• [codex] Refactor marketplace add into shared core flow (#17717)

  ## Summary
  
  Move `codex marketplace add` onto a shared core implementation so the
  CLI and app-server path can use one source of truth.
  
  This change:
  - adds shared marketplace-add orchestration in `codex-core`
  - switches the CLI command to call that shared implementation
  - removes duplicated CLI-only marketplace add helpers
  - preserves focused parser and add-path coverage while moving the shared
  behavior into core tests
  
  ## Why
  
  The new `marketplace/add` RPC should reuse the same underlying
  marketplace-add flow as the CLI. This refactor lands that consolidation
  first so the follow-up app-server PR can be mostly protocol and handler
  wiring.
  
  ## Validation
  
  - `cargo test -p codex-core marketplace_add`
  - `cargo test -p codex-cli marketplace_cmd`
  - `just fix -p codex-core`
  - `just fix -p codex-cli`
  - `just fmt`

• Add turn item injection API (#17703)

  ## Summary
  - Add `turn/inject_items` app-server v2 request support for appending
  raw Responses API items to a loaded thread history without starting a
  turn.
  - Generate JSON schema and TypeScript protocol artifacts for the new
  params and empty response.
  - Document the new endpoint and include a request/response example.
  - Preserve compatibility with the typo alias `turn/injet_items` while
  returning the canonical method name.
  
  ## Testing
  - Not run (not requested)

• Option to Notify Workspace Owner When Usage Limit is Reached (#16969)

  ## Summary
  - Replace the manual `/notify-owner` flow with an inline confirmation
  prompt when a usage-based workspace member hits a credits-depleted
  limit.
  - Fetch the current workspace role from the live ChatGPT
  `accounts/check/v4-2023-04-27` endpoint so owner/member behavior matches
  the desktop and web clients.
  - Keep owner, member, and spend-cap messaging distinct so we only offer
  the owner nudge when the workspace is actually out of credits.
  
  ## What Changed
  - `backend-client`
  - Added a typed fetch for the current account role from
  `accounts/check`.
    - Mapped backend role values into a Rust workspace-role enum.
  - `app-server` and protocol
    - Added `workspaceRole` to `account/read` and `account/updated`.
  - Derived `isWorkspaceOwner` from the live role, with a fallback to the
  cached token claim when the role fetch is unavailable.
  - `tui`
    - Removed the explicit `/notify-owner` slash command.
  - When a member is blocked because the workspace is out of credits, the
  error now prompts:
  - `Your workspace is out of credits. Request more from your workspace
  owner? [y/N]`
    - Choosing `y` sends the existing owner-notification request.
  - Choosing `n`, pressing `Esc`, or accepting the default selection
  dismisses the prompt without sending anything.
  - Selection popups now honor explicit item shortcuts, which is how the
  `y` / `n` interaction is wired.
  
  ## Reviewer Notes
  - The main behavior change is scoped to usage-based workspace members
  whose workspace credits are depleted.
  - Spend-cap reached should not show the owner-notification prompt.
  - Owners and admins should continue to see `/usage` guidance instead of
  the member prompt.
  - The live role fetch is best-effort; if it fails, we fall back to the
  existing token-derived ownership signal.
  
  ## Testing
  - Manual verification
    - Workspace owner does not see the member prompt.
  - Workspace member with depleted credits sees the confirmation prompt
  and can send the nudge with `y`.
  - Workspace member with spend cap reached does not see the
  owner-notification prompt.

• Fix MCP tool listing for hyphenated server names (#16674)

  Addresses #16671 and #14927
  
  Problem: `mcpServerStatus/list` rebuilt MCP tool groups from sanitized
  tool prefixes but looked them up by unsanitized server names, so
  hyphenated servers rendered as having no tools in `/mcp`. This was
  reported as a regression when the TUI switched to use the app server.
  
  Solution: Build each server's tool map using the original server name's
  sanitized prefix, include effective runtime MCP servers in the status
  response, and add a regression test for hyphenated server names.

