• [codex] Remove hardcoded app ID filters (#28947)

  ## Summary
  
  - remove the duplicated originator-specific connector ID denylists
  - stop filtering connector directory/accessibility results and
  live/cached Codex Apps MCP tools by hardcoded connector ID
  - remove the now-unused `codex-login` dependency from
  `codex-utils-plugins`
  - update regression coverage so formerly blocked connector IDs are
  preserved
  
  ## Why
  
  The client-side policy was duplicated across crates, used opaque IDs
  without ownership or expiry information, and could drift between app
  listing and MCP tool behavior. Server-provided visibility,
  authorization, plugin discoverability, accessibility, enabled-state
  handling, and consequential-tool approval templates remain unchanged.
  
  ## Validation
  
  - `just fmt`
  - `just bazel-lock-update`
  - `just bazel-lock-check`
  - `git diff --check`
  - confirmed the final diff contains no hardcoded denylist symbols
  
  A targeted `codex-mcp` test build spent an unusually long time in local
  compilation/linking. Its first attempt exposed a test-only `PartialEq`
  assertion issue, which was corrected. A follow-up non-linking `cargo
  check -p codex-mcp --tests` was still running when this draft was
  opened; CI should provide the complete Rust validation.

• Make auto-review on-request prompt more proactive (#26496)

  ## Why
  
  `on-request` approval policy text is currently tuned for user-reviewed
  approvals. For auto-reviewed productivity runs, likely sandbox blocks
  should be escalated earlier so commands that need remote services,
  authentication, or other out-of-sandbox access do not first fail or hang
  inside the sandbox.
  
  ## What changed
  
  - Adds a separate `on_request_auto_review.md` permissions prompt
  selected for `AskForApproval::OnRequest` with
  `ApprovalsReviewer::AutoReview`.
  - Keeps the normal user-reviewed `on-request` wording unchanged.
  - Makes the `When to request escalation` bullets more explicit about
  likely sandbox blocks, network access, remote
  auth/cluster/cloud/database access, out-of-sandbox environment access,
  git operations that may write lock files, and short-timeout reruns after
  likely sandbox-blocked attempts.
  - Omits approved command prefix and `prefix_rule` guidance for the
  auto-review on-request prompt.
  - Adds prompt tests covering the auto-review path, normal on-request
  wording, and inline permission request behavior.

• Add app-server current-time impl (varlatency 3/n) (#28835)

  ## What
  
  Server should request:
  
  ```
  {
    "id": 42,
    "method": "currentTime/read",
    "params": {
      "threadId": "11111111-1111-1111-1111-aaaaafdc2c11"
    }
  }
  ```
  
  Client should respond with something like:
  
  ```rust
  {
    "id": 42,
    "result": {
      "currentTimeAt": 1781717655
    }
  }
  ```
  
  ## Why
  
  Sessions configured with `clock_source = "external"` need a
  thread-specific external time source before inference. The system clock
  remains the default production provider.
  
  ## Validation
  
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-app-server --test all

• apply-patch: carry paths as PathUri (#28854)

  ## Why
  
  Allows the model to edit files that are hosted on a different OS than
  where app-server is running.
  
  ## What
  
  * Use `PathUri` for apply_patch-internal data structures
  * Limit `PathUri` -> `AbsolutePathBuf` conversion to cases where the
  inferred path convention matches the host OS, allows requiring valid
  paths to pass to perms check
  * Adds `PathConvention::path_segments()` for iterating over path
  segments regardless of OS
  * Handle cross-platform relative paths in path filename parsing for
  sniffing a shell
  * Ensure we can apply patches in the wine e2e test

• [codex] Cache plugin metadata for tool suggestions (#27812)

  ## Why
  
  `built_tools` runs for every sampling request, and local plugin
  discovery was repeatedly rereading plugin manifests, skills, MCP
  configuration, and app declarations to build the same tool-suggest
  metadata.
  
  That source-derived metadata is stable until the existing plugin manager
  reloads its cache. Runtime eligibility still needs to reflect the
  current install, disable, policy, app-overlap, and authentication state.
  
  ## What changed
  
  - Add a bounded, in-memory tool-suggest metadata cache owned by
  `PluginsManager`.
  - Key cached metadata by plugin identity and source, while applying
  authentication routing each time the metadata is projected.
  - Invalidate the metadata alongside the existing loaded-plugin cache,
  including its normal configuration, marketplace refresh, and
  remote-installed-plugin invalidation paths.
  - Guard against an in-flight load repopulating stale metadata after
  invalidation.
  - Keep marketplace membership and all runtime eligibility filtering live
  rather than introducing a separate catalog or revision model.
  
  ## Impact
  
  Repeated sampling requests reuse already-loaded plugin capability
  metadata while retaining the existing plugin-manager lifecycle as the
  single freshness boundary.
  
  ## Validation
  
  - `just test -p codex-core-plugins` — 252 passed
  - Added focused coverage for cache invalidation and authentication
  reprojection.

• current time reminders impl for system clock (varlatency 2/n) (#28824)

  Stacked on #28822.
  
  ## Summary
  
  - add a host-injectable current-time provider with a built-in system
  implementation
  - record UTC developer reminders in history immediately before due model
  requests
  - keep cadence state per session and force a refresh after compaction
  
  This does NOT include the app server client <-> server clock logic. This
  PR is only for the reminder message & system clock that will be used in
  prod.

• [codex] Make thread store turn filter optional (#28949)

  Make `ListItemsParams::turn_id` optional so callers can list persisted
  items across an entire thread or narrow the result to one turn. This
  aligns the thread-store API and documentation with thread-wide item
  listing while preserving the optional turn-filter behavior for
  implementations.

