## Why
Package managers search parent directories for project configuration and hooks, which can influence Codex updates launched from a project directory.
## What changed
Run non-Windows update commands with `/` as their working directory.
## Testing
Add a regression test using a fake `pnpm` executable to verify that updates run outside the project even when `TMPDIR` points into it.
GitOrigin-RevId: a39b36872a62f2404aadd0614e1486d0755636fc
## Why
Registration can time out while resolving credentials, before any request is sent. Treating this as a transport timeout prevents a safe retry. Credential resolution timeouts can also incorrectly quarantine credentials when no OAuth refresh exchange has started.
## What changed
- Classify registration deadlines reached before the first send as `RequestNotSent`, allowing the existing registration retry loop to recover. Preserve transport timeout handling once a request has been sent.
- Track unsettled ChatGPT refreshes in `AuthManager` from the start of the OAuth exchange through credential persistence. Cancellation while waiting for the refresh guard or reading credentials does not mark them as unsettled.
- Have the executor auth provider withhold credentials with an unsettled refresh. Preserve uncertainty after a cancelled exchange even if a later refresh fails, while allowing replacement credentials and successfully completed refreshes.
## Testing
Add regression coverage for registration and connection deadlines across auth stages, retrying registration after an unsent credential timeout, recovery after slow replacement PAT metadata, and cancellation before and during OAuth refresh.
GitOrigin-RevId: f4d7ec2db7f79b8d313f1ee52dbd441094856669
## What changed
- Detect Rex from `TERM_PROGRAM=rex` or `TERM=xterm-rex` and report its name in terminal diagnostics.
- Enable Kitty graphics for pets in Rex.
- Use the detected terminal identity for Rex's label-only web links, extending that behavior to detection through `TERM`.
## Testing
Add Rex detection coverage for both environment variables and include Rex in the web-link rendering and Kitty graphics support tests.
GitOrigin-RevId: b237e8a6b3af50a55080573dc1e0badc2c139b42
## What changed
- Show draft attachment thumbnails in reference order in inline and fullscreen views on supported terminals with local workspaces. Display a `+N` count for attachments that do not fit, and preserve editable image references when previews are unavailable or space is limited.
- Refresh previews when attached files change, apply image orientation metadata, and clear frame graphics before terminal handoffs, screen switches, and shutdown.
- Finish CLI subcommand dispatch before polling interactive TUI events.
## Testing
Add a regression test and snapshot covering thumbnail order, overflow, resizing, attachment deletion, file replacement, and fallback behavior in both inline and fullscreen views.
GitOrigin-RevId: 1ea7c89e089cecc390e145c1790b6ede8bad8d5e
## Why
ChatGPT credentials can rotate while a remote executor is idle. Registry requests need to follow stored rotations without continuing after logout or switching the executor's identity. Concurrent refreshes must also avoid overwriting newer credentials.
## What changed
- Reload and validate ChatGPT credentials before registry requests, pinning the credential mode, account, user, and workspace policy. Reuse cached metadata for unchanged personal access tokens.
- Retry registration when temporary credential resolution failures prevent a request from being sent. Bound credential resolution and block reuse of a token generation whose refresh outcome is unknown.
- Restrict supported authentication modes before executor startup loads credentials or cloud configuration.
- Serialize persistent credential writes across cooperating processes and compare stored credentials before committing refreshed tokens.
- Replace `auth.json` atomically so overlapping readers see a complete document, preserving symlink targets and protecting file permissions, including Windows access controls.
## Testing
Add coverage for credential rotation, logout, identity changes, cancelled refresh callers, temporary metadata failures, registration retries, concurrent credential writes, and atomic file replacement.
GitOrigin-RevId: 6b210944bf8eba2f45bc27113f901d2c3cb06b48
## Why
The agent command center previously required a shared background server, preventing embedded sessions from opening it and rejecting `codex agents --no-daemon`.
## What changed
- Allow `codex agents --no-daemon` to use an embedded app server and open the command center without a shared server.
