## Why
Permission summaries must preserve executor paths without interpreting them in the host's filesystem namespace.
## What changed
Accept `PathUri` values and summarize permission profiles directly instead of converting them to a legacy sandbox policy. Render additional workspace roots using their inferred native path convention, and update the exec and TUI callers.
Keep workspace subpath writes and writes outside the working directory classified as `custom permissions` when the working directory itself is not writable.
## Testing
Add coverage for POSIX, Windows drive, and UNC workspace paths, including encoded spaces and case-distinct roots, plus opaque workspace subpath writes.
GitOrigin-RevId: ff2c456e2a720e7216f13e0241b3a935cc925d00
## What changed
Add `codex-mermaid`, a standalone crate that renders supported subsets of flowchart, sequence, state, class, and ER diagrams as Unicode text. Expose `render` for plain text and `render_spans` for semantic node, edge, and text spans that callers can style.
Enforce source, diagram, canvas, and display-width limits. Return errors for unsupported input or exceeded limits without producing partial diagrams, leaving source fallback to callers. Include documentation and a stdin rendering example.
## Testing
Add snapshots for each diagram family, checks for relationship endpoints, Unicode labels, semantic spans, truncated input, and size limits, plus edge reconstruction for all 512 directed three-node graphs in all four layout directions.
GitOrigin-RevId: 5b4e65d9152abce5d833e4e6b12113a5a21f700e
## What changed
- Add an optional `WorkspaceRoutingResolver` to `AuthManager` and pass session configuration into routing lookups. Callers without a resolver retain existing routing behavior.
- Apply resolved backend origins and account routing overrides to eligible ChatGPT Responses HTTP requests and WebSocket handshakes. Preserve endpoint paths, validate routing values, and reject HTTP redirects for routed requests, including `NO_CONSTRAINT` routes.
- Key cached WebSocket connections by destination, routing header, and auth revision. Rebuild request setup after credential refreshes and reject account changes during setup or routing discovery.
- Serialize routing lookups per session and retain whether the session has previously been routed.
## Testing
Add tests for path preservation, provider exclusions, concurrent routing lookups, unavailable resolvers, workspace mismatches, redirect rejection, and credential refresh or account changes during request setup.
GitOrigin-RevId: 2b6609019e84a315745c94858955f3f16426fe7f
## Why
Packaged uninstall could leave sandbox user profiles and desktop-created data behind. Cleanup also needs to handle a service stop before package removal completes without deleting data belonging to an update or reinstall.
## What changed
- Delete sandbox profiles before their accounts, preserving accounts for retry when profile deletion fails. Defer retained runtime accounts and the sandbox group until runtime registrations are removed and profiles unload.
- Allow cleanup while the exact retiring package is still registered, while preserving desktop data when a successor package is present.
- Remove desktop-created Codex homes during registered runtime cleanup, preserve existing CLI data, and prune empty home and cache directories. Keep directory pins through retries and avoid privileged traversal after releasing the home.
- Retry cleanup up to five attempts after a service stop, while retaining shutdown cancellation behavior.
- Report cleanup outcomes in the Windows Event Log and emit final completion after registered runtime cleanup finishes. Remove the empty installation registry parent.
## Testing
Add Windows tests for profile deletion retry and account preservation, service-stop retries versus system shutdown, and PowerShell finalizer parsing and native binding compilation. Extend retained-token coverage to check account SID matching.
GitOrigin-RevId: 1aefa969e6aff9bb8e77e2c9fe9ee772230fc4fb
## What changed
- Track the Windows sandbox implementation separately from its legacy setup level.
- Select dedicated proxy listeners for `WindowsMxc` on Windows across sessions, app-server command execution, and the sandbox CLI.
- Rebuild the session proxy when routing changes, retaining its network policy decider.
- Add a sandbox CLI execution path through the MXC sandbox transform when `WindowsMxc` is selected.
## Testing
Extend configuration assertions for the selected sandbox type and the session refresh test to verify dedicated routing and policy decider retention on Windows.
GitOrigin-RevId: 2a22192636c542022ec81a378a16c1bb6867e145
## What changed
Add display models and adapters from typed backend responses for usage, credits, messages, plugins, and skills. Normalize reports into daily histories with grouping labels, units, and freshness timestamps.
Preserve missing values, signed credit adjustments, and full daily totals when grouping usage by task start. Account for unassigned message counts as `Other`, merge duplicate dates, and fill unreported days only for credit reports. Group models contributing less than 1% of relative usage into `Other`.
This adds the data preparation layer for dashboard integration; it is not yet connected to `/usage`.
