## What changed
- Update the workspace, Bazel toolchain and lockfile, CI and release workflows, and Windows setup script from Rust `1.95.0` to `1.99.1`.
- Adapt Rust code to the updated toolchain and Clippy lints, including `try_update` for atomics, `as_chunks` for fixed-size slices, and targeted allowances for generated tonic services.
- Refresh the halfwidth sound mark rendering snapshot to use literal characters in debug output.
GitOrigin-RevId: 5852029f687436dc814c2bca68141ee1f4a67d49
## Why
Title and content searches exclude attached threads, preventing clients from finding their saved conversations alongside ordinary threads.
## What changed
- Add `includeAttachedThreads` to `thread/list` and `thread/search`. For `thread/list`, require a non-empty `searchTerm` and preserve the usual provider and source filters.
- Expose `attachedToThreadId` on thread responses to identify the owning parent independently of fork and subagent lineage.
- Support inclusive searches through SQLite and filesystem fallback, repairing missing database entries with saved thread names during title searches.
## Testing
Add regression coverage for opt-in title and content searches, attached-parent metadata after restart, default search filters, filesystem searches without SQLite, and discovery and repair of unindexed title matches.
GitOrigin-RevId: ac12ec3c730ad7f1722bdf8e21600d17f12017f0
## What changed
Keep untrusted project configuration and MCP servers disabled in exec runs, even with `--sandbox workspace-write`, and warn when project configuration is disabled.
Add `--trust` to `codex exec` and `codex review` to save project trust for the current and future chats, including MCP commands outside the sandbox. The grant persists with `--ephemeral`, refuses explicitly untrusted projects, and cannot be combined with `--ignore-user-config`.
Pass the working directory as a configuration default so embedded server startup does not implicitly grant trust. Preserve the selected `--oss` provider across configuration reloads.
## Testing
Extend CLI parsing and MCP integration coverage for explicit trust, persistence across ephemeral runs, disabled project configuration with write access, and rejection of conflicting or explicitly untrusted settings.
GitOrigin-RevId: b57f4f8829f98d77c5487fa8405c7f29b5d70d0c
## What changed
Allow experimental clients to request `deferOutput: {"commandExecution": true}` in `thread/items/list` for a specific `turnId`. Completed commands with a recorded completion time, exit code zero, and nonempty saved output return `outputDeferred: true` and `item.aggregatedOutput: null`. Clients can retrieve the complete output through `thread/items/read` using the turn and item IDs.
Keep full output by default and for listings across turns. Make conversion from `ThreadItemEntry` to `ThreadItem` fallible so Rust consumers detect deferred output instead of treating an incomplete item as complete.
## Testing
Add integration coverage for experimental capability gating, default and disabled options, command status and output eligibility, listings across turns, deferred-item conversion, and full output retrieval by item ID.
GitOrigin-RevId: d6bfac34bb68f7e3b327fd5553270ed6d0fe87cf
## Why
`codex exec --output-last-message` wrote through a pathname after tools finished, allowing sandbox activity to redirect the final write by replacing that path with a symlink. The related risk is described in https://github.com/openai/codex/pull/25956.
## What changed
- Open the destination before starting the agent and retain its handle until the final write.
- Reject symlinks, Windows reparse points, and multiply linked files; verify that the pathname still identifies the bound file before truncating and after writing.
- Propagate output errors so the command fails when the destination cannot be opened or written safely.
- Preserve inherited Unix output streams, FIFOs, devices, and Windows `NUL` support, while avoiding duplicate final answers when human output targets stdout.
## Testing
Add regression coverage for sandbox-created symlinks across consecutive invocations, redirected stdout, delayed truncation, hard links, replaced paths, and Windows stream binding and filesystem identity checks.
GitOrigin-RevId: 4a31bd28a5eb2d0a9e200cb658eb7d19dc93e933
## What changed
- Add `currentAccountOnly` to `thread/list` and `thread/search`, defaulting to `false`, and enable it for TUI history discovery, resume pickers, and task mentions.
- Mark newly created threads as account-scoped and require each recorded creator user or account ID to match the current login. Older threads and threads without creator IDs remain shared; API-key logins continue to see all local history.
