  • Add experimental remote thread store config (#18714)
    Add experimental config to use remote thread store rather than local
    thread store implementation in app server
  • Wire the PatchUpdated events through app_server (#18289)
    Wires patch_updated events through app_server. These events are parsed
    and streamed while apply_patch is being written by the model. Also adds 500ms of buffering to the patch_updated events in the diff_consumer.
    
    The eventual goal is to use this to display better progress indicators in
    the codex app.
  • protocol: canonicalize file system permissions (#18274)
    ## Why
    
    `PermissionProfile` needs stable, canonical file-system semantics before
    it can become the primary runtime permissions abstraction. Without a
    canonical form, callers have to keep re-deriving legacy sandbox maps and
    profile comparisons remain lossy or order-dependent.
    
    ## What changed
    
    This adds canonicalization helpers for `FileSystemPermissions` and
    `PermissionProfile`, expands special paths into explicit sandbox
    entries, and updates permission request/conversion paths to consume
    those canonical entries. It also tightens the legacy bridge so root-wide
    write profiles with narrower carveouts are not silently projected as
    full-disk legacy access.
    
    ## Verification

    root_write_with_read_only_child_is_not_full_disk_write -- --nocapture`

  • codex: move unloaded thread writes into store (#18361)
    - Migrates unloaded `thread/name/set` and `thread/memoryModeSet`
    app-server writes behind the generic
    `ThreadStore::update_thread_metadata` API rather than adding one-off
    store methods for setting thread name or memory mode.
    - Implements the local ThreadStore metadata patch path for thread name
    and memory mode, including rollout append, legacy name index updates,
    SessionMeta validation/update, SQLite reconciliation, and re-reading the
    stored thread.
    - Adds focused local thread-store unit coverage plus app-server
    integration coverage for the migrated unloaded write paths.
  • [codex] Use background task auth for additional backend calls (#18260)
    ## Summary
    
    Splits the larger PR4.1 background task auth rollout by moving
    additional backend/control-plane call sites into this downstream PR.
    
    This PR keeps callers on the same design as PR4.1: most code asks
    `AuthManager` for the default ChatGPT backend authorization header, and
    `AuthManager` decides bearer vs background AgentAssertion internally.
    Task-pinned inference auth remains separate because it needs the
    thread's registered task id.

  • [codex] Use background agent task auth for backend calls (#18094)
    ## Summary
    
    Introduces a single background/control-plane agent task for ChatGPT
    backend requests that do not have a thread-scoped task, with
    `AuthManager` owning the default ChatGPT backend authorization decision.
    
    Callers now ask `AuthManager` for the default ChatGPT backend
    authorization header. `AuthManager` decides whether that is bearer or
    background AgentAssertion based on config/internal state, while
    low-level bootstrap paths can explicitly request bearer-only auth.
    
    This PR is stacked on PR4 and focuses on the shared background task auth
    plumbing plus the first tranche of backend/control-plane consumers. The
    remaining callsite wiring is split into PR4.2 to keep review size down.

    - make `BackgroundAgentTaskManager` private to `codex-login`; call sites
    do not instantiate or pass it around
    - teach `AuthManager` the ChatGPT backend base URL and feature-derived
    background auth mode from resolved config
    - expose bearer-only helpers for bootstrap/registration/refresh-style
    paths that must not use AgentAssertion
    - wire `AuthManager` default ChatGPT authorization through app listing,
    connector directory listing, remote plugins, MCP status/listing,
    analytics, and core-skills remote calls
    - preserve bearer fallback when the feature is disabled, the backend
    host is unsupported, or background task registration is not available

  • fix: trust-gate project hooks and exec policies (#14718)
    ## Summary
    - trust-gate project `.codex` layers consistently, including repos that
    have `.codex/hooks.json` or `.codex/execpolicy/*.rules` but no
    `.codex/config.toml`
    - keep disabled project layers in the config stack so nested trusted
    project layers still resolve correctly, while preventing hooks and exec
    policies from loading until the project is trusted
    - update app-server/TUI onboarding copy to make the trust boundary
    explicit and add regressions for loader, hooks, exec-policy, and
    onboarding coverage
    
    ## Security
    Before this change, an untrusted repo could auto-load project hooks or
    exec policies from `.codex/` as long as `config.toml` was absent. This
    makes trust the single gate for project-local config, hooks, and exec
    policies.