## Testing
Add unit tests covering missing versus explicit zero values, signed credits, enterprise labels and freshness, usage grouping, duplicate-date message remainders, and unsupported message groupings.
GitOrigin-RevId: 931f46a9a6521b4cda2fc26051e7a305cbf6fa6c
## What changed
Move concrete reviewer settings into `guardian-v2` and replace `ReviewerConfigOverrides` with a `ReviewerConfig` callback stored in thread extension data. Apply the callback to each captured parent configuration before preparing context and checking session reuse.
Keep model selection, policy prompt construction, and live network state in the core adapter. Preserve the existing read-only reviewer settings and share `reviewer_permission_profile` with inherited environment configuration.
## Testing
Update existing Guardian configuration, session reuse, and prewarming tests to use the extension's actual configuration builder, including compiling the shared source in core's test host.
GitOrigin-RevId: dfa1dae9f8d4469f2e4f6e64ab842cc662970898
## What changed
- Record `auth_or_link` for Codex app calls with trusted connector authentication failure metadata, capturing it before result callbacks or model-facing rewrites. Propagate the classification to MCP tool-call and app-usage analytics.
- Record `approval` when a dispatched approval request is denied, times out, or aborts, covering both MCP elicitation and legacy user-input approvals.
## Testing
Add unit and turn-level coverage for authentication failures, metadata removal by callbacks, successful and rejected approvals, and closed approval response channels. Verify event counts, classification, and exclusion of sensitive test values and authentication URLs from analytics payloads.
GitOrigin-RevId: 493df2a2923f346a0f644f1f26ab8b6b9b8888e0
## What changed
- Use cancellation guards to tie reusable reviewers and temporary forks to their lifetimes, including when a review future is dropped. Replace cancelled reusable reviewers before reuse.
- Share `ReviewerTasks` between the pool and `ThreadManager`, and wait for tracked cleanup during pool shutdown. Remove the separate session shutdown protocol.
- Move denial cleanup from core task handling into Guardian's turn start, stop, and abort hooks. Expose `install_reviewer` to register both thread and turn lifecycle contributors together.
## Testing
Add an integration test that exercises stale denial cleanup at turn start, completion, and interruption, including starting another turn after interruption.
GitOrigin-RevId: 85badb235309c1e1576547d1746f7ee9fc66d545
## What changed
Copy the source thread's current attachments when creating a non-ephemeral fork, including forks at an earlier turn. Copies receive new attachment IDs and creation timestamps while preserving resource identities and payloads. Attachment membership can then change independently on either thread; referenced resources are not copied.
Await the atomic copy before publishing the fork. If copying fails, log the error and allow the conversation fork to succeed without attachments. Resuming a fork does not copy attachments again.
Document that clients should use `forkedFromId` on `thread/started` and fetch the fork's attachments with `thread/attachment/list`; copying does not emit per-attachment updates.
## Testing
Add coverage for atomic rollback, independent attachment membership, inheritance across history cutoffs, successful conversation forks after copy failures, and resuming without restoring removed attachments.
GitOrigin-RevId: 939d2c6a3073ccfcd922380c6beda45d3deac606
## Why
Daemon lifecycle commands previously required a standalone managed installation. A complete CLI package can supply the daemon executable and helpers without requiring a separate installer run.
## What changed
- Let `codex app-server daemon start`, `restart`, and `bootstrap` copy the invoking package into `CODEX_HOME/packages/app-server-daemon` when no daemon installation exists.
- Validate the package's platform, required helpers, executable identity, and copied contents before selecting the staged release.
- Preserve existing dedicated and legacy daemon selections, reject broken selections instead of replacing them, and leave the CLI package and selection unchanged.
- Preserve standalone release pins and latest-channel eligibility, and select dedicated releases using Unix symlinks or Windows junctions.
## Testing
Add package preparation tests for complete copies, incomplete packages, broken selections, legacy preservation, and update-channel handling. Add Windows junction creation and retargeting coverage, plus CLI integration tests that launch the copied package through `start`, `restart`, and `bootstrap`.
GitOrigin-RevId: abd2f4f82eae0885434ea30603c2c1c0ca760bef
## What changed
Replace `AttachmentStore::persist` with `upload` and `resolve`. Uploads return inline bytes or a file ID; resolution returns optional file metadata and a download URL only when a minimum URL lifetime is requested. Add image dimensions, digest, size, MIME type, and categorized errors to the API.
Make `InlineAttachmentStore` return the original bytes and report `NotFound` when resolving file IDs. Redact attachment bytes and file URLs in debug output.
