  • feat: Update plugin share settings with discoverability (#21637)
    Requires discoverability on plugin/share/updateTargets so the server can
    manage workspace link access consistently, including auto-adding the
    workspace principal for UNLISTED.
    
    Also rejects LISTED on share creation and blocks client-supplied
    workspace principals while preserving response parsing for LISTED.
  • Remove skills list extra roots (#21485)
    ## Summary
    - Remove `perCwdExtraUserRoots` / `SkillsListExtraRootsForCwd` from the
    `skills/list` app-server API.
    - Drop Rust app-server and `codex-core-skills` extra-root plumbing so
    skill scans are keyed by the normal cwd/user/plugin roots only.
    - Regenerate app-server schemas and update docs/tests that only existed
    for the removed extra-roots behavior.
    
    ## Validation
    - `just write-app-server-schema`
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-core-skills`
    - `just fix -p codex-app-server-protocol`
    - `just fix -p codex-core-skills`
    - `just fix -p codex-app-server`
    - `just fix -p codex-tui`
    
    ## Notes
    - `cargo test -p codex-app-server --test all skills_list` ran the edited
    skills-list cases, but the full filtered run ended on existing
    `skills_changed_notification_is_emitted_after_skill_change` timeout
    after a websocket `401`.
    - `cargo test -p codex-tui --lib` compiled the changed TUI callers, then
    failed two unrelated status permission tests because local
    `/etc/codex/requirements.toml` forbids `DangerFullAccess`.
    - Source-truth check found the OpenAI monorepo still has
    generated/app-server-kit mirror references to the removed field; those
    should be cleaned up when generated app-server types are synced or in a
    companion OpenAI cleanup.
  • [codex-analytics] plumb protocol-native review timing (#21434)
    ## Why
    
    We want terminal tool review analytics, but the reducer should not stamp
    review timing from its own wall clock.
    
    This PR plumbs review timing through the real protocol and app-server
    seams so downstream analytics can consume the emitter's timestamps
    directly. Guardian reviews keep their enriched `started_at` /
    `completed_at` analytics fields by deriving those legacy second-based
    values from the same protocol-native millisecond lifecycle timestamps,
    rather than sampling a separate analytics clock.
    
    ## What changed
    
    - add `started_at_ms` to user approval request payloads
    - add `started_at_ms` / `completed_at_ms` to guardian review
    notifications
    - preserve Guardian review `started_at` / `completed_at` enrichment from
    the protocol-native timing source
    - stamp typed `ServerResponse` analytics facts with app-server-observed
    `completed_at_ms`
    - thread the new timing fields through core, protocol, app-server, TUI,
    and analytics fixtures
    
    ## Verification
    
    - `cargo test -p codex-app-server outgoing_message --manifest-path
    codex-rs/Cargo.toml`
    - `cargo test -p codex-app-server-protocol guardian --manifest-path
    codex-rs/Cargo.toml`
    - `cargo test -p codex-tui guardian --manifest-path codex-rs/Cargo.toml`
    - `cargo test -p codex-analytics analytics_client_tests --manifest-path
    codex-rs/Cargo.toml`

  • feat(app-server, threadstore): Thread pagination APIs and ThreadStore contract (#21566)
    ## Why
    The goal of this PR is to align on app-server and `ThreadStore` API
    updates for paginating through large threads.
    
    
    #### app-server
    ##### `thread/turns/list`
    - Updates `thread/turns/list` to support `itemsView?: "notLoaded" |
    "summary" | "full" | null`, defaulting to `summary`.
    - Implements the current `thread/turns/list` behavior over the existing
    persisted rollout-history fallback:
      - `notLoaded` returns turn envelopes with empty `items`.
    - `summary` returns the first user message and final assistant message
    when available.
      - `full` preserves the existing full item behavior.
    
    Note that this method still uses the naive approach of loading the
    entire rollout file, and returns just the filtered slice of the data.
    Real pagination will come later by leveraging SQLite.
    
    ##### `thread/turns/items/list`
    - Adds the experimental `thread/turns/items/list` protocol, schema,
    dispatcher, and processor stub. The app-server currently returns
    JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
    
    #### ThreadStore
    - Adds the experimental `thread/turns/items/list` protocol, schema,
    dispatcher, and processor stub. The app-server currently returns
    JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
    - Adds `ThreadStore` contract types and stubbed methods for listing
    thread turns and listing items within a turn.
    - Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
    app-server API enums or lossy string status values into the store-facing
    turn contract.
    - Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
    app-server API enums or lossy string status values into the store-facing
    turn contract.
    
    This also sketches the storage abstraction we expect to need once turns
    are indexed/stored. In particular, `notLoaded` is useful only if
    ThreadStore can eventually list turn metadata without loading every
    persisted item for each turn.
    
    ## Validation
    
    - Added/updated protocol serialization coverage for the new request and
    response shapes.
    - Added app-server integration coverage for `thread/turns/list` default
    summary behavior and all three `itemsView` modes.
    - Added app-server integration coverage that `thread/turns/items/list`
    returns the expected unsupported JSON-RPC error when experimental APIs
    are enabled.
    - Added thread-store coverage that the default trait methods return
    `ThreadStoreError::Unsupported`.
    
