## Context
Inline compaction is part of the active logical turn. Compact requests
and the sampling requests around them should use the same turn state,
including when compaction is the first request to establish it.
## Change
Pass the turn-scoped `OnceLock` directly to inline v1 compaction so
`/responses/compact` includes an established value in the existing HTTP
header. Capture `x-codex-turn-state` from the compact response into that
same lock, allowing pre-turn compact to establish the value that
subsequent sampling reuses.
V2 compact already uses the normal Responses HTTP/WebSocket path and
continues to share the same `OnceLock` without separate plumbing. The
first returned value wins for the logical turn.
## Test plan
Integration coverage verifies that:
- pre-turn v1 compact can establish state for the first sampling request
- inline v1 compact receives established state over HTTP
- inline v2 compact reuses established state over HTTP
- inline v2 compact reuses established state over WebSocket
CI validates the full change.
## Context
Turn state is scoped to one logical turn, but the WebSocket path
currently exchanges it through upgrade headers, which are scoped to the
physical connection. A connection may be reused across turns, so its
handshake cannot represent the turn lifecycle reliably.
## Change
Exchange turn state on each WebSocket response request instead:
- send an established value in `response.create.client_metadata`
- read the returned value from the existing `response.metadata` event
- retain the first value in the turn-scoped `ModelClientSession`
`OnceLock`
- start the next logical turn without state, even when it reuses the
same WebSocket connection
This gives WebSocket requests the same first-value-wins contract as the
existing HTTP path.
## Test plan
Integration coverage verifies that:
- WebSocket replays returned state on same-turn follow-ups
- later response metadata does not replace the first value
- state resets at the logical turn boundary without requiring a
reconnect
CI validates the full change.
## Stack
This is 1/2. #28002 builds on this request-scoped transport to carry
established state through compact requests.
## Why
We want to make it possible for an app-server orchestrator on one OS to
control an exec-server on another host running a different OS. In
practice this kinda already works if you get lucky and the two hosts
have the same path format, but we mangle quite a lot of operations if
either end is Windows.
This test starts exercising that interaction, although right now the
initial bootstrap fails. Future changes will expand the test's
assertions to match improved support.
## What
Stacked on #27964. This adds a small Windows exec-server fixture and a
Linux protocol smoke test using the reusable Wine harness, covering
Windows environment discovery, non-TTY `cmd.exe` execution, output, exit
status, and working directory.
Once we've got the full codex binary cross-building under Bazel we could
consider moving to the real binary instead of the stripped down
exec-server-only binary used here.
## Why
Managed deployments need a reliable deny gate for remote control.
Persisted enablement and explicit startup requests currently remain able
to start the transport, while the removed `features.remote_control` key
is intentionally only a compatibility no-op.
This adds a dedicated requirement that administrators can use to force
remote control off without deleting the user's persisted preference.
Removing the requirement and restarting restores the prior choice.
## What Changed
- Added top-level `allow_remote_control` requirements parsing, sourced
layer precedence, debug output, and `configRequirements/read` exposure
as `allowRemoteControl`.
- Added a typed transport policy captured from the startup requirements
snapshot. Managed disable forces the initial state to disabled and
prevents enrollment, refresh, connection, and persisted-preference
mutation.
- Rejected every `remoteControl/*` RPC before parameter deserialization
with JSON-RPC `-32600` and `remote control is disabled by managed
requirements`.
- Preserved the existing disabled status notification and the previous
behavior when the requirement is `true` or omitted.
- Regenerated app-server protocol schemas and documented the new
requirement.
## Verification
- Confirmed all remote-control RPCs, including a malformed request,
return the managed-policy error while the initial status notification
remains `disabled`.
- Confirmed explicit ephemeral startup and persisted enablement make no
backend connection and leave the SQLite preference unchanged.
- Confirmed `allow_remote_control = true` does not enable or block
remote control and `configRequirements/read` returns
`allowRemoteControl: false` for the deny policy.
Related issue: N/A (managed-policy hardening).
## Context
Some plugins expose both Apps and MCP servers. This PR moves auth-aware
surface projection into `core-plugins::PluginsManager`, so callers get a
consistent effective plugin view. Later PRs narrow the conflict rule and
update listing/install paths.
The high level goal of this PR is to set up the plumbing to
conditionally filter App/MCP in the plugin manager layer. We start by
removing MCP servers when using SIWC/Codex-backend auth, and removing
Apps when using API-key-style auth.
This PR is now stacked on #27652, which contains only the constructor
plumbing for seeding `PluginsManager` with the current auth mode.
## Stack
- PR1: #27652 seed plugin manager auth at construction.
- PR2: #27459 route plugin surfaces by auth mode.
- PR3: #27607 dedupe plugin MCP servers by App declaration name.
- PR4: #27602 preserve plugin Apps in connector listings.
- PR5: #27461 skip install-time plugin MCP OAuth for matching App
routes.
## Summary
- API-key/non-ChatGPT routes hide plugin Apps and keep plugin MCPs.
- ChatGPT/SIWC with Apps enabled keeps plugin Apps and suppresses MCPs
for dual-surface plugins.
- MCP-only plugins stay available for ChatGPT/SIWC sessions.
- Cached plugin load outcomes are re-projected when auth mode changes.