Pass the configured image store from the thread manager into sessions and inherit it in delegated sessions. Allow `TestCodexBuilder` to accept a custom image store.
## Testing
Update unit coverage for preserving PNG and JPEG bytes, redacting bytes and URLs in debug output, and rejecting file resolution in the inline store.
GitOrigin-RevId: f313e0048925998d84394c7e5a278e0d39d86a45
## Why
Guardian reviews must stop when their parent shuts down or their history is reset. Shutdown must also finish reviewer cleanup before closing the parent's persistent history, including when a review is waiting to retry after a rate limit.
## What changed
- Let the Guardian extension own reviewer startup, prewarming, and shutdown through `ThreadManager`, tracking and joining outstanding work during teardown.
- Cancel reviews on history reset or parent shutdown and reject decisions returned after cancellation, including cached extension decisions.
- Keep background prewarm previews from overwriting the active turn's model metadata.
## Testing
Extend regression coverage to verify reviewer cleanup after parent shutdown, prompt shutdown during a 60-second Guardian retry with the network request denied, and preservation of active model review requirements during prewarming.
GitOrigin-RevId: 05efc369b9a1642a10365eac8a09da77f3f6e28c
## What changed
- Report `windows_mxc` from native MXC availability on Windows.
- Allow MXC TTY launches and managed networking, using dedicated proxy listeners without requiring a shared-ingress restricting SID.
- Reject MXC custom `argv0` and private-desktop launches, and continue failing closed when native MXC is unavailable.
## Testing
Extend the Windows remote sandbox process-write test to cover MXC with both pipes and ConPTY. Retain coverage for rejecting MXC requests when native support is unavailable.
GitOrigin-RevId: 80c5f319b9066d06b26f0a7eb7119a109e6ebef7
Add `base64` and `serde_json` as workspace dependencies of
`codex-windows-sandbox-service` and update `Cargo.lock`. Temporarily exclude
both dependencies from `cargo-shear` checks until they are used.
GitOrigin-RevId: f77a0ba13cfa9ba2315dcf00a80163afff32d0b4
## Why
Inline delegates have no entry in the thread registry, so reviewer creation cannot depend on looking up the parent or waiting for its thread-ready notification.
## What changed
- Capture parent identity, authentication, shared agent control, originator, and inherited instructions in `StartThreadOptions` so `ThreadManager` can start a child without a registered parent.
- Route Guardian reviewer creation through this path, remove the standalone fallback and readiness gate, and require a Guardian extension host.
- Install explicit reviewer hosts in unit tests and the Guardian reviewer extension in the integration test harness, using `ExtensionRegistry::to_builder()` to preserve existing contributors.
## Testing
Extend the thread-manager regression test to remove the parent from the registry before starting a child, then verify inherited lineage, originator, session identity, and authentication, and exclusion from the public thread list.
GitOrigin-RevId: 468ded6fdce7520cb39d55c1a884dcfa5aaea2d9
## What changed
Add an `instructions.load` tracing span with `provider = "global"` around loading user instructions from the Codex home directory. Skip recording function arguments and add the `tracing` dependency to `codex-home`.
GitOrigin-RevId: 1b11e4b18f7a0dbee742a092aba580a184dc5fbf
## What changed
- Update `rustls` from 0.23.36 to 0.23.45 and `rustls-webpki` from 0.103.13 to 0.103.15.
- Update `aws-lc-rs` from 1.16.2 to 1.18.1 and `aws-lc-sys` from 0.39.0 to 0.45.0, including its new `pkg-config` dependency.
- Refresh the corresponding dependency metadata in `MODULE.bazel.lock`.
GitOrigin-RevId: 7b37b3cea5485c0b5bd11d229b2949aec399afd9
## What changed
Add `ConversationState` and `ConversationCheckpoint` to `codex-guardian-reviewer` and use them in core review sessions to track transcript cursors, completed review counts, and committed snapshots. Keep history and admitted evidence host-owned.
Preserve the separation between live review progress and committed checkpoints so forks inherit the history, cursor, and review count from the last committed snapshot.
## Testing
Add a unit test verifying that forks retain committed history and progress after an uncommitted review, then advance when the next snapshot is committed.
GitOrigin-RevId: 9f92410b11beec6b8f413c4c922fabba65852399
## Why
Desktop uninstall cleanup needs an installation owner even when the user has not signed in or configured the Windows sandbox. Recording ownership only during provisioning leaves those installations unregistered.
## What changed
- Add an authenticated installation registration request and attempt it during Windows desktop stdio initialization, with a five-second timeout before the initialization response.
