## Why
Extension-contributed tools need to emit visible turn items through
Codex's normal event and persistence pipeline.
## What
- Add `TurnItemEmitter` to extension `ToolCall`s and route the core
implementation through `Session::emit_turn_item_*`.
- Hold weak session and turn references so retained tool calls cannot
keep host state alive.
- Provide a no-op emitter for extension test callers.
## Test Plan
- `just test -p codex-core -E
'test(passes_turn_fields_and_scoped_turn_item_emitter_to_extension_call)'`
---------

Summary
- Add TurnErrorInput and TurnLifecycleContributor::on_turn_error to the
extension API.
- Emit the turn-error lifecycle from core turn error paths, including
usage limit failures.
- Add direct lifecycle coverage for the emitted error facts and stores.
Tests
- just fmt
- git diff --check
- Not run: full tests or clippy (per instructions)
Summary: add session source and persistent-state availability to
ThreadStartInput; populate them from session init; update existing goal
test harness constructors. Tests: just fmt; git diff --check. No full
tests or clippy run per request.
## Why
Guardian reviews already emit analytics events, but we do not expose
aggregate OpenTelemetry metrics for review volume, latency, token usage,
or terminal outcomes. That makes it harder to monitor Guardian behavior
during rollouts and to compare review outcomes by source, action type,
session kind, model, and failure mode.
## What Changed
- Added Guardian review metric names for count, total duration, time to
first token, and token usage in `codex-rs/otel`.
- Added `core/src/guardian/metrics.rs` to convert
`GuardianReviewAnalyticsResult` into sanitized metric tags covering
decision, terminal status, failure reason, approval request source,
reviewed action, session kind, risk/outcome, model, reasoning effort,
and context/truncation state.
- Emitted the new metrics from `track_guardian_review` for each terminal
Guardian review result.
## Testing
- Added
`guardian_review_metrics_record_counts_durations_and_token_usage`, which
verifies the emitted count, duration, TTFT, token usage histograms, and
tag set through the in-memory metrics exporter.
## Summary
- Add the required `/*parent_thread_id*/` argument comment at the
Guardian review session test callsite flagged by CI.
## Validation
- `just fmt`
- Not run: clippy/tests, per request; CI will cover them.

## Why
Config loading should not create or write-authorize the memories root
just because memory support exists. Memory startup is the code path that
actually materializes that tree.
## What
- Stop creating the memories root during Config load and remove it from
legacy workspace-write projections.
- Grant the memories root read access only when the memories feature and
use_memories are enabled.
- Create the memories root inside memories startup before seeding
extension instructions.
- Update config and startup tests around the ownership boundary.
## Tests

- just test -p codex-memories-write memories_startup_creates_memory_root
Note: a broader just test -p codex-core run is not clean in this
sandbox; it hit missing test_stdio_server plus seatbelt, realtime, and
environment-sensitive failures. The changed config tests above pass.
## Why
Dynamic tools are defined at thread start and already stored in rollout
`SessionMeta`, which restores resumed and forked sessions. Persisting
the same tools through SQLite creates a second runtime persistence path
that is unnecessary prework for the explicit namespace refactor.
## What changed
- Restore missing thread-start dynamic tools directly from rollout
history, including when SQLite is enabled.
- Remove SQLite dynamic-tool reads, writes, backfill, and thread
metadata patch plumbing.
- Add SQLite-enabled resume integration coverage that verifies a
rollout-defined dynamic tool is still sent after resume.
## Compatibility
The existing `thread_dynamic_tools` table is intentionally not dropped
even though it's now unused. Older Codex binaries are allowed to open
databases migrated by newer binaries and still reference this table;
dropping it would break that mixed-version path. See
[here](https://github.com/openai/codex/blob/main/codex-rs/state/src/migrations.rs#L10-L11).
## Verification
- `just test -p codex-state -p codex-rollout -p codex-thread-store`
- `just test -p codex-core --test all
resume_restores_dynamic_tools_from_rollout_with_sqlite_enabled`
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.
## Why
Interrupted `shell_command` calls can race with the outer tool-dispatch
cancellation path. When that happens, the runtime future may be dropped
before the spawned process gets a chance to run `SIGTERM` cleanup. For
bwrapd-backed Linux sandbox commands, that can leave synthetic
protected-path mount bookkeeping such as `.git/.codex` registrations
under `/tmp` behind after a TUI interruption.
The relevant cancellation points are the outer dispatch race in
[`core/src/tools/parallel.rs`](bd184ba847/codex-rs/core/src/tools/parallel.rs (L91-L132))
and the process shutdown logic in
[`core/src/exec.rs`](bd184ba847/codex-rs/core/src/exec.rs (L1367-L1393)).
## What changed
- Keep `shell_command` dispatch alive long enough for the runtime to
finish cancellation cleanup instead of immediately returning the
synthetic aborted response.
- Fold shell-turn cancellation into the existing `ExecExpiration` path
in
[`core/src/tools/runtimes/shell.rs`](bd184ba847/codex-rs/core/src/tools/runtimes/shell.rs (L267-L274)),
so cancellation and timeout behavior stay centralized.
- On cancellation, send `SIGTERM` first, wait briefly for cleanup to
run, then hard-kill any remaining descendants in the original process
group.
