This is PR 2 of the Python SDK PyPI publishing split. [PR
1](https://github.com/openai/codex/pull/18862) refreshed the generated
SDK bindings; this PR makes the runtime package itself publishable, and
PR 3 will wire the SDK package/version pinning to this runtime package.
## Summary
- Rename the runtime distribution to `openai-codex-cli-bin` while
keeping the import package as `codex_cli_bin`.
- Make the runtime package wheel-only and build `py3-none-<platform>`
wheels instead of interpreter-specific wheels.
- Add `stage-runtime --codex-version` and `--platform-tag` so release
staging can produce the platform wheel matrix from Codex release tags.
- Add focused artifact workflow tests for version normalization,
platform tag injection, and runtime wheel metadata.
## Why Rename
There is already an unofficial PyPI package,
[`codex-bin`](https://pypi.org/project/codex-bin/), distributing OpenAI
Codex binaries. Publishing the official SDK runtime dependency as
`openai-codex-cli-bin` makes the ownership clear, avoids confusing the
SDK-pinned runtime wheel with that unowned wrapper, and keeps the import
package unchanged as `codex_cli_bin`.
## Tests
- `uv run --extra dev pytest
tests/test_artifact_workflow_and_binaries.py` -> 21 passed
- `uv run --extra dev python scripts/update_sdk_artifacts.py
stage-runtime /tmp/codex-python-pr2-rebased/runtime-stage
/tmp/codex-python-pr2-rebased/codex --codex-version
rust-v0.116.0-alpha.1 --platform-tag macosx_11_0_arm64`
- `uv run --with build --extra dev python -m build --wheel
/tmp/codex-python-pr2-rebased/runtime-stage`
- `uv run --with twine --extra dev twine check
/tmp/codex-python-pr2-rebased/runtime-stage/dist/openai_codex_cli_bin-0.116.0a1-py3-none-macosx_11_0_arm64.whl`
## Note
- Full `uv run --extra dev pytest` currently fails because regenerating
from schemas already on `main` adds new DeviceKey Python types. I left
that generated catch-up out of this runtime-only PR.
## Summary
This updates the embedded `imagegen` system skill in `codex-rs/skills`
with the ImageGen 2 skill changes from `openai/skills-internal#87`.
The bundled skill now keeps normal image generation/editing on the
built-in `image_gen` path, updates the CLI fallback defaults to
`gpt-image-2`, and routes explicit transparent-output requests through
`gpt-image-1.5` with clear guidance that `gpt-image-2` does not support
transparent backgrounds.
## Details
- Update `SKILL.md` routing guidance for built-in vs CLI fallback
behavior.
- Update CLI/API references for `gpt-image-2` size constraints, quality
options, near-4K sizes, and unsupported options.
- Update `scripts/image_gen.py` defaults and validation:
- default model `gpt-image-2`
- default size `auto`
- default quality `medium`
- reject transparent backgrounds on `gpt-image-2`
- reject `input_fidelity` on `gpt-image-2`
- validate flexible `gpt-image-2` sizes and suggest `3824x2160` /
`2160x3824` for near-4K requests
- Update prompt/reference docs with the new model and routing guidance.
## Validation
- `cargo test -p codex-skills`
- `git diff --check`
- Manual CLI dry-runs for:
- default `gpt-image-2` payload
- `3824x2160` near-4K size acceptance
- `3840x2160` rejection with near-4K guidance
- transparent background rejection on `gpt-image-2`
- transparent background acceptance on `gpt-image-1.5`
- `input_fidelity` rejection on `gpt-image-2`
Bazel target check was not run locally because `bazel` is not installed
in this environment.
## Why
`wait_agent` can be called while mailbox mail is already pending. The
previous implementation subscribed for future mailbox sequence changes
and then waited for the next notification. If the mail was queued before
that wait started, no new notification arrived, so the tool could sit
until `timeout_ms` even though mail was ready to deliver.
## What Changed
- Added `Session::has_pending_mailbox_items()` for checking pending
mailbox mail through the session API.
- Updated `multi_agents_v2::wait` to return immediately when pending
mailbox mail already exists before sleeping on a new mailbox sequence
update.
- Reworked the regression coverage in `multi_agents_tests.rs` so already
queued mailbox mail must wake `wait_agent` promptly.
Relevant code:
- [`wait_agent` pending-mail
check](aa8ca06e83/codex-rs/core/src/tools/handlers/multi_agents_v2/wait.rs (L55-L60))
-
[`Session::has_pending_mailbox_items`](aa8ca06e83/codex-rs/core/src/session/mod.rs (L2979-L2981))
-
[`multi_agent_v2_wait_agent_returns_for_already_queued_mail`](aa8ca06e83/codex-rs/core/src/tools/handlers/multi_agents_tests.rs (L2854))
## Verification
- `cargo test -p codex-core
multi_agent_v2_wait_agent_returns_for_already_queued_mail`
## Summary
- Teach app-server `thread/list` to accept either a single `cwd` or an
array of cwd filters, returning threads whose recorded session cwd
matches any requested path
- Add `useStateDbOnly` as an explicit opt-in fast path for callers that
want to answer `thread/list` from SQLite without scanning JSONL rollout
files
- Preserve backwards compatibility: by default, `thread/list` still
scans JSONL rollouts and repairs SQLite state
- Wire the new cwd array and SQLite-only options through app-server,
local/remote thread-store, rollout listing, generated TypeScript/schema
fixtures, proto output, and docs
## Test Plan
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-rollout`
- `cargo test -p codex-thread-store`
- `cargo test -p codex-app-server thread_list`
- `just fmt`
- `just fix -p codex-app-server-protocol -p codex-rollout -p
codex-thread-store -p codex-app-server`
- `cargo build -p codex-cli --bin codex`
## Why
Guardian analytics includes time-to-first-token, but the Guardian
reviewer runs as a normal Codex session and `TurnCompleteEvent` did not
expose TTFT. The timing needs to flow through the standard
turn-completion protocol so Guardian review analytics can consume the
same value as the rest of the session machinery.
