cefa060695 Approve the first Node REPL execution without a Guardian wait (#41666)
## Why

The first REPL execution should proceed while its initial asynchronous Guardian
classification is still pending.

## What changed

- Fast-approve the first `js` execution from a Node REPL-backed server while
  continuing its asynchronous classification.
- Track `js` executions separately so setup and reset tools do not consume the
  first-execution allowance.
- Apply the normal Guardian review policy to subsequent executions.

## Testing

Add coverage for browser and computer-use startup, reset, and module-directory
setup sequences, verifying that only the first `js` execution skips the wait.

0a12b855a0 Preserve Guardian authorization across history compaction (#41660)
## Why

Compaction and host-injected context can rewrite the model-visible conversation
without changing what the user authorized. Treating those updates as authorization
changes prevents Guardian from reusing an otherwise valid review.

## What changed

- Track a host-owned user-message revision separately from the conversation history
  generation.
- Advance the revision for genuine user messages and history resets, while preserving
  it across compaction and internal context injection.
- Use message content-kind metadata to distinguish host context from user input,
  conservatively treating unknown or incomplete metadata as user authorization.

## Testing

Added coverage that cached Guardian authorization survives compaction and internal
context, but is invalidated by user input and rollback.

28327355b8 Update tests for default-enabled update_plan (#41630)
## What changed

- Cover the default, explicitly enabled, and explicitly disabled states of
  `tools.update_plan.enabled`.
- Verify prompt tool lists remain consistent across requests, including when
  custom base and developer instructions are configured.
- Explicitly enable `update_plan` in existing fixtures that depend on the tool.

63d213884d Add Vim search motions to the composer (#41586)
## What changed

- Add draft-local forward and backward literal search with `/` and `?`, plus
  wrapped repeat navigation with `n` and `N`.
- Support search motions after delete, change, and yank operators, while keeping
  queries separate from the draft and skipping atomic elements and partial
  grapheme matches.
- Render and edit the query in the composer footer, highlight matches, and add
  configurable `tui.keymap.vim_search` bindings to the keymap picker and schema.

## Testing

- Cover navigation, wrapping, operator composition, repeat behavior, Unicode
  graphemes, atomic elements, query editing, paste handling, and rendering.

aaa7ed042e Harden diagnostic report uploads (#41569)
## What changed

- Send the core report event before its attachments, then upload each attachment in a separate gzip-compressed envelope linked to that event.
- Bound encoded and decoded payload sizes, truncate oversized attachment copies with format-aware handling for JSONL, and preserve attachment priority when applying size limits.
- Retry transient attachment failures within a shared upload-time budget while honoring Sentry rate-limit and retry headers without replaying the core event.
- Add APIs to prepare and send persisted report events and attachments using a stable report ID, explicit delivery outcomes, and caller-controlled retries.

## Testing

- Cover attachment retries, truncation, rate limits, rejected responses, transport failures, redirect handling, content types, diagnostic consent, and report tags.

f5636bb733 Restore thread cwd from owned settings snapshots (#41567)
## Why

Resuming a thread without an explicit `cwd` should restore that thread's latest
retained setting. Forked history can contain settings copied from another
thread, while compaction can move the latest setting outside the replay window.

## What changed

- Record the owning thread ID on new settings snapshots and only use snapshots
  owned by the resumed thread when restoring `cwd`. Older snapshots without an
  owner remain readable but do not override the startup `cwd`.
- Checkpoint the current settings after compaction and serialize checkpoints
  with settings updates so the retained history contains an accepted, current
  snapshot.
- Cover resume behavior across compaction, forks, reverts, legacy histories,
  and concurrent settings updates.

4210c08def Preserve turn lineage across goal continuations (#41562)
## Why

Automatic goal continuations should remain attributable to the turn that created the goal. External input, hook context, or goal edits can make that attribution ambiguous and must not leave stale lineage metadata behind.

## What changed

- Carry the trusted root and previous parent turn through successive automatic goal continuations.
- Invalidate stored lineage when external context reaches an active turn or when a goal is edited or cleared.
- Preserve lineage for async hook results only when they belong to the receiving turn.

## Testing

- Cover goal continuations across intervening user turns and external objective edits.
- Cover active, buffered, and externally injected hook or response context.