- Treat `ESRCH` as an already-gone process-group cleanup case in
`codex-utils-pty`, which keeps best-effort teardown from surfacing a
stale-process race as an error.
## Verification
- `cargo test -p codex-core cancellation`
- Added regression coverage for:
- `shell_tool_cancellation_waits_for_runtime_cleanup`
- `process_exec_tool_call_cancellation_allows_sigterm_cleanup`
Client-side namespace tools are now supported by bedrock. Enable
`namespace_tools` for the Amazon Bedrock provider while continuing to
disable unsupported hosted tools such as image generation and web
search.
## Why
Interrupting an active turn is currently fixed to `Esc`, which is easy
to hit accidentally and cannot be customized through `/keymap`. This
gives users a less accidental binding while preserving the existing
default.
## What Changed
- Adds `tui.keymap.chat.interrupt_turn` to `/keymap`, defaulting to
`esc` and supporting remapping or unbinding.
- Uses the configured interrupt binding for running-turn status, queued
steer interruption, and `request_user_input`, including the visible
hints.
- Preserves local `Esc` behavior for popups, Vim insert mode, and
`/agent` editing while validating conflicts with fixed/backtrack and
request-input navigation bindings.
- Adds behavior and snapshot coverage for remapped interruption paths.
## How to Test
1. Run Codex and open `/keymap`, then set **Interrupt Turn** to `f12`.
2. Start a turn and confirm `Esc` no longer interrupts it while `f12`
does; the running hint should display `f12 to interrupt`.
3. Queue a steer while a turn is running and confirm the preview
displays `f12`; pressing it should interrupt and submit the steer
immediately.
4. Trigger a `request_user_input` prompt and confirm its footer uses
`f12`; with notes open, `Esc` should still clear notes while `f12`
interrupts the turn.
5. Clear the Interrupt Turn binding and confirm the key-specific
interrupt hint is removed while `Ctrl+C` remains available.
Targeted validation:
- `just write-config-schema`
- `just fix -p codex-config`
- `just fix -p codex-tui`
- `just fmt`
- `just argument-comment-lint-from-source -p codex-config -p codex-tui`
- `just test -p codex-config`
- `cargo insta pending-snapshots --manifest-path tui/Cargo.toml`
- `just test -p codex-tui keymap_setup::tests`
- `just test -p codex-tui` (fails in two pre-existing guardian
feature-flag tests unrelated to this diff; the intentional picker
snapshot updates were reviewed and accepted)
## Why
Vim mode currently supports some normal-mode operators and motions, but
common text-object combinations like `ciw`, `daw`, `di(`, and
quote/bracket variants are still missing. That makes the composer feel
incomplete for users who expect operator + text object editing to work
inside prompts.
Closes#21383.
## What Changed
- Add Vim pending-state support for operator/text-object sequences.
- Add `c` as a normal-mode operator for text objects, so combinations
like `ciw` delete the object and enter insert mode.
- Support word, WORD, delimiter, and quote text objects:
- `iw`, `aw`, `iW`, `aW`
- `i(`, `a(`, `i)`, `a)`, `ib`, `ab`
- `i[`, `a[`, `i]`, `a]`
- `i{`, `a{`, `i}`, `a}`, `iB`, `aB`
- `i"`, `a"`, `i'`, `a'`, `i\``, `a\``
- Add configurable keymap entries and keymap picker coverage for the new
Vim text-object context.
- Regenerate the config schema and update keymap picker snapshots.
## How to Test
Manual smoke test:
1. Start Codex with Vim composer mode enabled.
2. Type a draft such as:
```text
alpha beta gamma
call(foo[bar], {"x": "hello world"})
say "one \"two\" three" now
```
3. Put the cursor on `beta`, press `ciw`, and confirm `beta` is removed
and the composer enters insert mode.
4. Escape back to normal mode, put the cursor on `gamma`, press `daw`,
and confirm `gamma` plus surrounding whitespace is removed.
5. Put the cursor inside `foo[bar]`, press `di[`, and confirm only `bar`
is removed.
6. Put the cursor inside `call(...)`, press `da(`, and confirm the whole
parenthesized section is removed.
7. Put the cursor inside the quoted text, press `ci"`, and confirm the
quote contents are removed and insert mode starts.
8. Verify cancellation does not edit text: press `d` then `Esc`, and
press `d` then `i` then `Esc`.
Targeted tests:
- `cargo test -p codex-tui --lib vim_`
- `cargo nextest run -p codex-tui keymap_setup::tests`
Additional local checks:
- `just write-config-schema`
- `just fmt`
- `just fix -p codex-tui`
- `git diff --check`
- `cargo insta pending-snapshots --manifest-path tui/Cargo.toml`
Local full-suite note: `just test -p codex-tui` ran to completion. The
keymap snapshot failures were expected and accepted. Two unrelated
guardian feature-flag tests still fail locally:
-
`app::tests::update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default`
-
`app::tests::update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`
`just argument-comment-lint` is currently blocked locally by Bazel
analysis before the lint runs because `compiler-rt` has an empty
`include/sanitizer/*.h` glob in the local Bazel cache. The touched Rust
diff was manually inspected for opaque positional literals.
## Summary
- Add `request_kind` values for foreground turn, startup prewarm,
compaction, and detached memory model requests.