## What changed
Adds optional `time_to_first_token_ms` to `TurnCompleteEvent` and
populates it from `TurnTiming`. The value is carried through app-server
thread history, rollout reconstruction, TUI/app-server adapters, and
Guardian review session handling.
Guardian review analytics now captures TTFT from the reviewer
turn-complete event when available. Existing tests and fixtures are
updated to set the new optional field to `None` where TTFT is not
relevant.

## Why
The Guardian review event needs to report whether the action shown to
Guardian was truncated. That field should come from the same truncation
path used to build the Guardian prompt, rather than being inferred after
the fact.
## What changed
Plumbs truncation metadata through Guardian action formatting, prompt
construction, review session execution, and analytics emission.
`guardian_truncate_text` now reports both the rendered text and whether
it inserted the truncation marker, and `reviewed_action_truncated` is
set from that prompt-building result.
This keeps the analytics field aligned with the model-visible reviewed
action while preserving the existing Guardian prompt behavior.
## Verification
- Guardian truncation tests cover both truncated and non-truncated
action payloads.
- Guardian review tests assert the review session metadata and
truncation field are propagated.

## Why
Guardian approvals now run as review sessions, but Codex analytics did
not have a terminal event for those reviews. That made it hard to
measure approval outcomes, failure modes, Guardian session reuse, model
metadata, token usage, and timing separately from the parent turn.
## What changed
Adds `codex_guardian_review` analytics emission for Guardian approval
reviews. The event is emitted from the Guardian review path with review
identity, target item id, approval request source, a PII-minimized
reviewed-action shape, terminal decision/status, failure reason,
Guardian assessment fields, Guardian session metadata, token usage, and
timing metadata.
The reviewed-action payload intentionally omits high-risk fields such as
shell commands, working directories, argv, file paths, network
targets/hosts, rationale, retry reason, and permission justifications.
It also classifies prompt-build failures separately from Guardian
session/runtime failures so fail-closed cases are distinguishable in
analytics.
## Verification
- Guardian review analytics tests cover terminal success,
timeout/cancel/fail-closed paths, session metadata, and token usage
plumbing.
- `cargo clippy -p codex-core --lib --tests -- -D warnings`

## Why
The `PermissionProfile` migration needs app-server clients to see the
same constrained permission model that core is using at runtime. Before
this PR, thread lifecycle responses only exposed the legacy
`SandboxPolicy` shape, so clients still had to infer active permissions
from sandbox fields. That makes downstream resume, fork, and override
flows harder to make `PermissionProfile`-first.
External sandbox policies are intentionally excluded from this canonical
view. External enforcement cannot be round-tripped as a
`PermissionProfile`, and exposing a lossy root-write profile would let
clients accidentally change sandbox semantics if they echo the profile
back later.
## What changed
- Adds the app-server v2 `PermissionProfile` wire shape, including
filesystem permissions and glob scan depth metadata.
- Adds `PermissionProfileNetworkPermissions` so the profile response
does not expose active network state through the older
additional-permissions naming.
- Returns `permissionProfile` from thread start, resume, and fork
responses when the active sandbox can be represented as a
`PermissionProfile`.
- Keeps legacy `sandbox` in those responses for compatibility and
documents `permissionProfile` as canonical when present.
- Makes lifecycle `permissionProfile` nullable and returns `null` for
`ExternalSandbox` to avoid exposing a lossy profile.
- Regenerates the app-server JSON schema and TypeScript fixtures.

* #18279
* __->__ #18278
`codex sandbox windows` previously did a one-shot spawn for all
commands.
This change uses the `unified_exec` session to spawn long-lived
processes instead, and implements a simple bridge to forward stdin to
the spawned session and stdout/stderr from the spawned session back to
the caller.
It also fixes a bug with the new shared spawn context code where the
"no-network env" was being applied to both elevated and unelevated
sandbox spawns. It should only be applied for the unelevated sandbox
because the elevated one uses firewall rules instead of an env-based
network suppression strategy.
## Summary
This PR adds `CodexAuth::AgentIdentity` as an explicit auth mode.
An AgentIdentity auth record is a standalone `auth.json` mode. When
`AuthManager::auth().await` loads that mode, it registers one
process-scoped task and stores it in runtime-only state on the auth
value. Header creation stays synchronous after that because the task is
initialized before callers receive the auth object.
This PR also removes the old feature flag path. AgentIdentity is
selected by explicit auth mode, not by a hidden flag or lazy mutation of
ChatGPT auth records.
Reference old stack: https://github.com/openai/codex/pull/17387/changes
## Design Decisions
- AgentIdentity is a real auth enum variant because it can be the only
credential in `auth.json`.