6478a751fd Organize bundled Rust resources under asset directories (#41477)
## Why

The `core` and `tui` Bazel targets treated nearly their entire crate trees as
compile-time data, mixing embedded runtime resources with source files and test
fixtures.

## What changed

- Move embedded resources for `core` and `tui` into dedicated `assets/`
  directories and update their `include_str!` paths.
- Restrict Bazel compile data to explicit asset and frame directories.
- Move test-only prompts into `tests/fixtures`, resolve the core prompt through
  `find_resource!`, and reuse the integration-test file glob when assembling
  Bazel test data.

## What changed

- Map each supported release platform name to its Rust target triple.
- Build multiplatform release binaries against the corresponding `rules_rs`
  platform instead of the LLVM platform definitions.
- Document that `multiplatform_binaries` accepts a subset of the declared
  release platforms.

5fc7840cf6 Refresh the TUI model picker from the app server (#41467)
## Why

The model picker can open from a cached startup catalog that no longer reflects the models available to the current account.

## What changed

- Fetch the current model list asynchronously whenever the picker opens, while showing cached choices immediately.
- Refresh an open model picker in place, preserving its highlighted model, dismissal behavior, and reasoning submenu.
- Apply accepted catalog updates to model-dependent UI, service-tier controls, and new-thread defaults. Ignore stale, failed, empty, unchanged, or account-invalidated responses.

## Testing

- Added coverage for catalog refreshes, stale and unusable responses, popup state preservation, empty choices, service tiers, and new-thread defaults.

## What changed

- Defer legacy sandbox policy projection until a working-directory change may require rebinding project-root writes.
- Keep client name and version updates from resolving filesystem paths or altering the existing permission snapshot.

## Testing

- Add regression coverage for updating client metadata with a managed, restricted filesystem policy that includes both a writable path and a nested denied path.

3c062df036 Source async user message descriptions from the model catalog (#41461)
## What changed

- Add model message metadata for built-in tool descriptions.
- Use the active step model's catalog description for `send_user_message_async`, including after a mid-turn model change.
- Fall back to the built-in description when catalog metadata is absent, while preserving an explicitly empty description.

## Testing

- Cover catalog serialization, fallback and empty-value behavior, and model changes within a turn.

03861e69ef Source proactive multi-agent instructions from the model catalog (#41457)
## What changed

- Add an optional `proactive` multi-agent mode message to model metadata.
- Use the catalog's proactive message for `Ultra` reasoning when no general mode hint is configured. A missing value falls back to the built-in proactive instructions, while an empty value suppresses the mode message.
- Keep explicit mode behavior for other reasoning efforts and refresh the applicable catalog message when the model changes.

## Testing

- Cover proactive overrides, built-in fallback, empty-value suppression, mode-hint precedence, non-`Ultra` behavior, and model switches.

2181224dad Support app targets in executor plugin hooks (#41456)
## What changed

- Admit the curated remote Browser plugin's `Stop` and `SubagentStop` hooks when its listed `browser.turn_ended` tool matches the expected connector and is enabled by app policy.
- Carry trusted app routing metadata and the MCP environment through hook registration and execution.
- Register hooks from multiple executor environments, while deduplicating cleanup calls that share an event, MCP environment, server, and tool.

## Testing

- Cover Browser and Computer Use cleanup through separate MCP routes, including user- and managed-policy disablement.
- Verify routing metadata, environment selection, multi-environment registration, and target deduplication.

62b458c931 Block goals after repeated execution host failures (#41454)
## What changed

- Track failed `exec` attempts whose handler ran for each active goal.
- Mark the goal as blocked after three qualifying failure turns.
- Reset the failure streak when any tool succeeds, and keep failures from carrying over to a replacement goal.

## Testing

- Cover failure classification, streak resets, goal replacement, and end-to-end goal blocking through the app server.

48e22a5fa0 Report code mode host request durations (#41452)
## Why

Code mode wall time should measure the host operation itself, without including
client-side response delays or idle time between requests.

## What changed

- Measure each execute, wait, and terminate request in the code mode host.
- Carry the duration through the stdio and gRPC protocols and use it for
  model-visible wall time.
- Emit a structured `codex.code_mode.host_timing` event correlated with the
  conversation, turn, tool call, and cell.