- Attach compaction dispatch metadata to local Responses, legacy
`/v1/responses/compact`, and remote v2 compact requests.
- Add the existing logical context-window identifier as `window_id` on
turn-owned model request metadata.
- Keep identity fields optional for detached memory requests, while
still emitting `request_kind="memory"` in non-git/no-sandbox workspaces.
## Root Cause
`x-codex-turn-metadata` has more than one producer. Foreground turns and
compaction requests own a real turn and should carry that turn identity.
Detached memory stage-one requests do not own a foreground turn, so
absent identity fields are valid rather than missing data. Startup
websocket prewarm is also a model request, but it has `generate=false`
and must not be counted as a foreground turn.
`thread_source` or session source identifies where a thread came from
(for example review, guardian, or another subagent). `request_kind`
identifies what the current outbound model request is doing (`turn`,
`prewarm`, `compaction`, or `memory`). A review or guardian thread can
issue either a normal turn request or a compaction request, so source
cannot replace request kind.
## Behavior / Impact
- Ordinary foreground requests send `request_kind="turn"`, their real
identity fields, and `window_id="<thread_id>:<window_generation>"`.
- Startup websocket warmup requests send `request_kind="prewarm"` so
they are not counted as foreground turns.
- Compaction requests send `request_kind="compaction"`, their real
owning turn identity, the existing `window_id`, and
`compaction.{trigger,reason,implementation,phase,strategy}`.
- Detached memory stage-one requests send `request_kind="memory"`
without `session_id`, `thread_id`, `turn_id`, or `window_id`; when no
workspace metadata exists, the kind-only header is still emitted.
- `session_id`, `thread_id`, `turn_id`, and `window_id` remain optional
in the header schema because detached memory requests do not own a
foreground turn or context window.
- `window_id` is not a new ID system: it is copied from the already-sent
`x-codex-window-id` / WS client metadata value at model-request dispatch
time.
- Existing `x-codex-window-id` HTTP/WS emission, value format,
generation advancement, resume behavior, and fork reset behavior are
unchanged.
- `request_kind`, `window_id`, and upstream turn-owned identity fields
remain schema-owned; input `responsesapi_client_metadata` cannot replace
their canonical values.
- No table, DAG, export, app-server API, or MCP `_meta` schema changes
are included.
A compaction attempt stopped by a pre-compact hook issues no model
request and therefore has no request header; its outcome remains in
analytics events. Status, error, duration, and token deltas also remain
analytics fields rather than request-header fields.
Future detached-memory attribution using a real initiating turn ID as
`trigger_turn_id` is intentionally not part of this PR.
## Sync With Main
- Final pushed head `716342e79` is rebased onto `origin/main@0d37db4b2`.
- The metadata conflict came from upstream `#24160`, which added
`forked_from_thread_id` on the same `turn_metadata` surface. Resolution
preserves that field and its protection from client metadata override
alongside this PR's request-kind, compaction, and window-id fields.
- While resolving the overlapping commits, I removed an accidental
recursive model-request overlay and a duplicate detached-memory header
builder before completing the rebase.
## Latency / User Experience Boundary
- Foreground turns perform no new filesystem, git, or network work. New
fields are inserted into metadata already serialized for outgoing
requests.
- Compaction issues the same model/HTTP requests with the same prompt,
model, service tier, and sampling settings; only metadata bytes change.
- Startup prewarm already sent metadata; it is now correctly classified
as `prewarm`.
- Non-git detached memory now sends a small kind-only metadata header
rather than no header.
- This client diff adds no user-visible latency mechanism beyond
negligible serialization and header bytes on already-existing requests.

## Why
The TUI Vim composer currently diverges from normal Vim editing in two
common workflows: pressing `e` repeatedly can remain stuck at an
existing word end, and normal mode does not support `C` for changing
through the end of the line. The existing `D` behavior also removes the
newline when the cursor is already at the line boundary, which makes the
new `C` action and existing deletion action surprising in multiline
prompts.
Closes#23926.
Closes#24238.
## What Changed
- Make normal-mode `e` advance from the current word end to the next
word end, including for operator motions such as `de`.
- Add configurable Vim normal-mode `change_to_line_end` behavior, bound
to `C` by default, which deletes to the end of the current line and
enters Insert mode.
- Keep the newline intact when `D` or `C` is pressed at the end-of-line
boundary.
- Add regression coverage for repeated `e`, `de`, `C`, and the multiline
`C`/`D` boundary behavior.
- Regenerate the config schema and update the keymap picker snapshots
for the new Vim action.
## How to Test
1. Run Codex with Vim composer mode enabled:
```bash
cd codex-rs
cargo run --bin codex -- -c tui.vim_mode_default=true
```
2. Enter `alpha beta gamma`, press `Esc`, `0`, then press `e`
repeatedly.
Confirm the cursor advances through the ends of `alpha`, `beta`, and
`gamma`.
3. Enter `hello world`, press `Esc`, `0`, `w`, then `C`.
Confirm `world` is deleted and the composer enters Insert mode.
4. Enter a multiline prompt with `hello` above `world`, press `Esc`,
`k`, `$`, and then `D`.
Confirm the newline is preserved and the two lines do not join.
5. At the same boundary, press `C` and type `!`.
Confirm the composer enters Insert mode and yields `hello!` above
`world`, preserving the newline.