- Route `codex agents` through the normal daemon startup, eligibility, and compatibility checks, including embedded fallback where applicable.
- Return embedded sessions to the command center when canceling directory trust or archived-session confirmation.
## Testing
Add CLI coverage for `--no-daemon` before and after `agents`, plus an integration test that verifies embedded mode is used even when a daemon is running. Update archived-session tests to expect cancellation to return to the command center.
GitOrigin-RevId: 3bdf18a00456eae2e4d38103d12126e039d44119
## Why
Enabled rollout tracing could silently fail to initialize, and a terminal task status did not establish whether all recording had finished. Trace consumers need to distinguish a complete recording from a partial bundle, including when a task is interrupted.
## What changed
- Fail thread startup or resume if an enabled recorder cannot initialize, while cleaning up session resources.
- Stop recording after the first write or serialization failure and preserve that failure across shared producers.
- Append a closing record when the last writer handle is released without recording errors. Expose `recording_complete` in `state.json` independently of task success, and mark submission-channel closure as an aborted rollout.
- Reject replay logs with missing or reordered events, mismatched rollout IDs, events after completion, or missing or invalid JSON payloads. Valid prefixes remain replayable with `recording_complete` set to `false`.
## Testing
Add coverage for startup failure and recovery, shared-writer failures, finalization after child handles close, incomplete logs, and missing or malformed payloads. Extend session and CLI tests to check recording completion after shutdown, interruption, stream failure, and submission-channel closure.
GitOrigin-RevId: 30d62fa95912fb0442ad1199776d110884066c30
## What changed
- Add “System proxy” to `/experimental` for opting into macOS or Windows system proxy settings. Keep `respect_system_proxy` disabled by default.
- Update doctor’s macOS proxy guidance to point to `/experimental` and `codex features enable respect_system_proxy`, and tell users to restart Codex after changing the setting.
## Testing
Add snapshots for the experimental setting and doctor guidance, plus a Responses test verifying that `x-codex-beta-features` includes `respect_system_proxy` only when enabled.
GitOrigin-RevId: caa3e1a7cbe222069f35022b06c59da578b8a4dd
## 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
VTE versions before 0.54 lack the parser that safely ignores unknown OSC sequences. Terminal status reporting needs to account for the VTE backend even when the terminal identifies itself as GNOME Terminal or another application.
## What changed
- Track VTE backend versions independently of terminal application identity.
- Disable `OSC 7501` and `OSC 21337` status reporting when the detected VTE version is below 0.54. Preserve existing behavior for newer or unknown versions.
- Prefer `VTE_VERSION` over the terminal application version, treating empty or malformed values as unknown.
## Testing
Add regression tests for GNOME identity with VTE metadata, version precedence, and status protocol selection around the VTE 0.54 boundary, including unknown versions.
GitOrigin-RevId: 1aa57901d1b1457f9971c07cb51ec4554915ae3b
## What changed
Limit `--network-only` reports to effective configuration, network environment, provider HTTP reachability, and Responses WebSocket checks, skipping unrelated diagnostics such as database and MCP scans. Preserve configuration warnings and report configuration load timing.
If configuration loading fails, report the redacted configuration error and stop without probing guessed network targets.
## Testing
Add integration tests for check selection, recoverable configuration warnings, and configuration failures that send no probe requests or expose configuration values. Add snapshots for human-readable success and failure reports.
GitOrigin-RevId: 997616b6802813df751725f9538541c65bad7d71
## Why
Handshake probes can lose upgrade evidence when a subsequent read fails, and diagnostic output can expose URLs, server error messages, and close reasons containing sensitive values.
## What changed
- Retain successful upgrade status and allowlisted tracking headers, including on post-upgrade read failures.
- Return structured probe errors that distinguish typed TLS failures from failures with an unknown stage while preserving the underlying API error.
- Recognize empty close frames as immediate closes with code `1005`.
- Redact wire values from probe debug output and doctor error details, and remove URLs and raw errors from connection logs.