- Preserve account scope through resume and revert, including fallback to original rollout metadata when an older binary drops the marker. Forks receive new-thread scope.
- Skip unreadable rollout headers in scoped discovery and filter search candidates before reading snippets. Direct access by thread ID remains available.
## Testing
Add coverage for account matching, shared legacy history, list page refilling, search pagination, API-key visibility, and scope preservation across reverts. Extend rollout lookup coverage to compressed active and archived files.
GitOrigin-RevId: aa374f5e69165be5a71c0716ded1b105f5fb51e0
## Why
Cyber access program selection was restricted to the `openai` provider ID, preventing custom providers from accepting explicit program selections.
## What changed
- Add `capabilities.cyber_access_programs` to provider configuration and preserve it through remote thread configuration. Default to enabled for `openai` and disabled for other provider IDs, with explicit overrides taking precedence.
- Use the capability when forwarding `access_programs.cyber` and determining Daybreak availability in exec and the TUI. Refresh TUI eligibility when the server changes the selected provider.
- Preserve authentication, API-key feature gates, and catalog access checks; the capability does not grant program access.
## Testing
Add coverage for capability defaults and overrides, configuration round trips, custom-provider requests with both authentication types, API-key feature gating, compaction, WebSocket response reuse, exec selection, and TUI provider changes.
GitOrigin-RevId: 579f7c33c9e857ff5fedd08311aa8e3129740c1f
## Why
Managed command policies need to require a human decision independently of automatic review, hook allowances, and saved approvals.
## What changed
- Support `decision = "prompt-user"` in managed `requirements.toml` prefix rules, requiring a fresh, one-time human decision for matching commands.
- Add experimental `humanCommand` approval requests for clients advertising both `experimentalApi` and `requiredHumanApproval`. Accept only `accept`, `decline`, or `cancel`; reject commands when no capable client is available.
- Restrict responses to capable clients that received the request, and replay pending prompts to compatible clients on reconnect.
- Enable the capability in the TUI and update protocol schemas and client bindings.
## Testing
Add coverage for fresh decisions overriding saved allowances, hook allowances, and automatic review, plus child-thread approval routing and rejection of responses from incompatible or unrelated clients.
GitOrigin-RevId: 0b95ff6aab7f8a04b7298c8a4329d1fddf6a603e
## Why
`codex exec` recovers turn items at completion because item notifications can be dropped under backpressure. This recovery needs to respect the thread's history mode.
## What changed
For paginated threads, fetch every page from `thread/items/list`, scoped to the completed turn. Preserve items already present in the completion notification when merging the recovered history, and stop recovery if a cursor repeats. Keep `thread/read` recovery for other history modes.
## Testing
Add regression coverage for recovering a final answer across multiple item pages and for a failed fork recovering only its own turn.
GitOrigin-RevId: f005ca2cf9d8313bbbf32ed4c228ebb5e51428a2
## 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
- Use the managed configuration loader in CLI, exec, TUI, and app-server configuration flows so `requirements.toml` can select a config server.
- Sign in to the config server when needed during interactive TUI startup and CLI login, reload configuration after CLI sign-in, and clear config-server credentials on CLI logout.
- Preserve the app-server's config-server settings and refresh worker across OpenAI login and logout.
- Require config-server settings to be applied when loading CLI and doctor configuration.
## Testing
Add app-server integration tests using a local HTTPS config server to verify managed provider and instruction settings at startup, preservation across API-key login and logout, and cache reuse after restart and thread resume.
GitOrigin-RevId: 27ee81f7943d2290a5c3fcc0ac556579ec63f8b4
## What changed
- Add nullable `startedAtMs` and `completedAtMs` fields to `ThreadItem` in live notifications and turn history. Values are Unix milliseconds when recorded.
- Preserve recorded item times through history reconstruction, pagination, and resume, including command start times recorded during approval.
- Separate the Rust item payload into `ThreadItemPayload` while keeping the JSON payload flat, and update consumers, schemas, and generated TypeScript and Python types.
## Testing
Extend coverage for timestamp serialization, history reconstruction, paginated reads and resume, and persisted Python SDK items.
