• Read cached metadata for installed Git plugins (#20825)

  ## Summary
  - Populate `plugin/list` interface metadata for installed Git-sourced
  marketplace plugins from the active cached plugin bundle.
  - Preserve marketplace category precedence so list behavior matches
  `plugin/read`.
  - Keep existing fallback behavior when the cache or manifest is missing
  or invalid.
  
  ## Test Plan
  - `cd codex-rs && just fmt`
  - `cd codex-rs && cargo test -p codex-core-plugins
  list_marketplaces_installed_git_source_reads_metadata_from_cache_without_cloning`
  - `cd codex-rs && cargo test -p codex-app-server
  plugin_list_returns_installed_git_source_interface_from_cache`
  - `cd codex-rs && just fix -p codex-core-plugins`
  - `cd codex-rs && just fix -p codex-app-server`
  - `git diff --check`
  
  Server-truth check: OpenAI monorepo app-server generated types already
  expose `PluginSummary.interface`, and the webview consumes it for plugin
  cards. This PR keeps the protocol/schema unchanged and fills the
  existing field from the cached installed bundle for Git-backed
  cross-repo plugins.

• feat(tui): render responsive Markdown tables in TUI (#22052)

  ## Why
  
  The TUI currently treats Markdown tables as ordinary wrapped text, which
  makes table-heavy responses hard to read and brittle across narrow panes
  and terminal resizes.
  
  This change teaches the TUI to render Markdown tables responsively while
  preserving the raw Markdown source needed to re-render streamed and
  finalized transcript content after width changes. The goal is to keep
  tables legible during streaming, after resize, and once a turn has
  finished, without corrupting scrollback ordering.
  
  ## What Changed
  
  - add table detection and responsive table rendering in the Markdown
  renderer
  - render standard tables with Unicode box-drawing borders when the pane
  is wide enough
  - add a vertical readability fallback for constrained or dense tables so
  narrow panes still show each row clearly
  - keep links and `<br>` content inside table cells instead of leaking
  text outside the table
  - avoid table normalization inside fenced or indented code blocks
  - preserve raw streamed Markdown source and keep the active table as a
  mutable tail until finalization
  - consolidate finalized streamed content into source-backed transcript
  cells so post-resize re-rendering stays correct
  - add snapshot and targeted streaming/resize regression coverage for the
  new table behavior
  
  ## How to Test
  
  1. Start Codex TUI from this branch.
  2. Paste this exact prompt:
  `This is a session to test codex, no need to do any thinking, just end
  different markdown tables, with columns exploring different markdown
  contents, like links, bold italic, code, etc. Make them different sizes,
  some 30+ rows, some not and intertwine them with some paragraphs with
  complex formatting as well.`
  3. Confirm the response includes several Markdown tables mixed with
  richly formatted paragraphs.
  4. Confirm wide-enough tables render with box-drawing borders instead of
  plain wrapped pipe text.
  5. Resize the terminal narrower while the answer is still streaming and
  confirm the in-progress table stays coherent instead of duplicating
  headers or leaving broken scrollback behind.
  6. Resize again after the turn finishes and confirm the finalized
  transcript re-renders cleanly at the new width.
  7. In a narrow pane, verify dense tables fall back to the vertical
  per-row layout instead of producing unreadable wrapped columns.
  8. Also verify pipe-heavy fenced code blocks still render as code, not
  as tables.
  
  Targeted tests:
  - `cargo test -p codex-tui table_readability_fallback --no-fail-fast`
  - `cargo test -p codex-tui markdown_render --no-fail-fast`
  - `cargo test -p codex-tui streaming::controller --no-fail-fast`
  - `cargo test -p codex-tui table_resize_lifecycle --no-fail-fast`
  
  ## Docs
  
  No developer docs update appears necessary.

• Deduplicate issue digest interactions by user (#22039)

  ## Summary
  
  The issue digest uses recent posts, comments, and reactions to decide
  which issues deserve attention. A single active user could previously
  raise an issue's apparent importance by commenting or reacting multiple
  times in the window.
  
  This changes `codex-issue-digest` so `user_interactions` counts unique
  human GitHub users per issue across new issue posts, new comments, and
  new reactions. Raw reaction/comment counts are still preserved for
  detail output, and the skill guidance now describes `Interactions` as a
  unique-human-user count.

• fix(tui): suppress taskkill output for MCP teardown on Windows (#21759)

  ## Why
  
  On native Windows, running `/mcp` can leak `taskkill`'s normal
  `SUCCESS:` messages into the Codex TUI while the temporary MCP inventory
  process tree is being torn down. That corrupts the screen even though
  MCP itself is working correctly.
  
  Fixes #20845.
  
  ## What Changed
  
  - Redirect the Windows-only MCP teardown `taskkill` subprocess to null
  stdio so its console output cannot reach the TUI.
  
  ## How to Test
  
  1. On native Windows, configure a stdio MCP server, for example:
     ```powershell
  codex mcp add sequential-thinking -- npx -y
  @modelcontextprotocol/server-sequential-thinking
     ```
  2. With the latest released Codex CLI, start Codex and run `/mcp`.
  3. Confirm the current behavior: `taskkill` `SUCCESS:` lines appear in
  the TUI during the MCP refresh.
  4. Switch to this branch's build, start Codex again, and run `/mcp`.
  5. Confirm the MCP inventory still renders normally and the `taskkill`
  lines no longer appear.
  6. Repeat `/mcp` once more on this branch to verify the regression does
  not recur on repeated inventory requests.
  
  Targeted tests:
  - `cargo test -p codex-rmcp-client`
  - `cargo test -p codex-rmcp-client --test process_group_cleanup --quiet`

• fix(tui): preserve Shift+Enter in tmux csi-u panes (#21943)

  ## Why
  
  Inside tmux, `Shift+Enter` can still reach Codex as a plain `Enter` even
  when tmux has extended keys enabled. In `csi-u` tmux panes, Codex needs
  to request `modifyOtherKeys` mode 2 so tmux moves the pane from `VT10x`
  into extended-key mode and preserves the Shift modifier. Without that
  extra request, composer `Shift+Enter` submits the draft instead of
  inserting a newline.
  
  Fixes #21699.
  
  ## What Changed
  
  - Detect tmux sessions and read the active `extended-keys-format`,
  preferring the pane-local value before falling back to the global
  option.
  - Request `modifyOtherKeys` mode 2 for tmux panes using `csi-u` extended
  keys, and reset it when restoring keyboard reporting.
  - Add unit coverage for tmux detection, the format gate, and the emitted
  `modifyOtherKeys` escape sequence.
  