- The process task is ephemeral runtime state. It is not serialized and
is not stored in rollout/session data.
- Account/user metadata needed by existing Codex backend checks lives on
the AgentIdentity record for now.
- `is_chatgpt_auth()` remains token-specific.
- `uses_codex_backend()` is the broader predicate for ChatGPT-token auth
and AgentIdentity auth.
## Stack
1. https://github.com/openai/codex/pull/18757: full revert
2. https://github.com/openai/codex/pull/18871: isolated Agent Identity
crate
3. This PR: explicit AgentIdentity auth mode and startup task allocation
4. https://github.com/openai/codex/pull/18811: migrate Codex backend
auth callsites through AuthProvider
5. https://github.com/openai/codex/pull/18904: accept AgentIdentity JWTs
and load `CODEX_AGENT_IDENTITY`
## Testing
Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.
## Why
`Permissions` should not store a separate `PermissionProfile` that can
drift from the constrained `SandboxPolicy` and network settings. The
active profile needs to be derived from the same constrained values that
already honor `requirements.toml`.
## What changed
This adds derivation of the active `PermissionProfile` from the
constrained runtime permission settings and exposes that derived value
through config snapshots and thread state. The app-server can then
report the active profile without introducing a second source of truth.

## Summary
The Bedrock Mantle SigV4 auth provider currently looks like it can
lazily load `AwsAuthContext`, but the provider is only constructed after
`resolve_auth_method` has already loaded that context. Because
`with_context` always pre-populates the `OnceCell`, the
`get_or_try_init` fallback is unused in normal operation and makes the
provider lifecycle harder to reason about.
This change removes that dead lazy-loading path and makes the actual
behavior explicit:
- `BedrockAuthMethod::AwsSdkAuth` carries only the resolved
`AwsAuthContext`.
- `BedrockMantleSigV4AuthProvider` stores the resolved context directly.
- request signing uses the stored context without going through
`OnceCell`.
The existing eager AWS auth resolution behavior is unchanged; this is a
simplification of the provider state, not a behavior change.
## Testing
- `cargo shear`
- `cargo test -p codex-model-provider`
- `just bazel-lock-check`
## Summary
- Keep the guardian policy installed as guardian base instructions.
- Clear inherited parent `developer_instructions` for guardian review
sessions.
- Update guardian config tests to assert developer instructions are
cleared and policy text is sourced from base instructions.
## Why
Guardian review sessions are intended to run under an isolated guardian
policy. Because the guardian config is cloned from the parent config,
inherited custom or managed developer instructions could otherwise
remain active and conflict with guardian review behavior.
## Validation
- `just fmt`
- `cargo test -p codex-core guardian_review_session_config`

## Why
A [Windows Cargo
build](https://github.com/openai/codex/actions/runs/24754807756/job/72425641062)
on `main` timed out in several unrelated-looking suites at the same
time:
- `codex-app-server` account tests failed before account logic, while
`mcp.initialize()` was waiting for the first JSON-RPC response.
- `codex-core` `apply_patch_cli` tests timed out while running full
Codex/apply_patch turns.
- `codex-windows-sandbox` legacy session tests timed out while creating
restricted-token child processes and private desktops.
The app-server log reached the test harness write path in
[`McpProcess::initialize_with_params`](731b54d08f/codex-rs/app-server/tests/common/mcp_process.rs (L244-L263)),
but never printed the matching stdout read from
[`read_jsonrpc_message`](731b54d08f/codex-rs/app-server/tests/common/mcp_process.rs (L1123-L1128)).
The server initialize handler is a small bookkeeping/response path
([`message_processor.rs`](731b54d08f/codex-rs/app-server/src/message_processor.rs (L601-L728))),
so the failure looks like Windows runner process/pipe scheduling
starvation rather than account-specific behavior.
## What Changed
This updates `.config/nextest.toml` to serialize two process-heavy sets:
- `codex-core` tests matching `package(codex-core) & kind(test) &
test(apply_patch_cli)`
- `codex-windows-sandbox` tests matching `package(codex-windows-sandbox)
& test(legacy_)`
`codex-app-server` integration tests were already serialized inside
their own package; this change reduces overlap with the other suites
that were saturating the runner at the same time.
## Verification
- `cargo nextest list --filterset "package(codex-core) & kind(test) &
test(apply_patch_cli)"`
- `cargo nextest list --filterset "package(codex-windows-sandbox) &
test(legacy_)"`
The Windows sandbox filter naturally lists no tests on macOS, but it
validates the nextest filter/config syntax locally.
## Why
The fast `rust-ci` workflow decides whether to run the cross-platform
`argument-comment-lint` job based on changed paths. PRs that touch
Rust-adjacent Bazel wrapper files, such as `defs.bzl` or
`workspace_root_test_launcher.*.tpl`, can change how Rust tests and lint
targets behave without changing any `.rs` files.
When that detector returned false, GitHub skipped the matrix job before
expanding it. That produced a single skipped check named `Argument
comment lint - ${{ matrix.name }}` instead of the Linux, macOS, and
Windows check names that branch protection expects, leaving the PR
unable to go green when those matrix checks are required.
## What Changed
- Treat root Bazel wrapper files as `argument-comment-lint` relevant
changes.
- Keep the `argument_comment_lint_prebuilt` matrix job materialized for
every PR so the per-platform check names always exist.