## Testing
Add local TLS and WebSocket fixtures covering certificate rejection, ordinary I/O failures, successful and rejected upgrades, immediate closes, malformed frames, header retention, and redaction. Add doctor output snapshots and error-detail redaction assertions.
GitOrigin-RevId: 1ee53720a7a752043943170d8e4da205ec4e55f3
## What changed
Extract executor startup into `codex-exec-server-cli`, shared by `codex exec-server` and the new standalone binary. Preserve executor arguments, authentication, configuration overrides, and sandbox helper dispatch across both entry points.
Build the standalone binary with `cargo build -p codex-exec-server-cli --bin codex-exec-server` and run it with `codex-exec-server --listen stdio`.
## Testing
Add standalone CLI parsing and help coverage, plus an integration test for version reporting, stdio initialization, filesystem reads, process execution, and sandbox helper re-execution when supported.
GitOrigin-RevId: ab3a81c6b91b6f45e4d72d8add2e01af8372e97f
## What changed
Add the disabled-by-default `omit_skill_descriptions` feature flag to omit descriptions from model-visible host, executor, and cloud skill catalogs while retaining names and locators. Adapt catalog introductions, usage instructions, and alias budget accounting to the selected policy.
Persist the description policy in catalog snapshots and refresh usage instructions when it changes. Ignore description-only edits in catalog deltas while descriptions are omitted.
## Testing
Add coverage for alias token budgets, policy changes with older snapshots, and suppressed description-only updates. Extend scenario snapshots to cover plugin visibility and catalog deduplication with descriptions omitted.
GitOrigin-RevId: 5bf1dcee8c04059c7a78998affc1efcdef8ec883
## What changed
- Recognize `policy_capacity_unavailable` in HTTP and streaming API errors and expose it as `policyCapacityUnavailable` through the app-server protocol and generated bindings.
- Display “Policy-restricted capacity is unavailable. Please try again later.” while preserving overload retry behavior based on `Retry-After`.
- Handle the new error in TUI overload rendering, reviewer retries, and error telemetry.
## Testing
Add coverage for HTTP and streaming error classification, retry advice, WebSocket terminal error attribution, protocol serialization, and TUI rendering with and without an upstream message.
GitOrigin-RevId: 1b9536fba1e11cc891dcf689aee35410d82f5412
## Why
`codex migrate-nfs-db` reported a successful migration when the database directory existed but contained no databases.
## What changed
Count databases that were migrated or already use DELETE journal mode. If none are found, print `No databases found.` instead of the migration success message.
## Testing
Extend the CLI integration test to cover an empty directory, a failure on a corrupt logs database after an earlier conversion, and a successful rerun that recognizes the converted database as already in DELETE mode.
GitOrigin-RevId: 16b109645925164f3af5d35a909417872cfa004f
## What changed
- Validate inherited options before and after the `queue` subcommand, with explicit errors for unsupported flags and positional prompts.
- Reject `--model` and `-c model=...` because queued messages use the thread's model.
- Allow `--cd` for local server startup, but reject it with `--remote`.
- Hide unsupported inherited options from queue help and clarify the scope of startup configuration overrides.
## Testing
Add regression coverage for unsupported options in both argument scopes, model configuration overrides, remote `--cd` conflicts, and queue help output. Preserve coverage for overrides that bypass a running local daemon.
GitOrigin-RevId: 703ba26f38930a01559847e66e1af3d0d338d1e9
## Why
Sandbox invocations without an explicit permissions profile and remote `exec-server` connections using ChatGPT auth need access to cloud-defined model providers and managed requirements. Cloud bootstrap requests must also respect local application network policy.
## What changed
- Bootstrap sandbox cloud config whenever managed config is included, even without an explicit profile. Skip bootstrap when `--sandbox-state-json` supplies the sandbox state.
- Load cloud config for remote executors beyond workload identity, while skipping forwarders and executors using stdin credentials, AWS SigV4, or agent identity auth. Honor `CODEX_API_KEY` selection so API key connections skip ChatGPT cloud config.
