• feat(app-server): add mcpServer/startupStatus/updated notification (#15220)

  Exposes the legacy `codex/event/mcp_startup_update` event as an API v2
  notification.
  
  The legacy event has this shape:
  ```
  #[derive(Debug, Clone, Deserialize, Serialize, JsonSchema, TS)]
  pub struct McpStartupUpdateEvent {
      /// Server name being started.
      pub server: String,
      /// Current startup status.
      pub status: McpStartupStatus,
  }
  
  #[derive(Debug, Clone, Deserialize, Serialize, JsonSchema, TS)]
  #[serde(rename_all = "snake_case", tag = "state")]
  #[ts(rename_all = "snake_case", tag = "state")]
  pub enum McpStartupStatus {
      Starting,
      Ready,
      Failed { error: String },
      Cancelled,
  }
  ```

• Plumb MCP turn metadata through _meta (#15190)

  ## Summary
  
  Some background. We're looking to instrument GA turns end to end. Right
  now a big gap is grouping mcp tool calls with their codex sessions. We
  send session id and turn id headers to the responses call but not the
  mcp/wham calls.
  
  Ideally we could pass the args as headers like with responses, but given
  the setup of the rmcp client, we can't send as headers without either
  changing the rmcp package upstream to allow per request headers or
  introducing a mutex which break concurrency. An earlier attempt made the
  assumption that we had 1 client per thread, which allowed us to set
  headers at the start of a turn. @pakrym mentioned that this assumption
  might break in the near future.
  
  So the solution now is to package the turn metadata/session id into the
  _meta field in the post body and pull out in codex-backend.
  
  - send turn metadata to MCP servers via `tools/call` `_meta` instead of
  assuming per-thread request headers on shared clients
  - preserve the existing `_codex_apps` metadata while adding
  `x-codex-turn-metadata` for all MCP tool calls
  - extend tests to cover both custom MCP servers and the codex apps

• add specific tool guidance for Windows destructive commands (#15207)

  updated Windows shell/unified_exec tool descriptions:
  
  `exec_command`
  ```text
  Runs a command in a PTY, returning output or a session ID for ongoing interaction.
  
  Windows safety rules:
  - Do not compose destructive filesystem commands across shells. Do not enumerate paths in PowerShell and then pass them to `cmd /c`, batch builtins, or another shell for deletion or moving. Use one shell end-to-end, prefer native PowerShell cmdlets such as `Remove-Item` / `Move-Item` with `-LiteralPath`, and avoid string-built shell commands for file operations.
  - Before any recursive delete or move on Windows, verify the resolved absolute target paths stay within the intended workspace or explicitly named target directory. Never issue a recursive delete or move against a computed path if the final target has not been checked.
  ```
  