## Why
We want to make it possible for an app-server orchestrator on one OS to
control an exec-server on another host running a different OS. In
practice this kinda already works if you get lucky and the two hosts
have the same path format, but we mangle quite a lot of operations if
either end is Windows.
We should be able to test the cross-platform interactions for
exec-server, but we want to do this fairly soon and need a lightweight
option for testing. Using Wine to run the Windows side is far from
perfect, but it should give us a decent measure of how well we're
handling the basics of paths, process spawning, shell interaction, etc.
Future changes will add actual exec-server tests and possibly extensions
to the Wine testing environment.
## What
To make the cross-target-triple build easy, these tests are added only
to the Bazel build. This change adds an x86_64 Wine prebuilt managed by
Bazel and some build rules that can set up the needed toolchain
transition.
The support library for running Wine in a test environment created by
the Bazel rules comes with its own basic unit and integration tests.
Their primary priority is to make sure we don't leak child processes on
developer machines and that we can build and launch a basic hello world
binary.
## Validation
Confirmed these new tests are running on the [x86_64 bazel ubuntu

## Context
Plugins can expose more than one way for Codex to use them: App
connectors for ChatGPT/SIWC-backed sessions and MCP servers for API key
login sessions. The broader goal is to make `PluginsManager` the place
that understands which plugin surfaces should be visible for the current
auth route, so callers do not each have to make that decision
themselves.
This PR is the small setup step for that work. It lets the plugin
manager be created with the current `AuthMode`, which gives the followup
auth routing PRs the information they need without relying on setter
injection.
## Stack
- PR1: #27652 seed plugin manager auth at construction.
- PR2: #27459 route plugin surfaces by auth mode.
- PR3: #27607 dedupe plugin MCP servers by App declaration name.
- PR4: #27602 preserve plugin Apps in connector listings.
- PR5: #27461 skip install-time plugin MCP OAuth for matching App

## Summary
- Let `PluginsManager::new_with_restriction_product` accept an initial
`AuthMode`.
- Keep `PluginsManager::new` behavior unchanged for ordinary callers.

## Summary
- Keep local plugin suggestions bounded to fallback and explicitly
configured plugins.
- Preserve app-overlap recommendations for remote plugins using cached
catalog metadata.
- Remove the WSL-specific local discovery exception and move
manager-owned discovery tests into `codex-core-plugins`.
## Why
Local curated marketplaces were allowlisted before plugin detail
loading, so every uninstalled candidate could be deep-read before its
app IDs were checked. That caused per-turn reads of candidate plugin
manifests, skills, app configs, hooks, and MCP configs, which is
especially expensive on slow disks.
Remote discovery does not need those local candidate reads because app
IDs are already available in the cached remote catalog. Installed local
plugins are still loaded when needed to determine the user's installed
app IDs.

## Why
[#25345](https://github.com/openai/codex/pull/25345) was approved,
green, and squash-merged into its stacked base branch,
`fcoury/tokenmaxxing-api`. Four minutes later, that base branch was
force-pushed back to an API-only rebased head while preparing
[#25344](https://github.com/openai/codex/pull/25344) for `main`. As a
result, the squash commit from #25345 was orphaned and the TUI command
never reached `main` or a release.
This PR relands the orphaned TUI change from
[`411410b8`](https://github.com/openai/codex/commit/411410b85c2d8eb050d441f17396c5c4048d866f)
on current `main`.
## What changed
- Add `/usage`, `/usage daily`, `/usage weekly`, and `/usage cumulative`
for account token activity.
- Fetch account usage asynchronously through the existing
`account/usage/read` app-server RPC.
- Render daily, weekly, and cumulative activity with theme-aware
terminal palettes and bounded transient cards.
- Preserve transcript ordering while assistant streams, history
consolidations, active cells, and hooks complete.
- Hide `/usage` from completion when backend auth is unavailable while
keeping typed-command guidance.
- Carry current-main behavior forward for cwd-aware Markdown parsing,
Windows Terminal color detection, and personal access token auth.
- Clear pending usage cards on thread rollback and delay completed cards
until live hook output is committed.
- Add focused regression and snapshot coverage for loading, auth errors,
invalid views, rollback, hook ordering, layout, and charts.
## Prior review
The original implementation was approved by Eric Traut in #25345 after
testing multiple themes and light/dark terminals. This PR preserves that
reviewed implementation while adapting it to current `main` and adding
regression coverage for newer rollback and hook lifecycle behavior.

- Focused rollback, hook-ordering, and error snapshot tests — 4 passed.
- `just fix -p codex-tui` — passed.
- `UV_CACHE_DIR=/private/tmp/codex-uv-cache just fmt` — passed.

