• chore(cli) deprecate --full-auto (#20133)

  ## Summary
  Starts the process of getting rid of `--full-auto`, with some
  concessions:
  1. Fully removes the command from the tui, since it just resolves to the
  default permissions there, and encourages users to use the one-time
  trust flow if they're not in a trusted repo.
  2. Marks the command as deprecated in `codex exec`, in case users are
  actively relying on this. We'll remove in an upcoming n+X release.
  3. Cleans up some of the `codex sandbox` cli logic, to keep supporting
  legacy sandbox policies for now.
  
  This isn't the cleanest setup, but I think it is worthwhile to warn
  users for one release before hard-removing it.
  
  ## Testing

• Add environment provider snapshot (#20058)

  ## Summary
  - Change `EnvironmentProvider` to return concrete `Environment`
  instances instead of `EnvironmentConfigurations`.
  - Make `DefaultEnvironmentProvider` provide the provider-visible `local`
  environment plus optional `remote` environment from
  `CODEX_EXEC_SERVER_URL`.
  - Keep `EnvironmentManager` as the concrete cache while exposing its own
  explicit local environment for `local_environment()` fallback paths.
  
  ## Validation
  - `just fmt`
  - `git diff --check`

• permissions: make SessionConfigured profile-only (#19774)

  ## Why
  
  `SessionConfiguredEvent` is the internal event that tells clients what
  permissions are active for a session. Emitting both `sandbox_policy` and
  `permission_profile` leaves two possible authorities and forces every
  consumer to decide which one to honor. At this point in the migration,
  the profile is expressive enough to represent managed, disabled, and
  external sandbox enforcement, so the internal event can be profile-only.
  
  The wire compatibility concern is older serialized events or rollout
  data that only contain `sandbox_policy`; those still need to
  deserialize.
  
  ## What Changed
  
  - Removes `sandbox_policy` from `SessionConfiguredEvent` and makes
  `permission_profile` required.
  - Adds custom deserialization so old payloads with only `sandbox_policy`
  are upgraded to a cwd-anchored `PermissionProfile`.
  - Updates core event emission and TUI session handling to sync
  permissions from the profile directly.
  - Updates app-server response construction to derive the legacy
  `sandbox` response field from the active thread snapshot instead of from
  `SessionConfiguredEvent`.
  - Updates yolo-mode display logic to treat both
  `PermissionProfile::Disabled` and managed unrestricted filesystem plus
  enabled network as full-access, while still preserving the distinction
  between no sandbox and external sandboxing.
  
  ## Verification

  - `cargo test -p codex-protocol serialize_event --lib`
  - `cargo test -p codex-exec session_configured --lib`

• [codex] Shard exec Bazel integration test (#19862)

  ## Summary
  
  - shard `//codex-rs/exec:exec-all-test` into 8 Bazel shards
  - keep the existing `no-sandbox` test tag unchanged
  
  ## Why
  
  The Windows Bazel lane has been timing out this aggregated integration
  test target at the default 300s test timeout. The target runs the
  combined `codex-rs/exec/tests/all.rs` integration binary; sharding lets
  Bazel split the Rust test cases across parallel test actions instead of
  running the whole integration suite as one long action.
  
  ## Validation
  
  Not run locally, per the Codex repo workflow for development-phase
  changes.

• refactor: make auth loading async (#19762)

  ## Summary
  
  Auth loading used to expose synchronous construction helpers in several
  places even though some auth sources now need async work. This PR makes
  the auth-loading surface async and updates the callers to await it.
  
  This is intentionally only plumbing. It does not change how
  AgentIdentity tokens are decoded, how task runtime ids are allocated, or
  how JWT signatures are verified.
  
  ## Stack
  
  1. **This PR:** [refactor: make auth loading
  async](https://github.com/openai/codex/pull/19762)
  2. [refactor: load AgentIdentity runtime
  eagerly](https://github.com/openai/codex/pull/19763)
  3. [feat: verify AgentIdentity JWTs with
  JWKS](https://github.com/openai/codex/pull/19764)
  
  ## Important call sites
  
  | Area | Change |
  | --- | --- |
  | `codex-login` auth loading | `CodexAuth` and `AuthManager`
  construction paths now await auth loading. |
  | app-server startup | Auth manager construction is awaited during
  initialization. |
  | CLI/TUI/exec/MCP/chatgpt callers | Existing auth-loading calls now
  await the same behavior. |
  | cloud requirements storage loader | The loader becomes async so it can
  share the same auth construction path. |
  | auth tests | Tests that load auth now run in async contexts. |
  
  ## Testing
  
  Tests: targeted Rust auth test compilation, formatter, scoped Clippy
  fix, and Bazel lock check.

