• Add forked_from_thread_id turn metadata (#24160)

  ## Why
  
  When Codex calls responsesapi, we currently send `session_id`,
  `thread_id`, and `turn_id` among other things as
  `client_metadata["x-codex-turn-metadata"]`. This PR adds
  `forked_from_thread_id` which helps explain the "lineage" of a forked
  thread.
  
  ## What's changed
  
  - Track the immediate history source copied into a forked thread through
  thread/session creation, including subagent and review turn metadata
  paths.
  - Include `forked_from_thread_id` in Codex turn metadata while
  preventing turn-scoped Responses API client metadata from overwriting
  Codex-owned lineage fields.
  - Add coverage for fork lineage in turn metadata and the app-server
  Responses API request path.

• Avoid config snapshots in live agent subtree traversal (#24057)

  ## Why
  `/feedback` asks `ThreadManager` for the selected agent subtree before
  it uploads logs. The previous live subtree path reconstructed
  parent-child links by iterating every loaded thread and awaiting each
  thread config snapshot, so unrelated loaded-thread state could stall
  feedback subtree enumeration.
  
  The loaded-thread set already belongs to
  [`ThreadManagerState`](https://github.com/openai/codex/blob/50e6644c9425df2dcbfe52f65fd60bd7f15a8ea2/codex-rs/core/src/thread_manager.rs).
  Reading thread-spawn parents from the captured `CodexThread` session
  sources at that boundary keeps unload and resume behavior manager-owned
  while avoiding per-session config inspection.
  
  ## What Changed
  - expose parent-child thread-spawn edges for loaded, non-internal
  threads from `ThreadManagerState`
  - build the live child map from those edges while keeping agent metadata
  lookup and ordering in `AgentControl`
  - add regression coverage for live subtree enumeration when no state DB
  is available
  
  ## Validation
  - `git diff --check`
  - local Rust tests not run per request

• Make extension lifecycle hooks async (#23291)

  ## Why
  
  Extension lifecycle hooks sit on the host/extension boundary, but the
  current trait surface only allows synchronous callbacks. That forces
  extensions that need to seed, rehydrate, observe, or flush
  extension-owned state during thread and turn transitions to either block
  inside the callback or move async work into separate host plumbing.
  
  This PR makes those lifecycle callbacks awaitable so extension
  implementations can perform async work directly at the lifecycle point
  where the host already has the relevant session, thread, or turn stores
  available.
  
  ## What changed
  
  - Makes `ThreadLifecycleContributor` and `TurnLifecycleContributor`
  async in `codex-extension-api`.
  - Awaits thread start/resume/stop and turn start/stop/abort lifecycle
  callbacks from `codex-core`.
  - Updates the guardian and memories extensions to implement the async
  lifecycle trait surface.
  - Updates the existing lifecycle tests to use async contributor
  implementations.
  - Adds `async-trait` to the crates that now expose or implement these
  async object-safe lifecycle traits.
  
  ## Testing
  
  - Existing `codex-core` lifecycle tests were updated to cover async
  implementations for thread stop and turn abort ordering.

• feat: add thread lifecycle contributor hooks (#22476)

  ## Why
  
  Extensions that need thread-scoped state currently only get a start-time
  callback. That is enough for seeding stores, but it leaves the host
  without a shared extension seam for later thread rehydrate and flush
  work as thread ownership evolves. This PR turns that start-only seam
  into a host-owned thread lifecycle contributor contract so
  extension-private state can stay behind the extension API instead of
  leaking extra orchestration through core.
  
  ## What changed
  
  - Replaced `ThreadStartContributor` with `ThreadLifecycleContributor`
  and added typed lifecycle inputs for thread start, resume, and stop. The
  contract lives in
  [`contributors/thread_lifecycle.rs`](https://github.com/openai/codex/blob/d0e9211f70e58d6b07ef07e84f359d1b9aa25955/codex-rs/ext/extension-api/src/contributors/thread_lifecycle.rs#L1-L64).
  - Kept the existing start-time behavior intact by routing session
  construction through `on_thread_start`.
  - Invoked `on_thread_stop` during session shutdown before thread-scoped
  extension state is dropped, while isolating contributor failures behind
  warning logs.
  - Migrated `git-attribution` and `guardian` onto the lifecycle
  registration path.
  - Renamed the extension registry plumbing from start-specific
  contributors to lifecycle-specific contributors.
  
