## Why
Configured MCP servers must not be able to request user verification, even when they reuse the hosted apps server name. Local verification identity selection also needs to distinguish a user's workspace memberships.
## What changed
- Advertise `userVerification` only to the host-owned apps MCP server and cancel verification requests from other servers before prompting the client.
- Add `CodexAuth::get_chatgpt_account_user_id()` to read the access token's opaque `chatgpt_account_user_id` only when its workspace matches the selected account. Missing or malformed claims return no identity, without falling back to another user ID or breaking ordinary authentication.
## Testing
Add coverage for capability filtering, rejection of configured servers including those using the hosted apps name, and account-user identity selection with malformed or mismatched claims. Add an MCP round-trip test showing that verification waits for a client response even in full access mode, returns the supplied proof, and discards response metadata.

## What changed
- Use `decide_approval` for MCP elicitations, carrying the effective approval policy, reviewer, and synchronous-review requirement into the decision.
- Preserve unsupported form and URL elicitations for user review.
- Use `computer_use_review_required()` for review evidence, session policy, and turn metadata so model policy takes precedence over the legacy flag.
- Derive strict-review notifications from each assessment's review reason.
## Testing
Add coverage for model policy precedence, user and full-access modes, sensitive elicitations, independent code-mode and nested-tool policies, cached score reuse, and user review of unsupported elicitations.
GitOrigin-RevId: d0a9c40572dca7b3dbf876230d2162b72728084d
## What changed
- Let approval extensions choose between cached approval, synchronous review, and a user prompt for tool and permission requests, while core enforces mandatory Guardian and fresh-review requirements.
- Carry an optional `review_reason` on Guardian assessment events and use it to trigger strict-review notifications, retaining the fallback for older events.
- Require synchronous review when cached evidence has an unusable encrypted parent compaction.
## Testing
Add regression coverage for manual prompts and cached approvals with non-UTF-8 working directories. Update approval contributors in existing tests to use the decision API.
GitOrigin-RevId: a4e66416070bdaa881daa41429c49021629f44c1
Route `gpt-5.6-luna` POST requests through `luna_response` using the shared
classifier state in the guardian compaction and rollback test. This gives
HTTP classifier requests the configured mock score instead of treating them
as guardian review or parent requests.
GitOrigin-RevId: 3841705c7ed1ec564662c33f71e1c78e9b960c68
## What changed
Delete `codex-rs/app-server/README.md` and remove references to it from `AGENTS.md`, while retaining the requirement to update app-server docs and examples when API behavior changes.
GitOrigin-RevId: 664f38c4939a9784b1241225e5101b97ec4ae9e6
## Why
When no healthy pooled WebSocket is available, classification waits for a new connection to open and can stall on its handshake.
## What changed
- Use HTTP streaming when no healthy idle WebSocket is ready, and replenish the pool in the background with a five-minute cooldown after connection timeouts.
- Share concurrency limits and the sampling retry budget across both transports, and bound the wait for HTTP response headers.
- Cancel superseded requests while awaiting response headers and stop SSE polling when the consumer closes.
## Testing
Add coverage for HTTP fallback and recovery after cooldown, shared transport capacity, stalled response headers, and cancellation before headers or during body draining. Update sampler and extension tests to cover fallback after socket expiry, authentication changes, and transient failures.
GitOrigin-RevId: 0b23ccc1bfb2dfdbc8d2791d097706cd4dd44f39
## Why
Device-authenticated verification needs an app response outside automated approval and review. Previously, MCP user-verification requests were always cancelled.
## What changed
- Add typed `openai/userVerification` elicitations carrying a title, description, and challenge through core and app-server.
- Route verification to one connection enabled by trusted host activation. Restrict responses to that owner, exclude requests from replay, and cancel on disconnect or authentication changes, including account switches away and back.
- Return proofs in `content`, discard response metadata, and cancel malformed acceptances. Suppress verification response logging and analytics, and send only a generic verification notice to realtime.
- Keep the mode experimental and exclude it from stable schema exports. Capability advertisement remains disabled, and the TUI cancels verification requests.