• core: remove cross-crate re-exports from lib.rs (#16512)

  ## Why
  
  `codex-core` was re-exporting APIs owned by sibling `codex-*` crates,
  which made downstream crates depend on `codex-core` as a proxy module
  instead of the actual owner crate.
  
  Removing those forwards makes crate boundaries explicit and lets leaf
  crates drop unnecessary `codex-core` dependencies. In this PR, this
  reduces the dependency on `codex-core` to `codex-login` in the following
  files:
  
  ```
  codex-rs/backend-client/Cargo.toml
  codex-rs/mcp-server/tests/common/Cargo.toml
  ```
  
  ## What
  
  - Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by
  `codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`,
  `codex-protocol`, `codex-shell-command`, `codex-sandboxing`,
  `codex-tools`, and `codex-utils-path`.
  - Delete the `default_client` forwarding shim in `codex-rs/core`.
  - Update in-crate and downstream callsites to import directly from the
  owning `codex-*` crate.
  - Add direct Cargo dependencies where callsites now target the owner
  crate, and remove `codex-core` from `codex-rs/backend-client`.

• Add ChatGPT device-code login to app server (#15525)

  ## Problem
  
  App-server clients could only initiate ChatGPT login through the browser
  callback flow, even though the shared login crate already supports
  device-code auth. That left VS Code, Codex App, and other app-server
  clients without a first-class way to use the existing device-code
  backend when browser redirects are brittle or when the client UX wants
  to own the login ceremony.
  
  ## Mental model
  
  This change adds a second ChatGPT login start path to app-server:
  clients can now call `account/login/start` with `type:
  "chatgptDeviceCode"`. App-server immediately returns a `loginId` plus
  the device-code UX payload (`verificationUrl` and `userCode`), then
  completes the login asynchronously in the background using the existing
  `codex_login` polling flow. Successful device-code login still resolves
  to ordinary `chatgpt` auth, and completion continues to flow through the
  existing `account/login/completed` and `account/updated` notifications.
  
  ## Non-goals
  
  This does not introduce a new auth mode, a new account shape, or a
  device-code eligibility discovery API. It also does not add automatic
  fallback to browser login in core; clients remain responsible for
  choosing when to request device code and whether to retry with a
  different UX if the backend/admin policy rejects it.
  
  ## Tradeoffs
  
  We intentionally keep `login_chatgpt_common` as a local validation
  helper instead of turning it into a capability probe. Device-code
  eligibility is checked by actually calling `request_device_code`, which
  means policy-disabled cases surface as an immediate request error rather
  than an async completion event. We also keep the active-login state
  machine minimal: browser and device-code logins share the same public
  cancel contract, but device-code cancellation is implemented with a
  local cancel token rather than a larger cross-crate refactor.
  
  ## Architecture
  
  The protocol grows a new `chatgptDeviceCode` request/response variant in
  app-server v2. On the server side, the new handler reuses the existing
  ChatGPT login precondition checks, calls `request_device_code`, returns
  the device-code payload, and then spawns a background task that waits on
  either cancellation or `complete_device_code_login`. On success, it
  reuses the existing auth reload and cloud-requirements refresh path
  before emitting `account/login/completed` success and `account/updated`.
  On failure or cancellation, it emits only `account/login/completed`
  failure. The existing `account/login/cancel { loginId }` contract
  remains unchanged and now works for both browser and device-code
  attempts.
  
  
  ## Tests
  
  Added protocol serialization coverage for the new request/response
  variant, plus app-server tests for device-code success, failure, cancel,
  and start-time rejection behavior. Existing browser ChatGPT login
  coverage remains in place to show that the callback-based flow is
  unchanged.

• app-server: add filesystem watch support (#14533)

  ### Summary
  Add the v2 app-server filesystem watch RPCs and notifications, wire them
  through the message processor, and implement connection-scoped watches
  with notify-backed change delivery. This also updates the schema
  fixtures, app-server documentation, and the v2 integration coverage for
  watch and unwatch behavior.
  
  This allows clients to efficiently watch for filesystem updates, e.g. to
  react on branch changes.
  