  • feat: Add remote plugin fields to plugin API (#17277)
    ## Summary
    Update the plugin API for the new remote plugin model.
    
    The mental model is no longer “keep local plugin state in sync with
    remote.” Instead, local and remote plugins are becoming separate
    sources. Remote catalog entries can be shown directly from the remote
    API before installation; after installation they are still downloaded
    into the local cache for execution, but remote installed state will come
    from the API and be held in memory rather than being read from config.
    
    • ## API changes
    - Remove `forceRemoteSync` from `plugin/list`, `plugin/install`, and
    `plugin/uninstall`.
      - Remove `remoteSyncError` from `plugin/list`.
      - Add remote-capable metadata to `plugin/list` / `plugin/read`:
        - nullable `marketplaces[].path`
        - `source: { type: "remote", downloadUrl }`
        - URL asset fields alongside local path fields:
      `composerIconUrl`, `logoUrl`, `screenshotUrls`
      - Make `plugin/read` and `plugin/install` source-compatible:
        - `marketplacePath?: AbsolutePathBuf | null`
        - `remoteMarketplaceName?: string | null`
        - exactly one source is required at runtime
  • [codex] Add cross-repo plugin sources to marketplace manifests (#18017)
    ## Summary
    - add first-class marketplace support for git-backed plugin sources
    - keep the newer marketplace parsing behavior from `main`, including
    alternate manifest locations and string local sources
    - materialize remote plugin sources during install, detail reads, and
    non-curated cache refresh
    - expose git plugin source metadata through the app-server protocol
    
    ## Details
    This teaches the marketplace parser to accept all of the following:
    - local string sources such as `"source": "./plugins/foo"`
    - local object sources such as
    `{"source":"local","path":"./plugins/foo"}`
    - remote repo-root sources such as
    `{"source":"url","url":"https://github.com/org/repo.git"}`
    - remote subdir sources such as
    `{"source":"git-subdir","url":"owner/repo","path":"plugins/foo","ref":"main","sha":"..."}`
    
    It also preserves the newer tolerant behavior from `main`: invalid or
    unsupported plugin entries are skipped instead of breaking the whole
    marketplace.
    
    ## Validation
    - `cargo test -p codex-core plugins::marketplace::tests`
    - `just fix -p codex-core`
    - `just fmt`
    
    ## Notes
    - A full `cargo test -p codex-core` run still hit unrelated existing
    failures in agent and multi-agent tests during this session; the
    marketplace-focused suite passed after the rebase resolution.
  • refactor: narrow async lock guard lifetimes (#18211)
    Follow-up to https://github.com/openai/codex/pull/18178, where we called
    out enabling the await-holding lint as a follow-up.
    
    The long-term goal is to enable Clippy coverage for async guards held
    across awaits. This PR is intentionally only the first, low-risk cleanup
    pass: it narrows obvious lock guard lifetimes and leaves
    `codex-rs/Cargo.toml` unchanged so the lint is not enabled until the
    remaining cases are fixed or explicitly justified. It intentionally
    leaves the active-turn/turn-state locking pattern alone because those
    checks and mutations need to stay atomic.
    
    ## Common fixes used here
    
    These are the main patterns reviewers should expect in this PR, and they
    are also the patterns to reach for when fixing future `await_holding_*`
    findings:
    
    - **Scope the guard to the synchronous work.** If the code only needs
    data from a locked value, move the lock into a small block, clone or
    compute the needed values, and do the later `.await` after the block.
    - **Use direct one-line mutations when there is no later await.** Cases
    like `map.lock().await.remove(&id)` are acceptable when the guard is
    only needed for that single mutation and the statement ends before any
    async work.
    - **Drain or clone work out of the lock before notifying or awaiting.**
    For example, the JS REPL drains pending exec senders into a local vector
    and the websocket writer clones buffered envelopes before it serializes
    or sends them.
    - **Use a `Semaphore` only when serialization is intentional across
    async work.** The test serialization guards intentionally span awaited
    setup or execution, so using a semaphore communicates "one at a time"
    without holding a mutex guard.
    - **Remove the mutex when there is only one owner.** The PTY stdin
    writer task owns `stdin` directly; the old `Arc<Mutex<_>>` did not
    protect shared access because nothing else had access to the writer.
    - **Do not split locks that protect an atomic invariant.** This PR
    deliberately leaves active-turn/turn-state paths alone because those
    checks and mutations need to stay atomic. Those cases should be fixed
    separately with a design change or documented with `#[expect]`.
    