• permissions: migrate approval and sandbox consumers to profiles (#19393)

  ## Why
  
  Runtime decisions should not infer permissions from the lossy legacy
  sandbox projection once `PermissionProfile` is available. In particular,
  `Disabled` and `External` need to remain distinct, and managed profiles
  with split filesystem or deny-read rules should not be collapsed before
  approval, network, safety, or analytics code makes decisions.
  
  ## What Changed
  
  - Changes managed network proxy setup and network approval logic to use
  `PermissionProfile` when deciding whether a managed sandbox is active.
  - Migrates patch safety, Guardian/user-shell approval paths, Landlock
  helper setup, analytics sandbox classification, and selected
  turn/session code to profile-backed permissions.
  - Validates command-level profile overrides against the constrained
  `PermissionProfile` rather than a strict `SandboxPolicy` round trip.
  - Preserves configured deny-read restrictions when command profiles are
  narrowed.
  - Adds coverage for profile-backed trust, network proxy/approval
  behavior, patch safety, analytics classification, and command-profile
  narrowing.
  
  ## Verification
  
  - `cargo test -p codex-core direct_write_roots`
  - `cargo test -p codex-core runtime_roots_to_legacy_projection`
  - `cargo test -p codex-app-server
  requested_permissions_trust_project_uses_permission_profile_intent`

• [codex] Move config loading into codex-config (#19487)

  ## Why
  
  Config loading had become split across crates: `codex-config` owned the
  config types and merge logic, while `codex-core` still owned the loader
  that assembled the layer stack. This change consolidates that
  responsibility in `codex-config`, so the crate that defines config
  behavior also owns how configs are discovered and loaded.
  
  To make that move possible without reintroducing the old dependency
  cycle, the shell-environment policy types and helpers that
  `codex-exec-server` needs now live in `codex-protocol` instead of
  flowing through `codex-config`.
  
  This also makes the migrated loader tests more deterministic on machines
  that already have managed or system Codex config installed by letting
  tests override the system config and requirements paths instead of
  reading the host's `/etc/codex`.
  
  ## What Changed
  
  - moved the config loader implementation from `codex-core` into
  `codex-config::loader` and deleted the old `core::config_loader` module
  instead of leaving a compatibility shim
  - moved shell-environment policy types and helpers into
  `codex-protocol`, then updated `codex-exec-server` and other downstream
  crates to import them from their new home
  - updated downstream callers to use loader/config APIs from
  `codex-config`
  - added test-only loader overrides for system config and requirements
  paths so loader-focused tests do not depend on host-managed config state
  - cleaned up now-unused dependency entries and platform-specific cfgs
  that were surfaced by post-push CI
  
  ## Testing
  
  - `cargo test -p codex-config`
  - `cargo test -p codex-core config_loader_tests::`
  - `cargo test -p codex-protocol -p codex-exec-server -p
  codex-cloud-requirements -p codex-rmcp-client --lib`
  - `cargo test --lib -p codex-app-server-client -p codex-exec`
  - `cargo test --no-run --lib -p codex-app-server`
  - `cargo test -p codex-linux-sandbox --lib`
  - `cargo shear`
  - `just bazel-lock-check`
  
  ## Notes
  
  - I did not chase unrelated full-suite failures outside the migrated
  loader surface.
  - `cargo test -p codex-core --lib` still hits unrelated proxy-sensitive
  failures on this machine, and Windows CI still shows unrelated
  long-running/timeouting test noise outside the loader migration itself.

• permissions: make runtime config profile-backed (#19606)

  ## Why
  
  This supersedes #19391. During stack repair, GitHub marked #19391 as
  merged into a temporary stack branch rather than into `main`, so the
  runtime-config change needed a fresh PR.
  
  `PermissionProfile` is now the canonical permissions shape after #19231
  because it can distinguish `Managed`, `Disabled`, and `External`
  enforcement while also carrying filesystem rules that legacy
  `SandboxPolicy` cannot represent cleanly. Core config and session state
  still needed to accept profile-backed permissions without forcing every
  profile through the strict legacy bridge, which rejected valid runtime
  profiles such as direct write roots.
  
