• tui: carry permission profiles on user turns (#18285)

  ## Why
  
  Per-turn permission overrides should use the same canonical profile
  abstraction as session configuration. That lets TUI submissions preserve
  exact configured permissions without round-tripping through legacy
  sandbox fields.
  
  ## What changed
  
  This adds `permission_profile` to user-turn operations, threads it
  through TUI/app-server submission paths, fills the new field in existing
  test fixtures, and adds coverage that composer submission includes the
  configured profile.
  
  ## Verification
  
  - `cargo test -p codex-tui permissions -- --nocapture`
  - `cargo test -p codex-core --test all permissions_messages --
  --nocapture`

• protocol: report session permission profiles (#18282)

  ## Why
  
  Clients that observe `SessionConfigured` need the same canonical
  permission view that app-server thread responses provide. Reporting the
  profile in protocol events lets clients keep their local state
  synchronized without reinterpreting legacy sandbox fields.
  
  ## What changed
  
  This adds `permission_profile` to `SessionConfigured` and propagates it
  through core, exec JSON output, MCP server messages, and TUI
  history/widget handling.
  
  ## Verification
  
  - `cargo test -p codex-tui permissions -- --nocapture`
  - `cargo test -p codex-core --test all permissions_messages --
  --nocapture`

• rollout: persist turn permission profiles (#18281)

  ## Why
  
  Resume and reconstruction need to preserve the permissions that were
  active for each user turn. If rollouts only keep legacy sandbox fields,
  replay cannot faithfully represent profile-shaped overrides introduced
  earlier in the stack.
  
  ## What changed
  
  This records `permission_profile` on user-turn rollout events,
  reconstructs it through history/state extraction, and updates rollout
  reconstruction and related fixtures to keep the field explicit.
  
  ## Verification
  
  - `cargo test -p codex-core --test all permissions_messages --
  --nocapture`
  - `cargo test -p codex-core --test all request_permissions --
  --nocapture`

• app-server: accept permission profile overrides (#18279)

  ## Why
  
  `PermissionProfile` is becoming the canonical permissions shape shared
  by core and app-server. After app-server responses expose the active
  profile, clients need to be able to send that same shape back when
  starting, resuming, forking, or overriding a turn instead of translating
  through the legacy `sandbox`/`sandboxPolicy` shorthands.
  
  This still needs to preserve the existing requirements/platform
  enforcement model. A profile-shaped request can be downgraded or
  rejected by constraints, but the server should keep the user's
  elevated-access intent for project trust decisions. Turn-level profile
  overrides also need to retain existing read protections, including
  deny-read entries and bounded glob-scan metadata, so a permission
  override cannot accidentally drop configured protections such as
  `**/*.env = deny`.
  
  ## What changed
  
  - Adds optional `permissionProfile` request fields to `thread/start`,
  `thread/resume`, `thread/fork`, and `turn/start`.
  - Rejects ambiguous requests that specify both `permissionProfile` and
  the legacy `sandbox`/`sandboxPolicy` fields, including running-thread
  resume requests.
  - Converts profile-shaped overrides into core runtime filesystem/network
  permissions while continuing to derive the constrained legacy sandbox
  projection used by existing execution paths.
  - Preserves project-trust intent for profile overrides that are
  equivalent to workspace-write or full-access sandbox requests.
  - Preserves existing deny-read entries and `globScanMaxDepth` when
  applying turn-level `permissionProfile` overrides.
  - Updates app-server docs plus generated JSON/TypeScript schema fixtures
  and regression coverage.
  
  ## Verification
  
  - `cargo test -p codex-app-server-protocol schema_fixtures`
  - `cargo test -p codex-core
  session_configuration_apply_permission_profile_preserves_existing_deny_read_entries`

• Add plumbing to approve stored Auto-Review denials (#18955)

  ## Summary
  
  This adds the structural plumbing needed for an app-server client to
  approve a previously denied Guardian review and carry that approval
  context into the next model turn.
  
