[codex] Restore setup helper UAC manifest (#25949 )

## Why

#23764 removed Windows resource stamping from `codex-windows-sandbox`,
but it also removed the setup helper's UAC manifest. That manifest was
doing more than cosmetic version metadata: Microsoft documents
`requestedExecutionLevel level="asInvoker"` as the setting that makes an
executable run at the same permission level as the process that started
it:
https://learn.microsoft.com/en-us/windows/win32/sbscs/application-manifests#trustinfo

In the reported session, `codex-windows-sandbox-setup.exe` was launched
for a non-elevated setup refresh and `CreateProcess` failed with `os
error 740` (`The requested operation requires elevation`). Restoring an
explicit `asInvoker` manifest records the helper's intended default
launch contract: normal launches inherit the caller's token, and
elevation only happens through the code paths that request it
explicitly.

The setup helper has two launch modes:

- setup refresh uses a normal `Command::new(...)` spawn and should never
trigger UAC
- full setup explicitly uses `ShellExecuteExW` with the `runas` verb
when elevation is required

Restoring `asInvoker` keeps refresh non-elevated by default while
preserving the explicit elevated path for full setup.

## What changed

- Restored a minimal `codex-windows-sandbox-setup.manifest` containing
only `requestedExecutionLevel level="asInvoker"`.
- Added a small build script that passes setup-helper-scoped manifest
linker args for MSVC and the Windows GNU/LLVM target used by Bazel.
- Wired the manifest into Bazel build-script data.

This does not restore `winres`, `FileDescription`, `ProductName`, or
package-wide resource stamping, so other Codex binaries that link
`codex-windows-sandbox` do not inherit metadata from this package.

## Verification

- `cargo fmt -p codex-windows-sandbox`
- `cargo build -p codex-windows-sandbox --bin
codex-windows-sandbox-setup`
- `cargo build -p codex-windows-sandbox --bin codex-command-runner`
- `cargo build -p codex-windows-sandbox --lib`
- Build-script output simulation for `CARGO_CFG_TARGET_ENV=msvc` emits
`/MANIFEST:EMBED` and `/MANIFESTINPUT:<manifest>`.
- Build-script output simulation for `CARGO_CFG_TARGET_ENV=gnu` +
`CARGO_CFG_TARGET_ABI=llvm` emits `-Wl,-Xlink=/manifest:embed` and
`-Wl,-Xlink=/manifestinput:<manifest>`.
- Inspected the built binaries and confirmed:
- `codex-windows-sandbox-setup.exe` contains `requestedExecutionLevel` /
`asInvoker`
  - `codex-command-runner.exe` does not contain those manifest strings
- Windows `VersionInfo` remains blank for `FileDescription` /
`ProductName`
- `just test -p codex-windows-sandbox` ran through Nextest, with 114
passing, 2 skipped, and 1 existing Windows sandbox failure:
`unified_exec::tests::legacy_non_tty_cmd_emits_output` fails with
`CreateRestrictedToken failed: 87`.

Implement v1 skills extension prompt injection (#26167 )

## Why

The skills extension needs a real turn-time path before host, executor,
or remote skills can be routed through it. The previous code was mostly
a placeholder catalog/provider sketch, so there was no bounded
available-skills fragment, no source-owned `SKILL.md` read, and no place
for warnings or per-turn selection state to live.

This PR makes `ext/skills` the authority-preserving flow for listing
candidate skills and injecting only explicitly selected main prompts,
without adding more of that logic to `codex-core`.

## What changed

- Expands catalog entries with `main_prompt`, display path, short
description, dependency metadata, enabled/prompt visibility flags, and
authority/package-aware read requests.
- Replaces the placeholder `providers/*` modules with
`SkillProviderSource` and `SkillProviders`, routing list/read/search
calls by source kind and surfacing provider failures as warnings.
- Adds bounded available-skills rendering and `SKILL.md` main-prompt
truncation before the fragments enter model context.
- Resolves explicit skill selections from structured `UserInput::Skill`,
skill-file mentions, `skill://...` paths, and plain `$skill` text
mentions, then reads selected prompts through their owning provider.
- Stores mutable per-thread skills config and per-turn
catalog/selection/warning state.
- Adds `install_with_providers` so tests and future host wiring can
supply concrete providers.

