  • Add app-server startup benchmark crate (#24651)
    ## Summary
    - Add a new `app-server-start-bench` crate to measure app-server startup
    performance
    - Wire the benchmark into the workspace and Bazel build so it can be run
    consistently
    - Update lockfiles and repo automation to account for the new package
  • Update rmcp to 1.7.0 (#24763)
    WIll make it easier to uprev when the new draft spec is supported.
    
    Also updates reqwest where needed for compatibility but doesn't update
    it everywhere since this is already a large diff.
    
    The new version of rmcp handles certain kinds of authentication failures
    differently, this patch includes support for identifying the failing scope
    in a WWW-Authenticate header.
  • Allow API-key auth for remote exec-server registration (#24666)
    ## Overview
    Allow remote `codex exec-server` registration to use existing API-key
    auth while restricting where those credentials can be sent.
    
    - Accept `CodexAuth::ApiKey` for the normal `--remote` registration
    path.
    - Restrict API-key remote registration to HTTPS `openai.com` and
    `openai.org` hosts and subdomains, with explicit HTTP loopback support
    for local development.
    - Disable registry registration redirects so credentials cannot be
    forwarded to an unvalidated destination.
    - Retain `--use-agent-identity-auth` as the explicit Agent Identity
    path.
    - Document remote registration using `CODEX_API_KEY`.
    
    ## Big picture
    Callers can now provide an API key directly to `exec-server`
    registration without first establishing ChatGPT login state:
    
    ```sh
    CODEX_API_KEY="$OPENAI_API_KEY" \
    codex exec-server \
      --remote "https://<host>.openai.org/api" \
      --environment-id "$ENVIRONMENT_ID"
    ```

  • Bump SQLx to pick up newer bundled SQLite (#24728)
    ## Why
    
    Codex stores thread, log, goal, and memory state in bundled SQLite
    databases through SQLx. We have a suspected SQLite WAL-reset corruption
    issue under heavy concurrent writer load, especially when multiple
    subagents are active. The existing `sqlx 0.8.6` dependency kept us on an
    older `libsqlite3-sys` / bundled SQLite, so this PR moves the SQLx stack
    far enough forward to pick up the newer bundled SQLite library.
    
    ## What changed
    
    - Bump the workspace `sqlx` dependency to `0.9.0`.
    - Use the SQLx 0.9 feature names explicitly: `runtime-tokio`,
    `tls-rustls`, and `sqlite-bundled`.
    - Update `Cargo.lock` so `sqlx-sqlite` resolves through `libsqlite3-sys
    0.37.0`.
    - Refresh `MODULE.bazel.lock` for the dependency changes.
    - Adapt `codex-state` to SQLx 0.9:
    - build dynamic state queries with `QueryBuilder<Sqlite>` instead of
    passing dynamic `String`s to `sqlx::query`;
    - remove the old `QueryBuilder` lifetime parameter from helper
    signatures;
    - preserve SQLx's new `Migrator` fields when constructing runtime
    migrators.

  • Attach Windows sandbox log to feedback reports (#24623)
    ## Why
    
    Windows sandbox diagnostics are currently hard to recover from
    `/feedback` even though they are often the most useful artifact when
    debugging sandbox behavior. Now that sandbox logging uses daily rolling
    files, feedback can safely include the current day's sandbox log without
    uploading the old ever-growing legacy `sandbox.log`.
    
    ## What changed
    
    - Add a `codex-windows-sandbox` helper that resolves the current daily
    sandbox log from `codex_home`.
    - When feedback is submitted with logs enabled on Windows, app-server
    attaches today's sandbox log if it exists.
    - Upload the attachment under the stable filename `windows-sandbox.log`,
    independent of the dated on-disk filename.
    - Keep existing raw `extra_log_files` behavior unchanged for rollout and
    desktop log attachments.
    
    ## Verification
    
    - `cargo fmt -p codex-app-server -p codex-windows-sandbox`
    - `cargo test -p codex-windows-sandbox
    current_log_file_path_for_codex_home_uses_sandbox_dir`
    - `cargo test -p codex-app-server
    windows_sandbox_log_attachment_uses_current_log`
    - Manual CLI/TUI `/feedback` test confirmed Sentry received
    `windows-sandbox.log`.
  • tui: keep inaccessible apps out of mentions (#24625)
    ## Summary
    
    Fix the TUI `$` app mention paths so App Directory rows that are not
    accessible are not treated as usable apps.
    
    This includes the core preservation fix from #24104, but expands it to
    the other app mention paths:
    
    - preserve app-server `is_accessible` flags when partial
    `app/list/updated` snapshots reach the TUI
    - require apps to be both accessible and enabled when resolving exact
    `$slug` mentions
    - require restored/stale `app://...` bindings to point at accessible,
    enabled apps before emitting structured app mentions
    - remove the now-unused `codex-chatgpt` dependency from `codex-tui`,
    which addresses the `cargo shear` failure seen on #24104
    
    ## Root Cause
    
    The app server already sends merged app snapshots with accessibility
    computed. The TUI handled app-server app list updates as partial app
    loads and re-ran the old accessible-app merge path. That path treated
    every notification row as accessible, so App Directory entries with
    `isAccessible=false` could appear in `$` suggestions.
    
    Regression source: #22914 routed app-list updates through the app server
    while reusing the old TUI partial-load handling. Related precursor:
    #14717 introduced the partial-load path, but #22914 made it user-visible
    for app-server updates.

  • standalone websearch extension (#23823)
    ## Summary
    
    Add the extension-backed standalone `web.run` tool so Codex can call the
    standalone search endpoint through the `codex-api` search client and
    return its encrypted output to Responses.
    
    - gate the new tool behind `standalone_web_search`
    - install the extension in the app-server thread registry and hide
    hosted `web_search` when standalone search is enabled for OpenAI
    providers so the two paths stay mutually exclusive
    - build search context from persisted history using a small tail
    heuristic: previous user message, assistant text between the last two
    user turns capped at about 1k tokens, and current user message
    
    ## Test Plan
    
    - `cargo test -p codex-web-search-extension`
    - `cargo test -p codex-api`
    - `cargo test -p codex-core

  • Add goal extension telemetry parity (#24615)
    ## Why
    
    `core/src/goals.rs` already emits OTEL metrics for goal creation,
    resume, terminal transitions, token counts, and duration. As `/goal`
    moves into `ext/goal`, the extension needs to preserve that telemetry
    contract instead of only emitting app-visible `ThreadGoalUpdated`
    events.
    
    This keeps the existing `codex.goal.*` metric surface intact while goal
    lifecycle ownership shifts toward the extension.
    
    ## What changed
    
    - Added an extension-local `GoalMetrics` helper that records the
    existing `codex.goal.*` counters and histograms through `codex-otel`.
    - Threaded an optional `MetricsClient` through `install_with_backend`,
    `GoalExtension`, `GoalRuntimeHandle`, and `GoalToolExecutor`.
    - Emitted created, resumed, and terminal goal metrics from the extension
    paths that create goals, restore active goals on thread resume, account
    budget limits, complete or block goals, and handle external goal
    mutations.
    - Updated existing goal extension test setup callsites to pass `None`
    for metrics when instrumentation is not under test.

  • fix: drop flake (#24588)
    Dropping already commented out stuff
  • chore: move memory prompt builder into extension (#24558)
    ## Why
    
    The memories extension now owns the read-path developer instructions it
    injects at thread start. Keeping that prompt builder and template in
    `codex-memories-read` left the extension depending on a helper crate for
    extension-specific prompt assembly, and kept async template/truncation
    dependencies in the read crate after the remaining read surface no
    longer needed them.
    
    ## What changed
    
    - Moved `prompts.rs`, its tests, and `templates/memories/read_path.md`
    from `memories/read` into `ext/memories`.
    - Wired `MemoryExtension` to call the local prompt builder and added the
    moved templates to `ext/memories/BUILD.bazel` compile data.
    - Removed the now-unused prompt export and prompt-related dependencies
    from `codex-memories-read`.
    
    ## Testing
    
    - Not run locally.
  • chore: drop orphaned codex memories MCP crate (#24555)
    ## Why
    
    The memory read-tool surface had two implementations: the app-server
    extension path under `ext/memories`, and an unused `codex-memories-mcp`
    workspace crate under `memories/mcp`. The MCP crate no longer has
    reverse dependents, so keeping it around preserves duplicate backend,
    schema, and tool code that is not part of the live app-server memory
    path.
    
    Dropping the orphaned crate makes the remaining memory crate split
    clearer: `memories/read` owns read-path prompt/citation helpers,
    `memories/write` owns the write pipeline, and `ext/memories` owns the
    app-server extension integration.
    