  This PR does not add the actual `/auto-review-denials` tool 
  
  ## What Changed
  
  - Added app-server v2 RPC `thread/approveGuardianDeniedAction`.
  - Added generated JSON schema and TypeScript fixtures for
  `ThreadApproveGuardianDeniedAction*`.
  - Added core `Op::ApproveGuardianDeniedAction`.
  - Added a core handler that validates the event is a denied Guardian
  assessment and injects a developer message containing the stored denial
  event JSON.
  - Queues the approval context for the next turn if there is no active
  turn yet.
  - Added the TUI app-server bridge so `Op::ApproveGuardianDeniedAction {
  event }` is routed to the app-server request.
  
  ## What This Does Not Do
  
  - Does not add `/auto-review-denials`.
  - Does not add chat widget recent-denial state.
  - Does not add popup/list UI.
  - Does not add a product-facing denial lookup/store.
  - Does not change where Guardian denials are originally emitted or
  persisted.
  
  ## Verification
  
  - `cargo test -p codex-tui thread_approve_guardian_denied_action`

• [codex-analytics] guardian review TTFT plumbing and emission (#17696)

  ## Why
  
  Guardian analytics includes time-to-first-token, but the Guardian
  reviewer runs as a normal Codex session and `TurnCompleteEvent` did not
  expose TTFT. The timing needs to flow through the standard
  turn-completion protocol so Guardian review analytics can consume the
  same value as the rest of the session machinery.
  
  ## What changed
  
  Adds optional `time_to_first_token_ms` to `TurnCompleteEvent` and
  populates it from `TurnTiming`. The value is carried through app-server
  thread history, rollout reconstruction, TUI/app-server adapters, and
  Guardian review session handling.
  
  Guardian review analytics now captures TTFT from the reviewer
  turn-complete event when available. Existing tests and fixtures are
  updated to set the new optional field to `None` where TTFT is not
  relevant.
  
  ## Verification
  
  - `cargo clippy -p codex-tui --tests -- -D warnings`
  - `cargo clippy -p codex-core --lib --tests -- -D warnings`

• fix: fully revert agent identity runtime wiring (#18757)

  ## Summary
  
  This PR fully reverts the previously merged Agent Identity runtime
  integration from the old stack:
  https://github.com/openai/codex/pull/17387/changes
  
  It removes the Codex-side task lifecycle wiring, rollout/session
  persistence, feature flag plumbing, lazy `auth.json` mutation,
  background task auth paths, and request callsite changes introduced by
  that stack.
  
  This leaves the repo in a clean pre-AgentIdentity integration state so
  the follow-up PRs can reintroduce the pieces in smaller reviewable
  layers.
  
  ## Stack
  
  1. This PR: full revert
  2. https://github.com/openai/codex/pull/18871: move Agent Identity
  business logic into a crate
  3. https://github.com/openai/codex/pull/18785: add explicit
  AgentIdentity auth mode and startup task allocation
  4. https://github.com/openai/codex/pull/18811: migrate auth callsites
  through AuthProvider
  
  ## Testing
  
  Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.

• [tool search] support namespaced deferred dynamic tools (#18413)

  Deferred dynamic tools need to round-trip a namespace so a tool returned
  by `tool_search` can be called through the same registry key that core
  uses for dispatch.
  
  This change adds namespace support for dynamic tool specs/calls,
  persists it through app-server thread state, and routes dynamic tool
  calls by full `ToolName` while still sending the app the leaf tool name.
  Deferred dynamic tools must provide a namespace; non-deferred dynamic
  tools may remain top-level.
  
  It also introduces `LoadableToolSpec` as the shared
  function-or-namespace Responses shape used by both `tool_search` output
  and dynamic tool registration, so dynamic tools use the same wrapping
  logic in both paths.
  
  Validation:
  - `cargo test -p codex-tools`
  - `cargo test -p codex-core tool_search`

• Add realtime silence tool (#18635)

  ## Summary
  
  Adds a second realtime v2 function tool, `remain_silent`, so the
  realtime model has an explicit non-speaking action when the
  collaboration mode or latest context says it should not answer aloud.
  This is stacked on #18597.
  