  ## Notes
  
  `on_thread_resume` is introduced at the API boundary here so extensions
  can target the final lifecycle shape; host resume dispatch can be wired
  where that runtime path is finalized.

• Unify thread metadata updates above store (#22236)

  - make ThreadStore::update_thread_metadata accept a broad range of
  metadata patches
  - keep ThreadStore::append_items as raw canonical history append (no
  metadata side effects)
  - in the local store, write these metadata updates to a combination of
  sqlite and rollout jsonl files for backwards-compat. It special cases
  which fields need to go into jsonl vs sqlite vs whatever, confining the
  awkwardness to just this implementation
  - in remote stores we can simply persist the metadata directly to a
  database, no special casing required.
  - move the "implicit metadata updates triggered by appending rollout
  items" from the RolloutRecorder (which is local-threadstore-specific) to
  the LiveThread layer above the ThreadStore, inside of a private helper
  utility called ThreadMetadataSync. LiveThread calls ThreadStore
  append_items and update_metadata separately.
  - Add a generic update metadata method to ThreadManager that works on
  both live threads and "cold" threads
  - Call that ThreadManager method from app server code, so app server
  doesn't need to worry about whether the thread is live or not

• extension: wire extension registries into sessions (#21737)

  ## Why
  
  [#21736](https://github.com/openai/codex/pull/21736) introduces the
  typed extension API, but the runtime does not yet carry a registry
  through thread/session startup or give contributors host-owned stores to
  read from. This PR wires that host-side path so later feature migrations
  can move product-specific behavior behind typed contributions without
  adding another bespoke seam directly to `codex-core`.
  
  ## What changed
  
  - Thread `ExtensionRegistry<Config>` through `ThreadManager`,
  `CodexSpawnArgs`, `Session`, and sub-agent spawn paths.
  - Wire `ThreadStartContributor` and `ContextContributor`
  - Expose the small supporting surface needed by non-core callers that
  construct threads directly, including `empty_extension_registry()`
  through `codex-core-api`.
  
  This PR lands the host plumbing only: the app-server registry is still
  empty, and concrete feature migrations are intended to follow
  separately.

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

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

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

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

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

• [codex] Remove remote thread store implementation (#21596)

  Remove the remote thread-store backend and checked-in protobuf
  artifacts. We've moved these into another crate that link against this
  one.
  
  Also remove the config settings for thread store backend selection,
  since we'll instead pass an instantiated thread store into the core-api

• Revert state DB injection and agent graph store (#21481)

  ## Why
  
  Reverts #20689 to restore the previous optional state DB plumbing. The
  conflict resolution keeps the newer installation ID and session/thread
  identity changes that landed after #20689, while removing the mandatory
  state DB and agent graph store dependency from ThreadManager
  construction.
  
  ## What changed
  
  - Restored `Option<StateDbHandle>` through app-server, MCP server,
  prompt debug, and test entry points.
  - Removed the `codex-core` dependency on `codex-agent-graph-store` and
  reverted descendant lookup back to the existing state DB path when
  available.
  - Kept newer `installation_id` forwarding by passing it beside the
  optional DB handle.
  - Kept local thread-name updates working when the optional state DB
  handle is absent.

• Move skills watcher to app-server (#21287)

  ## Why
  
  Skills update notifications are app-server API behavior, but the watcher
  lived in `codex-core` and surfaced through
  `EventMsg::SkillsUpdateAvailable`. Moving the watcher out keeps core
  focused on thread execution and lets app-server own both cache
  invalidation and the `skills/changed` notification.
  