GitOrigin-RevId: ecbcee95af52db7c807b46a6e9deb30e5fba1f80
## What changed
- Rename ChatGPT-specific bundle loaders to `chatgpt_config_bundle_loader*` and use managed-config terminology for shared loader plumbing.
- Pass `Config` directly when updating the app-server's managed configuration loader.
- Share configuration loading, logging setup, and result handling between browser and device-code login.
- Expose the CLI cloud-config helpers and `provider_uses_first_party_auth_path` through their library APIs.
## Testing
Extend CLI login coverage to verify that `forced_login_method="api"` rejects both `login` and `login --device-auth` while preserving saved API-key credentials.
GitOrigin-RevId: 9e8fa6110dc80882ba365e550b48ac77da604940
## What changed
- Add `attachToSource` to `thread/fork` to persist a fork attached to its source without emitting `thread/started`. Attached forks require local storage and cannot use `ephemeral` or `deferGoalContinuation`.
- Hide attached threads from ordinary listings and add `attachedToThreadId` to `thread/list` for explicit discovery, including empty threads. Keep this relationship separate from spawned-agent parent and ancestor filters.
- Persist attachment metadata in rollouts and SQLite so it survives restarts and database recovery. Reject source deletion until its attached threads are deleted.
## Testing
Add coverage for legacy and paginated history, restart and missing or corrupt database recovery, filtered listings and pagination, resume, conflicting options, and deletion safeguards across store instances.
GitOrigin-RevId: 589f3174fc36f6054e75d65818360695645a5913
## What changed
- Update Cargo and Bazel toolchain pins, CI and release workflows, and Windows setup from Rust `1.95.0` to `1.99.1`.
- Adapt Rust code to updated APIs and lint requirements, including `try_update` and `as_chunks`, and refresh the halfwidth sound marks snapshot.
- Update `webpki-root-certs` from `1.0.5` to `1.0.10` in the Cargo and Bazel lockfiles.
GitOrigin-RevId: e1aaed63b7e72bb8c8bbe25b32c6329c9a37b6c3
## Why
MCP tool calls reported every aborted approval as "user cancelled MCP tool call", including interrupted requests and automatic cancellations in `exec` mode.
## What changed
Carry `user`, `interrupted`, or `non_interactive` cancellation reasons through MCP approval metadata and resolution. Mark explicit TUI cancellations as user actions, interrupted requests as interruptions, and automatic `exec` cancellations as non-interactive.
Use the reason to report when a call was cancelled before approval or because interactive approval is unavailable in `exec` mode. Preserve the existing cancellation message for clients that omit the reason.
## Testing
Update tests to verify that a closed approval response carries the interruption reason and that `exec` cancellation responses include the non-interactive reason.
GitOrigin-RevId: be2a5f7fef539b5db2add53b46aea27e2b8a66fc
## What changed
- Remove feature-flag checks from managed worktree creation and repository-aware session discovery, while retaining local workspace and trust checks.
- Make TUI voice availability follow platform support instead of `features.realtime_conversation`.
- Ignore `features.worktrees` and `features.realtime_conversation` configuration overrides, warn when managed requirements reference them, and hide both flags from `/experimental`, including catalogs from older servers.
## Testing
Add coverage for ignored configuration overrides and managed requirements, and update session filtering, worktree grouping, and experimental feature discovery tests for the retired flags.
GitOrigin-RevId: 1d64e890e6e2f8a78926a9ea163126c0890b068e
## Why
Clients need a way to update individual turn metadata entries without replacing the existing client metadata map.
## What changed
Add the experimental `responsesapiClientMetadataPatch` field to `turn/start` and `turn/steer`. Patches add or overwrite entries while retaining other keys and apply after `responsesapiClientMetadata` when both are supplied. The existing field retains replacement semantics, including clearing unprotected entries with an empty map.
Continue protecting reserved metadata keys and preserving targeted `misalignment_override` continuations across updates.
## Testing
Extend the app-server metadata integration test to cover replacement and patch steering, patch precedence at turn start, preservation of unrelated entries during patches, and protection of targeted continuations.
GitOrigin-RevId: 8c4da3ba1b87329da20b5295846bdcf3a88126de
## Why
Blocking rollout reads can continue decompressing and scanning history after the calling async task is dropped.