    No developers.openai.com documentation update is needed for this
    internal experimental app-server API surface.
  • [codex] Fix pathless thread summaries (#21266)
    ## Summary
    
    Fix `getConversationSummary` so thread-id summaries work for stored
    threads that do not have a local rollout path, such as remote thread
    stores.
    
    The root cause was that `summary_from_stored_thread` returned `None`
    when `StoredThread.rollout_path` was absent, and
    `get_thread_summary_response_inner` treated that as an internal error.
    This made conversation-id lookups depend on a local-only field even
    though the thread store can address the thread by id.
  • Move thread name edits to ThreadStore (#21264)
    - Route live thread renames through `ThreadStore` metadata updates.
    - Read resumed thread names from store metadata with legacy local
    fallback preserved in the store.
  • app-server: refresh live threads from latest config snapshot (#21187)
    ## Why
    
    App-server config writes were leaving existing threads partially stale.
    After a config mutation, the app-server told each live thread to run
    `Op::ReloadUserConfig`, but that path only re-read the user
    `config.toml` layer. Settings that came from the app-server's
    materialized config snapshot did not propagate to existing threads until
    restart.
    
    This change prevent a FS access from `core` for CCA.
    
    ## What changed
    
    - add `CodexThread::refresh_runtime_config()` and
    `Session::refresh_runtime_config()` so the app-server can push a freshly
    rebuilt config snapshot into a live thread
    - rebuild the latest config with each thread's `cwd` after config
    mutations, then refresh the thread from that snapshot instead of asking
    it to reload only `config.toml`
    - keep session-static settings unchanged during refresh, while updating
    runtime-refreshable state such as the config layer stack,
    `tool_suggest`, and derived hook/plugin/skill state
    - keep `reload_user_config_layer()` as the file-backed fallback for
    legacy local reload flows, but route the shared refresh logic through
    the new runtime refresh path
    
    ## Testing
    
    - add a session test that verifies `refresh_runtime_config()` rebuilds
    hooks from refreshed config
    - add a session test that verifies runtime-refreshable fields update
    while session-static settings like `model` and `notify` stay unchanged

  • feat: Expose plugin share metadata in shareContext (#21495)
    Extends PluginSummary.shareContext with shareUrl and reader shareTargets
  • [codex] add account id to feedback uploads (#21498)
    ## Why
    
    Feedback uploads already carry auth-derived context like
    `chatgpt_user_id`, but they do not include the authenticated
    workspace/account id. Adding `account_id` makes feedback triage easier
    when a user can operate across multiple ChatGPT workspaces.
    
    ## What changed
    
    - emit auth-derived `account_id` into feedback tags in `app-server`
    before the feedback snapshot is uploaded
    - preserve that tag through `codex-feedback` upload tag assembly
    alongside the existing merge behavior for other tags
    - extend `codex-feedback` coverage to assert that snapshot-derived
    `account_id` is present in uploaded tags
    
    ## Verification
    
    - `cargo test -p codex-feedback
    upload_tags_include_client_tags_and_preserve_reserved_fields`
    - `cargo test -p codex-app-server --lib feedback_processor`
  • Show plugin hooks in plugin details (#21447)
    Supersedes the abandoned #19859, rebuilt on latest `main`.
    
    # Why
    
    PR #19705 adds discovery for hooks bundled with plugins, but `/plugins`
    still only shows skills, apps, and MCP servers. This follow-up makes
    bundled hooks visible in the same plugin detail view so users can
    inspect the full plugin surface in one place.
    
    We also need `PluginHookSummary` to populate Plugin Hooks in the app;
    `hooks/list` is not enough there because plugin detail needs to show
    hooks for disabled plugins too.
    
    # What
    
    - extend `plugin/read` with `PluginHookSummary` entries for bundled
    hooks
    - summarize plugin hooks while loading plugin details
    - render a `Hooks` row in the `/plugins` detail popup

  • 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.
    
    ## Validation
    
    - `git diff --check`
    - `cargo test -p codex-thread-store`
    - `cargo test -p codex-state -p codex-rollout -p

  • [codex] Parallelize skills list cwd loading (#21441)
    ## Summary
    - process `skills/list` cwd entries with bounded concurrency of 5
    - preserve the caller's requested cwd order in the response
    - add coverage that verifies response ordering remains stable
    
    ## Why
    Cold-start desktop traces showed that `skills/list` can dominate the
    shared config queue when it scans many workspace roots serially. The
    expensive work is largely independent per cwd, so the request was paying
    the sum of all cwd costs instead of the cost of the slowest bounded
    batch.
    
    ## Impact
    This keeps current request semantics intact while reducing the
    wall-clock time of large multi-root `skills/list` calls. That should
    also reduce how long later config-family requests, such as
    `plugin/list`, wait behind `skills/list` during startup.
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server`
    - `cargo test -p codex-app-server
    skills_list_preserves_requested_cwd_order`
  • [codex] allow shared config reads in app-server queue (#21340)
    ## Summary
    - add a shared-read serialization mode for global app-server request
    families
    - let consecutive leading shared reads for the same family run together
    while keeping exclusive requests ordered
    - mark only `skills/list`, `config/read` and `plugin/list` as shared
    reads for now
    
    ## Why
    `skills/list` and `plugin/list` are read-only config-family requests,
    but the app-server queue currently treats every config request as
    exclusive. That means one long `skills/list` can make a later
    `plugin/list` wait even though the two requests do not mutate config.
    