  ## Design
  
  - Advertise `remain_silent` alongside `background_agent` in realtime v2
  conversational sessions.
  - Parse `remain_silent` function calls into a typed
  `RealtimeEvent::NoopRequested` event.
  - Have core answer that function call with an empty
  `function_call_output` and deliberately avoid `response.create`, so no
  follow-up realtime response is requested.
  - Keep the event hidden from app-server/TUI surfaces; it is operational
  plumbing, not user-visible conversation content.

• [codex-analytics] guardian review analytics schema polishing (#17692)

  ## Why
  
  Guardian review analytics needs a Rust event shape that matches the
  backend schema while avoiding unnecessary PII exposure from reviewed
  tool calls. This PR narrows the analytics payload to the fields we
  intend to emit and keeps shared Guardian assessment enums in protocol
  instead of duplicating equivalent analytics-only enums.
  
  ## What changed
  
  - Uses protocol Guardian enums directly for `risk_level`,
  `user_authorization`, `outcome`, and command source values.
  - Removes high-risk reviewed-action fields from the analytics payload,
  including raw commands, display strings, working directories, file
  paths, network targets/hosts, justification text, retry reason, and
  rationale text.
  - Makes `target_item_id` and `tool_call_count` nullable so the Codex
  event can represent cases where the app-server protocol or producer does
  not have those values.
  - Keeps lower-risk structured reviewed-action metadata such as sandbox
  permissions, permission profile, `tty`, `execve` source/program, network
  protocol/port, and MCP connector/tool labels.
  - Adds an analytics reducer/client test covering `codex_guardian_review`
  serialization with an optional `target_item_id` and absent removed
  fields.
  
  ## Verification
  
  - `cargo test -p codex-analytics
  guardian_review_event_ingests_custom_fact_with_optional_target_item`
  - `cargo fmt --check`

• Add PermissionRequest hooks support (#17563)

  ## Why
  
  We need `PermissionRequest` hook support!
  
  Also addresses:
  - https://github.com/openai/codex/issues/16301
  - run a script on Hook to do things like play a sound to draw attention
  but actually no-op so user can still approve
  - can omit the `decision` object from output or just have the script
  exit 0 and print nothing
  - https://github.com/openai/codex/issues/15311
    - let the script approve/deny on its own
    - external UI what will run on Hook and relay decision back to codex
  
  
  ## Reviewer Note
  
  There's a lot of plumbing for the new hook, key files to review are:
  - New hook added in `codex-rs/hooks/src/events/permission_request.rs`
  - Wiring for network approvals
  `codex-rs/core/src/tools/network_approval.rs`
  - Wiring for tool orchestrator `codex-rs/core/src/tools/orchestrator.rs`
  - Wiring for execve
  `codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs`
  
  ## What
  
  - Wires shell, unified exec, and network approval prompts into the
  `PermissionRequest` hook flow.
  - Lets hooks allow or deny approval prompts; quiet or invalid hooks fall
  back to the normal approval path.
  - Uses `tool_input.description` for user-facing context when it helps:
    - shell / `exec_command`: the request justification, when present
    - network approvals: `network-access <domain>`
  - Uses `tool_name: Bash` for shell, unified exec, and network approval
  permission-request hooks.
  - For network approvals, passes the originating command in
  `tool_input.command` when there is a single owning call; otherwise falls
  back to the synthetic `network-access ...` command.

  Basically in `from_absolute_path` there is a `absolutize::absolutize`
  that calls a `current_dir()` . But the dir in which Codex was running
  got re-generated (because of Codex I guess but I can't exactly see the
  source). So `current_dir()` returns an `ENOENT` and 💥

• [codex-analytics] add session source to client metadata (#17374)

  ## Summary
  
  Adds `thread_source` field to the existing Codex turn metadata sent to
  Responses API
  - Sends `thread_source: "user"` for user-initiated sessions: CLI, VS
  Code, and Exec
  - Sends `thread_source: "subagent"` for subagent sessions
  - Omits `thread_source` for MCP, custom, and unknown session sources
  - Uses the existing turn metadata transport:
    - HTTP requests send through the `x-codex-turn-metadata` header
  - WebSocket `response.create` requests send through
  `client_metadata["x-codex-turn-metadata"]`
  