    ## What changed
    
    - Removed the `memories/mcp` crate and its Bazel/Cargo metadata.
    - Removed `memories/mcp` from the Rust workspace and lockfile.
    - Updated `memories/README.md` so it only lists the remaining reusable
    memory crates.
    
    ## Verification
    
    - `cargo metadata --format-version 1 --no-deps` succeeds.
  • Add doctor thread inventory audit (#24305)
    ## Why
    
    Users have been reporting missing sessions in the app. The app server
    thread listing is backed by the SQLite state DB, but the durable source
    of truth for a thread still exists on disk as rollout JSONL. When the
    state DB is incomplete, doctor should be able to show the mismatch
    directly instead of leaving users with a generic state health result.
    
    ## What changed
    
    This adds a `threads` doctor check that compares active and archived
    rollout files under `CODEX_HOME` with rows in the SQLite `threads`
    table. The check reports missing rollout rows, stale DB rows, archive
    flag mismatches, duplicate rollout thread IDs, duplicate DB paths,
    source/provider summaries, and bounded samples of affected rollout
    paths.
    
    It also adds a read-only state audit helper in `codex-rs/state` so
    doctor can inspect thread rows without creating, migrating, or repairing
    the database.
    
    ## Sample output

  • feat(doctor): add environment diagnostics (#24261)
    ## Why
    
    Issue #23031 was hard to diagnose from existing `codex doctor` output
    because support could not see the OS language, resolved Git install, Git
    repo metadata, Windows console mode/code page, or terminal-title inputs
    that affect the TUI startup path. This adds those read-only signals to
    `codex doctor` so Windows, Linux, and macOS reports carry the context
    needed to investigate similar terminal rendering regressions.
    
    Refs #23031
    
    ## What Changed
    
    - Add a `system.environment` check for OS type/version, OS language, and
    locale env vars.
    - Add a `git.environment` check for the selected Git executable, PATH
    Git candidates, version, exec path/build options, repository root,
    branch, `.git` entry, and `core.fsmonitor`.
    - Add Windows console code page and VT-processing mode details to
    terminal diagnostics.
    - Add a `terminal.title` check for configured/default title items and
    resolved project-title source/value.
    - Surface startup warning counts in config diagnostics and teach human
    output to render the new categories.
    
    ## How to Test
    
    1. On Windows, check out this branch and run `cargo run -p codex-cli --
    doctor --summary`.
    2. Confirm the Environment section includes `system`, `git`, `terminal`,
    and `title` rows.
    3. Run `cargo run -p codex-cli -- doctor --json`.
    4. Confirm the JSON contains `system.environment`, `git.environment`,
    and `terminal.title`; on Windows, confirm `terminal.env` details include
    console code pages and `VT processing` for stdout/stderr.
    5. From a non-git directory, run the same `doctor --json` command and
    confirm the Git check reports `repo detected: false` rather than
    warning.
    
    Targeted tests:
    
    - `cargo test -p codex-cli doctor`
    - `cargo test -p codex-cli`
  • package: include zsh fork in Codex package (#23756)
    ## Why
    
    The package layout gives Codex a stable place for runtime helpers that
    should travel with the entrypoint. `shell_zsh_fork` still required users
    to configure `zsh_path` manually, even though we already publish
    prebuilt zsh fork artifacts.
    
    This PR builds on #24129 and uses the shared DotSlash artifact fetcher
    to include the zsh fork in Codex packages when a matching target
    artifact exists. Packaged Codex builds can then discover the bundled
    fork automatically; the user/profile `zsh_path` override is removed so
    the feature uses the package-managed artifact instead of a legacy path
    knob.
    
    ## What Changed
    
    - Added `scripts/codex_package/codex-zsh`, a checked-in DotSlash
    manifest for the current macOS arm64 and Linux zsh fork artifacts.
    - Taught `scripts/build_codex_package.py` to fetch the matching zsh fork
    artifact and install it at `codex-resources/zsh/bin/zsh` when available
    for the selected target.
    - Added package layout validation for the optional bundled zsh resource.
    - Added `InstallContext::bundled_zsh_path()` and
    `InstallContext::bundled_zsh_bin_dir()` for package-layout resource
    discovery.
    - Threaded the packaged zsh path through config loading as the runtime
    `zsh_path` for packaged installs, and removed the config/profile/CLI
    override path.
    - Kept the packaged default zsh override typed as `AbsolutePathBuf`
    until the existing runtime `Config::zsh_path` boundary.
    - Updated app-server zsh-fork integration tests to spawn
    `codex-app-server` from a temporary package layout with
    `codex-resources/zsh/bin/zsh`, matching the new packaged discovery path
    instead of setting `zsh_path` in config.
    - Switched package executable copying from metadata-preserving `copy2()`
    to `copyfile()` plus explicit executable bits, which avoids macOS
    file-flag failures when local smoke tests use system binaries as inputs.
    
    ## Testing
    
    To verify that the `zsh` executable from the Codex package is picked up
    correctly, first I ran:
    
    ```shell
    ./scripts/build_codex_package.py
    ```
    
    which created:
    
    ```
    /private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/
    ```
    
    so then I ran:
    
    ```
    /private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/bin/codex exec --enable shell_zsh_fork 'run `echo $0`'
    ```
    
    which reported the following, as expected:
    
    ```
    /private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/codex-resources/zsh/bin/zsh
    ```

  • chore: add JSON schema policy fixture coverage (#24152)
    ## Why
    
    Before changing the Codex Bridge JSON schema policy, add integration
    coverage around real connector-like MCP tool schemas. The existing unit
    tests cover individual sanitizer behaviors, but they do not make it easy
    to see whether full fixture schemas keep model-visible guidance, prune
    only unreachable definitions, drop unsupported JSON Schema fields, and
    stay within the Responses API schema budget.
    
    ## What Changed
    
    - Added `tools/tests/json_schema_policy_fixtures.rs`, which converts MCP
    tool fixtures through `mcp_tool_to_responses_api_tool` and validates the
    resulting Responses tool parameters.
    - Added connector-style fixtures for Slack, Google Calendar, Google
    Drive, Notion, and Microsoft Outlook Email under
    `tools/tests/fixtures/json_schema_policy/`.
    - Added fixture assertions for preserved guidance, pruned definitions,
    expected field drops after `JsonSchema` conversion, marker count
    baselines, and dangling local `$ref` prevention.
    - Added a real oversized golden Notion `create_page` input schema
    fixture to exercise the compaction path that strips descriptions, drops
    root `$defs`, rewrites local refs, and fits the compacted schema under
    the budget.
  • [codex] Add image re-encoding benchmarks (#23935)
    ## Summary
    - add Divan benchmarks for prompt image re-encoding paths
    - wire the image benchmark smoke test into Rust CI workflows
    
    ## Why
    Image prompt handling includes re-encoding work that benefits from
    repeatable benchmark coverage so changes can be measured in CI and
    locally.
    
    This already helped identify a potential regression from changing compiler flags.
    
    ## Impact
    Developers can run and compare the new image re-encoding benchmarks, and
    CI exercises the benchmark target via the Rust benchmark smoke test.
  • [codex] Use rolling files for Windows sandbox logs (#24117)
    ## Why
    
    Windows sandbox diagnostics currently append to a single `sandbox.log`
    under `CODEX_HOME/.sandbox`. That file never rolls over, which makes it
    hard to safely include sandbox diagnostics in future feedback reports
    without risking unbounded growth.
    
    ## What changed
    
    - Replaced direct append-open sandbox logging with
    `tracing_appender::rolling::RollingFileAppender`.
    - Configured sandbox logs to rotate daily using names like
    `sandbox.YYYY-MM-DD.log`.
    - Added a conservative `MAX_LOG_FILES` cap of 90 retained matching log
    files.
    - Routed the Windows sandbox setup helper through the same rolling
    writer.
    - Added helpers for resolving the current daily sandbox log path so
    future feedback upload work can use the same filename logic.
    - Updated tests and test diagnostics to read the dated daily log file.
    
    This intentionally does not include sandbox logs in `/feedback` yet;
    scrubbing and attachment behavior can happen in a follow-up.
    
    ## Testing
    
    - `cargo fmt -p codex-windows-sandbox`
    - `cargo check -p codex-windows-sandbox`
    - `cargo test -p codex-windows-sandbox`
    - `cargo test -p codex-windows-sandbox logging::tests`
    - `cargo clippy -p codex-windows-sandbox --all-targets -- -D warnings`
  • feat: support local refs and defs in tool input schemas (#23357)
    # Why
    
    Some connector tool input schemas use local JSON Schema references and
    definition tables to avoid duplicating large nested shapes. Codex
    previously lowered these schemas into the supported subset in a way that
    could discard `$ref`-only schema objects and lose the corresponding
    definitions, which made non-strict tool registration less faithful than
    the original connector schema.
    