    This change keeps the existing queue order but lets adjacent reads
    overlap. If a write is already waiting, later reads still stay behind
    it, so writes do not starve.
    
    ## Scope
    This intentionally keeps the first pass narrow:
    - shared reads: `skills/list`, `plugin/list`
    - still exclusive: `plugin/install`, `marketplace/*`,
    `skills/config/write`, `config/*write`, `config/read`, and the rest of
    the config family
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server`
    - `just fix -p codex-app-server-protocol`
    - `just fix -p codex-app-server`
    
    ## Desktop verification
    I ran the dev desktop app against this branch's built binary with the
    existing UI timing logs enabled. The app did use
    `/Users/xli/code/codex_6/codex-rs/target/debug/codex`.
    
    The new scheduler behavior works, but this narrow change does not remove
    every cold-start delay: in the observed trace, an earlier exclusive
    `config/read` was already queued ahead of the later `skills/list` and
    `plugin/list` requests, so the page-open plugin requests still waited
    behind that earlier exclusive config-family request before they could
    run together.
    
    That means this PR is the scheduler primitive needed for shared reads,
    not the complete end-to-end latency fix by itself.
    
    ## Not run
    - full workspace test suite, because repo policy requires explicit
    approval before running it after touching `app-server-protocol`
  • Add compact lifecycle hooks (started by vincentkoc - external contrib) (#19905)
    Based on work from Vincent K -
    https://github.com/openai/codex/pull/19060
    
    <img width="1836" height="642" alt="CleanShot 2026-04-29 at 20 47 40@2x"
    src="https://github.com/user-attachments/assets/b647bb89-65fe-40c8-80b0-7a6b7c984634"
    />
    
    ## Why
    
    Compaction rewrites the conversation context that future model turns
    receive, but hooks currently have no deterministic lifecycle point
    around that rewrite. This adds compact lifecycle hooks so users can
    audit manual and automatic compaction, surface hook messages in the UI,
    and run post-compaction follow-up without overloading tool or prompt
    hooks.
    
    ## What Changed
    
    - Added `PreCompact` and `PostCompact` hook events across hook config,
    discovery, dispatch, generated schemas, app-server notifications,
    analytics, and TUI hook rendering.
    - Added trigger matching for compact hooks with the documented `manual`
    and `auto` matcher values.
    - Wired `PreCompact` before both local and remote compaction, and
    `PostCompact` after successful local or remote compaction.
    - Kept compact hook command input to lifecycle metadata: session id,
    Codex turn id, transcript path, cwd, hook event name, model, and
    trigger.
    - Made compact stdout handling consistent with other hooks: plain stdout
    is ignored as debug output, while malformed JSON-looking stdout is
    reported as failed hook output.
    - Added integration coverage for compact hook dispatch, trigger
    matching, post-compact execution, and the audited behavior that
    `decision:"block"` does not block compaction.
    
    ## Out of Scope
    
    - Hook-specific compaction blocking is not implemented;
    `decision:"block"` and exit-code-2 blocking semantics are intentionally
    unsupported for `PreCompact`.
    - Custom compaction instructions are not exposed to compact hooks in
    this PR.
    - Compact summaries, summary character counts, and summary previews are
    not exposed to compact hooks in this PR.
    
    ## Verification
    
    - `cargo test -p codex-hooks`
    - `cargo test -p codex-core
    manual_pre_compact_block_decision_does_not_block_compaction`
    - `cargo test -p codex-app-server hooks_list`
    - `cargo test -p codex-core config_schema_matches_fixture`
    - `cargo test -p codex-tui hooks_browser`
    
    ## Docs
    
    The developer documentation for Codex hooks should be updated alongside
    this feature to document `PreCompact` and `PostCompact`, the
    `manual`/`auto` matcher values, and the compact hook payload fields.

  • feat: Add marketplace source filtering and plugin share context (#21419)
    Adds marketplaceKinds to plugin/list for local, workspace-directory, and
    shared-with-me; omitted params keep default local plus gated global
    behavior, while explicit kinds are exact.
    
    Exposes shareContext on plugin summaries from local share mappings and
    remote workspace/shared responses, including remotePluginId and nullable
    creator metadata.
    
    Adds shared-with-me listing through /ps/plugins/workspace/shared,
    renames the workspace remote namespace to workspace-directory, and keeps
    direct remote read/share/install/update/delete paths gated by plugins
    rather than remote_plugin.
  • 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
    codex-rollout -p codex-rollout-trace`

  • [codex-analytics] emit tool item events from item lifecycle (#17090)
    ## Why
    
    After the tool-item schemas are in place, analytics needs to emit them
    from the app-server item lifecycle rather than requiring bespoke
    tracking at each callsite. The reducer should also reuse the shared
    thread analytics context introduced below it in the stack so later event
    families do not repeat the same reducer joins or missing-state ladder.
    
    ## What changed
    
    - Tracks tool-item completion notifications and emits the matching tool
    analytics event when a terminal item arrives.
    - Derives event-specific payload details for command execution, file
    changes, MCP calls, dynamic tools, collaboration tools, web search, and
    image generation.
    - Denormalizes thread, app-server client, runtime, and subagent
    provenance metadata through the shared thread analytics context.
    - Adds reducer coverage for item lifecycle emission and subagent
    metadata inheritance.
    