  `shell`
  ```text
  Runs a Powershell command (Windows) and returns its output. Arguments to `shell` will be passed to CreateProcessW(). Most commands should be prefixed with ["powershell.exe", "-Command"].
  
  Examples of valid command strings:
  
  - ls -a (show hidden): ["powershell.exe", "-Command", "Get-ChildItem -Force"]
  - recursive find by name: ["powershell.exe", "-Command", "Get-ChildItem -Recurse -Filter *.py"]
  - recursive grep: ["powershell.exe", "-Command", "Get-ChildItem -Path C:\\myrepo -Recurse | Select-String -Pattern 'TODO' -CaseSensitive"]
  - ps aux | grep python: ["powershell.exe", "-Command", "Get-Process | Where-Object { $_.ProcessName -like '*python*' }"]
  - setting an env var: ["powershell.exe", "-Command", "$env:FOO='bar'; echo $env:FOO"]
  - running an inline Python script: ["powershell.exe", "-Command", "@'\nprint('Hello, world!')\n'@ | python -"]

• feat(tui): add /title terminal title configuration (#12334)

  ## Problem
  
  When multiple Codex sessions are open at once, terminal tabs and windows
  are hard to distinguish from each other. The existing status line only
  helps once the TUI is already focused, so it does not solve the "which
  tab is this?" problem.
  
  This PR adds a first-class `/title` command so the terminal window or
  tab title can carry a short, configurable summary of the current
  session.
  
  ## Screenshot
  
  <img width="849" height="320" alt="image"
  src="https://github.com/user-attachments/assets/8b112927-7890-45ed-bb1e-adf2f584663d"
  />
  
  ## Mental model
  
  `/statusline` and `/title` are separate status surfaces with different
  constraints. The status line is an in-app footer that can be denser and
  more detailed. The terminal title is external terminal metadata, so it
  needs short, stable segments that still make multiple sessions easy to
  tell apart.
  
  The `/title` configuration is an ordered list of compact items. By
  default it renders `spinner,project`, so active sessions show
  lightweight progress first while idle sessions still stay easy to
  disambiguate. Each configured item is omitted when its value is not
  currently available rather than forcing a placeholder.
  
  ## Non-goals
  
  This does not merge `/title` into `/statusline`, and it does not add an
  arbitrary free-form title string. The feature is intentionally limited
  to a small set of structured items so the title stays short and
  reviewable.
  
  This also does not attempt to restore whatever title the terminal or
  shell had before Codex started. When Codex clears the title, it clears
  the title Codex last wrote.
  
  ## Tradeoffs
  
  A separate `/title` command adds some conceptual overlap with
  `/statusline`, but it keeps title-specific constraints explicit instead
  of forcing the status line model to cover two different surfaces.
  
  Title refresh can happen frequently, so the implementation now shares
  parsing and git-branch orchestration between the status line and title
  paths, and caches the derived project-root name by cwd. That keeps the
  hot path cheap without introducing background polling.
  
  ## Architecture
  
  The TUI gets a new `/title` slash command and a dedicated picker UI for
  selecting and ordering terminal-title items. The chosen ids are
  persisted in `tui.terminal_title`, with `spinner` and `project` as the
  default when the config is unset. `status` remains available as a
  separate text item, so configurations like `spinner,status` render
  compact progress like `⠋ Working`.
  
  `ChatWidget` now refreshes both status surfaces through a shared
  `refresh_status_surfaces()` path. That shared path parses configured
  items once, warns on invalid ids once, synchronizes shared cached state
  such as git-branch lookup, then renders the footer status line and
  terminal title from the same snapshot.
  
  Low-level OSC title writes live in `codex-rs/tui/src/terminal_title.rs`,
  which owns the terminal write path and last-mile sanitization before
  emitting OSC 0.
  
  ## Security
  
  Terminal-title text is treated as untrusted display content before Codex
  emits it. The write path strips control characters, removes invisible
  and bidi formatting characters that can make the title visually
  misleading, normalizes whitespace, and caps the emitted length.
  
  References used while implementing this:
  
  - [xterm control
  sequences](https://invisible-island.net/xterm/ctlseqs/ctlseqs.html)
  - [WezTerm escape sequences](https://wezterm.org/escape-sequences.html)
  - [CWE-150: Improper Neutralization of Escape, Meta, or Control
  Sequences](https://cwe.mitre.org/data/definitions/150.html)

  - [Unicode Bidirectional Algorithm (UAX
  #9)](https://www.unicode.org/reports/tr9/)
  - [Unicode Security Considerations (UTR
  #36)](https://www.unicode.org/reports/tr36/)
  
