• app-server: propagate nested experimental gating for AskForApproval::Reject (#14191)

  ## Summary
  This change makes `AskForApproval::Reject` gate correctly anywhere it
  appears inside otherwise-stable app-server protocol types.
  
  Previously, experimental gating for `approval_policy: Reject` was
  handled with request-specific logic in `ClientRequest` detection. That
  covered a few request params types, but it did not generalize to other
  nested uses such as `ProfileV2`, `Config`, `ConfigReadResponse`, or
  `ConfigRequirements`.
  
  This PR replaces that ad hoc handling with a generic nested experimental
  propagation mechanism.
  
  ## Testing
  
  seeing this when run app-server-test-client without experimental api
  enabled:
  ```
   initialize response: InitializeResponse { user_agent: "codex-toy-app-server/0.0.0 (Mac OS 26.3.1; arm64) vscode/2.4.36 (codex-toy-app-server; 0.0.0)" }

• Implemented thread-level atomic elicitation counter for stopwatch pausing (#12296)

  ### Purpose
  While trying to build out CLI-Tools for the agent to use under skills we
  have found that those tools sometimes need to invoke a user elicitation.
  These elicitations are handled out of band of the codex app-server but
  need to indicate to the exec manager that the command running is not
  going to progress on the usual timeout horizon.
  
  ### Example
  Model calls universal exec:
  `$ download-credit-card-history --start-date 2026-01-19 --end-date
  2026-02-19 > credit_history.jsonl`
  
  download-cred-card-history might hit a hosted/preauthenticated service
  to fetch data. That service might decide that the request requires an
  end user approval the access to the personal data. It should be able to
  signal to the running thread that the command in question is blocked on
  user elicitation. In that case we want the exec to continue, but the
  timeout to not expire on the tool call, essentially freezing time until
  the user approves or rejects the command at which point the tool would
  signal the app-server to decrement the outstanding elicitation count.
  Now timeouts would proceed as normal.
  
  ### What's Added
  
  - New v2 RPC methods:
      - thread/increment_elicitation
      - thread/decrement_elicitation
  - Protocol updates in:
      - codex-rs/app-server-protocol/src/protocol/common.rs
      - codex-rs/app-server-protocol/src/protocol/v2.rs
  - App-server handlers wired in:
      - codex-rs/app-server/src/codex_message_processor.rs
  
  ### Behavior
  
  - Counter starts at 0 per thread.
  - increment atomically increases the counter.
  - decrement atomically decreases the counter; decrement at 0 returns
  invalid request.
  - Transition rules:
  - 0 -> 1: broadcast pause state, pausing all active stopwatches
  immediately.
      - \>0 -> >0: remain paused.
      - 1 -> 0: broadcast unpause state, resuming stopwatches.
  - Core thread/session logic:
      - codex-rs/core/src/codex_thread.rs
      - codex-rs/core/src/codex.rs
      - codex-rs/core/src/mcp_connection_manager.rs
  
  ### Exec-server stopwatch integration
  
  - Added centralized stopwatch tracking/controller:
      - codex-rs/exec-server/src/posix/stopwatch_controller.rs
  - Hooked pause/unpause broadcast handling + stopwatch registration:
      - codex-rs/exec-server/src/posix/mcp.rs
      - codex-rs/exec-server/src/posix/stopwatch.rs
      - codex-rs/exec-server/src/posix.rs

• start of hooks engine (#13276)

  (Experimental)
  
  This PR adds a first MVP for hooks, with SessionStart and Stop
  
  The core design is:
  
  - hooks live in a dedicated engine under codex-rs/hooks
  - each hook type has its own event-specific file
  - hook execution is synchronous and blocks normal turn progression while
  running
  - matching hooks run in parallel, then their results are aggregated into
  a normalized HookRunSummary
  
  On the AppServer side, hooks are exposed as operational metadata rather
  than transcript-native items:
  
  - new live notifications: hook/started, hook/completed
  - persisted/replayed hook results live on Turn.hookRuns
  - we intentionally did not add hook-specific ThreadItem variants
  
  Hooks messages are not persisted, they remain ephemeral. The context
  changes they add are (they get appended to the user's prompt)

• Stabilize protocol schema fixture generation (#13886)

  ## What changed
  - TypeScript schema fixture generation now goes through in-memory tree
  helpers rather than a heavier on-disk generation path.
  - The comparison logic normalizes generated banner and path differences
  that are not semantically relevant to the exported schema.
