• feat: split memories part 2 (#19860)

  Keep extracting memories out of core and moving the write trigger in the
  app-server
  This is temporary and it should move at the client level as a follow-up
  This makes core fully independant from `codex-memories-write`

• Add MultiAgentV2 root and subagent context hints (#19805)

  ## Why
  
  MultiAgentV2 sessions need startup guidance that matches the role of the
  thread that is actually being created. Root agents and subagents have
  different responsibilities, and forked subagents can inherit parent
  rollout history. If the parent hint is carried into the child context,
  the child can see stale or conflicting developer guidance before its own
  session-specific context is added.
  
  ## What changed
  
  - Added `features.multi_agent_v2.root_agent_usage_hint_text` and
  `features.multi_agent_v2.subagent_usage_hint_text` config fields,
  including schema/config parsing support.
  - Injected the matching root or subagent hint into the initial context
  as its own developer message when `multi_agent_v2` is enabled.
  - Filtered configured MultiAgentV2 usage-hint developer messages out of
  forked parent history so a child thread receives fresh guidance for its
  own session source/config.
  - Added targeted coverage for config parsing, initial-context rendering,
  feature-config deserialization, and forked-history filtering.
  
  ## Context examples
  
  With this config:
  
  ```toml
  [features.multi_agent_v2]
  enabled = true
  root_agent_usage_hint_text = "Root guidance."
  subagent_usage_hint_text = "Subagent guidance."
  ```
  
  A root thread initial context renders the root hint as a standalone
  developer message:
  
  ```text
  [developer]
  <existing developer context, when present>
  
  [developer]
  Root guidance.
  ```
  
  A subagent thread initial context renders the subagent hint instead:
  
  ```text
  [developer]
  <existing developer context, when present>
  
  [developer]
  Subagent guidance.
  ```
  
  When a subagent forks parent history, any parent developer message whose
  text exactly matches the configured MultiAgentV2 root or subagent hint
  is omitted from the forked history before the child receives its fresh
  subagent hint.

• Add remote plugin uninstall API (#19456)

  ## Summary
  - Adds the remote `plugin/uninstall` request form using required
  `pluginId` plus optional `remoteMarketplaceName`, while preserving local
  `pluginId` uninstall.
  - Adds `codex_core_plugins::remote::uninstall_remote_plugin` for the
  deployed ChatGPT plugin backend uninstall path and validates the backend
  returns the same id with `enabled: false`.
  - Routes app-server remote uninstall through feature checks, remote
  plugin id validation, backend mutation, local downloaded cache deletion,
  cache clearing, docs, and regenerated protocol schemas.
  
  ## Tests
  - `just write-app-server-schema`
  - `just fmt`
  - `cargo test -p codex-app-server-protocol

• Add codex update command (#19933)

  ## Why
  
  Addresses #9274
  
  Running `codex update` currently starts an interactive Codex session
  with `update` as the prompt. That is a rough edge for users who expect a
  direct self-update command after seeing the existing update notice, and
  it forces them to copy the suggested package-manager command manually.
  
  ## What changed
  
  - Added a top-level `codex update` subcommand.
  - Reused the existing install-channel detection and update command
  runner that the TUI already uses for update prompts.
  - Exposed the update-action lookup from `codex-tui` so the CLI can
  invoke the same behavior.
  - Added CLI coverage to ensure `codex update` is parsed as a subcommand
  instead of becoming an interactive prompt.
  
  ## Verification
  
  - `cargo test -p codex-cli`
  - `cargo test -p codex-tui update_action::tests`

• app-server-protocol: mark permission profiles experimental (#19899)

  ## Why
  
  `PermissionProfile` is now the canonical internal permissions
  representation, but the app-server wire shape is still intentionally
  unstable while the migration continues. Stable app-server clients should
  not see or generate code for these fields until the wire format settles.
  
  ## What changed
  
  - Marks every app-server v2 field that sends `PermissionProfile` as
  experimental, including `command/exec`, `thread/start`, `thread/resume`,
  `thread/fork`, and `turn/start` request/response payloads.
  - Enables per-field experimental inspection for `command/exec`, so
  `permissionProfile` is gated without making the entire method
  experimental.
  - Fixes the generated TypeScript schema filter to be comment-aware. The
  previous scanner treated apostrophes inside doc comments as string
  delimiters, so some experimental fields leaked into stable TypeScript
  even though stable JSON was filtered correctly.
  
  ## Verification
  
  - `cargo test -p codex-app-server-protocol`

• permissions: store thread sessions as profiles (#19776)

  ## Why
  
  After thread sessions have a required `PermissionProfile`, the TUI no
  longer needs to cache a separate legacy `SandboxPolicy` in
  `ThreadSessionState`. Keeping the legacy field would reintroduce two
  permission authorities in the session cache and make later
  replay/switching logic easier to get wrong.
  
  This PR keeps legacy app-server compatibility at the ingestion boundary:
  old `sandbox` response values are still accepted, but they are
  immediately converted to a cwd-anchored profile.
  
  ## What Changed
  
  - Removes `ThreadSessionState.sandbox_policy`.
  - Updates active-session permission syncing to write only the current
  `PermissionProfile`.
  - Updates thread-read/replay/test fixtures to use profiles as the cached
  session permission source.
  - Leaves legacy `sandbox` fields in app-server request/response protocol
  paths unchanged; those are compatibility boundaries and are converted
  before entering cached TUI state.
  