  ## Observability
  
  Unknown configured title item ids are warned about once instead of
  repeatedly spamming the transcript. Live preview applies immediately
  while the `/title` picker is open, and cancel rolls the in-memory title
  selection back to the pre-picker value.
  
  If terminal title writes fail, the TUI emits debug logs around set and
  clear attempts. The rendered status label intentionally collapses richer
  internal states into compact title text such as `Starting...`, `Ready`,
  `Thinking...`, `Working...`, `Waiting...`, and `Undoing...` when
  `status` is configured.
  
  ## Tests
  
  Ran:
  
  - `just fmt`
  - `cargo test -p codex-tui`
  
  At the moment, the red Windows `rust-ci` failures are due to existing
  `codex-core` `apply_patch_cli` stack-overflow tests that also reproduce
  on `main`. The `/title`-specific `codex-tui` suite is green.

• Publish runnable DotSlash package for argument-comment lint (#15198)

  ## Why
  
  To date, the argument-comment linter introduced in
  https://github.com/openai/codex/pull/14651 had to be built from source
  to run, which can be a bit slow (both for local dev and when it is run
  in CI). Because of the potential slowness, I did not wire it up to run
  as part of `just clippy` or anything like that. As a result, I have seen
  a number of occasions where folks put up PRs that violate the lint, see
  it fail in CI, and then have to put up their PR again.
  
  The goal of this PR is to pre-build a runnable version of the linter and
  then make it available via a DotSlash file. Once it is available, I will
  update `just clippy` and other touchpoints to make it a natural part of
  the dev cycle so lint violations should get flagged _before_ putting up
  a PR for review.
  
  To get things started, we will build the DotSlash file as part of an
  alpha release. Though I don't expect the linter to change often, so I'll
  probably change this to only build as part of mainline releases once we
  have a working DotSlash file. (Ultimately, we should probably move the
  linter into its own repo so it can have its own release cycle.)
  
  ## What Changed
  - add a reusable `rust-release-argument-comment-lint.yml` workflow that
  builds host-specific archives for macOS arm64, Linux arm64/x64, and
  Windows x64
  - wire `rust-release.yml` to publish the `argument-comment-lint`
  DotSlash manifest on all releases for now, including alpha tags
  - package a runnable layout instead of a bare library
  
  The Unix archive layout is:
  
  ```text
  argument-comment-lint/
    bin/
      argument-comment-lint
      cargo-dylint
    lib/
      libargument_comment_lint@nightly-2025-09-18-<target>.dylib|so
  ```
  
  On Windows the same layout is published as a `.zip`, with `.exe` and
  `.dll` filenames instead.
  
  DotSlash resolves the package entrypoint to
  `argument-comment-lint/bin/argument-comment-lint`. That runner finds the
  sibling bundled `cargo-dylint` binary plus the single packaged Dylint
  library under `lib/`, then invokes `cargo-dylint dylint --lib-path
  <that-library>` with the repo's default lint settings.

• [hooks] use a user message > developer message for prompt continuation (#14867)

  ## Summary
  
  Persist Stop-hook continuation prompts as `user` messages instead of
  hidden `developer` messages + some requested integration tests
  
  This is a followup to @pakrym 's comment in
  https://github.com/openai/codex/pull/14532 to make sure stop-block
  continuation prompts match training for turn loops
  
  - Stop continuation now writes `<hook_prompt hook_run_id="...">stop
  hook's user prompt<hook_prompt>`
  - Introduces quick-xml dependency, though we already indirectly depended
  on it anyway via syntect
  - This PR only has about 500 lines of actual logic changes, the rest is
  tests/schema
  
  ## Testing
  
  Example run (with a sessionstart hook and 3 stop hooks) - this shows
  context added by session start, then two stop hooks sending their own
  additional prompts in a new turn. The model responds with a single
  message addressing both. Then when that turn ends, the hooks detect that
  they just ran using `stop_hook_active` and decide not to infinite loop
  
  test files for this (unzip, move codex -> .codex):

• Forward session and turn headers to MCP HTTP requests (#15011)

  ## Summary
  - forward request-scoped task headers through MCP tool metadata lookups
  and tool calls
  - apply those headers to streamable HTTP initialize, tools/list, and
  tools/call requests
  - update affected rmcp/core tests for the new request_headers plumbing
  
  ## Testing
  - cargo test -p codex-rmcp-client
  - cargo test -p codex-core (fails on pre-existing unrelated error in
  core/src/auth_env_telemetry.rs: missing websocket_connect_timeout_ms in