- Apply local application network policy during cloud bootstrap and activate effective application network policy before exec-server clients are created.
## Testing
Add coverage for cloud-defined providers in sandbox and remote exec-server invocations, API key bypass, local policy blocking bundle requests, cloud policy blocking remote registration, and bootstrap exclusions.
GitOrigin-RevId: e8bd6210751e96161f575ade309ebf41bf10f8b5
## What changed
- Add the disabled-by-default `skill_catalog_deltas` feature flag to append new and updated skills without repeating unchanged catalog entries.
- Share a cumulative metadata budget across executor, cloud, and host catalogs, preserving usage across turns and resume. Removals emit no update and do not refund budget.
- Rebuild the current catalog and reset its budget after compaction, including any required skill root mappings in updates.
## Testing
Add unit and integration coverage for update costs, shared source budgets, feature rollback, and catalog updates across resume and compaction, with a request-history snapshot.
GitOrigin-RevId: e88b4265d7361498113d43fdc2e0260a9f930bbc
## Why
The timeout fallback test depends on short wall-clock deadlines and a server-side sleep, making its timing dependent on thread scheduling.
## What changed
Use a paused Tokio clock and advance past the timeout only after the server receives `HEAD`. Keep the blocking server task alive until the probe consumes the `GET` response to prevent automatic clock advancement during socket I/O.
Assert both request lines and retain the check that the fallback returns `HTTP 405`.
GitOrigin-RevId: da7b2fa9c67e662648da8568ce7f8cfde153dc12
## What changed
Add `codex queue --resume` to resume an unloaded thread after queueing a message through the local daemon or selected `--remote` server. Already loaded threads are left running. If resumption fails, emit a warning while preserving the successful queue result.
Read only the thread status when checking whether to resume, allowing remote metadata to contain paths from another operating system.
## Testing
Extend CLI integration coverage for unloaded threads consuming queued messages, archived thread rejection, and successful queueing when another server owns the thread and rejects resumption.
GitOrigin-RevId: cc8aa3c11a37e990da36e6ff9a17934f73322e7b
## Why
NFS database migration rejected files with group or other access. Allow accessible databases to migrate while making the effects on file access explicit.
## What changed
- Preserve file mode bits during migration while requiring owner read and write permissions on replacement files.
- Before CLI consent, disclose that replacements belong to the current user and do not copy the original owner, group, or extended ACLs. Require explicit confirmation for files with permissions other than `0600`.
- Warn at Linux TUI startup when NFS databases need migration and permission confirmation. Inspect journal mode without accessing WAL shared memory or releasing another connection's locks.
- Allow five seconds to acquire the exclusive database lock during migration.
## Testing
Add CLI coverage for consent, access disclosures, and migration of `0644` files. Extend state tests for permission preservation, rejection of missing owner access, and interrupted migration recovery; snapshot the startup warning.
GitOrigin-RevId: 2d9c3663172c3e631a787dc1dc76db95c39e6aa1
## Why
Existing databases retain their journal mode, so selecting `DELETE` for new NFS databases leaves existing WAL databases unchanged.
## What changed
- Add the managed `unsafe_enforce_sqlite_journal_mode` requirement to migrate existing NFS databases before opening writable pools and require `DELETE` on each connection.
- Share migration code between startup and `codex migrate-nfs-db`, preserving WAL backups and resuming interrupted replacements, including lazily opened databases.
- Hold the migration lock through pool initialization and keep migration failures out of automatic corruption recovery.
- Preserve local logs behavior and skip legacy NFS logs cleanup when enforcement is enabled.
## Testing
Add coverage for requirement precedence, database settings, data and backup preservation across restarts, interrupted replacement recovery, refusal of active WAL databases, migration lock waiting, and local logs remaining in WAL mode.