  The unrelated CI/test hardening that previously rode along with this PR
  has been split into #19683 so this PR stays focused on the permissions
  model migration.
  
  ## What Changed
  
  - Adds `Permissions.permission_profile` and
  `SessionConfiguration.permission_profile` as constrained runtime state,
  while keeping `sandbox_policy` as a legacy compatibility projection.
  - Introduces profile setters that keep `PermissionProfile`, split
  filesystem/network policies, and legacy `SandboxPolicy` projections
  synchronized.
  - Uses a compatibility projection for requirement checks and legacy
  consumers instead of rejecting profiles that cannot round-trip through
  `SandboxPolicy` exactly.
  - Updates config loading, config overrides, session updates, turn
  context plumbing, prompt permission text, sandbox tags, and exec request
  construction to carry profile-backed runtime permissions.
  - Preserves configured deny-read entries and `glob_scan_max_depth` when
  command/session profiles are narrowed.
  - Adds `PermissionProfile::read_only()` and
  `PermissionProfile::workspace_write()` presets that match legacy
  defaults.
  
  ## Verification
  
  - `cargo test -p codex-core direct_write_roots`
  - `cargo test -p codex-core runtime_roots_to_legacy_projection`
  - `cargo test -p codex-app-server
  requested_permissions_trust_project_uses_permission_profile_intent`

• permissions: remove legacy read-only access modes (#19449)

  ## Why
  
  `ReadOnlyAccess` was a transitional legacy shape on `SandboxPolicy`:
  `FullAccess` meant the historical read-only/workspace-write modes could
  read the full filesystem, while `Restricted` tried to carry partial
  readable roots. The partial-read model now belongs in
  `FileSystemSandboxPolicy` and `PermissionProfile`, so keeping it on
  `SandboxPolicy` makes every legacy projection reintroduce lossy
  read-root bookkeeping and creates unnecessary noise in the rest of the
  permissions migration.
  
  This PR makes the legacy policy model narrower and explicit:
  `SandboxPolicy::ReadOnly` and `SandboxPolicy::WorkspaceWrite` represent
  the old full-read sandbox modes only. Split readable roots, deny-read
  globs, and platform-default/minimal read behavior stay in the runtime
  permissions model.
  
  ## What changed
  
  - Removes `ReadOnlyAccess` from
  `codex_protocol::protocol::SandboxPolicy`, including the generated
  `access` and `readOnlyAccess` API fields.
  - Updates legacy policy/profile conversions so restricted filesystem
  reads are represented only by `FileSystemSandboxPolicy` /
  `PermissionProfile` entries.
  - Keeps app-server v2 compatible with legacy `fullAccess` read-access
  payloads by accepting and ignoring that no-op shape, while rejecting
  legacy `restricted` read-access payloads instead of silently widening
  them to full-read legacy policies.
  - Carries Windows sandbox platform-default read behavior with an
  explicit override flag instead of depending on
  `ReadOnlyAccess::Restricted`.
  - Refreshes generated app-server schema/types and updates tests/docs for
  the simplified legacy policy shape.
  
  ## Verification
  
  - `cargo check -p codex-app-server-protocol --tests`
  - `cargo check -p codex-windows-sandbox --tests`
  - `cargo test -p codex-app-server-protocol sandbox_policy_`

• permissions: make legacy profile conversion cwd-free (#19414)

  ## Why
  
  The profile conversion path still required a `cwd` even when it was only
  translating a legacy `SandboxPolicy` into a `PermissionProfile`. That
  made profile producers invent an ambient `cwd`, which is exactly the
  anchoring we are trying to remove from permission-profile data. A legacy
  workspace-write policy can be represented symbolically instead: `:cwd =
  write` plus read-only `:project_roots` metadata subpaths.
  
  This PR creates that cwd-free base so the rest of the stack can stop
  threading cwd through profile construction. Callers that actually need a
  concrete runtime filesystem policy for a specific cwd still have an
  explicitly named cwd-bound conversion.
  
  ## What Changed
  
  - `PermissionProfile::from_legacy_sandbox_policy` now takes only
  `&SandboxPolicy`.
  - `FileSystemSandboxPolicy::from_legacy_sandbox_policy` is now the
  symbolic, cwd-free projection for profiles.
  - The old concrete projection is retained as
  `FileSystemSandboxPolicy::from_legacy_sandbox_policy_for_cwd` for
  runtime/boundary code that must materialize legacy cwd behavior.
  - Workspace-write profiles preserve `CurrentWorkingDirectory` and
  `ProjectRoots` special entries instead of materializing cwd into
  absolute paths.
  