  ## Verification

  - `cargo test -p codex-tui

• Allow large remote app-server resume responses (#19920)

  ## Why
  
  Remote TUI resume uses the app-server websocket client. That client
  inherited tungstenite's default `16 MiB` frame limit, so a large saved
  session could make `thread/resume` return a single JSON-RPC response
  frame that the client rejected before the TUI could deserialize or
  render it.
  
  Fixes #19837
  
  ## What Changed
  
  - Configure the remote app-server websocket client with a bounded `128
  MiB` max frame/message size.
  - Preserve the concrete remote worker exit reason when completing
  pending requests after a transport/read failure instead of replacing it
  with a generic channel-closed error.
  - Add a regression test that sends a single `>16 MiB` JSON-RPC response
  frame and verifies the typed request succeeds.
  
  Note: This isn't a perfect fix. It really just moves the limit to a much
  larger value. I looked at a bunch of other potential fixes (both
  server-side and client-side), and they all involved significant
  complexity, had backward-compatibility impact, or impacted performance
  of common use cases. This simple fix should address the vast majority of
  remote use cases.
  
  ## Verification
  
  I reproed the problem locally using a long rollout. Verified that fix
  addresses connection drop.

• permissions: derive snapshot sandbox projections (#19775)

  ## Why
  
  `ThreadConfigSnapshot` is used by app-server and thread metadata code as
  a stable view of active runtime settings. Keeping both `sandbox_policy`
  and `permission_profile` in the snapshot duplicates permission state and
  makes it possible for the legacy projection to drift from the canonical
  profile.
  
  The legacy `sandbox` value is still needed at app-server compatibility
  boundaries, so this PR derives it on demand from the snapshot profile
  and cwd instead of storing it.
  
  ## What Changed
  
  - Removes `ThreadConfigSnapshot.sandbox_policy`.
  - Adds `ThreadConfigSnapshot::sandbox_policy()` as a compatibility
  projection from `permission_profile` plus `cwd`.
  - Updates app-server response/metadata code and tests to call the
  projection only where legacy fields still exist.
  - Keeps snapshot construction profile-only so split filesystem rules,
  disabled enforcement, and external enforcement remain represented by the
  canonical profile.
  
  ## Verification
  
  - `cargo test -p codex-app-server
  thread_response_permission_profile_preserves_enforcement --lib`
  - `cargo test -p codex-core

• 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.

• Avoid persisting ShutdownComplete after thread shutdown (#19630)

  ## Why
  
  Fixes #19475.
  
  `codex exec` can finish successfully and then emit an `ERROR` on stderr:
  
  ```text
  failed to record rollout items: thread <id> not found
  ```
  
  That happens because shutdown closes the live thread writer before
  emitting `ShutdownComplete`. The terminal event was still using the
  normal `send_event_raw` path, so it tried to append rollout items
  through a recorder that had already been removed. The answer is correct,
  but wrappers that treat stderr as failure can retry completed exec runs.
  
  This looks like a likely recent regression from
  [#18882](https://github.com/openai/codex/pull/18882), which routed live
  thread writes through `ThreadStore` and added the shutdown-time live
  writer close. I have not bisected this, so the PR treats #18882 as the
  likely source based on the affected shutdown code path rather than a
  proven first-bad commit.
  
  ## What Changed
  
  `ShutdownComplete` now bypasses rollout persistence after thread
  shutdown and is delivered directly to clients. The shutdown path still
  records the protocol event in the rollout trace before delivery,
  preserving trace visibility without attempting a post-shutdown
  thread-store append.
  
  The change also adds a regression test with the in-memory thread store
  to assert that shutdown creates and shuts down the live thread without
  appending another item after shutdown.

• refactor: load agent identity runtime eagerly (#19763)

  ## Summary
  
  AgentIdentity auth previously registered the process task lazily behind
  a `OnceCell`. That meant the auth object could be constructed before its
  runtime task binding was known.
  
  This PR makes AgentIdentity auth load the runtime task at auth load time
  and stores the resulting process task id directly on the auth object.
  The model-provider call path can then read a concrete task id instead of
  handling a missing lazy value.
  
  ## Stack
  
  1. [refactor: make auth loading
  async](https://github.com/openai/codex/pull/19762) (merged)
  2. **This PR:** [refactor: load AgentIdentity runtime
  eagerly](https://github.com/openai/codex/pull/19763)
  3. [fix: configure AgentIdentity AuthAPI base
  URL](https://github.com/openai/codex/pull/19904)
  4. [feat: verify AgentIdentity JWTs with
  JWKS](https://github.com/openai/codex/pull/19764)
  
  ## Important call sites
  
  | Area | Change |
  | --- | --- |
  | `AgentIdentityAuth::load` | Registers the process task during auth
  loading and stores `process_task_id`. |
  | `CodexAuth::from_agent_identity_jwt` | Awaits AgentIdentity auth
  loading. |
  | model-provider auth | Reads a concrete `process_task_id` instead of an
  optional lazy value. |
  | AgentIdentity auth tests | Mock task registration now covers eager
  runtime allocation. |
  
  ## Design decisions
  
  AgentIdentity auth now treats task registration as part of constructing
  a usable auth object. That matches how callers use the value: once auth
  is present, the model-provider path expects the task-scoped assertion
  data to be ready.
  
  ## Testing
  
  Tests: targeted Rust auth test compilation, formatter, scoped Clippy
  fix, and Bazel lock check.