  - TypeScript and JSON fixture coverage are split into separate tests,
  and the expensive schema-export tests are serialized in `nextest`.
  
  ## Why this fixes the flake
  - The original fixture coverage mixed several heavy codegen paths into
  one monolithic test and then compared generated output that included
  incidental banner/path differences.
  - On Windows CI, that combination created both runtime pressure and
  output variance unrelated to the schema shapes we actually care about.
  - Splitting the coverage isolates failures by format, in-memory
  generation reduces filesystem churn, normalization strips generator
  noise, and serializing the heavy tests removes parallel resource
  contention.
  
  ## Scope
  - Production helper change plus test changes.

• Add request permissions tool (#13092)

  Adds a built-in `request_permissions` tool and wires it through the
  Codex core, protocol, and app-server layers so a running turn can ask
  the client for additional permissions instead of relying on a static
  session policy.
  
  The new flow emits a `RequestPermissions` event from core, tracks the
  pending request by call ID, forwards it through app-server v2 as an
  `item/permissions/requestApproval` request, and resumes the tool call
  once the client returns an approved subset of the requested permission
  profile.

• app-server: include experimental skill metadata in exec approval requests (#13929)

  ## Summary
  
  This change surfaces skill metadata on command approval requests so
  app-server clients can tell when an approval came from a skill script
  and identify the originating `SKILL.md`.
  
  - add `skill_metadata` to exec approval events in the shared protocol
  - thread skill metadata through core shell escalation and delegated
  approval handling for skill-triggered approvals
  - expose the field in app-server v2 as experimental `skillMetadata`
  - regenerate the JSON/TypeScript schemas and cover the new field in
  protocol, transport, core, and TUI tests
  
  ## Why
  
  Skill-triggered approvals already carry skill context inside core, but
  app-server clients could not see which skill caused the prompt. Sending
  the skill metadata with the approval request makes it possible for
  clients to present better approval UX and connect the prompt back to the
  relevant skill definition.

• Add guardian approval MVP (#13692)

  ## Summary
  - add the guardian reviewer flow for `on-request` approvals in command,
  patch, sandbox-retry, and managed-network approval paths
  - keep guardian behind `features.guardian_approval` instead of exposing
  a public `approval_policy = guardian` mode
  - route ordinary `OnRequest` approvals to the guardian subagent when the
  feature is enabled, without changing the public approval-mode surface
  
  ## Public model
  - public approval modes stay unchanged
  - guardian is enabled via `features.guardian_approval`
  - when that feature is on, `approval_policy = on-request` keeps the same
  approval boundaries but sends those approval requests to the guardian
  reviewer instead of the user
  - `/experimental` only persists the feature flag; it does not rewrite
  `approval_policy`
  - CLI and app-server no longer expose a separate `guardian` approval
  mode in this PR
  
  ## Guardian reviewer
  - the reviewer runs as a normal subagent and reuses the existing
  subagent/thread machinery
  - it is locked to a read-only sandbox and `approval_policy = never`
  - it does not inherit user/project exec-policy rules
  - it prefers `gpt-5.4` when the current provider exposes it, otherwise
  falls back to the parent turn's active model
  - it fail-closes on timeout, startup failure, malformed output, or any
  other review error
  - it currently auto-approves only when `risk_score < 80`
  
  ## Review context and policy
  - guardian mirrors `OnRequest` approval semantics rather than
  introducing a separate approval policy
  - explicit `require_escalated` requests follow the same approval surface
  as `OnRequest`; the difference is only who reviews them
  - managed-network allowlist misses that enter the approval flow are also
  reviewed by guardian
  - the review prompt includes bounded recent transcript history plus
  recent tool call/result evidence
  - transcript entries and planned-action strings are truncated with
  explicit `<guardian_truncated ... />` markers so large payloads stay
  bounded
  - apply-patch reviews include the full patch content (without
  duplicating the structured `changes` payload)
  - the guardian request layout is snapshot-tested using the same
  model-visible Responses request formatter used elsewhere in core
  
  ## Guardian network behavior
  - the guardian subagent inherits the parent session's managed-network
  allowlist when one exists, so it can use the same approved network
  surface while reviewing
  - exact session-scoped network approvals are copied into the guardian
  session with protocol/port scope preserved
  - those copied approvals are now seeded before the guardian's first turn
  is submitted, so inherited approvals are available during any immediate
  review-time checks
  
  ## Out of scope / follow-ups
  - the sandbox-permission validation split was pulled into a separate PR
  and is not part of this diff
  - a future follow-up can enable `serde_json` preserve-order in
  `codex-core` and then simplify the guardian action rendering further

• app-server: require absolute cwd for windowsSandbox/setupStart (#13833)

  ## Summary
  - require windowsSandbox/setupStart.cwd to be an AbsolutePathBuf
  - reject relative cwd values at request parsing instead of normalizing
  them later in the setup flow
  - add RPC-layer coverage for relative cwd rejection and update the
  checked-in protocol schemas/docs
  
  ## Why
  windowsSandbox/setupStart was carrying the client-provided cwd as a raw
  PathBuf for command_cwd while config derivation normalized the same
  value into an absolute policy_cwd.