  ## How to Test
  
  1. In tmux, configure:
     ```tmux
     set-option -g extended-keys on
     set-option -g extended-keys-format csi-u
     ```
  2. Start Codex in a fresh tmux pane from this branch.
  3. From another pane, confirm the Codex pane reports `mode=Ext 2`:
     ```bash
  tmux list-panes -a -F '#{session_name}:#{window_index}.#{pane_index}
  mode=#{pane_key_mode} cmd=#{pane_current_command}'
     ```
  4. Type a draft in the composer and press `Shift+Enter`; confirm it
  inserts a newline instead of submitting.
  5. Also confirm plain `Enter` still submits as before.
  
  Targeted tests:
  - `cargo test -p codex-tui`
  
  ## Notes
  
  - Manual verification used both real `Shift+Enter` in iTerm2/tmux and
  `tmux send-keys ... S-Enter` to confirm the tmux pane changes from
  `VT10x` to `Ext 2` and preserves newline behavior.
  - On this checkout, the broader `codex-tui` test run currently reaches
  unrelated existing failures in `status::tests::*` plus a later stack
  overflow in
  `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.

• Persist 'priority' service tier as fast in config (#21991)

  ### Motivation
  - Normalize persisted service tier so selecting the request value
  `priority` (or legacy `fast`) is stored as `fast` while preserving
  unknown tier IDs and keeping request-time behavior unchanged.
  
  ### Description
  - Update persistence logic in `codex-rs/core/src/config/edit.rs` so
  `ConfigEdit::SetServiceTier` maps request values: `priority`/`fast` ->
  `"fast"`, `flex` -> `"flex"`, and leaves unknown strings unchanged.
  - Add unit tests in `codex-rs/core/src/config/edit_tests.rs` that verify
  a `priority` selection is written to `config.toml` as `"fast"` and that
  unknown tiers are preserved.
  - Add a config load test in `codex-rs/core/src/config/config_tests.rs`
  to ensure `service_tier = "priority"` still resolves to the `priority`
  request value at load time.
  - Add the required import `use
  codex_protocol::config_types::ServiceTier;` to the edited modules.
  
  ### Testing
  - Ran `just fmt` and `just fix -p codex-core` to apply formatting and
  lints and they completed successfully.
  - Ran `cargo test -p codex-core --lib service_tier` (focused unit tests
  for the change) and the tests passed.
  - Ran `cargo test -p codex-protocol` and the protocol test suite passed.
  - Note: an initial broader `cargo test -p codex-core service_tier`
  invocation matched integration tests and produced unrelated
  failures/hangs, so that run was interrupted and the focused `--lib`
  unit-test invocation was used instead.

• Split ChatWidget state into focused modules (#21866)

  ## Summary
  
  `ChatWidget` has been carrying several independent domains in one large
  state bag: transcript bookkeeping, turn lifecycle, queued input, status
  surfaces, connectors, review mode, and protocol dispatch. That makes
  otherwise-local changes hard to reason about because unrelated fields
  and side effects live beside each other in `chatwidget.rs`.
  
  This is the first cleanup PR in a larger decomposition effort. It does
  not try to make `chatwidget.rs` small in one sweep; instead, it
  establishes focused state boundaries that later handler, popup,
  rendering, and effect-synchronization extractions can build on.
  
  This PR keeps `ChatWidget` as the composition layer while moving focused
  state into smaller `codex-tui` modules. The widget still owns effects
  that touch the bottom pane, app events, command submission, redraw
  scheduling, and terminal-title updates.
  
  ## Changes
  
  - Add focused state modules under `codex-rs/tui/src/chatwidget/` for
  input queues, turn lifecycle, transcript bookkeeping, status state,
  connectors, review mode, and app-server protocol dispatch.
  - Update `ChatWidget` to hold grouped state structs and route
  input/lifecycle/status operations through those focused helpers.
  - Move app-server notification dispatch into `chatwidget/protocol.rs`
  while leaving feature handlers and side effects on `ChatWidget`.
  - Replace the large manual `ChatWidget` test literal with the normal
  constructor plus narrow test overrides, so future state moves do not
  require every field to be restated in test setup.
  - Update existing tests to access the new grouped state or narrower
  helpers without changing snapshot behavior.
  
  ## Longer-term direction
  
  Follow-up PRs can continue shrinking `chatwidget.rs` by moving behavior,
  not just state, into focused modules:
  
  - Extract input/submission flow, turn/stream handling, and tool-cell
  lifecycles into domain modules that call the new state reducers.
  - Move popup/settings builders and rendering helpers out of the main
  widget file so `ChatWidget` stays focused on composition.
  - Reduce direct `BottomPane` mutation by applying domain-specific sync
  outputs at clearer boundaries.

• Avoid blocking TUI on agent metadata hydration (#21870)

  ## Why
  
  Fixes #16688.
  
  The TUI currently hydrates collab receiver metadata by awaiting
  `thread/read` before each active-thread notification is rendered. During
  large subagent fan-outs, the embedded app-server can be busy starting
  agents and processing spawn work, so those synchronous metadata reads
  queue behind the fan-out and block the TUI event loop. That makes the UI
  appear frozen even though the underlying agent work can continue.
  
  ## What Changed
  
  - Replaced eager `thread/read` metadata hydration on the active
  notification path with local receiver-thread caching.
  - Kept `ThreadStarted` and picker refreshes as the places that fill in
  agent nickname/role metadata when it is available.
  - Skipped caching receiver threads that are explicitly reported as
  `NotFound`, avoiding live-looking ghost entries for failed stale-agent
  calls.
  - Added TUI tests covering both local receiver caching and `NotFound`
  suppression.
  
  ## Verification
  
  - `cargo test -p codex-tui collab_receiver_notification`
  - `just fix -p codex-tui`
  
  I also ran the full `cargo test -p codex-tui`; the new test passed, but
  the full process later aborted with an unrelated stack overflow in
  `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.

• Improve hooks trust flow in TUI (#21755)

  # Why
  Hooks that need trust review were easy to miss, and the existing TUI
  flow made users discover `/hooks` manually before they could decide
  whether to inspect or trust them.
  
