId: 9180ccdc629532f6c171d899dc5881e15b447141
## What changed
- Recognize `policy_capacity_unavailable` in HTTP and streaming API errors and expose it as `policyCapacityUnavailable` through the app-server protocol and generated bindings.
- Display “Policy-restricted capacity is unavailable. Please try again later.” while preserving overload retry behavior based on `Retry-After`.
- Handle the new error in TUI overload rendering, reviewer retries, and error telemetry.
## Testing
Add coverage for HTTP and streaming error classification, retry advice, WebSocket terminal error attribution, protocol serialization, and TUI rendering with and without an upstream message.
GitOrigin-RevId: 1b9536fba1e11cc891dcf689aee35410d82f5412
## What changed
When `GuardianNativeMultiAgentHistory` is enabled, require Guardian review for wrapped Multi-Agent V2 calls to `spawn_agent`, `send_message`, `followup_task`, and `interrupt_agent`.
Include these calls in Guardian's asynchronous native-tool scoring scope, honoring the configured multi-agent namespace and preserving that configuration across overrides.
## Testing
Extend the incremental-review scenario with an encrypted, namespaced `send_message` call. Verify that the encrypted parent reply remains present exactly once in both Guardian reviews and the subsequent agent request, and update the snapshot to cover native tool-call review evidence.
GitOrigin-RevId: 2af9561b0d69af4a8f878fa32365ce845368e02d
## Why
Native multi-agent calls must stay intact for backend decryption during Guardian review.
## What changed
When `guardian_native_multi_agent_history` is enabled for multi-agent v2, preserve `spawn_agent`, `send_message`, `followup_task`, and `interrupt_agent` function calls in the configured tool namespace as native transcript items. Use `functions` when no namespace is configured.
Include the paired evidence-only output in token accounting, and omit native evidence whole when limits require it.
## Testing
Extend transcript tests to cover native call ordering, paired-output budgeting, and whole-item omission. Add a native-history snapshot alongside the existing text-history delegation handoff scenario.
GitOrigin-RevId: e7d9b4f5ea772890bf14b79fdb53b0f9d0a842e4
## Why
Custom OpenAI base URLs caused Codex backend authentication to lose Responses headers and Guardian metadata when the URL did not match a recognized backend route.
## What changed
Apply model-scoped Responses headers, Guardian reviewer and classifier markers, and eligible ChatGPT parent credit requests based on the OpenAI provider and authentication configuration, regardless of the base URL. Keep API-key requests and other providers excluded from this behavior.
## Testing
Extend coverage for custom `/v1` URLs and direct `/api/codex` endpoints with ChatGPT, header-based, and API-key authentication, including HTTP fallback and WebSocket requests.
GitOrigin-RevId: cc4bb5b4a1a6596904ecf8965237c7a4f09e112b
## What changed
- Add `CoreToolRuntime::requires_guardian_review` to review opted-in function calls before dispatch and stop execution when review rejects the call.
- Deliver proposed calls as native review evidence, preserving encrypted argument metadata. When hooks rewrite arguments, review the updated arguments and discard the original encrypted replay content.
- Deduplicate native call evidence against reviewer history and include paired evidence outputs in input budgets.
- Keep review accounting and metrics for native calls without emitting action-specific client assessment events, and omit approval payloads from debug output.
## Testing
Extend regression coverage for rewritten native calls across review retries, denied calls that never execute their handlers, oversized native evidence, and review metrics without client events.
GitOrigin-RevId: c3b22c0220344581c2b38f233001abaed49cba34
## What changed
- Replace Rust `1.99.1` pins with `1.95.0` across Cargo, Bazel, CI, release workflows, and Windows setup, and update the Bazel lockfile.
- Adjust Rust APIs, borrowing, and lint-related code for the pinned toolchain, and box MCP tool dispatch to bound compiler async-layout query depth.
- Update the halfwidth sound mark snapshot and allow optional symbol hash suffixes in the code mode host package smoke test.
GitOrigin-RevId: 75460c3d0465dc601811e619bce373a4f7ff2912
## What changed
Collect original retained instructions, assistant context, and verified answers before applying synchronous request limits in `guardian-context` preparation. Carry original record sizes through collection, preserving whole-record omission notices, source ordering, and host assistant-context framing.
Apply retained transcript source size checks during synchronous transcript preparation as well.
## Testing
Extend regression assertions for synchronous/asynchronous retained-context parity and equivalent verified-answer omissions when oversized records are filtered during preparation.
GitOrigin-RevId: 9042ee3fe60ebd455f6656b4008efb2acc44ac3d
## What changed
Add `WorldStateSectionContribution::with_window_prefix()` to render extension developer fragments as separate messages before retained history when building a context window, including after compaction. Updates within an existing window still append to history. Ignore fragments with other roles for sections that opt in.
## Testing
Add a unit test for prefix placement and duplicate avoidance, plus local and remote compaction scenarios covering live updates, persisted replacement history, and rejection of non-developer fragments.