  
  That left room for relative-path ambiguity in the setup path, especially
  for inputs like cwd: "repo". Making the RPC accept only absolute paths
  removes that split entirely: the handler now receives one
  already-validated absolute path and uses it for both config derivation
  and setup.
  
  This keeps the trust model unchanged. Trusted clients could already
  choose the session cwd; this change is only about making the setup RPC
  reject relative paths so command_cwd and policy_cwd cannot diverge.
  
  ## Testing
  - cargo test -p codex-app-server windows_sandbox_setup (run locally by
  user)
  - cargo test -p codex-app-server-protocol windows_sandbox (run locally
  by user)

• feat(app-server-protocol): address naming conflicts in json schema exporter (#13819)

  This fixes a schema export bug where two different `WebSearchAction`
  types were getting merged under the same name in the app-server v2 JSON
  schema bundle.
  
  The problem was that v2 thread items use the app-server API's
  `WebSearchAction` with camelCase variants like `openPage`, while
  `ThreadResumeParams.history` and
  `RawResponseItemCompletedNotification.item` pull in the upstream
  `ResponseItem` graph, which uses the Responses API snake_case shape like
  `open_page`. During bundle generation we were flattening nested
  definitions into the v2 namespace by plain name, so the later definition
  could silently overwrite the earlier one.
  
  That meant clients generating code from the bundled schema could end up
  with the wrong `WebSearchAction` definition for v2 thread history. In
  practice this shows up on web search items reconstructed from rollout
  files with persisted extended history.
  
  This change does two things:
  - Gives the upstream Responses API schema a distinct JSON schema name:
  `ResponsesApiWebSearchAction`
  - Makes namespace-level schema definition collisions fail loudly instead
  of silently overwriting

• fix: accept two macOS automation input shapes for approval payload compatibility (#13683)

  ## Summary
  This PR:
  1. fixes a deserialization mismatch for macOS automation permissions in
  approval payloads by making core parsing accept both supported wire
  shapes for bundle IDs.
  2. added `#[serde(default)]` to `MacOsSeatbeltProfileExtensions` so
  omitted fields deserialize to secure defaults.
  
  
  ## Why this change is needed
  `MacOsAutomationPermission` uses `#[serde(try_from =
  "MacOsAutomationPermissionDe")]`, so deserialization is controlled by
  `MacOsAutomationPermissionDe`. After we aligned v2
  `additionalPermissions.macos.automations` to the core shape, approval
  payloads started including `{ "bundle_ids": [...] }` in some paths.
  `MacOsAutomationPermissionDe` previously accepted only `"none" | "all"`
  or a plain array, so object-shaped bundle IDs failed with `data did not
  match any variant of untagged enum MacOsAutomationPermissionDe`. This
  change restores compatibility by accepting both forms while preserving
  existing normalization behavior (trim values and map empty bundle lists
  to `None`).

• add @plugin mentions (#13510)

  ## Note-- added plugin mentions via @, but that conflicts with file
  mentions
  
  depends and builds upon #13433.
  
  - introduces explicit `@plugin` mentions. this injects the plugin's mcp
  servers, app names, and skill name format into turn context as a dev
  message.
  - we do not yet have UI for these mentions, so we currently parse raw
  text (as opposed to skills and apps which have UI chips, autocomplete,
  etc.) this depends on a `plugins/list` app-server endpoint we can feed
  the UI with, which is upcoming
  - also annotate mcp and app tool descriptions with the plugin(s) they
  come from. this gives the model a first class way of understanding what
  tools come from which plugins, which will help implicit invocation.
  
  ### Tests
  Added and updated tests, unit and integration. Also confirmed locally a
  raw `@plugin` injects the dev message, and the model knows about its
  apps, mcps, and skills.