• [codex] rollout budget implementation (varlength 2/N) (#28494)

  ## Stack
  
  Depends on #28746. This PR implements shared rollout-budget accounting
  and model-visible reminders using the configuration defined in #28746.
  
  # Description / Main changes to Core:
  
  `AgentControl` will now be the area where "rollout level" features &
  accounting will have to live. It is incorrectly named for this
  responsibility, but I think it can hold all the necessary shared state &
  features (rollout token budget, mutliple thread interruption
  responsibilitym etc)
  
  In this PR, we have one "token ledger" that each thread will subtract
  from when sampling. The "charge" will occur when response.completed() is
  done and the calculation will be done on the responses api usage
  carrier. The calculation will weigh sampling and pre-fill tokens as
  specified.
  
  Every time the budget crosses the configured reminder threshold, a
  developer message is appended before the thread's next request
  
  This remaining budget will _always_ be restated/reminded after a
  compaction event.
  
  Expiration and fan-out interruption will be in the stacked follow-up
  (and also live in Agent Control).
  
  ## Reminders
  
  "You have weighted {session_tokens_left} tokens left in the shared
  session token budget."
  
  The first request in each thread context receives the current remainder.
  Later reminders are emitted after aggregate weighted usage crosses a
  configured interval. If several intervals are crossed before a thread
  sends another request, Core inserts one reminder with the latest
  remainder.
  
  Compaction response usage is charged before the next context starts. The
  next reminder is appended after the compaction summary, leaving the
  initial context content stable.
  
  ## Tests
  
  Integration coverage verifies:
  
  - weighted output and non-cached input accounting
  - initial and periodic reminders
  - shared accounting between a root and sub-agent
  - post-compaction remainder and message placement
  
  Local checks:
  
  - `just fmt`
  - `just test -p codex-core rollout_budget`
  - `git diff --check`
  
  The full workspace test suite was not run locally.

• Synchronize realtime notification test requests (#28946)

  ## What
  
  Deliver the scripted realtime notification batch after the assistant
  text append request instead of after the preceding developer text append
  request.
  
  ## Why
  
  The batch ends with an upstream error that closes the realtime
  conversation. When it is emitted after the developer append, it races
  the subsequent assistant append: the app-server RPC can acknowledge the
  append before its downstream WebSocket send completes, and the test
  intermittently observes three requests instead of four.
  
  Making the fake server wait for the assistant append before emitting the
  terminal batch establishes the ordering the test asserts without sleeps
  or production-code changes.
  
  ## Validation
  
  - `git diff --check`
  - CI (the failure is timing-dependent and most reproducible in the
  Windows Bazel shard)

• [codex] Fix Windows sandbox runtime ACL refresh (#28943)

  ## Why
  
  Codex Desktop repairs sandbox-user read/execute access for binaries
  copied to `%LOCALAPPDATA%\OpenAI\Codex\bin`, but Computer Use launches
  its bundled Node runtime from `%LOCALAPPDATA%\OpenAI\Codex\runtimes`.
  
  On fresh Windows installations, `CodexSandboxUsers` may therefore be
  unable to execute the bundled Node binary. The command runner starts,
  but `CreateProcessAsUserW` fails with error 5 (`ACCESS_DENIED`), causing
  the Node REPL to exit before Computer Use can discover applications.
  
  This is a follow-up to #21564, which added the original runtime `bin`
  ACL repair.
  
  ## What changed
  
  - Expand the Codex Desktop runtime ACL roots from only `bin` to both
  `bin` and `runtimes`.
  - Apply the existing inherited read/execute ACL repair to each runtime
  directory when it exists.
  - Rename the setup helper to reflect that it now handles multiple
  runtime paths.
  
  ## Validation
  
  - `cargo fmt -- --check`
  - `just test -p codex-windows-sandbox` was run: 113 tests passed and
  five environment-dependent legacy execution tests failed because
  `CreateRestrictedToken` returned error 87.

• [codex] Initialize exec-server OpenTelemetry at startup (#25019)

  ## Summary
  
  - Initialize stderr tracing and the configured OpenTelemetry provider
  for local and remote `codex exec-server` startup.
  - Instrument the local and remote server entrypoints with a root runtime
  span.
  - Keep raw Noise environment, registration, and stream identifiers out
  of exported spans while preserving them in local debug events.
  - Keep telemetry setup in a focused CLI module instead of growing the
  top-level command entrypoint.

• Fix goal-first live threads missing from thread/list (#28808)

  Fixes #28263.
  
  ## Why
  
  When a thread starts with `/goal`, the goal extension can update SQLite
  goal state before the thread has any user-turn rollout items.
  `thread/list` and `thread/search` rely on persisted listing metadata, so
  a goal-first live thread could be absent from app-server listings after
  restart even though the goal itself existed.
  
  This regressed when goal handling moved out of core: the core path wrote
  the goal update through the live thread rollout path, while the
  extension-backed app-server path only updated goal state and emitted the
  live notification.
  
  ## What
  
  - Add `GoalSetOutcome::thread_goal_updated_item()` so the goal extension
  owns the canonical `ThreadGoalUpdated` rollout item shape.
  - Expose a narrow `CodexThread::append_rollout_items()` helper that
  appends through the live thread and keeps derived SQLite metadata in
  sync.
  - When app-server sets a goal on an active live thread, persist the goal
  update through that live-thread path.
  - Add an app-server regression test that starts a live thread with
  `thread/goal/set` and verifies it appears in state-DB-only
  `thread/list`.
  