## Testing
Add coverage for owner isolation, disconnect and authentication races, proof response handling, automated-review bypass, inactive-host cancellation, stable schema filtering, and realtime payload exclusion. Update the MCP integration test to verify that an activated request holds the tool until the client responds.
GitOrigin-RevId: c8c7b6691a3f7756682bbcca9def1df0d1feb906
## What changed
Route managed Windows app-server shutdown through `/daemon/shutdown` on the local control socket. Require the server's PID and acknowledge it before triggering shutdown through the existing drain logic. Enable the endpoint only for managed Windows launches via `CODEX_DAEMON_SHUTDOWN_SOCKET`.
Watch running-turn changes whenever shutdown is requested so socket-triggered shutdown can finish draining. Keep the updater's file-based shutdown mechanism and retain forced termination as the manager's timeout fallback.
## Testing
Add a transport test covering rejection of unmanaged shutdown requests and mismatched PIDs, plus acknowledgment before emitting the shutdown event.
GitOrigin-RevId: 3e95dc1914f61e8a131f9b6fd56b6c63688d1744
## What changed
Add `userVerification/status`, `userVerification/enroll`, `userVerification/delete`, and `userVerification/verify` behind the `experimentalApi` capability. Define request, response, proof, and typed error contracts, export their schemas, and document the API.
All four methods currently return `unavailable` with reason `providerUnavailable`; native verification operations are not implemented by this change.
## Testing
Add tests for experimental opt-in, typed provider unavailability, readiness serialization, and rejection of mismatched error reasons and native diagnostic payloads.
GitOrigin-RevId: a858ab41523c5acec7dbf3cfa7fcab693ac44a8c
## Why
Experimental context activation previously checked the provider and account eligibility without checking model support. Child sessions also inherited token-budget activation from their parent, even when starting fresh with a different model.
## What changed
- Add `ModelInfo.supports_experimental_context`, defaulting to `false`, and enable it for the bundled `gpt-6-astra` model. Require this capability when activating experimental context.
- Snapshot configured token-budget preferences before startup activation. Restore them for fresh child sessions before applying their starting model's defaults, while history forks retain their parent's activation.
- Pass unresolved token-budget preferences to child sessions so they can use their own model's prompts.
## Testing
Extend coverage for unsupported models, model-switch guidance under explicit and experimental activation, and child configuration from both active and inactive parents. Verify that omitted capability metadata defaults to `false`.
GitOrigin-RevId: 02df9e171682267232fa923d5ea3f7af36527808
## What changed
Replace `features.guardian_thread_context` with `features.guardianv2.thread_context` and update the configuration schema. The setting controls thread-owned context for synchronous and asynchronous Guardian, defaults to `false`, and remains independent of `features.guardianv2.enabled`.
## Testing
Update configuration tests to cover the nested setting, profile overrides, and enabling thread context while Guardian v2 is disabled. Migrate Guardian approval, history, and async scorer tests to the new configuration key.
GitOrigin-RevId: 54a91555eb68001e0adedc8a07bdbc5ea2273f9b
## Why
Calling `app/installed` with `threadId` and `forceRefresh: true` refreshed a separate runtime snapshot without updating the thread's tools for subsequent turns.
## What changed
Use the thread's current configuration and refresh its live app tools when a thread is specified. Account for the refreshed snapshot's model-visible tools when reporting `callable`. Requests without `threadId` continue to use a separate runtime for refreshes.
## Testing
Add integration coverage verifying that refreshed tools replace previous tools in subsequent model requests and can be called, and that a failed refresh preserves the last working tools. Extend thread configuration coverage to include forced refreshes.
GitOrigin-RevId: fc13e28a59da00af470cf25c0cde356504e1575b
## What changed
Capture the ID from `response.created` and pass it as `parent_response_id` in Guardian review and classifier request metadata. Clear the current response ID before sampling retries so tool reviews cannot inherit a failed response's ID.
Request Guardian credits with `guardian_credits_requested` on eligible parent requests. Remove the ticket protocol, transport attachment, and ticket-specific body redaction. Keep ordinary app-server client `parent_response_id` values inside `x-codex-turn-metadata` rather than promoting them to Guardian request metadata.