Targeted automated verification:
- `just fix -p codex-tui`
- `just argument-comment-lint-from-source -p codex-tui -p codex-config`
- `cargo insta pending-snapshots` reports no pending snapshots.
- `just test -p codex-tui` validates the new Vim and keymap snapshot
coverage, but the command remains red due to two reproducible unrelated
failures in `app::tests::update_feature_flags_disabling_guardian_*`.
## Validation Note
The workspace-wide `just argument-comment-lint` form is currently
blocked during Bazel analysis by the existing LLVM `compiler-rt` missing
`include/sanitizer/*.h` failure; package-scoped source linting for the
changed Rust crates passed.
## Summary
- Change last-`n` fork truncation to start at the first fork-turn
boundary instead of returning the full rollout when the fork history is
shorter than the requested window.
- Add coverage for the startup-prefix case in both rollout truncation
tests and agent control spawn behavior.
- Ensure bounded forked children still rebuild context after the cached
prefix is truncated.
## Testing
- Added unit coverage for truncation behavior when the parent history is
under the requested fork-turn limit.
- Added an agent control test covering bounded fork spawn behavior with
startup context present.
- Not run (not requested).
## Summary
- Add the missing additional_context field to the guardian review
Op::UserInput test initializer.
## Test plan
- just fmt
- just test -p codex-core guardian_review
- just test -p codex-core (compiles, then fails on local environment
issues: sandbox-exec Operation not permitted, missing test_stdio_server
helper binary, and unrelated timeouts)
## Summary
Clear inherited legacy `notify` from Guardian review session config,
since we should not be passing auto review threads into `notify`
targets. Keeps legacy notify payload and hook runtime behavior unchanged
for normal user turns.
## Testing
- [x] add a Guardian config regression and dedicated Guardian
integration test so review sessions cannot inherit parent notify hooks
## Summary
- Bump the workspace Rust toolchain from `1.93.0` to `1.95.0` across
Cargo, Bazel, CI, release workflows, devcontainers, and the Codex
environment config.
- Refresh `MODULE.bazel.lock` so the Bazel Rust toolchain artifacts
match the new version.
- Leave purpose-specific toolchains unchanged, including the
`argument-comment-lint` nightly and the upstream `rusty_v8` `1.91.0`
build pin.
- Includes fixes for new lints from `just fix` and a few codex-authored
fixes for lints without a suggestion.
## Why
When a turn needs a follow-up request after tool output is recorded,
Codex can still appear stuck in `Thinking` before the next `/responses`
request is opened. The existing local trace showed the last completed
response and the absence of a new backend request, but it did not show
whether the stall was in tool-router preparation or later request setup.
Issue: N/A (internal incident investigation)
## What Changed
Added trace spans around the pre-stream tool-router handoff in
`core/src/session/turn.rs`, including the `built_tools` phase and the
MCP manager read lock.
Added per-server MCP tool-listing spans and trace breadcrumbs in
`codex-mcp/src/connection_manager.rs` with startup snapshot /
startup-complete state so a pending MCP client is visible in feedback
logs instead of looking like a silent hang.
## Verification
- `just fmt`
- `just test -p codex-mcp`
- `just test -p codex-core` (prior full rerun fails in this workspace on
unrelated integration tests: code-mode output length expectations, one
shell timeout formatting assertion, and shell snapshot timeouts; latest
review-fix rerun compiled and passed 1160 tests before I stopped the
abnormally slow unrelated suite)
## Why
`continuation_turn_id` was introduced to distinguish synthetic goal
continuation turns for the no-tool continuation suppression heuristic.
#20523 removed that heuristic, but left the marker behind. It is still
written and cleared without affecting any runtime decision.
## What Changed
- Remove `GoalRuntimeState::continuation_turn_id`.
- Remove the marker setter/clearer and their now-no-op start, finish,
and abort call sites.
## Testing
- Not run yet (deferred at request).
## Why
- Runtime analytics events report `thread_id`, which identifies the
individual thread emitting an event
- They don't report `session_id`, which identifies the shared session
for a root thread and its subagent threads
- Emitting both identifiers allows analytics to group related activity
## What Changed
- Adds `session_id` to relevant analytics events (thread_initalized,
turn, turn_steer, compaction, guardian_review)
- Tracks each thread's session ID in the analytics reducer so subsequent
thread scoped events emit the same value
- Carries the shared session ID through subagent initialization
## Verification
- `just test -p codex-analytics` validates event payloads and subagent
session grouping.
- Focused `codex-app-server` tests validate session IDs for thread,
turn, and steer events.
- Focused `codex-core` tests validate root and subagent session ID
propagation.
## Why
Older persisted rollouts can contain `input_image.detail` values of
`auto` or `low` from before `ImageDetail` was narrowed to
`high`/`original`. Current deserialization rejects those values, which
can make resume skip later compacted checkpoints and reconstruct an
oversized raw suffix before the next compaction attempt.