  ## Verification
  
  - `env -u CODEX_SQLITE_HOME just test -p codex-app-server
  goal_first_live_thread_appears_in_state_db_thread_list`

• Scope MCP sandbox metadata to server environment (#28914)

  Scope MCP sandbox metadata to the MCP server's owning environment.
  
  Previously, `codex/sandbox-state-meta` always used the turn's primary
  cwd and rebuilt a legacy sandbox policy from that cwd. That can be wrong
  for MCP servers owned by a different execution environment.
  
  This now sends the owning environment cwd as a `file:` URI in
  `sandboxCwd`, keeps `permissionProfile` as the permission source of
  truth, and omits sandbox-state metadata when a non-default server
  environment is not selected for the turn. Local/default MCP servers keep
  the existing fallback cwd behavior.
  
  Tests:
  - `just fmt`
  - `just bazel-lock-update`
  - `just bazel-lock-check`
  - `just test -p codex-mcp`
  - `just test -p codex-core mcp_sandbox_cwd`

• Recover exec process stdin writes (#28895)

  ## Summary
  
  Remote stdio MCP servers send tool calls by writing JSON-RPC bytes
  through `process/write`.
  
  When the exec-server websocket drops at the wrong time, the remote
  process can survive session recovery, but the stdin write can still fail
  back to RMCP as a transport send error. RMCP then closes the stdio MCP
  transport, so tools like `node_repl` are lost even though the
  process/session recovery path is working.
  
  This changes `process/write` to be safe to retry across exec-server
  recovery:
  
  - adds a required `writeId` to `process/write`
  - retries remote `Session::write` with the same `writeId` after
  reconnect
  - remembers accepted write ids per process so duplicate retries return
  `Accepted` without writing the same bytes to child stdin again
  - covers both the client retry path and server-side write id dedupe with
  tests
  
  In simple terms:
  
  ```text
  before:
  write to MCP stdin -> websocket closes -> write errors -> RMCP closes node_repl
  
  after:
  write to MCP stdin -> websocket closes -> reconnect -> retry same writeId
  server either writes once or recognizes it already did
  ```

• Pause active goals before TUI interrupts (#28813)

  Fixes #28104.
  
  ## Summary
  Active `/goal` turns should leave the persisted goal paused whenever the
  TUI interrupts the running turn. The bug in #28104 showed this most
  visibly through `Esc`: some interrupt paths aborted the turn without
  updating the goal status, so the goal could remain active and continue
  automatically.
  
  This change makes `ChatWidget` pause an active goal before the TUI sends
  an interrupt from the status-row path, the pending-steer path, `Ctrl+C`,
  or a request-user-input overlay. The modal overlay now reports whether a
  key will interrupt the turn, which keeps modal `Esc` and `Ctrl+C`
  behavior aligned with the normal interrupt paths.
  
  ## Manual Testing
  Built the local CLI with `just codex --help`, then launched the local
  TUI with goals enabled. Started an active `/goal` turn and interrupted
  it with `Esc`, then resumed and repeated with `Ctrl+C`; both paths
  showed `Goal paused`, the interrupted-conversation message, and the
  `Goal paused (/goal resume)` footer. I also stopped the background
  terminal and exited the TUI cleanly after the run.
  
  I did not find a reliable standalone manual path to force the
  request-user-input overlay case, so that path is covered by the focused
  automated test.

• Avoid sandbox helper in apply_patch approval tests (#28915)

  ## Summary
  This keeps the apply_patch approval tests focused on approval behavior
  instead of macOS sandboxed filesystem helper startup.
  
  The changed cases still force patch approval with `UnlessTrusted`, but
  use `DangerFullAccess` after approval so the patch write is direct and

• [codex] add rollout token budget configuration (varlength 1/N) (#28746)

  ## What
  
  This PR defines the structured configuration contract for shared rollout
  token budgets (across ALL agent threads under 1 rollout).
  
  ```toml
  [features.rollout_budget]
  enabled = true
  limit_tokens = 100000
  reminder_interval_tokens = 10000
  sampling_token_weight = 1.0
  prefill_token_weight = 0.1
  ```
  
  The reminder interval defaults to 10% of the rollout limit. Sampling and
  prefill weights default to `1.0`.
  
  ## Scope
  
  This PR only defines and validates configuration. It does not track
  usage, inject reminders, or stop a rollout. Accounting and reminders are
  implemented in the stacked follow-up #28494.
  
  The existing `token_budget` feature remains unchanged. `rollout_budget`
  has its own feature key and configuration type.
  
  ## Tests
  
  The config test verifies that the structured fields resolve into
  `RolloutBudgetConfig` and do not enable the existing `token_budget`
  feature.
  
  Local checks:
  
  - `just write-config-schema`
  - `just test -p codex-core load_config_resolves_rollout_budget`
  - `cargo check -p codex-thread-manager-sample`

• [codex] Pass plugin namespace into skill loading (#28608)

  ## What changed
  
  - retain the parsed plugin manifest namespace on loaded plugins
  - carry that namespace through `PluginSkillRoot` and `SkillRoot`
  - use the provided namespace when qualifying plugin skill names
  - include the namespace in the skills cache key
  
  ## Why
  
  Plugin loading has already parsed `plugin.json`, but skill parsing
  currently walks every `SKILL.md` ancestor and probes/reads the manifest
  again to reconstruct the same namespace. Passing the parsed namespace
  removes those repeated filesystem calls, which are particularly costly
  on remote filesystems.
  