## What changed
Propagate caller cancellation through rollout readers, prefix validation, model-context scans, history materialization, and working-directory lookup. Check cancellation during compressed input and output, bounded reads, seeks, and between history records. Return an error on cancellation so partial history cannot be mistaken for a complete read.
## Testing
Add regression coverage for dropping a caller during decompression, cancelling compressed input and output (including skippable frames), cancelling reads and seeks on plain and decoded snapshots, and cancelling history materialization between records.
GitOrigin-RevId: e3dac952789b53402f2a5f17c2a2232506feb9d6
## What changed
- Default `features.api_key_cyber_access_programs` to `true` and allow `codex exec` to select Daybreak with an OpenAI API key. Select the advertised standard program when `daybreak=false`, while respecting explicit feature opt-outs.
- Resolve API-key eligibility for TUI background turns from the target thread's feature settings, including project opt-outs. Omit access-program overrides when the server cannot report those settings.
- Preserve automatic server treatment for unlisted models and missing or empty Cyber program metadata in exec and TUI. Continue rejecting Daybreak when a nonempty program list does not offer it.
## Testing
Update regression coverage for API-key Daybreak selection, the off override, explicit opt-outs, resumed sessions, target-thread settings, and missing model metadata.
GitOrigin-RevId: f3cf7bd95a2754d4b4281bc70b18c7da4b177552
## Why
Restoring unnamed thread permissions after configuration loading leaves network proxy initialization and permission validation using the configured default. A saved read-only thread should also resume when that default is incompatible with current managed requirements.
## What changed
Apply eligible saved permission profiles during configuration loading, before network preparation and final validation. Keep explicit permission overrides and managed requirements authoritative, preserve managed deny-read restrictions, and reject saved external enforcement or materialized filesystem grants. Include the saved profile in the app-server's prepared resume configuration state.
## Testing
Add regression coverage for resuming saved read-only permissions with an incompatible full-access default and for retaining managed, remembered, and newly approved network domains in the restored profile's proxy allowlist.
GitOrigin-RevId: 73e32b0a31ac678fd3f60a8ccf8fa9df627f16c3
## What changed
- Use the standard shell executor and remove the zsh fork escalation runtime, `codex-execve-wrapper`, and `shell-escalation` crate.
- Ignore `shell_zsh_fork` and `unified_exec_zsh_fork`, emit migration notices for legacy configuration, and warn when ignoring managed requirements for these flags.
- Keep the active session's `apply_patch` alias directory readable under restricted filesystem permissions.
## Testing
Add coverage for legacy configuration startup and shell execution, migration notice rendering, active alias directory selection, and nested `apply_patch` execution while other files in `CODEX_HOME` remain unreadable.
GitOrigin-RevId: 43af461fea32b4980550ee7237effd2bc0646ed8
## Why
Clients displaying a saved manual thread order need to list the remaining threads without repeating those already loaded separately.
## What changed
Add optional `excludedThreadIds` to `thread/list` and the generated protocol bindings. Apply exclusions before the result limit, refilling pages until the requested limit is reached or history is exhausted while preserving existing filters and ordering. Clients must send the same exclusions on each page.
Accept up to 100 entries, counting duplicates toward the bound. Reject invalid IDs or oversized lists with JSON-RPC error `-32602` rather than truncating them. Omitted, null, and empty lists preserve existing behavior.
## Testing
Add integration coverage for page refill across database-only and scan/repair paths, archived threads, sort directions, and project/section scopes. Cover duplicate and unknown IDs, the 100-entry boundary, invalid input, and preservation of section order.
GitOrigin-RevId: e9a884e642ae25d166aff7e275469d1d43179c6c
## Why
Clients starting delegated work need to attribute descendant turns to the original turn and retain that attribution through completion and history reads.
## What changed
- Accept optional `parentTurnId` and `rootTurnId` in `turn/start`, and expose `rootTurnId` on returned turns and lifecycle notifications.
- Default new turns to their own root when none is supplied. Preserve the active turn's root when steering, ignoring incoming lineage fields.
- Carry root IDs through completion, interruption, recovery, and fork boundaries, and persist them for paginated history reads. Leave unknown roots null in older history.