Confirmed Sentry reports fixed by this compatibility path:
- [CODEX-1H3F](https://openai.sentry.io/issues/7500642496/)
- [CODEX-1H6N](https://openai.sentry.io/issues/7501025347/)
- [CODEX-1JDP](https://openai.sentry.io/issues/7504549065/)
- [CODEX-1HW6](https://openai.sentry.io/issues/7503407986/)
## Background
[openai/codex#20693](https://github.com/openai/codex/pull/20693) added
image-detail plumbing for app-server `UserInput` so input images could
explicitly request `detail: original`. The Slack discussion behind that
PR was about ScreenSpot / bridge evals where user input images were
resized, while tool output images already had MCP/code-mode ways to
request image detail.
In review, the intended new API surface was narrowed to `high` and
`original`: default to `high`, allow `original` when callers need
unchanged image handling, and avoid encouraging new `auto` or `low`
usage. That policy still makes sense for newly emitted values.
The missing compatibility piece is persisted history. Older rollouts can
already contain `auto` and `low`, and resume reconstructs typed history
by deserializing those rollout records. Rejecting old values at that
boundary causes valid compacted checkpoints to be skipped. This PR
restores `auto` and `low` as real variants so old records deserialize
and round-trip without being rewritten as `high`, while product paths
can continue to default to `high` and avoid emitting `auto` for new
behavior.
## What changed
- Restored `ImageDetail::Auto` and `ImageDetail::Low` as first-class
protocol values.
- Preserved `auto`/`low` through rollout deserialization, MCP image
metadata, code-mode image output, and schema/type generation.
- Kept local image byte handling conservative: only `original` switches
to original-resolution loading; `auto`/`low`/`high` continue through the
resize-to-fit path while retaining their detail value.
- Added regression coverage for enum round-tripping and code-mode `low`
detail handling.
## Testing
- `just write-app-server-schema`
- `just test -p codex-protocol`
- `just test -p codex-tools`
- `just test -p codex-code-mode`
- `just test -p codex-app-server-protocol`
- `just test -p codex-core
suite::rmcp_client::stdio_image_responses_preserve_original_detail_metadata`
- `just test -p codex-core
suite::code_mode::code_mode_can_use_mcp_image_result_with_image_helper`
- Loaded broken rollouts on local fixed builds, and started/completed
new turns.
I also attempted `just test -p codex-core`; the local broad run did not
finish green: 2559 tests run, 2467 passed, 55 flaky, 91 failed, 1 timed
out. The failures were broad timeout/deadline failures across unrelated
areas; targeted changed-path core tests above passed.
## Why
Remote image submissions currently wrap native `input_image` spans in
literal `<image>` and `</image>` text spans. Those extra prompt tokens
add structure without providing label or routing information.
## What Changed
- Serialize `UserInput::Image` directly as an `input_image` content
span.
- Preserve named local-image framing and legacy wrapper parsing for
labeled attachments and existing histories.
- Update existing request-shape expectations for drag-and-drop images,
model switching, and compaction.
## Validation
- `just test -p codex-protocol`
- Focused `codex-core` run covering
`drag_drop_image_persists_rollout_request_shape`,
`model_change_from_image_to_text_strips_prior_image_content`, and
`snapshot_request_shape_pre_turn_compaction_including_incoming_user_message`
## Notes
- A broader `just test -p codex-core` run was attempted; the affected
tests passed, while the overall run failed in unrelated CLI, MCP, and
tooling tests plus a `thread_manager` timeout.
## Why
The Windows sandbox runner still carried the old `SandboxPolicy`
compatibility path even though core now computes `PermissionProfile`.
That meant Windows command-runner execution could only see the legacy
projection, so profile-only filesystem rules such as deny globs were not
part of the runner input.
## What Changed
- Removed the Windows-local `SandboxPolicy` parser/export and deleted
`windows-sandbox-rs/src/policy.rs`.
- Changed restricted-token capture/session setup, elevated setup,
world-writable audit, read-root grant, and command-runner session APIs
to accept `PermissionProfile` plus the profile cwd.
- Bumped the elevated command-runner IPC protocol to version 2 because
`SpawnRequest` now carries `permission_profile` /
`permission_profile_cwd` instead of the legacy `policy_json_or_preset` /
`sandbox_policy_cwd` fields.
- Updated core exec, unified exec, debug-sandbox, TUI setup/grant flows,
and app-server setup to pass the actual effective `PermissionProfile`.
- Left regression coverage asserting the old IPC policy fields are
absent and the runner serializes tagged `PermissionProfile` JSON.
## Verification
- `cargo test -p codex-windows-sandbox`
- `cargo test -p codex-core windows_sandbox`
- `cargo test -p codex-app-server
request_processors::windows_sandbox_processor`
- `just fix -p codex-windows-sandbox -p codex-core -p codex-app-server
-p codex-cli -p codex-tui`
- `just fix -p codex-cli -p codex-tui`
- `just fix -p codex-windows-sandbox -p codex-tui`
- `rg "\\bSandboxPolicy\\b" codex-rs/windows-sandbox-rs` returned no
matches.
Note: `cargo test -p codex-cli` was attempted but did not reach crate
tests because local disk filled while compiling dependencies (`No space
left on device`). The targeted clippy pass compiled the affected CLI/TUI
surfaces afterward.

## Why
When Codex calls responsesapi, we currently send `session_id`,
`thread_id`, and `turn_id` among other things as
`client_metadata["x-codex-turn-metadata"]`. This PR adds
`forked_from_thread_id` which helps explain the "lineage" of a forked
thread.