-

- `just argument-comment-lint` could not complete because the local
Bazel LLVM `compiler-rt` repository is missing `include/sanitizer/*.h`.
The touched Rust diff was manually inspected and no missing
opaque-literal argument comments were found.
## Stack
1. [1 of 3] Support long raw TUI goal objectives - #27508
2. [2 of 3] Support long pasted text in TUI goals - #27509
3. **[3 of 3] Support images in TUI goals** - this PR
## Why
The first two PRs make goal definitions resilient to long text, but
`/goal` still dropped image inputs from the composer. That meant a user
could attach images while defining a goal and the resulting goal
continuation would not have any useful reference to those images.
Goal state still persists only objective text, so image inputs need to
become paths or URLs that the agent can read later.
## What Changed
- Extends TUI `GoalDraft` with local image attachments and remote image
URLs.
- Copies local goal images through the app-server filesystem layer into
the managed goal attachment directory, then rewrites active image
placeholders to file references.
- Appends unplaced local images and remote image URLs to the objective
as referenced image files or URLs.
- Preserves goal image metadata through live `/goal` submission and
queued `/goal` dispatch.
## Verification
- Added goal materialization coverage for local image files and remote
image URLs.
- Added/updated TUI slash-command coverage showing `/goal` drafts
include attached images instead of dropping them.
## Manual Testing
- Attached an image by bracketed-pasting its local path into a live
`/goal` composer. The `[Image #1]` placeholder became a server-host
`image-1.png` reference, copied bytes matched exactly, and no attachment
was written under the TUI's local home.
- Deleted an image placeholder before submitting a small goal and
verified no image was copied.
- Attached PNG and JPEG files to the same goal. Placeholder order was
preserved as `image-1.png` and `image-2.jpg`, and both remote copies
matched their source bytes.
- Tried extensionless, malformed-extension, and
extension/content-mismatched paths; the composer rejected them as image
attachments before goal dispatch rather than creating misleading managed
image files.
- Combined a local image, a large pasted block, and enough raw text to
exceed 4,000 characters. The remote attachment directory contained the
image, paste sidecar, and `goal-objective.md`; all embedded references
used server-host paths and both payloads matched their sources.
- Submitted an image replacement while a goal was active, verified no
image was copied before confirmation, then canceled and confirmed the
attachment count was unchanged.
## Why
We have some large gaps in our thread start, resume, and pre-sampling
traces that make it hard to tell where latency is coming from.
## What Changed
- Added coarse spans around thread start/resume, turn context
construction, rollout reconstruction, skill/plugin loading, and tool
preparation.
- Added a breakdown of discoverable-tool preparation across connector
loading, plugin discovery, and local plugin details.
## Testing
- `cargo check -p codex-app-server -p codex-core -p codex-core-skills -p
codex-core-plugins`
- Built the app-server locally and exercised thread start, first turn,
follow-up turn, server restart, thread resume, and a resumed turn.
In the release job from
https://github.com/openai/codex/actions/runs/27391514823
staging the nine npm release tarballs serially took 104 seconds.
Each package build writes to a separate staging directory, output path,
and npm cache. Run them through the script's existing thread pool,
bounded by the available CPU count. Delete each staging tree as its
build finishes so concurrency does not retain all copies until the end.
On ubuntu-24.04 in
https://github.com/openai/codex/actions/runs/27397232050
two serial trials took 103 and 101 seconds, while concurrent trials
both took 41 seconds. Comparing every extracted file from the first
serial and concurrent sets found no differences. This removes about one
minute from every release.
In the Windows x64 packaging job from
https://github.com/openai/codex/actions/runs/27391514823
building the primary and app-server package archives serially took 116
seconds.
Both archives read the same signed-binary directory but write separate
package trees and output files. Run them concurrently with xargs -P2.
The package helper rewrites DotSlash executables under the process temp
directory. A naive concurrent run failed when one process tried to
replace an executable used by the other. Give each bundle separate TMP
and TEMP roots to keep those caches independent.
On Windows x64 in
https://github.com/openai/codex/actions/runs/27397197944
three serial trials took 127, 128, and 126 seconds. Concurrent trials
took 76, 74, and 74 seconds, saving 52 to 54 seconds. This removes about
50 seconds from the release critical path without changing the packaging
commands or output set.
## Why
`PathUri::from_abs_path` can fail for absolute paths that do not have a
normal `file:` URI representation, forcing filesystem call sites to
handle a conversion error even though the original path can be preserved
losslessly.
## What
Make `from_abs_path` infallible and migrate its callers. Unrepresentable
paths use `file:///%00/bad/path/<base64>`, encoding Unix bytes or
Windows UTF-16LE; `to_abs_path` validates and decodes that fallback. The
leading encoded null reserves a namespace that cannot collide with a
real Unix or Windows path, and fallback URIs remain opaque to lexical
path operations.
## Validation
Added path-URI coverage for Unix null and non-UTF-8 paths, Windows
device/verbatim and non-Unicode paths, serialization, malformed
fallbacks, opaque lexical operations, invalid native payloads, and
literal `/bad/path` collision resistance.
In the x64 packaging job from
https://github.com/openai/codex/actions/runs/27391514823
archiving and uploading PDBs took 65 seconds after signing. Release
packaging could not start until that work completed.
Windows code signing changes executables but not their PDBs. Package
the PDBs in a sibling Ubuntu job as soon as all binary artifacts are
available. Signing and release packaging can then proceed without
waiting for the symbols archive, reducing the critical path by about
one minute.
## Why
The paired thread-environment migration changed several generic test
turn helpers from supplying a fallback cwd to explicitly selecting the
local environment. That changes their meaning under
`build_with_remote_env()`: remote-only fixtures cannot resolve the
forced local selection, so the tests fail before exercising apply-patch,
RMCP, unified-exec, or view-image behavior.
Generic helpers should inherit the environment selected by their
fixture. Tests that intentionally exercise local routing continue to
select the local environment explicitly.
## What changed
- Remove forced `local_selections(...)` overrides from the generic
apply-patch, RMCP, unified-exec, and view-image turn helpers.
- Remove the imports made unused by those deletions.
## Testing
- Not run locally; this is a test-fixture-only change and the `full-ci`
branch will exercise the affected remote shards.
## Summary
This PR promotes Mentions 2.0 (unified TUI mention popup) to stable and
enables it by default.
- Keep `mentions_v2` as a temporary rollback path to the legacy split
popups (`--disable mentions_v2`).
- Add feature-default and snapshot coverage for the default experience.

## Test plan
- Launch Codex without any feature overrides.
- Type `@` in the TUI composer.
- Confirm the unified mentions menu opens and displays filesystem,
plugin, and skill results.
Each Windows packaging job creates three compressed forms of five
binaries in sequence. This takes roughly two minutes and is on the
release critical path.
Use two xargs workers to compress independent binaries concurrently.
The workers only read the raw executables and write per-binary archive
names. The Codex zip can safely read the helper executables while their
own archives are generated.
On a 16-vCPU AMD EPYC 9V74 Windows x64 release runner, alternating
trials against artifacts from release run 27391514823 measured:
serial: 121 s, 123 s, 121 s
parallel: 73 s, 73 s, 74 s
This saves 47 to 50 seconds in the x64 packaging lane, reducing the
observed release critical path by about 48 seconds when x64 remains the
limiting lane.
https://github.com/openai/codex/actions/runs/27401905938
Codex seems to do interesting things with `cfg`'s sometimes and it seems
it would be good to give it guidance about how broadly our Rust needs to
work.
This adds a very brief section to AGENTS.md explaining that we target
the major desktop OSes and that we want the vast majority of our logic
to be portable across them.
## Why
We need request-level evidence for Guardian cases where
`codex-auto-review` is missing from the client-side model catalog and
the review falls back to the parent model.
## What changed
- Add `guardian_catalog_contains_auto_review` to Guardian Responses API
client metadata.
- Add `guardian_model_provider_id` to Guardian Responses API client
metadata.
- Keep review-session metadata optional so callers without metadata
preserve the existing `None` path.
- Add tests for override, normal preferred-model, and
missing-auto-review-catalog behavior.

