• 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.

• 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

• check app auth in plugin/install (#13685)

  #### What
  on `plugin/install`, check if installed apps are already authed on
  chatgpt, and return list of all apps that are not. clients can use this
  list to trigger auth workflows as needed.
  
  checks are best effort based on `codex_apps` loading, much like
  `app/list`.
  
  #### Tests
  Added integration tests, tested locally.

• 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-test-client): OTEL setup for tracing (#13493)

  ### Overview
  This PR:
  - Updates `app-server-test-client` to load OTEL settings from
  `$CODEX_HOME/config.toml` and initializes its own OTEL provider.
  - Add real client root spans to app-server test client traces.
  
  This updates `codex-app-server-test-client` so its Datadog traces
  reflect the full client-driven flow instead of a set of server spans
  stitched together under a synthetic parent.
  
  Before this change, the test client generated a fake `traceparent` once
  and reused it for every JSON-RPC request. That kept the requests in one
  trace, but there was no real client span at the top, so Datadog ended up
  showing the sequence in a slightly misleading way, where all RPCs were
  anchored under `initialize`.
  
  Now the test client:
  - loads OTEL settings from the normal Codex config path, including
  `$CODEX_HOME/config.toml` and existing --config overrides
  - initializes tracing the same way other Codex binaries do when trace
  export is enabled
  - creates a real client root span for each scripted command
  - creates per-request client spans for JSON-RPC methods like
  `initialize`, `thread/start`, and `turn/start`
  - injects W3C trace context from the current client span into
  request.trace instead of reusing a fabricated carrier
  
  This gives us a cleaner trace shape in Datadog:
  - one trace URL for the whole scripted flow
  - a visible client root span
  - proper client/server parent-child relationships for each app-server
  request

• 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.

• 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 under-development original-resolution view_image support (#13050)

  ## Summary
  
  Add original-resolution support for `view_image` behind the
  under-development `view_image_original_resolution` feature flag.
  
  When the flag is enabled and the target model is `gpt-5.3-codex` or
  newer, `view_image` now preserves original PNG/JPEG/WebP bytes and sends
  `detail: "original"` to the Responses API instead of using the legacy
  resize/compress path.
  
  ## What changed
  
  - Added `view_image_original_resolution` as an under-development feature
  flag.
  - Added `ImageDetail` to the protocol models and support for serializing
  `detail: "original"` on tool-returned images.
  - Added `PromptImageMode::Original` to `codex-utils-image`.
    - Preserves original PNG/JPEG/WebP bytes.
    - Keeps legacy behavior for the resize path.
  - Updated `view_image` to:
  - use the shared `local_image_content_items_with_label_number(...)`
  helper in both code paths
    - select original-resolution mode only when:
      - the feature flag is enabled, and
      - the model slug parses as `gpt-5.3-codex` or newer
  - Kept local user image attachments on the existing resize path; this
  change is specific to `view_image`.
  - Updated history/image accounting so only `detail: "original"` images
  use the docs-based GPT-5 image cost calculation; legacy images still use
  the old fixed estimate.
  - Added JS REPL guidance, gated on the same feature flag, to prefer JPEG
  at 85% quality unless lossless is required, while still allowing other
  formats when explicitly requested.
  - Updated tests and helper code that construct
  `FunctionCallOutputContentItem::InputImage` to carry the new `detail`
  field.
  
  ## Behavior
  
  ### Feature off
  - `view_image` keeps the existing resize/re-encode behavior.
  - History estimation keeps the existing fixed-cost heuristic.
  
  ### Feature on + `gpt-5.3-codex+`
  - `view_image` sends original-resolution images with `detail:
  "original"`.
  - PNG/JPEG/WebP source bytes are preserved when possible.
  - History estimation uses the GPT-5 docs-based image-cost calculation
  for those `detail: "original"` images.