    ## What changed
    
    - Narrow scoped async mutex guards in app-server, JS REPL, network
    approval, remote-control websocket, and the RMCP test server.
    - Replace test-only async mutex serialization guards with semaphores
    where the guard intentionally lives across async work.
    - Let the PTY pipe writer task own stdin directly instead of wrapping it
    in an async mutex.
    
    ## Verification

    codex-shell-escalation -p codex-utils-pty -p codex-utils-readiness`

    sandbox on six otel approval tests plus
    `suite::user_shell_cmd::user_shell_command_does_not_set_network_sandbox_env_var`,
    which appear to depend on local command approval/default rules and
    `CODEX_SANDBOX_NETWORK_DISABLED=1` in this environment.

  • Add sorting/backwardsCursor to thread/list and new thread/turns/list api (#17305)
    To improve performance of UI loads from the app, add two main
    improvements:
    1. The `thread/list` api now gets a `sortDirection` request field and a
    `backwardsCursor` to the response, which lets you paginate forwards and
    backwards from a window. This lets you fetch the first few items to
    display immediately while you paginate to fill in history, then can
    paginate "backwards" on future loads to catch up with any changes since
    the last UI load without a full reload of the entire data set.
    2. Added a new `thread/turns/list` api which also has sortDirection and
    backwardsCursor for the same behavior as `thread/list`, allowing you the
    same small-fetch for immediate display followed by background fill-in
    and resync catchup.

  • feat(config): support managed deny-read requirements (#17740)
    ## Summary
    - adds managed requirements support for deny-read filesystem entries
    - constrains config layers so managed deny-read requirements cannot be
    widened by user-controlled config
    - surfaces managed deny-read requirements through debug/config plumbing
    
    This PR lets managed requirements inject deny-read filesystem
    constraints into the effective filesystem sandbox policy.
    User-controlled config can still choose the surrounding permission
    profile, but it cannot remove or weaken the managed deny-read entries.
    
    ## Managed deny-read shape
    A managed requirements file can declare exact paths and glob patterns
    under `[permissions.filesystem]`:
    
    ```toml
    # /etc/codex/requirements.toml
    [permissions.filesystem]
    deny_read = [
      "/Users/alice/.gitconfig",
      "/Users/alice/.ssh",
      "./managed-private/**/*.env",
    ]
    ```
    
    Those entries are compiled into the effective filesystem policy as
    `access = none` rules, equivalent in shape to filesystem permission
    entries like:
    
    ```toml
    [permissions.workspace.filesystem]
    "/Users/alice/.gitconfig" = "none"
    "/Users/alice/.ssh" = "none"
    "/absolute/path/to/managed-private/**/*.env" = "none"
    ```
    
    The important difference is that the managed entries come from
    requirements, so lower-precedence user config cannot remove them or make
    those paths readable again.
    
    Relative managed `deny_read` entries are resolved relative to the
    directory containing the managed requirements file. Glob entries keep
    their glob suffix after the non-glob prefix is normalized.
    
    ## Runtime behavior
    - Managed `deny_read` entries are appended to the effective
    `FileSystemSandboxPolicy` after the selected permission profile is
    resolved.
    - Exact paths become `FileSystemPath::Path { access: None }`; glob
    patterns become `FileSystemPath::GlobPattern { access: None }`.
    - When managed deny-read entries are present, `sandbox_mode` is
    constrained to `read-only` or `workspace-write`; `danger-full-access`
    and `external-sandbox` cannot silently bypass the managed read-deny
    policy.
    - On Windows, the managed deny-read policy is enforced for direct file
    tools, but shell subprocess reads are not sandboxed yet, so startup
    emits a warning for that platform.
    - `/debug-config` shows the effective managed requirement as
    `permissions.filesystem.deny_read` with its source.