## Stack
1. [1 of 3] Support long raw TUI goal objectives - #27508
2. **[2 of 3] Support long pasted text in TUI goals** - this PR
3. [3 of 3] Support images in TUI goals - #27510
## Why
Large text pasted into the TUI composer is represented as a paste
placeholder plus pending paste metadata. For `/goal`, preserving only
the visible placeholder is not enough: the agent would see a short
placeholder string instead of the actual pasted text, and the long-text
support from the first PR would never see the payload.
The TUI also needs to avoid writing stale sidecar files when a user
pastes a large block and then deletes its placeholder before submitting
the goal.
## What Changed
- Introduces a TUI `GoalDraft` for goal submissions so `/goal`, `/goal
edit`, and queued goal commands can carry objective text plus text
elements and pending paste payloads.
- Materializes active pasted-text placeholders to `pasted-text-N.txt`
files through the app-server filesystem path introduced in #27508.
- Rewrites active paste placeholders in the persisted objective to file
references, while leaving literal placeholder-looking text alone.
- Filters out deleted paste placeholders so otherwise-small goals do not
require `$CODEX_HOME` or remote filesystem writes.
- Preserves pending paste metadata when a `/goal` command is queued
before a thread exists.
## Verification
- Added goal materialization tests for active paste placeholders,
deleted paste placeholders, and whitespace-only paste payloads.
- Added/updated TUI slash-command tests for large pasted text, queued
`/goal` commands before thread start, and queued oversized goal
behavior.
## Manual Testing
- Used real terminal bracketed-paste sequences through a remote TUI
session. A 1,228-byte multiline paste became `pasted-text-1.txt`; its
first/last lines and byte count matched exactly, and the persisted
objective referenced the server-host path.
- Pasted a large block, deleted its placeholder, and submitted a small
replacement objective. No new directory or sidecar file was created.
- Added two same-length large pastes to one goal. The composer
disambiguated their visible placeholders, and materialization preserved
order and contents in `pasted-text-1.txt` and `pasted-text-2.txt`.
- Submitted a whitespace-only large paste and verified the goal was
rejected as empty without writing a file.
- Submitted a pasted-text replacement while another goal was active,
verified no file was written before confirmation, then canceled and
confirmed the original goal remained unchanged.
- Combined a large paste with enough raw text to exceed 4,000 characters
after placeholder rewriting. The paste sidecar and `goal-objective.md`
were created in the same remote attachment directory, and `/goal edit`
restored the rewritten objective with its sidecar reference.
## Summary
Add an explicit `user` or `developer` role to
`thread/realtime/appendText` and propagate it through the realtime input
queue into `conversation.item.create`. Older JSON clients that omit the
field continue to default to `user`.
This lets app-provided context such as memory retain developer authority
without bypassing app-server through a renderer-owned data channel. The
app-server schemas, API documentation, and focused protocol and
websocket coverage are updated with the new contract.
The Codex Apps consumer is tracked in
[openai/openai#1025261](https://github.com/openai/openai/pull/1025261).

## Summary
Startup warnings for under-development features only recognized bare
boolean toggles like `features.foo = true`. An upcoming feature will use
table-format config, so `features.foo = { enabled = true, ... }` needs
to count as an explicit opt-in too.
This updates the warning predicate to recognize structured tables with
`enabled = true`, while leaving tables without that field unwarned.
## Testing
- `just fmt`
- `just test -p codex-features
unstable_warning_event_mentions_enabled_structured_under_development_feature`
## Why
Windows Credential Manager limits generic credential blobs to 2,560
bytes. Large serialized ChatGPT auth payloads can exceed that limit, so
keyring-mode CLI auth needs a backend that keeps only the encryption key
in the OS keyring and stores the payload in Codex's encrypted
local-secrets file.
This is the third PR in the encrypted-auth stack:
1. #27504 — feature and config selection
2. #27535 — auth-specific local-secrets namespaces
3. This PR — CLI auth implementation and activation
4. MCP OAuth implementation and activation
## What Changed
- Added encrypted CLI-auth storage using the `CliAuth` secrets
namespace.
- Preserved direct keyring storage for platforms/configurations where it
remains selected.
- Selected the backend consistently for login, logout, refresh,
device-code login, auth loading, and login restrictions.
- Threaded resolved bootstrap/full config through CLI, exec, TUI,
app-server account handling, cloud config, and cloud tasks.
- Removed stale `auth.json` fallback data after successful encrypted
saves and removed encrypted, direct-keyring, and fallback data during
logout.
- Added storage and integration coverage for both direct and encrypted
keyring modes.
MCP OAuth persistence is intentionally left to the next PR.