- Add a single gate step that decides whether the real lint work should
run.
- Move the checkout-adjacent Bazel setup and OS-specific lint commands
into `.github/actions/run-argument-comment-lint/action.yml` so the
workflow does not repeat the same path-detection condition on each step.
## Verification
- Parsed `.github/workflows/rust-ci.yml` and
`.github/actions/run-argument-comment-lint/action.yml` with Python YAML
loading.
- Simulated the workflow path-matching shell conditions for the root
Bazel wrapper files and confirmed they set `argument_comment_lint=true`.
## Why
The exec-server still needs platform sandbox inputs, but the migration
should preserve the `PermissionProfile` that produced them. Keeping only
the derived legacy sandbox map would keep `SandboxPolicy` as the
effective abstraction and would make full-disk vs. restricted profiles
harder to preserve as the permissions stack starts round-tripping
profiles.
`PermissionProfile` entries can also be cwd-sensitive (`:cwd`,
`:project_roots`, relative globs), so the exec-server must carry the
request sandbox cwd instead of resolving those entries against the
long-lived exec-server process cwd.
## What changed
`FileSystemSandboxContext` now carries `permissions: PermissionProfile`
plus an optional `cwd`:
- removed `sandboxPolicy`, `sandboxPolicyCwd`,
`fileSystemSandboxPolicy`, and `additionalPermissions`
- added `permissions` and `cwd`
- kept the platform knobs `windowsSandboxLevel`,
`windowsSandboxPrivateDesktop`, and `useLegacyLandlock`
Core turn and apply-patch paths populate the context from the active
runtime permissions and request cwd. Exec-server derives platform
`SandboxPolicy`/`FileSystemSandboxPolicy` at the filesystem boundary,
adds helper runtime reads there, and rejects cwd-dependent profiles that
arrive without a cwd.
The legacy `FileSystemSandboxContext::new(SandboxPolicy)` constructor
now preserves the old workspace-write conversion semantics for
compatibility tests/callers.

## Why
A Mac Bazel CI run saw `remote_notifications_arrive_over_websocket` fail
during shutdown with `remote app-server shutdown channel is closed`
(https://app.buildbuddy.io/invocation/9dac05d6-ae20-40f9-b627-fca6e91cf127).
The remote websocket worker can legitimately finish while `shutdown()`
is waiting for the shutdown acknowledgement: after the test server sends
a notification and exits, the worker may deliver the required disconnect
event, observe that the caller has dropped the event receiver, and exit
before it sends the shutdown one-shot.
That state is already terminal cleanup, not a failed shutdown, so
callers should not see a `BrokenPipe` from the acknowledgement channel.
## What Changed
- Treat a closed remote shutdown acknowledgement as an already-exited
worker while still propagating websocket close errors when the worker
returns them.
- Added a deterministic regression test for the interleaving where the
shutdown command is received and the worker exits before replying.
## Verification
- `cargo test -p codex-app-server-client`
- New test:
`remote::tests::shutdown_tolerates_worker_exit_after_command_is_queued`
Add a temporary internal remote_plugin feature flag that merges remote
marketplaces into plugin/list and routes plugin/read through the remote
APIs when needed, while keeping pure local marketplaces working as
before.

## Why
The `codex-tui` Cargo test suite was catching stale snapshot
expectations, but the matching Bazel unit-test target was still green.
The TUI unit target is wrapped by `workspace_root_test` so tests run
from the repository root and Insta can resolve Cargo-like snapshot
paths. After native Bazel sharding was enabled for that wrapped target,
rules_rust also inserted its own sharding wrapper around the Rust test
binary.
Those two wrappers did not compose: rules_rust's sharding wrapper
expects to run from its own runfiles cwd, while `workspace_root_test`
deliberately changes cwd to the repo root before invoking the test. In
that configuration, the inner wrapper could fail to enumerate the Rust
tests and exit successfully with empty shards, so snapshot regressions
were not being exercised by Bazel.
## What Changed
- Stop enabling rules_rust's inner `experimental_enable_sharding` for
unit-test binaries created by `codex_rust_crate`.
- Keep the configured `shard_count` on the outer `workspace_root_test`
target.
- Add libtest sharding directly to `workspace_root_test_launcher.sh.tpl`
and `workspace_root_test_launcher.bat.tpl` after the launcher has
resolved the actual test binary and established the intended
repository-root cwd.
- Partition tests by a stable FNV-1a hash of each libtest test name,
matching the stable-shard behavior we wanted without depending on the
inner rules_rust wrapper.
- Preserve ad-hoc local test filters by running the resolved test binary
directly when explicit test args are supplied.
- On Windows, run selected libtest names from the shard list in bounded
PowerShell batches instead of concatenating every selected test into one
`cmd.exe` command line.
This PR is stacked on top of #18912, which contains only the snapshot
expectation updates exposed once the Bazel target actually runs the TUI
unit tests. It is also the reason #18916 becomes visible: once this
wrapper fix makes Bazel execute the affected `codex-core` test, that
test needs its own executable-path setup fixed.
## Verification
- `cargo test -p codex-tui`
- `bazel test //codex-rs/tui:tui-unit-tests --test_output=errors`
- `bazel test //codex-rs/tui:all --test_output=errors`
- `bash -n workspace_root_test_launcher.sh.tpl`
- Exercised the Windows PowerShell batching fragment locally with a fake
test binary and shard-list file.