  # What
  - add a startup review prompt for new or changed hooks before normal
  composer use
  - add a top-level `t` shortcut in `/hooks` to trust every review-needed
  hook at once
  - make pending-review rows and helper copy use warning styling
  
  ## TUI
  
  ### Startup review interstitial
  
  ```text
  Hooks need review
  2 hooks are new or changed.
  Hooks can run outside the sandbox after you trust them.
  
  › 1. Review hooks
    2. Trust all and continue
    3. Continue without trusting (hooks won't run)
  ```
  
  ### Top-level `/hooks` page when review is needed
  
  ```text
  Hooks
  Lifecycle hooks from config and enabled plugins.
  
  ⚠ 1 hook needs review before it can run.

• fix(tui): improve light-mode selection contrast (#21950)

  ## Why
  
  On light terminal backgrounds, selected rows in several TUI pickers were
  rendered with the same bright cyan accent used on dark themes. Against
  the light menu surface, that made the current selection hard to
  distinguish at a glance.
  
  <table><tr>
  <td>
  <p align="center">Before</p>
  <img width="1109" height="864" alt="SCR-20260509-nmtz"
  src="https://github.com/user-attachments/assets/b31ce0d0-19c2-4bdd-a220-7acc77bd8e8e"
  />
  </td>
  <td>
  <p align="center">After</p>
  <img width="1164" height="844" alt="SCR-20260509-nmox"
  src="https://github.com/user-attachments/assets/7b3fede0-4739-4a9f-a979-cdbb7451841f"
  />
  </td>
  </tr></table>
  
  ## What changed
  
  - Added a shared background-aware accent style for active/selected TUI
  controls.
  - Use a darker cyan-family accent on light backgrounds while preserving
  the existing bright cyan accent on dark or unknown backgrounds.
  - Reused that accent across shared picker rows and the custom
  selection-like surfaces that had drifted separately: picker tabs, hooks
  browsing, external-agent migration choices, and /keymap affordances.
  - Added focused tests for the light/dark accent rule and rendered
  selected-row styling.
  
  ## How to Test
  
  1. Start Codex in a terminal using a light background theme.
  2. Type `/` to open the slash-command picker and move the selection
  through a few rows.
  3. Confirm that the selected row is visibly colored with strong contrast
  instead of blending into the popup surface.
  4. Open `/keymap` and confirm the active tab, selected rows, and picker
  hint accents use the same light-theme accent treatment.
  5. In a dark terminal theme, repeat the slash-picker check and confirm
  the existing bright cyan selection styling is preserved.
  
  Targeted tests:
  - `cargo test -p codex-tui accent_style_uses_`
  - `cargo test -p codex-tui selected_rows_use_the_shared_accent_style`
  - `cargo test -p codex-tui
  selected_event_rows_use_the_shared_accent_style`
  
  Notes:
  - A full `cargo test -p codex-tui` run reached the end of the suite but
  hit an unrelated existing stack overflow in
  `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.

• fix(tui): preserve wrapped prose beside URLs (#21760)

  ## Why
  
  Mixed prose lines that contained URLs started taking the URL-preserving
  wrapping path, but that path could split ordinary words mid-token. A
  follow-up issue remained in scrollback insertion: when already-rendered
  indented rows were wrapped again, continuation rows could lose their
  margin and fall back to terminal hard wrapping. Together those bugs made
  normal Markdown output look broken around links, lists, blockquotes, and
  indented content.
  
  Separately, the local argument-comment lint wrappers failed under
  environments that set `PYTHONSAFEPATH=1`, because Python no longer adds
  the script directory to `sys.path` automatically. That prevented the
  lint from reaching Rust callsites at all.
  
  <img width="1778" height="1558" alt="CleanShot 2026-05-09 at 11 51 38"
  src="https://github.com/user-attachments/assets/9274d150-1757-4f1a-89ac-5bdc9997d8cb"
  />
  
  ## What Changed
  
  - Preserve URL tokens without turning every neighboring prose word into
  a character-level split point.
  - Add a mixed URL/prose wrapper that keeps ordinary words whole,
  preserves leading whitespace, and re-splits long non-URL tokens against
  the actual width available on continuation rows.
  - Reuse a rendered history row's leading whitespace as the continuation
  indent when scrollback insertion has to pre-wrap it again.
  - Add regression coverage for markdown wrapping, history-cell rendering,
  scrollback continuation margins, leading-indent width accounting, and
  continuation-row re-splitting.
  - Make both argument-comment lint entrypoints explicitly add their own
  directory to `sys.path`, so sibling imports still work when
  `PYTHONSAFEPATH=1`.
  
  ## How to Test
  
  1. Start Codex and render a long Markdown response that mixes prose with
  inline links, blockquotes, lists, and indented code-like text.
  2. Confirm that ordinary words next to links stay whole instead of
  breaking mid-word.
  3. Resize or replay the transcript and confirm wrapped continuation rows
  keep their expected left margin for blockquotes, lists, and indented
  content.
  4. Run the source argument-comment lint from a shell with
  `PYTHONSAFEPATH=1` and confirm it starts normally instead of failing to
  import `wrapper_common`.
  
  Targeted tests:
  - `cargo test -p codex-tui mixed_line --lib`
  - `cargo test -p codex-tui preserves_prefix_on_wrapped_rows --lib`
  - `cargo test -p codex-tui
  agent_markdown_cell_does_not_split_words_after_inline_markdown --lib`
  - `cargo test -p codex-tui
  mixed_url_markdown_wraps_prose_without_splitting_words_snapshot --lib`
  - `python3 tools/argument-comment-lint/test_wrapper_common.py`
  - `just argument-comment-lint-from-source -p codex-tui -- --lib`
  
  Notes:
  - `cargo test -p codex-tui` currently reaches the new tests
  successfully, then still aborts in the pre-existing
  `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`
  stack-overflow failure.

• tests: cover sandbox link write behavior (#21819)

  ## Why
  
  [PR #1705](https://github.com/openai/codex/pull/1705) moved
  `apply_patch` execution under the configured sandbox and called out the
  need for integration coverage. We already covered textual `../` escapes,
  but did not have coverage for link aliases that live inside a writable
  workspace while pointing at, or aliasing, files visible outside it.
  
  This PR locks in the current sandbox boundary without changing
  production write semantics. Symlink escapes into a read-only outside
  root should fail and leave the outside file unchanged. Existing hard
  links are characterized separately: if a user-created hard link already
  exists inside the writable root, sandboxed writes preserve normal
  hard-link semantics rather than replacing the link and silently breaking
  that relationship.
  
  ## What Changed
  
  - Added
  `apply_patch_cli_does_not_write_through_symlink_escape_outside_workspace`
  to verify `apply_patch` cannot update a symlink that targets a file