  ## Verification
  
  - `cargo check -p codex-protocol -p codex-core -p
  codex-app-server-protocol -p codex-app-server -p codex-exec -p
  codex-exec-server -p codex-tui -p codex-sandboxing -p

• Surface reasoning tokens in exec JSON usage (#19308)

  ## Summary
  
  Fixes #19022.
  
  `codex exec --json` currently emits `turn.completed.usage` with input,
  cached input, and output token counts, but drops the reasoning-token
  split that Codex already receives through thread token usage updates.
  Programmatic consumers that rely on the JSON stream, especially
  ephemeral runs that do not write rollout files, need this field to
  accurately display reasoning-model usage.
  
  This PR adds `reasoning_output_tokens` to the public exec JSON `Usage`
  payload and maps it from the existing `ThreadTokenUsageUpdated` total
  token usage data.
  
  ## Verification
  
  - Added coverage to
  `event_processor_with_json_output::token_usage_update_is_emitted_on_turn_completion`
  so `turn.completed.usage.reasoning_output_tokens` is asserted.
  - Updated SDK expectations for `run()` and `runStreamed()` so TypeScript
  consumers see the new usage field.
  - Ran `cargo test -p codex-exec`.
  - Ran `pnpm --filter ./sdk/typescript run build`.
  - Ran `pnpm --filter ./sdk/typescript run lint`.
  - Ran `pnpm --filter ./sdk/typescript exec jest --runInBand
  --testTimeout=30000`.

• 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

• Rename approvals reviewer variant to auto-review (#19056)

  ## Why
  
  `approvals_reviewer` now uses `auto_review` as the canonical config/API
  value after #18504, but the Rust enum variant and nearby helper/test
  names still used `GuardianSubagent` / guardian approval wording. That
  made follow-up code and reviews confusing even though the external value
  had already moved to Auto-review.
  
  ## What changed
  
  - Renamed `ApprovalsReviewer::GuardianSubagent` to
  `ApprovalsReviewer::AutoReview`.
  - Updated protocol, app-server, config, core, TUI, exec, and analytics
  test callsites.
  - Renamed nearby helper/test names from guardian approval wording to
  Auto-review wording where they refer to the approvals reviewer mode.
  - Preserved wire compatibility:
    - `auto_review` remains the canonical serialized value.
    - `guardian_subagent` remains accepted as a legacy alias.
  
  This intentionally does not rename the `[features].guardian_approval`
  key, `Feature::GuardianApproval`, `core/src/guardian`, analytics event
  names, or app-server Guardian review event types.
  
  ## Verification
  
  - `cargo test -p codex-protocol

• clients: send permission profiles to app-server (#18280)

  ## Why
  
  After app-server can accept `PermissionProfile`, first-party clients
  should stop preferring legacy sandbox fields when canonical permission
  information is available. This keeps the migration moving without
  removing legacy compatibility yet.
  
  The client side still has mixed surfaces during the stack: embedded
  thread start/resume/fork and exec initial turns can derive a profile
  directly from local config, while TUI remote sessions and some
  turn-start paths only have a legacy/server-context-safe sandbox
  projection. Those paths keep sending legacy sandbox fields rather than
  synthesizing or sending lossy/local-only profiles.
  
  ## What changed
  
  - Sends `permissionProfile` from exec and embedded TUI thread
  start/resume/fork requests when config has a representable profile.
  - Keeps legacy sandbox fallback for external sandbox policies, TUI
  remote thread lifecycle requests, and TUI turn-start requests that do
  not yet carry the active profile.
  - Sends the actual config-derived `permissionProfile` for exec initial
  turns instead of rebuilding one from the legacy sandbox projection.
  - Stores response `permissionProfile` as optional in TUI session state
  so external sandbox responses and compatibility payloads preserve
  `null`.
  - Updates tests for request construction and response mapping.
  