## Summary
Add first-class Amazon Bedrock Mantle provider support so Codex can keep
using its existing Responses API transport with OpenAI-compatible
AWS-hosted endpoints such as AOA/Mantle.
This is needed for the AWS launch path, where provider traffic should
authenticate with AWS credentials instead of OpenAI bearer credentials.
Requests are authenticated immediately before transport send, so SigV4
signs the final method, URL, headers, and body bytes that `reqwest` will
send.
## What Changed
- Added a new `codex-aws-auth` crate for loading AWS SDK config,
resolving credentials, and signing finalized HTTP requests with AWS
SigV4.
- Added a built-in `amazon-bedrock` provider that targets Bedrock Mantle
Responses endpoints, defaults to `us-east-1`, supports region/profile
overrides, disables WebSockets, and does not require OpenAI auth.
- Added Amazon Bedrock auth resolution in `codex-model-provider`: prefer
`AWS_BEARER_TOKEN_BEDROCK` when set, otherwise use AWS SDK credentials
and SigV4 signing.
- Added `AuthProvider::apply_auth` and `Request::prepare_body_for_send`
so request-signing providers can sign the exact outbound request after
JSON serialization/compression.
- Determine the region by taking the `aws.region` config first (required
for bearer token codepath), and fallback to SDK default region.
## Testing
Amazon Bedrock Mantle Responses paths:
- Built the local Codex binary with `cargo build`.
- Verified the custom proxy-backed `aws` provider using `env_key =
"AWS_BEARER_TOKEN_BEDROCK"` streamed raw `responses` output with
`response.output_text.delta`, `response.completed`, and `mantle-env-ok`.
- Verified a full `codex exec --profile aws` turn returned
`mantle-env-ok`.
- Confirmed the custom provider used the bearer env var, not AWS profile
auth: bogus `AWS_PROFILE` still passed, empty env var failed locally,
and malformed env var reached Mantle and failed with `401
invalid_api_key`.
- Verified built-in `amazon-bedrock` with `AWS_BEARER_TOKEN_BEDROCK` set
passed despite bogus AWS profiles, returning `amazon-bedrock-env-ok`.
- Verified built-in `amazon-bedrock` SDK/SigV4 auth passed with
`AWS_BEARER_TOKEN_BEDROCK` unset and temporary AWS session env
credentials, returning `amazon-bedrock-sdk-env-ok`.
## Why
`build_prompt_input` now initializes `ExecServerRuntimePaths`, which
requires a configured Codex executable path. The previous inline unit
test in `core/src/prompt_debug.rs` built a bare `test_config()` and then
failed before it could assert anything useful:
```text
Codex executable path is not configured
```
This coverage is also integration-shaped: it drives the public
`build_prompt_input` entry point through config, thread, and session
setup rather than testing a small internal helper in isolation.
Bazel CI did not catch this earlier because the affected test was behind
the same wrapped Rust unit-test path fixed by #18913. Before that
launcher/sharding fix, the outer `workspace_root_test` changed the
working directory for Insta compatibility while the inner `rules_rust`
sharding wrapper still expected its runfiles working directory. In
practice, Bazel could report success without executing the Rust test
cases in that shard. Once #18913 makes the wrapper run the Rust test
binary directly and shard with libtest arguments, this stale unit test
actually runs and exposes the missing `codex_self_exe` setup.
## What Changed
- Moved `build_prompt_input_includes_context_and_user_message` out of
`core/src/prompt_debug.rs`.
- Added `core/tests/suite/prompt_debug_tests.rs` and registered it from
`core/tests/suite/mod.rs`.
- Builds the test config with `ConfigBuilder` and provides
`codex_self_exe` using the current test executable, matching the
runtime-path invariant required by prompt debug setup.
- Preserves the existing assertions that the generated prompt input
includes both the debug user message and project-specific user

* #18913
* __->__ #18916
Fixes https://github.com/openai/codex/issues/16732.
## Why
`apply_patch` is Codex's primary file edit path, but it was not emitting
`PreToolUse` or `PostToolUse` hook events. That meant hook-based policy,
auditing, and write coordination could observe shell commands while
missing the actual file mutation performed by `apply_patch`.
The issue also exposed that the hook runtime serialized command hook
payloads with `tool_name: "Bash"` unconditionally. Even if `apply_patch`
supplied hook payloads, hooks would either fail to match it directly or
receive misleading stdin that identified the edit as a Bash tool call.
## What Changed
- Added `PreToolUse` and `PostToolUse` payload support to
`ApplyPatchHandler`.
- Exposed the raw patch body as `tool_input.command` for both
JSON/function and freeform `apply_patch` calls.
- Taught tool hook payloads to carry a handler-supplied hook-facing
`tool_name`.
- Preserved existing shell compatibility by continuing to emit `Bash`
for shell-like tools.
- Serialized the selected hook `tool_name` into hook stdin instead of
hardcoding `Bash`.
- Relaxed the generated hook command input schema so `tool_name` can
represent tools other than `Bash`.
## Verification
Added focused handler coverage for:
- JSON/function `apply_patch` calls producing a `PreToolUse` payload.
- Freeform `apply_patch` calls producing a `PreToolUse` payload.
- Successful `apply_patch` output producing a `PostToolUse` payload.
- Shell and `exec_command` handlers continuing to expose `Bash`.