• feat(app-server): support mcp elicitations in v2 api (#13425)

  This adds a first-class server request for MCP server elicitations:
  `mcpServer/elicitation/request`.
  
  Until now, MCP elicitation requests only showed up as a raw
  `codex/event/elicitation_request` event from core. That made it hard for
  v2 clients to handle elicitations using the same request/response flow
  as other server-driven interactions (like shell and `apply_patch`
  tools).
  
  This also updates the underlying MCP elicitation request handling in
  core to pass through the full MCP request (including URL and form data)
  so we can expose it properly in app-server.
  
  ### Why not `item/mcpToolCall/elicitationRequest`?
  This is because MCP elicitations are related to MCP servers first, and
  only optionally to a specific MCP tool call.
  
  In the MCP protocol, elicitation is a server-to-client capability: the
  server sends `elicitation/create`, and the client replies with an
  elicitation result. RMCP models it that way as well.
  
  In practice an elicitation is often triggered by an MCP tool call, but
  not always.
  
  ### What changed
  - add `mcpServer/elicitation/request` to the v2 app-server API
  - translate core `codex/event/elicitation_request` events into the new
  v2 server request
  - map client responses back into `Op::ResolveElicitation` so the MCP
  server can continue
  - update app-server docs and generated protocol schema
  - add an end-to-end app-server test that covers the full round trip
  through a real RMCP elicitation flow
  - The new test exercises a realistic case where an MCP tool call
  triggers an elicitation, the app-server emits
  mcpServer/elicitation/request, the client accepts it, and the tool call
  resumes and completes successfully.
  
  ### app-server API flow
  - Client starts a thread with `thread/start`.
  - Client starts a turn with `turn/start`.
  - App-server sends `item/started` for the `mcpToolCall`.
  - While that tool call is in progress, app-server sends
  `mcpServer/elicitation/request`.
  - Client responds to that request with `{ action: "accept" | "decline" |
  "cancel" }`.
  - App-server sends `serverRequest/resolved`.
  - App-server sends `item/completed` for the mcpToolCall.
  - App-server sends `turn/completed`.
  - If the turn is interrupted while the elicitation is pending,
  app-server still sends `serverRequest/resolved` before the turn
  finishes.

• allow apps to specify cwd for sandbox setup. (#13484)

  The electron app doesn't start up the app-server in a particular
  workspace directory.
  So sandbox setup happens in the app-installed directory instead of the
  project workspace.
  
  This allows the app do specify the workspace cwd so that the sandbox
  setup actually sets up the ACLs instead of exiting fast and then having
  the first shell command be slow.

• chore: Nest skill and protocol network permissions under network.enabled (#13427)

  ## Summary
  
  Changes the permission profile shape from a bare network boolean to a
  nested object.
  
  Before:
  
  ```yaml
  permissions:
    network: true
  ```
  
  After:
  
  ```yaml
  permissions:
    network:
      enabled: true
  ```
  
  This also updates the shared Rust and app-server protocol types so
  `PermissionProfile.network` is no longer `Option<bool>`, but
  `Option<NetworkPermissions>` with `enabled: Option<bool>`.
  
  ## What Changed
  
  - Updated `PermissionProfile` in `codex-rs/protocol/src/models.rs`:
  - `pub network: Option<bool>` -> `pub network:
  Option<NetworkPermissions>`
  - Added `NetworkPermissions` with:
    - `pub enabled: Option<bool>`
  - Changed emptiness semantics so `network` is only considered empty when
  `enabled` is `None`
  - Updated skill metadata parsing to accept `permissions.network.enabled`
  - Updated core permission consumers to read
  `network.enabled.unwrap_or(false)` where a concrete boolean is needed
  - Updated app-server v2 protocol types and regenerated schema/TypeScript
  outputs
  - Updated docs to mention `additionalPermissions.network.enabled`

• config: enforce enterprise feature requirements (#13388)

  ## Why
  
  Enterprises can already constrain approvals, sandboxing, and web search
  through `requirements.toml` and MDM, but feature flags were still only
  configurable as managed defaults. That meant an enterprise could suggest
  feature values, but it could not actually pin them.
  
  This change closes that gap and makes enterprise feature requirements
  behave like the other constrained settings. The effective feature set
  now stays consistent with enterprise requirements during config load,
  when config writes are validated, and when runtime code mutates feature
  flags later in the session.