- Update protocol schemas and generated TypeScript and Python bindings.
## Testing
Extend coverage for default and explicit roots, steering without changing lineage, interrupted and recovered turns, history reads after restart in both history modes, nested fork pagination, and compatibility with older database writers.
GitOrigin-RevId: f1a570a12bd11742929fd2e8b017e5d35aa07dcb
## Why
Bubblewrap discovery probes executables before confinement. Excluding only the command's current directory leaves candidates in other writable roots eligible to run outside the sandbox.
## What changed
- Filter canonical `PATH` candidates using the filesystem policy and effective user permissions, including writable ancestors, symlinked roots, and full-disk write access. Preserve protected system installations while rejecting replaceable paths.
- Select the launcher with the command's permissions before the proc-mount preflight, retaining the bundled bubblewrap fallback.
- Use the effective permission profile and policy working directory for startup warning probes.
## Testing
Add unit coverage for writable roots, symlinks, read-only carveouts, replaceable parents, and full-disk policies. Add Linux integration tests showing writable `bwrap` candidates are neither probed nor launched, including when the command runs in a workspace subdirectory or uses managed networking with full-disk write access.
GitOrigin-RevId: 188c9f45e727eaace062f5abb1205dc23fdf3c51
## What changed
Add `features.cli_daybreak`, disabled by default, to gate Daybreak controls and automatic access-program selection in the TUI and `codex exec`. Apply the gate to resumed sessions and background task turns, and hide `/daybreak` when disabled. Explicit `--cyber-access-program` overrides remain available.
## Testing
Extend tests to cover disabled controls, history replay, foreground and background turn requests, exec resume/fork behavior, and explicit access-program overrides with the feature disabled.
GitOrigin-RevId: ae96a4a8c7ab97c619716b9f39ea9f295df6e5a6
## What changed
Remove `initial_messages` from `SessionConfiguredEvent` and the corresponding schema. Stop attaching replay history to startup events for resumed or rejoined threads, and remove `InitialHistory::get_event_msgs`.
## Testing
Update the MCP resume test to verify persisted tool events through `load_history`, and retain coverage that resumed requests include prior conversation items.
GitOrigin-RevId: 54b72bc44423c9b1ef2051891ef392c0ede32fe5
## Why
`codex exec` and the TypeScript SDK need a way to request a Cyber access program for an individual turn. Resuming with an API key can also leave compaction using a saved program that the current credentials cannot access.
## What changed
- Add `--cyber-access-program` with `standard`, `daybreak_blue`, and `daybreak_red`, and expose the equivalent `cyberAccessProgram` turn option and `CyberAccessProgram` type in the TypeScript SDK.
- Apply explicit selections to new, resumed, and prompted fork turns. Override automatic Daybreak selection for that turn without changing the saved choice. Reject the flag for review and forks without a prompt.
- Filter Cyber programs by the built-in OpenAI provider when starting turns and restoring previous-turn settings for compaction.
- Allow previous-model compaction fallback with API-key authentication, comparing both model and program so a program change can trigger a retry with the current pair even when the model is unchanged.
## Testing
Add CLI help, argument parsing, exec, and SDK coverage for per-turn selection and unsupported commands. Extend core tests for API-key compaction retries, denied explicit selections, custom-provider filtering, remote compaction, and WebSocket response reuse.
GitOrigin-RevId: 586f25b621924f3bc509c9a39b39fe2020ff9cd2
## What changed
- Add the `daybreak` configuration key, defaulting to `false`, with per-invocation overrides such as `-c daybreak=true`.
- Resolve access programs from the model catalog, preferring `daybreak_blue` over `daybreak_red` when enabled and selecting advertised `standard` access when disabled for signed-in ChatGPT accounts. Require the OpenAI provider, a signed-in ChatGPT account, and a compatible model to enable Daybreak.
- Save the choice for new persistent threads and inherit it on resume and fork, including ephemeral forks. Explicit CLI overrides apply only to the current invocation.
## Testing
Add protocol tests for advertised-program selection and exec integration tests for account and provider restrictions, saved choices, ephemeral forks, and invocation-only overrides.