  Context:
  https://openai.slack.com/archives/C0ARA9GF5D4/p1781639496496439?thread_ts=1781202444.891669&cid=C0ARA9GF5D4
  
  ## Impact
  
  Plugin skill names remain unchanged. A regression test uses a
  deliberately different on-disk manifest name to verify that plugin roots
  use the provided parsed namespace.

• [codex] Split plugin and skill warmup tracing (#28605)

  ## What changed
  
  - promote plugin config loading to an info-level `plugins_for_config`
  span
  - promote skill config loading to an info-level `skills_for_config` span
  - attach stable OpenTelemetry names to both spans
  
  ## Why
  
  `session_init.plugin_skill_warmup` currently combines plugin loading and
  skill loading, which makes cold-start traces unable to identify which
  phase dominates. These child spans preserve the existing aggregate while
  making the two costs independently visible.

  ## Impact
  
  This is observability-only. It does not change plugin or skill loading

• [codex] Support plugin manifest path lists (#28790)

  ## Summary
  
  Allow plugin manifests to declare `skills` as either a single path
  string or an array of path strings in the core plugin loader.
  
  ## Why
  
  Some plugin packages need to expose skills from more than one directory.
  Before this change, `plugin.json` only accepted a single string for
  `skills`, so manifests like this were ignored as an invalid `skills`
  shape:
  
  ```json
  {
    "skills": ["./skills/abc", "./skills/edk"]
  }
  ```
  
  This keeps the existing single-string form working while adding support
  for the list form. The final scope is intentionally limited to the core
  plugin manifest/load path for `skills`; `apps`, file-backed
  `mcpServers`, and the bundled plugin-creator assets are unchanged in
  this PR.
  
  ## What changed
  
  - Parse `skills` as either a string or an array of strings in
  `plugin.json`.
  - Store resolved skill paths as a list in `PluginManifestPaths`.
  - Load manifest-declared skill roots in addition to the default
  `./skills` root.
  - Deduplicate exact duplicate skill roots before loading.
  - Rely on existing skill-loader dedupe by canonical `SKILL.md` path for
  overlapping roots such as `./skills` plus `./skills/abc`.
  - Update plugin manifest tests to cover:
    - single string `skills`
    - list of string `skills`
    - duplicate skill roots
    - `./skills` as a manifest path
    - explicit child roots like `./skills/abc` and `./skills/edk`
    - overlapping-root dedupe

• Expose selecte namespaces as direct model tools (#28825)

  ## Why
  
  Som tools, such as history and notes, must remain top-level when MCP
  deferral is enabled while staying unavailable through code-mode `exec`.
  
  ## What changed
  
  - Added `features.code_mode.direct_only_tool_namespaces`.
  - Classified matching MCP tools as `DirectModelOnly`.
  - Kept those tools top-level in `code_mode_only`.
  - Excluded them from `tool_search` deferral and the nested `exec`
  surface.
  - Updated the generated config schema.

  remote exec-server connection
  - refresh the signed URL after disconnects and retry once when a
  handshake returns `401 Unauthorized`
  - allow `EnvironmentManager` consumers to register remote environments
  backed by the URL provider
  
  ## Tests
  
  - `just test -p codex-exec-server -E
  'test(remote_websocket_client_refreshes_url_after_unauthorized_handshake)
  | test(remote_websocket_client_refreshes_url_after_disconnect)'` — 2

• [codex] Support assistant realtime append text (#28836)

  ## Why
  
  Frontend realtime voice continuity needs to replay a tiny
  previous-session overlap as actual conversation items, including
  assistant text. The app-server `thread/realtime/appendText` API already
  carries a role through to the Rust realtime websocket layer, but the
  shared role enum only accepted `user` and `developer`.
  
  ## What Changed
  
  - Added `assistant` to `ConversationTextRole` and regenerated the
  app-server schema/type fixtures.
  - Added `output_text` as a realtime conversation content type.
  - Updated realtime websocket item creation so assistant appendText emits
  `content: [{ type: "output_text", text }]`, while user and developer
  continue to emit `input_text`.
  - Updated app-server docs and tests to cover assistant appendText
  alongside the existing developer role behavior.
  
  ## Validation
  
  - `just write-app-server-schema`
  - `just fmt` (first sandboxed attempt failed because `uv` could not
  access `~/.cache/uv`; reran with filesystem access and passed)
  - `just test -p codex-api` passed: 126/126
  - `just test -p codex-app-server-protocol` passed: 239/239, including
  generated JSON/TypeScript fixture checks
  - `just test -p codex-app-server` was started locally but stopped per
  request after unrelated local sandbox/Seatbelt failures (`sandbox-exec:
  sandbox_apply: Operation not permitted`) and one missing local `codex`
  binary failure; CI should be faster and more authoritative for the full
  suite.

• [codex] control automatic realtime handoff delivery (#27986)

  ## What
  
  Built on the realtime speech-control plumbing merged in #27917.
  
  - Add optional `codexResponseHandoffPrefix` to `thread/realtime/start`.
  - Apply that prefix only to automatic V1 commentary sent through
  `conversation.handoff.append`; final answers remain unprefixed.
  - Add opt-in `clientManagedHandoffs`. When true, core suppresses
  automatic response handoffs and completion output so delivery is
  controlled by explicit client append APIs.
  - Preserve existing automatic behavior by default.
  `codexResponsesAsItems: true` continues to select item routing when
  client-managed mode is disabled.
  