  ### Testing
  - exercise watch lifecycles for directory changes, atomic file
  replacement, missing-file targets, and unwatch cleanup

• Add thread/shellCommand to app server API surface (#14988)

  This PR adds a new `thread/shellCommand` app server API so clients can
  implement `!` shell commands. These commands are executed within the
  sandbox, and the command text and output are visible to the model.
  
  The internal implementation mirrors the current TUI `!` behavior.
  - persist shell command execution as `CommandExecution` thread items,
  including source and formatted output metadata
  - bridge live and replayed app-server command execution events back into
  the existing `tui_app_server` exec rendering path
  
  This PR also wires `tui_app_server` to submit `!` commands through the
  new API.

• Fix fuzzy search notification buffering in app-server tests (#14955)

  ## What is flaky
  `codex-rs/app-server/tests/suite/fuzzy_file_search.rs` intermittently
  loses the expected `fuzzyFileSearch/sessionUpdated` and
  `fuzzyFileSearch/sessionCompleted` notifications when multiple
  fuzzy-search sessions are active and CI delivers notifications out of
  order.
  
  ## Why it was flaky
  The wait helpers were keyed only by JSON-RPC method name.
  
  - `wait_for_session_updated` consumed the next
  `fuzzyFileSearch/sessionUpdated` notification even when it belonged to a
  different search session.
  - `wait_for_session_completed` did the same for
  `fuzzyFileSearch/sessionCompleted`.
  - Once an unmatched notification was read, it was dropped permanently
  instead of buffered.
  - That meant a valid completion for the target search could arrive
  slightly early, be consumed by the wrong waiter, and disappear before
  the test started waiting for it.
  
  The result depended on notification ordering and runner scheduling
  instead of on the actual product behavior.
  
  ## How this PR fixes it
  - Add a buffered notification reader in
  `codex-rs/app-server/tests/common/mcp_process.rs`.
  - Match fuzzy-search notifications on the identifying payload fields
  instead of matching only on method name.
  - Preserve unmatched notifications in the in-process queue so later
  waiters can still consume them.
  - Include pending notification methods in timeout failures to make
  future diagnosis concrete.
  
  ## Why this fix fixes the flakiness
  The test now behaves like a real consumer of an out-of-order event
  stream: notifications for other sessions stay buffered until the correct
  waiter asks for them. Reordering no longer loses the target event, so
  the test result is determined by whether the server emitted the right
  notifications, not by which one happened to be read first.

• Apply argument comment lint across codex-rs (#14652)

  ## Why
  
  Once the repo-local lint exists, `codex-rs` needs to follow the
  checked-in convention and CI needs to keep it from drifting. This commit
  applies the fallback `/*param*/` style consistently across existing
  positional literal call sites without changing those APIs.
  
  The longer-term preference is still to avoid APIs that require comments
  by choosing clearer parameter types and call shapes. This PR is
  intentionally the mechanical follow-through for the places where the
  existing signatures stay in place.
  
  After rebasing onto newer `main`, the rollout also had to cover newly
  introduced `tui_app_server` call sites. That made it clear the first cut
  of the CI job was too expensive for the common path: it was spending
  almost as much time installing `cargo-dylint` and re-testing the lint
  crate as a representative test job spends running product tests. The CI
  update keeps the full workspace enforcement but trims that extra
  overhead from ordinary `codex-rs` PRs.
  
  ## What changed
  
  - keep a dedicated `argument_comment_lint` job in `rust-ci`
  - mechanically annotate remaining opaque positional literals across
  `codex-rs` with exact `/*param*/` comments, including the rebased
  `tui_app_server` call sites that now fall under the lint
  - keep the checked-in style aligned with the lint policy by using
  `/*param*/` and leaving string and char literals uncommented
  - cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
  registry/git metadata in the lint job
  - split changed-path detection so the lint crate's own `cargo test` step
  runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
  - continue to run the repo wrapper over the `codex-rs` workspace, so
  product-code enforcement is unchanged
  
  Most of the code changes in this commit are intentionally mechanical
  comment rewrites or insertions driven by the lint itself.
  