  ## What changed
  
  - Added an app-server-owned skills watcher that watches local skill
  roots, clears the shared skills cache, and emits `skills/changed`
  directly.
  - Registers skill watches from the common app-server thread listener
  attach path, including direct starts, resumes, and app-server-observed
  child or forked threads.
  - Stores the `WatchRegistration` on `ThreadState`, so listener
  replacement, thread teardown, idle unload, and app-server shutdown
  deregister by dropping the RAII guard.
  - Removed `EventMsg::SkillsUpdateAvailable`, the core watcher, and the
  old core live-reload test.
  - Extended the app-server skills change test to verify a cached skills
  list is refreshed after a filesystem change without forcing reload.
  
  ## Validation
  
  - `cargo check -p codex-core -p codex-app-server -p codex-mcp-server -p

• Move installation ID resolution out of core startup (#21182)

  ## Summary
  
  - resolve or inject the installation ID before core startup and pass it
  through `ThreadManager`, `CodexSpawnArgs`, and `Session` as a plain
  `String`
  - keep child sessions on the parent installation ID instead of
  rediscovering it inside core
  - propagate installation ID startup failures in `mcp-server` instead of
  panicking
  
  ## Why
  
  Core was still touching the filesystem on the session startup path to
  discover `installation_id`. This moves that work to the outer host
  boundary so core no longer depends on `codex_home` reads during session
  construction.

• Preserve session MCP config on refresh (#21055)

  # Overview
  MCP refreshes were rebuilding active threads from fresh disk-backed
  config only, which dropped thread-start session overlays such as
  app-injected MCP servers. This keeps refreshes current with disk config
  while preserving the thread-local config that only the active thread
  knows about.
  
  # Changes
  - Rebuild refreshed config per active thread using that thread's current
  `cwd`, rather than fanning out one app-server config to every thread.
  - Preserve each thread's `SessionFlags` layer while replacing reloadable
  config layers with freshly loaded config, then derive the MCP refresh
  payload from the rebuilt result.
  - Move MCP refresh orchestration into app-server so manual refreshes
  fail loudly while background refreshes remain best-effort, and route
  plugin-triggered refreshes through the same per-thread reload path.
  - Add regression coverage for session overlays, fresh project config,
  plugin-derived MCP config, current requirements, and strict vs
  best-effort refresh behavior.
  
  # Verification
  - Passed focused Rust coverage for the thread-config rebuild behavior
  and deferred MCP refresh flow, plus `cargo test -p codex-app-server
  --lib`.
  - Verified end to end in the Codex dev app against the locally built
  CLI: registered an MCP via thread config, verified that it could be used
  successfully before refresh, manually triggered MCP refresh, and
  verified that it continued to be available afterward.

• [codex-analytics] rework thread_source for thread analytics (#20949)

  ## Summary
  - make `thread_source` an explicit optional thread-level field on
  `thread/start`, `thread/fork`, and returned thread payloads
  - persist `thread_source` in rollout/session metadata so resumed live
  threads retain the original value
  - replace the old best-effort `session_source` -> `thread_source`
  mapping with an explicit caller-supplied analytics classification
  
  ## Why
  Before this change, analytics `thread_source` was populated by a
  best-effort mapping from `session_source`. `session_source` describes
  the runtime/client surface, not the actual thread-level origin, so that
  projection was not accurate enough to distinguish cases such as `user`,
  `subagent`, `memory_consolidation`, and future thread origins reliably.
  
  Making `thread_source` explicit keeps one thread-level analytics field
  while letting callers provide the real classification directly instead
  of recovering it indirectly from `session_source`.
  
  ## Impact
  For new analytics events, `thread_source` now reflects the explicit
  thread-level classification supplied by the caller rather than an
  inferred value derived from `session_source`. Existing protocol fields
  remain optional; callers that omit `threadSource` now produce `null`
  instead of a best-effort inferred value.

• Inject state DB, agent graph store (#20689)

  ## Why
  
  We want the agent graph store to be passed down the stack as a real
  dependency, the same way we already treat the thread store.
  
  This will let us inject the agent graph store as a real dependency and
  support implementations other than the local SQLite-backed one. Right
  now most code instantiates a state DB and an agent graph store
  just-in-time. Ideally, we would not depend on the state DB directly but
  only read through the higher-level interfaces.
  