## Testing

- Not run locally.
- Added `codex-rs/ext/skills/tests/skills_extension.rs` coverage for
available-catalog injection, selected prompt injection through the
owning provider, and prompt-hidden skills that remain invokable.

fix: serialize goal progress accounting (#26155 )

## Why

Goal progress accounting can be reached from multiple completion paths
for the same thread. Each path takes a progress snapshot, writes the
usage delta, and then marks that snapshot as accounted. When two
tool-completion hooks run at the same time, they can both observe the
same unaccounted delta and charge it twice.

## What changed

- Added a per-thread progress-accounting permit to
`GoalAccountingState`.
- Held that permit across the snapshot/write/mark-accounted critical
section for active-turn, idle, and tool-finish accounting.
- Added regression coverage for parallel tool-finish hooks so a shared
token delta is charged once and only one progress event is emitted.

## Testing

- Not run locally.
- Added `parallel_tool_finish_accounts_active_goal_progress_once`.

skills: resolve per-turn catalogs from turn input context (#26106 )

## Why

The skills extension needs the resolved turn environments to build a
real per-turn `SkillListQuery`. The previous `TurnLifecycleContributor`
hook only had a turn id, so it could only seed a placeholder query and
never carry the executor authorities that executor-scoped skill routing
will need.

Moving catalog resolution onto `TurnInputContributor` puts the skills
extension on the same turn-preparation path that already has the
environment ids and working directories for the submitted turn, while
keeping the actual prompt injection work for follow-up changes.

## What changed

- switch `ext/skills` from `TurnLifecycleContributor` to
`TurnInputContributor`
- build `executor_authorities` from `TurnInputContext.environments` and
pass them through `SkillListQuery`
- keep storing the resolved catalog in `SkillsTurnState`, but drop the
placeholder query helper that no longer matches the real data flow
- update the extension TODOs to reflect that per-turn catalog resolution
now happens in the turn-input contributor, and that prompt/context
injection still needs to move later

## Testing

- Not run locally.

Reject MAv2 close_agent self-targets (#26144 )

## Why

`close_agent` is a parent-owned coordination tool: a worker should
return its result, then let its parent decide when to close it. Before
this change, if an MAv2 worker targeted itself, the resolved target
could flow through the normal close path and ask the agent control layer
to close the current conversation.

## What changed

- Reject `close_agent` when the resolved target is the current session's
`conversation_id`, returning a model-visible error that tells the worker
to return its result instead.
- Keep the guard after target resolution so it covers both thread-id
targets and task-path targets.
- Add coverage for self-targeting by thread id and by task name in
`multi_agents_tests.rs`.

Relevant code:

-
[`handle_close_agent`](https://github.com/openai/codex/blob/7c24e6641b693a3eed933dd376ce8f424ab6ea5f/codex-rs/core/src/tools/handlers/multi_agents_v2/close_agent.rs#L39-L57)

chore: extract context fragments into dedicated crate (#26122 )

## Why

`codex-core` currently owns the generic contextual-fragment trait and
several reusable fragment implementations. That makes it harder for
other crates to share the same host-owned model-input abstraction
without depending on all of `codex-core`.

This change extracts the reusable fragment machinery into a small
`codex-context-fragments` crate so future extension and skills work can
depend on the fragment abstraction directly.

## What Changed

- Added the `codex-context-fragments` crate with:
  - `ContextualUserFragment`
  - `FragmentRegistration` / `FragmentRegistrationProxy`
  - additional-context fragment types
- Moved `SkillInstructions` into `codex-core-skills`, since
skill-specific rendering belongs with skills rather than generic core
context machinery.
- Kept `codex-core` re-exporting the fragment types it still uses
internally, so existing call sites keep the same shape.
- Updated Cargo and Bazel workspace metadata for the new crate.

## Verification

- `cargo metadata --locked --format-version 1 --no-deps`
- `just bazel-lock-update`
- `just bazel-lock-check`

feat(app-server): add remote control client management RPCs (#25785 )

## Why

Remote-control clients need to list and revoke controller-device grants
without enabling or enrolling the local relay. These are signed-in
account-management operations, so coupling them to websocket, pairing,
enrollment, or persisted relay state would prevent clients from managing
stale grants from the picker.

Related enhancement request: N/A. This adds the Codex app-server surface
for the planned upstream environment-scoped revoke endpoint.