  ## Testing
  - `cargo test -p codex-protocol
  session_source_thread_source_name_classifies_user_and_subagent_sources`
  - `cargo test -p codex-core turn_metadata_state`
  - `cargo test -p codex-core --test responses_headers

• representing guardian review timeouts in protocol types (#17381)

  ## Summary
  
  - Add `TimedOut` to Guardian/review carrier types:
    - `ReviewDecision::TimedOut`
    - `GuardianAssessmentStatus::TimedOut`
    - app-server v2 `GuardianApprovalReviewStatus::TimedOut`
  - Regenerate app-server JSON/TypeScript schemas for the new wire shape.
  - Wire the new status through core/app-server/TUI mappings with
  conservative fail-closed handling.
  - Keep `TimedOut` non-user-selectable in the approval UI.
  
  **Does not change runtime behavior yet; emitting `TimeOut` and
  parent-model timeout messaging will come in followup PRs**

• fix(permissions): fix symlinked writable roots in sandbox permissions (#15981)

  ## Summary
  - preserve logical symlink paths during permission normalization and
  config cwd handling
  - bind real targets for symlinked readable/writable roots in bwrap and
  remap carveouts and unreadable roots there
  - add regressions for symlinked carveouts and nested symlink escape
  masking
  
  ## Root cause
  Permission normalization canonicalized symlinked writable roots and cwd
  to their real targets too early. That drifted policy checks away from
  the logical paths the sandboxed process can actually address, while
  bwrap still needed the real targets for mounts. The mismatch caused
  shell and apply_patch failures on symlinked writable roots.
  
  ## Impact
  Fixes #15781.
  
  Also fixes #17079:
  - #17079 is the protected symlinked carveout side: bwrap now binds the
  real symlinked writable-root target and remaps carveouts before masking.
  
  Related to #15157:
  - #15157 is the broader permission-check side of this path-identity
  problem. This PR addresses the shared logical-vs-canonical normalization
  issue, but the reported Darwin prompt behavior should be validated
  separately before auto-closing it.
  
  This should also fix #14672, #14694, #14715, and #15725:
  - #14672, #14694, and #14715 are the same Linux
  symlinked-writable-root/bwrap family as #15781.
  - #15725 is the protected symlinked workspace path variant; the PR
  preserves the protected logical path in policy space while bwrap applies
  read-only or unreadable treatment to the resolved target so
  file-vs-directory bind mismatches do not abort sandbox setup.
  
  ## Notes
  - Added Linux-only regressions for symlinked writable ancestors and
  protected symlinked directory targets, including nested symlink escape
  masking without rebinding the escape target writable.

• fix(guardian, app-server): introduce guardian review ids (#17298)

  ## Description
  
  This PR introduces `review_id` as the stable identifier for guardian
  reviews and exposes it in app-server `item/autoApprovalReview/started`
  and `item/autoApprovalReview/completed` events.
  
  Internally, guardian rejection state is now keyed by `review_id` instead
  of the reviewed tool item ID. `target_item_id` is still included when a
  review maps to a concrete thread item, but it is no longer overloaded as
  the review lifecycle identifier.
  
  ## Motivation
  
  We'd like to give users the ability to preempt a guardian review while
  it's running (approve or decline).
  
  However, we can't implement the API that allows the user to override a
  running guardian review because we didn't have a unique `review_id` per
  guardian review. Using `target_item_id` is not correct since:
  - with execve reviews, there can be multiple execve calls (and therefore
  guardian reviews) per shell command
  - with network policy reviews, there is no target item ID
  
  The PR that actually implements user overrides will use `review_id` as
  the stable identifier.

• Support clear SessionStart source (#17073)

  ## Motivation
  
  The `SessionStart` hook already receives `startup` and `resume` sources,
  but sessions created from `/clear` previously looked like normal startup
  sessions. This makes it impossible for hook authors to distinguish
  between these with the matcher.
  
  ## Summary
  
  - Add `InitialHistory::Cleared` so `/clear`-created sessions can be
  distinguished from ordinary startup sessions.
  - Add `SessionStartSource::Clear` and wire it through core, app-server
  thread start params, and TUI clear-session flow.
  - Update app-server protocol schemas, generated TypeScript, docs, and
  related tests.