GitOrigin-RevId: da41ec1b58b1ee8092591cdf8b358280928ff9d4
## Why
Stdio servers without `CODEX_MCP_PROTOCOL_VERSION` use the legacy handshake, even when they support MCP `2026-07-28`.
## What changed
- Add the disabled-by-default `mcp_connection_sharing` feature to enable discovery for eligible local stdio servers.
- Recover from failed or late discovery with a fresh handshake when needed, waiting for the previous helper to release resources before restarting.
- Retain a working legacy connection when an upgrade attempt fails for the same account, except on authentication errors.
- Keep tool catalogs separate by protocol and invalidate legacy catalogs when discovery negotiates the modern protocol.
## Testing
Add regression coverage for failed and late discovery, legacy fallback, protocol-specific catalog reuse, message limits, and Windows descendant cleanup.
GitOrigin-RevId: 36c675ef3b81d32fccf06ccbddda2312cfe602c9
## What changed
Remove `AuthProvider::resolve_auth_headers` and use `apply_auth_headers` as the async interface for header-only authentication. Migrate providers, callers, and existing tests to the shared interface, passing an empty `HeaderMap` when only authentication headers are needed.
Document that providers may refresh credentials asynchronously and that callers must use the returned header map so providers can remove superseded credentials.
GitOrigin-RevId: 42449de6fddd2be2c50c475c8e92628493197007
## Why
API keys with FedRAMP issuance markers previously used commercial endpoint defaults without a FedRAMP request header.
## What changed
- Recognize `sk-proj-fedramp-` and `sk-svcacct-fedramp-` prefixes as routing hints and send `X-OpenAI-Fedramp: true`, preserving the complete key for authentication.
- Select `https://gov.api.openai.com/v1` for default OpenAI API routing and `https://gov.chatgpt.com/backend-api/` for default ChatGPT backend requests, including model discovery and analytics.
- Preserve explicit endpoint overrides, including an explicitly configured commercial default URL.
- Resolve provider routing and authentication from the same credential snapshot, and apply key-dependent routing to realtime WebSocket startup.
## Testing
Add regression coverage for prefix recognition, unchanged key storage and authorization, provider credential precedence, endpoint overrides, credential rotation, model discovery, analytics routing, and realtime request preparation.
GitOrigin-RevId: a62576ce205c34e067532b8e6c0e431f87a157e2
## What changed
- 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
- 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
## Why
Provider errors with code `model_not_found` should end the turn immediately and preserve the provider's message instead of triggering retries.
## What changed
- Recognize `model_not_found` in HTTP 400, 403, and 404 responses and in streamed `error` and `response.failed` events.
- Preserve the provider message and any available HTTP status, and expose `modelNotFound` through the app-server protocol and generated schemas and SDK types.
## Testing
Add coverage for HTTP classification, statusless stream errors, and terminal failures without retries across HTTP, SSE, and WebSocket responses. Verify that `thread/read` preserves the error reported by the live notification.
GitOrigin-RevId: 88f824ac03c8c9669915b1e40c67b76c08326fbe
## What changed
- Add `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
## Why
Model output alone does not establish that an item entered conversation history. Treating every response item as accepted can include discarded attempts, while relying on a later request misses accepted final output when a turn ends or is interrupted.
## What changed
- Record `HistoryItemAccepted` events and retain Responses item IDs, generating missing IDs consistently across item events.
- Build thread conversation history from request inputs, compaction checkpoints, and explicit acceptance. Keep unaccepted output accessible through its inference call.
- Preserve inference provenance across retries and late response records without overwriting newer request or compaction snapshots.
- Mark turns with errors as failed. Bump trace schemas to version 2 and reject incompatible bundles and event schemas during replay.
## Testing
Add reducer coverage for discarded attempts with identical text, late responses, compaction, inherited context, and legacy bundle rejection. Add CLI integration tests that run `debug trace-reduce` after success, stream failure, and interruption followed by shutdown, including responses without provider item IDs.