    ## Duration semantics
    
    `duration_ms` is computed from the app-server item lifecycle timestamps:
    `completed_at_ms - started_at_ms`. That makes it the duration of the
    lifecycle Codex observed locally, not necessarily the upstream
    provider's full execution time.
    
    - Web search usually has a meaningful observed lifecycle because
    Responses can send `response.output_item.added` before
    `response.output_item.done`; in that case `started_at_ms` comes from the
    added event and `completed_at_ms` comes from the done event.
    - Image generation can be much less precise. In the current observed
    stream, image generation often arrives only as a completed
    `response.output_item.done`; when there is no earlier added event, Codex
    synthesizes the started item immediately before completion, so
    `duration_ms` can be `0` even though upstream image generation took
    longer.
    - Standalone web search and standalone image generation work is expected
    to land after this stack. Those paths may introduce more direct
    lifecycle events or timing points, so the current
    web-search/image-generation duration semantics should be treated as the
    best available item-lifecycle approximation, not the final latency
    contract for those tool families.
    - `execution_duration_ms` is populated only where the completed item
    already carries a native execution duration; otherwise it remains `null`
    while `duration_ms` still reflects the local lifecycle interval.
    
    ## Currently placeholder / partial fields
    
    Some fields are included in the schema for the intended steady-state
    contract, but this PR does not yet populate them from real
    approval/review state:
    
    - `review_count`, `guardian_review_count`, and `user_review_count`
    currently default to `0`.
    - `final_approval_outcome` currently defaults to `unknown`.
    - `requested_additional_permissions` and `requested_network_access`
    currently default to `false`.

    - `cargo test -p codex-analytics`

  • feat(app-server): move v2 sessionId onto Thread (#21336)
    ## Why
    
    `session_id` and `thread_id` are separate identities after #20437, but
    app-server only surfaced `sessionId` on the `thread/start`,
    `thread/resume`, and `thread/fork` response envelopes. Other
    thread-bearing surfaces such as `thread/list`, `thread/read`,
    `thread/started`, `thread/rollback`, `thread/metadata/update`, and
    `thread/unarchive` either lacked the grouping key or forced clients to
    special-case those three responses.
    
    Making `sessionId` part of the reusable `Thread` payload gives every v2
    API surface one place to expose session-tree identity.
    
    ## Mental model
      1. thread.sessionId lives on `Thread`
    2. It is a view/runtime identity for the current live session tree, not
    durable stored lineage metadata
    3. When app-server has a live loaded thread, it copies the real value
    from core’s session_configured.session_id
    4. When it only has stored/unloaded data, it falls back to
    thread.sessionId = thread.id
    
    ## What changed
    
    - Added `sessionId` to the v2
    [`Thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server-protocol/src/protocol/v2/thread_data.rs#L105-L109).
    - Removed the duplicate top-level `sessionId` fields from
    `thread/start`, `thread/resume`, and `thread/fork`; clients should now
    read `response.thread.sessionId`.
    - Populated `thread.sessionId` when building live thread responses,
    replaying loaded threads, and returning stored-thread summaries so the
    field is present across start, resume, fork, list, read, rollback,
    metadata-update, unarchive, and `thread/started` paths. See
    [`load_thread_from_resume_source_or_send_internal`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L2824-L2918)
    and
    [`thread_from_stored_thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L3671-L3719).
    - Preserved the stored-thread fallback: if a thread has not been loaded
    into a live session tree yet, `thread.sessionId` falls back to
    `thread.id`; once the thread is live again, the field reports the active
    session tree root.
    - Regenerated the JSON/TypeScript schemas and updated the app-server
    README examples to show
    [`thread.sessionId`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/README.md#L306-L310)
    on the thread object.
  • 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.

  • feat: return session ID from thread/fork (#21332)
    ## Why
    
    `thread/start` and `thread/resume` already return `sessionId`, but
    `thread/fork` only returned the new thread. That left clients to infer
    the forked thread's session identity from `thread.id`, which kept the
    new `session_id` / `thread_id` split implicit at one lifecycle boundary.
    Follow-up to #20437.
    
    ## What changed
    
    - Add `sessionId` to `ThreadForkResponse`.
    - Populate it from the forked session configuration.
    - Regenerate the v2 JSON/TypeScript schema fixtures and update the
    app-server docs/example.
    - Extend the fork integration test to assert the returned `sessionId`.
    
    ## Verification
    
    - Added coverage in `thread_fork_creates_new_thread_and_emits_started`
    for the new response field.
  • feat: add session_id (#20437)
    ## Summary
    
    Related to
    https://openai.slack.com/archives/C095U48JNL9/p1777537279707449
    TLDR:
    We update the meaning of session ids and thread ids:
    * thread_id stays as now
    * session_id become a shared id between every thread under a /root
    thread (i.e. every sub-agent share the same session id)
    
    This PR introduces an explicit `SessionId` and threads it through the
    protocol/client boundary so `session_id` and `thread_id` can diverge
    when they need to, while preserving compatibility for older serialized
    `session_configured` events.

  • 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.
  • app-server: align dynamic tool identifiers with Responses API (#20724)
    ## Why
    
    Codex currently accepts dynamic tool names and namespaces that the
    upstream Responses function-tool path does not actually support. In
    practice, that means app-server can register a dynamic tool successfully
    and only discover later that the LLM-facing tool contract will reject or
    mishandle it.
    