## Testing
Update coverage for HTTP fallback, WebSocket review reuse, missing response IDs, classifier transport retries, and code-mode yield/resume attribution. Extend app-server tests to verify client metadata placement over HTTP and WebSocket.
GitOrigin-RevId: c1665e56382ecec8d260fc2ca0ecd5e20b0b2391
## Why
Reverting a paginated thread can remove the turn context that records its resolved multi-agent version. Preserve that version so a model-selected V2 thread keeps its collaboration tools after reload or a server restart.
## What changed
Pass the live thread's `multi_agent_version` into the thread store and persist it in the replacement rollout's session metadata. When no live version is supplied, retain the existing metadata value. Document this guarantee for `thread/revert`.
## Testing
Add regression tests for model-selected V2 across live reload and cold resume, plus metadata preservation for `V1`, `V2`, and `Disabled` across repeated reverts.
GitOrigin-RevId: bd7d4d76a50d23da16caa2a0631acf10bfa49629
## What changed
Remove the `codex mcp-server` subcommand and the standalone `codex-mcp-server` crate, including its tests, interface documentation, build dependencies, and run recipe.
## Testing
Update the strict configuration test to use `codex exec hello`, preserving coverage for rejecting unknown configuration overrides.
GitOrigin-RevId: 8688b1f41862d7c2073ea2812a257c0087c55d9c
## Why
Plugin updates made by another process do not notify a loaded session's hook runtime, leaving it with stale hooks.
## What changed
Compare the current plugin hook sources and load warnings with those retained by the hook runtime during turn construction. Refresh hooks when either differs so existing sessions pick up external plugin updates.
## Testing
Add an app-server regression test that updates the shared plugin store without notifying the server and verifies that successive turns in the same thread run the installed hooks across an upgrade and a rollback.
GitOrigin-RevId: d3a2653ac4c069d9d8a02f30e21e4506d76a091c
In `guardian_v2_routes_scoped_tool_approvals`, wait for the reviewed
thread's `codex_turn_event` before shutting down the app server. Use the
returned event for assertions instead of looking it up in the
post-shutdown analytics snapshot.
GitOrigin-RevId: 3ba4d37838852842c6caf7701d3abf7c89166a98
## Why
Background and empty-input turns could lack a `root_turn_id`, and detached memory requests omitted turn identity entirely. Tasks without a root could also adopt one from coalesced mailbox input.
## What changed
- Set `root_turn_id` to the task's turn ID at task start unless an inherited or recovered root is already present.
- Stop assigning roots from mailbox input or steering an active turn.
- Give detached memory requests a fresh UUID for both `turn_id` and `root_turn_id`, included in turn headers and client metadata while still omitting session and thread identity.
## Testing
Extend assertions for background turns, empty input, goal continuations, manual compaction, and detached memory requests. Exercise mailbox coalescing with both independent and inherited roots to verify the task keeps its established root.
GitOrigin-RevId: ee0f2f1b43542a9f5884f694c1d94341b476779c
## Why
Clients need a per-thread Daybreak toggle that survives restarts and can be
restored on resume without changing the access program of an active or future
turn.
## What changed
- Add experimental `daybreakEnabled` support to `thread/metadata/update` and
expose the saved value on thread responses.
- Store the preference in SQLite, including for threads without a first turn,
and preserve it through reads, resumes, reconciliation, and restarts.
- Copy the preference when forking a thread while keeping subsequent updates
independent.
- Keep `daybreakEnabled` separate from the per-turn `cyberAccessProgram` field;
app-server does not derive one from the other.
## Testing
- Cover persistence across restarts, cold reads, reconciliation, and forks.
- Verify metadata updates do not alter the access program of active or later
turns.
GitOrigin-RevId: bcf987a9fcd7b0ac8a88b1c8f0df06b33ed8ad6e
## Why
Guardian reviews must not lose user authorization constraints or reuse an
unreadable or incompatible parent checkpoint after compaction.
## What changed
- Retain bounded excerpts of oversized root user messages across compaction,
resume, and rollback, and recover excerpts from legacy Guardian history when
available.