  
  It also tightens the runtime API for managed features. `ManagedFeatures`
  now follows the same constraint-oriented shape as `Constrained<T>`
  instead of exposing panic-prone mutation helpers, and production code
  can no longer construct it through an unconstrained `From<Features>`
  path.
  
  The PR also hardens the `compact_resume_fork` integration coverage on
  Windows. After the feature-management changes,
  `compact_resume_after_second_compaction_preserves_history` was
  overflowing the libtest/Tokio thread stacks on Windows, so the test now
  uses an explicit larger-stack harness as a pragmatic mitigation. That
  may not be the ideal root-cause fix, and it merits a parallel
  investigation into whether part of the async future chain should be
  boxed to reduce stack pressure instead.
  
  ## What Changed
  
  Enterprises can now pin feature values in `requirements.toml` with the
  requirements-side `features` table:
  
  ```toml
  [features]
  personality = true
  unified_exec = false
  ```
  
  Only canonical feature keys are allowed in the requirements `features`
  table; omitted keys remain unconstrained.
  
  - Added a requirements-side pinned feature map to
  `ConfigRequirementsToml`, threaded it through source-preserving
  requirements merge and normalization in `codex-config`, and made the
  TOML surface use `[features]` (while still accepting legacy
  `[feature_requirements]` for compatibility).
  - Exposed `featureRequirements` from `configRequirements/read`,
  regenerated the JSON/TypeScript schema artifacts, and updated the
  app-server README.
  - Wrapped the effective feature set in `ManagedFeatures`, backed by
  `ConstrainedWithSource<Features>`, and changed its API to mirror
  `Constrained<T>`: `can_set(...)`, `set(...) -> ConstraintResult<()>`,
  and result-returning `enable` / `disable` / `set_enabled` helpers.
  - Removed the legacy-usage and bulk-map passthroughs from
  `ManagedFeatures`; callers that need those behaviors now mutate a plain
  `Features` value and reapply it through `set(...)`, so the constrained
  wrapper remains the enforcement boundary.
  - Removed the production loophole for constructing unconstrained
  `ManagedFeatures`. Non-test code now creates it through the configured
  feature-loading path, and `impl From<Features> for ManagedFeatures` is
  restricted to `#[cfg(test)]`.
  - Rejected legacy feature aliases in enterprise feature requirements,
  and return a load error when a pinned combination cannot survive
  dependency normalization.
  - Validated config writes against enterprise feature requirements before
  persisting changes, including explicit conflicting writes and
  profile-specific feature states that normalize into invalid
  combinations.
  - Updated runtime and TUI feature-toggle paths to use the constrained
  setter API and to persist or apply the effective post-constraint value
  rather than the requested value.
  - Updated the `core_test_support` Bazel target to include the bundled
  core model-catalog fixtures in its runtime data, so helper code that
  resolves `core/models.json` through runfiles works in remote Bazel test
  environments.
  - Renamed the core config test coverage to emphasize that effective
  feature values are normalized at runtime, while conflicting persisted
  config writes are rejected.
  - Ran `compact_resume_after_second_compaction_preserves_history` inside
  an explicit 8 MiB test thread and Tokio runtime worker stack, following
  the existing larger-stack integration-test pattern, to keep the Windows
  `compact_resume_fork` test slice from aborting while a parallel
  investigation continues into whether some of the underlying async
  futures should be boxed.
  
  ## Verification
  
  - `cargo test -p codex-config`
  - `cargo test -p codex-core feature_requirements_ -- --nocapture`
  - `cargo test -p codex-core
  load_requirements_toml_produces_expected_constraints -- --nocapture`
  - `cargo test -p codex-core
  compact_resume_after_second_compaction_preserves_history -- --nocapture`
  - `cargo test -p codex-core compact_resume_fork -- --nocapture`
  - Re-ran the built `codex-core` `tests/all` binary with
  `RUST_MIN_STACK=262144` for
  `compact_resume_after_second_compaction_preserves_history` to confirm
  the explicit-stack harness fixes the deterministic low-stack repro.
  - `cargo test -p codex-core`
  - This still fails locally in unrelated integration areas that expect
  the `codex` / `test_stdio_server` binaries or hit existing `search_tool`
  wiremock mismatches.
  
  ## Docs
  
  `developers.openai.com/codex` should document the requirements-side
  `[features]` table for enterprise and MDM-managed configuration,
  including that it only accepts canonical feature keys and that
  conflicting config writes are rejected.