  outside the writable workspace.
  - Added `apply_patch_cli_preserves_existing_hard_link_outside_workspace`
  to verify `apply_patch` intentionally writes through an existing hard
  link and does not unlink or replace it.
  - Added `file_system_sandboxed_write_preserves_existing_hard_link` to
  verify sandboxed `fs/writeFile` preserves an existing hard link and
  writes the shared inode.
  
  ## Testing
  
  - `cargo test -p codex-exec-server file_system_sandboxed_write`
  - `cargo test -p codex-core
  apply_patch_cli_does_not_write_through_symlink_escape_outside_workspace`
  - `cargo test -p codex-core
  apply_patch_cli_preserves_existing_hard_link_outside_workspace`
  - `just fix -p codex-exec-server -p codex-core`
  - `just fix -p codex-core`

• [codex] Lowercase TUI service tier commands (#21906)

  ## Why
  
  Service-tier slash commands are built from model-catalog metadata. If
  the catalog returns a name like `Fast`, the TUI currently exposes
  `/Fast` and exact dispatch expects that casing, which is inconsistent
  with the lowercase command style used elsewhere.
  
  ## What
  
  - Lowercase service-tier command names when converting catalog tiers
  into `ServiceTierCommand` values.
  - Add regression coverage that seeds a catalog tier named `Fast` and
  expects the generated command to be `fast`.
  
  ## Testing
  
  Not run locally per repo instruction; PR CI should run the new
  `service_tier_commands_lowercase_catalog_names` coverage.

• Route Python SDK turn notifications by ID (#21778)

  ## Why
  
  The Python SDK previously protected the stdio transport with a single
  active turn-consumer guard. That avoided competing reads from stdout,
  but it also meant one `Codex`/`AsyncCodex` client could not stream
  multiple active turns at the same time. Notifications could also arrive
  before the caller received a `TurnHandle` and registered for streaming,
  so the SDK needed an explicit routing layer instead of letting
  individual API calls read directly from the shared transport.
  
  ## What Changed
  
  - Added a private `MessageRouter` that owns per-request response queues,
  per-turn notification queues, pending turn-notification replay, and
  global notification delivery behind a single stdout reader thread.
  - Generated typed notification routing metadata so turn IDs come from
  known payload shapes instead of router-side attribute guessing, with
  explicit fallback handling for unknown notification payloads.
  - Updated sync and async turn streaming so `TurnHandle.stream()`/`run()`
  and `stream_text()` consume only notifications for their own turn ID,
  while `AsyncAppServerClient` no longer serializes all transport calls
  behind one async lock.
  - Cleared pending turn-notification buffers when unregistered turns
  complete so never-consumed turn handles do not leave stale queues
  behind.
  - Removed the internal stream-until helper now that turn completion
  waiting can register directly with routed turn notifications.
  - Updated Python SDK docs and focused tests for concurrent transport
  calls, interleaved turn routing, buffered early notifications, unknown
  notification routing, async delegation, and routed turn completion
  behavior.

• [codex] compact network context rendering (#21875)

  ## Why
  
  The model-visible `<network>` context currently repeats indentation and
  a pair of XML tags for every allowed or denied domain. Large domain sets
  spend a surprising amount of prompt budget on that scaffolding instead
  of the actual policy values.
  
  ## What changed
  
  - Render allowed domains as one comma-separated `<allowed>` value
  instead of one element per domain.
  - Render denied domains the same way.
  - Keep the full allow/deny domain sets model-visible while updating the
  serialization and settings-update coverage for the denser shape.
  
  ## Example
  
  Before:
  ```xml
  <network enabled="true">
    <allowed>api.example.test</allowed>
    <allowed>cdn.example.test</allowed>
    <denied>blocked.example.test</denied>
  </network>
  ```
  
  After:
  ```xml
  <network enabled="true"><allowed>api.example.test,cdn.example.test</allowed><denied>blocked.example.test</denied></network>
  ```
  
  ## Validation
  
  - `cargo test -p codex-core environment_context`
  - `cargo test -p codex-core
  build_settings_update_items_emits_environment_item_for_network_changes`
  - Ran a local `codex` session with a real network context containing 121
  allowed domains and 42 denied domains, then inspected the raw prompt
  with `raw_token_viewer_cli.py`. With the same domain set, the rendered
  `<network>` section shrank from 7,175 characters across 161 lines to
  3,666 characters on one line, and the containing environment-context
  block fell from 6,428 tokens to 5,379 tokens.

• Move file watcher out of core (#21290)

  ## Why
  
  The app-server watcher relocation leaves the generic filesystem watcher
  as the last watcher-specific implementation still living inside
  `codex-core`. Moving that code to a small crate keeps `codex-core`
  focused on thread execution and lets app-server depend on the watcher
  without reaching back into core for filesystem watching primitives.
  
  This PR is stacked on #21287.
  
  ## What changed
  
  - Added a new `codex-file-watcher` crate containing the existing watcher
  implementation and its unit tests.
  - Updated app-server `fs_watch`, `skills_watcher`, and listener state to
  import watcher types from `codex-file-watcher`.
  - Removed the `file_watcher` module and `notify` dependency from
  `codex-core`.
  - Updated Cargo workspace metadata and `Cargo.lock` for the new internal
  crate.
  
  ## Validation
  
  - `cargo check -p codex-file-watcher -p codex-core -p codex-app-server`

• Reapply "Move skills watcher to app-server" (#21652)

  ## Why
  
  PR #21460 reverted the earlier move of skills change watching from
  `codex-core` into app-server. This reapplies that boundary change so
  app-server owns client-facing `skills/changed` notifications and core no
  longer carries the watcher.
  
  ## What
  
  - Restore the app-server `SkillsWatcher` and register it from thread
  listener setup.
  - Remove the core-owned skills watcher and its core live-reload
  integration surface.
  - Restore app-server coverage for `skills/changed` notifications after a
  watched skill file changes.

• sqlite: no more destructive version bumps (#21847)

  ## Why
  
  We'd like SQLite state to become required and load-bearing. As a first
  step, let's remove the mechanism that allows us to blow away the SQLite
  DB on a version bump, and instead rely on graceful migrations.
  
  The original motivation
  ([PR](https://github.com/openai/codex/pull/10623)) behind this mechanism
  was to care less about backwards compatibility while SQLite was being
  landed, but I'd say it's quite important now to keep the data in it.
  
  ## What changed
  
  - Make `STATE_DB_FILENAME` and `LOGS_DB_FILENAME` the full canonical