- Require thread-owned Guardian review sessions and asynchronous scoring to
reuse only non-empty checkpoints produced by a compatible review model.
- Fail closed instead of reviewing without the required checkpoint when reuse
is disabled, compatibility is unknown, or checkpoint content is unusable.
## Testing
Expanded retained-context, review-session, asynchronous-scoring, and app-server
coverage for oversized instructions, legacy recovery, model incompatibility,
missing content, resume, rollback, and disabled checkpoint reuse.
GitOrigin-RevId: f30d837197e0d838e656a632109f490c38208f5e
## What changed
- Configure the CLI and app server to use `tikv-jemallocator` on
`x86_64-unknown-linux-musl` and `aarch64-unknown-linux-musl`.
- Keep the dependency and global allocator selection scoped to those targets.
GitOrigin-RevId: 93c54c90d9acb7e48edffd032cd8ec685a782210
## Why
Guardian reviews need the original user instructions even when compaction or
transcript selection removes them from the active conversation window.
## What changed
- Capture complete user messages in host-owned retained context and include them
as ordered authorization evidence alongside verified answers.
- Omit oversized instructions atomically and emit an explicit incomplete-evidence
notice instead of exposing a potentially misleading partial permission.
- Mark user messages inherited by forked agents so they remain model-visible
without becoming child-local authorization.
## Testing
- Cover retained instructions across compaction, resume, rollback, and agent
forks, including oversized evidence and legacy context behavior.
GitOrigin-RevId: 97122509d818c90d2f87c6a1b29c99c05ad0316e
## Why
Guardian approval actions can contain paths from a remote executor whose path convention differs from the host, such as Windows paths reviewed on a POSIX host. Converting those paths to host-native absolute paths prevents the action from being reviewed.
## What changed
- Render command working directories using the executor's reported path convention, and preserve URI-backed paths for attribution.
- Carry foreign command and patch paths through Guardian events and app-server schemas as legacy path strings.
- Bound remote plugin attribution within the overall review deadline and reject Guardian action payloads that exceed the review byte limit.
## Testing
- Cover Windows and POSIX executor path rendering, foreign patch paths, protocol round trips, oversized payload rejection, and remote Guardian review context.
GitOrigin-RevId: 38be0fcdac897139519e74e077eb5cb4f8f8017e
## Why
Guardian reviews for delegated workers need the current root instructions and verified answers even after the parent context is compacted. Approvals must also become stale when that root authorization changes.
## What changed
- Build bounded root review evidence from retained context, preserving source order and answer scope while prioritizing user instructions over optional assistant context.
- Recover retained instructions from Guardian history after compaction and mark authorization incomplete when required instructions or answers are unavailable.
- Version root authorization in synchronous and reusable review sessions so an allow result is cancelled when its evidence changes.
- Strip parent-only Guardian approvals when forking worker history in retained-context mode.
## Testing
- Cover retained and legacy context modes, oversized evidence, message limits, parent compaction, and authorization changes during review.
GitOrigin-RevId: 658219b7cee08f2752adcea9966268fd21727976
## What changed
- Parse the optional `[browser_use].allow_webmcp` boolean from managed requirements and preserve requirement-layer precedence.
- Return the policy as `browserUse.allowWebmcp` from `configRequirements/read`, including explicit `true`, explicit `false`, and `null` when omitted.
- Update the generated JSON and TypeScript protocol schemas.
## Testing
- Cover parsing, invalid values, layered overrides, and app-server response serialization.
GitOrigin-RevId: a3fd7d1a6f838bb3ab0ac2a644409101a2338ca6
## Why
Packaged clients need to pair a staging OAuth client ID with the matching
issuer. The issuer override was previously limited to debug builds.
## What changed
- Apply `CODEX_APP_SERVER_LOGIN_ISSUER` in all builds when it contains a
non-empty value.
- Keep `CODEX_APP_SERVER_DEV_OPEN_APP_URL` debug-only.
## Testing
Exercise the complete app-server OAuth flow with the issuer and client ID
overrides, including authorization, token exchange, and login completion.