    2. #18096 - macOS and Linux sandbox enforcement

  • Sync local plugin imports, async remote imports, refresh caches after… (#18246)
    … import
    
    ## Why
    
    `externalAgentConfig/import` used to spawn plugin imports in the
    background and return immediately. That meant local marketplace imports
    could still be in flight when the caller refreshed plugin state, so
    newly imported plugins would not show up right away.
    
    This change makes local marketplace imports complete before the RPC
    returns, while keeping remote marketplace imports asynchronous so we do
    not block on remote fetches.
    
    ## What changed
    
    - split plugin migration details into local and remote marketplace
    imports based on the external config source
    - import local marketplaces synchronously during
    `externalAgentConfig/import`
    - return pending remote plugin imports to the app-server so it can
    finish them in the background
    - clear the plugin and skills caches before responding to plugin
    imports, and again after background remote imports complete, so the next
    `plugin/list` reloads fresh state
    - keep marketplace source parsing encapsulated behind
    `is_local_marketplace_source(...)` instead of re-exporting the internal
    enum
    - add core and app-server coverage for the synchronous local import path
    and the pending remote import path

  • [codex] Revoke ChatGPT tokens on logout (#17825)
    ## Summary
    
    This changes Codex logout so managed ChatGPT auth is revoked against
    AuthAPI before local auth state is removed. CLI logout, TUI `/logout`,
    and the app-server account logout path now use the token-revoking logout
    flow instead of only deleting `auth.json` / credential store state.
    
    ## Root Cause
    
    Logout previously cleared only local auth storage. That removed Codex's
    local credentials but did not ask the backend to invalidate the
    refresh/access token state associated with a managed ChatGPT login.
    
    ## Behavior
    
    For managed ChatGPT auth, logout sends the stored refresh token to
    `https://auth.openai.com/oauth/revoke` with `token_type_hint:
    refresh_token` and the Codex OAuth client id, then deletes all local
    auth stores after revocation succeeds. If only an access token is
    available, it falls back to revoking that access token. API key auth and
    externally supplied `chatgptAuthTokens` are still only cleared locally
    because Codex does not own a refresh token for those modes.
    
    Revocation failures are fail-closed: if Codex cannot load stored auth or
    the backend revoke call fails, logout returns an error and leaves local
    auth in place so the user can retry instead of silently clearing local
    state while backend tokens remain valid.
    
    ## Validation
    ran local version of `codex-cli` with staging overrides/harness for auth
    
    ran `codex login` then `codex logout`:
    
    saw auth.json clear and  backend revocation endpoints were called
    
    ```
    POST /oauth/revoke
    status: 200
    
    revoking access token
    should clear auth session
    clearing auth session due to token revocation
    successfully revoked session and access token
    CANONICAL-API-LINE Response: status='200' method='POST' path='/oauth/revoke

  • Refactor config loading to use filesystem abstraction (#18209)
    Initial pass propagating FileSystem through config loading.
  • fix(app-server): replay token usage after resume and fork (#18023)
    ## Problem
    
    When a user resumed or forked a session, the TUI could render the
    restored thread history immediately, but it did not receive token usage
    until a later model turn emitted a fresh usage event. That left the
    context/status UI blank or stale during the exact window where the user
    expects resumed state to look complete. Core already reconstructed token
    usage from the rollout; the missing behavior was app-server lifecycle
    replay to the client that just attached.
    
    ## Mental model
    
    Token usage has two representations. The rollout is the durable source
    of historical `TokenCount` events, and the core session cache is the
    in-memory snapshot reconstructed from that rollout on resume or fork.
    App-server v2 clients do not read core state directly; they learn about
    usage through `thread/tokenUsage/updated`. The fix keeps those roles
    separate: core exposes the restored `TokenUsageInfo`, and app-server
    sends one targeted notification after a successful `thread/resume` or
    `thread/fork` response when that restored snapshot exists.
    