  ## Verification
  
  - `./tools/argument-comment-lint/run.sh --workspace`
  - `cargo test -p codex-tui-app-server -p codex-tui`
  - parsed `.github/workflows/rust-ci.yml` locally with PyYAML

• app-server: add v2 filesystem APIs (#14245)

  Add a protocol-level filesystem surface to the v2 app-server so Codex
  clients can read and write files, inspect directories, and subscribe to
  path changes without relying on host-specific helpers.
  
  High-level changes:
  - define the new v2 fs/readFile, fs/writeFile, fs/createDirectory,
  fs/getMetadata, fs/readDirectory, fs/remove, fs/copy RPCs
  - implement the app-server handlers, including absolute-path validation,
  base64 file payloads, recursive copy/remove semantics
  - document the API, regenerate protocol schemas/types, and add
  end-to-end tests for filesystem operations, copy edge cases
  
  Testing plan:
  - validate protocol serialization and generated schema output for the
  new fs request, response, and notification types
  - run app-server integration coverage for file and directory CRUD paths,
  metadata/readDirectory responses, copy failure modes, and absolute-path
  validation

• chore(app-server): stop emitting codex/event/ notifications (#14392)

  ## Description
  
  This PR stops emitting legacy `codex/event/*` notifications from the
  public app-server transports.
  
  It's been a long time coming! app-server was still producing a raw
  notification stream from core, alongside the typed app-server
  notifications and server requests, for compatibility reasons. Now,
  external clients should no longer be depending on those legacy
  notifications, so this change removes them from the stdio and websocket
  contract and updates the surrounding docs, examples, and tests to match.
  
  ### Caveat
  I left the "in-process" version of app-server alone for now, since
  `codex exec` was recently based on top of app-server via this in-process
  form here: https://github.com/openai/codex/pull/14005
  
  Seems like `codex exec` still consumes some legacy notifications
  internally, so this branch only removes `codex/event/*` from app-server
  over stdio and websockets.
  
  ## Follow-up
  
  Once `codex exec` is fully migrated off `codex/event/*` notifications,
  we'll be able to stop emitting them entirely entirely instead of just
  filtering it at the external transport boundary.

• 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
  - `cargo test -p codex-state

• 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`

• 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

• 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`.

• Agent jobs (spawn_agents_on_csv) + progress UI (#10935)

  ## Summary
  - Add agent job support: spawn a batch of sub-agents from CSV, auto-run,
  auto-export, and store results in SQLite.
  - Simplify workflow: remove run/resume/get-status/export tools; spawn is
  deterministic and completes in one call.
  - Improve exec UX: stable, single-line progress bar with ETA; suppress
  sub-agent chatter in exec.
  
  ## Why
  Enables map-reduce style workflows over arbitrarily large repos using
  the existing Codex orchestrator. This addresses review feedback about
  overly complex job controls and non-deterministic monitoring.
  
  ## Demo (progress bar)
  ```
  ./codex-rs/target/debug/codex exec \
    --enable collab \
    --enable sqlite \
    --full-auto \
    --progress-cursor \
    -c agents.max_threads=16 \
    -C /Users/daveaitel/code/codex \
    - <<'PROMPT'
  Create /tmp/agent_job_progress_demo.csv with columns: path,area and 30 rows:
  path = item-01..item-30, area = test.
  
  Then call spawn_agents_on_csv with:
  - csv_path: /tmp/agent_job_progress_demo.csv
  - instruction: "Run `python - <<'PY'` to sleep a random 0.3–1.2s, then output JSON with keys: path, score (int). Set score = 1."
  - output_csv_path: /tmp/agent_job_progress_demo_out.csv
  PROMPT
  ```
  
  ## Review feedback addressed
  - Auto-start jobs on spawn; removed run/resume/status/export tools.
  - Auto-export on success.
  - More descriptive tool spec + clearer prompts.
  - Avoid deadlocks on spawn failure; pending/running handled safely.
  - Progress bar no longer scrolls; stable single-line redraw.
  