    This keeps the existing minimal-lowering policy: Codex still does not
    raw-pass through arbitrary JSON Schema, but it now preserves local
    reference structure that fits the Responses-compatible subset and prunes
    definition entries that cannot be reached by following `$ref`s from the
    root schema after sanitization, including refs found transitively inside
    other reachable definitions. The pruning matters because Responses
    parses definition tables even when entries are unused, so keeping dead
    definitions wastes prompt tokens.
    
    # What changed
    
    - Added `$ref`, `$defs`, and legacy `definitions` fields to the tool
    `JsonSchema` representation.
    - Updated `parse_tool_input_schema` lowering so `$ref`-only schema
    objects survive sanitization instead of becoming `{}`.
    - Sanitized definition tables recursively and dropped malformed
    definition tables so non-strict registration degrades gracefully.
    - Added reachability pruning for root definition tables by starting from
    refs outside definition tables, then following refs inside reachable
    definitions.
    - Added JSON Pointer decoding for local definition refs such as
    `#/$defs/Foo~1Bar`.
    
    # Verification
    ran local golden-schema probes against representative connector schemas
    to validate behavior on real generated schemas:
    
    | Golden schema | Before bytes | After bytes | `$defs` before -> after |
    `$ref` before -> after | Result |
    |---|---:|---:|---:|---:|---|
    | `google_calendar/create_space` | 7111 | 4526 | 7 -> 7 | 7 -> 7 | all
    definitions preserved because all are reachable |
    | `figma/apply_file_variable_changes` | 4609 | 999 | 8 -> 5 | 8 -> 5 |
    unused defs pruned after unsupported `oneOf` shapes lower away |
    | `snowflake/list_catalog_integrations` | 1380 | 404 | 3 -> 0 | 0 -> 0 |
    all defs pruned because none are referenced |
    | `dropbox/create_shared_link` | 8894 | 1836 | 14 -> 4 | 9 -> 4 | only
    defs reachable from the root schema after sanitization are retained,

  • [codex] Make thread search case-insensitive (#23921)
    ## Summary
    - make rollout content search prefilter rollout files case-insensitively
    - keep the no-ripgrep fallback scan and visible snippet matcher aligned
    with that behavior
    - cover a lowercase `thread/search` query matching mixed-case
    conversation content
    
    ## Why
    The rollout-backed `thread/search` path used exact string matching in
    both its `rg` prefilter and semantic snippet generation. A content
    result could be missed solely because the query casing did not match the
    stored conversation text.
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-app-server thread_search_returns_content_matches`
    - `cargo test -p codex-rollout`
    - `just bazel-lock-update`
    - `just bazel-lock-check`
    - `cargo build -p codex-cli`
    - launched a local Electron dev instance with the rebuilt CLI binary
  • [codex] Add rollout-backed thread content search (#23519)
    ## Summary
    - add experimental `thread/search` for local rollout-backed thread
    search using `rg` over JSONL rollouts
    - return search-specific result rows with optional previews instead of
    storing preview data on `StoredThread` or ordinary `Thread` responses
    - keep `thread/list` separate from full-content search and document the
    new app-server surface
    
    ## Testing
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-app-server
    thread_search_returns_content_and_title_matches -- --nocapture`
  • Use named MITM permissions config (#18240)
    ## Stack
    1. Parent PR: #18868 adds MITM hook config and model only.
    2. Parent PR: #20659 wires hook enforcement into the proxy request path.
    3. This PR changes the user facing PermissionProfile TOML shape.
    
    ## Why
    1. The broader goal is to make MITM clamping usable from the same
    permission profile that already controls network behavior.
    2. This PR is the config UX layer for the stack. It moves MITM policy
    into `[permissions.<profile>.network.mitm]` instead of exposing the flat
    runtime shape to users.
    3. The named hook and action tables belong here because users need
    reusable policy blocks that are easy to review, while the proxy runtime
    only needs a flat hook list.
    4. This PR validates action refs during config parsing so mistakes in
    the user facing policy fail before a proxy session starts.
    5. Keeping the lowering here lets the proxy keep its simpler runtime
    model and lets PermissionProfile remain the single source of network
    permission policy.
    
    ## Summary
    1. Keep MITM policy inside `[permissions.<profile>.network.mitm]` so the
    selected PermissionProfile owns network proxy policy.
    2. Use named MITM hooks under
    `[permissions.<profile>.network.mitm.hooks.<name>]`.
    3. Put host, methods, path prefixes, query, headers, body, and action
    refs on the hook table.
    4. Define reusable action blocks under
    `[permissions.<profile>.network.mitm.actions.<name>]`.
    5. Represent action blocks with `NetworkMitmActionToml`, then lower them
    into the proxy runtime action config.
    6. Reject unknown refs, empty refs, and empty action blocks during
    config parsing.
    7. Keep the runtime hook model unchanged by lowering config into the
    existing proxy hook list.
    8. Preserve the #20659 activation fix for nested MITM policy.
    
    ## Example
    ```toml
    [permissions.workspace.network.mitm]
    enabled = true
    
    [permissions.workspace.network.mitm.hooks.github_write]
    host = "api.github.com"
    methods = ["POST", "PUT"]
    path_prefixes = ["/repos/openai/"]
    action = ["strip_auth"]
    
    [permissions.workspace.network.mitm.actions.strip_auth]
    strip_request_headers = ["authorization"]
    ```
    
    ## Validation
    1. Regenerated the config schema.
    2. Ran the core MITM config parsing and validation tests.
    3. Ran the core PermissionProfile MITM proxy activation tests.
    4. Ran the core config schema fixture test.
    5. Ran the network proxy MITM policy tests.
    6. Ran the scoped Clippy fixer for the network proxy crate.
    7. Ran the scoped Clippy fixer for the core crate.

  • Remove Windows sandbox resource stamping (#23764)
    ## Why
    
    The `codex-windows-sandbox` crate was embedding Windows resource
    metadata through a package-level `build.rs`. Because that package also
    exposes the `codex_windows_sandbox` library, downstream binaries that
    link the library could inherit `FileDescription` / `ProductName` values
    of `codex-windows-sandbox`.
    
    That made ordinary Codex binaries, including the long-lived `codex.exe`
    app-server sidecar, appear as `codex-windows-sandbox` in Windows UI
    surfaces such as Task Manager / file properties.
    
    We do not rely on this metadata enough to justify a larger bin-only
    resource split, so this removes the resource stamping entirely.
    
    ## What changed
    
    - Removed the `windows-sandbox-rs` build script that invoked `winres`.
    - Removed the setup manifest that was only consumed by that build
    script.
    - Removed the `winres` build dependency and corresponding `Cargo.lock` /
    `MODULE.bazel.lock` entries.
    - Removed the now-unused Bazel build-script data.
    
    ## Verification
    
    - `cargo build -p codex-windows-sandbox --bins`
    - `cargo build -p codex-cli --bin codex`
    - `bazel mod deps --lockfile_mode=update` via Bazelisk, with local
    remote-cache-disabling flags because `bazel` is not installed on PATH
    here
    - `bazel mod deps --lockfile_mode=error` via Bazelisk, with the same
    local flags
    - Verified rebuilt `codex.exe`, `codex-command-runner.exe`, and
    `codex-windows-sandbox-setup.exe` now have blank `FileDescription` /
    `ProductName` fields.
    - `cargo test -p codex-windows-sandbox` still fails on two legacy
    Windows sandbox tests with `CreateRestrictedToken failed: 87` and the
    follow-on poisoned test lock; 85 passed, 2 ignored.
  • fix(config): resolve cloud requirements deny-read globs (#23729)
    ## Why
    
    Cloud-managed `requirements.toml` contents were deserialized without an
    `AbsolutePathBuf` base directory. Relative managed
    `permissions.filesystem.deny_read` glob entries therefore failed while
    the equivalent local system requirements path succeeded under its
    `AbsolutePathBufGuard`. This follows the `codex_home` base path
    convention clarified in https://github.com/openai/codex/pull/15707.
    
    ## What changed
    
    - Resolve cloud requirements TOML under an `AbsolutePathBufGuard` rooted
    at `codex_home`.
    - Reuse the same base for cloud requirements loaded from the signed
    cache.
    - Add a regression test for a relative cloud-managed `deny_read` glob.
    
    ## Validation
    
    - `just fmt`
    - `cargo test -p codex-cloud-requirements`
    - `cargo clippy -p codex-cloud-requirements --all-targets --no-deps`
    - `just bazel-lock-update`
    - `just bazel-lock-check`
    - `git diff --check`
  • feat: add turn_id and truncation_policy to extension tool calls (#23666)
    ## Why
    
    Extension-owned tools currently receive a stripped `ToolCall` with only
    `call_id`, `tool_name`, and `payload`.
    That makes extension work that needs turn-local execution context
    awkward, especially web-search extension work that needs the active
    `truncation_policy` at tool invocation time.
    