    This PR tightens the app-server-side dynamic tool contract to match the
    Responses API before we stack dynamic tool hook support on top of it.
    
    ## What changed
    
    - validate dynamic tool `name` against the Responses function-tool
    identifier contract: `^[a-zA-Z0-9_-]+$`, length `1..128`
    - validate dynamic tool `namespace` the same way, with the Responses
    namespace length limit `1..64`
    - reject namespaces that collide with the always-reserved Responses
    runtime namespaces such as `functions`, `multi_tool_use`, `file_search`,
    `web`, `browser`, `image_gen`, `computer`, `container`, `terminal`,
    `python`, `python_user_visible`, `api_tool`, `tool_search`, and
    `submodel_delegator`
    - escape invalid identifiers in error messages so control characters do
    not spill raw into logs or client-visible error text
    - document the tightened dynamic tool identifier contract in
    `codex-rs/app-server/README.md`
    - add both unit coverage for the validator and an app-server integration
    test that rejects a `thread/start` request with Responses-incompatible
    dynamic tool identifiers
    
    ## Verification
    
    - `cargo test -p codex-app-server validate_dynamic_tools_`
    - `cargo test -p codex-app-server --test all

  • feat: Add plugin share access controls (#21124)

    re-uploading.
  • [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.

  • [codex] Move thread naming to app server (#21260)
    ## Why
    
    Thread names are app-server metadata now, backed by the thread store and
    sqlite state database. Keeping a core `SetThreadName` op plus a rollout
    `thread_name_updated` event made rename persistence live in the wrong
    layer and required historical replay support for an event that new
    app-server flows should not write.
    
    ## What changed
    
    - Removed `Op::SetThreadName` and `EventMsg::ThreadNameUpdated` from the
    core protocol and deleted the core handler path that appended rename
    events to rollouts.
    - Updated app-server `thread/name/set` so both loaded and unloaded
    threads write through thread-store metadata and app-server emits
    `thread/name/updated` notifications.
    - Updated local thread-store name metadata updates to write sqlite title
    metadata and the legacy thread-name index without appending rollout
    events.
    - Removed state extraction and rollout handling for the deleted
    thread-name event.

  • 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.

  • Auto-deny MCP elicitations for Xcode 26.4 clients (#21113)
    ## Summary
    
    Xcode 26.4 was built against app-server behavior from before MCP
    elicitation requests became client-visible in CLI 0.120.0 via #17043.
    That client line does not expect the new events/messages, so this PR
    restores the old behavior for exactly that client/version combination.
    
    The compatibility handling stays in the app-server layer: when the
    initialized client is `Xcode` and its version starts with `26.4`, the
    app server marks the live Codex thread so MCP elicitations are
    auto-denied. The flag is applied on thread start/resume/fork/turn
    attachment, carried through `Codex`/`CodexThread`, and stored on
    `McpConnectionManager` so refreshed MCP managers preserve the behavior.
    
    ## Notes
    
    This is intentionally narrow and includes a TODO to remove the
    compatibility path once Xcode 26.4 ages out.
  • add turn items view to app-server turns (#21063)
    ## Why
    
    `Turn.items` currently overloads an empty array to mean either that no
    items exist or that the server intentionally did not load them for this
    response. That ambiguity blocks future lazy-loading work where clients
    need to distinguish unloaded, summary, and fully hydrated turn payloads.
    
    ## What changed
    
    - add a new `TurnItemsView` enum with `notLoaded`, `summary`, and `full`
    variants
    - add required `itemsView` metadata to app-server `Turn` payloads
    - mark reconstructed persisted history as `full` and live shell-style
    turn payloads as `notLoaded`
    - keep current `thread/turns/list` behavior unchanged and document that
    it still returns `full` turns today

  • [codex] Use shared app-server JSON-RPC error helpers (#21221)
    ## Why
    
    App-server had repeated hand-built JSON-RPC error objects for standard
    error shapes. Using the shared helpers keeps the common
    `invalid_request`, `invalid_params`, and `internal_error` construction
    in one place and reduces the chance of new call sites drifting from the
    common error payload shape.
    
    ## What changed
    
    - Replaced manual standard JSON-RPC error object creation with
    `internal_error(...)`, `invalid_request(...)`, and `invalid_params(...)`
    across app-server request processors and runtime paths.
    - Removed local duplicate helper definitions from search and review
    request handling.
    - Preserved existing structured `data` payloads by creating the shared
    helper error first and then attaching the existing metadata.
    - Left custom non-standard errors and raw error-code assertions intact.
    
    ## Validation
    
    - `cargo test -p codex-app-server`
  • hook trust metadata and enforcement (#20321)
    # Why
    
    We want shared hook trust that both the app and the TUI can build on,
    but the metadata is only useful if runtime behavior agrees with it. This
    PR adds a single backend trust model for hooks so unmanaged hooks cannot
    run until the current definition has been reviewed, while managed hooks
    remain runnable and non-configurable.
    
    # What
    
    - persist `trusted_hash` alongside hook state in `config.toml`
    - expose `currentHash` and derived `trustStatus` through `hooks/list`
    - derive trust from normalized hook definitions so equivalent hooks from
    `config.toml` and `hooks.json` share the same trust identity
    - gate unmanaged hooks on trust before they enter the runnable handler
    set

  • app-server: ignore persist_extended_history param (#21225)
    ## Why
    
    Taking a step to removing the `persistExtendedHistory` field. It's not
    scalable to be persisting so much data in the rollout file and returning
    it in the thread history.
    