  This change makes the dependency boundaries explicit and moves state DB
  initialization to process bootstrap instead of hiding it inside local
  store implementations.
  
  ## What changed
  
  - `ThreadManager` now requires a `StateDbHandle` and an
  `AgentGraphStore` at construction time instead of treating them as
  optional internals.
  - The local store constructors no longer lazily initialize SQLite.
  Callers now initialize the state DB once per process and use that shared
  handle to build:
    - `LocalThreadStore`
    - `LocalAgentGraphStore`
  - App bootstraps (`app-server`, `mcp-server`, `prompt_debug`, and the
  thread-manager sample) now initialize the state DB up front and inject
  the resulting handle down the stack.
  - `app-server` now consistently uses its process-scoped state DB handle
  instead of reopening SQLite or trying to recover it from loaded threads.
  - Device-key storage now reuses the shared state DB handle instead of
  maintaining its own lazy opener.
  - The thread archive / descendant traversal paths now use the injected
  `AgentGraphStore` instead of reaching through local
  thread-store-specific state.
  
  ## Verification
  
  - `cargo check -p codex-core -p codex-thread-store -p codex-app-server
  -p codex-mcp-server -p codex-thread-manager-sample --tests`

• state: pass state db handles through consumers (#20561)

  ## Why
  
  SQLite state was still being opened from consumer paths, including lazy
  `OnceCell`-backed thread-store call sites. That let one process
  construct multiple state DB connections for the same Codex home, which
  makes SQLite lock contention and `database is locked` failures much
  easier to hit.
  
  State DB lifetime should be chosen by main-like entrypoints and tests,
  then passed through explicitly. Consumers should use the supplied
  `Option<StateDbHandle>` or `StateDbHandle` and keep their existing
  filesystem fallback or error behavior when no handle is available.
  
  The startup path also needs to keep the rollout crate in charge of
  SQLite state initialization. Opening `codex_state::StateRuntime`
  directly bypasses rollout metadata backfill, so entrypoints should
  initialize through `codex_rollout::state_db` and receive a handle only
  after required rollout backfills have completed.
  
  ## What Changed
  
  - Initialize the state DB in main-like entrypoints for CLI, TUI,
  app-server, exec, MCP server, and the thread-manager sample.
  - Pass `Option<StateDbHandle>` through `ThreadManager`,
  `LocalThreadStore`, app-server processors, TUI app wiring, rollout
  listing/recording, personality migration, shell snapshot cleanup,
  session-name lookup, and memory/device-key consumers.
  - Remove the lazy local state DB wrapper from the thread store so
  non-test consumers use only the supplied handle or their existing
  fallback path.
  - Make `codex_rollout::state_db::init` the local state startup path: it
  opens/migrates SQLite, runs rollout metadata backfill when needed, waits
  for concurrent backfill workers up to a bounded timeout, verifies
  completion, and then returns the initialized handle.
  - Keep optional/non-owning SQLite helpers, such as remote TUI local
  reads, as open-only paths that do not run startup backfill.
  - Switch app-server startup from direct
  `codex_state::StateRuntime::init` to the rollout state initializer so
  app-server cannot skip rollout backfill.
  - Collapse split rollout lookup/list APIs so callers use the normal
  methods with an optional state handle instead of `_with_state_db`
  variants.
  - Restore `getConversationSummary(ThreadId)` to delegate through
  `ThreadStore::read_thread` instead of a LocalThreadStore-specific
  rollout path special case.
  - Keep DB-backed rollout path lookup keyed on the DB row and file
  existence, without imposing the filesystem filename convention on
  existing DB rows.
  - Verify readable DB-backed rollout paths against `session_meta.id`
  before returning them, so a stale SQLite row that points at another
  thread's JSONL falls back to filesystem search and read-repairs the DB
  row.
  - Keep `debug prompt-input` filesystem-only so a one-off debug command
  does not initialize or backfill SQLite state just to print prompt input.
  - Keep goal-session test Codex homes alive only in the goal-specific
  helper, rather than leaking tempdirs from the shared session test
  helper.
  - Update tests and call sites to pass explicit state handles where DB
  behavior is expected and explicit `None` where filesystem-only behavior
  is intended.