    Reconstructing that value from config or `ExtensionData` would be
    indirect and could drift from the actual turn context, so the cleaner
    fix is to pass the needed turn metadata directly on the extension-facing
    invocation type.
    
    ## What changed
    
    - added `turn_id` and `truncation_policy` to `codex_tools::ToolCall`
    - populated those fields when core adapts `ToolInvocation` into an
    extension tool call
    - added a focused adapter test that verifies extension executors receive
    the forwarded turn metadata
    - updated the memories extension tests to construct the richer
    `ToolCall`
    - added the `codex-utils-output-truncation` dependency to `codex-tools`
    and refreshed lockfiles
    
    ## Testing
    
    - `cargo test -p codex-tools`
    - `cargo test -p codex-memories-extension`
    - `cargo test -p codex-core passes_turn_fields_to_extension_call`
    - `just bazel-lock-update`
    - `just bazel-lock-check`
  • runtime: use install context for bundled bwrap (#23634)
    ## Summary
    
    The Linux sandbox should find bundled `bwrap` through the same
    package-layout abstraction as the rest of the runtime, instead of
    maintaining a separate standalone-specific lookup path.
    
    This adds an `InstallContext` helper for bundled resources and updates
    `codex-linux-sandbox` to ask the current install context for
    `codex-resources/bwrap` before falling back to the old
    executable-relative probes. The tests cover npm-style, standalone, and
    canonical package layouts so `bwrap` lookup follows the package
    structure introduced earlier in the stack.
    
    ## Test plan
    
    - `cargo test -p codex-install-context`
    - `cargo test -p codex-linux-sandbox --lib`
    - `just fix -p codex-install-context -p codex-linux-sandbox`
    - `just bazel-lock-check`

  • feat: wire goal extension tools to the dedicated goal store (#23685)
    ## Why
    
    `ext/goal` already had the tool specs and contributor wiring for
    `/goal`, but the installed tools still depended on a placeholder backend
    that always errored. That meant the extension could not actually own
    goal persistence even though the dedicated `thread_goals` store already
    exists.
    
    This change wires the extension tools directly to the dedicated goal
    store so the extension can create, read, and complete goals against real
    state instead of falling back to host-side placeholders.
    
    ## What changed
    
    - make `install_with_backend(...)` require
    `Arc<codex_state::StateRuntime>` so goal storage is always available
    when the extension is installed
    - remove the unused no-backend/public backend abstraction from
    `ext/goal` and have the tool executors talk directly to `StateRuntime`
    - map `thread_goals` rows into the existing protocol response shape for
    `get_goal`, `create_goal`, and `update_goal`
    - preserve current thread-list behavior by filling an empty thread
    preview from the goal objective when a goal is created through the
    extension path
    - add integration coverage for the installed tool surface, including
    successful goal creation and duplicate-create rejection
    
    ## Testing
    
    - `cargo test -p codex-goal-extension`
  • runtime: detect Codex package layout (#23596)
    ## Why
    
    The package-builder stack now creates a canonical Codex package
    directory where the entrypoint lives under `bin/`, bundled helper
    resources live under `codex-resources/`, and bundled PATH-style tools
    live under `codex-path/`. That layout is not specific to the standalone
    installer: npm, brew, install scripts, and manually unpacked artifacts
    should all be able to use the same package shape.
    
    The Rust runtime still only knew about the legacy standalone release
    layout, where resources sit next to the executable. A packaged binary
    therefore would not identify its package root or prefer the bundled `rg`
    from `codex-path/`.
    
    ## What changed
    
    - Adds `CodexPackageLayout` to `codex-install-context` and detects it
    from an executable path shaped like `<package>/bin/<entrypoint>` when
    `<package>/codex-package.json` is present.
    - Splits `InstallContext` into an install `method` plus an optional
    package layout so the layout is shared across npm, bun, brew,
    standalone, and other launch contexts.
    - Stores package-layout paths as `AbsolutePathBuf` values.
    - Keeps `codex-resources/` and `codex-path/` optional so Codex can still
    run with degraded behavior if sidecar directories are missing.
    - Updates `InstallContext::rg_command()` to prefer bundled
    `codex-path/rg` or `rg.exe`, then fall back to the legacy standalone
    resources location, then system `rg`.
    - Updates `codex doctor` reporting so package installs show package,
    bin, resources, and path directories, and so bundled search detection
    recognizes `codex-path/` for any install method.
    
    ## Test plan
    
    - `cargo test -p codex-install-context`
    - `cargo test -p codex-cli`
    - `cargo test -p codex-tui
    update_action::tests::maps_install_context_to_update_action`
    - `just bazel-lock-check`
  • CI: Customize v8 building (#22086)
    ## Summary
    
    Move the rusty_v8 artifact production into hermetic Bazel path and bump
    the `v8` crate to `147.4.0`
    
    The new flow builds V8 release artifacts from source for Darwin and
    Linux targets, publishes both the current release-compatible artifacts
    and sandbox-enabled variants, and keeps Cargo consumers on prebuilt
    binaries by continuing to feed the `v8` crate the archive and generated
    binding files it already expects.
    
    ## Why
    
    We need control over V8 build-time features without giving up prebuilt
    artifacts for downstream Cargo builds.
    
    Upstream `rusty_v8` already supports source-only features such as
    `v8_enable_sandbox`, but its normal prebuilt release assets do not cover
    every feature combination we need. Building the artifacts ourselves lets
    us enable settings such as the V8 sandbox and pointer compression at
    artifact build time, then publish those outputs so ordinary Cargo builds
    can still consume prebuilts instead of compiling V8 locally.
    
    This keeps the fast consumer experience of prebuilt `rusty_v8` archives
    while giving us a reproducible path to ship featureful variants that
    upstream does not currently publish for us.
    
    ## Implementation Notes
    
    The Bazel graph in this PR is not copied wholesale from `rusty_v8`;
    `rusty_v8`'s normal source build is still GN/Ninja-based.
    
    Instead, this change starts from upstream V8's Bazel rules and adapts
    them to Codex's hermetic toolchains and dependency layout. Where we
    intentionally follow `rusty_v8`, we mirror its existing artifact
    contract:
    
    - the same `v8` crate version and generated binding expectations
    - the same sandbox feature relationship, where sandboxing requires
    pointer compression
    - the same custom libc++ model expected by Cargo's default
    `use_custom_libcxx` feature
    - the same release-style archive plus `src_binding` outputs consumed by
    the `v8` crate
    
    To preserve that contract, the Bazel release path pins the libc++,
    libc++abi, and llvm-libc revisions used by `rusty_v8 v147.4.0`, builds
    release artifacts with `--config=rusty-v8-upstream-libcxx`, and folds
    the matching runtime objects into the final static archive.
    
    ## Windows
    
    Windows is annoyingly handled differently.
    
    Codex's current hermetic Bazel Windows C++ platform is `windows-gnullvm`
    / `x86_64-w64-windows-gnu`, while upstream `rusty_v8` publishes Windows
    prebuilts for `*-pc-windows-msvc`. Those are different ABIs, so the
    Bazel graph cannot truthfully reproduce the upstream MSVC artifacts
    until we add a real MSVC-targeting C++ toolchain.
    
    For now:
    
    - Windows MSVC consumers continue to use upstream `rusty_v8` release
    archives.
    - Windows GNU targets are built in-tree so they link against a matching
    GNU ABI.
    - The canary workflow separately exercises upstream `rusty_v8` source
    builds for MSVC sandbox artifacts, but MSVC is not yet part of the
    Bazel-produced release matrix.
    
    ## Validation
    This PR is technically self validating through CI. I have already
    published it as a release tag so the artifacts from this branch are
    published to
    https://github.com/openai/codex/releases/tag/rusty-v8-v147.4.0 CI for
    this PR should therefore consume our own release targets. I have also
    locally tested for linux and darwin.

  • fix(plugins): keep version upgrades additive (#23356)
    ## Why
    
    Windows can reject plugin cache upgrades when a running MCP server still
    has its working directory inside the currently active plugin version.
    The existing cache refresh path replaces
    `plugins/cache/<marketplace>/<plugin>` as a whole, so a live handle
    under the old version can make an otherwise ordinary version bump fail.
    
    This PR keeps the existing plugin-selection model intact while making
    version bumps less disruptive.
    