  ## Why
  
  Voice clients need two delivery policies: automatic background context
  with silent commentary instructions and fully client-owned handoffs.
  Phase-aware prefixing keeps routine commentary silent without
  suppressing the final answer, while client-managed mode lets an app
  decide exactly which updates to append.
  
  ## Validation
  
  - `just fmt`
  - `cargo test -p codex-app-server-protocol
  serialize_thread_realtime_start`
  - `RUST_MIN_STACK=16777216 cargo test -p codex-core --test all
  conversation_handoff_persists_across_item_done_until_turn_complete`
  - `RUST_MIN_STACK=16777216 cargo test -p codex-app-server --test all

  - `RUST_MIN_STACK=16777216 cargo test -p codex-app-server --test all
  webrtc_v1_final_automatic_handoff_omits_silent_prefix`
  - `cargo build -p codex-cli --bin codex`
  - Local Codex Apps compatibility check: 43 focused webview tests passed,
  and a live voice session routed through the source-built app-server.
  
  The explicit `RUST_MIN_STACK` avoids a macOS Tokio test-worker stack
  overflow seen with the default test environment.

• [codex] Use unique IDs for realtime-routed turns (#28826)

  ## Why
  
  A durable realtime voice orchestrator can reconnect and resume through
  multiple fresh `Session` instances. Realtime handoffs were using the
  Session-local `auto-compact-N` counter as their turn identity, but that
  counter restarts at zero for every resumed Session. The durable thread
  could therefore accumulate duplicate turn IDs, violating the uniqueness
  assumptions made by app-server and web clients. In Codex Apps, a new
  delegated response stream could be attached to an older turn with the
  same ID, placing live output higher in history and putting turn-scoped
  actions at risk.
  
  Persisted rollout and reconstructed model-context order were already
  correct because raw response items remain append-only and chronological.
  This change restores unique identity for reconstructed and live turn
  surfaces.
  
  ## What changed
  
  - Generate a UUIDv7 specifically for each realtime-routed delegation.
  - Leave the existing `auto-compact-N` identity path unchanged for actual
  internal auto-compaction turns.
  - Extend the inbound realtime handoff integration test to require a UUID
  turn ID from `turn/started`.
  
  ## Verification
  
  - `just test -p codex-core inbound_handoff_request_starts_turn`
  - `just fix -p codex-core`
  - `just fmt`

• [codex] Add optional IDs to response items (#28812)

  ## Why
  
  `ResponseItem` variants do not have a consistent internal ID shape: some
  variants carry required IDs, some carry optional IDs, and some cannot
  represent an ID at all. The existing fields also use inconsistent serde,
  TypeScript, and JSON-schema annotations. A single enum-level access path
  is needed before history recording can assign and retain IDs.
  
  This PR establishes that internal model only. It intentionally does not
  generate or serialize IDs; allocation and wire persistence are isolated
  in the stacked follow-up.
  
  ## What changed
  
  - Give every concrete `ResponseItem` variant an `Option<String>` ID
  field.
  - Apply the same internal-only annotations to every ID field:
  `#[serde(default, skip_serializing)]`, `#[ts(skip)]`, and
  `#[schemars(skip)]`.
  - Add `ResponseItem::id()` and `ResponseItem::set_id()` as the shared
  accessors.
  - Preserve IDs when history items are rewritten for truncation.
  - Adapt consumers that previously assumed reasoning and image-generation
  IDs were required.
  - Regenerate app-server schemas so the hidden fields are represented
  consistently.
  
  The serde catch-all `ResponseItem::Other` remains ID-less because it
  must remain a unit variant.
  
  ## Test plan
  
  - `cargo check --tests -p codex-core -p codex-api -p codex-rollout-trace
  -p codex-image-generation-extension`
  - `just test -p codex-protocol`

• feat(exec-server): add Noise rendezvous environment (#28774)

  ## Why
  
  Codex can run a remote exec server through the Noise relay, but the
  normal
  environment-manager path could not establish an
  environment-registry-backed
  harness connection. Signed rendezvous URLs and harness authorizations
  are
  short-lived, so reconnects must fetch a fresh bundle instead of
  retaining
  stale connection credentials. A stalled registry request must also fail
  within
  the regular remote connection deadline, without exposing these
  credentials in
  debug logs.
  
  Issue: N/A (internal environment-service integration).
  
  ## What Changed
  
  - Add environment-manager configuration for a registry-backed Noise
  rendezvous
    environment.
  - Request a fresh bundle from
  `/cloud/environment/{environment_id}/connect` for every physical harness
    connection, using the existing 10-second remote connection timeout.
  - Share the Environment Registry register, connect, and validate wire
  payloads
    through `codex-exec-server` and `codex-core-api`.
  - Redact the signed rendezvous URL and harness authorization from the
  public
    connect response's `Debug` output.
  - Add focused coverage for registry bundle retrieval, stalled requests,
  and
    credential redaction.

• path-uri: decouple native path parsing (#28778)

  ## Why
  
  `PathUri::join` should not depend on the app-server compatibility
  wrapper `LegacyAppPathString` to parse native paths. Native path parsing
  belongs to the URI abstraction that it constructs.
  
  ## What
  
  Move platform-independent native path parsing into the root `PathUri`
  module. `PathUri::join` and `LegacyAppPathString` now share the
  crate-private `PathUri::from_absolute_native_path` constructor.

• exec-server: expose environment registry payloads (#28651)

  ## Why
  
  Services that proxy the exec-server environment registry endpoints need
  to deserialize and forward the same Noise registration and harness-key
  validation payloads. Those wire models currently live as private,
  serialize-only structs in `exec-server`, which forces consumers to
  duplicate the contract.
  