• permissions: require profiles in TUI thread state (#19773)

  ## Why
  
  `ThreadSessionState` is the TUI's cached view of an app-server session.
  To make `PermissionProfile` the canonical runtime permissions model,
  cached thread sessions need to always have a profile instead of treating
  the profile as an optional supplement to a legacy `sandbox` response
  field.
  
  The main compatibility concern is older app-server v2 lifecycle
  responses that only include `sandbox` and omit `permissionProfile`:
  
  - `thread/start` -> `ThreadStartResponse.sandbox`
  - `thread/resume` -> `ThreadResumeResponse.sandbox`
  - `thread/fork` -> `ThreadForkResponse.sandbox`
  
  Those responses must still hydrate correctly when the TUI is pointed at
  an older app-server. This PR converts the legacy `sandbox` value into a
  `PermissionProfile` immediately at response ingestion time, using the
  response `cwd`, so cached sessions do not carry an optional profile that
  can later reinterpret cwd-bound grants against a different thread cwd.
  
  This fallback is intentionally boundary compatibility. The follow-up PRs
  in this stack continue the cleanup by making `SessionConfiguredEvent`
  profile-only, deriving sandbox projections from snapshots only when an
  API still needs them, and then removing `sandbox_policy` from
  `ThreadSessionState`.
  
  ## What Changed
  
  - Makes `ThreadSessionState.permission_profile` required.
  - Converts legacy app-server response `sandbox` values into a
  `PermissionProfile` at ingestion time using the response cwd.
  - Ensures `thread/read` hydration does not reuse a primary session
  profile that may be anchored to a different cwd; it uses the active
  widget permission settings for the read thread fallback instead of
  reusing cached primary-session permissions.
  - Keeps the app-server request path unchanged: embedded sessions send
  profiles, while remote sessions continue using legacy sandbox overrides
  for compatibility.

• Stabilize plugin MCP fixture tests (#19452)

  ## Why
  
  Recent `main` CI had repeated flakes in the plugin fixture tests:
  
  - `codex-core::all
  suite::plugins::explicit_plugin_mentions_inject_plugin_guidance` failed
  in runs
  [24909500958](https://github.com/openai/codex/actions/runs/24909500958),
  [24908076251](https://github.com/openai/codex/actions/runs/24908076251),
  [24906197645](https://github.com/openai/codex/actions/runs/24906197645),
  and
  [24898949647](https://github.com/openai/codex/actions/runs/24898949647).
  - `codex-core::all suite::plugins::plugin_mcp_tools_are_listed` failed
  in runs
  [24909500958](https://github.com/openai/codex/actions/runs/24909500958),
  [24908076251](https://github.com/openai/codex/actions/runs/24908076251),
  and
  [24898949647](https://github.com/openai/codex/actions/runs/24898949647).
  
  The failures were in the same plugin/MCP fixture family: assertions
  expected sample plugin guidance or tool inventory, but the test could
  observe the session before the sample MCP server had finished startup.
  
  ## Root Cause
  
  `explicit_plugin_mentions_inject_plugin_guidance` submitted the user
  turn immediately after constructing the session. MCP startup is
  asynchronous, so on a slower or busier CI runner the prompt could be
  built before the sample plugin MCP server had reported its tools. That
  made the test depend on scheduler timing rather than the fixture being
  ready.
  
  `plugin_mcp_tools_are_listed` already needed the same readiness
  condition, but its wait logic was local to that test.
  
  ## What Changed
  
  - Added a shared `wait_for_sample_mcp_ready` helper for the plugin
  fixture tests.
  - Wait for `McpStartupComplete` before submitting the explicit plugin
  mention turn.
  - Reuse the same readiness helper in the MCP tool-listing test.
  
  ## Why This Should Be Reliable
  
  The tests now wait for the explicit readiness signal from the sample MCP
  server before asserting guidance or tools derived from that server. This
  removes the startup race while still exercising the real fixture path,
  so the assertions should only run after the plugin inventory is
  deterministic.
  
  ## Verification
  
  - `cargo test -p codex-core --test all plugins::`
  - GitHub CI for this PR is passing.

• disallow fileparams metadata for custom mcps (#19836)

  ## Summary
  Disallow fileParams metadata for custom MCPs 
  
  Restricts Codex openai/fileParams handling to the first-party codex_apps
  MCP server. Custom MCP servers may still advertise the metadata, but
  Codex now ignores it for upload rewriting, preventing non-Apps tools
  from receiving signed OpenAI file refs for local paths. Added a
  regression test for the allowed and denied cases.

• permissions: derive config defaults as profiles (#19772)

  ## Why
  
  This continues the permissions migration by making legacy config default
  resolution produce the canonical `PermissionProfile` first. The legacy
  `SandboxPolicy` projection should stay available at compatibility
  boundaries, but config loading should not create a legacy policy just to
  immediately convert it back into a profile.
  
  Specifically, when `default_permissions` is not specified in
  `config.toml`, instead of creating a `SandboxPolicy` in
  `codex-rs/core/src/config/mod.rs` and then trying to derive a
  `PermissionProfile` from it, we use `derive_permission_profile()` to
  create a more faithful `PermissionProfile` using the values of
  `ConfigToml` directly.
  
  This also keeps the existing behavior of `sandbox_workspace_write` and
  extra writable roots after #19841 replaced `:cwd` with `:project_roots`.
  Legacy workspace-write defaults are represented as symbolic
  `:project_roots` write access plus symbolic project-root metadata
  carveouts. Extra absolute writable roots are still added directly and
  continue to get concrete metadata protections for paths that exist under
  those roots.
  