    ## What changed
    
    - When installing a new version beside an existing plugin cache root,
    move only the staged version directory into place instead of replacing
    the whole plugin root.
    - Best-effort prune older sibling version directories after the new
    version is activated.
    - Preserve the existing whole-root replacement path for first installs
    and same-version refreshes.
    - Add regression coverage for upgrading from `1.0.0` to `2.0.0` without
    replacing the plugin root.
    
    ## Verification
    
    - `cargo test -p codex-core-plugins install_with_new_version`
    - `cargo fmt --package codex-core-plugins --check`
  • 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.
  • chore: goal ext skeleton (#23288)
    Skeleton of `/goal` in extension
    Lot's of follow-ups coming
  • exec-server: support auth-backed remote executor registration (#22769)
    This updates remote `exec-server` registration to use normal Codex auth
    instead of a registry-issued credential. The registry request is built
    from the existing auth-provider path, which preserves the biscuit-only
    registry contract introduced in
    [openai/openai#924101](https://github.com/openai/openai/pull/924101)
    while removing the old remote registry bearer env var and its direct
    transport assumptions.
    
    The default remote flow uses persisted ChatGPT auth from the normal
    Codex config/storage path. This PR also includes the containerized Agent
    Identity path needed by
    [openai/openai#924260](https://github.com/openai/openai/pull/924260):
    remote `exec-server` accepts `--allow-agent-identity-auth`, permits
    Agent Identity auth loaded from `CODEX_ACCESS_TOKEN` only when that flag
    is present, and reuses the existing Agent task registration plus derived
    `AgentAssertion` header generation. API-key auth remains unsupported,
    and Agent Identity stays opt-in.
    
    Validation performed beyond normal presubmit coverage:
    - `cargo fmt --all --check`
    - `cargo check -p codex-cli`
    - `cargo test -p codex-exec-server`
    - `cargo test -p codex-cli exec_server_agent_identity_auth_flag_`
    - `cargo test -p codex-cli remote_exec_server_auth_mode_`
    
    I also attempted `cargo test -p codex-cli`. The new CLI tests passed
    inside that run, but the suite ended on an unrelated local
    marketplace-state failure in
    `plugin_list_excludes_unconfigured_repo_local_marketplaces`.
  • Move memory prompt injection to app-server extension (#22841)
    ## Why
    
    Memory prompt injection should be owned by the extension path that
    app-server composes at runtime, not by an inlined special case inside
    `codex-core`. This keeps `codex-core` focused on session orchestration
    while allowing the memories extension to own its app-server prompt
    behavior.
    
    ## What Changed
    
    - Registers `codex-memories-extension` in the app-server extension
    registry.
    - Moves the memory developer-instruction injection out of
    `core/src/session/mod.rs` and into the memories extension prompt
    contributor.
    - Adds config-change handling so the extension keeps its per-thread
    memory settings in sync after startup.
    - Leaves memories read/retrieval tools unregistered for now so this PR
    only changes prompt injection.
    - Removes the stale `cargo-shear` ignore now that app-server depends on
    the extension crate.
    
    ## Validation
    
    Not run locally; validation is left to CI.
  • permissions: support workspace roots in profiles (#22610)
    ## Why
    
    This is the configuration/model half of the alternative permissions
    migration we discussed as a comparison point for
    [#22401](https://github.com/openai/codex/pull/22401) and
    [#22402](https://github.com/openai/codex/pull/22402).
    
    The old `workspace-write` model mixes three concerns that we want to
    keep separate:
    - reusable profile rules that should stay immutable once selected
    - user/runtime workspace roots from `cwd`, `--add-dir`, and legacy
    workspace-write config
    - internal Codex writable roots such as memories, which should not be
    shown as user workspace roots
    
    This PR gives permission profiles first-class `workspace_roots` so users
    can opt multiple repositories into the same `:workspace_roots` rules
    without using broad absolute-path write grants. It also starts
    separating the raw selected profile from the effective runtime profile
    by making `Permissions` expose explicit accessors instead of public
    mutable fields.
    
    A representative `config.toml` looks like this:
    
    ```toml
    default_permissions = "dev"
    
    [permissions.dev.workspace_roots]
    "~/code/openai" = true
    "~/code/developers-website" = true
    
    [permissions.dev.filesystem.":workspace_roots"]
    "." = "write"
    ".codex" = "read"
    ".git" = "read"
    ".vscode" = "read"
    ```
    
    If Codex starts in `~/code/codex` with that profile selected, the
    effective workspace-root set becomes:
    - `~/code/codex` from the runtime `cwd`
    - `~/code/openai` from the profile
    - `~/code/developers-website` from the profile
    
    The `:workspace_roots` rules are materialized across each root, so
    `.git`, `.codex`, and `.vscode` stay scoped the same way everywhere.
    Runtime additions such as `--add-dir` can still layer on later stack
    entries without mutating the selected profile.
    
    ## Stack Shape
    
    This PR intentionally stops before the profile-identity cleanup in
    [#22683](https://github.com/openai/codex/pull/22683) so the base review
    stays focused on config loading, workspace-root materialization, and
    compatibility with legacy `workspace-write`.
    
    The representation in this PR is therefore transitional: `Permissions`
    carries enough state to distinguish the raw constrained profile from the
    effective runtime profile, and there are still call sites that must keep
    the active profile identity and constrained profile value in sync. The
    follow-up PR replaces that with a single resolved profile state
    (`ResolvedPermissionProfile` / `PermissionProfileState`) that keeps the
    profile id, immutable `PermissionProfile`, and profile-declared
    workspace roots together. That follow-up removes APIs such as
    `set_constrained_permission_profile_with_active_profile()` where
    separate arguments could drift out of sync.
    
    Downstream PRs then build on this base to switch app-server turn updates
    to profile ids plus runtime workspace roots and to finish the
    user-visible summary behavior. Reviewers should judge this PR as the
    workspace-roots foundation, not as the final in-memory shape of selected
    permission profiles.
    
    ## Review Guide
    
    Suggested review order:
    
    1. Start with `codex-rs/core/src/config/mod.rs`.
    This is the main shape change in the base slice. `Permissions` now
    stores a private raw `Constrained<PermissionProfile>` plus runtime
    `workspace_roots`. Callers use `permission_profile()` when they need the
    raw constrained value and `effective_permission_profile()` when they
    need a materialized runtime profile. As noted above,
    [#22683](https://github.com/openai/codex/pull/22683) replaces this
    transitional shape with a resolved profile state that keeps identity and
    profile data together.
    
    2. Review `codex-rs/config/src/permissions_toml.rs` and
    `codex-rs/core/src/config/permissions.rs`.
    These add `[permissions.<id>.workspace_roots]`, resolve enabled entries
    relative to the policy cwd, and keep `:workspace_roots` deny-read glob
    patterns symbolic until the actual roots are known.
    
    3. Review `codex-rs/protocol/src/permissions.rs` and
    `codex-rs/protocol/src/models.rs`.
    These add the policy/profile materialization helpers that expand exact
    `:workspace_roots` entries and scoped deny-read globs over every
    workspace root. This is also where `ActivePermissionProfileModification`
    is removed from the core model.
    
    4. Review the legacy bridge in
    `Config::load_from_base_config_with_overrides` and
    `Config::set_legacy_sandbox_policy`.
    This is where legacy `workspace-write` roots become runtime workspace
    roots, while Codex internal writable roots stay internal and do not
    appear as user-facing workspace roots.
    
    5. Then skim downstream call sites.
    The interesting pattern is raw-vs-effective access: state/proxy/bwrap
    paths keep the raw constrained profile, while execution, summaries, and
    user-visible status use the effective profile and workspace-root list.
    
    ## What Changed
    
    - added `[permissions.<id>.workspace_roots]` to the config model and
    schema
    - added runtime `workspace_roots` state to `Config`/`Permissions` and
    `ConfigOverrides`
    - made `Permissions` profile fields private and replaced direct mutation
    with accessors/setters
    - added `PermissionProfile` and `FileSystemSandboxPolicy` helpers for
    materializing `:workspace_roots` exact paths and deny-read globs across
    all roots
    - moved legacy additional writable roots into runtime workspace-root
    state instead of active profile modifications
    - removed `ActivePermissionProfileModification` and its app-server
    protocol/schema export
    - updated sandbox/status summary paths so internal writable roots are
    not reported as user workspace roots
    
    ## Verification Strategy
    
    The targeted tests cover the behavior at the layers where regressions
    are most likely:
    - `codex-rs/core/src/config/config_tests.rs` verifies config loading,
    legacy workspace-root seeding, effective profile materialization, and
    memory-root handling.
    - `codex-rs/core/src/config/permissions_tests.rs` verifies profile
    `workspace_roots` parsing and `:workspace_roots` scoped/glob
    compilation.
    - `codex-rs/protocol/src/permissions.rs` unit tests verify exact and
    glob materialization over multiple workspace roots.
    - `codex-rs/tui/src/status/tests.rs` and
    `codex-rs/utils/sandbox-summary/src/sandbox_summary.rs` verify the
    user-facing summaries show effective workspace roots and hide internal
    writes.
    