  ## Verification
  
  - `cargo check --tests -p codex-tui -p codex-exec`
  - `cargo test -p codex-tui app_server_session -- --nocapture`
  - `cargo test -p codex-exec thread_start_params -- --nocapture`
  - `cargo test -p codex-tui

• 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`

• Support multiple cwd filters for thread list (#18502)

  ## Summary
  
  - Teach app-server `thread/list` to accept either a single `cwd` or an
  array of cwd filters, returning threads whose recorded session cwd
  matches any requested path
  - Add `useStateDbOnly` as an explicit opt-in fast path for callers that
  want to answer `thread/list` from SQLite without scanning JSONL rollout
  files
  - Preserve backwards compatibility: by default, `thread/list` still
  scans JSONL rollouts and repairs SQLite state
  - Wire the new cwd array and SQLite-only options through app-server,
  local/remote thread-store, rollout listing, generated TypeScript/schema
  fixtures, proto output, and docs
  
  ## Test Plan
  
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-rollout`
  - `cargo test -p codex-thread-store`
  - `cargo test -p codex-app-server thread_list`
  - `just fmt`
  - `just fix -p codex-app-server-protocol -p codex-rollout -p
  codex-thread-store -p codex-app-server`
  - `cargo build -p codex-cli --bin codex`

• app-server: expose thread permission profiles (#18278)

  ## Why
  
  The `PermissionProfile` migration needs app-server clients to see the
  same constrained permission model that core is using at runtime. Before
  this PR, thread lifecycle responses only exposed the legacy
  `SandboxPolicy` shape, so clients still had to infer active permissions
  from sandbox fields. That makes downstream resume, fork, and override
  flows harder to make `PermissionProfile`-first.
  
  External sandbox policies are intentionally excluded from this canonical
  view. External enforcement cannot be round-tripped as a
  `PermissionProfile`, and exposing a lossy root-write profile would let
  clients accidentally change sandbox semantics if they echo the profile
  back later.
  
  ## What changed
  
  - Adds the app-server v2 `PermissionProfile` wire shape, including
  filesystem permissions and glob scan depth metadata.
  - Adds `PermissionProfileNetworkPermissions` so the profile response
  does not expose active network state through the older
  additional-permissions naming.
  - Returns `permissionProfile` from thread start, resume, and fork
  responses when the active sandbox can be represented as a
  `PermissionProfile`.
  - Keeps legacy `sandbox` in those responses for compatibility and
  documents `permissionProfile` as canonical when present.
  - Makes lifecycle `permissionProfile` nullable and returns `null` for
  `ExternalSandbox` to avoid exposing a lossy profile.
  - Regenerates the app-server JSON schema and TypeScript fixtures.
  
  ## Verification
  
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-app-server
  thread_response_permission_profile_omits_external_sandbox --
  --nocapture`

• Fix exec inheritance of root shared flags (#18630)

  Addresses #18113
  
  Problem: Shared flags provided before the exec subcommand were parsed by
  the root CLI but not inherited by the exec CLI, so exec sessions could
  run with stale or default sandbox and model configuration.
  
  Solution: Move shared TUI and exec flags into a common option block and
  merge root selections into exec before dispatch, while preserving exec's
  global subcommand flag behavior.

• Add sorting/backwardsCursor to thread/list and new thread/turns/list api (#17305)

  To improve performance of UI loads from the app, add two main
  improvements:
  1. The `thread/list` api now gets a `sortDirection` request field and a
  `backwardsCursor` to the response, which lets you paginate forwards and
  backwards from a window. This lets you fetch the first few items to
  display immediately while you paginate to fill in history, then can
  paginate "backwards" on future loads to catch up with any changes since
  the last UI load without a full reload of the entire data set.
  2. Added a new `thread/turns/list` api which also has sortDirection and
  backwardsCursor for the same behavior as `thread/list`, allowing you the
  same small-fetch for immediate display followed by background fill-in
  and resync catchup.

• sandbox: remove dead seatbelt helper and update tests (#17859)

  ## Why
  
  `spawn_command_under_seatbelt()` in `codex-rs/core/src/seatbelt.rs` had
  fallen out of production use and was only referenced by test-only
  wrappers. That left us with sandbox tests that could stay green even if
  the actual seatbelt exec path regressed, because production shell
  execution now flows through `SandboxManager::transform()` and
  `ExecRequest::from_sandbox_exec_request()` instead of that helper.
  
  Removing the dead helper also exposed one downstream `codex-exec`
  integration test that still imported it, which broke `just clippy`.
  