## What Changed

- Added experimental app-server v2 RPCs:
  - `remoteControl/client/list`
  - `remoteControl/client/revoke`
- Added picker-oriented protocol types and standard generated schema
fixtures. The list response intentionally omits backend account id,
enrollment status, and location fields.
- Added `app-server-transport/src/transport/remote_control/clients.rs`
for environment-scoped GET and DELETE requests. It builds escaped URL
path segments, forwards optional pagination query fields, sends ChatGPT
auth plus `chatgpt-account-id`, converts RFC3339 `last_seen_at` values
to Unix seconds, accepts `204 No Content` revoke responses, and retries
once after a `401`.
- Extracted shared ChatGPT auth loading and recovery into
`app-server-transport/src/transport/remote_control/auth.rs` so
websocket, pairing, and client management use the same account-auth
boundary.
- Retained the configured remote-control base URL on
`RemoteControlHandle` and resolve management URLs lazily, preserving
deferred validation while relay startup is disabled.
- Registered list as `global_shared_read("remote-control-clients")` and
revoke as `global("remote-control-clients")`.

## Verification

- Added transport coverage proving list and revoke work while relay
state is disabled, IDs are escaped, picker-only fields are returned,
timestamps are converted, revoke accepts `204`, auth headers are
forwarded, `401` retries exactly once, `403` is not retried, and
malformed list payloads retain decode context.
- Added an app-server integration test proving both JSON-RPC methods
work before relay enablement and successful revoke returns `{}`.
- Regenerated and validated experimental and standard app-server schema
fixtures.

Allow EDU accounts to fetch cloud config bundles (#25963 )

## Summary

Allow EDU ChatGPT workspaces to fetch cloud config bundles. The existing
cloud config eligibility gate only allowed business-like and enterprise
plans, which meant EDU admins could configure managed policies in the UI
but the Codex client would skip fetching them.

This keeps individual/pro and team-like usage-based plans excluded, and
adds service-level coverage for both `edu` and `education` plan aliases.

## Validation

- `just fmt`
- `just test -p codex-cloud-config`
- Built the Codex app locally, created a new EDU ChatGPT workspace, and
verified config bundles can be fetched and are properly applied.

feat: add extension turn-input contributors (#25959 )

## Disclaimer
Do not use for now

## Why

Extensions can already contribute prompt fragments and request same-turn
item injection, but there was no host-owned hook for contributing
structured `ResponseItem`s while Codex is assembling a new turn's
initial model input. This change adds that seam so extensions can attach
turn-local input that depends on the submitted user input and resolved
turn environments without routing through prompt text or late injection.

## What changed

- add `TurnInputContributor` to `codex_extension_api` and export the new
`TurnInputContext` / `TurnInputEnvironment` types it receives
- teach `ExtensionRegistry` to register and expose turn-input
contributors alongside the existing extension hooks
- call registered turn-input contributors from
`core/src/session/turn.rs` while building the initial injected input for
a turn, then append their returned `ResponseItem`s after the skill and
plugin injections

config: express implicit sandbox defaults as permission profiles (#25926 )

## Why

`PermissionProfile` is becoming the default way to represent Codex
permissions, but the implicit default behavior should stay the same for
now:

- trusted projects use `:workspace`
- untrusted projects also use `:workspace`
- roots without a trust decision use `:read-only`
- unsandboxed Windows falls back to `:read-only`

This keeps the existing sandbox semantics while making silent config
defaults observable as built-in permission profiles instead of treating
the legacy `SandboxPolicy` projection as the primary shape.

## What Changed

- Refactored legacy sandbox derivation to resolve the configured sandbox
mode once, then apply the implicit project fallback only when no sandbox
mode was configured.
- Preserved the existing trust-decision fallback: trusted and untrusted
projects default to workspace-write where supported.
- Added empty-config coverage asserting that an untrusted project
resolves to the built-in active permission profile (`:workspace` outside
unsandboxed Windows).

## Verification

- `just fmt`
- `just test -p codex-core 'config::'`
- `just test -p codex-config`

[codex] Fix Windows BuildBuddy Bazel wrapper execution (#25915 )

## Why

#25156 moved Bazel CI launches into a shared Python wrapper. On Windows,
launching Bazel with `os.execvp` can split the spaced
`--test_env=PATH=...` argument and fail to propagate the eventual Bazel
exit status, allowing jobs to pass without running tests. This reapplies
the wrapper after #25909 with a Windows-safe launch path.

