## Why
`on-request` approval policy text is currently tuned for user-reviewed
approvals. For auto-reviewed productivity runs, likely sandbox blocks
should be escalated earlier so commands that need remote services,
authentication, or other out-of-sandbox access do not first fail or hang
inside the sandbox.
## What changed
- Adds a separate `on_request_auto_review.md` permissions prompt
selected for `AskForApproval::OnRequest` with
`ApprovalsReviewer::AutoReview`.
- Keeps the normal user-reviewed `on-request` wording unchanged.
- Makes the `When to request escalation` bullets more explicit about
likely sandbox blocks, network access, remote
auth/cluster/cloud/database access, out-of-sandbox environment access,
git operations that may write lock files, and short-timeout reruns after
likely sandbox-blocked attempts.
- Omits approved command prefix and `prefix_rule` guidance for the
auto-review on-request prompt.
- Adds prompt tests covering the auto-review path, normal on-request
wording, and inline permission request behavior.
## What
Server should request:
```
{
"id": 42,
"method": "currentTime/read",
"params": {
"threadId": "11111111-1111-1111-1111-aaaaafdc2c11"
}
}
```
Client should respond with something like:
```rust
{
"id": 42,
"result": {
"currentTimeAt": 1781717655
}
}
```
## Why
Sessions configured with `clock_source = "external"` need a
thread-specific external time source before inference. The system clock
remains the default production provider.

## Why
Allows the model to edit files that are hosted on a different OS than
where app-server is running.
## What
* Use `PathUri` for apply_patch-internal data structures
* Limit `PathUri` -> `AbsolutePathBuf` conversion to cases where the
inferred path convention matches the host OS, allows requiring valid
paths to pass to perms check
* Adds `PathConvention::path_segments()` for iterating over path
segments regardless of OS
* Handle cross-platform relative paths in path filename parsing for
sniffing a shell
* Ensure we can apply patches in the wine e2e test
## Why
`built_tools` runs for every sampling request, and local plugin
discovery was repeatedly rereading plugin manifests, skills, MCP
configuration, and app declarations to build the same tool-suggest
metadata.
That source-derived metadata is stable until the existing plugin manager
reloads its cache. Runtime eligibility still needs to reflect the
current install, disable, policy, app-overlap, and authentication state.
## What changed
- Add a bounded, in-memory tool-suggest metadata cache owned by
`PluginsManager`.
- Key cached metadata by plugin identity and source, while applying
authentication routing each time the metadata is projected.
- Invalidate the metadata alongside the existing loaded-plugin cache,
including its normal configuration, marketplace refresh, and
remote-installed-plugin invalidation paths.
- Guard against an in-flight load repopulating stale metadata after
invalidation.
- Keep marketplace membership and all runtime eligibility filtering live
rather than introducing a separate catalog or revision model.
## Impact
Repeated sampling requests reuse already-loaded plugin capability
metadata while retaining the existing plugin-manager lifecycle as the
single freshness boundary.
## Validation
- `just test -p codex-core-plugins` — 252 passed
- Added focused coverage for cache invalidation and authentication
reprojection.
Stacked on #28822.
## Summary
- add a host-injectable current-time provider with a built-in system
implementation
- record UTC developer reminders in history immediately before due model
requests
- keep cadence state per session and force a refresh after compaction
This does NOT include the app server client <-> server clock logic. This
PR is only for the reminder message & system clock that will be used in
prod.
## Testing
- `just test -p codex-core varlatency_`
- `just clippy -p codex-core -p codex-app-server -p codex-mcp-server -p
codex-thread-manager-sample`
- `just fmt`
Make `ListItemsParams::turn_id` optional so callers can list persisted
items across an entire thread or narrow the result to one turn. This
aligns the thread-store API and documentation with thread-wide item
listing while preserving the optional turn-filter behavior for
implementations.
## Stack
Depends on #28746. This PR implements shared rollout-budget accounting
and model-visible reminders using the configuration defined in #28746.