## What's changed
- Track the immediate history source copied into a forked thread through
thread/session creation, including subagent and review turn metadata
paths.
- Include `forked_from_thread_id` in Codex turn metadata while
preventing turn-scoped Responses API client metadata from overwriting
Codex-owned lineage fields.
- Add coverage for fork lineage in turn metadata and the app-server
Responses API request path.
## Summary
Adds experimental `additionalContext` support to `turn/start` and
`turn/steer` so clients can provide ephemeral external context, such as
browser or automation state, without turning that plumbing into a
visible user prompt or triggering user-prompt lifecycle behavior.
## API Shape
The parameter shape is:
```ts
additionalContext?: Record<string, {
value: string
kind: "untrusted" | "application"
}> | null
```
Example:
```json
{
"additionalContext": {
"browser_info": {
"value": "Active tab is CI failures.",
"kind": "untrusted"
},
"automation_info": {
"value": "CI rerun is in progress.",
"kind": "application"
}
}
}
```
The keys are opaque and caller-defined.
## Context Injection
When provided, accepted entries are inserted into model context as
hidden contextual message items, not as visible thread user-message
items.
`kind: "untrusted"` entries are inserted with role `user`:
```text
<external_${key}>${value}</external_${key}>
```
`kind: "application"` entries are inserted with role `developer`:
```text
<${key}>${value}</${key}>
```
Values are not escaped. Each value is truncated to 1k approximate tokens
before wrapping.
For `turn/start`, accepted additional context is inserted before normal
user input. For `turn/steer`, additional context is merged only when the
steer includes non-empty user input; context-only steers still reject as
empty input.
## Dedupe Strategy
`AdditionalContextStore` lives on session state and stores the latest
complete additional-context map.
Each `turn/start` or non-empty `turn/steer` treats its
`additionalContext` as the current complete set of values. Entries are
injected only when the key is new or the exact entry for that key
changed, including `value` or `kind`. After merging, the store is
replaced with the provided map, so omitted keys are removed from the
retained set and can be injected again later if reintroduced.
Omitting `additionalContext`, passing `null`, or passing an empty object
resets the store to empty and injects nothing.
## What Changed
- Threads experimental v2 `additionalContext` through app-server into
core turn start and steer handling.
- Adds separate contextual fragment types for untrusted user-role
context and application developer-role context.
- Uses pending response input items so additional context can be
combined with normal user input without treating it as prompt text.
- Adds integration coverage for start/steer flow, role routing,
dedupe/reset behavior, deletion/re-add behavior, hook-blocked input
behavior, empty context-only steer rejection, external-fragment marker
matching, and truncation.
## 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
hosted_tools_follow_provider_auth_model_and_config_gates`
## Summary
Generated memory rows and their stage-one/stage-two job state currently
live in `state_5.sqlite` alongside thread metadata. That makes memory
cleanup and regeneration share the main state schema even though those
rows are memory-pipeline data and can be rebuilt independently from the
durable thread records.
This PR moves the memory-owned tables into a dedicated
`memories_1.sqlite` runtime database while keeping thread metadata in
`state_5.sqlite`.
## Changes
- Adds a separate memories DB runtime, migrator, path helpers, telemetry
kind, and Bazel compile data for `state/memory_migrations`.
- Introduces `MemoryStore` behind `StateRuntime::memories()` and moves
memory table/job operations onto that store.
- Drops the old memory tables from the state DB and recreates their
schema in `state/memory_migrations/0001_memories.sql`.
- Updates memory startup, citation usage tracking, rollout pollution
handling, `debug clear-memories`, and app-server `memory/reset` to
operate through the memories DB.
- Preserves cross-DB behavior by hydrating thread metadata from the
state DB when selecting visible memory outputs and checking stage-one
staleness.
## Verification
- Added/updated `codex-state` tests for deleted-thread memory visibility
and already-polluted phase-two enqueue behavior.
- Updated `debug clear-memories`, app-server `memory/reset`, and
memories startup tests to seed and assert memory rows through
`memories_1.sqlite`.
## Why
The
`approving_apply_patch_for_session_skips_future_prompts_for_same_file`
integration test writes `apply_patch_allow_session.txt` under the
process cwd while exercising outside-workspace patch approval behavior.
With `just test` now being the normal validation path, that file can be
left behind in the checkout when the test runs or fails, creating
confusing untracked state.
## What changed
- Registers the resolved `apply_patch_allow_session.txt` path with
`tempfile::TempPath` before the test removes and recreates it through
`apply_patch`.
- Preserves the existing outside-workspace path shape so the approval
behavior under test does not change.
- Lets `TempPath` remove the generated file when the test exits,
including panic paths.
## Verification
- `just test -p codex-core --test all
approving_apply_patch_for_session_skips_future_prompts_for_same_file`
## Why
`codex.task.compact` only distinguished `local` vs `remote`, which made
it hard to answer simple counter questions in Statsig. Manual `/compact`
and automatic compaction were collapsed together, and the legacy remote
path was also collapsed with `remote_compaction_v2`.