• 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.

• Forward app-server turn clientMetadata to Responses (#16009)

  ## Summary
  App-server v2 already receives turn-scoped `clientMetadata`, but the
  Rust app-server was dropping it before the outbound Responses request.
  This change keeps the fix lightweight by threading that metadata through
  the existing turn-metadata path rather than inventing a new transport.
  
  ## What we're trying to do and why
  We want turn-scoped metadata from the app-server protocol layer,
  especially fields like Hermes/GAAS run IDs, to survive all the way to
  the actual Responses API request so it is visible in downstream
  websocket request logging and analytics.
  
  The specific bug was:
  - app-server protocol uses camelCase `clientMetadata`
  - Responses transport already has an existing turn metadata carrier:
  `x-codex-turn-metadata`
  - websocket transport already rewrites that header into
  `request.request_body.client_metadata["x-codex-turn-metadata"]`
  - but the Rust app-server never parsed or stored `clientMetadata`, so
  nothing from the app-server request was making it into that existing
  path
  
  This PR fixes that without adding a new header or a second metadata
  channel.
  
  ## How we did it
  ### Protocol surface
  - Add optional `clientMetadata` to v2 `TurnStartParams` and
  `TurnSteerParams`
  - Regenerate the JSON schema / TypeScript fixtures
  - Update app-server docs to describe the field and its behavior
  
  ### Runtime plumbing
  - Add a dedicated core op for app-server user input carrying turn-scoped
  metadata: `Op::UserInputWithClientMetadata`
  - Wire `turn/start` and `turn/steer` through that op / signature path
  instead of dropping the metadata at the message-processor boundary
  - Store the metadata in `TurnMetadataState`
  
  ### Transport behavior
  - Reuse the existing serialized `x-codex-turn-metadata` payload
  - Merge the new app-server `clientMetadata` into that JSON additively
  - Do **not** replace built-in reserved fields already present in the
  turn metadata payload
  - Keep websocket behavior unchanged at the outer shape level: it still
  sends only `client_metadata["x-codex-turn-metadata"]`, but that JSON
  string now contains the merged fields
  - Keep HTTP fallback behavior unchanged except that the existing
  `x-codex-turn-metadata` header now includes the merged fields too
  
  ### Request shape before / after
  Before, a websocket `response.create` looked like:
  ```json
  {
    "type": "response.create",
    "client_metadata": {
      "x-codex-turn-metadata": "{\"session_id\":\"...\",\"turn_id\":\"...\"}"
    }
  }
  ```
  Even if the app-server caller supplied `clientMetadata`, it was not
  represented there.
  
  After, the same request shape is preserved, but the serialized payload
  now includes the new turn-scoped fields:
  ```json
  {
    "type": "response.create",
    "client_metadata": {
      "x-codex-turn-metadata": "{\"session_id\":\"...\",\"turn_id\":\"...\",\"fiber_run_id\":\"fiber-start-123\",\"origin\":\"gaas\"}"
    }
  }
  ```
  
  ## Validation
  ### Targeted tests added / updated
  - protocol round-trip coverage for `clientMetadata` on `turn/start` and
  `turn/steer`
  - protocol round-trip coverage for `Op::UserInputWithClientMetadata`
  - `TurnMetadataState` merge test proving client metadata is added
  without overwriting reserved built-in fields
  - websocket request-shape test proving outbound `response.create`
  contains merged metadata inside
  `client_metadata["x-codex-turn-metadata"]`
  - app-server integration tests proving:
  - `turn/start` forwards `clientMetadata` into the outbound Responses
  request path
    - websocket warmup + real turn request both behave correctly
    - `turn/steer` updates the follow-up request metadata
  
  ### Commands run
  - `just write-app-server-schema`
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-protocol`
  - `cargo test -p codex-core
  turn_metadata_state_merges_client_metadata_without_replacing_reserved_fields
  --lib`
  - `cargo test -p codex-core --test all
  responses_websocket_preserves_custom_turn_metadata_fields`
  - `cargo test -p codex-app-server --test all client_metadata`
  - `cargo test -p codex-app-server --test all
  turn_start_forwards_client_metadata_to_responses_websocket_request_body_v2