Added end-to-end hook coverage for:
- A `PreToolUse` hook matching `^apply_patch$` blocking the patch before
the target file is created.
- A `PostToolUse` hook matching `^apply_patch$` receiving the patch
input and tool response, then adding context to the follow-up model
request.
- Non-participating tools such as the plan tool continuing not to emit
`PreToolUse`/`PostToolUse` hook events.
Also validated manually with a live `codex exec` smoke test using an
isolated temp workspace and temp `CODEX_HOME`. The smoke test confirmed
that a real `apply_patch` edit emits `PreToolUse`/`PostToolUse` with
`tool_name: "apply_patch"`, a shell command still emits `tool_name:
"Bash"`, and a denying `PreToolUse` hook prevents the blocked patch file
from being created.
## Summary
- add experimental turn/start.environments params for per-turn
environment id + cwd selections
- pass selections through core protocol ops and resolve them with
EnvironmentManager before TurnContext creation
- treat omitted selections as default behavior, empty selections as no
environment, and non-empty selections as first environment/cwd as the
turn primary
## Testing
- ran `just fmt`
- ran `just write-app-server-schema`
- not run: unit tests for this stacked PR

## Why
#18275 anchors session-scoped `:cwd` and `:project_roots` grants to the
request cwd before recording them for reuse. Relative deny glob entries
need the same treatment. Without anchoring, a stored session permission
can keep a pattern such as `**/*.env` relative, then reinterpret that
deny against a later turn cwd. That makes the persisted profile depend
on the cwd at reuse time instead of the cwd that was reviewed and
approved.
## What changed
`intersect_permission_profiles` now materializes retained
`FileSystemPath::GlobPattern` entries against the request cwd, matching
the existing materialization for cwd-sensitive special paths.
Materialized accepted grants are now deduplicated before deny retention
runs. This keeps the sticky-grant preapproval shape stable when a
repeated request is merged with the stored grant and both `:cwd = write`
and the materialized absolute cwd write are present.
The preapproval check compares against the same materialized form, so a
later request for the same cwd-relative deny glob still matches the
stored anchored grant instead of re-prompting or rejecting.
Tests cover both the storage path and the preapproval path: a
session-scoped `:cwd = write` grant with `**/*.env = none` is stored
with both the cwd write and deny glob anchored to the original request
cwd, cannot be reused from a later cwd, and remains preapproved when
re-requested from the original cwd after merging with the stored grant.
## Verification

## Summary
- tighten the external migration prompt snapshot around stable synthetic
fixture text
- add focused display_description tests for relative path rewriting and
plugin summaries
- split the path-format assertions into smaller, easier-to-read unit
tests
## Why
The previous prompt snapshot was coupled to path text that came from
detected migration items, which made it noisier and more brittle than
necessary. This change keeps the snapshot focused on stable UI structure
and moves dynamic path formatting checks into targeted unit tests.
## Validation
- cargo test -p codex-tui external_agent_config_migration::tests::
- cargo test -p codex-tui
external_agent_config_migration::tests::display_description_
- just fmt
## Notes
Per the repo instructions, I did not rerun tests after the final `just
fmt` pass.
This change aligns the `/statusline` and `/title` UIs around the same
normalized item model so both surfaces use consistent ids, labels, and
preview semantics. It keeps the shared preview work from #18435 ,
tightens the remaining mismatches by standardizing item naming, expands
title/status item coverage where appropriate, and makes `/title` preview
use the same title-specific formatting path as the real rendered
terminal title.
- Normalizes persisted item ids and keeps legacy aliases for
compatibility
- Aligns `status-line` and `terminal-title` items with the shared
preview model
- Routes `terminal-title` preview through title-specific formatting and
truncation
- Updates the affected status/title setup snapshots
Added to `/statusline`:
- status
- task-progress
Normalized in `/statusline`:
- model-name -> model
- project-root -> project-name
Added to `/title`:
- current-dir
- context-remaining
- context-used
- five-hour-limit
- weekly-limit
- codex-version
- used-tokens
- total-input-tokens
- total-output-tokens
- session-id
- fast-mode
- model-with-reasoning
Normalized in `/title`:
- project -> project-name
- thread -> thread-title
- model-name -> model
## Summary
Allow guardian to skip other fields and output only
`{"outcome":"allow"}` when the command is low risk.
This change lets guardian reviews use a non-strict text format while
keeping the JSON schema itself as plain user-visible schema data, so
transport strictness is carried out-of-band instead of through a schema
marker key.
## What changed
- Add an explicit `output_schema_strict` flag to model prompts and pass
it into `codex-api` text formatting.
- Set guardian reviewer prompts to non-strict schema validation while
preserving strict-by-default behavior for normal callers.
- Update the guardian output contract so definitely-low-risk decisions
may return only `{"outcome":"allow"}`.
- Treat bare allow responses as low-risk approvals in the guardian
parser.
- Add tests and snapshots covering the non-strict guardian request and
optional guardian output fields.
## Verification
- `cargo test -p codex-core guardian::tests::guardian`
- `cargo test -p codex-core guardian::tests::`
- `cargo test -p codex-core client_common::tests::`
- `cargo test -p codex-protocol
user_input_serialization_includes_final_output_json_schema`
- `cargo test -p codex-api`
- `git diff --check`
Note: `cargo test -p codex-core` was also attempted, but this desktop
environment injects ambient config/proxy state that causes unrelated
config/session tests expecting pristine defaults to fail.