## Why
Removes the realtime audio support from TUI.
## What Changed
- Removed the TUI `/realtime` and realtime `/settings` command paths.
- Deleted TUI voice capture/playback, WebRTC session handling,
audio-device selection UI, and recording-meter code.
- Removed TUI realtime tests and snapshots that covered the deleted
surfaces.
- Dropped the TUI-only `cpal` and `codex-realtime-webrtc` dependencies
and refreshed the Rust/Bazel locks.
## Why
Multi-agent v2 `send_message` deliveries already reach the receiving
model as typed `agent_message` items with encrypted content.
Child-completion notifications are generated by Codex itself, so their
content is plaintext and previously fell back to a serialized JSON
envelope inside an assistant message.
With plaintext `input_text` supported for `agent_message`, both delivery
paths can use the same model-visible type while preserving explicit
author and recipient metadata.
## What changed
- add plaintext `input_text` support to `AgentMessageInputContent` and
regenerate the affected app-server schemas
- preserve `InterAgentCommunication` as structured mailbox input instead
of converting it to assistant text
- record delivered communications as typed `agent_message` history items
- persist a dedicated rollout item so local delivery metadata such as
`trigger_turn` remains available without leaking into the Responses
request
- reconstruct typed agent messages on resume and preserve fork-turn
truncation behavior
- remove request-time assistant-content parsing
- preserve plaintext and encrypted inter-agent deliveries in stage-one
memory inputs
- normalize and link plaintext and encrypted agent messages in rollout
traces without treating inbound messages as child results
- cover the real MultiAgent V2 child-completion path end to end with
deterministic mailbox synchronization

## Summary
Removes Plugin descriptions from the dev message, since descriptions of
skills and MCPs cover the capabilities offered by the plugin.
## Testing
- [x] Updates unit tests
## Summary
- reuse the shared shell read parser for implicit skill doc invocation
detection
- add regression coverage for `nl -ba .../SKILL.md`
## Why
Desktop could render `Read User Context skill` for reads recognized by
the shared command parser, while implicit `skill_invocation` analytics
used a separate reader allowlist and missed cases such as `nl`.
## Validation

PATH=/Users/alexsong/.cache/cargo-home/bin:$PATH
CARGO_HOME=/Users/alexsong/.cache/cargo-home just test -p
codex-core-skills`
- `git diff --cached --check`
- `just fmt` attempted; Rust formatting completed, but the Python
formatters could not download uncached Ruff wheels because
`files.pythonhosted.org` is blocked in this sandbox.
- `bazel mod deps --lockfile_mode=update/error
--repo_env=ASPECT_TOOLS_TELEMETRY= --repo_env=DO_NOT_TRACK=1` evaluated
the module graph and produced no `MODULE.bazel.lock` diff, but Bazel
crashed on sandboxed `sysctl` during exit.
## Why
Review guidance should explicitly discourage widening crate APIs for
testing convenience. Keeping those boundaries narrow reduces accidental
coupling and prevents one-off test utilities from becoming durable
public surface area.
## What
- Add a crate API surface rule to `AGENTS.md`.
- Ask reviewers to keep crate APIs small and avoid proliferating
test-only helpers.
## Test plan
- Not run (documentation-only change).
## Why
CLI auth and MCP OAuth credentials should use separate encrypted files
while sharing the existing local-secrets implementation and
OS-keyring-backed encryption key mechanism.
This is the second PR in the encrypted-auth stack:
1. #27504 — feature and config selection
2. This PR — auth-specific local-secrets namespaces
3. CLI auth implementation and activation
4. MCP OAuth implementation and activation
## What Changed
- Added `LocalSecretsNamespace` variants for shared secrets, CLI auth,
and MCP OAuth.
- Selected `local.age`, `cli_auth.age`, or `mcp_oauth.age` from the
namespace.
- Made atomic temporary filenames derive from the selected secrets
filename.
- Added namespaced `SecretsManager` construction and coverage proving
the auth namespaces write separate encrypted files.
- Made the default keyring store clonable for downstream namespaced auth
backends.
This PR does not activate either auth backend or change existing
credential behavior.
## Validation
- `just test -p codex-secrets` — 7 passed
- `just test -p codex-keyring-store` — package has no test binaries
- `just fmt`
## Why
`codex login` previously persisted newly issued OAuth credentials and
only then attempted to revoke the superseded refresh token. The old
credential must be revoked before a replacement browser or device-code
flow starts, and successful login must not perform any post-login
revocation attempt.
## What changed
- Revoke and clear existing stored auth before browser or device-code
CLI login begins.
- Remove superseded-token detection and revocation from the shared token
persistence path; successful login now only saves the new credentials.
- Read the raw configured auth store during CLI cleanup so
environment-provided auth cannot mask the stored refresh token.
- Preserve `auto` storage fallback semantics when keyring deletion fails
by clearing the fallback auth file.
- Add a process-level CLI regression test that requires the revoke
request to precede every device-login request and occur exactly once.
If replacement login is canceled or fails, the previous local
credentials have already been cleared. Remote revocation remains best
effort, matching explicit logout behavior.
## Validation
### Process-level before/after reproduction
I compiled the real `codex` CLI from the pre-fix parent (`14df0e8833`)
and from the PR implementation (`25c002f23b`; the login behavior is
unchanged at the current head), then ran the same device-code flow
against a local HTTP mock OAuth authority.
Each run:
1. Used a fresh temporary `CODEX_HOME` configured with
`cli_auth_credentials_store = "file"`.
2. Seeded that temporary home with managed ChatGPT auth containing
`old-access` and `old-refresh` tokens.
3. Pointed `CODEX_REVOKE_TOKEN_URL_OVERRIDE` at the mock `/oauth/revoke`
endpoint.
4. Ran the compiled CLI as:
```shell
CODEX_HOME=<temporary-home> \
CODEX_REVOKE_TOKEN_URL_OVERRIDE=<mock-issuer>/oauth/revoke \
<compiled-codex> login --device-auth --experimental_issuer <mock-issuer>
```
5. Recorded every request received by the mock authority. The mock
marked `new-access` valid when `/oauth/token` issued it and invalidated
it if `/oauth/revoke` arrived afterward, reproducing the observed
session-invalidating failure mode. After login exited, the harness also
verified the persisted refresh token and probed a protected endpoint
with `new-access`.
| Build | Observed request order | CLI/persistence result | `new-access`
probe |
| --- | --- | --- | --- |
| Pre-fix | `usercode → device token → OAuth token →
revoke(old-refresh)` | Exit `0`; `new-refresh` persisted | `401` |
| PR | `revoke(old-refresh) → usercode → device token → OAuth token` |
Exit `0`; `new-refresh` persisted | `200` |
The PR run therefore issued exactly one revocation request, before any
request that initiated the replacement login, and issued no revocation
after token exchange.
### Regression coverage
`codex-rs/cli/tests/login.rs::device_login_revokes_existing_auth_before_requesting_new_tokens`
runs the real first-party `codex` binary against a `wiremock` OAuth
server with an isolated temporary `CODEX_HOME`. It asserts:
- the exact request sequence is `/oauth/revoke`,
`/api/accounts/deviceauth/usercode`, `/api/accounts/deviceauth/token`,
then `/oauth/token`;
- there is exactly one revoke request and its body contains
`old-refresh` with the `refresh_token` hint;
- the completed login persists `new-refresh`.
Local validation:
- `just test -p codex-login` — 130 passed
- `just test -p codex-cli` — 280 passed, including the new process-level
regression test
- `just bazel-lock-check`
## Why
Windows Credential Manager limits generic credential blobs to 2,560
bytes. The encrypted local secrets backend avoids storing large
serialized auth payloads directly in the OS keyring, but selecting that
backend needs an independently reviewable feature/config layer before
the auth and secrets implementation is wired in.
## What Changed
- Added the stable `secret_auth_storage` feature, enabled by default on
Windows and disabled by default elsewhere.
- Added `AuthKeyringBackendKind` and config resolution for full and
bootstrap config loading.
- Applied managed feature requirements when resolving the bootstrap auth
backend.
- Updated the generated config schema and added focused tests.
This is the base PR for #17931. The auth, secrets, MCP, CLI, TUI, and
app-server implementation remains in that follow-up PR.
## Validation
- `just test -p codex-features`
- `just test -p codex-config`
- `just test -p codex-core
resolve_bootstrap_auth_keyring_backend_kind_uses_secret_auth_storage_feature`
- `just write-config-schema`
- `just fix -p codex-core`
The full `just test -p codex-core` run compiled successfully and ran
2,690 tests; 2,589 passed, one was flaky, and 101 environment-sensitive
tests failed because this shell injects a `pyenv` rehash warning into
command output or because sandboxed subprocesses timed out.
## Why
`ExecutorFileSystem::get_metadata` reports file kind and timestamps but
not size. Internal callers that need to enforce a size limit therefore
have to read the complete file first, which is especially wasteful for
remote filesystems.
This adds the missing internal metadata so consumers can reject
oversized files before transferring or buffering them. The field is
named `size`, matching VS Code's `FileStat.size` filesystem convention.
## What changed
- add `size: u64` to internal `FileMetadata`
- populate it from the underlying filesystem metadata
- carry it through sandbox-helper and remote exec-server responses
- cover files, directories, symlink targets, and sandboxed reads across
local and remote filesystem implementations
The new field is intentionally not exposed through the app-server API.
## Testing
- `just test -p codex-exec-server get_metadata`
- `just test -p codex-exec-server
file_system_sandboxed_metadata_and_read_allow_readable_root`
- `just test -p codex-core-plugins`
- `just test -p codex-skills-extension`
## Why
Standalone image generation emitted a started item but no terminal item
when the backend failed. Clients could leave the operation unresolved or
render it as successful.
## What changed
- Emit a terminal image-generation item with `status: "failed"` when
generation or editing fails.
- Skip image persistence for failed terminal items.
- Render failed image generation distinctly in TUI history.
- Preserve the status when handling live and replayed terminal items.
## Looks for TUI, App-Side change needed