• Feat: Preserve network access on read-only sandbox policies (#13409)

  ## Summary
  
  `PermissionProfile.network` could not be preserved when additional or
  compiled permissions resolved to
  `SandboxPolicy::ReadOnly`, because `ReadOnly` had no network_access
  field. This change makes read-only + network
  enabled representable directly and threads that through the protocol,
  app-server v2 mirror, and permission-
    merging logic.
  
  ## What changed
  
  - Added `network_access: bool` to `SandboxPolicy::ReadOnly` in the core
  protocol and app-server v2 protocol.
  - Kept backward compatibility by defaulting the new field to false, so
  legacy read-only payloads still
      deserialize unchanged.
  - Updated `has_full_network_access()` and sandbox summaries to respect
  read-only network access.
    - Preserved PermissionProfile.network when:
        - compiling skill permission profiles into sandbox policies
        - normalizing additional permissions
        - merging additional permissions into existing sandbox policies
  - Updated the approval overlay to show network in the rendered
  permission rule when requested.
    - Regenerated app-server schema fixtures for the new v2 wire shape.

  - add the v2 `thread/metadata/update` API, including
  protocol/schema/TypeScript exports and app-server docs
  - patch stored thread `gitInfo` in sqlite without resuming the thread,
  with validation plus support for explicit `null` clears
  - repair missing sqlite thread rows from rollout data before patching,
  and make those repairs safe by inserting only when absent and updating
  only git columns so newer metadata is not clobbered
  - keep sqlite authoritative for mutable thread git metadata by
  preserving existing sqlite git fields during reconcile/backfill and only
  using rollout `SessionMeta` git fields to fill gaps
  - add regression coverage for the endpoint, repair paths, concurrent
  sqlite writes, clearing git fields, and rollout/backfill reconciliation
  - fix the login server shutdown race so cancelling before the waiter
  starts still terminates `block_until_done()` correctly
  
  ## Testing

• chore(app-server): delete v1 RPC methods and notifications (#13375)

  ## Summary
  This removes the old app-server v1 methods and notifications we no
  longer need, while keeping the small set the main codex app client still
  depends on for now.
  
  The remaining legacy surface is:
  - `initialize`
  - `getConversationSummary`
  - `getAuthStatus`
  - `gitDiffToRemote`
  - `fuzzyFileSearch`
  - `fuzzyFileSearch/sessionStart`
  - `fuzzyFileSearch/sessionUpdate`
  - `fuzzyFileSearch/sessionStop`
  
  And the raw `codex/event/*` notifications emitted from core. These
  notifications will be removed in a followup PR.
  
  ## What changed
  - removed deprecated v1 request variants from the protocol and
  app-server dispatcher
  - removed deprecated typed notifications: `authStatusChange`,
  `loginChatGptComplete`, and `sessionConfigured`
  - updated the app-server test client to use v2 flows instead of deleted
  v1 flows
  - deleted legacy-only app-server test suites and added focused coverage
  for `getConversationSummary`
  - regenerated app-server schema fixtures and updated the MCP interface
  docs to match the remaining compatibility surface
  
  ## Testing
  - `just write-app-server-schema`
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-app-server`

• feat(app-server): add tracing to all app-server APIs (#13285)

  ### Overview
  This PR adds the first piece of tracing for app-server JSON-RPC
  requests.
  
  There are two main changes:
  - JSON-RPC requests can now take an optional W3C trace context at the
  top level via a `trace` field (`traceparent` / `tracestate`).
  - app-server now creates a dedicated request span for every inbound
  JSON-RPC request in `MessageProcessor`, and uses the request-level trace
  context as the parent when present.
  
  For compatibility with existing flows, app-server still falls back to
  the TRACEPARENT env var when there is no request-level traceparent.
  
  This PR is intentionally scoped to the app-server boundary. In a
  followup, we'll actually propagate trace context through the async
  handoff into core execution spans like run_turn, which will make
  app-server traces much more useful.
  
  ### Spans
  A few details on the app-server span shape:
  - each inbound request gets its own server span
  - span/resource names are based on the JSON-RPC method (`initialize`,
  `thread/start`, `turn/start`, etc.)
  - spans record transport (stdio vs websocket), request id, connection
  id, and client name/version when available
  - `initialize` stores client metadata in session state so later requests
  on the same connection can reuse it

• [codex] include plan type in account updates (#13181)

  This change fixes a Codex app account-state sync bug where clients could
  know the user was signed in but still miss the ChatGPT subscription
  tier, which could lead to incorrect upgrade messaging for paid users.