  filenames: `state_5.sqlite` and `logs_2.sqlite`.
  - Remove `STATE_DB_VERSION` / `LOGS_DB_VERSION` and the helper that
  constructed filenames from versions.
  - Stop `StateRuntime::init` from scanning for or deleting older SQLite
  DB filenames at startup.
  - Delete the tests that encoded legacy state/logs DB deletion behavior.
  
  ## Verification
  
  - `cargo test -p codex-state`

  ## Why
  
  Amazon Bedrock Mantle needs a stable client-agent header so requests

  ## What changed
  
  - Added `x-amzn-mantle-client-agent: codex` to the built-in Amazon
  Bedrock provider default HTTP headers.

• [daemon] Add app-server daemon lifecycle management (#20718)

  ## Why
  
  Desktop and mobile Codex clients need a machine-readable way to
  bootstrap and manage `codex app-server` on remote machines reached over
  SSH. The same flow is also useful for bringing up app-server with
  `remote_control` enabled on a fresh developer machine and keeping that
  managed install current without requiring a human session.
  
  ## What changed
  
  - add the new experimental `codex-app-server-daemon` crate and wire it
  into `codex app-server daemon` lifecycle commands: `start`, `restart`,
  `stop`, `version`, and `bootstrap`
  - add explicit `enable-remote-control` and `disable-remote-control`
  commands that persist the launch setting and restart a running managed
  daemon so the change takes effect immediately
  - emit JSON success responses for daemon commands so remote callers can
  consume them directly
  - support a Unix-only pidfile-backed detached backend for lifecycle
  management
  - assume the standalone `install.sh` layout for daemon-managed binaries
  and always launch `CODEX_HOME/packages/standalone/current/codex`
  - add bootstrap support for the standalone managed install plus a
  detached hourly updater loop
  - harden lifecycle management around concurrent operations, pidfile
  ownership, stale state cleanup, updater ownership, managed-binary
  preflight, Unix-only rejection, forced shutdown after the graceful
  window, and updater process-group tracking/cleanup
  - document the experimental Unix-only support boundary plus the
  standalone bootstrap/update flow in
  `codex-rs/app-server-daemon/README.md`
  
  ## Verification
  
  - `cargo test -p codex-app-server-daemon -p codex-cli`
  - live pid validation on `cb4`: `bootstrap --remote-control`, `restart`,
  `version`, `stop`
  
  ## Follow-up
  
  - Add updater self-refresh so the long-lived `pid-update-loop` can
  replace its own executable image after installing a newer managed Codex
  binary.

• Increase exec-server environment transport timeouts (#21825)

  ## Why
  
  The environment-backed exec-server transport currently hardcodes 5
  second connect and initialize timeouts in `client_transport.rs`. That is
  short for SSH-backed stdio environments and remote websocket
  environments, and there is currently no way to raise those values from
  `CODEX_HOME/environments.toml`.
  
  This stacked follow-up raises the default environment transport timeouts
  and lets each configured environment override them in
  `environments.toml`.
  
  ## What Changed
  
  - raise the default environment transport connect and initialize
  timeouts from 5s to 10s
  - store concrete timeout values on `ExecServerTransportParams` instead
  of hardcoding them in `connect_for_transport(...)`
  - add `connect_timeout_sec` and `initialize_timeout_sec` to
  `[[environments]]` entries in `environments.toml`
  - apply parse-time defaults so runtime transport code receives fully
  resolved timeout values
  - reject `connect_timeout_sec` on stdio environments because it only
  applies to websocket transports
  - extend parser tests to cover the new fields and defaults
  
  ## Stack
  
  - base: https://github.com/openai/codex/pull/21794
  - this PR: configurable environment transport timeouts
  
  ## Validation
  
  - `cd

• [codex] support executor registry remote environments (#21323)

  ## Summary
  
  Support registry-backed remote executors end to end so downstream
  services can resolve an executor id into an exec-server URL and make
  that environment available to Codex without relying on the legacy cloud
  environments flow.
  
  ## What changed
  
  - switch remote executor registration to the executor registry bootstrap
  contract
  - allow named remote environments to be inserted into
  `EnvironmentManager` at runtime
  - add the experimental app-server RPC `environment/add` so initialized
  experimental clients can register those remote environments for later
  `thread/start` and `turn/start` selection
  
  ## Validation
  
  Ran focused validation locally:
  - `cargo test -p codex-exec-server environment_manager_`
  - `cargo test -p codex-exec-server
  register_executor_posts_with_bearer_token_header`
  - `cargo test -p codex-app-server-protocol`

• app-server: support daemon-safe restart handling (#21831)

  ## Why
  
  The app-server daemon work needs two app-server behaviors to be safe
  when lifecycle management is driven by a helper process:
  
  - a readiness probe must not become the process-wide client identity
  just because it connects first
  - a graceful reload signal needs to keep draining active turns even if
  it is delivered more than once
  
  ## What changed
  
  - Treat `codex_app_server_daemon` initialization as a probe-only client
  for process-global originator and user-agent suffix state.
  - Distinguish forceable shutdown signals from graceful-only ones, and
  treat Unix `SIGHUP` as graceful-only while leaving `SIGTERM` and Ctrl-C
  forceable.
  - Add regression coverage for daemon probe initialization and repeated
  `SIGHUP` delivery while a turn is still running.
  
  ## Testing
  
  - `cargo test -p codex-app-server`
    - The new daemon-probe and repeated-`SIGHUP` coverage passed.
  - The run still failed in the existing
  `suite::conversation_summary::get_conversation_summary_by_relative_rollout_path_resolves_from_codex_home`
  and
  `suite::conversation_summary::get_conversation_summary_by_thread_id_reads_rollout`
  tests because their initialize handshake timed out.
  - `cargo test -p codex-app-server --test all
  suite::conversation_summary::`
  - Reproduced the same two existing initialize-timeout failures in
  isolation.

• ci: check out PR head commits in workflows (#21835)

  ## Why
  
  PR CI should test the exact commit that was pushed to the PR branch. By
  default, GitHub's `pull_request` event checks out a synthetic merge
  commit from `refs/pull/<number>/merge`, so the tested tree can include
  an implicit merge with the current base branch instead of matching the
  pushed head SHA.
  
  Using the PR head SHA makes each check result correspond to a concrete
  commit the author submitted. This also behaves better for stacked PR
  workflows, including Sapling stacks and other Git stack tooling: a
  middle PR's head commit already contains the lower stack changes in its