  The platform sandboxes differ when a symbolic project-root subpath does
  not exist yet.
  
  * **Seatbelt** can encode literal/subpath exclusions directly, so macOS
  emits project-root metadata subpath policies even if `.git`, `.agents`,
  or `.codex` do not exist.
  * **bwrap** has to materialize bind-mount targets. Binding `/dev/null`
  to a missing `.git` can create a host-visible placeholder that changes
  Git repo discovery. Binding missing `.agents` would not affect Git
  discovery, but it would still create a host-visible project metadata
  placeholder from an automatic compatibility carveout. Linux therefore
  skips only missing automatic `.git` and `.agents` read-only metadata
  masks; missing `.codex` remains protected so first-time project config
  creation goes through the protected-path approval flow. User-authored
  `read` and `none` subpath rules keep normal bwrap behavior, and `none`
  can still mask the first missing component to prevent creation under
  writable roots.
  
  ## What Changed
  
  - Adds profile-native helpers for legacy workspace-write semantics,
  including `PermissionProfile::workspace_write_with()`,
  `FileSystemSandboxPolicy::workspace_write()`, and
  `FileSystemSandboxPolicy::with_additional_legacy_workspace_writable_roots()`.
  - Makes `FileSystemSandboxPolicy::workspace_write()` the single legacy
  workspace-write constructor so both `from_legacy_sandbox_policy()` and
  `From<&SandboxPolicy>` include the project-root metadata carveouts.
  - Removes the no-carveout `legacy_workspace_write_base_policy()` path
  and the `prune_read_entries_under_writable_roots()` cleanup that was
  only needed by that split construction.
  - Adds `ConfigToml::derive_permission_profile()` for legacy sandbox-mode
  fallback resolution; named `default_permissions` profiles continue
  through the permissions profile pipeline instead of being reconstructed
  from `sandbox_mode`.
  - Updates `Config::load()` to start from the derived profile, validate
  that it still has a legacy compatibility projection, and apply
  additional writable roots directly to managed workspace-write filesystem
  policies.
  - Updates Linux bwrap argument construction so missing automatic
  `.git`/`.agents` symbolic project-root read-only carveouts are skipped
  before emitting bind args; missing `.codex`, user-authored `read`/`none`
  subpath rules, and existing missing writable-root behavior are
  preserved.
  - Adds coverage that legacy workspace-write config produces symbolic
  project-root metadata carveouts, extra legacy workspace writable roots
  still protect existing metadata paths such as `.git`, and bwrap skips
  missing `.git`/`.agents` project-root carveouts while preserving missing
  `.codex` and user-authored missing subpath rules.

• Streamline review and feedback handlers (#19498)

  ## Why
  
  The remaining review, interrupt, fuzzy search, feedback, and git-diff
  handlers still had local send-error branches that obscured otherwise
  simple request handling. This final slice flattens those handlers
  without changing the public protocol behavior.
  
  ## What Changed
  
  - Streamlined review start, turn interrupt, fuzzy search session,
  feedback upload, and git diff handlers in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  - Converted validation and upload failures into returned JSON-RPC errors
  where that avoids nested `send_error`/`return` blocks.
  - Left unrelated sandbox setup and notification code untouched.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::review --

• Show action required in terminal title (#18372)

  Implements #18162
  
  This updates the TUI terminal title to show an explicit action-required
  state when Codex is blocked on user approval or input. The terminal
  title now uses the activity title item to cover both active work and
  blocked-on-user states, while still accepting the legacy spinner config
  value.
  
  Changes
  - Rename the terminal title item from `spinner` to `activity` while
  preserving legacy config compatibility
  - Show `[ ! ] Action Required `while approval or input overlays are
  active, with a blinking `[ . ]` alternate state
  - Suppress the normal working spinner while Codex is blocked on user
  action
  - Add targeted coverage for action-required title behavior and legacy
  title-item parsing
  
  Testing
  - Trigger an approval or input modal and confirm the tab title
  alternates between `[ ! ] Action Required` and `[ . ] Action Required`
  - Disable the activity title item and confirm the action-required title
  does not appear
  - Resolve the prompt and confirm the title returns to the normal
  spinning/idel state

• Streamline turn and realtime handlers (#19497)

  ## Why
  
  Turn and realtime handlers had nested validation and send-error branches
  that made the request path longer than the behavior warranted. This
  slice keeps the same request semantics while letting the handlers return
  errors from the failing step.
  
  ## What Changed
  
  - Streamlined turn start, injected item, and turn steer request handling
  in `codex-rs/app-server/src/codex_message_processor.rs`.
  - Applied the same result-returning shape to realtime session response
  handlers.
  - Preserved existing request validation and thread-manager interactions.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::turn_start --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::turn_steer --

• Streamline thread resume and fork handlers (#19495)

  ## Why
  
  Thread resume and fork had some of the deepest error-handling
  indentation in this area because helpers emitted request errors
  directly. Returning those failures gives the handlers a single request
  boundary while preserving the async pending-resume behavior.
  
  ## What Changed
  
  - Converted thread resume helpers in
  `codex-rs/app-server/src/codex_message_processor.rs` to return `Result`
  values for validation and view loading failures.
  - Applied the same pattern to thread fork request handling.
  - Simplified pending resume error construction by using the shared
  JSON-RPC error helpers.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::thread_resume --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::thread_fork --

• [codex] Trace cancelled inference streams (#19839)

  Records cancelled inference streams when Codex stops consuming a
  provider response before `response.completed`, preserving complete
  output items observed before cancellation.
  