GitOrigin-RevId: ac955f08b5a891e720cfc5f67fabb7b0f6d32bb8
## Why
Private IP destinations always bypassed inherited upstream proxies, preventing their use for private networks reachable through an upstream VPN proxy.
## What changed
- Add `codex exec-server --proxy-private-ips-via-upstream`, also configurable with `CODEX_EXEC_SERVER_PROXY_PRIVATE_IPS_VIA_UPSTREAM=true`. The setting defaults to disabled.
- Allow permitted RFC 1918, carrier-grade NAT, and IPv6 unique-local destinations to use an applicable upstream proxy. Loopback and link-local destinations retain direct routing, and destination access policy still applies.
- Keep connections direct when no valid upstream proxy applies or `allow_upstream_proxy=false`. Errors after selecting an upstream proxy do not trigger a direct retry.
- Rename `ExecServerRuntimePaths` to `ExecServerRuntimeOptions` and carry the routing setting from executor startup into the managed network proxy.
## Testing
Add routing coverage for private address ranges, special-use addresses, and public targets with the option enabled and disabled. Verify that HTTP and CONNECT requests still enforce destination allowlists and denylists, and update the CLI help snapshot.
GitOrigin-RevId: b7c9cc7da0e0f545694a6521b74c9b36b7b92769
## Why
Application network restrictions need to cover clients created by the TUI and `codex exec` before embedded app-server startup, and remain effective when configuration is rebuilt.
## What changed
- Introduce `EmbeddedNetworkPolicy` to share live policy between caller-owned transports and the embedded app-server.
- Apply loaded requirements before creating telemetry, background HTTP clients, and executor connections. Limit authentication and cloud configuration bootstrap requests to exact endpoints under local policy.
- Preserve the shared policy across TUI session changes, permission-profile rebuilds, and worktree cloud loaders so existing clients observe policy reloads and failures.
- Document application network policy behavior and transport coverage.
## Testing
Add regression coverage for policy activation, reload failure and recovery, retained policy across TUI rebuilds, rejected OAuth and cloud-policy redirects, and workspace network restrictions with `CODEX_API_KEY`. Also cover retaining the caller-selected project during embedded startup.
GitOrigin-RevId: 629009f087b8cb21fc34a1ee7ea6fe95d9e0f2b5
## What changed
Set `turn_trigger` to `exec` for exec turns and `user` for TUI turns when sending `turn/start` requests.
## Testing
Extend exec resume and embedded TUI tests to check `x-codex-turn-metadata`, including thread IDs, the TUI turn ID, and the expected triggers. Update the active-turn steering test to verify that user steering preserves the original `goal` trigger.
GitOrigin-RevId: 56125f64b5c47e7c538663d748b3a5f404e68316
## What changed
- Accept `disabledPluginIds` in `thread/settings/update` and `turn/start`. A supplied list replaces the saved selection; omission or `null` preserves it, and `[]` clears it.
- Return the selection in thread start, resume, and fork responses and `thread/settings/updated` notifications. Update generated schemas and client types.
- Restore disabled plugin IDs from the history retained at the requested fork boundary, preserving explicit overrides.
The selection persists across resume but does not yet filter plugin capabilities.
## Testing
Add coverage for replacing, preserving, and clearing selections without inference; turn-start notifications; resume; and fork boundaries across legacy and paginated history, with loaded and restarted parents. Add a core regression test for history restoration and explicit clearing.
GitOrigin-RevId: 654a8c2a0527228d422c0dd4919228447e2663db
## Why
`--worktree` previously supported only `codex exec` and `codex exec fork`. Interactive sessions need the same managed checkout support, with configuration and policy resolved for the destination before starting a turn.
## What changed
- Enable `codex --worktree` and `codex fork --worktree <session-id>` behind the `worktrees` feature, restricted to local sessions. Interactive forks require an explicit session selector.
- Resolve interactive and exec worktree forks from the session's latest saved working directory unless `--cd` is supplied. Keep relative `--add-dir` paths anchored to the invocation directory.
- Load interactive destination configuration before telemetry and login policy initialization, and bind checkout ownership before the first turn.