    I also ran `cargo check --tests` locally after the latest stack refresh
    to catch cross-crate API breakage from the private-field/accessor
    changes.

  • Trim TUI legacy core helper usage (#22695)
    ## Why
    
    The TUI still had a few low-risk dependencies flowing through the
    transitional `legacy_core` namespace after the app-server migration.
    These helpers either already have clearer non-core owners or are
    presentation logic that does not belong in `codex-core`, so moving them
    out reduces the compatibility surface without changing product behavior.
    
    ## What changed
    
    This is a low-risk change, almost completely mechanical in nature.
    
    - Route TUI Codex-home lookup through `codex-utils-home-dir`, use
    `Config::log_dir` directly, and call
    `codex-sandboxing::system_bwrap_warning` without going through
    `legacy_core`.
    - Move shared `codex resume` hint formatting from `codex-core` into
    `codex-utils-cli`.
    - Update CLI and TUI call sites to use the shared CLI utility, and keep
    the resume-command behavior covered by tests in its new home.
    
    ## Verification
    
    - `cargo test -p codex-utils-cli`
    - `cargo test -p codex-utils-cli resume_command`
  • [codex] add plugin marketplace CLI commands (#21396)
    ## Why
    
    Plugin CLI installs should behave more like `apt-get install`:
    configured marketplaces are the only install sources, the local
    marketplace snapshot is the package index used at install time, and
    `plugins/cache` is only a cache of already-downloaded plugin bytes.
    
    That distinction matters once marketplaces and plugins have auth or
    availability state. A repo-local marketplace manifest or leftover cached
    plugin artifact should not silently become an install source unless the
    marketplace was explicitly configured and its readable snapshot still
    authorizes the plugin.
    
    ## What Changed
    
    - add CLI commands to list configured marketplaces and add, list, or
    remove marketplace plugins
    - accept stable `plugin@marketplace` ids for add/remove while preserving
    the explicit `--marketplace` form
    - restrict `codex plugin add` and `codex plugin list` to configured
    marketplaces instead of also discovering current-working-directory
    marketplace roots
    - fail `codex plugin add` and `codex plugin list` when a configured
    marketplace snapshot is missing or malformed instead of treating it as
    an empty source or a generic plugin miss
    - preserve marketplace snapshot semantics: a configured local/Git
    marketplace snapshot can authorize installs without consulting the
    original upstream source
    - allow `plugins/cache` reuse only after configured marketplace
    resolution succeeds
    - keep removal resilient after marketplace deletion or drift and ignore
    malformed marketplace config entries in listing

    ## Public Semantics
    
    - `codex plugin add <plugin>@<marketplace>` succeeds only when
    `<marketplace>` is configured and its local marketplace snapshot
    contains `<plugin>`
    - repo-local marketplaces are not install sources until the user runs
    `codex plugin marketplace add ...`
    - configured marketplace snapshots must be readable; missing or
    malformed snapshots fail the CLI operation rather than silently falling
    through to cache or empty results
    - cached plugin artifacts can satisfy reinstall only when the configured
    marketplace snapshot still authorizes that plugin
    - cached plugin artifacts alone never make a plugin installable
    
    ## Tests
    
    - `cargo test -p codex-cli --test plugin_cli`
    - `cargo clippy -p codex-cli --tests -- -D warnings`
    - `cargo test -p codex-cli`
    - `git diff --check`
    - `just bazel-lock-update`
    - `just bazel-lock-check`
  • feat: make ToolExecutor an async trait (#22560)
    ## Why
    
    `codex_tools::ToolExecutor` keeps a tool spec attached to its runtime
    handler, but extension tools still carried a parallel
    `ExtensionToolFuture` / `ExtensionToolExecutor` shape. That made
    extension-owned tools look different from host tools even though
    routing, registration, and execution need the same abstraction.
    
    This PR makes the shared executor contract directly async and lets
    extension tools implement it too, so host tools and extension tools can
    move through the same registration path.
    
    ## What changed
    
    - Changed `ToolExecutor::handle` to an `async fn` using `async-trait`,
    and updated built-in tool handlers to implement the async trait
    directly.
    - Replaced the bespoke `ExtensionToolFuture` contract with a marker
    `ExtensionToolExecutor` over `ToolExecutor<ToolCall, Output =
    JsonToolOutput>`, re-exporting `ToolExecutor` from
    `codex-extension-api`.
    - Updated the memories extension tools to implement the shared executor
    trait.
    - Split tool-router construction into collected executors plus hosted
    model specs, keeping hosted tools like web search and image generation
    separate from executable handlers.
    - Updated spec/router tests and extension-tool stubs for the new
    executor shape.
    
    ## Verification
    
    - Not run locally.
  • Simplify TUI startup test coverage (#22573)
    ## Why
    
    The TUI startup test surface had drifted into expensive, brittle
    coverage:
    
    - `tui/tests/suite/no_panic_on_startup.rs` was already ignored as flaky
    while still spawning a PTY to exercise malformed exec-policy rules.
    - `tui/tests/suite/model_availability_nux.rs` used a seeded session,
    cursor-query spoofing, and repeated interrupts to verify a narrow
    resume-path invariant.
    - `app/tests.rs` had started accumulating unrelated startup and summary
    coverage in one flat module even after the surrounding app code was
    split into feature modules.
    
    This keeps those behaviors covered while making the tests cheaper to
    understand and less likely to rot. It also preserves the malformed-rules
    regression from #8803 without requiring a terminal orchestration test.
    
    ## What changed
    
    - Replaced the malformed `rules` startup PTY case with a direct
    exec-policy loader regression:
    
    [`rules_path_file_returns_read_dir_error`](https://github.com/openai/codex/blob/21b6b5622f18b8cac0ea41fd083b3106778d9ffc/codex-rs/core/src/exec_policy_tests.rs#L264-L284)
    - Made the existing fresh-session-only startup tooltip behavior explicit
    with
    
    [`should_prepare_startup_tooltip_override`](https://github.com/openai/codex/blob/21b6b5622f18b8cac0ea41fd083b3106778d9ffc/codex-rs/tui/src/app/thread_routing.rs#L1272-L1279),
    then added focused coverage for the resume/fork gate and the persisted
    NUX counter.
    - Split startup and session-summary coverage out of
    `tui/src/app/tests.rs` into dedicated modules so the test layout better
    mirrors the current app architecture.
    - Converted one single-message goal validation snapshot into semantic
    assertions where layout was not the behavior under test.
    - Removed the two PTY-heavy suite files that the narrower tests now
    supersede.
    
    ## Verification
    
    - `cargo test -p codex-core rules_path_file_returns_read_dir_error`
    - `cargo test -p codex-tui startup_`
    - `cargo test -p codex-tui session_summary_`
    - `cargo test -p codex-tui
    goal_slash_command_rejects_oversized_objective`
  • feat(cli): add codex doctor diagnostics (#22336)
    ## Why
    
    Users and support need a single command that captures the local Codex
    runtime, configuration, auth, terminal, network, and state shape without
    asking the user to know which diagnostic depth to choose first. `codex
    doctor` now runs the useful checks by default and makes the detailed
    human output the default because the command is usually run when someone
    already needs context.
    
    The command also targets concrete support failure modes we have seen
    while iterating on the design:
    
    - update-target mismatches like #21956, where the installed package
    manager target can differ from the running executable
    - terminal and multiplexer issues that depend on `TERM`, tmux/zellij
    state, color handling, and TTY metadata
    - provider-specific HTTP/WebSocket connectivity, including ChatGPT
    WebSocket handshakes and API-key/provider endpoint reachability
    - local state/log SQLite integrity problems and large rollout
    directories
    - feedback reports that need an attached, redacted diagnostic snapshot
    without asking the user to run a second command
    
    ## What Changed
    
    - Adds `codex doctor` as a grouped CLI diagnostic report with default
    detailed output and `--summary` for the compact view.
    - Adds stable report sections for Environment, Configuration, Updates,
    Connectivity, and Background Server, plus a top Notes block that
    promotes anomalies such as available updates, large rollout directories,
    optional MCP issues, and mixed auth signals.
    - Adds runtime provenance, install consistency, bundled/system search
    readiness, terminal/multiplexer metadata, `config.toml` parse status,
    auth mode details, sandbox details, feature flag summaries, update
    cache/latest-version state, app-server daemon state, SQLite integrity
    checks, rollout statistics, and provider-aware network diagnostics.
    - Adds ChatGPT WebSocket diagnostics that report the negotiated HTTP
    upgrade as `HTTP 101 Switching Protocols` and include timeout, DNS,
    auth, and provider context in detailed output.
    - Makes reachability provider-aware: API-key OpenAI setups check the API
    endpoint, ChatGPT auth checks the ChatGPT path, and custom/AWS/local
    providers check configured HTTP endpoints when available.
    - Adds structured, redacted JSON output where `checks` is keyed by check
    id and `details` is a key/value object for support tooling.
    - Integrates doctor with feedback uploads by attaching a best-effort
    `codex-doctor-report.json` report and adding derived Sentry tags for
    overall status and failing/warning checks.
    - Updates the TUI feedback consent copy so users can see that the doctor
    report is included when logs/diagnostics are uploaded.
    - Updates the CLI bug issue template to ask reporters for `codex doctor
    --json` and render pasted reports as JSON.
    