GitOrigin-RevId: 8621457c6eec17f1585ca8e6fa154b1bf3257330
## Why
Image generation usage-limit errors with the `imagegen_premium` limit ID were not recognized as structured `UsageLimitExceeded` failures.
## What changed
Recognize `imagegen_premium` alongside `image_gen`, preserving the limit ID and available reset time in image generation failure metadata.
## Testing
Extend app-server coverage to verify premium limit metadata and reset-time fallback in completion events, thread reads, and resumed threads. Add unit coverage for missing exhausted-window reset times and unrelated or absent limit IDs.
GitOrigin-RevId: 8cf991776403ddce1f45d9780b8040982fd0fcfe
## What changed
- Add the disabled-by-default `skill_catalog_deltas` feature flag to append new and updated skills without repeating unchanged catalog entries.
- Share a cumulative metadata budget across executor, cloud, and host catalogs, preserving usage across turns and resume. Removals emit no update and do not refund budget.
- Rebuild the current catalog and reset its budget after compaction, including any required skill root mappings in updates.
## Testing
Add unit and integration coverage for update costs, shared source budgets, feature rollback, and catalog updates across resume and compaction, with a request-history snapshot.
GitOrigin-RevId: e88b4265d7361498113d43fdc2e0260a9f930bbc
## Why
Each turn runs an external hook, making a shared ten-second deadline too restrictive. Turn completion can also precede deletion of the queued item.
## What changed
Use the event waits' progress deadlines in the rejected-message test and wait for the queue to empty before checking results, replacing the immediate empty-queue assertion.
GitOrigin-RevId: 2b417840156893d829dc2984aa88b06a5a13aefe
## Why
Existing databases retain their journal mode, so selecting `DELETE` for new NFS databases leaves existing WAL databases unchanged.
## What changed
- Add the managed `unsafe_enforce_sqlite_journal_mode` requirement to migrate existing NFS databases before opening writable pools and require `DELETE` on each connection.
- Share migration code between startup and `codex migrate-nfs-db`, preserving WAL backups and resuming interrupted replacements, including lazily opened databases.
- Hold the migration lock through pool initialization and keep migration failures out of automatic corruption recovery.
- Preserve local logs behavior and skip legacy NFS logs cleanup when enforcement is enabled.
## Testing
Add coverage for requirement precedence, database settings, data and backup preservation across restarts, interrupted replacement recovery, refusal of active WAL databases, migration lock waiting, and local logs remaining in WAL mode.
GitOrigin-RevId: da41ec1b58b1ee8092591cdf8b358280928ff9d4
## Why
API keys with FedRAMP issuance markers previously used commercial endpoint defaults without a FedRAMP request header.
## What changed
- Recognize `sk-proj-fedramp-` and `sk-svcacct-fedramp-` prefixes as routing hints and send `X-OpenAI-Fedramp: true`, preserving the complete key for authentication.
- Select `https://gov.api.openai.com/v1` for default OpenAI API routing and `https://gov.chatgpt.com/backend-api/` for default ChatGPT backend requests, including model discovery and analytics.
- Preserve explicit endpoint overrides, including an explicitly configured commercial default URL.
- Resolve provider routing and authentication from the same credential snapshot, and apply key-dependent routing to realtime WebSocket startup.
## Testing
Add regression coverage for prefix recognition, unchanged key storage and authorization, provider credential precedence, endpoint overrides, credential rotation, model discovery, analytics routing, and realtime request preparation.
GitOrigin-RevId: a62576ce205c34e067532b8e6c0e431f87a157e2
## What changed
Remove snapshot instruction deduplication, separate retained-assistant framing, and the associated omission-metadata special cases. Use `retain_new_instructions` in transcript rendering tests and replace the test-only Decisions snapshot adapter with the conversation adapter.
## Testing
Extend retained-source delivery and incomplete-metadata coverage to both synchronous and asynchronous context profiles. Keep Decisions HTTP, eviction, and cancellation tests exercising the conversation adapter.
GitOrigin-RevId: 3906f7d7349f73931e570ffa649377c3a235317a
## Why
The transport tests used a separate, test-only snapshot sampler instead of the production retained sampler, leaving them exercising different response ownership and cancellation paths.
## What changed
Route the transport test helper through `sample_retained` and remove snapshot execution, its active-request supersession bookkeeping, and test-only compaction compatibility fields. Simplify request-token metrics to reflect the remaining admitted-request path.
## Testing
Update tests to verify early score delivery while the retained response remains pending, WebSocket cancellation and connection reuse, and HTTP cancellation before headers or during response draining. Assert that HTTP cancellation releases classification permits.
GitOrigin-RevId: 33250103ff376af6bcd0f81ef27cdcf057f2bc5f
## What changed
- Always use the retained conversation backend for asynchronous classification; keep snapshot sampling test-only.