  ## What changed
  
  - Add owned serde models for registration and harness-key validation
  requests and responses.
  - Use those models in the existing exec-server registry client.
  - Re-export the models from `codex-exec-server` and `codex-core-api`.
  - Keep the harness authorization request free of a derived `Debug`
  implementation so it is not accidentally logged.
  
  ## Testing
  
  - Focused exec-server registration and harness-key validation tests: 2
  passed.
  - `cargo check -p codex-core-api`
  
  The full `codex-exec-server` suite compiled and ran 254 tests: 222
  passed, while 32 existing filesystem sandbox tests could not run under
  the nested macOS sandbox (`sandbox_apply: Operation not permitted`).

• [codex] Track plugin install and import telemetry failures (#28731)

  ## Summary
  - Track plugin install failures through the unified
  `codex_plugin_install_failed` event for local installs, remote install
  preflight failures, bundle failures, and remote catalog/backend
  failures.
  - Send classified `error_type` values in plugin install failure
  analytics instead of raw error strings.
  - Stop sending raw external-agent import errors in analytics while
  preserving raw failure details in app-facing import
  notifications/history.
  - Keep raw plugin/migration diagnostics in `tracing::warn!` logs.
  - Keep remote failure plugin names as the existing local placeholder
  (`unknown`) and remove the extra telemetry plugin-name override.
  - Change `ExternalAgentConfigImportParams.source` from a generated enum
  to `string | null`, with legacy `claudeCode` / `claudeCowork` inputs
  normalized to existing analytics values.

• unified-exec: preserve PathUri through exec-server (#28681)

  ## Why
  
  It should be possible for app-server to handle "foreign" OS paths in
  unified_exec working directories, allowing e.g. a Linux app-server to
  run processes on e.g. a Windows exec-server.
  
  ## What
  
  Convert the core unified_exec cwd values to use `PathUri`.
  
  Adds fallible path conversion in several places to try to minimize the
  scope of this change. The only time this change suppresses errors from
  converting `PathUri` to an `AbsolutePathBuf` is when the turn is
  configured with no sandboxing at all to allow us to make progress
  testing without sandboxing.
  
  Future changes to apply_patch and sandboxing will clean up these error
  paths.
  
  A tool's cwd is resolved from joining a model-provided workdir to the
  environment's cwd. When using `AbsolutePathBuf::join()`, an
  absolute-path workdir would overwrite the environment's cwd and we would
  resolve permissions/sandboxing against the model-provided path. This
  change extends `PathUri::join()` to also treat an absolute rhs as an
  override of the base/lhs.
  
  This also removes some coverage from the remove_env_windows tests until
  a follow-up converts foreign paths in command exec events correctly.
  
  ## Breaking Changes
  
  When using `AbsolutePathBuf::join()` for workdir resolution, we ended up
  resolving tilde-prefixed paths against the app-server's `$HOME`, e.g.
  `~/foo/bar` becomes `/home/anp/foo/bar`. It's difficult to do this with
  `PathUri` joining, so after offline discussion this PR no longer
  implements it.
  
  A quick check of some power users' rollouts suggests that models don't
  actually generate home-prefixed absolute working directories for their
  spawns, so this shouldn't have any real blast radius.

• Extract TUI plugin catalog rendering (#28768)

  This mechanically extracts the existing TUI plugin catalog and detail
  popup rendering from `chatwidget/plugins.rs` into a new

  plugin sharing work adds more catalog behavior.
  
  - Moves existing catalog/detail popup builders and related pure helpers
  into `plugin_catalog.rs`
  - Leaves plugin fetch/state/key handling in `plugins.rs`
  - Adds only minimal sibling-module visibility/import wiring

• feat: add run task identity primitives (#19047)

  ## Stack
  
  This is PR 1 of the simplified HAI single-run-task stack:
  
  - [#19047](https://github.com/openai/codex/pull/19047) Agent Identity
  assertion and task-registration primitives, including the shared
  run-task helper used by existing Agent Identity JWT auth.
  - [#19049](https://github.com/openai/codex/pull/19049)
  Disabled-by-default ChatGPT auth opt-in that provisions/reuses persisted
  Agent Identity runtime auth and its single run task.
  - [#19051](https://github.com/openai/codex/pull/19051) Run-scoped
  provider auth that uses one backend-owned task id for first-party
  inference and compaction requests.
  
  [#19054](https://github.com/openai/codex/pull/19054) collapsed out of
  the active stack because the simplified design no longer needs a
  separate background/control-plane task helper.
  
  ## Summary
  
  The simplified POC shape is one backend-owned task per Agent Identity
  run. This PR makes the first layer match that final shape directly
  instead of introducing task targets, caller-owned external task refs, or
  intermediate wrappers that later PRs would need to undo.
  
  What changed:
  
  - keeps the `AgentAssertion` wire payload as `agent_runtime_id`,
  `task_id`, `timestamp`, and `signature`
  - exposes `register_agent_task` as the single task-registration helper
  for both existing Agent Identity JWT auth and the ChatGPT-registration
  path added later in the stack
  - makes task registration send only the signed registration timestamp;
  the backend owns the returned opaque task id
  - removes the unused target/task-kind/external-task-ref surfaces from
  `codex-agent-identity`
  - keeps Agent Identity JWT JWKS lookup separate from agent/task
  registration URL derivation
  - updates Agent Identity JWT auth to register one run task during auth
  construction and share that task across cloned auth handles
  
  This PR intentionally does not enable ChatGPT-derived Agent Identity.
  That opt-in and config gate are added in the next PR.
  