    This notification is not a new model event. It is a replay of
    already-persisted state for the client that just attached. That
    distinction matters because using the normal core event path here would
    risk duplicating `TokenCount` entries in the rollout and making future
    resumes count historical usage twice.
    
    ## Non-goals
    
    This change does not add a new protocol method or payload shape. It
    reuses the existing v2 `thread/tokenUsage/updated` notification and the
    TUI’s existing handler for that notification.
    
    This change does not alter how token usage is computed, accumulated,
    compacted, or written during turns. It only exposes the token usage that
    resume and fork reconstruction already restored.
    
    This change does not broadcast historical usage replay to every
    subscribed client. The replay is intentionally scoped to the connection
    that requested resume or fork so already-attached clients are not
    surprised by an old usage update while they may be rendering live
    activity.
    
    ## Tradeoffs
    
    Sending the usage notification after the JSON-RPC response preserves a
    clear lifecycle order: the client first receives the thread object, then
    receives restored usage for that thread. The tradeoff is that usage is
    still a notification rather than part of the `thread/resume` or
    `thread/fork` response. That keeps the protocol shape stable and avoids
    duplicating usage fields across response types, but clients must
    continue listening for notifications after receiving the response.
    
    The helper selects the latest non-in-progress turn id for the replayed
    usage notification. This is conservative because restored usage belongs
    to completed persisted accounting, not to newly attached in-flight work.
    The fallback to the last turn preserves a stable wire payload for
    unusual histories, but histories with no meaningful completed turn still
    have a weak attribution story.
    
    ## Architecture
    
    Core already seeds `Session` token state from the last persisted rollout
    `TokenCount` during `InitialHistory::Resumed` and
    `InitialHistory::Forked`. The new core accessor exposes the complete
    `TokenUsageInfo` through `CodexThread` without giving app-server direct
    session mutation authority.
    
    App-server calls that accessor from three lifecycle paths: cold
    `thread/resume`, running-thread resume/rejoin, and `thread/fork`. In
    each path, the server sends the normal response first, then calls a
    shared helper that converts core usage into
    `ThreadTokenUsageUpdatedNotification` and sends it only to the
    requesting connection.
    
    The tests build fake rollouts with a user turn plus a persisted token
    usage event. They then exercise `thread/resume` and `thread/fork`
    without starting another model turn, proving that restored usage arrives
    before any next-turn token event could be produced.
    
    ## Observability
    
    The primary debug path is the app-server JSON-RPC stream. After
    `thread/resume` or `thread/fork`, a client should see the response
    followed by `thread/tokenUsage/updated` when the source rollout includes
    token usage. If the notification is absent, check whether the rollout
    contains an `event_msg` payload of type `token_count`, whether core
    reconstruction seeded `Session::token_usage_info`, and whether the
    connection stayed attached long enough to receive the targeted
    notification.
    
    The notification is sent through the existing
    `OutgoingMessageSender::send_server_notification_to_connections` path,
    so existing app-server tracing around server notifications still
    applies. Because this is a replay, not a model turn event, debugging
    should start at the resume/fork handlers rather than the turn event
    translation in `bespoke_event_handling`.
    
    ## Tests
    
    The focused regression coverage is `cargo test -p codex-app-server
    emits_restored_token_usage`, which covers both resume and fork. The core
    reconstruction guard is `cargo test -p codex-core
    record_initial_history_seeds_token_info_from_rollout`.
    
    Formatting and lint/fix passes were run with `just fmt`, `just fix -p
    codex-core`, and `just fix -p codex-app-server`. Full crate test runs
    surfaced pre-existing unrelated failures in command execution and plugin
    marketplace tests; the new token usage tests passed in focused runs and
    within the app-server suite before the unrelated command execution
    failure.
  • Refactor AGENTS.md discovery into AgentsMdManager (#18035)
    Encapsulate Agents MD processing a bit and drop user_instructions_path
    from config.
  • Auto-upgrade configured marketplaces (#17425)
    ## Summary
    - Add best-effort auto-upgrade for user-configured Git marketplaces
    recorded in `config.toml`.
    - Track the last activated Git revision with `last_revision` so
    unchanged marketplace sources skip clone work.
    - Trigger the upgrade from plugin startup and `plugin/list`, while
    preserving existing fail-open plugin behavior with warning logs rather
    than new user-visible errors.
    