  ## Tests
  - `cd codex-rs && cargo test -p codex-exec`
  - `cd codex-rs && cargo build -p codex-cli`

• Add field to Thread object for the latest rename set for a given thread (#12301)

  Exposes through the app server updated names set for a thread. This
  enables other surfaces to use the core as the source of truth for thread
  naming. `threadName` is gathered using the helper functions used to
  interact with `session_index.jsonl`, and is hydrated in:
  - `thread/list`
  - `thread/read`
  - `thread/resume`
  - `thread/unarchive`
  - `thread/rollback`
  
  We don't do this for `thread/start` and `thread/fork`.

• tests: centralize in-flight turn cleanup helper (#12271)

  ## Why
  
  Several tests intentionally exercise behavior while a turn is still
  active. The cleanup sequence for those tests (`turn/interrupt` + waiting
  for `codex/event/turn_aborted`) was duplicated across files, which made
  the rationale easy to lose and the pattern easy to apply inconsistently.
  
  This change centralizes that cleanup in one place with a single
  explanatory doc comment.
  
  ## What Changed
  
  ### Added shared helper
  
  In `codex-rs/app-server/tests/common/mcp_process.rs`:
  
  - Added `McpProcess::interrupt_turn_and_wait_for_aborted(...)`.
  - Added a doc comment explaining why explicit interrupt + terminal wait
  is required for tests that intentionally leave a turn in-flight.
  
  ### Migrated call sites
  
  Replaced duplicated interrupt/aborted blocks with the helper in:
  
  - `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
    - `thread_resume_rejects_history_when_thread_is_running`
    - `thread_resume_rejects_mismatched_path_when_thread_is_running`
  - `codex-rs/app-server/tests/suite/v2/turn_start_zsh_fork.rs`
    - `turn_start_shell_zsh_fork_executes_command_v2`
  -
  `turn_start_shell_zsh_fork_subcommand_decline_marks_parent_declined_v2`
  - `codex-rs/app-server/tests/suite/v2/turn_steer.rs`
    - `turn_steer_returns_active_turn_id`
  
  ### Existing cleanup retained
  
  In `codex-rs/app-server/tests/suite/v2/turn_start.rs`:
  
  - `turn_start_accepts_local_image_input` continues to explicitly wait
  for `turn/completed` so the turn lifecycle is fully drained before test
  exit.
  
  ## Verification
  
  - `cargo test -p codex-app-server`

• app-server tests: reduce intermittent nextest LEAK via graceful child shutdown (#12266)

  ## Why
  `cargo nextest` was intermittently reporting `LEAK` for
  `codex-app-server` tests even when assertions passed. This adds noise
  and flakiness to local/CI signals.
  
  Sample output used as the basis of this investigation:
  
  ```text
  LEAK [   7.578s] ( 149/3663) codex-app-server::all suite::output_schema::send_user_turn_output_schema_is_per_turn_v1
  LEAK [   7.383s] ( 210/3663) codex-app-server::all suite::v2::dynamic_tools::dynamic_tool_call_round_trip_sends_text_content_items_to_model
  LEAK [   7.768s] ( 213/3663) codex-app-server::all suite::v2::dynamic_tools::thread_start_injects_dynamic_tools_into_model_requests
  LEAK [   8.841s] ( 224/3663) codex-app-server::all suite::v2::output_schema::turn_start_accepts_output_schema_v2
  LEAK [   8.151s] ( 225/3663) codex-app-server::all suite::v2::plan_item::plan_mode_uses_proposed_plan_block_for_plan_item
  LEAK [   8.230s] ( 232/3663) codex-app-server::all suite::v2::safety_check_downgrade::openai_model_header_mismatch_emits_model_rerouted_notification_v2
  LEAK [   6.472s] ( 273/3663) codex-app-server::all suite::v2::turn_start::turn_start_accepts_collaboration_mode_override_v2
  LEAK [   6.107s] ( 275/3663) codex-app-server::all suite::v2::turn_start::turn_start_accepts_personality_override_v2
  ```
  
  ## How I Reproduced
  I focused on the suspect tests and ran them under `nextest` stress mode
  with leak reporting enabled.
  