## What Changed
- route `codex.task.compact` through a shared helper in
`core/src/tasks/mod.rs`
- add a `manual=true|false` tag so manual and automatic compaction can
be counted separately
- split the remote tag into `remote` and `remote_v2`
- emit the metric from the inline auto-compaction path in
`core/src/session/turn.rs` as well as the manual `CompactTask` path in
`core/src/tasks/compact.rs`
- add focused unit coverage for the new tag shapes in
`core/src/tasks/mod_tests.rs`
## Verification
- added unit coverage in `core/src/tasks/mod_tests.rs` covering manual
`remote_v2` tags and automatic `local` tags
## Why
Users who opt into named permission profiles through
`default_permissions` or `[permissions.*]` should stay in named-profile
semantics when they open `/permissions`. The legacy picker rewrites
those users into anonymous preset state, which loses the active profile
identity and hides custom configured profiles.
## What changed
- Switch `/permissions` to a profile-aware picker when profile mode is
active.
- Show friendly built-in labels instead of raw `:` profile syntax.
- Include configured custom profiles and their descriptions in the
picker.
- Route selections through the split TUI profile-selection flow below
this PR.
- Add TUI snapshots and regression coverage for built-ins, custom
profiles, and conflicting legacy runtime overrides.
## Stack
1. [#22931](https://github.com/openai/codex/pull/22931):
runtime/session/network propagation for active permission profiles.
2. [#23708](https://github.com/openai/codex/pull/23708): TUI selection
plumbing and guardrail flow.
3. **This PR**: profile-aware `/permissions` menu and custom profile
display.
## UX impact
In profile mode, `/permissions` shows the same human-facing built-ins
users already know:
```text
Default
Auto-review
Full Access
Read Only
locked-down
web-enabled
```
Selecting `locked-down` keeps `active_permission_profile =
Some("locked-down")`; selecting a built-in keeps the friendly label
while switching to its named built-in profile.

## Validation
- `git diff --cached --check` before commit.
- Full test run skipped at the user request while pushing the split
stack.
## Why
The memories extension already has dedicated `list`, `read`, `search`,
and `add_ad_hoc_note` tools, but app-server registration was still
disabled. The memories app collaborator needs an explicit config switch
so those native extension tools can be exposed intentionally, without
making ordinary memory prompt usage automatically register the dedicated
tool surface.
## What changed
- Added `[memories].dedicated_tools`, defaulting to `false`, to
`MemoriesToml` / `MemoriesConfig`.
- Regenerated `core/config.schema.json` for the new setting.
- Registered the memories extension as a `ToolContributor`, while
keeping tool contribution gated on both memories being enabled and
`dedicated_tools = true`.
- Added tests for the disabled default, the enabled dedicated-tools
path, and installer registration.
## Verification
- `just test -p codex-config -p codex-memories-extension`
## Why
The `non_prefixed_mcp_tool_names` feature should be applied where MCP
tools become model-visible, not by remapping names later in core.
Keeping the decision in `McpConnectionManager` construction makes
`ToolInfo` the single shaped view that spec building, deferred tool
search, routing, and unavailable-tool placeholders can consume directly.
This also preserves the existing external behavior while the feature is
off, and keeps the feature-on behavior for code mode and hooks explicit
at the manager boundary.
## What Changed
- Add `McpToolNameMode` to `codex-mcp` and flow it through `McpConfig`
into `McpConnectionManager::new`.
- Normalize MCP `ToolInfo` names in the manager using either
legacy-prefixed namespaces or non-prefixed namespaces; the legacy path
adds `mcp__` without restoring the old trailing namespace suffix.
- Remove the core-side MCP name remapping path so specs, tool search,
session resolution, and unavailable-tool placeholder construction use
the manager-provided `ToolName` values directly.
- Keep code mode flattening on the `__` namespace separator.
- Preserve hook compatibility by giving non-prefixed MCP hook names
legacy `mcp__...` matcher aliases.
- Add/adjust integration and unit coverage for non-prefixed code-mode
behavior, hook matching with the feature on and off, and manager-level
legacy prefixing.

## Why
`ActiveTurn` already runs at most one task: starting a task requires
that no task is present, and replacement aborts existing work first.
Representing that state as an `IndexMap` leaves a multi-task shape for a
single-task invariant and makes each lifecycle lookup operate like a
collection lookup.
The slot remains optional because goal continuation uses an empty active
turn as a reservation while deciding whether to start continuation work.
## What changed
- Replace `ActiveTurn.tasks` with `task: Option<RunningTask>`.
- Update task abort/completion, session lookup and steering, input-queue
matching, goal reservation, and network-approval lookup to operate on
the singular slot.
- Mutate the singular task slot directly instead of retaining
collection-era add/remove/take helpers.
- Record token usage on the completing active task span without a
regular-task-only opt-in flag.
## Validation

## Why
#23951 added remote compaction v2 retries, but it left the retry and WS
-> HTTPS fallback behavior duplicated between normal Responses turns and
compaction. This follow-up centralizes the common retry handling so
future changes to fallback, retry delay, retry notifications, and retry
sleep do not have to be kept in sync across both callsites.
## What changed
- Added `core/src/responses_retry.rs` with a shared handler for
retryable Responses stream errors.
- Reused that handler from normal turn sampling and remote compaction
v2.
- Kept each callsite responsible for its retry budget: normal turns
still use `stream_max_retries`, while compaction v2 still uses
`min(stream_max_retries, 2)`.