## Testing

- Cover successful and failed execution timing, delayed response reads,
  repeated waits, termination, and missing cells across stdio and gRPC.
- Verify timing survives protocol serialization and is reflected in app-server
  model output and structured telemetry.

## What changed

- Allow `request_user_input` for optional questions that materially improve work quality.
- Continue with best judgment when the tool returns no answers.
- Keep permission requests, escalations, and other required input out of the tool; ask one concise plain-text question when progress cannot safely continue.
- Update the collaboration-mode preset test for the revised direct-question guidance.

eec4a23cb1 Support openai/elicitation form requests (#41447)
## What changed

- Advertise `openai/elicitation` form support when the client declares an
  object-valued `form` capability, without deriving it from the legacy
  `openai/form` capability.
- Handle `openai/elicitation/create` requests in `form` mode and forward their
  metadata and opaque schema through app-server as `openaiForm`, preserving
  `x-openai-*` annotations.
- Keep legacy form handling independent and have the TUI automatically decline
  the new form requests it cannot render.

## Testing

- Add an app-server round-trip test for capability negotiation, request
  forwarding, and accepted responses.
- Extend MCP capability filtering coverage for `openai/elicitation.form`.

0ae94fdd49 Respond to terminal queries from TTY subprocesses (#41436)
## Why

Programs running in a PTY can block while waiting for replies to terminal
queries.

## What changed

- Intercept device-status, window-size, cursor-position, and DEC private-mode
  queries from TTY subprocess output and write bounded responses to the
  subprocess input.
- Remove handled queries from the output stream while preserving other escape
  sequences and output, including queries split across chunks.
- Apply the responder to both direct and driver-backed TTY process spawning.

## Testing

Added tests for driver-backed query handling and for a PTY subprocess that
waits for a cursor-position response before exiting.

c2abf869d5 Run executor hooks for interrupted turns (#41432)
## Why

Executor-scoped cleanup hooks need to observe an interrupted turn as well as a
normally completed one.

## What changed

- Allow bundled executor plugins to register the allowlisted `Interrupt` hook
  alongside `Stop`, while preserving multiple allowed hook entries from the
  selected executor environment.
- Run interrupt hooks with the interrupted turn's last step discovery and turn
  metadata. Turns without a step context do not reuse discovery from an earlier
  turn.
- Keep executor-scoped interrupt hooks asynchronous and omit public hook
  lifecycle events for them, matching executor `Stop` hook behavior.

## Testing

Added coverage for hook filtering and registration, interrupt execution and
metadata propagation, environment selection, and turns without a step context.

0d22692962 Retain the last selected step context for each turn (#41429)
## What changed

- Store the most recently captured execution `StepContext` in the active turn state.
- Keep speculative model-fallback captures from replacing that context, and update it only when the fallback is selected for remote compaction.
- Preserve the retained context when a turn completes or is interrupted.

## Testing

- Add coverage for completed and interrupted turns, successful primary compaction, fallback compaction, and interruption while a fallback is running.

## What changed

- Treat a surviving full world-state snapshot as a context baseline when a fork removes the associated user message.
- Restore the previous turn settings and reference context from that baseline, without treating the segment as a user turn for rollback.
- Ignore partial snapshots and full snapshots superseded by compaction.

## Testing

- Cover resumed rollout reconstruction with removed task messages, partial snapshots, and compaction.
- Verify nested agents inherit developer instructions and environment context exactly once across history modes and compacted histories.

- Preserve conversation order and role or tool attribution while applying separate per-entry limits for messages, ordinary tools, and Node REPL-backed outputs.
- Make tool calls, tool outputs, and reasoning independently configurable, and expose transcript collection without requiring section composition.
- Register the transcript contributor in a process-wide default registry that retains no request state.

- Apply the most restrictive limit when plugin and user policies overlap, while keeping approval policy independent.
- Carry the effective MCP output budget in conversation history so tool output, post-tool hook responses, and resumed sessions use the same truncation limit.

## Testing

- Cover configuration parsing, serialization, schema validation, and plugin policy merging.
- Cover MCP output below and above the configured limit, post-tool hook responses, and session resume.

3ae4225b17 Restrict cloud task credentials to trusted origins (#41403)
## Why

Cloud task requests can use saved ChatGPT credentials, so their destination must be constrained before authentication is loaded or any request is made.