    When a client explicitly sends `true`, the server now tells that client
    the parameter is deprecated and ignored so the caller has a clear
    migration signal via the `deprecationNotice` notification.
    
    ## What changed
    
    - Keep the `persist_extended_history` / `persistExtendedHistory` field
    in the v2 protocol for compatibility, but document it as deprecated and
    ignored.
    - Ignore the parameter in app-server `thread/start`, `thread/resume`,
    and `thread/fork`; those paths always use limited history persistence
    now.
    - Stop treating `persistExtendedHistory` as a running-thread resume
    override mismatch.
    - Emit a connection-scoped `deprecationNotice` when a request explicitly
    sets `persist_extended_history: true`.
    
    ## Verification
    
    - Added `thread_start_deprecates_persist_extended_history_true` to cover
    the deprecation notice.

  • Add Windows sandbox readiness RPC (#20708)
    ## Why
    
    The desktop app on Windows needs a read-only way to tell, before the
    next tool call, whether the local Windows sandbox setup is in a state
    that should block the user and ask for setup again.
    
    The main case we want to cover is the elevated sandbox setup version
    bump. Today, if the app is configured for elevated Windows sandboxing
    and the installed setup is stale, the next sandboxed shell/exec path can
    end up triggering the elevated setup flow directly. That means the user
    can see an unexpected UAC prompt with no UI explanation.
    
    This change adds a small app-server preflight so the desktop app can ask
    “is Windows sandbox ready, not configured, or update-required?” during
    startup and show the appropriate blocking UI before the user hits a tool
    call.
    
    ## What changed
    
    - Added a new read-only app-server RPC: `windowsSandbox/readiness`
    - Added a new protocol enum and response type:
      - `WindowsSandboxReadiness`
      - `WindowsSandboxReadinessResponse`
    - Added core readiness logic in `core/src/windows_sandbox.rs`:
      - `ready`
      - `notConfigured`
      - `updateRequired`
    - Wired the new request through `codex_message_processor`
    - Regenerated the vendored app-server schema fixtures
    
    ## Readiness semantics
    
    This is intentionally a coarse startup/version-bump readiness check, not
    a full predictor of every runtime repair case.
    
    For now, readiness is determined from:
    - the configured Windows sandbox level
    - `sandbox_setup_is_complete()` for elevated mode
    
    That means:
    - `disabled` maps to `notConfigured`
    - `restricted token` maps to `ready`
    - `elevated` maps to `ready` or `updateRequired` depending on
    `sandbox_setup_is_complete()`
    
    This is deliberate for the first UI integration because the common case
    we want to catch is “the app updated, the elevated setup version bumped,
    and the user should see an update-required blocker instead of a surprise
    UAC prompt”.
    
    It does not attempt to model every case where the deeper runtime path
    might decide to repair or re-run setup.
    
    ## Testing
    
    - Ran `cargo fmt --all -- app-server-protocol/src/protocol/common.rs
    app-server-protocol/src/protocol/v2.rs
    app-server/src/codex_message_processor.rs core/src/windows_sandbox.rs
    core/src/windows_sandbox_tests.rs`
    - Added unit tests for the pure readiness mapping in
    `core/src/windows_sandbox_tests.rs`
    - Regenerated vendored schema fixtures with `cargo run -p
    codex-app-server-protocol --bin write_schema_fixtures -- --schema-root
    app-server-protocol/schema`
    - Did not run the full cargo test suite
  • Add goal lifecycle metrics (#20799)
    ## Why
    
    Adding goal metrics makes it possible to track how often goals are
    created, completed, and stopped by budget limits, plus the final token
    and wall-clock usage for terminal outcomes.
    
    ## What Changed
    
    - Added OpenTelemetry metric constants for goal lifecycle tracking:
    - `codex.goal.created`: increments each time a new persisted goal is
    created or an existing goal is replaced with a new objective.
    - `codex.goal.completed`: increments when a goal transitions to
    `complete`.
    - `codex.goal.budget_limited`: increments when a goal transitions to
    `budget_limited` because its token budget has been reached.
    - `codex.goal.token_count`: records the final persisted token count when
    a goal transitions to `complete` or `budget_limited`.
    - `codex.goal.duration_s`: records the final persisted elapsed
    wall-clock time, in seconds, when a goal transitions to `complete` or
    `budget_limited`.
    - Emitted creation metrics when a goal is created or replaced.
    - Emitted terminal outcome counters and final usage histograms when a
    goal transitions to `complete` or `budget_limited`, avoiding
    double-counting later in-flight accounting for already budget-limited
    goals.
    - Added focused `codex-core` tests for create/complete metrics and
    one-time budget-limit metrics.
  • 1- Add model service tiers metadata (#20969)
    ## Why
    
    The model list needs to carry display-ready service tier metadata so
    clients can render tier choices with stable IDs, names, and
    descriptions. A raw speed-tier string list is not enough for richer UI
    copy or future tier labels.
    