GitOrigin-RevId: 8e387a91d9b3f704df82847d630e6f0b08f998b3
## What changed
Promote `bedrock_setup_wizard` to stable and enable it by default for eligible onboarding. Users can still disable it with `features.bedrock_setup_wizard = false`.
## Testing
Update onboarding coverage to check the enabled default and explicit opt-out. Remove the explicit opt-in from daemon startup tests so they exercise the default configuration.
GitOrigin-RevId: 5bd911088681a31d34aa444398e6d3f7d1d87955
## Why
When `-c` or `--config` appears at multiple command levels, Clap retains only the deepest scope's values, dropping earlier overrides.
## What changed
Collect config overrides from each command scope in order while preserving typed child arguments and their existing precedence. Arguments forwarded after `--` remain unchanged.
## Testing
Add regression coverage for overrides split across nested `mcp add` commands, forwarded `-c` arguments, and validation of an invalid override before `app-server` when another override follows it.
GitOrigin-RevId: 40c64eda866497e2f59491a523c6777a8bfe5d5f
Use `ConfigEditsBuilder` to persist a concurrent MCP server edit during OAuth discovery without launching another CLI process inside the HTTP timeout. Preserve coverage that the concurrent server and issuer-bound callback are saved, and assert that OAuth fails with the expected invalid authorization endpoint error.
GitOrigin-RevId: 41d782f9dbbc96d528e4990171bffd87e95f6e4f
## Why
Remote registry requests need to recover when credentials are rejected or rotated while `exec-server` is running. Concurrent requests should reuse refreshed credentials rather than refresh the replacement token again.
## What changed
- Add an `AuthProvider` recovery hook and retry registry registration, connection, and harness-key validation once after a `401` when the provider supplies replacement credentials.
- Use live ChatGPT authentication for remote `exec-server` and guard proactive and unauthorized refreshes so concurrent callers share the completed refresh.
- Allow executor credentials to retry when the parent has already supplied a valid replacement.
- Keep connection authentication, refresh, and retry within the original connection deadline.
## Testing
Add coverage for concurrent refreshes, stored and parent-supplied credential rotation, refresh failures, retry limits, and connection deadlines, plus a CLI integration test for refresh and credential reload in a running executor.
GitOrigin-RevId: 9ed533e410762c7ac8b7c0c30bb93fd20d96778b
## What changed
- Store `logs_2.sqlite` in `log_dir` when explicitly configured, unless a managed `sqlite_home` requirement applies. Keep other databases in `sqlite_home` and preserve the existing SQLite log location when `log_dir` is unset.
- Initialize and lock the selected log directory only when opening its database, so an unavailable directory does not prevent authentication commands from loading configuration. Share the cleanup lock across configuration clones and allow failed initialization to be retried.
- Leave existing logs in place. Read legacy logs for diagnostic submissions when the current query returns no logs, attaching them as `codex-logs-legacy.log`. Continue retention cleanup and page reclamation for both locations, with independent maintenance locks and filesystem checks.
## Testing
Add coverage for configuration routing and managed requirements, deferred initialization and lock lifetimes, authentication with an unavailable log directory, legacy log attachments, and cleanup of current and legacy databases.
GitOrigin-RevId: 48216694596d738eff1b3c5eef6c4e7ada6d0137
## What changed
Add `codex migrate-nfs-db` to replace configured SQLite WAL databases in place with validated copies in `DELETE` journal mode, retaining the originals and their sidecar files in backup directories. Stage conversion locally, check database integrity before installation, and support resuming an interrupted replacement.
Require confirmation and exclusive access, with all Codex instances stopped on every host until migration succeeds. The NFS mount must support cross-client POSIX locks. Reject unsupported file permissions and ACLs, and serialize migrations with a migration lock.
Support configuration overrides, `--profile`, and `--staging-dir`. Skip the logs database when `log_dir` is explicitly configured and leave databases already in `DELETE` mode unchanged. Reject remote mode.
GitOrigin-RevId: 7b48cc3a713113a3c09a2243e49b54258bef609d
## What changed
- Prefer an eligible account grant over saved enterprise credentials, with a fallback to saved enterprise sign-in during initial connection if the account grant is rejected.