## What changed

- Validate `CODEX_CLOUD_TASKS_BASE_URL` against trusted ChatGPT HTTPS origins on port 443 and reject URLs containing user information, queries, or fragments.
- Disable redirects for cloud task backend and environment-discovery clients so credentials are never forwarded to a redirect destination.
- Normalize the validated base URL before configuring authentication and HTTP clients.

## Testing

Add a CLI integration test that verifies a custom cloud backend is rejected without receiving a request, while the staging origin continues to use explicit token authentication.

## What changed

- Re-run the HTTP headers helper after a same-origin `POST` receives a `401` or `403`, and retry the request once when the effective headers changed.
- Share refreshes across concurrent rejected requests, retain the previous headers when refresh fails, and keep the retry within the original timeout.
- Allow helpers to supply `Authorization` while preserving explicit OAuth or bearer credentials, OAuth insufficient-scope challenges, and redirect safety checks.

## Testing

bb998aeb8e Refresh runtimes for remote plugin state changes (#41396)
## Why

Enabling, disabling, or reinstalling a cached remote plugin can change its
effective MCP servers, hooks, and skills without materializing a new bundle.
These transitions need to invalidate plugin consumers just like bundle updates
and removals do.

## What changed

- Report a unified set of changed remote plugins and their affected
  capabilities for materializations, removals, and installed-state changes.
- Derive enablement and reinstall changes by comparing installed snapshots,
  while keeping materialization metadata separate for hook trust handling.
- Preserve removal notifications even when stale cache cleanup fails, and use
  all reported changes to refresh loaded plugin state and runtime consumers.

## Testing

Added coverage for cached plugin enablement, disablement, removal, and
reinstallation, including removal when cache cleanup cannot complete.

## Why

Managed configuration can disable resumable unified execution while leaving shell tools enabled. This should not remove command execution entirely or grant access to retained processes.

## What changed

- Keep `exec_command` available in completion-only mode when `unified_exec` is disabled.
- Remove `tty`, `yield_time_ms`, `session_id`, and `write_stdin` from that mode, and add a `timeout_ms` argument.
- Terminate one-shot commands on timeout or turn cancellation, reporting timed-out commands with exit code 124.

## Testing

- Cover classification metadata across retries, connection reuse, concurrent samples, auth refresh, and consecutive owning turns.

e4d0ba4e92 Support configurable timeouts for thread shell commands (#41384)
## What changed

- Add an optional `timeoutMs` parameter to `thread/shellCommand` and propagate it to user shell execution.
- Preserve the one-hour default when the parameter is omitted or `null`, allow longer deadlines, and treat `0` as an immediate timeout.
- Reject negative or otherwise invalid values before execution. Timing out an auxiliary shell command leaves its active turn running.

## Testing

- Cover default, extended, immediate, invalid, standalone, active-turn, and interruption behavior.

4ee04c0aa5 Clarify proactive multi-agent delegation guidance (#41380)
## What changed

- Limit the proactive-mode override to earlier developer instructions that require an explicit delegation request.
- Preserve user requests as higher-priority guidance.
- Encourage root agents and subagents to delegate parallel work when doing so could improve speed or quality.

## Testing

- Update the multi-agent world-state snapshot for the revised proactive-mode message.

8bcac28f93 Preload plugin recommendations during session startup (#41375)
## Why

Fetching plugin recommendations while building the first-turn context delays that
context when the recommendation catalog is not already cached.

## What changed

- Start fetching recommendations during session initialization, in parallel with
  MCP and plugin setup, and reuse the in-flight request when building context.
- Centralize the feature checks that enable plugin recommendations.
- Prevent an invalidated recommendation request from repopulating the cache after
  a newer request has completed.

## Testing

Added coverage for startup feature gating, reuse of the in-flight fetch, legacy
behavior when recommendations are unavailable, and cache invalidation races.

5ed294d49d Match Windows shell guidance to the executor platform (#41368)
## What changed

- Include Windows safety guidance in the `exec_command` tool description when a
  single ready environment reports Windows as its executor platform.
- Omit that guidance when the selected executor reports a non-Windows platform.
- Preserve the host-based behavior when platform information is unavailable or
  the tool can target multiple environments.