- Persist ownership independently of provisioning, preserve existing desktop ownership, and prevent another user or home from replacing the registered owner.
- Validate write authority and retain directory handles and guards to protect the registered home against junction conversion through privileged cleanup.
- Preserve existing CLI homes during desktop uninstall while removing their `CodexSandboxUsers` ACL entries. Report ACL revocation errors and avoid propagating unchanged ACLs.
- Grant the owner `WRITE_DAC` on `.sandbox-bin` and allow elevated-helper fallback when older permissions need repair or the service cannot establish an uninstall watcher.
## Testing
Add tests for installation registration without sandbox settings and for preserving a child's null DACL when revoking an absent SID from its parent.
GitOrigin-RevId: fb48923e9d76758d1bf5b50c7305aa60f91629db
## What changed
- Move the setup helper implementation and its existing tests into `codex-windows-sandbox`, with the binary delegating to `setup_helper_main`.
- Expose installation record types and storage operations from the library, preserving the registry key, size limit, and serialization format. Reuse them in the service and remove its direct `serde` dependencies.
- Extract service provisioning from IPC handling into a dedicated module, preserving authentication and machine-policy checks before provisioning and retaining directory handles through helper execution.
GitOrigin-RevId: dd1ea015aff901d5dfe39b395de1971ee0f2d33f
## What changed
- Use one renderer for captured requests, raw request bodies, and input items. Show only appended items when inputs extend the previous request and settings match; start a new snapshot window otherwise and explain the boundary.
- Add optional request settings and tool inventory deltas. Normalize volatile values with stable labels, preserve multiline content, and fingerprint omitted content so changes remain visible.
- Migrate existing context snapshots and expand compaction snapshots to include request history.
## Testing
Add focused tests for window boundaries, cache key changes, tool deltas, shared item rendering, stable normalization, and fingerprints. Assert that the follow-up request after pre-turn compaction includes the working directory override.
GitOrigin-RevId: 6445b014081208ea432b1f3e2ac835c5e4955cb0
## Why
Windows release packages need the voice helper and native audio libraries. Realtime TLS connections on fresh Windows installations also need platform certificate validation so Windows can retrieve missing trusted roots on demand.
## What changed
- Build and sign the voice helper and audio DLLs for Windows x64 and ARM64, bundle a pinned Microsoft CRT DLL, and verify signatures and runtime receipts before packaging.
- Add verified, pinned Cygwin and native build tools plus MSVC linker, compiler, and path handling fixes for the Windows Bazel builds.
- Include voice resources in primary release archives and WinGet packages. Preserve WinGet executable names, update manifest hashes, and recognize the package root through matching entrypoint metadata. Keep Python runtime wheels voice-free to preserve their existing Windows support floor.
- Use Windows platform TLS validation for realtime WebSockets when no custom CA bundle is configured, preserving custom CA behavior.
## Testing
Add coverage for build-input integrity and unsafe paths, signed Windows runtime assembly, WinGet file and hash preservation, package discovery, and TLS trust selection, untrusted certificate rejection, and hostname validation.
GitOrigin-RevId: 423da35872fa5549d69fd4ca97d922bb49599386
## What changed
Add `create_command_args()` to encode argv, permissions, policy cwd, and optional managed network context through the existing bounded environment transport.
For managed networking, generate a policy that allows IPv4 and IPv6 loopback while denying direct non-loopback egress and general inbound access. Require nonempty, nonzero proxy ports and reject `allow_local_binding=false` at both launcher and policy boundaries because native host-loopback access is bidirectional.
Document the MXC launch contract, platform requirements, and limitations.
## Testing
Add portable tests covering managed network transport and policy translation, plus rejection of missing proxy ports, zero ports, and unsupported local-binding restrictions at both boundaries.
GitOrigin-RevId: 8d31b98f94a2ba3769369aa50de8e53dc143bac4
## What changed
- Bump `quinn-proto` from `0.11.14` to `0.11.15` in the Cargo and Bazel lockfiles.
- Allow `hyperium/h3` as a Git source in `codex-rs/deny.toml` for the pinned revision needed by `CONNECT` request handling until released.
GitOrigin-RevId: 1e977e28d9e57acd8eac6a49a5e15fe04602c38d
## Why
Audio queue saturation and processing delays could terminate voice sessions. Muted sessions also need outgoing audio to keep the peer alive.
## What changed
- Drop stale or excess incoming, capture, render-reference, and playback audio so fresh audio can resume. Reset affected processing state while preserving queue bounds and mute generations.
- Send paced, generated Opus silence while muted, without using device or processing buffers.