  the rollout metadata row exists before startup init returns.
  - `state_db::tests::try_init_waits_for_concurrent_startup_backfill`
  verifies startup waits for another worker to finish backfill instead of
  disabling the handle for the process.
  -
  `state_db::tests::try_init_times_out_waiting_for_stuck_startup_backfill`
  verifies startup does not hang indefinitely on a stuck backfill lease.
  -
  `tests::find_thread_path_accepts_existing_state_db_path_without_canonical_filename`
  verifies DB-backed lookup accepts valid existing rollout paths even when
  the filename does not include the thread UUID.
  -
  `tests::find_thread_path_falls_back_when_db_path_points_to_another_thread`
  verifies DB-backed lookup ignores a stale row whose existing path
  belongs to another thread and read-repairs the row after filesystem
  fallback.
  
  Focused coverage updated in `codex-core`:
  
  - `rollout_list_find::find_prefers_sqlite_path_by_id` now uses a
  DB-preferred rollout file with matching `session_meta.id`, so it still
  verifies that valid SQLite paths win without depending on stale/empty
  rollout contents.
  
  `cargo test -p codex-app-server thread_list_respects_search_term_filter
  -- --test-threads=1 --nocapture` was attempted locally but timed out
  waiting for the app-server test harness `initialize` response before
  reaching the changed thread-list code path.
  
  `bazel test //codex-rs/thread-store:thread-store-unit-tests
  --test_output=errors` was attempted locally after the thread-store fix,
  but this container failed before target analysis while fetching `v8+`
  through BuildBuddy/direct GitHub. The equivalent local crate coverage,
  including `cargo test -p codex-thread-store`, passes.
  
  A plain local `cargo check -p codex-rollout -p codex-app-server --tests`
  also requires system `libcap.pc` for `codex-linux-sandbox`; the
  follow-up app-server check above used `CODEX_SKIP_VENDORED_BWRAP=1` in
  this container.

• Prepare selected environment plumbing (#20669)

  ## Why
  This is a prep PR in the multi-environment process-tool stack. It
  separates ownership/config cleanup from the behavior change that teaches
  process tools to route by selected environment, so the follow-up PR can
  focus on model-facing `environment_id` behavior.
  
  ## Stack
  1. https://github.com/openai/codex/pull/20646 - `EnvironmentContext`
  rendering for selected environments
  2. https://github.com/openai/codex/pull/20669 - selected-environment
  ownership and tool config prep (this PR)
  3. https://github.com/openai/codex/pull/20647 - process-tool
  `environment_id` routing
  
  ## What Changed
  - keep the resolved turn environment list wrapped in
  `ResolvedTurnEnvironments` through `TurnContext` instead of unwrapping
  it back to a raw `Vec`
  - add `TurnContext::resolve_path_against` so cwd-relative path
  resolution has one shared helper
  - replace the old tool config boolean with `ToolEnvironmentMode::{None,
  Single, Multiple}`
  
  ## Testing
  - Tests not run locally; this prep refactor is covered by GitHub CI for
  the stack.

• Use selected turn environments for runtime context (#20281)

  ## Summary
  - make selected turn environments the source of truth for session
  runtime cwd and MCP runtime environment selection
  - keep local/no-selection fallback behavior intact
  - add coverage for duplicate selected environments, cwd resolution, and
  MCP runtime environment selection
  
  ## Validation
  - git diff --check
  - rustfmt was run on touched Rust files during the implementation
  workflow
  
  CI should provide the full Bazel/test signal.

  - Build one app-server process ThreadStore from startup config and share

• Add goal core runtime (4 / 5) (#18076)

  Adds the core runtime behavior for active goals on top of the model
  tools from PR 3.
  
  ## Why
  
  A long-running goal should be a core runtime concern, not something
  every client has to implement. Core owns the turn lifecycle, tool
  completion boundaries, interruptions, resume behavior, and token usage,
  so it is the right place to account progress, enforce budgets, and
  decide when to continue work.
  