GitOrigin-RevId: 13d290b9dae689cd811361b1b549953a3b52db42
## Why
Cold `thread/resume` configuration loading can call back into the host. Holding the global metadata permit during that work blocks unrelated thread metadata updates and MCP requests.
## What changed
- Release the metadata permit while loading configuration for a cold resume.
- Reacquire the permit and reload the resolved thread history before startup.
- Reload configuration when persisted metadata, settings, or the history working directory changed during the unlocked interval.
- Rejoin a thread that another request resumed concurrently, and avoid reopening threads that were archived or deleted.
## Testing
Add coverage for unrelated metadata and MCP requests during a blocked config load, concurrent resume mutations, and the extra history read required for non-local thread stores.
GitOrigin-RevId: 8cbd3868eeff84968765b1e3dbc7590ebe5fa892
## What changed
- Add optional per-model Guardian modes for computer use, shell, code mode,
file changes, MCP, network, and permission requests.
- Apply disabled, synchronous, or adaptive review by action category while
preserving legacy configuration when model policy is absent.
- Bind cached risk scores to the active model policy, thread settings, and
environment selections so outdated scores cannot approve later actions.
- Keep unknown review modes on the synchronous path and ignore unknown policy
fields for forward compatibility.
## Testing
- Cover policy serialization, legacy fallback, scoped tool classification,
disabled categories, and score invalidation after policy changes.
GitOrigin-RevId: f334a5f4fffb198da66cde3a400233e0df650516
## 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
## Why
A pending remote control enrollment could prevent the app server from exiting
after stdio EOF, leaving resources such as thread writers held by the process.
## What changed
- Give remote control its own child shutdown token and cancel it before draining
RPCs when the stdio connection closes.
- Interrupt enrollment requests that require network access after shutdown has
begun, while still allowing in-memory or persisted enrollments to be enabled
and durably saved.
## Testing
- Cover stdio shutdown during a blocked enrollment and verify that another app
server can acquire the released thread writer.
- Cover durable enablement after shutdown with in-memory, persisted, and missing
enrollments.
GitOrigin-RevId: ef9ab49672f273a4cf8257188454a154c03088bd
## What changed
- Add the `codex-attachment-store` crate with storage-neutral attachment metadata, references, errors, and an asynchronous persistence interface.
- Provide an inline implementation that preserves attachment bytes as media-typed base64 data URLs.
- Inject the store into `ThreadManager`, expose it to consumers, and retain inline storage as the default for existing entry points.
## Testing
- Verify inline storage round-trips binary, text, PNG, and JPEG data.
- Verify attachment debug output redacts URLs while retaining file IDs.
GitOrigin-RevId: 7688dcd3c89d7540ed2398f3e7c63881fbfcda97
## What changed
- Emit a connection-scoped `deprecationNotice` when `review/start` uses
`delivery: "detached"`, including when validation later rejects the request.
- Preserve detached review behavior while directing callers to use `thread/start`
followed by an inline review for a separate review thread.
- Document the deprecation and migration options in the app-server protocol and
README.
## Testing
- Cover the notice for accepted and rejected detached reviews.
- Verify that omitted, null, and inline delivery do not emit the notice.
GitOrigin-RevId: 4234a09d2bb7ef8053091580175dc8cbe8d7512c
## Why
An empty tool map does not distinguish a successfully returned empty catalog from a server whose startup or tool discovery failed.
## What changed
- Add nullable `toolsError` to each `mcpServerStatus/list` entry when no catalog is available because startup or tool discovery failed.
- Keep `toolsError` null for returned catalogs, including cached and empty catalogs, and continue returning healthy servers when another server fails.
- Update the protocol schemas and generated TypeScript type.
## Testing
- Extend the app-server status integration test with a broken MCP server and verify its error without losing the healthy server's inventory.
GitOrigin-RevId: 30b4ca4d9a45cec6998f5f626d3fddbee90a525d
## Why
Loaded threads can retain their previous configuration after a local plugin is
installed, preventing the plugin's bundled MCP servers and pending user-config
changes from taking effect in the current session.