    ## What changed
    
    - Added `ModelServiceTier` to shared model metadata with string `id`,
    `name`, and `description` fields.
    - Added `service_tiers` to `ModelInfo` and `ModelPreset`, preserving
    empty defaults for older cached model payloads.
    - Exposed `serviceTiers` on app-server v2 `Model` responses and threaded
    it through TUI app-server model conversion.
    - Marked legacy `additional_speed_tiers` / `additionalSpeedTiers`
    metadata as deprecated in source and generated schema output.
    - Regenerated app-server protocol JSON schema and TypeScript fixtures,
    including `ModelServiceTier.ts`.
    
    ## Verification
    
    - Ran `just write-app-server-schema`.
    - Did not run local tests per repo instruction; relying on PR CI.

  • codex: migrate (more) app-server thread history reads to ThreadStore (#20575)
    Migrate token usage replay, rollback responses, and detached review
    setup (a special case of forking) to be served from ThreadStore reads
    rather direct rollout files.
    
    - replay restored token usage from already-loaded `RolloutItem` history
    instead of reopening `Thread.path`
    - rebuild rollback responses from loaded `ThreadStore` snapshots and
    history
    - start detached reviews from store-backed parent history and stored
    review-thread metadata
    - remove obsolete app-server rollout-summary helper code that became
    dead after the store-backed migration
    - preserve response/notification ordering for resume, fork, rollback,
    and detached review flows
    - add integration test coverage for the affected paths
  • codex: route metadata updates through ThreadStore (#20576)
    - Route `thread/metadata/update` through
    `ThreadStore::update_thread_metadata`.
    - Add `LocalThreadStore` git metadata patch support for set, partial
    update, and clear semantics.
    - Add some unit tests for the new thread store code
    - Remove a lot of dead code/tests!
  • [codex] Add unsandboxed process exec API (#19040)
    ## Why
    
    App-server clients sometimes need argv-based local process execution
    while sandbox policy is controlled outside Codex. Those environments can
    reject sandbox-disabling paths before a command ever starts, even when
    the caller intentionally wants unsandboxed execution.
    
    This PR adds a distinct `process/*` API for that use case instead of
    extending `command/exec` with another sandbox-disabling shape. Keeping
    the new surface separate also makes the future removal of `command/exec`
    simpler: clients that need explicit process lifecycle control can move
    to the newer handle-based API without depending on `command/exec`
    business logic.
    
    ## What changed
    
    - Added v2 process lifecycle methods: `process/spawn`,
    `process/writeStdin`, `process/resizePty`, and `process/kill`.
    - Added process notifications: `process/outputDelta` for streamed
    stdout/stderr chunks and `process/exited` for final exit status and
    buffered output.
    - Made `process/spawn` intentionally unsandboxed and omitted
    sandbox-selection fields such as `sandboxPolicy` and
    `permissionProfile`.
    - Added client-supplied, connection-scoped `processHandle` values for
    follow-up control requests and notification routing.
    - Supported cwd, environment overrides, PTY mode and size, stdin
    streaming, stdout/stderr streaming, per-stream output caps, and timeout
    controls.
    - Killed active process sessions when the originating app-server
    connection closes.
    - Wired the implementation through the modular `request_processors/`
    app-server layout, with process-handle request serialization for
    follow-up control calls.
    - Updated generated JSON/TypeScript schema fixtures and documented the
    new API in `codex-rs/app-server/README.md`.
    - Added v2 app-server integration coverage in
    `codex-rs/app-server/tests/suite/v2/process_exec.rs` for spawn
    acknowledgement before exit, buffered output caps, and process
    termination.

  • Remove remote plugin uninstall prefix gate (#20722)
    ## Summary
    
    Remove the hardcoded remote plugin ID prefix allow-list from app-server
    uninstall routing. IDs that do not parse as local `plugin@marketplace`
    IDs now flow through the remote uninstall path, where the existing
    remote ID safety validation still rejects empty IDs, spaces, slashes,
    and other unsafe characters before URL/cache use.
    
    ## Why
    
    Plugin-service owns the backend remote plugin ID contract. Codex should
    not require remote IDs to start with the local hardcoded prefixes
    `plugins~`, `plugins_`, `app_`, `asdk_app_`, or `connector_`, because
    newer backend ID families could otherwise be rejected before
    plugin-service sees the request.
    
    ## Validation
    
    - `just fmt`
    - `cargo test -p codex-app-server plugin_uninstall`
    - `just fix -p codex-app-server`
    - `git diff --check`
  • [codex-analytics] add item lifecycle timing (#20514)
    ## Why
    
    Tool families already disagree on what their existing `duration` fields
    mean, so lifecycle latency should live on the shared item envelope
    instead of being inferred from per-tool execution fields. Carrying that
    envelope through app-server notifications gives downstream consumers one
    reusable timing signal without pretending every tool has the same
    execution semantics.
    
    ## What changed
    
    - Adds `started_at_ms` to core `ItemStartedEvent` values and
    `completed_at_ms` to core `ItemCompletedEvent` values.
    - Populates those timestamps in the shared session lifecycle emitters,
    so protocol-native items get timing without each producer tracking its
    own clock state.
    - Exposes `startedAtMs` on app-server `item/started` notifications and
    `completedAtMs` on `item/completed` notifications.
    - Maps the lifecycle timestamps through the app-server boundary while
    leaving legacy-converted notifications nullable when no lifecycle
    timestamp exists.
    - Regenerates the app-server JSON schema and TypeScript fixtures for the
    notification-envelope change and updates downstream fixtures that
    construct those notifications directly.
    - Extends the existing web-search and image-generation integration flows
    to assert the new lifecycle timestamps on the native item events.
    