  ## What changed
  
  - Centralized goal lifecycle side effects behind
  `Session::goal_runtime_apply(GoalRuntimeEvent::...)`.
  - Starts goal continuation turns only when the session is idle; pending
  user input and mailbox work take priority.
  - Accounts token and wall-clock usage at turn, tool, mutation,
  interrupt, and resume boundaries; `get_thread_goal` remains read-only.
  - Preserves sub-second wall-clock remainder across accounting boundaries
  so long-running goals do not drift downward over time.
  - Treats token budget exhaustion as a soft stop by marking the goal
  `budget_limited` and injecting wrap-up steering instead of aborting the
  active turn.
  - Suppresses budget steering when `update_goal` marks a goal complete.
  - Pauses active goals on interrupt and auto-reactivates paused goals
  when a thread resumes outside plan mode.
  - Suppresses repeated automatic continuation when a continuation turn
  makes no tool calls.
  - Added continuation and budget-limit prompt templates.
  
  ## Verification
  
  - Added focused core coverage for continuation scheduling, accounting
  boundaries, budget-limit steering, completion accounting, interrupt
  pause behavior, resume auto-activation, and wall-clock remainder
  accounting.

• Add agents.interrupt_message for interruption markers (#19351)

  ## Why
  
  Agent interruptions currently always persist a model-visible
  interrupted-turn marker before emitting `TurnAborted`. That marker is
  useful by default because it gives the next model turn context about a
  deliberately interrupted task, but some deployments need to suppress
  that history injection entirely while still keeping the client-visible
  interruption event.
  
  ## What changed
  
  - Add `[agents] interrupt_message = false` to disable the model-visible
  interrupted-turn marker.
  - Resolve the setting into `Config::agent_interrupt_message_enabled`,
  defaulting to `true` so existing behavior is unchanged.
  - Apply the setting to both live interrupted turns and interrupted fork
  snapshots.
  - Keep emitting `TurnAborted` even when the history marker is disabled.
  - Regenerate `core/config.schema.json` for the new
  `agents.interrupt_message` field.
  
  ## Testing
  
  - `cargo test -p codex-core load_config_resolves_agent_interrupt_message
  -- --nocapture`
  - `cargo test -p codex-core

• Make MultiAgentV2 interruption markers assistant-authored (#19124)

  ## Why
  
  `MultiAgentV2` follow-up messages are delivered to agents as
  assistant-authored `InterAgentCommunication` envelopes. When
  `followup_task` used `interrupt: true`, the interrupted-turn guidance
  was still persisted as a contextual user message, so model-visible
  history made a system-generated interruption boundary look
  user-authored.
  
  This keeps interruption guidance consistent with the rest of the v2
  inter-agent message stream while preserving the legacy marker shape for
  non-v2 sessions.
  
  ## What changed
  
  - Make `interrupted_turn_history_marker` feature-aware.
  - Record the interrupted-turn marker as an assistant `OutputText`
  message when `Feature::MultiAgentV2` is enabled.
  - Keep the existing user contextual fragment for non-v2 sessions.
  - Apply the same feature-aware marker to interrupted fork snapshots.
  - Add coverage for the live `followup_task` interrupt path and the
  helper-level v2 marker shape.
  
  ## Testing
  
  - `cargo test -p codex-core
  multi_agent_v2_followup_task_interrupts_busy_child_without_losing_message
  -- --nocapture`

• feat: let model providers own model discovery (#18950)

  ## Why
  
  `codex-models-manager` had grown to own provider-specific concerns:
  constructing OpenAI-compatible `/models` requests, resolving provider
  auth, emitting request telemetry, and deciding how provider catalogs
  should be sourced. That made the manager harder to reuse for providers
  whose model catalog is not fetched from the OpenAI `/models` endpoint,
  such as Amazon Bedrock.
  
  This change moves provider-specific model discovery behind
  provider-owned implementations, so the models manager can focus on
  refresh policy, cache behavior, picker ordering, and model metadata
  merging.
  