# Description / Main changes to Core:
`AgentControl` will now be the area where "rollout level" features &
accounting will have to live. It is incorrectly named for this
responsibility, but I think it can hold all the necessary shared state &
features (rollout token budget, mutliple thread interruption
responsibilitym etc)
In this PR, we have one "token ledger" that each thread will subtract
from when sampling. The "charge" will occur when response.completed() is
done and the calculation will be done on the responses api usage
carrier. The calculation will weigh sampling and pre-fill tokens as
specified.
Every time the budget crosses the configured reminder threshold, a
developer message is appended before the thread's next request
This remaining budget will _always_ be restated/reminded after a
compaction event.
Expiration and fan-out interruption will be in the stacked follow-up
(and also live in Agent Control).
## Reminders
"You have weighted {session_tokens_left} tokens left in the shared
session token budget."
The first request in each thread context receives the current remainder.
Later reminders are emitted after aggregate weighted usage crosses a
configured interval. If several intervals are crossed before a thread
sends another request, Core inserts one reminder with the latest
remainder.
Compaction response usage is charged before the next context starts. The
next reminder is appended after the compaction summary, leaving the
initial context content stable.
## Tests
Integration coverage verifies:
- weighted output and non-cached input accounting
- initial and periodic reminders
- shared accounting between a root and sub-agent
- post-compaction remainder and message placement
Local checks:
- `just fmt`
- `just test -p codex-core rollout_budget`
- `git diff --check`
The full workspace test suite was not run locally.
## What
Deliver the scripted realtime notification batch after the assistant
text append request instead of after the preceding developer text append
request.
## Why
The batch ends with an upstream error that closes the realtime
conversation. When it is emitted after the developer append, it races
the subsequent assistant append: the app-server RPC can acknowledge the
append before its downstream WebSocket send completes, and the test
intermittently observes three requests instead of four.
Making the fake server wait for the assistant append before emitting the
terminal batch establishes the ordering the test asserts without sleeps
or production-code changes.
## Validation
- `git diff --check`
- CI (the failure is timing-dependent and most reproducible in the
Windows Bazel shard)
## Why
Codex Desktop repairs sandbox-user read/execute access for binaries
copied to `%LOCALAPPDATA%\OpenAI\Codex\bin`, but Computer Use launches
its bundled Node runtime from `%LOCALAPPDATA%\OpenAI\Codex\runtimes`.
On fresh Windows installations, `CodexSandboxUsers` may therefore be
unable to execute the bundled Node binary. The command runner starts,
but `CreateProcessAsUserW` fails with error 5 (`ACCESS_DENIED`), causing
the Node REPL to exit before Computer Use can discover applications.
This is a follow-up to #21564, which added the original runtime `bin`
ACL repair.
## What changed
- Expand the Codex Desktop runtime ACL roots from only `bin` to both
`bin` and `runtimes`.
- Apply the existing inherited read/execute ACL repair to each runtime
directory when it exists.
- Rename the setup helper to reflect that it now handles multiple
runtime paths.
## Validation
- `cargo fmt -- --check`
- `just test -p codex-windows-sandbox` was run: 113 tests passed and
five environment-dependent legacy execution tests failed because
`CreateRestrictedToken` returned error 87.
## Summary
- Initialize stderr tracing and the configured OpenTelemetry provider
for local and remote `codex exec-server` startup.
- Instrument the local and remote server entrypoints with a root runtime
span.
- Keep raw Noise environment, registration, and stream identifiers out
of exported spans while preserving them in local debug events.
- Keep telemetry setup in a focused CLI module instead of growing the
top-level command entrypoint.

Fixes#28263.
## Why
When a thread starts with `/goal`, the goal extension can update SQLite
goal state before the thread has any user-turn rollout items.
`thread/list` and `thread/search` rely on persisted listing metadata, so
a goal-first live thread could be absent from app-server listings after
restart even though the goal itself existed.
This regressed when goal handling moved out of core: the core path wrote
the goal update through the live thread rollout path, while the
extension-backed app-server path only updated goal state and emitted the
live notification.
## What
- Add `GoalSetOutcome::thread_goal_updated_item()` so the goal extension
owns the canonical `ThreadGoalUpdated` rollout item shape.
- Expose a narrow `CodexThread::append_rollout_items()` helper that
appends through the live thread and keeps derived SQLite metadata in
sync.