  tree, without pulling in commits above it or GitHub's temporary merge
  ref.
  
  ## What Changed
  
  - Set every `actions/checkout` in `pull_request` workflows under
  `.github/workflows` to use `github.event.pull_request.head.sha` on PR
  events and `github.sha` otherwise.
  - Updated `blob-size-policy` to compare
  `github.event.pull_request.base.sha` and
  `github.event.pull_request.head.sha`, since it no longer checks out
  GitHub's merge commit where `HEAD^1`/`HEAD^2` represented the PR range.
  
  ## Verification
  
  - Parsed the edited workflow YAML files with Ruby.
  - Checked that every checkout block in the `pull_request` workflows has
  the PR-head `ref`.

• Using cached connector directory for discoverable tools list (#21497)

  ## Summary
  
  Startup tool construction currently depends on connector directory
  metadata for `tool_suggest` discoverables. On a cold directory cache,
  that can put slow connector-directory requests on the blocking path even
  though the tools array only needs directory data for install
  suggestions, not for the live connector MCP tools themselves.
  
  This PR keeps the discoverables path off that cold network fetch:
  - read connector directory metadata from cache only when building
  discoverable tools
  - persist connector directory metadata to
  `~/.codex/cache/codex_app_directory/<hash>.json` and use it to hydrate
  the in-memory cache on later runs before the normal refresh path updates
  it
  - use connector-directory-specific cache naming to distinguish this
  metadata cache from the separate Codex Apps tools-spec cache
  
  This reduces first-turn startup work without changing how live connector
  MCP tools are sourced. Longer term, directory-backed install suggestions
  should move to a search-based flow so they no longer need to be inlined
  into the tools prompt at all.
  
  ## Testing
  
  - `cargo test -p codex-connectors`
  - `cargo test -p codex-chatgpt`
  - `cargo test -p codex-core
  request_plugin_install_is_available_without_search_tool_after_discovery_attempts`

• Enable --deny-warnings for cargo shear (#21616)

  ## Summary
  
  In https://github.com/openai/codex/pull/21584, we disabled doctests for
  crates that lack any doctests. We can enforce that property via `cargo
  shear --deny-warnings`: crates that lack doctests will be flagged if
  doctests are enabled, and crates with doctests will be flagged if
  doctests are disabled.
  
  A few additional notes:
  
  - By adding `--deny-warnings`, `cargo shear` also flagged a number of
  modules that were not reachable at all. Some of those have been removed.
  - This PR removes a usage of `windows_modules!` (since `cargo shear` and
  `rustfmt` couldn't see through it) in favor of simple `#[cfg(target_os =
  "windows")]` macros. As a consequence, many of these files exhibit churn
  in this PR, since they weren't being formatted by `rustfmt` at all on
  main.
  - Again, to make the code more analyzable, this PR also removes some
  usages of `#[path = "cwd_junction.rs"]` in favor of a more standard
  module structure. The bin sidecar structure is still retained, but,
  e.g., `windows-sandbox-rs/src/bin/command_runner.rs‎` was moved to
  `windows-sandbox-rs/src/bin/command_runner/main.rs`, and so on.

• [codex] Remove legacy after tool use hooks (#21805)

  ## Why
  
  The legacy `AfterToolUse` hook path was still wired through core tool
  dispatch even though the hooks registry never populated any handlers for
  it. The supported hook surface is `PostToolUse`, so the old
  infrastructure was dead code on the hot path.
  
  ## What changed
  
  - Removed the legacy `AfterToolUse` dispatch from `codex-core` tool
  execution.
  - Removed the unused legacy hook payload types and exports from
  `codex-hooks`.
  - Simplified legacy notify handling now that `HookEvent` only carries
  `AfterAgent`.

• [codex] Delete function-style apply_patch (#21651)

  ## Why
  
  `apply_patch` is now a freeform/custom tool. Keeping the old
  JSON/function-style registration and parsing path left another way for
  models and tests to invoke `apply_patch`, which made the tool surface
  harder to reason about.
  
  ## What changed
  
  - Removed the `ApplyPatchToolType::Function` variant, JSON `apply_patch`
  spec, and handler support for function payloads.
  - Kept `apply_patch_tool_type = freeform` as the supported model
  metadata path, including Bedrock catalog metadata.
  - Migrated `apply_patch` tests and SSE fixtures to custom/freeform tool
  calls.

• [codex] request desktop attestation from app (#20619)

  ## Summary
  
  TL;DR: teaches `codex-rs` / app-server to request a desktop-provided
  attestation token and attach it as `x-oai-attestation` on the scoped
  ChatGPT Codex request paths.
  
  ![DeviceCheck attestation
  interface](https://raw.githubusercontent.com/openai/codex/dev/jm/devicecheck-diagram-assets/pr-assets/devicecheck-attestation-interface.png)
  
  ## Details
  
  This PR teaches the Codex app-server runtime how to request and attach
  an attestation token. It does not generate DeviceCheck tokens directly;
  instead, it relies on the connected desktop app to advertise that it can
  generate attestation and then asks that app for a fresh header value
  when needed.
  
  The flow is:
  
  1. The Codex desktop app connects to app-server.
  2. During `initialize`, the app can advertise that it supports
  `requestAttestation`.
  3. Before app-server calls selected ChatGPT Codex endpoints, it sends
  the internal server request `attestation/generate` to the app.
  4. app-server receives a pre-encoded header value back.
  5. app-server forwards that value as `x-oai-attestation` on the scoped
  outbound requests.
  
  The code in this repo is mostly protocol and runtime plumbing: it adds
  the app-server request/response shape, introduces an attestation
  provider in core, wires that provider into Responses / compaction /
  realtime setup paths, and covers the intended scoping with tests. The
  signed macOS DeviceCheck generation remains owned by the desktop app PR.
  
  ## Related PR
  
  - Codex desktop app implementation:

  <summary>E2E DeviceCheck validation</summary>
  
  First validated the signed desktop app boundary directly: launched a
  packaged signed `Codex.app`, sent `attestation/generate`, decoded the
  returned `v1.` attestation header, and validated the extracted
  DeviceCheck token with `personal/jm/verify_devicecheck_token.py` using
  bundle ID `com.openai.codex`. Apple returned `status_code: 200` and
  `is_ok: true`.
  
  Then ran the fuller app + app-server flow. The packaged `Codex.app`
  launched a current-branch app-server via `CODEX_CLI_PATH`, and a local
  MITM proxy intercepted outbound `chatgpt.com` traffic. The app-server
  requested `attestation/generate` from the real Electron app process, and
  the intercepted `/backend-api/codex/responses` traffic included
  `x-oai-attestation` on both routes:
  
  ```text
  GET  /backend-api/codex/responses  Upgrade: websocket  x-oai-attestation: present