  Also closes still-running inference calls when the owning turn ends, so
  reduced rollout traces do not leave stale `Running` inference nodes.
  
  Covered by focused reducer coverage and a core stream-drop test for
  partial output preservation.

• Streamline thread read handlers (#19494)

  ## Why
  
  The thread read/list handlers mostly assemble views, but their error
  handling was interleaved with response emission. Returning view-building
  errors from the helper path keeps those handlers focused on data
  assembly.
  
  ## What Changed
  
  - Added a small mapper for `ThreadReadViewError` to JSON-RPC errors in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  - Streamlined thread list, loaded-thread, read, turn-list, and summary
  handlers to produce result values for the request boundary.
  - Kept the existing invalid-request vs internal-error distinctions for
  missing or unreadable thread data.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all conversation_summary --

• Publish Python SDK with Codex-pinned versioning (#18996)

  **note**: a large chunk of this diff comes from regenerating Python
  types after app-server schema changes on `main`.
  
  This is PR 3 of 3 for the Python SDK PyPI publishing split. PR #18862
  refreshed the generated SDK surface, and PR #18865 made the runtime
  package publishable as `openai-codex-cli-bin`; this final PR makes the
  SDK package publishable as `openai-codex-app-server-sdk` and pins both
  packages to the same Codex runtime version.
  
  The key idea is that the published SDK version is the Codex runtime
  version. That one version now drives the SDK package version, the exact
  runtime dependency, the client version reported by the SDK, and the
  bootstrap runtime pin. This keeps release-time versioning in one lane
  instead of scattering checked-in literals through the package.
  
  ## What changed
  
  - Rename the SDK distribution from `codex-app-server-sdk` to
  `openai-codex-app-server-sdk` for conflict-free PyPI publishing.
  - Use `stage-sdk --codex-version ...` with one Codex version for both
  the SDK package version and exact `openai-codex-cli-bin` dependency.
  - Preserve hidden legacy `--runtime-version` / `--sdk-version` args only
  to reject mismatched versions during staging.
  - Map PEP 440 package versions back to Codex release tags for runtime
  setup downloads, e.g. `0.116.0a1` -> `rust-v0.116.0-alpha.1`.
  - Derive `codex_app_server.__version__`, the default
  `AppServerConfig.client_version`, and
  `_runtime_setup.pinned_runtime_version()` from the SDK package/project
  version instead of hardcoding duplicate version strings.
  - Carry the current generated SDK refresh from `main` so
  `generate-types` stays clean after recent app-server schema changes.
  - Update `sdk/python/uv.lock` for the renamed editable package.
  
  ## Validation
  
  - `uv run --extra dev pytest` in `sdk/python` -> 59 passed, 37 skipped.
  - Targeted `uv run ruff check` for the touched SDK files.
  - `git diff --check`.
  - Staged runtime with `--codex-version rust-v0.116.0-alpha.1
  --platform-tag macosx_11_0_arm64`.
  - Staged SDK with `--codex-version rust-v0.116.0-alpha.1`.
  - Built runtime wheel, SDK wheel, and SDK sdist.
  - `twine check /tmp/codex-python-pr3-build/dist/*` -> passed.
  - Clean venv smoke installed `openai-codex-app-server-sdk==0.116.0a1`
  from local dist and pulled `openai-codex-cli-bin==0.116.0a1`.
  - Smoke imports passed for `Codex` and `bundled_codex_path()`.

• [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.

• Streamline thread mutation handlers (#19493)

  ## Why
  
  Thread mutation handlers had many short error branches whose only job
  was to emit a JSON-RPC error and stop. This slice keeps those errors
  visible, but lets each handler build a result and return early from
  validation helpers instead of nesting the main path.
  
  ## What Changed
  
  - Streamlined thread archive/unarchive, rename, memory, metadata,
  rollback, compact, background terminal, shell, and guardian handlers in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  - Reused shared JSON-RPC error constructors in
  `codex-rs/app-server/src/bespoke_event_handling.rs` for rollback-related
  request failures.
  - Preserved direct `send_error` calls where they remain the simplest
  boundary for pending async event responses.

  - `cargo test -p codex-app-server --test all v2::thread_rollback --

• Streamline thread start handler (#19492)

  ## Why
  
  The thread start handler mixed request validation, thread construction,
  dynamic-tool validation, and JSON-RPC error emission in one nested flow.
  Returning request errors from the helper path makes the successful setup
  path easier to follow.
  
  ## What Changed
  
  - Reworked `thread/start` handling in
  `codex-rs/app-server/src/codex_message_processor.rs` so helper methods
  return `Result` and the handler emits one result.
  - Moved dynamic-tool validation failures into returned JSON-RPC errors
  instead of local `send_error` branches.
  - Preserved the existing thread creation and task-spawning behavior.

• permissions: remove cwd special path (#19841)

  ## Why
  
  The experimental `PermissionProfile` API had both `:cwd` and
  `:project_roots` special filesystem paths, which made the permission
  root ambiguous. This PR removes the unstable `current_working_directory`
  special path before the permissions API is stabilized, so callers use
  `:project_roots` for symbolic project-root access.
  