  
  The root cause was that `account/updated` only carried `authMode` while
  plan information was available separately via `account/read` and
  rate-limit snapshots, so this update adds `planType` to
  `account/updated`, populates it consistently across login and refresh
  paths.

• app-server: Replay pending item requests on thread/resume (#12560)

  Replay pending client requests after `thread/resume` and emit resolved
  notifications when those requests clear so approval/input UI state stays
  in sync after reconnects and across subscribed clients.
  
  Affected RPCs:
  - `item/commandExecution/requestApproval`
  - `item/fileChange/requestApproval`
  - `item/tool/requestUserInput`
  
  Motivation:
  - Resumed clients need to see pending approval/input requests that were
  already outstanding before the reconnect.
  - Clients also need an explicit signal when a pending request resolves
  or is cleared so stale UI can be removed on turn start, completion, or
  interruption.
  
  Implementation notes:
  - Use pending client requests from `OutgoingMessageSender` in order to
  replay them after `thread/resume` attaches the connection, using
  original request ids.
  - Emit `serverRequest/resolved` when pending requests are answered
  or cleared by lifecycle cleanup.
  - Update the app-server protocol schema, generated TypeScript bindings,
  and README docs for the replay/resolution flow.
  
  High-level test plan:
  - Added automated coverage for replaying pending command execution and
  file change approval requests on `thread/resume`.
  - Added automated coverage for resolved notifications in command
  approval, file change approval, request_user_input, turn start, and turn
  interrupt flows.
  - Verified schema/docs updates in the relevant protocol and app-server
  tests.
  
  Manual testing:
  - Tested reconnect/resume with multiple connections.
  - Confirmed state stayed in sync between connections.

• fix: use AbsolutePathBuf for permission profile file roots (#12970)

  ## Why
  `PermissionProfile` should describe filesystem roots as absolute paths
  at the type level. Using `PathBuf` in `FileSystemPermissions` made the
  shared type too permissive and blurred together three different
  deserialization cases:
  
  - skill metadata in `agents/openai.yaml`, where relative paths should
  resolve against the skill directory
  - app-server API payloads, where callers should have to send absolute
  paths
  - local tool-call payloads for commands like `shell_command` and
  `exec_command`, where `additional_permissions.file_system` may
  legitimately be relative to the command `workdir`
  
  This change tightens the shared model without regressing the existing
  local command flow.
  
  ## What Changed
  - changed `protocol::models::FileSystemPermissions` and the app-server
  `AdditionalFileSystemPermissions` mirror to use `AbsolutePathBuf`
  - wrapped skill metadata deserialization in `AbsolutePathBufGuard`, so
  relative permission roots in `agents/openai.yaml` resolve against the
  containing skill directory
  - kept app-server/API deserialization strict, so relative
  `additionalPermissions.fileSystem.*` paths are rejected at the boundary
  - restored cwd/workdir-relative deserialization for local tool-call
  payloads by parsing `shell`, `shell_command`, and `exec_command`
  arguments under an `AbsolutePathBufGuard` rooted at the resolved command
  working directory
  - simplified runtime additional-permission normalization so it only
  canonicalizes and deduplicates absolute roots instead of trying to
  recover relative ones later
  - updated the app-server schema fixtures, `app-server/README.md`, and
  the affected transport/TUI tests to match the final behavior

• Enforce user input length cap (#12823)

  Currently there is no bound on the length of a user message submitted in
  the TUI or through the app server interface. That means users can paste
  many megabytes of text, which can lead to bad performance, hangs, and
  crashes. In extreme cases, it can lead to a [kernel
  panic](https://github.com/openai/codex/issues/12323).
  
  This PR limits the length of a user input to 2**20 (about 1M)
  characters. This value was chosen because it fills the entire context
  window on the latest models, so accepting longer inputs wouldn't make
  sense anyway.
  
  Summary
  - add a shared `MAX_USER_INPUT_TEXT_CHARS` constant in codex-protocol
  and surface it in TUI and app server code
  - block oversized submissions in the TUI submit flow and emit error
  history cells when validation fails
  - reject heavy app-server requests with JSON-RPC `-32602` and structured
  `input_too_large` data, plus document the behavior
  
  Testing
  - ran the IDE extension with this change and verified that when I
  attempt to paste a user message that's several MB long, it correctly
  reports an error instead of crashing or making my computer hot.