- Reject explicitly untrusted sources, including when destination cloud policy or refreshed configuration reveals distrust. Retain unbound interactive checkouts after startup failure and report manual recovery instructions.
## Testing
Add CLI integration and TUI tests for startup and named forks, destination instructions and configuration, ownership before the first request, trust enforcement, and retained-checkout recovery. Extend exec coverage for saved fork directories, explicit `--cd`, relative writable roots, and cloud policy rejection.
GitOrigin-RevId: 371583f7feca73b218a4ff188b2b85812c8439e6
## What changed
- Add the macOS-only `allow_symlinked_codex_home` user setting. When enabled in the execution host's `$CODEX_HOME/config.toml`, writable roots at or beneath that home may traverse symlinks.
- Keep the exception disabled by default and prevent project config, command-line overrides, and ignored user config from enabling it. Other writable roots remain subject to symlink checks.
- Propagate the resolved setting through local, interactive, and exec-server sandbox paths, including `CODEX_HOME` aliases.
- Explain the opt-out in symlink rejection errors, including that it trusts targets outside `CODEX_HOME` and targets that change between commands.
## Testing
- Add macOS coverage for shell commands, patches, filesystem helpers, process execution, and interactive startup with enabled, disabled, aliased, and out-of-scope homes.
GitOrigin-RevId: 99fcdf611200c9e1b7713cf06f7fdea5bfa7f089
## What changed
- Add the experimental `worktrees` feature and a shared `--worktree` flag for new and forked `codex exec` sessions.
- Create each enabled session in a managed Git worktree, use that checkout as the session working directory, and bind the checkout to the new thread.
- Share the configured worktree pool with Desktop while leaving automatic cleanup disabled for CLI allocations.
- Reject unsupported commands, remote execution, ignored user configuration, ephemeral sessions, and use without the feature enabled before allocating a worktree.
## Testing
- Cover flag placement and inheritance, supported and rejected command combinations, worktree allocation and thread ownership, configuration gating, and compatibility with existing worktree-backed sessions.
GitOrigin-RevId: 011ff4639b09e8992c50d7b823df23e71798670e
## What changed
- Pass the selected executor's `PathUri` through user command approval requests instead of converting the working directory to a host-native path.
- Make native-path permission helpers explicitly local and require executor-aware permission transforms to receive a `FileSystemSandboxPolicyContext`.
- Cover approved remote commands to verify that the approval request reports the selected remote working directory and execution resumes after approval.
GitOrigin-RevId: 0aa3042f2d7594af6c7d0abf31d7f99cf67d5556
## What changed
- Add the creation-time `originator` to app-server thread responses and `thread/started` notifications.
- Persist originators in thread metadata and preserve the first recorded value across list, read, resume, rollout, and SQLite paths.
- Add an `originators` allowlist to `thread/list` for hosted backends. The local app-server accepts omitted or empty values but rejects nonempty filters.
## Testing
- Cover originator persistence across server restarts and list, read, and resume requests.
- Verify local `thread/list` handling for nonempty, omitted, null, and empty originator filters.
- Heap-allocate large TUI dispatcher futures in affected tests to keep them within the Windows test-thread stack.
GitOrigin-RevId: 73ad6e61b8fdd2d93a22d1f971723a19ec7be3fc
## Why
Directly deserializing the flattened `RolloutLine` envelope can reject nested
decimal values, preventing affected paginated sessions from resuming.
## What changed
- Add canonical string, byte, and reverse-scanner helpers that decode rollout
records through `serde_json::Value` before decoding the flattened item.
- Route rollout readers across session discovery, history, migration, search,
thread storage, and transcript previews through those helpers.
- Remove `Deserialize` from `RolloutLine` so new readers cannot bypass the
canonical persistence decoder.
## Testing
Add coverage that resumes a paginated rollout after a token-count record with
a decimal rate-limit value and verifies that ordinal sequencing continues.

## What changed
- Make `local_thread_store_compression` compress cold rollout files across shared and forked histories without a separate compression mode.
- Retire `local_thread_store_shared_compression` while continuing to accept it in strict configuration without changing compression behavior.
- Read rollout files through the compressed-rollout reader when `codex exec resume` determines the latest turn's working directory.