• Add thread metadata update endpoint to app server (#13280)

  ## Summary
  - 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

  (majority of this PR is generated schema jsons - actual code is +69 /
  -35 and +24 tests )
  
  - add service tier fields to the app-server protocol surfaces used by
  thread lifecycle, turn start, config, and session configured events
  - thread service tier through the app-server message processor and core
  thread config snapshots
  - allow runtime config overrides to carry service tier for app-server
  callers
  
  cleanup:
  - Removing useless "legacy" code supporting "standard" - we moved to
  None | "fast", so "standard" is not needed.

• [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.

• Support multimodal custom tool outputs (#12948)

  ## Summary
  
  This changes `custom_tool_call_output` to use the same output payload
  shape as `function_call_output`, so freeform tools can return either
  plain text or structured content items.
  
  The main goal is to let `js_repl` return image content from nested
  `view_image` calls in its own `custom_tool_call_output`, instead of
  relying on a separate injected message.
  
  ## What changed
  
  - Changed `custom_tool_call_output.output` from `string` to
  `FunctionCallOutputPayload`
  - Updated freeform tool plumbing to preserve structured output bodies
  - Updated `js_repl` to aggregate nested tool content items and attach
  them to the outer `js_repl` result
  - Removed the old `js_repl` special case that injected `view_image`
  results as a separate pending user image message
  - Updated normalization/history/truncation paths to handle multimodal
  `custom_tool_call_output`
  - Regenerated app-server protocol schema artifacts
  
  ## Behavior
  
  Direct `view_image` calls still return a `function_call_output` with
  image content.
  
  When `view_image` is called inside `js_repl`, the outer `js_repl`
  `custom_tool_call_output` now carries:
  - an `input_text` item if the JS produced text output
  - one or more `input_image` items from nested tool results
  
  So the nested image result now stays inside the `js_repl` tool output
  instead of being injected as a separate message.
  
  ## Compatibility
  
  This is intended to be backward-compatible for resumed conversations.
  
  Older histories that stored `custom_tool_call_output.output` as a plain
  string still deserialize correctly, and older histories that used the
  previous injected-image-message flow also continue to resume.
  
  Added regression coverage for resuming a pre-change rollout containing:
  - string-valued `custom_tool_call_output`
  - legacy injected image message history

• feat(app-server): thread/unsubscribe API (#10954)

  Adds a new v2 app-server API for a client to be able to unsubscribe to a
  thread:
  - New RPC method: `thread/unsubscribe`
  - New server notification: `thread/closed`
  
  Today clients can start/resume/archive threads, but there wasn’t a way
  to explicitly unload a live thread from memory without archiving it.
  With `thread/unsubscribe`, a client can indicate it is no longer
  actively working with a live Thread. If this is the only client
  subscribed to that given thread, the thread will be automatically closed
  by app-server, at which point the server will send `thread/closed` and
  `thread/status/changed` with `status: notLoaded` notifications.
  
  This gives clients a way to prevent long-running app-server processes
  from accumulating too many thread (and related) objects in memory.
  
  Closed threads will also be removed from `thread/loaded/list`.

• feat(app-server): add ThreadItem::DynamicToolCall (#12732)

  Previously, clients would call `thread/start` with dynamic_tools set,
  and when a model invokes a dynamic tool, it would just make the
  server->client `item/tool/call` request and wait for the client's
  response to complete the tool call. This works, but it doesn't have an
  `item/started` or `item/completed` event.
  
  Now we are doing this:
  - [new] emit `item/started` with `DynamicToolCall` populated with the
  call arguments
  - send an `item/tool/call` server request
  - [new] once the client responds, emit `item/completed` with
  `DynamicToolCall` populated with the response.
  
  Also, with `persistExtendedHistory: true`, dynamic tool calls are now
  reconstructable in `thread/read` and `thread/resume` as
  `ThreadItem::DynamicToolCall`.

• feat: use OAI Responses API MessagePhase type directly in App Server v2 (#12422)

  https://github.com/openai/codex/pull/10455 introduced the `phase` field,
  and then https://github.com/openai/codex/pull/12072 introduced a
  `MessagePhase` type in `v2.rs` that paralleled the `MessagePhase` type
  in `codex-rs/protocol/src/models.rs`.
  