  ## What changed
  
  - Removes `FileSystemSpecialPath::CurrentWorkingDirectory` from protocol
  and app-server protocol models, plus regenerated app-server
  JSON/TypeScript schemas.
  - Replaces internal `:cwd` permission entries with `:project_roots`
  entries.
  - Keeps the existing cwd-update behavior for legacy-shaped
  workspace-write profiles, while removing the deleted
  `CurrentWorkingDirectory` case from that compatibility path.
  - Keeps `PermissionProfile::workspace_write()` as the reusable symbolic
  workspace-write helper, with docs noting that `:project_roots` entries
  resolve at enforcement time.
  - Updates app-server docs/examples and approval UI labeling to stop
  advertising `:cwd` as a permission token.
  
  ## Compatibility
  
  Persisted rollout items may contain the old
  `{"kind":"current_working_directory"}` tag from earlier experimental
  `permissionProfile` snapshots. This PR keeps that tag as a
  deserialize-only alias for `ProjectRoots { subpath: None }`, while
  continuing to serialize only the new `project_roots` tag.
  
  ## Follow-up
  
  This PR intentionally does not introduce an explicit project-root set on
  `SessionConfiguration` or runtime sandbox resolution. Today, the
  resolver still uses the active cwd as the single implicit project root.
  A follow-up should model project roots separately from tool cwd so
  `:project_roots` entries can resolve against the configured project
  roots, and resolve to no entries when there are no project roots.

• Preserve TUI markdown list spacing after code blocks (#19706)

  ## Why
  
  Fixes #19702.
  
  The TUI markdown renderer could visually attach the next list marker to
  a fenced code block inside the previous list item, even when the source
  markdown included a blank line before the next item. That made
  block-heavy loose lists harder to read, while the desired behavior is
  still to keep simple lists compact.
  
  ## What changed
  
  - Track whether the current rendered list item contains a code block.
  - Preserve one blank separator before the following list marker only
  when the previous item contained a code block.
  - Add regression coverage for both paths: code-block list items keep the
  separator, and simple loose list items stay compact.
  
  ## Verification
  
  - `cargo test -p codex-tui markdown_render`
  
  I also manually verified that the bug exists before and is fixed after.

• Delay approval prompts while typing (#19513)

  ## Why
  
  Fixes #7744. Approval modals can currently appear while the user is
  typing ahead in the TUI composer, which lets plain letters like `y` or
  `a` get consumed as approval shortcuts instead of staying in the draft
  input.
  
  ## What changed
  
  - Track recent composer typing activity in `bottom_pane/mod.rs`.
  - Delay new approval overlays for 1 second while the composer is active,
  keeping delayed requests queued until the user is idle.
  - Preserve the existing active-overlay behavior so approvals that arrive
  while an approval modal is already open are still queued into that
  overlay.
  - Prune delayed approvals when app-server resolution says the request
  has already been handled.
  
  ## Verification
  
  Added unit coverage for immediate approvals, delayed approvals, idle
  deadline reset, typed shortcut letters staying in the composer, shortcut
  handling after the delay, and resolved delayed-request pruning.
  
  Focused `codex-tui` test groups pass locally. The full `cargo test -p
  codex-tui` run currently aborts in
  `app::tests::attach_live_thread_for_selection_rejects_unmaterialized_fallback_threads`;
  that same test also fails when run alone with the same stack overflow.
  
  Manual reviewer check:
  
  1. Start the TUI from the repo root:
  
     ```bash
     RUST_LOG=trace just codex \
       -c log_dir=<temp-log-dir> \
       --ask-for-approval untrusted \
       --sandbox workspace-write
     ```
  
  2. Submit this prompt:
  
     ```text
     create a file text.txt on my desktop
     ```
  
  3. While the agent is preparing the approval request, immediately type
  text such as `ya this should stay in the composer`.
  4. Confirm the typed-ahead `y`/`a` remains in the composer instead of
  approving the request.
  5. Stop typing for about 1 second; the approval modal should then
  appear.
  6. Once the modal is visible, press `y` and confirm the approval
  shortcut works normally.

• Fix filtered thread-list resume regression in TUI (#19591)

  ## Why
  
  `codex resume` regressed after
  [#18502](https://github.com/openai/codex/pull/18502) changed the default
  `thread/list` scan-and-repair path for metadata-filtered listings. The
  TUI resume picker uses `thread/list` with source/provider/cwd filters
  and `useStateDbOnly: false`, which is the intended
  correctness-preserving mode: it should still consult the filesystem so
  healthy, missing, or stale SQLite state can be repaired.
  
  The regression was that #18502 made that filtered, filesystem-backed
  path call `reconcile_rollout` for every filesystem hit, and then call it
  again for each SQLite hit. When `reconcile_rollout` does not already
  have extracted rollout items, it falls back to loading the full JSONL
  rollout. That changed the resume picker’s first page from a cheap
  rollout-head scan plus SQLite read-repair into full-file reads for large
  sessions, so a few long threads could dominate TUI startup/resume
  latency.
  
  This change addresses the regression by keeping `useStateDbOnly: false`
  on the correctness-preserving path while avoiding unnecessary full JSONL
  reads for rows the filesystem scan has already validated.
  Source/provider/cwd filters can be decided from rollout-head metadata,
  so non-search resume listings only need the lightweight read-repair path
  for filesystem hits. Full reconciliation is still used for DB-only
  filtered rows because those can be stale false positives, and for search
  listings because search can depend on title metadata that may require
  scanning the full rollout.
  
  This fixes #19483.
  