    ## Example Output
    
    The examples below are sanitized from local smoke runs with `--no-color`
    so the structure is reviewable in plain text.

    ## How to Test
    
    1. Run `cargo run --bin codex -- doctor --no-color`.
    2. Confirm the detailed report is the default and includes promoted
    Notes, grouped sections, terminal details, state DB integrity, rollout
    stats, provider reachability, WebSocket diagnostics, and app-server
    status.
    3. Run `cargo run --bin codex -- doctor --summary --no-color`.
    4. Confirm the compact view keeps the same sections and summary counts
    but omits detailed key/value rows.
    5. Run `cargo run --bin codex -- doctor --json`.
    6. Confirm the output is redacted JSON, `checks` is an object keyed by
    check id, and each check's `details` is a key/value object.
    7. Preview the CLI bug issue template and confirm the `Codex doctor
    report` field appears after the terminal field, asks for `codex doctor
    --json`, and renders pasted output as JSON.
    8. Start a feedback flow that includes logs.
    9. Confirm the upload consent copy lists `codex-doctor-report.json`
    alongside the log attachments.

  • Add callback ids to local MCP OAuth redirects (#20237)
    ## Summary
    
    - Add a deterministic callback-id path segment to local MCP OAuth
    redirect URIs before starting authorization.
    - Derive the callback id from the normalized MCP server URL and encode
    it as a 12-character URL-safe hash.
    - Reuse the existing exact callback-path validation so OAuth completion
    only succeeds on the callback path that was sent in the redirect URI.
    
    ## Context
    
    Slack thread:
    https://openai.slack.com/archives/C087WB3AGCR/p1777480566571699
    
    That thread calls out the OAuth mix-up class of issue for MCP servers.
    The connector/App Connect flow already has a callback_id concept that
    binds the OAuth callback URL to the MCP app/server identity. Codex
    desktop's local MCP OAuth flow was still using a generic local callback
    path like `/callback`, so this PR adds the same shape to the shared
    local MCP OAuth helper.
    
    ## Behavior
    
    Before this change, local MCP OAuth used:
    
    - default local callback URL: `http://127.0.0.1:<port>/callback`
    - configured callback URL: `<configured callback URL>` unchanged
    
    After this change, Codex appends a deterministic callback-id segment:
    
    - default local callback URL:
    `http://127.0.0.1:<port>/callback/<callback_id>`
    - configured callback URL: `<configured callback path>/<callback_id>`
    
    The local callback server already compares the incoming request path
    against the path from the redirect URI. By appending the callback id
    before both authorization and callback validation, callbacks that arrive
    on the old generic path or a mismatched callback-id path are rejected.
    
    The callback id is bound to the MCP endpoint URL, including path and
    query, so path-based multi-tenant MCP deployments on the same origin do
    not share a callback path. URL fragments are ignored because they are
    not sent to the server.
    
    The change lives in `codex-rmcp-client`, so it covers both the normal
    desktop MCP OAuth login path and silent/plugin-triggered MCP OAuth login
    paths that use the same `perform_oauth_login_*` helpers.
    
    ## Scope and non-goals
    
    - This does not change the app-server protocol or desktop webview
    request shape.
    - This does not implement RFC 9207 `iss` validation; issuer validation
    is still useful when providers return `iss`.
    - This does not make arbitrary untrusted MCP servers safe to use. It
    specifically adds callback URL binding for the local MCP OAuth flow.
    
    ## Validation
    
    - `cargo fmt --all`
    - `cargo test -p codex-rmcp-client perform_oauth_login`
  • chore(config) rm Feature::CodexGitCommit (#22412)

    Removes the unused Feature::CodexGitCommit
    
    ## Testing
    - [x] tests pass
  • config: add strict config parsing (#20559)
    ## Why
    
    Codex intentionally ignores unknown `config.toml` fields by default so
    older and newer config files keep working across versions. That leniency
    also makes typo detection hard because misspelled or misplaced keys
    disappear silently.
    
    This change adds an opt-in strict config mode so users and tooling can
    fail fast on unrecognized config fields without changing the default
    permissive behavior.
    
    This feature is possible because `serde_ignored` exposes the exact
    signal Codex needs: it lets Codex run ordinary Serde deserialization
    while recording fields Serde would otherwise ignore. That avoids
    requiring `#[serde(deny_unknown_fields)]` across every config type and
    keeps strict validation opt-in around the existing config model.
    
    ## What Changed
    
    ### Added strict config validation
    
    - Added `serde_ignored`-based validation for `ConfigToml` in
    `codex-rs/config/src/strict_config.rs`.
    - Combined `serde_ignored` with `serde_path_to_error` so strict mode
    preserves typed config error paths while also collecting fields Serde
    would otherwise ignore.
    - Added strict-mode validation for unknown `[features]` keys, including
    keys that would otherwise be accepted by `FeaturesToml`'s flattened
    boolean map.
    - Kept typed config errors ahead of ignored-field reporting, so
    malformed known fields are reported before unknown-field diagnostics.
    - Added source-range diagnostics for top-level and nested unknown config
    fields, including non-file managed preference source names.
    
    ### Kept parsing single-pass per source
    
    - Reworked file and managed-config loading so strict validation reuses
    the already parsed `TomlValue` for that source.
    - For actual config files and managed config strings, the loader now
    reads once, parses once, and validates that same parsed value instead of
    deserializing multiple times.
    - Validated `-c` / `--config` override layers with the same
    base-directory context used for normal relative-path resolution, so
    unknown override keys are still reported when another override contains
    a relative path.
    
    ### Scoped `--strict-config` to config-heavy entry points
    
    - Added support for `--strict-config` on the main config-loading entry
    points where it is most useful:
      - `codex`
      - `codex resume`
      - `codex fork`
      - `codex exec`
      - `codex review`
      - `codex mcp-server`
      - `codex app-server` when running the server itself
      - the standalone `codex-app-server` binary
      - the standalone `codex-exec` binary
    - Commands outside that set now reject `--strict-config` early with
    targeted errors instead of accepting it everywhere through shared CLI
    plumbing.
    - `codex app-server` subcommands such as `proxy`, `daemon`, and
    `generate-*` are intentionally excluded from the first rollout.
    - When app-server strict mode sees invalid config, app-server exits with
    the config error instead of logging a warning and continuing with
    defaults.
    - Introduced a dedicated `ReviewCommand` wrapper in `codex-rs/cli`
    instead of extending shared `ReviewArgs`, so `--strict-config` stays on
    the outer config-loading command surface and does not become part of the
    reusable review payload used by `codex exec review`.
    
    ### Coverage
    
    - Added tests for top-level and nested unknown config fields, unknown
    `[features]` keys, typed-error precedence, source-location reporting,
    and non-file managed preference source names.
    - Added CLI coverage showing invalid `--enable`, invalid `--disable`,
    and unknown `-c` overrides still error when `--strict-config` is
    present, including compound-looking feature names such as
    `multi_agent_v2.subagent_usage_hint_text`.
    - Added integration coverage showing both `codex app-server
    --strict-config` and standalone `codex-app-server --strict-config` exit
    with an error for unknown config fields instead of starting with
    fallback defaults.
    - Added coverage showing unsupported command surfaces reject
    `--strict-config` with explicit errors.
    
    ## Example Usage
    
    Run Codex with strict config validation enabled:
    
    ```shell
    codex --strict-config
    ```
    
    Strict config mode is also available on the supported config-heavy
    subcommands:
    
    ```shell
    codex --strict-config exec "explain this repository"
    codex review --strict-config --uncommitted
    codex mcp-server --strict-config
    codex app-server --strict-config --listen off
    codex-app-server --strict-config --listen off
    ```
    
    For example, if `~/.codex/config.toml` contains a typo in a key name:
    
    ```toml
    model = "gpt-5"
    approval_polic = "on-request"
    ```
    
    then `codex --strict-config` reports the misspelled key instead of
    silently ignoring it. The path is shortened to `~` here for readability:
    
    ```text
    $ codex --strict-config
    Error loading config.toml:
    ~/.codex/config.toml:2:1: unknown configuration field `approval_polic`
      |
    2 | approval_polic = "on-request"
      | ^^^^^^^^^^^^^^
    ```
    
    Without `--strict-config`, Codex keeps the existing permissive behavior
    and ignores the unknown key.
    