  The app server protocol prefers `camelCase` while the Responses API uses
  `snake_case`, so this meant we had two versions of `MessagePhase` with
  different serialization rules. When the app server protocol refers to
  types from the Responses API, we use the wire format of the the
  Responses API even though it is inconsistent with the app server API.
  
  This PR deletes `MessagePhase` from `v2.rs` and consolidates on the
  Responses API version to eliminate confusion.

  We don't do this for `thread/start` and `thread/fork`.

• fix(network-proxy): add unix socket allow-all and update seatbelt rules (#11368)

  ## Summary
  Adds support for a Unix socket escape hatch so we can bypass socket
  allowlisting when explicitly enabled.
  
  ## Description
  * added a new flag, `network.dangerously_allow_all_unix_sockets` as an
  explicit escape hatch
  * In codex-network-proxy, enabling that flag now allows any absolute
  Unix socket path from x-unix-socket instead of requiring each path to be
  explicitly allowlisted. Relative paths are still rejected.
  * updated the macOS seatbelt path in core so it enforces the same Unix
  socket behavior:
    * allowlisted sockets generate explicit network* subpath rules
    * allow-all generates a broad network* (subpath "/") rule

• feat: add Reject approval policy with granular prompt rejection controls (#12087)

  ## Why
  
  We need a way to auto-reject specific approval prompt categories without
  switching all approvals off.
  
  The goal is to let users independently control:
  - sandbox escalation approvals,
  - execpolicy `prompt` rule approvals,
  - MCP elicitation prompts.
  
  ## What changed
  
  - Added a new primary approval mode in `protocol/src/protocol.rs`:
  
  ```rust
  pub enum AskForApproval {
      // ...
      Reject(RejectConfig),
      // ...
  }
  
  pub struct RejectConfig {
      pub sandbox_approval: bool,
      pub rules: bool,
      pub mcp_elicitations: bool,
  }
  ```
  
  - Wired `RejectConfig` semantics through approval paths in `core`:
    - `core/src/exec_policy.rs`
      - rejects rule-driven prompts when `rules = true`
      - rejects sandbox/escalation prompts when `sandbox_approval = true`
  - preserves rule priority when both rule and sandbox prompt conditions
  are present
    - `core/src/tools/sandboxing.rs`
  - applies `sandbox_approval` to default exec approval decisions and
  sandbox-failure retry gating
    - `core/src/safety.rs`
  - keeps `Reject { all false }` behavior aligned with `OnRequest` for
  patch safety
      - rejects out-of-root patch approvals when `sandbox_approval = true`
    - `core/src/mcp_connection_manager.rs`
      - auto-declines MCP elicitations when `mcp_elicitations = true`
  
  - Ensured approval policy used by MCP elicitation flow stays in sync
  with constrained session policy updates.
  
  - Updated app-server v2 conversions and generated schema/TypeScript
  artifacts for the new `Reject` shape.
  
  ## Verification
  
  Added focused unit coverage for the new behavior in:
  - `core/src/exec_policy.rs`
  - `core/src/tools/sandboxing.rs`
  - `core/src/mcp_connection_manager.rs`
  - `core/src/safety.rs`
  - `core/src/tools/runtimes/apply_patch.rs`
  
  Key cases covered include rule-vs-sandbox prompt precedence, MCP
  auto-decline behavior, and patch/sandbox retry behavior under
  `RejectConfig`.

• app-server: expose loaded thread status via read/list and notifications (#11786)

  Motivation
  - Today, a newly connected client has no direct way to determine the
  current runtime status of threads from read/list responses alone.
  - This forces clients to infer state from transient events, which can
  lead to stale or inconsistent UI when reconnecting or attaching late.
  
  Changes
  - Add `status` to `thread/read` responses.
  - Add `statuses` to `thread/list` responses.
  - Emit `thread/status/changed` notifications with `threadId` and the new
  status.
  - Track runtime status for all loaded threads and default unknown
  threads to `idle`.
  - Update protocol/docs/tests/schema fixtures for the revised API.
  
  Testing
  - Validated protocol API changes with automated protocol tests and
  regenerated schema/type fixtures.
  - Validated app-server behavior with unit and integration test suites,
  including status transitions and notifications.