- Remember rejected account grants per enterprise MCP registration across threads and report authentication failures as requiring reauthentication. Keep administrator configuration errors distinct from sign-in failures.
- Compare account grants independently of access and ID token rotation, recheck the latest identity eligibility after exchange, and retry once when the refresh grant changes.
- Make MCP authentication status reflect usable account grants, saved enterprise credentials, and completed connection failures.
## Testing
Extend regression coverage for enterprise sign-in failures and recovery, MCP authentication status, account grant identity across token refreshes, and retries after transient credential failures.
GitOrigin-RevId: eeac65f668d5d2d55e9d8bf4547fbcbdd6a6c42d
## Why
Managed stderr logs previously retained a tail only before a new launch, allowing logs to grow during a long-running process. Direct stderr writes could also block lifecycle operations on disk I/O.
## What changed
- Route managed app-server and updater logs through a shared nonblocking worker with a bounded queue. Drop records when the queue is full or a record exceeds 16 KiB, and avoid waiting for the worker at shutdown.
- Prune live logs when they exceed 1 MiB, preserving the latest 256 KiB in `.log.previous` before truncating the current file. Keep inherited stderr handles usable after truncation.
- Pause predecessor pruning during Windows updater handoff and resume it after a failed handoff only when ownership has been restored.
- Keep ordinary stderr output when managed logging has not been initialized.
## Testing
Add regression tests for stalled workers and queue overflow, tail retention, inherited append and nonappend handles, and pruning exclusion during updater handoff.
GitOrigin-RevId: b6301962b1180fa6cdb231a56edce2429dc20b54
## What changed
Store `RolloutItem::SessionMeta` and `RolloutItem::Compacted` payloads in `Box` values and update their producers, consumers, and test fixtures. Preserve the existing serialized rollout format.
GitOrigin-RevId: 59fcc4beb47d23160872dcb6e95ace9b142d3d11
## Why
Failed marketplace adds can leave temporary checkouts behind, and interrupted adds or upgrades can leave abandoned staging directories.
## What changed
- Share a staging guard across marketplace adds and upgrades so temporary checkouts are removed on completion or failure, including config-write rollback.
- Reclaim up to four abandoned directories per cleanup pass during add and upgrade operations. Use file locks to preserve active checkouts and operating-system-specific names to avoid reclaiming another platform's staging directories.
- Skip symlinks and unrelated entries, and report cleanup failures as warnings.
## Testing
Add regression coverage for failed adds, CLI and automatic-upgrade cleanup, cross-process ownership and abandonment, lock contention, bounded cleanup, and symlink handling.
GitOrigin-RevId: 20999da0eab861dfb8025aad5e9fba2bcaf818b8
## What changed
- Add `--cloud-skills-snapshot PATH` to load a cloud skill catalog and resource contents from JSON once at app-server startup, without contacting a live skill service.
- Expose snapshot skills through the native `skills.list` and `skills.read` interface, preserving aliases and prompt visibility. Reads remain available after the snapshot file is removed.
- Validate package boundaries, required resources, duplicate packages, and size limits; fail startup for missing or invalid snapshots.
- Keep frozen cloud catalog and read caches independent of live MCP resource changes.
## Testing
Add provider, cache, app-server, and core scenario tests covering validation, exact resource contents, authority boundaries, startup failures, and listing and reading frozen skills alongside a named executor.

## Why
Synchronous auth header construction could silently return no credentials when managed authentication became unavailable. Callers need an error to avoid sending requests with missing or partial authentication.
## What changed
- Make `AuthProvider::add_auth_headers`, `to_auth_headers`, and auth header telemetry fallible, and propagate failures through request and WebSocket setup.
- Return a transient error when managed authentication is unavailable, and preserve network policy denials through auth error conversion.
- Retry transient MCP authentication errors while treating build errors and policy denials as terminal.