- Add fixed helper exit stages and session failure categories to default TUI logs without logging raw native errors, SDP, or device error text. Preserve observed helper exit status for shutdown.
## Testing
Extend tests to cover decoded mute silence and RTP sequence continuity, recovery after stale audio and queue saturation, and shutdown after observing helper output closure. Verify the helper's exit stage when the parent pipe closes during blocked startup.
GitOrigin-RevId: 17d580a72acd4423fb0b4f5107d9b541b964d069
## Why
The TUI should respect the host's accessibility preference even when `tui.animations` is enabled.
## What changed
- Read the system motion preference once at launch on macOS, Windows, and Linux. Changes to that preference require restarting the TUI.
- Suppress animations when reduced motion is requested without changing saved configuration. Preserve configured behavior when detection is unavailable, and limit the Linux portal query to 250 ms.
- Use the effective animation setting for voice controls and transcripts, and honor system reduced motion in the startup composer.
## Testing
Add tests for animation preference resolution and preservation of saved settings, plus composer snapshots without sparkles at widths of 40 and 80 columns.
GitOrigin-RevId: 3ea4e721ae23220a040a06123a27286a8c8f1c7c
## Why
Sandbox policies can exceed Windows command-line limits. Provide an environment transport for these larger MXC launch requests.
## What changed
- Make `MxcCommand` serializable and add JSON encoding and decoding through `CODEX_MXC_LAUNCH_*` environment variables.
- Split payloads into UTF-8-safe chunks of at most 4,096 bytes, with a 1,000,000-byte payload limit and at most 256 chunks.
- Reject malformed or duplicate transport entries and remove all transport variables during decoding, including on failure. Preserve unrelated environment variables.
## Testing
Add tests for large Unicode and escaped-argument round trips, stale variable removal, malformed transport rejection and cleanup, and oversized payload rejection without modifying the environment.
GitOrigin-RevId: 0e5ae2535ef313985a95eb8a5fd4884974dfb1eb
## What changed
- Move assessment event construction, metrics, and analytics tracking into `codex-guardian-reviewer` through `ReviewReport`.
- Store denial accounting in thread extension data through `ReviewDenials`, with core retaining turn interruption and lifecycle cleanup.
- Move failed-review record selection and bounded serialization into the extension, with core supplying captured review context.
## Testing
Add coverage that denial accounting clears on turn completion and interruption. Move the oversized-record test into the extension and exercise the new API.
GitOrigin-RevId: 6e5b3d9d4128b356f99b1d0e74a68111e40261ab
## What changed
- Move reviewer configuration overrides, turn request construction, and deadline, cancellation, and completion handling into `codex-guardian-reviewer`.
- Adapt core sessions through `ReviewerRuntime`, keeping context construction, managed constraints, and live network rules in core.
- Make `GuardianReviewSession` crate-private and remove direct reviewer pool initialization and the reviewer dependency from `guardian-v2`.
## Testing
Update the turn-draining test to exercise `wait_for_guardian_review`, checking that prior-turn completion events are ignored and the session remains reusable after draining the current turn.
GitOrigin-RevId: fdf2b335b88b3f405d2370298ee68932808e1186
## Why
Stdio shutdown can hang on open pipes or blocked I/O, and Unix `SIGTERM` needs to run connection cleanup so owned commands terminate and session-end hooks execute.
## What changed
- Handle `SIGTERM` on a dedicated signal thread and close the stdio connection through the existing cleanup path.
- Move blocking stdin and stdout operations to dedicated threads so they do not hold the Tokio runtime open. Cancel message forwarding on `SIGTERM` to release blocked producers.
- When shutdown signal handling is enabled on Unix, start a shared 45-second watchdog on EOF or `SIGTERM`. Preserve the first deadline and exit with status `1` if cleanup or runtime teardown stalls, even when logging is blocked.
## Testing
Add Unix integration coverage for shutdown with open pipes, blocked stdout, blocked stderr, and a stalled filesystem write. Verify command and child-process termination, preserve the EOF deadline when `SIGTERM` follows, and extend session-end hook coverage to `SIGTERM`.
GitOrigin-RevId: 43a80b8277eb50519cdc293eb3b5dc2cad00b3aa
## Why
MXC volume-root grants are nonrecursive, and filesystem deny globs were rejected before launch.
## What changed
- Expand volume-root grants to include existing immediate children, preserving read-only carveouts and denies. Children created directly under a volume root after policy construction are not granted access.
- Normalize filesystem object aliases before and after expansion so generated grants preserve tighter access restrictions.
- Skip unavailable volumes and uninspectable generated children.
- Resolve deny globs into concrete file and directory paths using the Windows sandbox resolver.