  ModelProviderInfo initializer)
  - just fix -p codex-rmcp-client
  - just fix -p codex-core (hits the same unrelated auth_env_telemetry.rs
  error)
  - just fmt

• feat(core, tracing): create turn spans over websockets (#14632)

  ## Description
  
  Dependent on:
  - [responsesapi] https://github.com/openai/openai/pull/760991 
  - [codex-backend] https://github.com/openai/openai/pull/760985
  
  `codex app-server -> codex-backend -> responsesapi` now reuses a
  persistent websocket connection across many turns. This PR updates
  tracing when using websockets so that each `response.create` websocket
  request propagates the current tracing context, so we can get a holistic
  end-to-end trace for each turn.
  
  Tracing is propagated via special keys (`ws_request_header_traceparent`,
  `ws_request_header_tracestate`) set in the `client_metadata` param in
  Responses API.
  
  Currently tracing on websockets is a bit broken because we only set
  tracing context on ws connection time, so it's detached from a
  `turn/start` request.

• Add Python SDK thread.run convenience methods (#15088)

  ## TL;DR
  Add `thread.run(...)` / `async thread.run(...)` convenience methods to
  the Python SDK for the common case.
  
  - add `RunInput = Input | str` and `RunResult` with `final_response`,
  collected `items`, and optional `usage`
  - keep `thread.turn(...)` strict and lower-level for streaming,
  steering, interrupting, and raw generated `Turn` access
  - update Python SDK docs, quickstart examples, and tests for the sync
  and async convenience flows
  
  ## Validation
  - `python3 -m pytest sdk/python/tests/test_public_api_signatures.py
  sdk/python/tests/test_public_api_runtime_behavior.py`
  - `python3 -m pytest
  sdk/python/tests/test_real_app_server_integration.py -k
  'thread_run_convenience or async_thread_run_convenience'` (skipped in
  this environment)

• Feat: reuse persisted model and reasoning effort on thread resume (#14888)

  ## Summary
  
  This PR makes `thread/resume` reuse persisted thread model metadata when
  the caller does not explicitly override it.
  
  Changes:
  - read persisted thread metadata from SQLite during `thread/resume`
  - reuse persisted `model` and `model_reasoning_effort` as resume-time
  defaults
  - fetch persisted metadata once and reuse it later in the resume
  response path
  - keep thread summary loading on the existing rollout path, while
  reusing persisted metadata when available
  - document the resume fallback behavior in the app-server README
  
  ## Why
  
  Before this change, resuming a thread without explicit overrides derived
  `model` and `model_reasoning_effort` from current config, which could
  drift from the thread’s last persisted values. That meant a resumed
  thread could report and run with different model settings than the ones
  it previously used.
  
  ## Behavior
  
  Precedence on `thread/resume` is now:
  1. explicit resume overrides
  2. persisted SQLite metadata for the thread
  3. normal config resolution for the resumed cwd

• Align SQLite feedback logs with feedback formatter (#13494)

  ## Summary
  - store a pre-rendered `feedback_log_body` in SQLite so `/feedback`
  exports keep span prefixes and structured event fields
  - render SQLite feedback exports with timestamps and level prefixes to
  match the old in-memory feedback formatter, while preserving existing
  trailing newlines
  - count `feedback_log_body` in the SQLite retention budget so structured
  or span-prefixed rows still prune correctly
  - bound `/feedback` row loading in SQL with the retention estimate, then
  apply exact whole-line truncation in Rust so uploads stay capped without
  splitting lines
  
  ## Details
  - add a `feedback_log_body` column to `logs` and backfill it from
  `message` for existing rows
  - capture span names plus formatted span and event fields at write time,
  since SQLite does not retain enough structure to reconstruct the old
  formatter later
  - keep SQLite feedback queries scoped to the requested thread plus
  same-process threadless rows
  - restore a SQL-side cumulative `estimated_bytes` cap for feedback
  export queries so over-retained partitions do not load every matching
  row before truncation
  - add focused formatting coverage for exported feedback lines and parity
  coverage against `tracing_subscriber`
  
  ## Testing
  - cargo test -p codex-state
  - just fix -p codex-state
  - just fmt

• fix: try to fix "Stage npm package" step in ci.yml (#15092)

  Fix the CI job by updating it to use artifacts from a more recent
  release (`0.115.0`) instead of the existing one (`0.74.0`).
  
  This step in our CI job on PRs started failing today:
  
  
  https://github.com/openai/codex/blob/334164a6f714c171bb9f6440c7d3cd04ec04d295/.github/workflows/ci.yml#L33-L47
  