    ## Verification
    
    - `cargo check -p codex-protocol -p codex-core -p

  • 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.

    Focused coverage added in `codex-rollout`:

    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.
  • feat(app-server): always return limited thread history (#20682)
    ## Why
    
    Whenever we return a thread's history (turns and items) over app-server,
    always return the limited form as specified by the rollout policy
    `EventPersistenceMode::Limited`, even if the thread was previously
    started with `EventPersistenceMode::Extended`.
    
    We're finding it is quite unscalable to be returning the extended
    history, so let's apply the same filtering logic of the rollout policy
    when we load and return the thread's history.
    
    ## What Changed
    
    - Reuse the rollout persistence policy when reconstructing app-server
    `ThreadItem` history so only `EventPersistenceMode::Limited` rollout
    items are replayed into API turns.
    - Route `thread/read`, `thread/resume`, `thread/fork`,
    `thread/turns/list`, and rollback responses through the same filtered
    app-server history projection.
    - Keep live active turns intact when composing a response for a
    currently running thread.
    - Update command execution coverage so persisted extended command events
    are excluded from returned history for `thread/read`, `thread/fork`, and
    `thread/turns/list`.
    
    ## Test Plan

  • [codex] Split app-server request processors (#20940)
    ## Why
    
    The app-server request path had grown around a large
    `CodexMessageProcessor` plus separate API wrapper/helper modules. That
    made the dependency graph hard to see and forced unrelated request
    families to share broad processor state.
    
    This PR makes the split mechanical and command-prefix oriented so
    request families own only the dependencies they use.
    
    ## What changed
    
    - Replaced `CodexMessageProcessor` with command-prefix request
    processors under `app-server/src/request_processors/`.
    - Removed the old config, device-key, external-agent-config, and fs API
    wrapper files by moving their API handling into processors.
    - Split apps, plugins, marketplace, catalog, account, MCP, command exec,
    fs, git, feedback, thread, turn, thread goals, and Windows sandbox
    handling into dedicated processors.
    - Kept shared lifecycle, summary conversion, token usage replay, and
    shared error mapping only where multiple processors use them; single-use
    helpers were inlined into their owning processor.
    - Removed the fallback processor path and moved processor tests to
    `_tests` files.

  • [codex] Emit MCP tool calls as turn items (#20677)
    ## Why
    
    `McpToolCall` was still an app-server item synthesized from deprecated
    legacy begin/end events. Recent item migrations moved this ownership
    into core `TurnItem`s, so MCP tool calls now follow the same canonical
    lifecycle and leave legacy events as compatibility fanout.
    
    Keeping the core item close to the v2 `ThreadItem::McpToolCall` shape
    also avoids spreading MCP result semantics across app-server conversion
    code. Core now owns whether a completed call is `completed` or `failed`,
    and whether the payload is a tool result or an error.
    
    ## What changed
    
    - Added core `TurnItem::McpToolCall` with flattened `server`, `tool`,
    `arguments`, `status`, `result`, and `error` fields.
    - Updated MCP tool call emitters, including MCP resource tools, to emit
    `ItemStarted`/`ItemCompleted` around directly constructed core MCP
    items.
    - Updated app-server v2 conversion to project the core MCP item into
    `ThreadItem::McpToolCall` without deriving status or splitting `Result`
    locally.
    - Ignored live deprecated MCP legacy fanout in app-server v2 to avoid
    duplicate item notifications, while keeping thread history replay on the
    legacy event path.

  • [codex] Refactor app-server dispatch result flow (#20897)
    ## Why
    
    App-server request handling had response sending spread across many
    individual handlers, which made it harder to see which requests return
    payloads, which methods send their own delayed response, and which
    branches emit notifications after a response.
    
    ## What changed
    
    - Centralized normal `ClientResponsePayload` sending in the dispatch
    path.
    - Kept explicit-response methods explicit where they need custom
    ordering or delayed delivery.
    - Removed forward-only handler wrappers and immediate `async { ...
    }.await` bodies where they were not needed.
    - Moved branch-specific post-response notifications into the branches
    that own the response ordering.
    - Replaced unreachable delegated request-family error arms with explicit
    `unreachable!` cases.

  • [codex] Emit image view as core item (#20512)
    ## Why
    
    Image-view results should be represented as a core-produced turn item
    instead of being reconstructed by app-server. At the same time, existing
    rollout/history paths still understand the legacy `ViewImageToolCall`
    event, so this keeps that event as compatibility output generated from
    the new item lifecycle.
    
    ## What changed
    
    - Added `TurnItem::ImageView` to `codex-protocol`.
    - Emitted image-view item start/completion directly from the core
    `view_image` handler.
    - Kept `ViewImageToolCall` as a legacy event and generate it from
    completed `TurnItem::ImageView` items.
    - Kept `thread_history.rs` on the legacy `ViewImageToolCall` replay
    path, with `ImageView` item lifecycle events ignored there.
    - Updated app-server protocol conversion, rollout persistence, and
    affected exhaustive event matches for the new item plus legacy fan-out
    shape.