## Validation
- `just test -p codex-image-generation-extension`
- App-server image-generation tests
- Core stream-event tests
- TUI image-generation lifecycle and snapshot tests
- Scoped Clippy and formatting
## Why
`apply_patch` maintained separate batch and streaming parsers for the
same patch grammar. That duplicated the parsing rules and allowed final
execution to disagree with the live streamed preview.
## What changed
- Make `StreamingPatchParser` the single owner of hunk and environment
ID parsing.
- Keep heredoc and outer patch-boundary normalization in the existing
`parse_patch` wrapper, preserving its public API.
- Reject non-whitespace content after `*** End Patch` and preserve
separator handling after `*** End of File`.
- Reject duplicate environment ID preambles explicitly.
- Remove the duplicate batch hunk parser and its implementation-specific
tests.
The change removes 201 net lines while retaining focused coverage for
the unified parser's boundary behavior.
## Validation
- `just test -p codex-apply-patch`
- Compared a 24-hour corpus of 2,788,059 observed `apply_patch` payloads
against the previous batch parser. All 2,779,502 accepted payloads
produced identical hunks, canonical patch text, and environment IDs; the
remaining 8,557 payloads were rejected by both parsers, with zero
acceptance or payload mismatches.
## Summary
- expose the remote plugin detail endpoint's `share_url` as nullable
`PluginDetail.shareUrl`
- preserve existing `PluginSummary.shareContext` behavior for local and
workspace sharing flows
- regenerate the app-server TypeScript and JSON schema fixtures
## Why
The remote plugin detail response already includes a canonical
`share_url`, but that value was not surfaced by `plugin/read` for global
plugins. Global plugins intentionally have no `shareContext`, so using
that model for the URL would change the semantics consumed by the
existing share modal.
## User impact
Codex clients can use `PluginDetail.shareUrl` for a remote plugin's
copy-link action, including when the plugin is disabled by an
administrator, without changing existing share-modal or ownership
behavior.
## Validation
- `cargo test -p codex-app-server
plugin_read_includes_share_url_for_admin_disabled_remote_plugin`
- `cargo test -p codex-app-server-protocol