  I believe it's because this test verifies that the "package npm" script
  works, but we want it to be fast and not wait for binaries to be built,
  so it uses a GitHub workflow that's already done. Because it was using a
  GitHub workflow associated with `0.74.0`, it seems likely that
  workflow's history has been reaped, so we need to use a newer one.

• feat(tui): restore composer history in app-server tui (#14945)

  ## Problem
  
  The app-server TUI (`tui_app_server`) lacked composer history support.
  Pressing Up/Down to recall previous prompts hit a stub that logged a
  warning and displayed "Not available in app-server TUI yet." New
  submissions were silently dropped from the shared history file, so
  nothing persisted for future sessions.
  
  ## Mental model
  
  Codex maintains a single, append-only history file
  (`$CODEX_HOME/history.jsonl`) shared across all TUI processes on the
  same machine. The legacy (in-process) TUI already reads/writes this file
  through `codex_core::message_history`. The app-server TUI delegates most
  operations to a separate process over RPC, but history is intentionally
  *not* an RPC concern — it's a client-local file.
  
  This PR makes the app-server TUI access the same history file directly,
  bypassing the app-server process entirely. The composer's Up/Down
  navigation and submit-time persistence now follow the same code paths as
  the legacy TUI, with the only difference being *where* the call is
  dispatched (locally in `App`, rather than inside `CodexThread`).
  
  The branch is rebuilt directly on top of `upstream/main`, so it keeps
  the
  existing app-server restore architecture intact.
  `AppServerStartedThread`
  still restores transcript history from the server `Thread` snapshot via
  `thread_snapshot_events`; this PR only adds composer-history support.
  
  ## Non-goals
  
  - Adding history support to the app-server protocol. History remains
  client-local.
  - Changing the on-disk format or location of `history.jsonl`.
  - Surfacing history I/O errors to the user (failures are logged and
  silently swallowed, matching the legacy TUI).
  
  ## Tradeoffs
  
  | Decision | Why | Risk |
  |----------|-----|------|
  | Widen `message_history` from `pub(crate)` to `pub` | Avoids
  duplicating file I/O logic; the module already has a clean, minimal API
  surface. | Other workspace crates can now call these functions — the
  contract is no longer crate-private. However, this is consistent with
  recent precedent: `590cfa617` exposed `mention_syntax` for TUI
  consumption, `752402c4f` exposed plugin APIs (`PluginsManager`), and
  `14fcb6645`/`edacbf7b6` widened internal core APIs for other crates.
  These were all narrow, intentional exposures of specific APIs — not
  broad "make internals public" moves. `1af2a37ad` even went the other
  direction, reducing broad re-exports to tighten boundaries. This change
  follows the same pattern: a small, deliberate API surface (3 functions)
  rather than a wholesale visibility change. |
  | Intercept `AddToHistory` / `GetHistoryEntryRequest` in `App` before
  RPC fallback | Keeps history ops out of the "unsupported op" error path
  without changing app-server protocol. | This now routes through a single
  `submit_thread_op` entry point, which is safer than the original
  duplicated dispatch. The remaining risk is organizational: future
  thread-op submission paths need to keep using that shared entry point. |
  | `session_configured_from_thread_response` is now `async` | Needs
  `await` on `history_metadata()` to populate real `history_log_id` /
  `history_entry_count`. | Adds an async file-stat + full-file newline
  scan to the session bootstrap path. The scan is bounded by
  `history.max_bytes` and matches the legacy TUI's cost profile, but
  startup latency still scales with file size. |

  ```
  
  ## Observability
  
  - `tracing::warn` on `append_entry` failure (includes thread ID).
  - `tracing::warn` on `spawn_blocking` lookup join error.
  - `tracing::warn` from `message_history` internals on file-open, lock,
  or parse failures.
  
  ## Tests
  
  - `chat_composer_history::tests::navigation_with_async_fetch` — verifies
  that Up emits `Op::GetHistoryEntryRequest` (was: checked for stub error
  cell).
  - `app::tests::history_lookup_response_is_routed_to_requesting_thread` —
  verifies multi-thread composer recall routes the lookup result back to
  the originating thread.
  -
  `app_server_session::tests::resume_response_relies_on_snapshot_replay_not_initial_messages`
  — verifies app-server session restore still uses the upstream
  thread-snapshot path.
  -
  `app_server_session::tests::session_configured_populates_history_metadata`
  — verifies bootstrap sets nonzero `history_log_id` /
  `history_entry_count` from the shared local history file.