## Testing
Add regression tests for read-only children and aliases, normalized root access, uninspectable children, and deny glob expansion alongside explicit denies.
GitOrigin-RevId: 3242e9a30d16581d6fe5b7b6e39e0e0f71ca6ef4
## What changed
Probe the default Windows system config namespace at session start and record `codex.windows_system_config.namespace_squatting_probe` once per process when metrics are available.
When `config.toml` or `requirements.toml` exists, check the containing directories for expected ownership and broad standard-user mutation allow ACEs, including permissions inherited by child files. Report coarse results for missing files, expected directories, unexpected types or owners, mutation permissions, and check errors.
The probe is observational: it does not change configuration loading or enforce a trust decision.
GitOrigin-RevId: e1c79dca5548e16e83c7b84b44ab0de4e2643d0d
## Why
Loaded threads, including idle threads whose rollout files are still deferred, need to survive a managed daemon restart. Shutdown must also remain forceable when rollout I/O is blocked.
## What changed
- Add a hidden `--managed-daemon` option for app-server Unix socket transports. After active turns and admitted requests drain, save loaded persistent root threads before exiting.
- Skip ephemeral threads, non-root agent threads, and threads pending unload. Log persistence failures and continue saving other threads.
- Apply shutdown admission checks to thread and turn settings updates, thread deletion, and archiving.
- Keep force signals and daemon shutdown requests responsive during persistence. Return `AppServerExit::Forced` so executables can exit without waiting for runtime teardown.
## Testing
Add integration coverage for resuming active and idle threads after restart, forcing shutdown during active work, and forcing shutdown with a blocked rollout writer. Extend shutdown rejection coverage to deletion and settings updates.
GitOrigin-RevId: 4344e97d39f9f80c5d84c41c17300fd6aa99b4cc
## What changed
Move the synchronous review loop, outcome mapping, deadline helpers, and session pool into `codex-guardian-reviewer`. Core supplies adapters for evidence capture, authorization checks, session creation, and event publication through the new host interfaces.
Have `guardian-v2` initialize the reviewer pool and host separately, with the pool managing prewarming, session reuse, concurrent forks, invalidation, and shutdown.
## Testing
Extend the app-server reviewer lifecycle test to cover interrupted concurrent reviews as well as completed reviews, including resuming a reviewer after parent shutdown. Adapt core reviewer tests to use the pool and factory interfaces.
GitOrigin-RevId: 2d69bd20c169b20534764b98cbdb63f38564a530
## What changed
- Let higher-priority providers in `features.network_proxy.credentials` displace lower-priority providers with overlapping `env` sources, including in profiles. Preserve inherited settings when providers swap sources, and compare environment names case-insensitively on Windows.
- Preserve provider definitions across ordered batch remaps and persist displaced-provider removals without overwriting unrelated sibling updates.
- Validate remapped providers using the credential broker's compilation rules before persisting writes, while allowing incomplete drafts and explicit deletions.
- Omit displaced providers from config origins and report writes overridden by another provider's source ownership.
- Build trusted credential-broker configuration before merging managed layers for project discovery, preserving remapped providers' environment protections.
## Testing
Add unit and config RPC regression tests for source precedence, source swaps, ordered edits, concurrent sibling updates, atomic rejection of invalid remaps, persistence, and override reporting. Add a macOS managed-config regression test for remapped provider bindings during project discovery.
GitOrigin-RevId: b7d402727acf4e5b0f25946db1cf18811f5e2679
## What changed
Move assessment parsing and schema, model selection, review outcomes, retry handling, and rejection circuit breakers into `codex-guardian-reviewer`. Update core to use the extracted APIs while retaining session execution and decision enforcement in the host.
## Testing
Move existing assessment, circuit breaker, and retry tests into the new crate, including coverage for transient errors, cancellation, and deadlines.
GitOrigin-RevId: 96ec9989a0066acb012bf3bec0b9f7d8bf11a4ef
## Why
Diagnostic attachment reads assume the queued file path still exists and contains plain bytes. Compressed rollouts can therefore be omitted when only the logical `.jsonl` path is available, or attached as compressed data when a `.jsonl.zst` path is supplied.
## What changed
- Read rollout attachments through a bounded decoder that resolves plain or compressed representations without materializing a durable JSONL file.
- Use canonical `.jsonl` filenames for attachments and app-server report metadata, while preserving filename overrides.
- Apply size limits to decoded bytes and preserve JSONL prefix truncation.
## Testing
Add regression tests for compressed attachments, representation changes after queuing, plain-sibling preference, filename overrides, decoded size limits, truncation, nonregular files, and unrelated `.zst` attachments.