  POST /backend-api/codex/responses  Upgrade: none       x-oai-attestation: present
  ```
  
  The captured header decoded to a DeviceCheck token that also validated
  with Apple for `com.openai.codex` (`status_code: 200`, `is_ok: true`,
  team `2DC432GLL2`).

• Remove ToolName display helper (#21465)

  ## Why
  
  `ToolName::display()` made it too easy to flatten tool identity and
  accidentally compare rendered strings. Tool identity should stay
  structural until a legacy string boundary actually requires the
  flattened spelling.
  
  ## What
  
  - Removes `ToolName::display()` and relies on the existing `Display`
  impl for messages and errors.
  - Adds structural ordering for `ToolName` and uses it for
  sorting/deduping deferred tools.
  - Carries `ToolName` through tool/sandbox plumbing, flattening only at
  legacy boundaries such as hook payloads, telemetry tags, and Responses
  tool names.
  - Updates MCP normalization tests to assert `ToolName` structure instead
  of rendered strings.
  
  ## Testing
  
  - `cargo test -p codex-mcp test_normalize_tools`
  - `cargo test -p codex-core unavailable_tool`
  - `just fix -p codex-protocol`

• Emit accepted line fingerprint analytics (#21601)

  ## Why
  
  Codex assisted-code attribution needs a client-side accepted-code source
  that does not upload raw code. This adds a hash-only analytics event
  derived from the turn diff so downstream attribution can compare
  accepted Codex lines against commit or PR diffs.
  
  ## What Changed
  
  - Parse accepted/effective added lines from the final turn diff and emit
  `codex_accepted_line_fingerprints` analytics.
  - Hash repo, path, and normalized line content before upload; raw code
  and raw diffs are not included in the event.
  - Chunk large fingerprint payloads and send accepted-line fingerprint
  events in isolated requests while preserving normal batching for other
  analytics events.
  - Canonicalize Git remote URLs before repo hashing so SSH/HTTPS GitHub
  remotes join to the same repo hash.
  - Add parser coverage for unified diff hunk lines that look like `+++`
  or `---` file headers.

• Publish Python runtime wheels on release (#21784)

  ## Why
  
  Published Python SDK builds depend on an exact `openai-codex-cli-bin`
  runtime package, but the release workflow did not publish that runtime
  package to PyPI. That left the SDK packaging story incomplete: release
  artifacts could produce Codex binaries, but Python users still needed a
  matching wheel carrying the platform-specific runtime and helper
  executables.
  
  This PR is stacked on #21787 so release jobs can include helper binaries
  in runtime wheels: Linux wheels include `bwrap` for sandbox fallback,
  and Windows wheels include the signed sandbox/elevation helpers beside
  `codex.exe`.
  
  ## What changed
  
  - Builds platform-specific `openai-codex-cli-bin` wheels from signed
  release binaries on macOS, Linux, and Windows release runners.
  - Packages Linux `bwrap` into musllinux runtime wheels.
  - Packages Windows sandbox helper executables into Windows runtime
  wheels.
  - Uploads runtime wheels as GitHub release assets and publishes them to
  PyPI using trusted publishing from the `pypi` GitHub environment.
  - Keeps the new Python runtime publish job non-blocking so failures need
  follow-up but do not fail the Rust release workflow.
  - Pins the PyPA publish action to the `v1.13.0` commit SHA for
  reproducible release publishing.
  - Documents that runtime wheels are platform wheels published through
  PyPI trusted publishing.
  
  ## Testing
  
  - `ruby -e 'require "yaml"; ARGV.each { |f| YAML.load_file(f); puts "ok
  #{f}" }' .github/workflows/rust-release.yml
  .github/workflows/rust-release-windows.yml`
  - `git diff --check`
  
  CI is the real end-to-end verification for the release workflow path.

• Support resource binaries in Python runtime staging (#21787)

  ## Why
  
  Some Codex runtime distributions need helper executables beside the main
  bundled binary. Linux sandbox fallback needs a packaged `bwrap` when no
  suitable system `bwrap` is available, and Windows sandbox/elevation
  needs helper executables discoverable beside `codex.exe`. The checked-in
  `openai-codex-cli-bin` template already packages everything under
  `codex_cli_bin/bin/**`, but the staging script only copied the main
  Codex binary into that directory.
  
  This PR adds the generic staging primitive needed by release workflows
  to build complete platform runtime wheels without baking
  platform-specific helper names into the package template.
  
  ## What changed
  
  - Added repeatable `stage-runtime --resource-binary` support so release
  workflows can copy extra executables beside the bundled Codex binary.
  - Kept resource selection in workflow code, where the platform target is
  known.
  - Added tests that verify resource binaries are copied into the staged
  runtime package, that the wheel include config covers them, and that the
  CLI forwards repeated `--resource-binary` values.
  
  ## Testing
  
  - `uv run ruff check scripts/update_sdk_artifacts.py
  tests/test_artifact_workflow_and_binaries.py`
  - `uv run --extra dev pytest
  tests/test_artifact_workflow_and_binaries.py::test_stage_runtime_release_copies_resource_binaries
  tests/test_artifact_workflow_and_binaries.py::test_runtime_resource_binaries_are_included_by_wheel_config
  tests/test_artifact_workflow_and_binaries.py::test_stage_runtime_stages_binary_without_type_generation`
  
  Full `tests/test_artifact_workflow_and_binaries.py` still has unrelated
  schema-normalization drift in the local checkout.

• Load configured environments from CODEX_HOME (#20667)

  ## Why
  
  The earlier PRs add stdio transport support and the config-backed
  environment provider, but the feature remains inert until normal Codex
  entrypoints construct `EnvironmentManager` with enough context to
  discover `CODEX_HOME/environments.toml`. This final stack PR activates
  the provider while preserving the legacy `CODEX_EXEC_SERVER_URL`
  fallback when no environments file exists.
  
  **Stack position:** this is PR 5 of 5. It is the product wiring PR that
  activates the configured environment provider added in PR 4.
  
  ## What Changed
  
  - Thread `codex_home` into `EnvironmentManagerArgs`.
  - Change `EnvironmentManager::new(...)` to load the provider from
  `CODEX_HOME`.
  - Preserve legacy behavior by falling back to
  `DefaultEnvironmentProvider::from_env()` when `environments.toml` is
  absent.
  - Make `environments.toml`-backed managers start new threads with all
  configured environments, default first, while keeping the legacy env-var
  path single-default.
  - Update the app-server, TUI, exec, MCP server, connector, prompt-debug,
  and thread-manager-sample callsites to pass `codex_home` and handle
  provider-loading errors.
  
  ## Self-Review Notes
  
  - The multi-environment startup path is intentionally tied to the