## What changed

Use a waited `subprocess.run` launch on Windows while preserving
`os.execvp` on Unix. Add a process-level regression test for spaced
arguments and child exit status, and run it on Windows Bazel shard 1.

## Experiment

To confirm Bazel was actually invoking tests, patch `87b61d0be6`
temporarily added an intentionally failing `codex-core` unit test. Bazel
failed on that sentinel on all three major platforms:

- [Linux Bazel
test](https://github.com/openai/codex/actions/runs/26841132773/job/79151062486)
- [macOS Bazel
test](https://github.com/openai/codex/actions/runs/26841132773/job/79151062362)
- [Windows Bazel test shard
1/4](https://github.com/openai/codex/actions/runs/26841132773/job/79151062155)

The sentinel was removed after collecting this evidence. Windows Bazel
[clippy](https://github.com/openai/codex/actions/runs/26841132773/job/79151062914)
and [release
verification](https://github.com/openai/codex/actions/runs/26841132773/job/79151062739)
also passed.

## Validation

After removing the sentinel, `just test -p codex-core` no longer
reported it. The local run retained two unrelated environment-specific
failures.

feat: add skills extension scaffold (#25953 )

## Disclaimer
This is only here for iteration purpose! Do not make any code rely on
this

## Why

Skills still live behind `codex-core` discovery and injection paths, but
the extension system needs an authority-aware home before that logic can
move. This adds that boundary without changing current skills behavior,
and keeps host, executor, and remote skills distinct so future
list/read/search flows do not collapse back to ambient local paths.

## What changed

- Add the `codex-skills-extension` workspace/Bazel crate under
`ext/skills`.
- Define the initial catalog, authority, provider, and turn-state types
for authority-bound skill packages and resources.
- Register placeholder thread/config/prompt/turn lifecycle contributors
plus host, executor, and remote provider aggregation points.
- Capture the remaining extraction work as TODOs, including the missing
extension API hooks needed for per-turn catalog construction and typed
skill injection.
- Keep plugins outside the runtime skills model: plugin-installed skills
are treated as materialized host-owned skill sources once available.

## Verification

- Not run locally.

[codex] Publish Python runtime wheels with Python SDK releases (#25906 )

## Summary
- stop publishing Python runtime wheels as a side effect of Rust
releases
- publish runtime wheels from the Python SDK release workflow, either
explicitly before updating the SDK pin or immediately before a
`python-v*` SDK release
- resolve the runtime release from the requested version or the SDK
package's exact `openai-codex-cli-bin` pin
- build two musllinux-tagged wheels from the Rust-release Linux package
archives alongside the six existing runtime wheels
- validate SDK beta tags before any PyPI write

## Release configuration
- update the `openai-codex-cli-bin` PyPI trusted publisher to trust
`.github/workflows/python-sdk-release.yml` and the
`publish-python-runtime` job

## Pin update flow
- run the `python-sdk-release` workflow manually with the new runtime
version before opening or updating the SDK pin PR
- after the pin lands, a `python-v*` SDK tag republishes with
`skip-existing: true` before publishing the SDK package

## Validation
- ran `just fmt`
- validated the edited workflow YAML
- validated the embedded `publish-python-runtime` Bash with `bash -n`
- validated manual `0.136.0 -> rust-v0.136.0` mapping
- validated tag-driven `python-v0.1.0b3 -> 0.132.0 -> rust-v0.132.0`
mapping
- validated rejection of an invalid SDK tag before publication
- confirmed `rust-v0.136.0` contains the two required Linux package
archives
- CI will provide the full test signal

config: remove dead profile sandbox fallback (#25943 )

## Why

`profile_sandbox_mode` was left over from the old selected legacy
profile path. Production now always derives permissions without that
value, and legacy profile contents are ignored, so keeping a parameter
that is always `None` makes `derive_permission_profile` look like it
still supports a fallback that no longer exists.

## What Changed

- Removed the `profile_sandbox_mode` argument from
`ConfigToml::derive_permission_profile`.
- Updated the production caller and legacy sandbox-policy test helper to
match.
- Dropped the stale unselected legacy-profile sandbox test that only
protected the removed fallback shape.