## Testing
- Cover compression and restoration of an archived fork chain.
- Cover cwd-based resume selection when only the compressed rollout remains.
- Cover the removed compatibility key in strict configuration.

## What changed
- Emit turn-scoped authentication recovery started and completed events when a model provider refreshes expired credentials.
- Add stable `modelProvider/authRecoveryStarted` and `modelProvider/authRecoveryCompleted` app-server notifications with the thread, turn, provider, and user-facing message.
- Show recovery progress in the TUI and `codex exec`, including Amazon Bedrock session reauthentication.
## Testing
- Cover provider recovery success and failure events, app-server routing, client rendering, and Amazon Bedrock credential refresh.

## What changed
- Add an optional `toolOutput` to `turn/start` for starting or steering a turn with a named function-call output instead of user input.
- Emit standalone outputs as `functionCallOutput` thread items, persist them in durable history, and include them in resumed threads.
- Validate that tool outputs have a name, are not combined with nonempty `input`, satisfy the text-size limit, and use supported image URLs.
## Testing
- Cover standalone tool-output notifications, model input, and resumed history in both legacy and paginated history modes.
- Cover the text-size limit for structured tool output.

## What changed
- Add the experimental `turn/start.cyberAccessProgram` option with `standard`,
`daybreakBlue`, and `daybreakRed` values.
- Forward the selection as `access_programs.cyber` on Responses, WebSocket,
and remote-compaction requests made with ChatGPT authentication, while
omitting it for API-key and custom-provider requests.
- Preserve the per-turn selection across recovery, compaction, and child-agent
turns without making it a persistent thread setting.
## Testing
- Cover app-server forwarding, authentication boundaries, WebSocket reuse,
turn recovery, compaction, and child-agent inheritance.

## What changed
- Add an optional `turnTrigger` field to app-server `turn/start` requests and
expose it in the generated protocol schemas.
- Propagate non-empty trigger values to Responses request metadata as the
reserved `turn_trigger` field, while preserving the original value when a
request steers an active turn.
- Classify turns started by queue dispatch, goal continuation, retry recovery,
and realtime handoff.
## Testing
- Cover HTTP and WebSocket metadata forwarding, steering behavior, reserved
metadata handling, and the built-in trigger classifications.

## What changed
- Add `serviceTierForTurn` to `turn/start` so a newly started turn can override the service tier without changing the thread's saved tier.
- Treat `"default"` as standard speed and omitted or `null` values as inheriting the thread tier.
- Keep `serviceTier` authoritative for subsequent turns when both fields are supplied, and ignore the turn-scoped override when steering an active turn.
## Testing
- Extend the app-server turn-start test to verify both the one-turn `"default"` override and inheritance on the following turn.

## What changed
- Add a global `codex exec --thread-source <SOURCE>` option and propagate it to newly created and forked threads.
- Default the source to `user` when the option is omitted.
- Expose the classification as `threadSource` in the TypeScript SDK. It applies when a thread is first created and does not override the source when resuming an existing thread.
## Testing
- Cover CLI parsing and persisted metadata for new, resumed, and forked threads.
- Verify that the TypeScript SDK forwards `threadSource` only for new threads.

## Why
Cold resumes and forks could lose the thread's active permission profile and
fall back to the current configured default.
## What changed
- Restore the latest persisted approval policy, approvals reviewer, and active
permission-profile ID when resuming or forking a thread.
- Re-resolve persisted profile IDs through current configuration and
requirements. Missing or invalid profiles fall back to the configured
default, while threads without a persisted profile continue to use current
configuration.
- Keep explicit permission and approval overrides ahead of persisted settings.
## Testing
Added coverage for legacy and paginated histories, settings updates, explicit
overrides, removed or changed profiles, requirement fallbacks, and forks.

## What changed
- Request paginated history when `codex exec` starts a persistent thread.
- Keep ephemeral threads unchanged and retry with legacy history when the configured thread store does not support pagination.
- Exercise paginated resume and fork persistence, including resumed history and fork ancestry without copying the source transcript.
## Testing
- Extend unit coverage for persistent and ephemeral thread start parameters.
- Add an integration test for the legacy-history fallback.