## What changed
- Reload user configuration for loaded threads after installing a local plugin.
- Refresh MCP and hook runtimes only after the new configuration is applied.
- Keep installation successful if configuration reload fails, while logging the
failure.
## Testing
- Verify an installed plugin's MCP tool can be called from a thread that was
started before installation.
- Update the hook runtime test to verify installation applies a staged hook
configuration change to the loaded session.
GitOrigin-RevId: 63f5a5c7f16303e51cf940e8d9dc3b45c50ae2a9
## Why
Guardian can reuse an opaque parent compaction only when the checkpoint's
recorded producer hash matches the scoring model. Missing or incompatible
provenance must not allow an asynchronous score or cached approval to omit
compacted context.
## What changed
- Record the producing model's compatibility hash on compaction history items
and expose the latest checkpoint hash through conversation snapshots.
- In thread-owned context mode, fail closed and require synchronous review when
checkpoint reuse is enabled but the latest checkpoint is incompatible or has
unknown provenance.
- Reject incompatible checkpoints in the sampler while preserving the legacy
context behavior.
## Testing
Add coverage for local, remote, resumed, compacted, and rolled-back histories,
including matching, mismatched, missing, and empty compatibility hashes.
GitOrigin-RevId: 1ce959cb276edc602fd7dfa442133c7fe5e53857
## Why
Guardian authorization reviews need host-verified `request_user_input` answers to
remain aligned with thread history across compaction, resume, and rollback.
## What changed
- Record verified question-and-answer pairs in retained thread context when
`GuardianThreadContext` is enabled, and source both local and delegated Guardian
review evidence from that context.
- Preserve complete answer records within the evidence budget. Mark authorization
context incomplete when records are unavailable or oversized, and defer cached
fast approvals in that case.
- Keep the existing runtime-only answer path for threads that do not enable the
thread-owned context.
## Testing
- Cover answer retention through compaction and resume, removal after rollback,
source-call eviction, oversized answers, delegated review evidence, and legacy
behavior.
GitOrigin-RevId: 01f6f4541515434a0d00fdde318ff59f2f8bd2eb
## 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
## What changed
- Add `originator` to plugin measurement inputs and emitted analytics events.
- Populate it from the turn originator when recording plugin measurements.
- Extend analytics tests to verify the originator is preserved in event payloads.
GitOrigin-RevId: 9998f829760222fc690dc8a10324794b5da27220
## Why
Computer-use-only Guardian scoring should follow the active model's REPL
auto-review requirement, including when the model changes within a live thread.
## What changed
- Run computer-use scoring and fast approval decisions only when the active
model sets `node_repl_auto_review_required`.
- Invalidate prior or in-flight scores when a model switch skips scoring, so
switching back to a reviewed model cannot revive a stale decision.
## Testing
- Cover model switches for both `node_repl` and `cua_repl` MCP servers.
- Verify skipped scoring and stale-score rejection across requirement changes.
GitOrigin-RevId: 46aec4d017bea8f135b435bcd769b87369b8ce95
## What changed
- Add `application.network` managed requirements with exact-domain allow/deny
rules, default-enabled behavior, domain normalization, and normal managed TOML
precedence.
- Return the policy separately from agent network requirements through the
experimental `configRequirements/read` API. The endpoint reports the policy
but does not enforce it.
- Export the new protocol types and schemas, and document the TOML format.
## Testing
- Cover parsing, validation, normalization, layered precedence, and cloud
requirement composition.
- Verify app-server responses, defaults, separation from agent policy, and
rejection of invalid domains.
GitOrigin-RevId: 563eeed296d9748430b819797204a44a8db92f3b
## Why
Selected plugin MCP servers may be skipped after the optional startup grace
period. When a user explicitly mentions a plugin or MCP server, the turn should
continue waiting so the requested tools are available to the model.
## What changed
- Track explicitly mentioned plugin IDs and MCP servers across later samples,
steered input, and same-turn restarts.
- Require matching selected-plugin MCP servers to finish startup before
capturing the tool catalog, while leaving unmentioned servers optional.
- Match `plugin://` identities independently of display names and ignore
targeting query parameters such as `app` and `browserFamily`.