## Verification

- `just test -p codex-config`
- `just test -p codex-core 'config::'`

Add remote request permissions integration coverage (#25867 )

## Stack

1. #25850 - Key request-permission grants by environment: stores and
applies sticky permission grants per environment id.
2. #25858 - Add `environmentId` to `request_permissions`: lets the model
target a selected environment and resolves relative permission paths
against it.
3. #25862 - Propagate permission approval environment id: carries the
selected environment id through approval events, app-server requests,
TUI prompts, and delegate forwarding.
4. This PR (#25867) - Add remote request permissions integration
coverage: verifies the selected remote environment across request,
approval, grant reuse, and exec.

This PR is stacked on #25862 and should be reviewed after #25850,
#25858, and #25862.

## Why

The environment-scoped permission stack needs one end-to-end check that
exercises the CCA-shaped path, not only unit-level parsing. This
verifies that a model-sent `environmentId` on `request_permissions`
reaches the approval event, stores the grant under the selected
environment, and is reused by a later tool call in that same
environment.

## What Changed

- Adds a remote executor integration test for `request_permissions` with
`environmentId: remote` and a relative write root.
- Asserts the permission event reports the remote environment and cwd,
and that the normalized grant resolves under the remote cwd.
- Approves the grant, then runs a remote `exec_command` without explicit
per-call permissions and verifies it completes without another exec
approval and writes only in the remote filesystem.

## Verification

- Not run locally per instruction.
- `git diff --check`

[codex] Keep hosted tools visible in code-only mode (#25890 )

## Why

`code_mode_only` moved ordinary runtime tools behind `exec`, but it also
hid hosted Responses tools. Hosted `web_search` and `image_generation`
do not have a nested `exec` runtime path, so code-only sessions lost
those capabilities entirely even when their existing provider, auth,
model, and configuration gates passed.

## What changed

- Keep hosted Responses tools top-level in `code_mode_only` sessions
after their existing gates pass.
- Preserve the existing nested-tool behavior for ordinary runtimes and
the direct-only behavior for multi-agent v2 tools.
- Add planner coverage for `code_mode_only` with default multi-agent v2
settings, hosted live web search, and hosted image generation.

## Verification

- Added focused regression coverage in
`codex-rs/core/src/tools/spec_plan_tests.rs`.
- Left execution to CI per repository workflow.

core: stop passing legacy SandboxPolicy to guardian reviews (#25911 )

## Why

Guardian review turns already submit a read-only `PermissionProfile`,
which is the permissions model the runtime should honor. Passing the
equivalent legacy `SandboxPolicy` through `ThreadSettingsOverrides`
keeps two representations of the same read-only constraint alive on this
path and makes the guardian flow depend on compatibility plumbing that
is being phased out.

## What Changed

- Set `sandbox_policy` to `None` when the guardian review session
submits its child `Op::UserInput`.
- Keep `permission_profile: Some(PermissionProfile::read_only())` and
`approval_policy: Some(AskForApproval::Never)`, so the guardian review
remains read-only and cannot request approvals.
- Remove the now-unused `SandboxPolicy` import and redundant comment
from `codex-rs/core/src/guardian/review_session.rs`.

## Verification

Not run locally; this is a narrow cleanup of redundant thread-settings
override state.

Switch runtime to cloud config bundle (#24622 )

## Summary

- Adapts the moved `codex-cloud-config` crate from the legacy cloud
requirements endpoint to the new config bundle endpoint.
- Switches runtime consumers from `CloudRequirementsLoader` to
`CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
config and requirements.
- Removes the legacy cloud requirements domain loader path.

## Details

This intentionally keeps `codex-cloud-config` monolithic for review
lineage: the previous PR establishes the crate move, and this PR shows
the behavior change against that moved implementation. A follow-up PR
splits the module back into focused files.