## Summary
Adds the standalone `codex-rollout-trace` crate, which defines the raw
trace event format, replay/reduction model, writer, and reducer logic
for reconstructing model-visible conversation/runtime state from
recorded rollout data.
The crate-level design is documented in
[`codex-rs/rollout-trace/README.md`](https://github.com/openai/codex/blob/codex/rollout-trace-crate/codex-rs/rollout-trace/README.md).
## Stack
This is PR 1/5 in the rollout trace stack.
- [#18876](https://github.com/openai/codex/pull/18876): Add rollout
trace crate
- [#18877](https://github.com/openai/codex/pull/18877): Record core
session rollout traces
- [#18878](https://github.com/openai/codex/pull/18878): Trace tool and
code-mode boundaries
- [#18879](https://github.com/openai/codex/pull/18879): Trace sessions
and multi-agent edges
- [#18880](https://github.com/openai/codex/pull/18880): Add debug trace
reduction command
## Review Notes
This PR intentionally does not wire tracing into live Codex execution.
It establishes the data model and reducer contract first, with
crate-local tests covering conversation reconstruction, compaction
boundaries, tool/session edges, and code-cell lifecycle reduction. Later
PRs emit into this model.
The README is the best entry point for reviewing the intended trace
format and reduction semantics before diving into the reducer modules.
## Summary
- Adds a process-local, in-memory cookie store for ChatGPT HTTP clients.
- Limits cookie storage and replay to a shared ChatGPT host allowlist.
- Wires the shared store into the default Codex reqwest client and
backend client.
- Shares the ChatGPT host allowlist with remote-control URL validation
to avoid drift.
- Enables reqwest cookie support and updates lockfiles.
## Summary
This PR fully reverts the previously merged Agent Identity runtime
integration from the old stack:
https://github.com/openai/codex/pull/17387/changes
It removes the Codex-side task lifecycle wiring, rollout/session
persistence, feature flag plumbing, lazy `auth.json` mutation,
background task auth paths, and request callsite changes introduced by
that stack.
This leaves the repo in a clean pre-AgentIdentity integration state so
the follow-up PRs can reintroduce the pieces in smaller reviewable
layers.
## Stack
1. This PR: full revert
2. https://github.com/openai/codex/pull/18871: move Agent Identity
business logic into a crate
3. https://github.com/openai/codex/pull/18785: add explicit
AgentIdentity auth mode and startup task allocation
4. https://github.com/openai/codex/pull/18811: migrate auth callsites
through AuthProvider
## Testing
Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.
## Why
The device-key protocol needs an app-server implementation that keeps
local key operations behind the same request-processing boundary as
other v2 APIs.
app-server owns request dispatch, transport policy, documentation, and
JSON-RPC error shaping. `codex-device-key` owns key binding, validation,
platform provider selection, and signing mechanics. Keeping the adapter
thin makes the boundary easier to review and avoids moving local
key-management details into thread orchestration code.
## What changed
- Added `DeviceKeyApi` as the app-server adapter around
`DeviceKeyStore`.
- Converted protocol protection policies, payload variants, algorithms,
and protection classes to and from the device-key crate types.
- Encoded SPKI public keys and DER signatures as base64 protocol fields.
- Routed `device/key/create`, `device/key/public`, and `device/key/sign`
through `MessageProcessor`.
- Rejected remote transports before provider access while allowing local
`stdio` and in-process callers to reach the device-key API.
- Added stdio, in-process, and websocket tests for device-key validation
and transport policy.
- Documented the device-key methods in the app-server v2 method list.
## Test coverage
- `device_key_create_rejects_empty_account_user_id`
- `in_process_allows_device_key_requests_to_reach_device_key_api`
- `device_key_methods_are_rejected_over_websocket`
## Stack
This is PR 3 of 4 in the device-key app-server stack. It is stacked on
#18429.
## Validation
- `cargo test -p codex-app-server device_key`
- `just fix -p codex-app-server`
## Summary
Adds main-chat shortcuts for changing reasoning effort one step at a
time:
- `Alt+,` lowers reasoning (has the `<` arrow on the key)
- `Alt+.` raises reasoning (similarly, has the `>` arrow)
The shortcut updates the active session only. It does not persist the
selected reasoning level as the default for future sessions. In Plan
mode, it applies temporarily to Plan mode without opening the
global-vs-Plan scope prompt.
## Details
The shortcut uses the active model preset to decide which reasoning
levels are valid. If the current session has no explicit reasoning
effort, it starts from the model default. Each keypress moves to the
next supported level in the requested direction.
The shortcut only runs from the main chat surface. If a popup or modal
is open, input remains owned by that UI.
In Plan mode, the shortcut updates the in-memory Plan reasoning override
directly. The model/reasoning picker still keeps the existing scope
prompt for explicit picker changes.
## Notes
Ctrl-plus and Ctrl-minus were considered, but terminals do not deliver
those combinations consistently, so this PR uses Alt shortcuts instead.
If the current effort is unsupported by the selected model, the shortcut
skips to the nearest supported level in the requested direction. If
there is no valid step, it shows the existing boundary message.

## Why
PR #18431 exposed a Bazel clippy failure in the app-server unit-test
target across Linux, macOS, and Windows. The failing lint was
`clippy::await_holding_invalid_type`: two tracing tests serialized
access to global tracing state by holding a `tokio::sync::MutexGuard`
across awaited test work.