  ## What changed
  
  - For non-search filtered listings, repair filesystem hits with the
  lightweight `read_repair_rollout_path` path instead of full
  `reconcile_rollout`.
  - Track thread IDs proven by the filesystem scan and only fully
  reconcile SQLite-filtered hits that the filesystem scan did not return,
  preserving stale-DB false-positive cleanup without full-reading every
  healthy rollout.
  - Leave search listings on full reconciliation, since search depends on
  full title metadata rather than only source/provider/cwd metadata from
  the rollout head.
  
  ## Verification
  
  - `cargo test -p codex-rollout list_threads`
  - `cargo test -p codex-app-server thread_list`

  budget so large images cannot inflate local context accounting without
  bound. Add regression coverage for an over-budget image.
  
  Fixes openai/codex#19806.

• fix: filter dynamic deferred tools from model_visible_specs (#19771)

  fixes #19486
  
  ### Problem
  Right now dynamic deferred tools are filtered at normal-turn prompt
  building time, rather than upstream while building the `ToolRouter`
  itself. This causes issues because dynamic deferred tools are then
  wrongly included in the router's `model_visible_specs`, which is what
  the compaction request-building flow relies on.
  
  ### Fix
  Move the dynamic deferred tool filtering to `ToolRouter` creation time
  to solve this problem for every request that relies on `ToolRouter` for
  `model_visible_specs`, which solves the issue generically.
  
  ### Tests
  Added unit + integration tests to ensure dynamic deferred tools are
  omitted from `model_visible_specs` and compaction request respectively.
  
  Tested against live `/compact` endpoint; raw deferred dynamic tools
  without `tool_search` returned `400` (current bug), while the filtered
  payload (this fix) returns `200`.

• Streamline account and command handlers (#19491)

  ## Why
  
  Account login/logout and command exec handlers were doing local error
  sends in the middle of each handler. That made these request flows
  branch heavily even though most of the logic is validate, perform the
  operation, and return the response.
  
  ## What Changed
  
  - Converted ChatGPT/API-key login, login cancel, logout, rate-limit, and
  add-credit handlers in
  `codex-rs/app-server/src/codex_message_processor.rs` to compute `Result`
  values and send them once at the request boundary.
  - Applied the same shape to command exec start/write/resize/terminate
  handlers.
  - Kept side-effect notifications in the same places after successful
  request handling.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::account --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::command_exec --
  --test-threads=1`

• ci: migrate Bazel setup away from archived setup-bazelisk (#19851)

  ## Why
  
  All Bazel CI jobs are currently blocked in the `setup-bazelisk` step
  while trying to download Bazelisk.
  [`bazelbuild/setup-bazelisk`](https://github.com/bazelbuild/setup-bazelisk)
  is archived, and its README now recommends migrating to
  [`bazel-contrib/setup-bazel`](https://github.com/bazel-contrib/setup-bazel),
  so leaving our workflows on the archived action leaves CI exposed to
  exactly this sort of outage.
  
  Because `v8-canary` now consumes the shared local `setup-bazel-ci`
  action, that workflow also needs to trigger when the action changes.
  Without that follow-up, Bazel bootstrap regressions specific to the V8
  canary path could be skipped by the workflow path filters.
  
  ## What Changed
  
  - Switched `.github/actions/setup-bazel-ci/action.yml` from
  `bazelbuild/setup-bazelisk` to `bazel-contrib/setup-bazel`, pinned to
  `0.19.0`.
  - Left `bazelisk-version` unset so GitHub-hosted runners can use their
  preinstalled Bazelisk instead of downloading `1.x` at job start.
  - Updated `.github/workflows/rusty-v8-release.yml` and
  `.github/workflows/v8-canary.yml` to use the shared `setup-bazel-ci`
  action instead of referencing `setup-bazelisk` directly.
  - Added `.github/actions/setup-bazel-ci/**` to the `pull_request` and
  `push` path filters in `.github/workflows/v8-canary.yml` so changes to
  the shared Bazel setup action still run the canary workflow.
  - Kept the existing repository-cache and Windows-specific Bazel setup
  logic intact.
  
  This keeps Bazel version selection anchored by `.bazelversion` while
  removing the failing dependency on the archived setup action.
  
  ## Verification
  
  - Searched `.github/` to confirm there are no remaining `setup-bazelisk`
  references.
  - Parsed the updated workflow and action YAML locally with Ruby's
  `YAML.load_file`.

• ci: pin npm staging smoke test to a recent rust-release run (#19854)

  ## Why
  
  The `build-test` workflow stages a representative `codex` npm tarball by
  asking `scripts/stage_npm_packages.py` to look up a past `rust-release`
  run for a hardcoded release version. That started failing in CI because
  the representative version in `.github/workflows/ci.yml` was stale:
  
  - the workflow was still using `0.115.0`
  - `stage_npm_packages.py` resolves native artifacts by looking for a
  `rust-release` run on the `rust-v<version>` branch
  - that lookup no longer found a matching run for `rust-v0.115.0`, so the
  smoke test failed before it could stage the package
  
  This PR makes that smoke test depend on a known-good recent release run
  instead of an older branch lookup that is no longer reliable.
  
  ## What Changed
  
  - Updated the representative release version in
  `.github/workflows/ci.yml` from `0.115.0` to `0.125.0`.
  - Added an explicit `WORKFLOW_URL` pointing at a recent successful
  `rust-release` run:
  `https://github.com/openai/codex/actions/runs/24901475298`.
  - Passed that URL to `scripts/stage_npm_packages.py` via
  `--workflow-url` so the job can reuse the expected native artifacts
  directly instead of relying on `gh run list --branch rust-v<version>` to
  discover them.
  