- `cargo test -p codex-app-server-protocol
json_schema_fixtures_match_generated`
- `cargo fmt --all`
## Why
Sandbox cwd values can cross app-server and exec-server host boundaries.
They should retain URI semantics until the receiving host validates them
instead of being interpreted early as native paths.
## What
- Carry `PathUri` through filesystem sandbox contexts, sandbox commands,
and transform inputs.
- Convert command and policy cwd once in `SandboxManager::transform`,
then keep launch requests native.
- Preserve sandbox cwd over remote filesystem transport and reject
non-native URIs without fallback.
- Cache paired native/URI turn-environment cwd values during migration,
with immutable access to keep them synchronized.
- Extend existing protocol, forwarding, transform, and core runtime
tests.
## Summary
Adds a `RealtimeConversationArchitecture` option for realtime
conversation startup, with `realtimeapi` as the default and `avas` as an
opt-in architecture.
The AVAS path is limited to realtime v1 conversational WebRTC starts,
and WebRTC call creation appends `intent=quicksilver&architecture=avas`
to `/v1/realtime/calls`. The existing sideband websocket still joins by
`call_id`.
This also exposes the per-session architecture override through
app-server v2 `thread/realtime/start` params and updates the config
schema for `[realtime].architecture`.

## Summary
Replace Hatchling with uv's build backend for the Python SDK. The
backend infers the `src/openai_codex` module from the normalized project
name and standard source layout, so no uv-specific package configuration
is required.
This keeps Python packaging within the uv toolchain already used for
dependency management and release builds. A controlled before-and-after
PEP 517 comparison produced identical wheel package paths, bytes,
permissions, and semantic metadata. The sdist retains the SDK package
tree, root README, and project metadata while dropping the unrelated
examples README that Hatch included through its broad include matching.
## Why
The TUI rejected playful `/goal` spellings such as `/goooooooooooal`,
even though Codex Apps accepts them for the World Cup promotion. This
keeps the TUI behavior consistent without changing how the canonical
command is presented.
## How it works
Built-in command lookup recognizes lowercase `go+al` as the existing
`goal` command after normal exact-name parsing fails. The command
catalog remains unchanged, so autocomplete continues to advertise
`/goal` normally.
## Verification
Added lookup-level and end-to-end TUI coverage for the flexible
spelling. The focused tests, scoped Clippy checks, and formatting pass.
The full `codex-tui` suite passed 2,833 of 2,835 tests; the two failing
guardian feature-flag tests reproduce unchanged on fresh `origin/main`.
## Summary
Choosing “Don’t remind me” can silently fail when `version.json`
disappears before dismissal because `dismiss_version` returns success
without writing anything. The same update can then reappear on the next
launch.
Initialize a minimal `VersionInfo` from the selected version when the
cache cannot be read, then persist the dismissal through the existing
write path.
Fixes#27147
## Summary
`just fmt` previously used `uv run --with ruff` to make Ruff available.
Because `--with` creates an ephemeral overlay outside the project
lockfile, uv periodically re-resolved Ruff (by default every 10 minutes)
instead of using the version recorded in `uv.lock`.
Move the Python SDK tooling dependencies from the published `dev` extra
into `format`, `test`, and composed `dev` dependency groups. The
formatter now selects only the locked `format` group, contributor and CI
setup explicitly sync the `dev` group, and CI and release commands reuse
that environment with `--frozen --no-sync`. The scripts formatter also
uses its project's locked Ruff dependency instead of an ephemeral
overlay.
Validated the Python 3.12 SDK suite (119 passed, 38 skipped) and the
repository formatter.