  ## What Changed
  
  - Introduced a `ModelsManager` trait with separate `OpenAiModelsManager`
  and `StaticModelsManager` implementations.
  - Added `ModelsEndpointClient` so OpenAI-compatible HTTP fetching lives
  outside `codex-models-manager`.
  - Moved `/models` request construction, provider auth resolution,
  timeout handling, and request telemetry into `codex-model-provider` via
  `OpenAiModelsEndpoint`.
  - Added provider-owned `models_manager(...)` construction so configured
  OpenAI-compatible providers use `OpenAiModelsManager`, while
  static/catalog-backed providers can return `StaticModelsManager`.
  - Added an Amazon Bedrock static model catalog for the GPT OSS Bedrock
  model IDs.
  - Updated core/session/thread manager code and tests to depend on
  `Arc<dyn ModelsManager>`.
  - Moved offline model test helpers into
  `codex_models_manager::test_support`.
  ## Metadata References
  
  The Bedrock catalog metadata is based on the official Amazon Bedrock
  OpenAI model documentation:
  
  - [Amazon Bedrock OpenAI
  models](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-openai.html)
  lists the Bedrock model IDs, text input/output modalities, and `128,000`
  token context window for `gpt-oss-20b` and `gpt-oss-120b`.
  - [Amazon Bedrock `gpt-oss-120b` model
  card](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-openai-gpt-oss-120b.html)
  lists the `bedrock-runtime` model ID `openai.gpt-oss-120b-1:0`, the
  `bedrock-mantle` model ID `openai.gpt-oss-120b`, text-only modalities,
  and `128K` context window.
  - [OpenAI `gpt-oss-120b` model
  docs](https://developers.openai.com/api/docs/models/gpt-oss-120b)
  document configurable reasoning effort with `low`, `medium`, and `high`,
  plus text input/output modality.
  
  The display names, default reasoning effort, and priority ordering are
  Codex-local catalog choices.
  
  ## Test Plan
  - Manually verified app-server model listing with an AWS profile:
  
  ```shell
  CODEX_HOME="$(mktemp -d)" cargo run -p codex-app-server-test-client -- \
    --codex-bin ./target/debug/codex \
    -c 'model_provider="amazon-bedrock"' \
    -c 'model_providers.amazon-bedrock.aws.profile="codex-bedrock"' \
    -c 'model_providers.amazon-bedrock.aws.region="us-west-2"' \
    model-list
  ```
  
  The response returned the Bedrock catalog with `openai.gpt-oss-120b-1:0`
  as the default model and `openai.gpt-oss-20b-1:0` as the second listed
  model, both text-only and supporting low/medium/high reasoning effort.

• [rollout_trace] Add debug trace reduction command (#18880)

  ## Summary
  
  Adds the debug CLI entry point for reducing recorded rollout traces.
  This gives developers a direct way to inspect whether the emitted trace
  stream reduces into the expected conversation/runtime model.
  
  ## Stack
  
  This is PR 5/5 in the rollout trace stack.
  
  - [#18876](https://github.com/openai/codex/pull/18876): Add rollout
  trace crate
  - [#18877](https://github.com/openai/codex/pull/18877): Record core
  session rollout traces
  - [#18878](https://github.com/openai/codex/pull/18878): Trace tool and

  - [#18879](https://github.com/openai/codex/pull/18879): Trace sessions
  and multi-agent edges
  - [#18880](https://github.com/openai/codex/pull/18880): Add debug trace
  reduction command
  
  ## Review Notes
  
  This PR is intentionally last: it depends on the trace crate, core
  recorder, runtime/tool events, and session/agent edge data all existing.
  The command should remain a debug/developer tool and avoid adding new
  runtime behavior.
  
  The useful review question is whether the CLI exposes the reducer in the
  smallest practical way for local inspection without turning the debug
  command into a supported user-facing workflow.

• [codex] Route live thread writes through ThreadStore (#18882)

  Begin migrating the thread write codepaths to ThreadStore.
  
  This starts using ThreadStore inside of core session code, not only in
  the app server code.
  