  That keeps the npm staging smoke test representative while making it
  less sensitive to older release branch history disappearing from the
  GitHub Actions lookup path.
  
  ## Verification
  
  - Inspected the failing CI log from `build-test` and confirmed the
  failure came from `scripts/stage_npm_packages.py` being unable to
  resolve `rust-v0.115.0`.
  - Confirmed that
  `https://github.com/openai/codex/actions/runs/24901475298` is a
  successful `rust-release` run for `rust-v0.125.0`.

• 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.

• Streamline plugin, apps, and skills handlers (#19490)

  ## Why
  
  The plugin, app, and skills handlers had a lot of repeated
  `send_error`/`return` branches that made the success path hard to scan.
  This slice keeps behavior the same while moving fallible steps into
  local response-producing helpers, so the request boundary can send one
  result.
  
  ## What Changed
  
  - Converted plugin list/install/uninstall handlers in
  `codex-rs/app-server/src/codex_message_processor/plugins.rs` to return
  `Result<*Response, JSONRPCErrorError>` from helper methods and call
  `send_result` once.
  - Added local error-mapping helpers for plugin install/uninstall and
  marketplace failures.
  - Applied the same mechanical shape to app list, skills list/config, and
  marketplace add/remove/upgrade handlers in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::app_list --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::plugin_ --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::skills_list --
  --test-threads=1`

• Render delegated patch approval details (#19709)

  ## Why
  
  Fixes #19632.
  
  When a delegated agent requests approval for an in-progress file change,
  the parent TUI handles that request from an inactive thread. The app
  server already sent the `FileChange` item with the proposed diff, but
  the inactive-thread approval path was not recovering and rendering it
  the same way as the active-thread path.
  
  The result was an inconsistent approval prompt: main-thread edits show a
  normal patch preview history item before the approval modal, while
  delegated edits did not show that preview in the transcript flow.
  
  ## What Changed
  
  - Recover buffered or historical `FileChange` item changes when building
  inactive-thread file-change approval requests.
  - Reuse the app-server file-change conversion helper for both live
  transcript rendering and inactive-thread approvals.
  - Render recovered delegated patches as a normal patch preview history
  cell before the approval modal.
  - Keep apply-patch approval modals focused on the decision prompt and
  optional metadata; they do not render a synthetic command line or embed
  the diff body.
  
  ## Manual Repro And Verification
  
  I manually reproduced the issue using a file under `~/Desktop` so the
  write would require approval.
  
  Before the fix:
  
  1. Ask the main thread: `Use apply_patch, not shell redirection or
  Python, to create ~/Desktop/bug1.txt with three short lines.`
  2. Observe the expected TUI shape: the transcript shows a normal patch
  preview such as `• Added ~/Desktop/bug1.txt (+N -0)` above the approval
  modal, and the modal contains only the approval prompt/options without a
  synthetic command line.
  3. Ask for the delegated path: `Spawn a worker. Have it use apply_patch,
  not shell redirection or Python, to create ~/Desktop/bug1.txt with four
  short lines.`
  4. Observe the delegated approval is inconsistent: the parent view does
  not render the proposed patch as the normal transcript preview before
  the modal, so the diff context is missing from the stream or appears
  inside the modal instead of in the history flow.
  
  After the fix:
  
  1. Repeat the delegated worker prompt with `apply_patch`.
  2. Confirm the parent view renders the same normal patch preview history
  cell (`• Added ~/Desktop/bug1.txt (+N -0)` plus the diff) immediately
  before the approval modal.
  3. Confirm the approval modal remains focused on the decision prompt.
  For delegated approvals it may show the worker thread label, but it
  should not show a `$ apply_patch` command line or embed the diff body in
  the modal.

• Persist shell mode commands in prompt history (#19618)

  ## Why
  
  `!` shell commands are currently surfaced as "Bash mode", which is
  misleading for users running shells such as PowerShell or zsh. Those
  commands also bypass the persistent prompt history path, so they cannot
  be recalled after starting a new session.
  
  Fixes #19613.
  
  ## What changed
  
  - Rename the TUI footer label and related test wording from "Bash mode"
  to "Shell mode".
  - Persist accepted `!` shell commands to prompt history with the leading
  `!`, so recall restores the composer into shell mode across sessions.
  - Add coverage for immediate and queued shell-command submissions
  emitting the prompt-history update.
  
  ## Verification
  
  - `cargo test -p codex-tui bang_shell`
  - `cargo test -p codex-tui shell_command_uses_shell_accent_style`
  - `cargo test -p codex-tui footer_mode_snapshots`
  - `cargo insta pending-snapshots --manifest-path tui/Cargo.toml`
  
  Manually verified fix after confirming presence of bug prior to fix.

• Hide rewind preview when no user message exists (#19510)

  ## Why
  
  Fixes #19508.
  
  In a fresh TUI session, pressing `Esc` twice entered the rewind
  transcript overlay even though there was no user message to rewind to.
  That produced an empty header-only transcript view and exposed a rewind
  flow that could not select a valid target.
  
  ## What changed
  
  The backtrack flow now checks whether a user-message rewind target
  exists before opening the transcript preview. If no target exists, Codex
  stays in the main TUI and shows `No previous message to edit.` instead
  of opening an empty overlay.
  
  The same guard applies when starting rewind preview from the transcript
  overlay, and the first `Esc` no longer advertises the “edit previous
  message” hint when there is no previous message available.
  
  Snapshot coverage was added for the unavailable rewind info message,
  along with a small target-detection test.