    Strict config mode also validates ad-hoc `-c` / `--config` overrides:
    
    ```text
    $ codex --strict-config -c foo=bar
    Error: unknown configuration field `foo` in -c/--config override
    
    $ codex --strict-config -c features.foo=true
    Error: unknown configuration field `features.foo` in -c/--config override
    ```
    
    Invalid feature toggles are rejected too, including values that look
    like nested config paths:
    
    ```text
    $ codex --strict-config --enable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --disable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --enable multi_agent_v2.subagent_usage_hint_text
    Error: Unknown feature flag: multi_agent_v2.subagent_usage_hint_text
    ```
    
    Unsupported commands reject the flag explicitly:
    
    ```text
    $ codex --strict-config cloud list
    Error: `--strict-config` is not supported for `codex cloud`
    ```
    
    ## Verification
    
    The `codex-cli` `strict_config` tests cover invalid `--enable`, invalid
    `--disable`, the compound `multi_agent_v2.subagent_usage_hint_text`
    case, unknown `-c` overrides, app-server strict startup failure through
    `codex app-server`, and rejection for unsupported commands such as
    `codex cloud`, `codex mcp`, `codex remote-control`, and `codex
    app-server proxy`.
    
    The config and config-loader tests cover unknown top-level fields,
    unknown nested fields, unknown `[features]` keys, source-location
    reporting, non-file managed config sources, and `-c` validation for keys
    such as `features.foo`.
    
    The app-server test suite covers standalone `codex-app-server
    --strict-config` startup failure for an unknown config field.
    
    ## Documentation
    
    The Codex CLI docs on developers.openai.com/codex should mention
    `--strict-config` as an opt-in validation mode for supported
    config-heavy entry points once this ships.
  • feat: memories ext (#22498)
    First memories extension implementation
    Based on memories-mcp tools
  • 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.
  • Refactor extension tools onto shared ToolExecutor (#22369)
    ## Why
    
    Extension tools were split across two public runtime contracts:
    `codex-tool-api` exposed `ToolBundle` plus its own call/spec/error
    types, while core native tools used `codex_tools::ToolExecutor`. That
    made contributed tool specs and execution behavior easy to drift apart
    and added another crate boundary for what should be one executable-tool
    seam.
    
    This PR makes `ToolExecutor` the single runtime contract and keeps
    extension-specific pinning in `codex-extension-api`.
    
    ## Remaining todo
    
    https://github.com/openai/codex/pull/22369/changes#diff-b935ea8245c3ce568a30cff660175fa6390b66b872ae409e1e2e965738250741R5
    Either generic `Invocation` or sub-extract the `ToolCall` and clean
    `ToolInvocation`
    
    ## What changed
    
    - Removed the `codex-tool-api` workspace crate and its dependencies from
    core and `codex-extension-api`.
    - Made `codex_tools::ToolExecutor` object-safe with `async_trait` so
    extension contributors can return a dyn executor.
    - Added the extension-facing aliases under
    `ext/extension-api/src/contributors/tools.rs`, including
    `ExtensionToolExecutor = dyn ToolExecutor<ToolCall, Output =
    ExtensionToolOutput>`.
    - Changed `ToolContributor::tools` to return extension executors
    directly instead of `ToolBundle`s.
    - Updated core’s extension tool handler/registry/router path to adapt
    those extension executors into the existing native `ToolInvocation`
    runtime path.
    - Added focused coverage for extension tools being registered,
    model-visible, dispatchable, and not replacing built-in tools.
    
    ## Verification
    
    - `cargo test -p codex-tools`
    - `cargo test -p codex-extension-api`
  • feat: extract shared tool executor interface (#22359)
    ## Why
    
    Codex still models model-visible tools and executable behavior largely
    inside `codex-core`, which makes it harder to evolve the tool system
    toward a single reusable abstraction for built-ins, MCP-backed tools,
    dynamic tools, and later tools injected from outside core.
    
    This PR takes the next incremental step in that direction by moving the
    common execution-facing pieces out of core and separating them from
    core-only orchestration. The intent is to let shared tool abstractions
    improve in one place, while `codex-core` keeps the parts that are still
    inherently host-specific today, such as `ToolInvocation`, dispatch
    wiring, and hook integration.
    
    This PR is mostly moving things around. The only interesting piece is
    this abstraction:
    https://github.com/openai/codex/pull/22359/changes#diff-81af519002548ba51ed102bdaaf77e081d40a1e73a6e5f9b104bbbc96a6f1b3dR13
    
    ## What changed
    
    - Added `codex_tools::ToolExecutor<Invocation>` as the shared execution
    trait for model-visible tools.
    - Moved the reusable execution support types from `codex-core` into
    `codex-tools`:
      - `FunctionCallError`
      - `ToolPayload`
      - `ToolOutput`
    - Refactored core tool implementations so that execution behavior lives
    on `ToolExecutor<ToolInvocation>`, while `ToolHandler` remains the
    core-local extension point for hook payloads, telemetry tags, diff
    consumers, and other orchestration concerns.
    - Kept the registry and dispatch flow behaviorally unchanged while
    making the shared/extracted boundary explicit across built-in, MCP,
    dynamic, extension-backed, shell, and multi-agent tool handlers.
    
    ## Verification
    
    - `cargo test -p codex-tools`
    - `just fix -p codex-tools`
    - `just fix -p codex-core`
    - `cargo test -p codex-core` progressed through the updated tool
    surfaces and then hit the existing unrelated multi-agent stack overflow
    in
    `tools::handlers::multi_agents::tests::tool_handlers_cascade_close_and_resume_and_keep_explicitly_closed_subtrees_closed`.
  • Add support for UDS in codex --remote (#22414)
    ## Why
    
    Added support for UDS connections in `codex --remote`.
    
    TUI also now connects to local app-server using UDS by default if it is
    running and set to listen to UDS connection.
    
    ## What Changed
    
    - Introduced `RemoteAppServerEndpoint` with `WebSocket` and `UnixSocket`
    variants.
    - Reused the existing JSON-RPC-over-WebSocket protocol over either a TCP
    WebSocket stream or a UDS stream.
    - Updated `codex --remote` to accept `ws://host:port`,
    `wss://host:port`, `unix://`, and `unix://PATH`.
    - Kept `--remote-auth-token-env` restricted to `wss://` and loopback
    `ws://` remotes.
    - Added a fast TUI startup probe for the default daemon socket, falling
    back to the embedded app server when the daemon is absent or
    unresponsive.
    
    ## Verification
    
    - Manually verified that the updated remote flow works.
    - Added coverage for UDS remote round trips, WebSocket auth headers,
    auth-token transport policy, remote address parsing, and missing-daemon
    fallback.
    - Ran focused remote test coverage locally.
  • Remove CODEX_RS_SSE_FIXTURE test hook (#22413)
    ## Why
    
    `CODEX_RS_SSE_FIXTURE` let integration-style CLI, exec, and TUI tests
    bypass the normal Responses transport by reading SSE from local files.
    That kept test-only behavior wired through production client code. The
    affected tests can stay hermetic by using the existing
    `core_test_support::responses` mock server and passing `openai_base_url`
    instead.
    
    ## What Changed
    
    - Removed the `CODEX_RS_SSE_FIXTURE` flag,
    `codex_api::stream_from_fixture`, the `env-flags` dependency, and the
    checked-in SSE fixture files.
    - Repointed the affected core, exec, and TUI tests at `MockServer` with
    the existing SSE event constructors.
    - Removed the Bazel test data plumbing for the deleted fixtures and
    refreshed cargo/Bazel lock state.
    
    ## Verification
    
    - `cargo build -p codex-cli`
    - `cargo test -p codex-api`
    - `cargo test -p codex-core --test all responses_api_stream_cli`
    - `cargo test -p codex-core --test all
    integration_creates_and_checks_session_file`
    - `cargo test -p codex-exec --test all ephemeral`
    - `cargo test -p codex-exec --test all resume`
    - `cargo test -p codex-tui --test all
    resume_startup_does_not_consume_model_availability_nux_count`
    - `just bazel-lock-update`
    - `just bazel-lock-check`
    - `just fix -p codex-api -p codex-core -p codex-exec -p codex-tui`
    - `git diff --check`