GitOrigin-RevId: b30f7dd08a741b0c99283460a1ce8933d2920ddf
## Why
Credential brokerage must retain trusted destination hints even when shell environment policy hides them from child processes. Snapshot replay also needs to preserve credential aliases when tokens are short or captured dummy values change.
## What changed
- Add `features.network_proxy.credentials` and preserve provider settings when toggling the proxy. Prevent project configuration from overriding providers or their credential and destination environment variables.
- Use provider metadata throughout snapshot capture and replay, and pass hidden destination context to the broker without exposing it in the child environment.
- Rewrite aliases containing short credentials or previously captured dummies, respecting environment filters and explicit overrides.
- Preserve case-distinct `shell_environment_policy.set` keys so Windows credential ambiguity checks survive configuration merging and permission profile changes.
- Restore independent MITM settings when credential brokerage is disabled.
## Testing
Add regression coverage for custom providers, hidden destination hints, Bash and Zsh alias replay, configuration edits and merging, Windows ambiguity handling, and credential protection during approved execution.
GitOrigin-RevId: b2bd935d2d8555be56baf8feb1a8e5b3a0c666bc
## What changed
- Discover configured provider credentials in child environment values even when canonical credential variables are absent. Match complete tokens while preserving regex word boundaries and avoiding ambiguous or overlapping provider matches.
- Replace and restore credentials by their original spans, preserving adjacent tokens and generated dummy aliases across destination rebinding. Reject dummy values that embed another provider's credentials.
- Extend text virtualization and provider source checks to configured credentials, including short credentials with distinctive prefixes, while preserving operational paths.
- Expose trusted provider metadata and active bindings through `CredentialBrokerEnvironment`, and remove marked configured credential variables when stripping the managed proxy environment.
## Testing
Add regression tests for alias discovery, regex boundaries and alternatives, overlapping and adjacent credentials, destination rebinding, dummy restoration, disallowed credential sources, and operational path preservation.
GitOrigin-RevId: dd85c595ce9550fbfdb07ef296a23e458ca165dd
## What changed
- Add `credential_providers` configuration for environment variables, credential patterns, static or environment-derived URL prefixes, and bearer, token, Basic, or custom header authentication.
- Generate matching dummy credentials and restrict replacement to authorized schemes, hosts, ports, and path prefixes. Scope credentials and destination history to each environment.
- Preserve real credentials for destinations that bypass the proxy with `allow_local_binding`, while providing snapshot redaction and alias matching.
- Validate provider definitions and preserve unchanged providers across configuration reloads.
## Testing
Add coverage for dummy generation, authentication translation, URL restrictions, environment isolation, configuration reloads, and credential restoration for local proxy bypass.

## What changed
Support `model_providers.amazon-bedrock.aws.credential_export` with `command`, `args`, and `timeout_ms` to supply SigV4 signing credentials from a command's JSON output. Accept both flat credential-process output and nested STS `Credentials` objects.
Cache credentials in memory, refresh before expiration, and share exports across sessions with matching AWS configuration. On recoverable authentication failures, run the optional `aws.auth_refresh` command before exporting fresh credentials, coalescing concurrent recovery attempts.
Bound command execution time and output size, and keep credential values out of errors. Reject combining `aws.credential_export` with `aws.profile`. Bedrock setup and login reject changes while an exporter is configured, preserving configuration and saved credentials.
## Testing
Add coverage for output formats, expiration, credential precedence, caching, concurrent recovery, command failures, and secret redaction. Integration tests verify request signing with rotated credentials, bounded recovery attempts, and setup/login rejection across configuration layers.

## Why
Switching providers or authentication could reuse a previous identity's model catalog, including its default service tier. An in-flight refresh could also overwrite a newer account's catalog after cache storage completed.
## What changed
- Require a matching provider and auth identity for disk and in-memory catalog reuse. Treat legacy entries without an identity as cache misses and fall back to bundled metadata when the in-memory identity no longer matches.
- Recheck identity after fetching and storing a catalog before publishing it.
- Renew cache freshness only when the client version, identity, and ETag match the stored entry.
- Update cache fixtures to include the configured provider and auth identity.
## Testing
Add regression coverage for provider and auth switches, credential rotation, legacy and mismatched cache entries, conditional TTL renewal, and an account switch during cache storage. Verify that API-key requests do not inherit a ChatGPT catalog's default `service_tier`, while explicit tier selection still works.