  ## Testing

• Scope command approvals by execution environment (#28738)

  ## Why
  
  Command approval cache keys included the command and working directory,
  but not the execution environment. An approval for `/workspace` locally
  could therefore be reused for the same command and path on an executor.
  
  ## What changed
  
  - Include the selected environment ID in shell and unified-exec approval
  cache keys.
  - Carry that ID through the normal command approval request so clients
  can show which environment is being approved.
  - Expose the environment through app-server as a required nullable
  `environmentId` and show it in the inline TUI approval prompt.
  - Keep older recorded approval events compatible when the environment is
  absent.
  
  For example, `echo ok` in local `/workspace` and `echo ok` in executor
  `/workspace` now produce different approval keys and separate prompts.
  
  ## Scope
  
  This PR does not change network approvals, Guardian review actions, MCP
  elicitation, full-screen TUI rendering, or environment-ID validation.
  Remote `shell_command` execution itself remains in #28722; this PR only
  makes its approval key environment-aware.

• [codex] Repair invalid skill frontmatter scalars (#28628)

  ## Why
  
  The community marketplace audit found many skill frontmatter parse
  failures where values were intended as prose, but were not valid YAML.
  Common examples include unquoted scalar values with `: `, such as
  `description: Build for AWS: ECS` or `argument-hint: <duration: e.g.
  7d>`, and flow-looking values such as `tags: [next,@supabase/ssr]`.
  
  `serde_yaml` does not expose a permissive mode for this. The parser
  fails before unknown frontmatter fields can be ignored, so a
  compatibility repair has to happen before retrying YAML parsing.
  
  ## What changed
  
  Skill frontmatter loading still uses `serde_yaml` as the primary parser.
  If that parse fails, the loader performs a line-oriented repair of
  scalar frontmatter field values, then retries parsing.
  
  The fallback now:
  
  - applies to any frontmatter mapping field, not just `description` /
  `short-description`
  - quotes unquoted scalar values that contain a YAML colon separator such
  as `: `
  - quotes invalid flow-looking scalar values that start with `[`, `{`,
  `@`, or backtick
  - preserves already quoted values
  - skips `|` / `>` block scalar bodies so multiline descriptions are not
  rewritten
  - returns the original YAML error if the repaired frontmatter still
  cannot parse
  
  ## Examples
  
  This previously failed because the second `: ` was parsed as YAML
  structure:
  
  ```yaml
  description: AWS deployment patterns: ECS Fargate, Lambda, and S3
  ```
  
  The fallback now parses it as if it had been written explicitly as:
  
  ```yaml
  description: 'AWS deployment patterns: ECS Fargate, Lambda, and S3'
  ```
  
  The same repair now applies to ignored frontmatter fields that still
  need to be valid YAML for the parser to get through the document:
  
  ```yaml
  argument-hint: <duration: e.g. 7d, 2w>
  tags: [next,@supabase/ssr]
  ```
  
  Valid YAML multiline descriptions continue to work through normal
  parsing without repair:
  
  ```yaml
  description: |-
    Build for AWS: ECS
    and Lambda
  ```
  
  ## Validation
  
  - Added loader coverage for unquoted `description` values containing `:
  `.
  - Added loader coverage for unquoted `metadata.short-description` values
  containing `: ` and an apostrophe.
  - Added loader coverage for unrecognized frontmatter fields that need
  quoting, including `argument-hint` and `tags`.
  - Added block-scalar coverage to ensure multiline description bodies are
  preserved while other fields are repaired.

• Run fs helper through Windows sandbox wrapper (#28359)

  ## Why
  
  This is the final PR in the Windows fs-helper sandbox stack and contains
  the actual bug fix.
  
  The exec-server filesystem helper is a direct-spawn path: it asks
  `SandboxManager` for a `SandboxExecRequest`, then launches the returned
  argv itself. That works on macOS and Linux because the transformed argv
  is already a self-contained sandbox wrapper. On Windows, the transformed
  request carried `WindowsRestrictedToken` metadata, but the direct-spawn
  fs-helper runner still launched the helper argv directly.
  
  That means Windows filesystem built-ins backed by the fs-helper could
  run with the parent Codex process permissions instead of the configured
  Windows sandbox. This PR makes the direct-spawn transform produce a
  self-contained Windows wrapper argv before fs-helper launches it.
  
  ## What Changed
  
  - Added `SandboxManager::transform_for_direct_spawn()` for callers that
  launch the returned argv themselves.
  - Wrapped Windows restricted-token direct-spawn requests with `codex.exe
  --run-as-windows-sandbox` and then marked the outer request as
  unsandboxed, matching the macOS/Linux wrapper argv shape.
  - Updated `exec-server/src/fs_sandbox.rs` to use the direct-spawn
  transform for fs-helper launches.
  - Materialized the inner `codex.exe --codex-run-as-fs-helper` executable
  into `.sandbox-bin` so the sandboxed user can run it.
  - Carried runtime workspace roots through `FileSystemSandboxContext` as
  `PathUri` values so `:workspace_roots` policies resolve correctly
  without sending native client paths over exec-server JSON.
  - Preserved wrapper setup identity environment needed by Windows sandbox
  setup without changing the serialized inner helper environment.
  