• feat: include available decisions in command approval requests (#12758)

  Command-approval clients currently infer which choices to show from
  side-channel fields like `networkApprovalContext`,
  `proposedExecpolicyAmendment`, and `additionalPermissions`. That makes
  the request shape harder to evolve, and it forces each client to
  replicate the server's heuristics instead of receiving the exact
  decision list for the prompt.
  
  This PR introduces a mapping between `CommandExecutionApprovalDecision`
  and `codex_protocol::protocol::ReviewDecision`:
  
  ```rust
  impl From<CoreReviewDecision> for CommandExecutionApprovalDecision {
      fn from(value: CoreReviewDecision) -> Self {
          match value {
              CoreReviewDecision::Approved => Self::Accept,
              CoreReviewDecision::ApprovedExecpolicyAmendment {
                  proposed_execpolicy_amendment,
              } => Self::AcceptWithExecpolicyAmendment {
                  execpolicy_amendment: proposed_execpolicy_amendment.into(),
              },
              CoreReviewDecision::ApprovedForSession => Self::AcceptForSession,
              CoreReviewDecision::NetworkPolicyAmendment {
                  network_policy_amendment,
              } => Self::ApplyNetworkPolicyAmendment {
                  network_policy_amendment: network_policy_amendment.into(),
              },
              CoreReviewDecision::Abort => Self::Cancel,
              CoreReviewDecision::Denied => Self::Decline,
          }
      }
  }
  ```
  
  And updates `CommandExecutionRequestApprovalParams` to have a new field:
  
  ```rust
  available_decisions: Option<Vec<CommandExecutionApprovalDecision>>
  ```
  
  when, if specified, should make it easier for clients to display an
  appropriate list of options in the UI.
  
  This makes it possible for `CoreShellActionProvider::prompt()` in
  `unix_escalation.rs` to specify the `Vec<ReviewDecision>` directly,
  adding support for `ApprovedForSession` when approving a skill script,
  which was previously missing in the TUI.
  
  Note this results in a significant change to `exec_options()` in
  `approval_overlay.rs`, as the displayed options are now derived from
  `available_decisions: &[ReviewDecision]`.
  
  ## What Changed
  
  - Add `available_decisions` to
  [`ExecApprovalRequestEvent`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/protocol/src/approvals.rs#L111-L175),
  including helpers to derive the legacy default choices when older
  senders omit the field.
  - Map `codex_protocol::protocol::ReviewDecision` to app-server
  `CommandExecutionApprovalDecision` and expose the ordered list as
  experimental `availableDecisions` in
  [`CommandExecutionRequestApprovalParams`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/app-server-protocol/src/protocol/v2.rs#L3798-L3807).
  - Thread optional `available_decisions` through the core approval path
  so Unix shell escalation can explicitly request `ApprovedForSession` for
  session-scoped approvals instead of relying on client heuristics.
  [`unix_escalation.rs`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L194-L214)
  - Update the TUI approval overlay to build its buttons from the ordered
  decision list, while preserving the legacy fallback when
  `available_decisions` is missing.
  - Update the app-server README, test client output, and generated schema
  artifacts to document and surface the new field.
  
  ## Testing
  
  - Add `approval_overlay.rs` coverage for explicit decision lists,
  including the generic `ApprovedForSession` path and network approval
  options.
  - Update `chatwidget/tests.rs` and app-server protocol tests to populate
  the new optional field and keep older event shapes working.
  
  ## Developers Docs
  
  - If we document `item/commandExecution/requestApproval` on
  [developers.openai.com/codex](https://developers.openai.com/codex), add
  experimental `availableDecisions` as the preferred source of approval
  choices and note that older servers may omit it.

• Revert "Add skill approval event/response (#12633)" (#12811)

  This reverts commit https://github.com/openai/codex/pull/12633. We no
  longer need this PR, because we favor sending normal exec command
  approval server request with `additional_permissions` of skill
  permissions instead

• Enable request_user_input in Default mode (#12735)

  ## Summary
  - allow `request_user_input` in Default collaboration mode as well as
  Plan
  - update the Default-mode instructions to prefer assumptions first and
  use `request_user_input` only when a question is unavoidable
  - update request_user_input and app-server tests to match the new
  Default-mode behavior
  - refactor collaboration-mode availability plumbing into
  `CollaborationModesConfig` for future mode-related flags