## What changed
Add a SHA-256 identity derived from provider routing, headers, and authentication scope. Return it with each model catalog response and persist it in `ModelsCacheEntry`. ChatGPT credentials with stable account and user metadata retain the same identity across token refreshes; opaque API credentials contribute to the digest.
## Testing
Add identity tests covering account, user, email, plan, auth mode, provider routing, headers, and API credential changes, plus stability across ChatGPT token refreshes. Update cache tests to include the persisted identity.

## Why
A descendant outside an MCP server's process group can keep stderr open after the server exits, leaving the reader task and its file descriptor alive.
## What changed
Signal the local stderr reader during explicit shutdown and when the process handle is dropped. Allow up to 250 ms to drain queued diagnostics before closing the reader, even if stderr never reaches EOF.
## Testing
Add a Unix regression test covering explicit shutdown and client drop with a descendant that keeps stderr open. Verify that file descriptor counts return to baseline while the descendant remains alive and that queued diagnostics are logged.

## What changed
Add `policy::build_request` to `codex-rs/mxc-sandbox` to translate `MxcCommand` permissions into native MXC execution requests. Preserve filesystem denies, read-only carveouts, and protected metadata paths, and resolve overlapping grants using canonical path identities.
Map network permissions to ingress, egress, and loopback policies; quote arguments for Windows process creation; and disable DACL mutation fallback. Reject unsupported symbolic roots and deny globs, empty commands, relative working directories, and non-Unicode request paths.
## Testing
Enable unit tests and add coverage for filesystem grants and carveouts, disabled DACL mutation, deny-glob rejection, relative working directories, and non-Unicode paths.

## Why
Enterprise sign-in needs to keep browser completion separate from credential storage so callers can recheck the active account and configuration before saving a grant. Logout must also prevent an earlier sign-in from restoring credentials, including from another process sharing `CODEX_HOME`.
## What changed
- Add enterprise login APIs in `rmcp-client` that return an authorization URL and stage validated credentials for an explicit `commit_if` call. Store grants only in the keyring after rechecking caller authority under the credential lock.
- Require a registered client ID, published metadata matching the configured issuer, HTTP loopback callbacks, a refresh token, and a valid OIDC identity assertion. Request `openid` and `offline_access` with `prompt=consent`, and omit MCP resource indicators from authorization and code exchange.
- Persist a login generation under the credential lock so logout invalidates pending and staged sign-ins across processes, even when no grant is stored.
- Keep credentials and account identifiers out of enterprise error chains and logs, and avoid logging callback payloads when the receiver has closed.
## Testing
Add coverage for discovery validation, loopback callbacks, PKCE, staged keyring storage, cancellation, stale attempts, cross-process logout, and error/log privacy. Preserve ordinary MCP OAuth login without a refresh token, and adjust the terminal polling test deadline to include the minimum empty-poll wait.

## What changed
- Add `memories.version` with `v1` as the default and `v2` as an opt-in selection.
- Route memory generation, summaries, and retrieval tools through the selected version. Store `v2` artifacts in `memories_v2` and lazily create a separate SQLite database, keeping jobs and outputs isolated while sharing the thread catalog.
- Preserve the initial memory version across extension config updates so summaries and retrieval tools use the same namespace.
- Clear both versions on memory reset and remove thread memory from both stores on thread deletion. Recognize both artifact roots in shell usage telemetry.
## Testing
Add regression coverage for version defaults and validation, independent job claims and outputs, deletion and reset across versions, and shell usage classification for both memory roots.

## Why
The user-verification API previously returned an unsupported provider on macOS. Enable native verification using biometric-protected credentials.
## What changed
- Implement credential status, creation, reuse, deletion, and challenge signing with P-256 Secure Enclave keys in the Data Protection Keychain.
- Require biometric authentication through the key's access-control policy and use a fresh `LAContext` for each signature.
- Report Touch ID hardware support independently of enrollment and current readiness, and map native failures to structured verification errors.
- Serialize credential operations across processes with cancellable file-lock waits. Invalidate pending authentication on cancellation and wait for the signer to exit before releasing the lock.
## Testing
Add unit tests for lock contention and cancellation, authentication teardown and late-result rejection, native error classification, and validation of Secure Enclave key attributes.

## What changed
Represent host-verified tool metadata as `TrustedTool` in `codex-guardian-context` and collect it through an async-only context section. Route Guardian v2 sampling through that section while preserving separate developer-message delivery and the 512-token rendering budget. Omit tool metadata from debug output.
## Testing
Move the rendering-budget test into the shared crate, extend registry coverage for async-only collection and debug redaction, and narrow the scoped approval test to messages tagged `guardian.trusted_tool`.