  ```bash
  cargo nextest run -p codex-app-server -j 2 --no-fail-fast --stress-count 25 --status-level leak --final-status-level fail -E 'test(suite::output_schema::send_user_turn_output_schema_is_per_turn_v1) | test(suite::v2::dynamic_tools::dynamic_tool_call_round_trip_sends_text_content_items_to_model) | test(suite::v2::dynamic_tools::thread_start_injects_dynamic_tools_into_model_requests) | test(suite::v2::output_schema::turn_start_accepts_output_schema_v2) | test(suite::v2::plan_item::plan_mode_uses_proposed_plan_block_for_plan_item) | test(suite::v2::safety_check_downgrade::openai_model_header_mismatch_emits_model_rerouted_notification_v2) | test(suite::v2::turn_start::turn_start_accepts_collaboration_mode_override_v2) | test(suite::v2::turn_start::turn_start_accepts_personality_override_v2)'
  ```
  
  This reproduced intermittent `LEAK` statuses while tests still passed.
  
  ## What Changed
  In `codex-rs/app-server/tests/common/mcp_process.rs`:
  
  - Changed `stdin: ChildStdin` to `stdin: Option<ChildStdin>` so teardown
  can explicitly close stdin.
  - In `Drop`, close stdin first to trigger EOF-based graceful shutdown.
  - Wait briefly for graceful exit.
  - If still running, fall back to `start_kill()` and the existing bounded
  `try_wait()` loop.
  - Updated send-path handling to bail if stdin is already closed.
  
  ## Why This Is the Right Fix
  The leak signal was caused by child-process teardown timing, not
  test-logic assertion failure. The helper previously relied mostly on
  force-kill timing in `Drop`; that can race with nextest leak detection.
  
  Closing stdin first gives `codex-app-server` a deterministic, graceful
  shutdown path before force-kill. Keeping the force-kill fallback
  preserves robustness if graceful shutdown does not complete in time.
  
  ## Verification
  - `cargo test -p codex-app-server`
  - Re-ran the stress repro above after this change: no `LEAK` statuses
  observed.
  - Additional high-signal stress run also showed no leaks:
  
  ```bash
  cargo nextest run -p codex-app-server -j 2 --no-fail-fast --stress-count 100 --status-level leak --final-status-level fail -E 'test(suite::output_schema::send_user_turn_output_schema_is_per_turn_v1) | test(suite::v2::dynamic_tools::dynamic_tool_call_round_trip_sends_text_content_items_to_model)'
  ```

• Stabilize app-server detached review and running-resume tests (#12203)

  ## Summary
  - stabilize
  `thread_resume_rejoins_running_thread_even_with_override_mismatch` by
  using a valid delayed second SSE response instead of an intentionally
  truncated stream
  - set `RUST_MIN_STACK=4194304` for spawned app-server test processes in
  `McpProcess` to avoid stack-sensitive CI overflows in detached review
  tests
  
  ## Why
  - the thread-resume assertion could race with a mocked stream-disconnect
  error and intermittently observe `systemError`
  - detached review startup is stack-sensitive in some CI environments;
  pinning a larger stack in the test harness removes that flake without
  changing product behavior
  
  ## Validation
  - `just fmt`
  - `cargo test -p codex-app-server --test all

  Reapply "Add app-server transport layer with websocket support" with
  additional fixes from https://github.com/openai/codex/pull/11313/changes
  to avoid deadlocking.
  
  This reverts commit 47356ff83c.
  
  ## Summary
  
  To avoid deadlocking when queues are full, we maintain separate tokio
  tasks dedicated to incoming vs outgoing event handling
  - split the app-server main loop into two tasks in
  `run_main_with_transport`
     - inbound handling (`transport_event_rx`)
     - outbound handling (`outgoing_rx` + `thread_created_rx`)
  - separate incoming and outgoing websocket tasks
  
  ## Validation
  
  Integration tests, testing thoroughly e2e in codex app w/ >10 concurrent

• fix(app-server): for external auth, replace id_token with chatgpt_acc… (#11240)

  …ount_id and chatgpt_plan_type
  
  ### Summary
  Following up on external auth mode which was introduced here:
  https://github.com/openai/codex/pull/10012
  
  Turns out some clients have a differently shaped ID token and don't have
  a chosen workspace (aka chatgpt_account_id) encoded in their ID token.
  So, let's replace `id_token` param with `chatgpt_account_id` and
  `chatgpt_plan_type` (optional) when initializing the external ChatGPT
  auth mode (`account/login/start` with `chatgptAuthTokens`).
  