  ## Verification
  
  - `just bazel-lock-update`
  - `just bazel-lock-check`
  - `just test -p codex-sandboxing transform_for_direct_spawn_windows`
  - `just test -p codex-exec-server fs_sandbox::tests`
  - `just fix -p codex-windows-sandbox -p codex-sandboxing -p
  codex-exec-server -p codex-core -p codex-file-system`
  
  Local note: `just fmt` completed Rust formatting, but this workstation
  still fails the non-Rust formatter phases because uv cannot open its
  cache and the local buildifier/dotslash path is missing.

• [ez][codex-rs] Support apps._default.default_tools_approval_mode (#27965)

  [from codex]
  
  ## Summary
  
  - add `default_tools_approval_mode` to `[apps._default]` and expose it
  through app-server v2 `config/read`
  - apply it after managed, per-tool, and per-app approval settings,
  before the built-in `auto` fallback
  - document the precedence, regenerate config/app-server schemas, and add
  unit plus end-to-end approval coverage
  
  ## Configuration
  
  ```toml
  [apps._default]
  default_tools_approval_mode = "prompt"
  ```
  
  The effective precedence is managed requirements, tool-specific
  `approval_mode`, app-specific `default_tools_approval_mode`,
  `apps._default.default_tools_approval_mode`, then `auto`.
  
  ## Test plan
  
  - `just write-config-schema`
  - `just write-app-server-schema`
  - `just write-app-server-schema --experimental`
  - `just test -p codex-core app_tool_policy`
  - `just test -p codex-core mcp_turn_metadata`
  - `just test -p codex-config`
  - `just test -p codex-app-server-protocol`
  - `just test -p codex-app-server config_read_includes_apps`
  - `just fix -p codex-config -p codex-core -p codex-app-server-protocol
  -p codex-app-server`
  - `just fmt`

• Replace SkillsManager with SkillsService (#28705)

  ## Why
  
  Host skill discovery was still exposed as a manager even though it is a
  process-owned service shared by sessions, the app-server catalog, and
  file-watcher invalidation. The skills extension also consumed an ad hoc
  loaded-skills wrapper instead of a named immutable snapshot.
  
  ## What changed
  
  - replace `SkillsManager` with concrete `SkillsService`
  - make the service cache and return immutable `HostSkillsSnapshot`
  values
  - migrate the skills extension host provider to the snapshot boundary
  - migrate app-server catalog, watcher, and invalidation paths to the
  service
  
  This keeps the service limited to host discovery, caching, roots, and
  invalidation. Catalog rendering and invocation remain extension
  responsibilities for the next stacked change.

• app-server: keep the model cache warm (#28699)

  ## Why
  
  The app server is long-lived, but its shared model cache otherwise
  refreshes only when a caller needs it. Once the five-minute cache
  expires, starting a thread or calling `model/list` can wait for
  `/models` on the request path.
  
  Refresh the cache in the background before it expires so foreground
  callers normally use fresh local state.
  
  ## What changed
  
  - Start an app-server worker that refreshes models immediately and then
  every three minutes using the existing models-manager API.
  - Hold only a weak reference to the models manager between refreshes, so
  the worker does not extend its lifetime.
  - Stop scheduling refreshes when the app-server lifecycle handle is shut
  down or dropped. A refresh already in progress is allowed to finish.
  - Adjust affected app-server test fixtures to distinguish the background
  `/models` probe from the connection they are testing.
  
  The existing models-manager cache, refresh strategies, auth handling,
  ETag behavior, and concurrency semantics are unchanged.
  
  ## Testing
  
  -
  `models_refresh_worker::tests::refreshes_immediately_periodically_and_stops_when_dropped`
  -
  `suite::v2::remote_control::listen_off_honors_persisted_remote_control_enable`

• Add join key for MAv2 inter-agent messages (#28561)

  ## Summary
  This keeps inter-agent communication on the existing raw response item
  path and adds a join key for MAv2 tool calls.
  
  MAv2 `spawn_agent`, `send_message`, and `followup_task` now stamp the
  originating tool call id into `ResponseItemMetadata.source_call_id` on
  the raw `ResponseItem::AgentMessage`. App-server clients can join that
  raw item back to the existing tool/activity event by call id, while
  using the raw agent message's existing sender, receiver, and content
  fields.
  
  No new app-server `ThreadItem` or notification type is added.
  
  ## Tests
  - `just fmt`
  - `just write-app-server-schema`
  - `just test -p codex-protocol`
  - `just test -p codex-app-server-protocol`
  - `just test -p codex-core
  multi_agent_v2_spawn_returns_path_and_send_message_accepts_relative_path`
  - `just test -p codex-core
  multi_agent_v2_followup_task_completion_notifies_parent_on_every_turn`
  - `just fix -p codex-protocol`
  - `just fix -p codex-app-server-protocol`
  - `just fix -p codex-core`

• Back off registry retries during exec recovery (#28546)

  ## Why
  
  PR #28512 retries a failed session recovery every 100 ms. Every Noise
  recovery attempt first asks the environment registry for a fresh
  connection bundle, even when the eventual failure comes from the
  WebSocket or initialize handshake. During an outage, that could make
  each disconnected client call the registry about 250 times during the
  25-second recovery window.
  
  ## What changes
  
  All retryable Noise recovery failures now use a separate backoff
  schedule:
  
  ```text
  base:    500 ms -> 1 s -> 2 s -> 4 s -> 5 s maximum
  actual:  500-750 ms, 1-1.5 s, 2-3 s, 4-6 s, 5-7.5 s
  ```
  
  The extra 0-50% is deterministic per-session jitter so disconnected
  clients do not retry together. Direct WebSocket recovery keeps the
  existing 100 ms retry because it does not re-enter the registry.