That serialization is still needed because the tests share
process-global tracing setup and exporter state, but it should not
require holding an async mutex guard through the whole test body.
## What changed
- Replaced the bespoke async `tracing_test_guard` helper with
`serial_test` on the two tracing tests that need global tracing
serialization.
- Removed the `#[expect(clippy::await_holding_invalid_type)]`
annotations and the lock guard callsites that Bazel clippy rejected.
## Validation
- `cargo test -p codex-app-server jsonrpc_span`
- `just fix -p codex-app-server`
- `git diff --check`
I also attempted the exact failing Bazel clippy target locally with
BuildBuddy disabled: `bazel --noexperimental_remote_repo_contents_cache
build --config=clippy --bes_backend= --remote_cache=
--experimental_remote_downloader= --
//codex-rs/app-server:app-server-unit-tests-bin`. That run did not reach
clippy because Bazel timed out downloading `libcap-2.27.tar.gz` from
`kernel.org`.
## Why
Device-key storage and signing are local security-sensitive operations
with platform-specific behavior. Keeping the core API in
`codex-device-key` keeps app-server focused on routing and business
logic instead of owning key-management details.
The crate keeps the signing surface intentionally narrow: callers can
create a bound key, fetch its public key, or sign one of the structured
payloads accepted by the crate. It does not expose a generic
arbitrary-byte signing API.
Key IDs cross into platform-specific labels, tags, and metadata paths,
so externally supplied IDs are constrained to the same auditable
namespace created by the crate: `dk_` followed by unpadded base64url for
32 bytes. Remote-control target paths are also tied to each signed
payload shape so connection proofs cannot be reused for enrollment
endpoints, or vice versa.
## What changed
- Added the `codex-device-key` workspace crate.
- Added account/client-bound key creation with stable `dk_` key IDs.
- Added strict `key_id` validation before public-key lookup or signing
reaches a provider.
- Added public-key lookup and structured signing APIs.
- Split remote-control client endpoint allowlists by connection vs
enrollment payload shape.
- Added validation for key bindings, accepted payload fields, token
expiration, and payload/key binding mismatches.
- Added flow-oriented docs on the validation helpers that gate provider
signing.
- Added protection policy and protection-class types without wiring a
platform provider yet.
- Added an unsupported default provider so platforms without an
implementation fail explicitly instead of silently falling back to
software-backed keys.
- Updated Cargo and Bazel lock metadata for the new crate and
non-platform-specific dependencies.
## Stack
This is stacked on #18428.
## Validation
- `cargo test -p codex-device-key`
- Added unit coverage for strict `key_id` validation before provider
use.
- Added unit coverage that rejects remote-control paths from the wrong
signed payload shape.
- `just bazel-lock-update`
- `just bazel-lock-check`
## Summary
This is the runtime/foundation half of the Windows sandbox unified-exec
work.
- add Windows sandbox `unified_exec` session support in
`windows-sandbox-rs` for both:
- the legacy restricted-token backend
- the elevated runner backend
- extend the PTY/process runtime so driver-backed sessions can support:
- stdin streaming
- stdout/stderr separation
- exit propagation
- PTY resize hooks
- add Windows sandbox runtime coverage in `codex-windows-sandbox` /
`codex-utils-pty`
This PR does **not** enable Windows sandbox `UnifiedExec` for product
callers yet because hooking this up to app-server comes in the next PR.
Windows sandbox advertising is intentionally kept aligned with `main`,
so sandboxed Windows callers still fall back to `ShellCommand`.
This PR isolates the runtime/session layer so it can be reviewed
independently from product-surface enablement.

This is the first step in splitting the Python SDK PyPI publish work
into reviewable layers: land the generated SDK refresh by itself before
changing packaging mechanics. The next PRs will make the runtime wheel
publishable, then wire the SDK package/version pinning to that runtime.
## Summary
- Refresh generated Python app-server v2 models and notification
registry from the current schema.
- Update the public API signature expectations for the newly generated
kwargs.
## Stack
- PR 1 of 3 for the Python SDK PyPI publishing split.
- Follow-up PRs will handle runtime wheel publishing mechanics, then
SDK/package version pinning.
## Tests
- `uv run --extra dev pytest` in `sdk/python` -> 51 passed, 37 skipped.
## Why
Permission approval responses must not be able to grant more access than
the tool requested. Moving this flow to `PermissionProfile` means the
comparison must be profile-shaped instead of `SandboxPolicy`-shaped, and
cwd-relative special paths such as `:cwd` and `:project_roots` must stay
anchored to the turn that produced the request.
## What changed
This implements semantic `PermissionProfile` intersection in
`codex-sandboxing` for file-system and network permissions. The
intersection accepts narrower path grants, rejects broader grants,
preserves deny-read carve-outs and glob scan depth, and materializes
cwd-dependent special-path grants to absolute paths before they can be
recorded for reuse.
The request-permissions response paths now use that intersection
consistently. App-server captures the request turn cwd before waiting
for the client response, includes that cwd in the v2 approval params,
and core stores the requested profile plus cwd for direct TUI/client
responses and Guardian decisions before recording turn- or
session-scoped grants. The TUI app-server bridge now preserves the
app-server request cwd when converting permission approval params into
core events.