  The client was able to test end-to-end with a Codex build from this
  branch and verified it worked!

• feat(app-server): turn/steer API (#10821)

  This PR adds a dedicated `turn/steer` API for appending user input to an
  in-flight turn.
  
  ## Motivation
  Currently, steering in the app is implemented by just calling
  `turn/start` while a turn is running. This has some really weird quirks:
  - Client gets back a new `turn.id`, even though streamed
  events/approvals remained tied to the original active turn ID.
  - All the various turn-level override params on `turn/start` do not
  apply to the "steer", and would only apply to the next real turn.
  - There can also be a race condition where the client thinks the turn is
  active but the server has already completed it, so there might be bugs
  if the client has baked in some client-specific behavior thinking it's a
  steer when in fact the server kicked off a new turn. This is
  particularly possible when running a client against a remote app-server.
  
  Having a dedicated `turn/steer` API eliminates all those quirks.
  
  `turn/steer` behavior:
  - Requires an active turn on threadId. Returns a JSON-RPC error if there
  is no active turn.
  - If expectedTurnId is provided, it must match the active turn (more
  useful when connecting to a remote app-server).
  - Does not emit `turn/started`.
  - Does not accept turn overrides (`cwd`, `model`, `sandbox`, etc.) or
  `outputSchema` to accurately reflect that these are not applied when
  steering.

• feat: experimental flags (#10231)

  ## Problem being solved
  - We need a single, reliable way to mark app-server API surface as
  experimental so that:
    1. the runtime can reject experimental usage unless the client opts in
  2. generated TS/JSON schemas can exclude experimental methods/fields for
  stable clients.
  
  Right now that’s easy to drift or miss when done ad-hoc.
  
  ## How to declare experimental methods and fields
  - **Experimental method**: add `#[experimental("method/name")]` to the
  `ClientRequest` variant in `client_request_definitions!`.
  - **Experimental field**: on the params struct, derive `ExperimentalApi`
  and annotate the field with `#[experimental("method/name.field")]` + set
  `inspect_params: true` for the method variant so
  `ClientRequest::experimental_reason()` inspects params for experimental
  fields.
  
  ## How the macro solves it
  - The new derive macro lives in
  `codex-rs/codex-experimental-api-macros/src/lib.rs` and is used via
  `#[derive(ExperimentalApi)]` plus `#[experimental("reason")]`
  attributes.
  - **Structs**:
  - Generates `ExperimentalApi::experimental_reason(&self)` that checks
  only annotated fields.
    - The “presence” check is type-aware:
      - `Option<T>`: `is_some_and(...)` recursively checks inner.
      - `Vec`/`HashMap`/`BTreeMap`: must be non-empty.
      - `bool`: must be `true`.
      - Other types: considered present (returns `true`).
  - Registers each experimental field in an `inventory` with `(type_name,
  serialized field name, reason)` and exposes `EXPERIMENTAL_FIELDS` for
  that type. Field names are converted from `snake_case` to `camelCase`
  for schema/TS filtering.
  - **Enums**:
  - Generates an exhaustive `match` returning `Some(reason)` for annotated
  variants and `None` otherwise (no wildcard arm).
  - **Wiring**:
  - Runtime gating uses `ExperimentalApi::experimental_reason()` in
  `codex-rs/app-server/src/message_processor.rs` to reject requests unless
  `InitializeParams.capabilities.experimental_api == true`.
  - Schema/TS export filters use the inventory list and
  `EXPERIMENTAL_CLIENT_METHODS` from `client_request_definitions!` to
  strip experimental methods/fields when `experimental_api` is false.