  - `just fmt`
  - `just fix -p codex-core -p codex-protocol -p codex-app-server-protocol
  -p codex-app-server`
  - `just fix -p codex-exec -p codex-tui-app-server`
  - `just argument-comment-lint`
  
  ### Full suite note
  `cargo test` in `codex-rs` still fails in:
  -
  `suite::v2::turn_interrupt::turn_interrupt_resolves_pending_command_approval_request`
  
  I verified that same failure on a clean detached `HEAD` worktree with an
  isolated `CARGO_TARGET_DIR`, so it is not caused by this patch.

• fix(guardian): make GuardianAssessmentEvent.action strongly typed (#16448)

  ## Description
  
  Previously the `action` field on `EventMsg::GuardianAssessment`, which
  describes what Guardian is reviewing, was typed as an arbitrary JSON
  blob. This PR cleans it up and defines a sum type representing all the
  various actions that Guardian can review.
  
  This is a breaking change (on purpose), which is fine because:
  - the Codex app / VSCE does not actually use `action` at the moment
  - the TUI code that consumes `action` is updated in this PR as well
  - rollout files that serialized old `EventMsg::GuardianAssessment` will
  just silently drop these guardian events
  - the contract is defined as unstable, so other clients have a fair
  warning :)
  
  This will make things much easier for followup Guardian work.
  
  ## Why
  
  The old guardian review payloads worked, but they pushed too much shape
  knowledge into downstream consumers. The TUI had custom JSON parsing
  logic for commands, patches, network requests, and MCP calls, and the
  app-server protocol was effectively just passing through an opaque blob.
  
  Typing this at the protocol boundary makes the contract clearer.

• chore: clean up argument-comment lint and roll out all-target CI on macOS (#16054)

  ## Why
  
  `argument-comment-lint` was green in CI even though the repo still had
  many uncommented literal arguments. The main gap was target coverage:
  the repo wrapper did not force Cargo to inspect test-only call sites, so
  examples like the `latest_session_lookup_params(true, ...)` tests in
  `codex-rs/tui_app_server/src/lib.rs` never entered the blocking CI path.
  
  This change cleans up the existing backlog, makes the default repo lint
  path cover all Cargo targets, and starts rolling that stricter CI
  enforcement out on the platform where it is currently validated.
  
  ## What changed
  
  - mechanically fixed existing `argument-comment-lint` violations across
  the `codex-rs` workspace, including tests, examples, and benches
  - updated `tools/argument-comment-lint/run-prebuilt-linter.sh` and
  `tools/argument-comment-lint/run.sh` so non-`--fix` runs default to
  `--all-targets` unless the caller explicitly narrows the target set
  - fixed both wrappers so forwarded cargo arguments after `--` are
  preserved with a single separator
  - documented the new default behavior in
  `tools/argument-comment-lint/README.md`
  - updated `rust-ci` so the macOS lint lane keeps the plain wrapper
  invocation and therefore enforces `--all-targets`, while Linux and
  Windows temporarily pass `-- --lib --bins`
  
  That temporary CI split keeps the stricter all-targets check where it is
  already cleaned up, while leaving room to finish the remaining Linux-
  and Windows-specific target-gated cleanup before enabling
  `--all-targets` on those runners. The Linux and Windows failures on the
  intermediate revision were caused by the wrapper forwarding bug, not by
  additional lint findings in those lanes.
  
  ## Validation
  
  - `bash -n tools/argument-comment-lint/run.sh`
  - `bash -n tools/argument-comment-lint/run-prebuilt-linter.sh`
  - shell-level wrapper forwarding check for `-- --lib --bins`
  - shell-level wrapper forwarding check for `-- --tests`
  - `just argument-comment-lint`
  - `cargo test` in `tools/argument-comment-lint`
  - `cargo test -p codex-terminal-detection`
  
  ## Follow-up
  
  - Clean up remaining Linux-only target-gated callsites, then switch the
  Linux lint lane back to the plain wrapper invocation.
  - Clean up remaining Windows-only target-gated callsites, then switch
  the Windows lint lane back to the plain wrapper invocation.