## Testing
Added coverage for linked and structured plugin mentions, direct and batched
capability discovery, delayed environment attachment, steering, and same-turn
restarts.
GitOrigin-RevId: c509ef8df45df1a7edb0da6afdb2682dc53a4de8
## Why
The managed app-server daemon and automatic TUI attachment were limited to
Unix, so Windows users could not share a background server across Codex
sessions.
## What changed
- Enable daemon lifecycle commands, `codex agents` startup, and AF_UNIX daemon
discovery on Windows.
- Require Windows daemons to start non-elevated and verify the discovered
socket directory and peer before connecting.
- Preflight detached process support, preserve path-based environment settings,
and keep daemon processes out of the launching project's working directory.
- Fall back to an embedded server when an implicitly discovered daemon cannot
connect, while preserving errors for explicit remote endpoints and bypassing
daemon reuse when `CODEX_EXEC_SERVER_URL` is set.
## Testing
Add coverage for Windows launch restrictions and socket validation, implicit
connection fallback, executor selection, daemon discovery, and the agents
dashboard startup result.
GitOrigin-RevId: e7fd63cf8690bcca8b5155266416f31f2f792aa2
## What changed
- Add the experimental `Thread.environments` field with each selected environment's ID, working directory, and runtime workspace roots.
- Populate the field from live thread state in start, resume, read, list, and unarchive responses. Use `null` for unloaded threads and an empty list when a loaded thread has no environment selection.
- Document that the field reports selection rather than connection status and does not affect executor selection or resume behavior.
## Testing
- Cover selection updates, unloaded and resumed threads, loaded pathless unarchives, and clients that subscribe after environment connection notifications.

## 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
- Remove the per-thread `RealtimeConversation` feature check when starting a realtime session.
- Retain `features.realtime_conversation` as a removed compatibility setting that has no effect, even when set to `false`.
- Document the always-available behavior for `thread/realtime/start`.
## Testing
- Cover realtime startup on forked and cold-resumed threads with the legacy setting absent, disabled, or enabled.

## Why
When ordinary included usage is exhausted, eligible users need a way to keep working with the backend-provided Luna Reserve quota and return to their previous model once ordinary usage recovers.
## What changed
- Automatically switch eligible TUI tasks to Luna Reserve after an authoritative account usage read, preserving the prior model and reasoning effort per task.
- Restrict model selection while on Reserve to its supported reasoning levels, keep queued turns on the accepted model, and restore the saved model after a fresh read confirms recovery.
- Surface Reserve usage in the composer and `/status`, and expose `normalModelSlug` in app-server rate-limit snapshots so clients can use the associated model's display metadata without changing the request model.
- Poll account limits more frequently near exhaustion and retain compatibility with app servers that only accept the legacy null request parameters.
## Testing
- Added coverage for Reserve entry, queued-turn handling, task reconstruction, recovery authorization, account changes, model selection, usage rendering, and banner dismissal.

## Why
Detached Windows processes cannot receive console signals, so app-server daemons
need another way to enter the existing graceful and forced shutdown flow.
## What changed
- Watch the path in `CODEX_DAEMON_SHUTDOWN_FILE` for a request addressed to the
current process, and consume only a matching PID.
- Race daemon shutdown requests with Ctrl-C on Windows while leaving unmanaged
launches on the existing console-signal path.
- Exercise the SIGTERM-equivalent graceful and forced WebSocket shutdown cases
on Windows.
## Testing
Added unit coverage ensuring inherited control paths and malformed requests
cannot consume another process's shutdown request.

## What changed
- Accept optional `account/rateLimits/read` capabilities for Luna Reserve support
and lightweight background polling while preserving omitted and `null` params.
- Forward the Luna Reserve capability only for eligible ChatGPT sessions, and let
lightweight polls skip the separate reset-credit detail request.
- Return the backend's `ordinaryUsageAllowed` decision only when its account and
user identity match the active session.
## Testing
- Cover capability defaults, eligible and restricted authentication modes,
lightweight polling, identity filtering, and backend permission handling.