- When app-server sets a goal on an active live thread, persist the goal
update through that live-thread path.
- Add an app-server regression test that starts a live thread with
`thread/goal/set` and verifies it appears in state-DB-only
`thread/list`.
## Verification
- `env -u CODEX_SQLITE_HOME just test -p codex-app-server
goal_first_live_thread_appears_in_state_db_thread_list`
## Summary
- keep context injection on a single ContextContributor trait
- split context injection into thread-scoped and turn-scoped
contribution methods
- wire turn-scoped fragments into initial context assembly so extensions
can contribute context from turn-local state
Scope MCP sandbox metadata to the MCP server's owning environment.
Previously, `codex/sandbox-state-meta` always used the turn's primary
cwd and rebuilt a legacy sandbox policy from that cwd. That can be wrong
for MCP servers owned by a different execution environment.
This now sends the owning environment cwd as a `file:` URI in
`sandboxCwd`, keeps `permissionProfile` as the permission source of
truth, and omits sandbox-state metadata when a non-default server
environment is not selected for the turn. Local/default MCP servers keep
the existing fallback cwd behavior.

- `just fmt`
- `just bazel-lock-update`
- `just bazel-lock-check`
- `just test -p codex-mcp`
- `just test -p codex-core mcp_sandbox_cwd`
- `cargo build -p codex-rmcp-client --bin test_stdio_server`
- `just test -p codex-core

## What
Run the Windows argument-comment-lint job on the `windows-2022` hosted
runner instead of the custom Windows runner pool.
## Why
The custom pool recently moved from the Visual Studio 2022 Windows image
to `windows-2025-vs2026`. Since that migration, the job fails while
Bazel materializes LLVM external repository sources, before the argument
lint itself runs. The same failure appears across unrelated PRs.
This narrow change tests GitHub’s recommended mitigation for workloads
that still require the Visual Studio 2022 image:
https://github.com/actions/runner-images/issues/14017
## How
Use the standard `windows-2022` runner for only the Windows
argument-comment-lint matrix entry. No product code or lint behavior
changes.
## Summary
Remote stdio MCP servers send tool calls by writing JSON-RPC bytes
through `process/write`.
When the exec-server websocket drops at the wrong time, the remote
process can survive session recovery, but the stdin write can still fail
back to RMCP as a transport send error. RMCP then closes the stdio MCP
transport, so tools like `node_repl` are lost even though the
process/session recovery path is working.
This changes `process/write` to be safe to retry across exec-server
recovery:
- adds a required `writeId` to `process/write`
- retries remote `Session::write` with the same `writeId` after
reconnect
- remembers accepted write ids per process so duplicate retries return
`Accepted` without writing the same bytes to child stdin again
- covers both the client retry path and server-side write id dedupe with
tests
In simple terms:
```text
before:
write to MCP stdin -> websocket closes -> write errors -> RMCP closes node_repl
after:
write to MCP stdin -> websocket closes -> reconnect -> retry same writeId
server either writes once or recognizes it already did
```
Fixes#28104.
## Summary
Active `/goal` turns should leave the persisted goal paused whenever the
TUI interrupts the running turn. The bug in #28104 showed this most
visibly through `Esc`: some interrupt paths aborted the turn without
updating the goal status, so the goal could remain active and continue
automatically.
This change makes `ChatWidget` pause an active goal before the TUI sends
an interrupt from the status-row path, the pending-steer path, `Ctrl+C`,
or a request-user-input overlay. The modal overlay now reports whether a
key will interrupt the turn, which keeps modal `Esc` and `Ctrl+C`
behavior aligned with the normal interrupt paths.
## Manual Testing
Built the local CLI with `just codex --help`, then launched the local
TUI with goals enabled. Started an active `/goal` turn and interrupted
it with `Esc`, then resumed and repeated with `Ctrl+C`; both paths
showed `Goal paused`, the interrupted-conversation message, and the
`Goal paused (/goal resume)` footer. I also stopped the background
terminal and exited the TUI cleanly after the run.
I did not find a reliable standalone manual path to force the
request-user-input overlay case, so that path is covered by the focused
automated test.