  ## What Changed
  
  - Removed `codex-rs/core/src/seatbelt.rs` and stopped exporting
  `codex_core::seatbelt`.
  - Removed the redundant `codex-rs/core/tests/suite/seatbelt.rs` coverage
  that only exercised the dead helper.
  - Kept the `openpty` regression check, but moved it into
  `codex-rs/core/tests/suite/exec.rs` so it now runs through
  `process_exec_tool_call()`.
  - Fixed the seatbelt denial test in `codex-rs/core/tests/suite/exec.rs`
  to use `/usr/bin/touch`, so it actually exercises the sandbox instead of
  a nonexistent path.
  - Updated `codex-rs/exec/tests/suite/sandbox.rs` on macOS to build the
  sandboxed command through `build_exec_request()` and spawn the
  transformed command, instead of importing the removed helper.
  - Left the lower-level seatbelt policy coverage in
  `codex-rs/sandboxing/src/seatbelt_tests.rs`, where the policy generator
  is still covered directly.
  
  ## Verification
  
  - `cargo test -p codex-core suite::exec::`
  - `cargo test -p codex-exec`
  - `cargo clippy -p codex-exec --tests -- -D warnings`

• Expose instruction sources (AGENTS.md) via app server (#17506)

  Addresses #17498
  
  Problem: The TUI derived /status instruction source paths from the local
  client environment, which could show stale <none> output or incorrect
  paths when connected to a remote app server.
  
  Solution: Add an app-server v2 instructionSources snapshot to thread
  start/resume/fork responses, default it to an empty list when older
  servers omit it, and render TUI /status from that server-provided
  session data.
  
  Additional context: The app-server field is intentionally named
  instructionSources rather than AGENTS.md-specific terminology because
  the loaded instruction sources can include global instructions, project
  AGENTS.md files, AGENTS.override.md, user-defined instruction files, and
  future dynamic sources.

• Fix thread/list cwd filtering for Windows verbatim paths (#17414)

  Addresses #17302
  
  Problem: `thread/list` compared cwd filters with raw path equality, so
  `resume --last` could miss Windows sessions when the saved cwd used a
  verbatim path form and the current cwd did not.
  
  Solution: Normalize cwd comparisons through the existing path comparison
  utilities before falling back to direct equality, and add Windows
  regression coverage for verbatim paths. I made this a general utility
  function and replaced all of the duplicated instance of it across the
  code base.

• 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.

• 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
  -- --nocapture`
  - `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.

• Validate exec input before starting app-server (#16890)

  Addresses #16443
  
  This was a regression introduced when we moved exec on top of the app
  server APIs.
  
  Problem: codex exec resolved prompt/stdin and output schema after
  starting the in-process app-server, so early `process::exit(1)` paths
  could bypass session shutdown.
  
  Solution: Resolve prompt/stdin and output schema before app-server
  startup so validation failures happen before any exec session is
  created.

  Solution: Gate the bwrap warning on the active sandbox policy and skip
  it for danger-full-access and external-sandbox modes.

• remove temporary ownership re-exports (#16626)

  Stacked on #16508.
  
  This removes the temporary `codex-core` / `codex-login` re-export shims
  from the ownership split and rewrites callsites to import directly from
  `codex-model-provider-info`, `codex-models-manager`, `codex-api`,
  `codex-protocol`, `codex-feedback`, and `codex-response-debug-context`.
  
  No behavior change intended; this is the mechanical import cleanup layer
  split out from the ownership move.

• Fix fork source display in /status (expose forked_from_id in app server) (#16596)

  Addresses #16560
  
  Problem: `/status` stopped showing the source thread id in forked TUI
  sessions after the app-server migration.
  
  Solution: Carry fork source ids through app-server v2 thread data and
  the TUI session adapter, and update TUI fixtures so `/status` matches
  the old TUI behavior.

• chore: move codex-exec unit tests into sibling files (#16581)

  ## Why
  
  `codex-rs/exec/src/lib.rs` already keeps unit tests in a sibling
  `lib_tests.rs` module so the implementation stays top-heavy and easier
  to read. This applies that same layout to the rest of
  `codex-rs/exec/src` so each production file keeps its entry points and
  helpers ahead of test code.
  
  ## What
  
  - Move inline unit tests out of `cli.rs`, `main.rs`,
  `event_processor_with_human_output.rs`, and
  `event_processor_with_jsonl_output.rs` into sibling `*_tests.rs` files.
  - Keep test modules wired through `#[cfg(test)]` plus `#[path = "..."]
  mod tests;`, matching the `lib.rs` pattern.
  - Preserve the existing test coverage and assertions while making this a
  source-layout-only refactor.
  
  ## Verification
  
  - `cargo test -p codex-exec`