  `environments.toml` provider. Using `>1` configured environment as the
  only signal would also expand the legacy `CODEX_EXEC_SERVER_URL`
  provider because it keeps `local` addressable alongside `remote`.
  - The startup environment list is still derived inside
  `EnvironmentManager`; the provider only says whether its snapshot should
  start new threads with all configured environments.
  - The thread-manager sample was updated to pass the current
  `ThreadManager::new(...)` installation id argument so the stack compiles
  under Bazel.
  
  ## Stack
  
  - 1. https://github.com/openai/codex/pull/20663 - Add stdio exec-server
  listener
  - 2. https://github.com/openai/codex/pull/20664 - Add stdio exec-server

  ## Documentation
  
  This activates `CODEX_HOME/environments.toml`; user-facing documentation
  should be added before this stack is treated as a documented public
  workflow.

• [codex] Address some more GHA hygiene issues (#21622)

  This does two things:
  
  - We use `persist-credentials: false` everywhere now. This is
  unfortunately not the default in GitHub Actions, but it prevents
  `actions/checkout` from dropping `secrets.GITHUB_TOKEN` onto disk.
  - We interpose (some) template expansions through environment variables.
  I've limited this to contexts that have non-fixed values; contexts that
  are fixed (like `*.result`) are not dangerous to expand directly inline
  (but maybe we should clean those up in the future for consistency
  anyways).
  
  This is a medium-risk change in terms of CI breakage: I did a scan for
  usage of `git push` and other commands that implicitly use the persisted
  credential, but couldn't find any. Even still, some implicit usages of
  the persisted credentials may be lurking. Please ping ww@ if any issues
  arise.

• Clarify docs folder guidance in AGENTS.md (#21772)

  ## Summary
  
  Codex keeps trying to add documentation to the `docs/` directory. With
  the exception of app server API documentation, the docs for Codex should
  not live in this repo. We don't want the local `docs/` folder to become
  a stale shadow of the official docs.
  
  This PR updates `AGENTS.md` to make that boundary explicit and scopes
  the existing API documentation guidance to app-server docs/examples. It
  also removes the extra `docs/config.md` sections that were recently
  added.

• [codex] Generalize service tier slash commands (#21745)

  ## Why
  
  `/fast` was wired as a one-off slash command even though model metadata
  now exposes service tiers as catalog data. That meant adding another
  tier, such as a slower/cheaper tier, would require more hardcoded TUI
  plumbing instead of letting the model catalog drive the available
  commands.
  
  This change makes service-tier commands data-driven: each advertised
  `service_tiers` entry becomes a `/name` command using the catalog
  description, while the request path sends the tier `id` only when the
  selected model supports it.
  
  ## What Changed
  
  - Removed the hardcoded `/fast` slash-command variant and introduced
  dynamic service-tier command items in the composer and command popup.
  - Added toggle behavior for service-tier commands: invoking `/name`
  selects that tier, and invoking it again clears the selection.
  - Preserved the existing Fast-mode keybinding/status affordances by
  resolving the current model tier whose name is `fast`, while still
  sending the tier request value such as `priority`.
  - Persisted service-tier selections as raw request strings so non-fast
  tiers can round-trip through config.
  - Updated the Bedrock catalog entry to advertise fast support through
  `service_tiers` with `id: "priority"` and `name: "fast"`.
  - Added defensive filtering in core so unsupported selected service
  tiers are omitted from `/responses` requests.
  
  ## Validation
  
  - Added/updated coverage for dynamic service-tier slash command lookup,
  popup descriptions, composer dispatch, TUI fast toggling, and
  unsupported-tier omission in core request construction.
  - Local tests were not run per request.

• Use CARGO_NET_GIT_FETCH_WITH_CLI in rust-ci-full for more reliable git fetches (#21628)

  always call out to the git CLI because it is much more reliable. This is
  a part of my attempt to reduce flakes in `rust-ci-full`.

• Fix rust-ci-full failures due to missing bwrap (#21604)

  Since https://github.com/openai/codex/pull/21255, `rust-ci-full` has
  been failing due to a missing `bwrap`.
  
  ```
  thread 'main' panicked at linux-sandbox/src/launcher.rs:43:13:
  bubblewrap is unavailable: no system bwrap was found on PATH and no bundled codex-resources/bwrap binary was found next to the Codex executable
  ```
  
  Since the happy path is now to use the system binary, let's ensure
  that's installed.
  
  
  https://github.com/openai/codex/pull/21604/commits/8d5182663158ee2d15965f39eed26ffa339ecb7d
  was necessary for the `bwrap` executable to be discoverable when the
  working directory is `/`.

• [sandboxing] Remove Darwin user cache write from Seatbelt network policy (#21443)

  ## Summary
  
  1. Removes the broad `DARWIN_USER_CACHE_DIR` write rule from the macOS
  Seatbelt network policy.
  2. Removes the now unused policy parameter plumbing for that cache path.
  3. Adds sandboxing coverage that keeps `com.apple.trustd.agent` for TLS
  while rejecting the cache write rule.
  
  ## Why
  
  This closes the exact cache poisoning boundary. The earlier `gh` TLS
  issue is now covered by trustd access, so the cache write is no longer
  needed.
  
  ## Validation
  
  1. Rust formatting passed.
  2. The sandboxing crate tests passed.
  3. Local macOS Seatbelt repro with patched policy passed. `gh api`
  returned `21442` without the cache write rule.

  Provider initialization installs process-global OTEL state, so invalid

  Use the same span attribute validator as config loading when traces are

• api: send hyphenated session and thread headers (#21757)

  ## Why
  Some consumers expect conventional hyphenated HTTP headers. Codex
  already sends the session and thread IDs on outbound Responses requests,
  but it only uses the underscore spellings today, which makes those IDs
  harder to consume in systems that normalize or reject underscore header
  names.
  
  Full context here:
  https://openai.slack.com/archives/C08KCGLSPSQ/p1778248578422369
  
  ## What changed
  - `build_session_headers` now emits both `session_id` and `session-id`
  when a session ID is present.
  - It does the same for `thread_id` and `thread-id`.
  - Added regression coverage in `codex-api/tests/clients.rs` and
  `core/tests/suite/client.rs` so both the lower-level client tests and
  the end-to-end request tests assert the two header spellings are
  present.
  
  ## Test plan
  - Added header assertions in `codex-api/tests/clients.rs`.
  - Added request-header assertions in `core/tests/suite/client.rs` for
  both the `/v1/responses` and `/api/codex/responses` request paths.