## Summary
- add `approvals_reviewer` support to `[apps._default]`
- resolve connected-app reviewers in per-app, app-default, then global
order
- expose the setting through the v2 config API and regenerate schema
fixtures
## Context
PR #25167 added `apps.<connector_id>.approvals_reviewer`, but the shared
app defaults table could not specify the reviewer. This extends the same
behavior to `[apps._default]` while preserving per-app overrides.
Managed `allowed_approvals_reviewers` requirements still constrain both
default and per-app values. A disallowed app value falls back to the
global reviewer, and non-app MCP servers continue using the global
reviewer.
## Testing
- `just write-config-schema`
- `just write-app-server-schema`
- `just fmt`
- `just test -p codex-config`
- `just test -p codex-core app_approvals_reviewer`
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server config_read_includes_apps`
## Why
Fixes#27735.
Side conversations are ephemeral forks, and thread rollback currently
requires persisted thread history. The normal backtrack path already
rejected editing previous prompts in side conversations, but
transcript-mode backtrack could still call the rollback path and surface
the core `thread/rollback` failure as a TUI error.
## What changed
- Moved the existing side-conversation edit rejection message into
`app_backtrack.rs` so backtrack rollback code can reuse it.
- Added a side-conversation guard in `apply_backtrack_rollback` so
transcript-mode confirmation is rejected before submitting
`thread/rollback`.
## Verification
- `just test -p codex-tui
app::tests::side_backtrack_rejection_reports_unavailable_message_snapshot`
## Summary
- serialize the remaining login tests that mutate or read the
process-global auth environment
- include Bedrock auth-manager tests in the existing `codex_auth_env`
serial group
## Root cause
The login unit-test binary runs tests concurrently. One test removed
`CODEX_ACCESS_TOKEN` without joining the existing serial group, while
several Bedrock tests constructed `AuthManager` and read that same
process-global environment outside the group. An interleaving could
restore a stale personal access token while another test was loading
file-backed auth, causing the observed mismatched `/whoami` request
count and related auth-state flakes.
## Verification
- `just fmt`
- `git diff --check`
- `bazel test //codex-rs/login:login-unit-tests --nocache_test_results
--runs_per_test=20 --test_output=errors` (20/20 passed)
- `just test -p codex-login` (135/135 passed)
## Summary
- restore source-specific wording across the `/import` picker, lifecycle
messages, diagnostics, and help text
- update the matching Unix and Windows snapshots
- leave import behavior unchanged
## Why
The import path currently supports one source, so the UI should identify
that source directly instead of presenting the flow as
provider-agnostic.
## Validation
- `just test -p codex-tui external_agent_config_migration` (12 passed)
- `just fix -p codex-tui`
- `just fmt`
## Why
We want a thread-selected plugin to eventually expose stdio MCP servers
that run on the executor owning that plugin.
The existing plugin MCP parser lived inside `core-plugins` and was
coupled to the host filesystem loader. Reusing it from an executor
provider would either duplicate MCP normalization or make the plugin
package layer own MCP runtime semantics. This PR creates the shared
MCP-owned boundary first.
In simple terms:
```text
plugin .mcp.json
|
v
shared parser in codex-mcp
|
+-- Declared placement: preserve current local-plugin behavior
|
+-- Environment placement: produce config bound to one executor
```
This builds on the authority-bound plugin descriptors from #27692. It
intentionally does not discover, register, or launch executor MCP
servers yet.
## What changed
- Moved plugin MCP file parsing and normalization from `core-plugins`
into `codex-mcp`.
- Kept support for both existing file shapes: a top-level server map and
an object containing `mcpServers`.
- Kept per-server failure isolation: one invalid server does not discard
valid siblings, while malformed top-level JSON still fails the whole
file.
- Updated the existing local plugin loader to use `Declared` placement,
preserving its current transport, OAuth, relative `cwd`, and error
behavior.
- Added `Environment` placement for the next stacked PR:
- the selected environment ID overrides anything declared by the plugin;
- missing stdio `cwd` defaults to the plugin root;
- relative `cwd` is resolved beneath the plugin root and cannot traverse
outside it;
- bare or source-less environment-variable references resolve on a
non-local executor;
- explicit orchestrator environment-variable forwarding is rejected for
executor-owned plugins.
## User impact
None in this PR. Existing local plugin MCP loading follows the same
behavior through the shared parser. The executor placement mode is not
connected to thread startup until the follow-up registration PR.
## Assumptions
- A selected capability root's environment is authoritative. A plugin
cannot redirect its stdio process to the orchestrator or another
executor.
- Relative working directories belong under the plugin package root.
Explicit absolute working directories remain valid within the owning
environment.
- For a non-local executor, unqualified environment-variable names refer
to that executor. Reading an orchestrator variable requires an explicit
contract and is rejected for now.
- Parsing only produces normalized `McpServerConfig` values. Process
startup remains owned by the existing MCP runtime and connection
manager.
## Follow-ups
1. Add the executor MCP provider and catalog registration: read the
selected plugin's MCP config through the same executor filesystem,
support stdio only, freeze the result per active thread, apply managed
policy, and resolve name collisions as discovered plugin < selected
plugin < explicit config.
2. Install that provider in app-server and add an end-to-end test
proving `thread/start.selectedCapabilityRoots` launches and calls the
MCP tool on the selected executor, preserves the frozen registration
across refresh, and does not expose it to an unselected thread.
3. After the initial executor-stdio vertical, define
resume/fork/environment-replacement semantics, executor HTTP placement,
warning delivery, common MCP tool-context bounds, and move remaining MCP
source composition above core.
## Verification
- `cargo check -p codex-mcp -p codex-core-plugins --tests`
- `just bazel-lock-check`
- Added focused parser coverage for legacy local normalization, executor
authority, working-directory handling, and environment-variable
sourcing.
## Why
CCA can select a capability root that lives in an executor environment,
but
Codex only had a host-filesystem plugin loader. Before selected executor
plugins can contribute MCP servers, we need a small package boundary
that can
answer:
> Does this selected root contain a plugin, and if so, what does its
manifest
> declare?
The answer must come from the selected environment's filesystem. A
failed
executor lookup must never fall back to the orchestrator filesystem.
## What this changes
This PR introduces:
```rust
PluginProvider::resolve(root)
-> Result<Option<ResolvedPlugin>, Error>
```
`ExecutorPluginProvider` resolves one `SelectedCapabilityRoot` through
its
exact `environment_id`. It checks the recognized manifest locations,
reads the
manifest through that environment's `ExecutorFileSystem`, and returns an
inert
`ResolvedPlugin` containing:
- the opaque selected-root ID;
- the environment-bound plugin root;
- the authority-bound manifest resource;
- parsed metadata and authority-bound component locators.
Descriptor construction rejects manifest or component paths outside the
selected package root, so consumers cannot accidentally lose the package
boundary when they receive a resolved plugin.
If the root has no plugin manifest, resolution returns `None`, allowing
the
caller to treat it as a standalone capability such as a skill.
```text
selected root: repo -> env-1:/workspace/repo
|
| env-1 filesystem only
v
.codex-plugin/plugin.json
|
v
ResolvedPlugin { authority, root, manifest }
```
The existing host loader and the new executor provider now share the
same
manifest parser. Existing `codex-core-plugins::manifest` type paths
remain
available through re-exports, so host behavior and callers are
unchanged.
## Scope
This is intentionally a non-user-visible package-resolution PR. It does
not:
- parse or register plugin MCP server configurations;
- activate skills, connectors, hooks, or MCP servers;
- change app-server wiring;
- introduce host fallback, caching, or lifecycle behavior.
#27670 has merged, and this PR is now based directly on `main`. Together
with
the resolved MCP catalog from #27634, it establishes the inputs needed
for the
executor stdio MCP vertical without changing the existing MCP runtime.
## Follow-up
The next PR will consume `ResolvedPlugin`, read its declared/default MCP
config
through the same executor filesystem, bind supported stdio servers to
that
environment, and feed those registrations into the resolved MCP catalog.
An
app-server E2E will prove that selecting an executor plugin exposes and
invokes
its tool on the owning executor.
Resume/fork semantics, dynamic environment replacement, and non-stdio
placement remain separate lifecycle decisions.
## Validation
- `just fmt`
- `cargo check --tests -p codex-plugin -p codex-core-plugins`
- `just bazel-lock-check`
- `git diff --check`
Test targets were compiled but not executed locally; CI will run the
test and
Clippy suites.