- Accept legacy `async_classifier_mode` values in configuration and model metadata but ignore them. Emit a startup warning when `[features.guardianv2].async_classifier_mode` is configured.
- Ignore legacy classifier mode differences when checking model-switch compatibility, and fail closed if the conversation backend is missing.
## Testing
Update coverage for legacy configuration warnings, model-switch compatibility, retained approval-review context, and conversation-based scoring.
GitOrigin-RevId: 5e8bb7e4e6e7d1589572f38bfe2498c9fa6825a0
## What changed
- Add `codex.skills.catalog.entries` and `codex.plugins.catalog.entries` histograms with `cloud` or `executor` stages and `complete`, `warning`, or `partial` status. Partial results take precedence over warnings.
- Exclude cached reads and repeated observations of unchanged failed skill discovery from metric samples.
- Mark executor skill catalogs partial when discovery fails, and clear unpublished executor plugin catalogs instead of publishing an empty result.
## Testing
Extend skill integration tests to check catalog counts and statuses, fresh discovery snapshots, partial discovery, and repeated reads without duplicate samples. Update plugin state tests to distinguish unpublished catalogs from empty discovery results.
GitOrigin-RevId: e25978ba9fce54e9660853b1d9673ddab6db5061
## What changed
- Emit `codex.turn_profile` events with finalized sampling request and retry counts when turns complete or abort, and preserve the caller's tracing span for detached extension interrupts.
- Add conversation and turn identifiers to turn and tool dispatch spans, identify tool sources, and include dispatch-to-result-ready duration on tool completion events.
- Emit `codex.skill_read.source_selected` before cache or provider access, recording the selected cloud or executor source, skill and plugin identity, resource kind, and continuation status.
## Testing
Add regression coverage for trace correlation, tool completion timing, turn profile counters on completion and interruption, detached interrupt span propagation, and skill source attribution including cached cloud reads.
GitOrigin-RevId: db78aa270bbcb8dc9e4558d202c109ad54141811
## What changed
Add the `codex-guardian-v3` crate to the Cargo workspace with a Bazel target. Expose helpers to configure the `guardian` storage namespace and construct a `LocalBoard` for the owning main thread's session ID.
GitOrigin-RevId: 3314711475a7024380a3f0beb8f5ddfc4ff19723
## Why
Provider errors with code `model_not_found` should end the turn immediately and preserve the provider's message instead of triggering retries.
## What changed
- Recognize `model_not_found` in HTTP 400, 403, and 404 responses and in streamed `error` and `response.failed` events.
- Preserve the provider message and any available HTTP status, and expose `modelNotFound` through the app-server protocol and generated schemas and SDK types.
## Testing
Add coverage for HTTP classification, statusless stream errors, and terminal failures without retries across HTTP, SSE, and WebSocket responses. Verify that `thread/read` preserves the error reported by the live notification.
GitOrigin-RevId: 88f824ac03c8c9669915b1e40c67b76c08326fbe
## What changed
Add `auto_review.timeout_ms` to configure the overall Guardian review budget, including setup and retries. Keep the default at 90,000 milliseconds; setting it to `0` disables the review deadline while preserving cancellation, retry attempt limits, and independent transport timeouts.
Carry the configured deadline through review execution and report the configured budget in review telemetry, using zero for unlimited reviews.
## Testing
Add coverage for shared setup budgets, configured timeouts, cancellation with unlimited reviews, and retry attempt limits without a deadline.
GitOrigin-RevId: 00404e0cb2f2cfaf6de183d6e27f5e4a371942a8
## What changed
- Include ready environments' configured hooks in lifecycle events and execute command hooks using each owner's shell, working directory, shell environment policy, and managed network policy.
- Resolve tool environments before `PreToolUse` and use those targets for tool hooks, execution, and permission review. Route MCP hooks by server ownership and file-copy hooks to both endpoints.
- Preserve environment, MCP server, and terminal session selectors across hook input rewrites, rejecting attempts to switch targets.
## Testing
Add regression coverage for permission-request selector preservation, MCP resource hook ownership, and file-copy hooks that rewrite paths while preserving source and target environments.
GitOrigin-RevId: 31a3a6830523965285dab451cfc866c620ef6c83
## What changed
- Read optional tool descriptions and parameter schemas for `history`, `notes`, `new_context`, and `get_context_remaining` from the acting model's catalog messages.
- Support catalog namespace descriptions for history and notes, preserving explicit empty and whitespace descriptions.
- Share catalog override handling across native tools and MCP resource helpers. Keep bundled schemas when overrides are invalid, preserve encrypted parameters, and leave tool identity and transport fields unchanged.
## Testing
Add coverage for sparse catalog serialization, schema fallback and encryption preservation, per-step tool definitions, and context tool updates when switching models. Extend outgoing-request tests to verify history and notes overrides while retaining history image attachments.
GitOrigin-RevId: 1adac8b5009f95c91adba491f20a4e2e2dc91475