  Rework the interfaces around thread recording/persistence. We're left
  with the following:
  
  * `ThreadManager`: owns the process-level registry of loaded threads and
  handles cross-thread orchestration: start, resume, fork, lookup, remove,
  and route ops to running CodexThreads.
  * `CodexThread`: represents one loaded/running thread from the outside.
  It is the handle app-server and callers use to submit ops, inspect
  session metadata, and shut the thread down.
  * `LiveThread`: session-owned persistence lifecycle handle for one
  active thread. Core session code uses it to append rollout items,
  materialize lazy persistence, flush, shutdown, discard init-failed
  writers, and load that thread’s persisted history.
  * `ThreadStore`: storage backend abstraction. It answers “how are
  threads persisted, read, listed, updated, archived?” Local and remote
  implementations live behind this trait.
  * `LocalThreadStore`: local ThreadStore implementation. It owns the
  file/sqlite-specific details and keeps RolloutRecorder as a local
  implementation detail.
  
  This is a few too many Thread abstractions for my liking, but they do
  all represent different concepts / needs / layers.
  
  Migration note: in places where the core code explicitly requires a
  path, rather than a thread ID, throw an error if we're running with a
  remote store.
  
  Cover the new local live-writer lifecycle with focused tests and
  preserve app-server thread-start behavior, including ephemeral pathless
  sessions.

• [rollout_trace] Record core session rollout traces (#18877)

  ## Summary
  
  Wires rollout trace recording into `codex-core` session and turn
  execution. This records the core model request/response, compaction, and
  session lifecycle boundaries needed for replay without yet tracing every
  nested runtime/tool boundary.
  
  ## Stack
  
  This is PR 2/5 in the rollout trace stack.
  
  - [#18876](https://github.com/openai/codex/pull/18876): Add rollout
  trace crate
  - [#18877](https://github.com/openai/codex/pull/18877): Record core
  session rollout traces
  - [#18878](https://github.com/openai/codex/pull/18878): Trace tool and
  code-mode boundaries
  - [#18879](https://github.com/openai/codex/pull/18879): Trace sessions
  and multi-agent edges
  - [#18880](https://github.com/openai/codex/pull/18880): Add debug trace
  reduction command
  
  ## Review Notes
  
  This layer is the first live integration point. The important review
  question is whether trace recording is isolated from normal session
  behavior: trace failures should not become user-visible execution
  failures, and recording should preserve the existing turn/session
  lifecycle semantics.
  
  The PR depends on the reducer/data model from the first stack entry and
  only introduces the core recorder surface that later PRs use for richer
  runtime and relationship events.

  ## 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.

• [codex-analytics] add compaction analytics event (#17155)

  - event for compaction analytics
  - introduces thread-connection and thread metadata caches for data
  denormalization, expected to be useful for denormalization onto core
  emitted events in general
  - threads analytics event client into core (mirrors approved
  implementation in #16640)
  - denormalizes key thread metadata: thread_source, subagent_source,
  parent_thread_id, as well as app-server client and runtime metadata)
  - compaction strategy defaults to memento, forward compatible with
  expected prefill_compaction strategy

• 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.

• core: remove cross-crate re-exports from lib.rs (#16512)

  ## Why
  
  `codex-core` was re-exporting APIs owned by sibling `codex-*` crates,
  which made downstream crates depend on `codex-core` as a proxy module
  instead of the actual owner crate.
  
  Removing those forwards makes crate boundaries explicit and lets leaf
  crates drop unnecessary `codex-core` dependencies. In this PR, this
  reduces the dependency on `codex-core` to `codex-login` in the following
  files:
  
  ```
  codex-rs/backend-client/Cargo.toml
  codex-rs/mcp-server/tests/common/Cargo.toml
  ```
  
  ## What
  
  - Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by
  `codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`,
  `codex-protocol`, `codex-shell-command`, `codex-sandboxing`,
  `codex-tools`, and `codex-utils-path`.
  - Delete the `default_client` forwarding shim in `codex-rs/core`.
  - Update in-crate and downstream callsites to import directly from the
  owning `codex-*` crate.
  - Add direct Cargo dependencies where callsites now target the owner
  crate, and remove `codex-core` from `codex-rs/backend-client`.