## Testing

- Cover Windows, non-Windows, unknown-platform, and multi-environment tool plans.
- Verify remote environments expose guidance that matches their target OS.

7e41be641e Restrict async user messages to questions (#41365)
## What changed

Update the `send_user_message_async` tool guidance to reserve it for questions
that require missing information, preferences, constraints, clarification, or
approval. Ask models to keep these questions concise, understandable, and at
an appropriate level of abstraction for the user and task.

8faf7252f0 Test resuming compressed shared rollouts (#41364)
## What changed

Add an end-to-end core test that compresses a parent and forked child rollout,
then resumes the child through paginated history loading. Verify that the
resumed model input:

- retains the persisted compaction checkpoint and inherited history;
- includes child history through the fork boundary;
- excludes obsolete pre-checkpoint and post-fork parent messages; and
- reads the compressed ancestor without materializing its JSONL file.

f4f85add41 Measure Codex home usage at app-server startup (#41360)
## What changed

- Scan regular files under `CODEX_HOME` in a background blocking task when
  standalone app-server metrics are enabled.
- Record `codex.app_server.codex_home.size_bytes` for the entire home and the
  `sessions` and `archived_sessions` subdirectories.
- Avoid following symlinks, discard incomplete scans, and cancel scanning during
  shutdown.

1cc81ca89a Support compression for shared rollout lineages (#41357)
## Why

Rollout compression skips files that participate in paginated fork lineages because lineage readers rely on byte offsets into the original JSONL. This prevents shared rollout history from being compressed.

## What changed

- Add a seekable rollout reader that preserves logical JSONL offsets for plain and zstd-compressed files without materializing compressed data beside the rollout.
- Use the reader for lineage validation, model-context replay, and SQLite history projection, including when compression races with a read.
- Add the opt-in `local_thread_store_shared_compression` feature. The default mode continues to leave shared lineages uncompressed for compatibility, while the new mode includes referenced sources and fork pointers.
- Record the uncompressed size in new zstd frames so common prefix-bound checks can avoid decoding the full file.

## Testing

Add coverage for seekable compressed reads, prefix validation across zstd frame shapes, compressed lineage replay and projection, concurrent forks, and compression-mode behavior.

39507eea53 Reject NUL bytes in reviewed terminal input (#41354)
## Why

Manual terminal-input approvals shell-quote the proposed input, which cannot
preserve NUL bytes for an accurate review.

## What changed

Reject terminal input containing a NUL byte before creating an approval request
or sending any of the input to the terminal.

## Testing

Extend the unreviewable-input integration test to cover both oversized input
and NUL-containing input, and verify that rejected input is not executed.

## What changed

- Assign type-prefixed IDs to Guardian classifier input items before sending the request, preserving existing IDs and reusing generated IDs across WebSocket retries.
- Add a prefixed ID to the memory phase-one user message.

## Testing

- Verify retried Guardian requests contain the same unique, prefixed item IDs.
- Verify the memory phase-one request includes a prefixed user-message ID.

92f887ec35 Use refreshed MCP tool caches during binding capture (#41344)
## Why

An MCP binding can wait for one server while another connection updates a
shared tool catalog. Preferring the catalog captured before that wait can omit
newly available tools from the first model request.

## What changed

- Recheck the current MCP tool catalog before using the captured fallback.
- Keep the captured catalog when it expires during the wait, while honoring a
  server that disables catalog caching.

## Testing

- Cover a shared Apps cache populated by a peer while binding capture waits.
- Cover cache opt-out while capture waits for another server.

7625343977 Preserve cached MCP tools during binding capture (#41336)
## Why

Binding capture can wait for multiple MCP servers concurrently. During that wait, a tool catalog may be published by another connection or expire after it has already allowed a server to remain dormant. Re-reading only the current cache could omit those tools or trigger unnecessary startup.

## What changed

- Retain the cached catalog that permits lazy startup for the duration of binding capture.
- Recheck the cache after the optional startup grace so catalogs published while waiting are included.
- Add regression coverage for catalogs published during startup and catalogs that expire while another server is resolving.

## What changed

- Mark `clock.curr_time` and `clock.sleep` as built-in control tools so their calls emit control-tool analytics.
- Cover completed, failed, and interrupted calls, verify analytics omit tool arguments and output, and keep the calls out of the dynamic-tool count.