- Preserved caller-specific behavior around non-retryable errors,
context-window errors, usage-limit errors, and compact-specific final
failure logging.
The shared handler now owns:
- WS -> HTTPS fallback warning emission
- retry delay selection, including server-requested stream retry delay
- retry logging
- first-WebSocket-retry notification suppression
- `Reconnecting... n/max` stream-error notification
- sleeping before the next retry attempt
## Verification
- `cargo test -p codex-core remote_compact_v2`
- `cargo test -p codex-core websocket_fallback`
- `just fix -p codex-core`
Did not run the full workspace test suite.

## Why
The old config-profile mechanism should no longer influence runtime
behavior now that profile selection has moved to file-based `--profile`
config files. Core already rejects a selected legacy `profile = "..."`
with a migration error in
[`core/src/config/mod.rs`](d6451fcb79/codex-rs/core/src/config/mod.rs (L2521-L2529)),
but a few residual consumers still read legacy `[profiles.*]` data while
performing managed-feature checks and personality migration.
That kept dead legacy profile state relevant after selection had been
removed, and could make personality migration depend on a stale or
missing old profile.
## What changed
- Stop scanning legacy `[profiles.*]` feature settings when validating
managed feature requirements.
- Make personality migration consider only top-level `personality` and
`model_provider` settings.
- Remove the now-unused `ConfigToml::get_config_profile` helper.
- Update personality migration coverage to verify that legacy profile
personality fields and missing legacy profile names no longer affect
that migration path.
This keeps the legacy `profile` / `profiles` config shape available for
the remaining compatibility and migration diagnostics; it only removes
these behavior consumers.
## Verification
- Updated `core/tests/suite/personality_migration.rs` for the new
legacy-profile behavior.
- Focused test command: `cargo test -p codex-core
personality_migration`.
## Summary
Change code-mode stored value updates to merge writes by key instead of
replacing the session's complete stored-value map after each cell
completes.
Previously, each cell received a snapshot of stored values and returned
the complete resulting map. When multiple cells ran concurrently, a
later completion could overwrite values written by another cell because
it committed an older snapshot.
This change moves stored-value ownership into `CodeModeService`:
- Each runtime starts from the service's current stored values.
- Runtime completion reports only keys written by that cell.
- The service merges those writes into the current stored-value map on
successful completion.
- Core no longer replaces its stored-value state from a cell result.
As a result, concurrently executing cells can update different stored
keys without clobbering one another.
The move into CodeModeService is motivated by a desire to have this
lifetime tied to a new lifetime object on that side in a subsequent PR.
# Why
`PreToolUse`, `PostToolUse`, and `updatedInput` coverage for local
function tools currently depends on each handler remembering to wire up
the hook contract itself. That makes coverage easy to miss as new
function tools are added, even though most of them share the same basic
shape: a model-facing function call with JSON arguments.
# What
This makes `CoreToolRuntime` provide the default hook contract for
ordinary local function tools:
- build generic `PreToolUse` and `PostToolUse` payloads from the
function tool name and arguments
- apply `updatedInput` rewrites back into function-tool arguments
through the same default path
- let tool outputs override the post-hook input or response when they
have a more stable hook-facing contract
The exceptions stay explicit:
- hosted tools remain outside the generic local function path
- code-mode `wait` and `write_stdin` opt out for now
- `PostToolUse` feedback replaces only the model-visible response, so
code mode keeps its typed tool result
With the generic path in place, the MCP and extension-tool adapters no
longer need their own duplicate pre/post hook plumbing. The new coverage
exercises the registry default plus end-to-end local function behavior
for pre-hook blocking, `updatedInput` rewriting, and post-hook context.
## 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
```

* #23768
* __->__ #23756
## Why
The turn loop no longer needs to decide when a `ModelClientSession`
should reset its websocket state after compaction. That reset behavior
belongs inside the model client, where the websocket cache and retry
state are owned. The repo guidance now calls this out explicitly so
future changes let the incremental request logic decide whether the
previous request can be reused.
## What Changed
- Removed the `reset_client_session` return value from pre-sampling and
auto-compact helpers in `core/src/session/turn.rs`.
- Changed compaction helpers to return `CodexResult<()>` so callers only
handle success or failure.
- Made `ModelClientSession::reset_websocket_session` private to
`core/src/client.rs`, leaving it callable only from model-client
internals.
- Added `AGENTS.md` guidance not to call `reset_client_session`
unnecessarily.
## Validation
- `just test -p codex-core session::turn`
## Why
The idea here is to erase the difference between initial and followup
inputs to a turn. Followup inputs are already represented as TurnInput.
Eventual goal is not to have explicit on task input at all and pull
everything from input Q.
## What Changed
- Changes `SessionTask::run` and the erased `AnySessionTask::run` path
to accept `Vec<TurnInput>`.
- Wraps user-submitted spawn input as `TurnInput::UserInput` at the
session task start boundary.
- Updates `run_turn` to record initial `TurnInput` using the same hook
and recording path used for pending input.
- Keeps review-specific conversion local to `ReviewTask`, where the
sub-Codex one-shot API still expects `Vec<UserInput>`.
- Moves the synthetic compact prompt into `CompactTask` and starts
compact tasks with empty task input.
## Validation
- `cargo check -p codex-core`
- `just test -p codex-core -E