- Cancel local MCP event streams before resolving authentication so cleanup still works when credentials become unavailable.
## Testing
Add regression coverage for rejected partial authentication, async header resolution, terminal auth errors without sending requests, managed account changes, MCP retry classification, and local stream cancellation after authentication becomes unavailable.

## Why
A fixed feature allowlist excluded other boolean feature overrides from daemon use. Feature mismatches could also silently fall back to embedded mode, while automatic startup could persist enabled overrides without confirmation.
## What changed
- Allow boolean feature overrides without a fixed allowlist and compare explicit overrides with the daemon's reported settings. Ignore removed features, treat unreported features as disabled, and include only mismatches in restart settings.
- Preserve saved daemon settings during automatic startup. Prompt on feature mismatches even when embedded fallback is allowed, letting users run without the daemon, confirm a managed-daemon restart, or cancel.
- Detect managed daemons during recovery, mark available restarts as recommended, and limit the displayed feature list to three entries plus a remaining count.
## Testing
Update compatibility tests for mixed overrides, removed and unreported features, unreachable daemons, and required versus optional attachment. Update recovery snapshots and the TUI integration test to exercise explicit embedded-mode selection.

## Why
Saving an API key does not validate it. Login and status messages should make clear that authentication is checked when a request is sent.
## What changed
Report `API key saved` after API key login and `API key configured` in `login status`. Both messages now explain when authentication is checked.
## Testing
Update the API key login integration test with snapshots for login and status output, while retaining assertions that the key is saved to `auth.json`.

## What changed
Add `codex app-server --print-startup-config` to validate local and cloud-backed configuration and emit the app-server version and configuration requirements as JSON without initializing environments, thread storage, or plugins. Configuration failures produce structured JSON errors and a nonzero exit status.
Support `--startup-sign-out` to remove account credentials and reload signed-out requirements, including recovery when cloud policy is unavailable. Reject sign-out for host-owned external authentication. Accept `--startup-client-info` to identify configuration and authentication requests.
Reuse configuration loading and account cleanup logic between startup discovery and the running app server.
## Testing
Add CLI integration coverage for configuration validation, project login restrictions, managed cloud requirements and failures, sign-out recovery, external authentication protection, and independence from locked or invalid history databases.

## Why
A replacement daemon PID can appear before the TUI observes the disconnect, allowing stale UI content to make the startup test advance too early. Cold Rosetta translation can also consume the startup deadlines for freshly extracted Intel macOS packages on Apple Silicon.
## What changed
- Wait for the reconnect transcript clear before sending `/status` in the daemon startup test.
- Warm both packaged CLI and app-server entrypoints with `--help` when testing `x86_64-apple-darwin` packages on `arm64` hosts. Give each warmup 180 seconds and fail fixture setup if either entrypoint cannot run.

## What changed
Launch managed app-server and updater processes directly through the shared background command helper, removing the macOS `taskpolicy -b` wrapper and its availability probe. Remove the associated launch-policy tests and macOS daemon-startup test serialization.
Retain the 30-second macOS readiness timeout because older updaters can pass background policy to replacement daemons during upgrades.

## What changed
Add the `multi_env_copy_file` feature flag, disabled by default and marked as under development, to the feature registry and configuration schema. Install the file-copy extension in app-server threads and CLI debug prompt construction when the flag is enabled.

## Why
Authorization server metadata can advertise scopes unrelated to the MCP resource. Using that list for discovery can request broader scopes than the resource requires.
## What changed
Update `rmcp` and use its initial scope selection during OAuth discovery: prefer scopes from the initial `WWW-Authenticate` challenge, fall back to protected resource metadata, and include `offline_access` when supported. Stop using the authorization server's general scope list as the discovered resource scopes.
## Testing
Add coverage for challenge scope precedence, resource metadata fallback, scope normalization, and exclusion of unrelated authorization server scopes. Add a no-browser login regression test for a preregistered client whose authorization server advertises neither scopes nor dynamic registration.