    ## Details
    - Remote configured marketplaces use `git ls-remote` to compare the
    source/ref against the recorded revision.
    - Upgrades clone into a staging directory, validate that
    `.agents/plugins/marketplace.json` exists and that the manifest name
    matches the configured marketplace key, then atomically activate the new
    root.
    - Local `.agents/plugins/marketplace.json` marketplaces remain live
    filesystem state and are not auto-pulled.
    - Existing non-curated plugin cache refresh is kicked after successful
    marketplace root upgrades.
    
    ## Validation
    - `just write-config-schema`
    - `cargo test -p codex-core marketplace_upgrade`
    - `cargo check -p codex-cli -p codex-app-server`
    - `just fix -p codex-core`
    
    Did not run the complete `cargo test` suite because the repo
    instructions require asking before a full core workspace run.

  • Fix MCP startup cancellation through app server (#18078)
    Addresses https://github.com/openai/codex/issues/17143
    
    Problem: TUI interrupts without an active turn stopped cancelling slow
    MCP startup after routing through the app-server APIs.
    
    Solution: Route no-active-turn interrupts through app-server as startup
    cancels, acknowledge them immediately, and emit cancelled MCP startup
    updates.
    
    Testing: I manually confirmed that MCP cancellation didn't work prior to
    this PR and works after the fix was in place.

    - implement local ThreadStore read_thread operation
    - break up the various ThreadStore local method implementations into
    separate files
    - migrate app-server archive/unarchive and core archive fixture to use
    ThreadStore (but not all read operations yet!)
    - use the ThreadStore's read operation as a proxy check for thread
    persistence/existence in the app server code
    - move all other filesystem operations related to archive (path
    validation etc) into the local thread store.
    
    # Tests
    - add dedicated local store archive/unarchive tests
  • app-server: track remote-control seq IDs per stream (#17902)
    ## Summary
    
    - Track outbound remote-control sequence IDs independently for each
    client stream.
    - Retain unacked outbound messages per stream using FIFO buffers.
    - Require stream-scoped acks and update tests for contiguous per-stream
    sequencing.
    
    ## Why
    
    The remote-control peer uses outbound sequence gaps to detect lost
    messages and re-initialize. A single global outbound sequence counter
    can create apparent gaps on an individual stream when another stream
    receives an interleaved message.

  • [codex] Add local thread store listing (#17824)
    Builds on top of #17659 
    
    Move the filesystem + sqlite thread listing-related operations inside of
    a local ThreadStore implementation and call ThreadStore from the places
    that used to perform these filesystem/sqlite operations.
    
    This is the first of a series of PRs that will implement the rest of the
    local ThreadStore.
    
    Testing:
    - added unit tests for the thread store implementation
    - adjusted some unit tests in the realtime + personality packages whose
    callsites changed. Specifically I'm trying to hide ThreadMetadata inside
    of the local implementation and make ThreadMetadata a sqlite
    implementation detail concern rather than a public interface, preferring
    the more generate StoredThread interface instead
    - added a corner case test for the personality migration package that
    wasn't covered by the existing test suite
    - adjust the behavior of searched thread listing to run the existing
    local rollout repair/backfill pass _before_ querying SQLite results, so
    callers using ThreadStore::list_threads do not miss matches after a
    partial metadata warm-up

    follow-up PR.
    - Shares the processor and initialized session data with

  • Moving updated-at timestamps to unique millisecond times (#17489)
    To allow the ability to have guaranteed-unique cursors, we make two
    important updates:
    * Add new updated_at_ms and created_at_ms columns that are in
    millisecond precision
    * Guarantee uniqueness -- if multiple items are inserted at the same
    millisecond, bump the new one by one millisecond until it becomes unique
    
    This lets us use single-number cursors for forwards and backwards paging
    through resultsets and guarantee that the cursor is a fixed point to do
    (timestamp > cursor) and get new items only.
    
    This updated implementation is backwards-compatible since multiple
    appservers can be running and won't handle the previous method well.