The new bundle path preserves the important cloud requirements loader
semantics where intended: account-scoped signed cache, 30 minute TTL, 5
minute refresh cadence, retry/backoff, auth recovery, and fail-closed
startup loading. The cached payload changes from a single requirements

Populate workspace kind on Codex turn events (#25135 )

## Summary
- carry `workspace_kind` from Responses API client metadata into the
turn resolved analytics fact
- serialize the optional value on `codex_turn_event`
- cover both the turn metadata source and turn event serialization

The `workspace_kind` tells us whether a thread had a project attached vs
projectless. this is an indicator for who is adopting Codex for
knowledge work outside of coding

## Testing
- `env UV_CACHE_DIR=/private/tmp/uv-cache
/private/tmp/cargo-tools/bin/just fmt`
- `env PATH=/private/tmp/cargo-tools/bin:$PATH
CARGO_HOME=/private/tmp/cargo-home UV_CACHE_DIR=/private/tmp/uv-cache
/private/tmp/cargo-tools/bin/just test -p codex-analytics`
- `env PATH=/private/tmp/cargo-tools/bin:$PATH
CARGO_HOME=/private/tmp/cargo-home UV_CACHE_DIR=/private/tmp/uv-cache
/private/tmp/cargo-tools/bin/just test -p codex-core turn_metadata`

Paired with openai/openai#970661, which keeps forwarding the same
metadata key through Responses API headers.

Fix Windows running thread resume path normalization (#25509 )

## Why

Fixes #24944.

On Windows, app-server resume could reject an active running thread when
the requested session path used normal `C:\...` form and the
already-running path used verbatim `\\?\C:\...` form. The paths point at
the same JSONL file, but the resume stale-path guard compared raw
`PathBuf`s, so desktop resume and heartbeat flows could fail with a
mismatched-path error.

## What Changed

- Compare requested and active rollout paths with
`path_utils::paths_match_after_normalization`.
- Extend the existing running-thread mismatched-path test with a
Windows-only same-file resume case before the stale-path rejection.

## Verification

- `just test -p codex-app-server
thread_resume_rejects_mismatched_path_for_running_thread_id`

Use environment secrets for Azure signing (#24859 )

## Summary
- Move Azure Trusted Signing values out of reusable workflow-call
secrets and into the `azure-artifact-signing` environment scope
- Attach the Windows signing job to the `azure-artifact-signing`
environment so it can resolve the signing secrets directly
- Stop inheriting caller secrets for the Windows release reusable
workflow

## Validation
- `git diff --check -- .github/workflows/rust-release.yml

[codex] Pin Python SDK to glibc-compatible runtime (#25907 )

## Summary
- pin the Python SDK runtime package to `openai-codex-cli-bin==0.136.0`
so Ubuntu/glibc installs resolve a compatible wheel
- refresh generated SDK artifacts and lock data for the runtime update
- keep newly generated client-message-id wire models internal to the
generated protocol layer

## Dependency
- merge #25906 first so the Python SDK release publishes both manylinux
and musllinux runtime wheels before publishing the package with this pin

## Validation
- ran `just fmt`
- regenerated the Python public API helpers
- validated the edited workflow YAML
- CI passed 29/29 checks

Propagate permission approval environment id (#25862 )

## Stack

1. #25850 - Key request-permission grants by environment: stores and
applies sticky permission grants per environment id.
2. #25858 - Add `environmentId` to `request_permissions`: lets the model
target a selected environment and resolves relative permission paths
against it.
3. This PR (#25862) - Propagate permission approval environment id:
carries the selected environment id through approval events, app-server
requests, TUI prompts, and delegate forwarding.
4. #25867 - Add remote request permissions integration coverage:
verifies the selected remote environment across request, approval, grant
reuse, and exec.

This PR is stacked on #25858, and #25867 is stacked on this PR.

## Why

PR2 lets the model bind a `request_permissions` call to a selected
environment, but the approval event and client-facing request still
needed to carry that binding. For CCA, the user-facing prompt and
delegated approval path should know which environment the grant applies
to instead of relying on cwd alone.

## What Changed

- Added optional `environmentId` to `RequestPermissionsEvent`.
- Emit the selected environment id from core permission approval events.
- Preserve the environment id through delegate forwarding, including
cwd-based delegated requests.
- Added `environmentId` to app-server permission approval params,
generated schema/TypeScript artifacts, and README examples.
- Preserve and display the environment id in TUI permission approval
prompts.
- Updated focused core, app-server protocol, and TUI conversion
coverage.

## Testing

Fix Windows release PDB staging (#25916 )

## Summary
- Teach the Windows release prebuild staging step to locate Rust/MSVC
PDBs emitted with crate-style underscore names.
- Stage PDBs under the shipped hyphenated binary names so the downstream
symbol archive step keeps the same artifact contract.
- Keep a fallback for already-hyphenated PDB names and fail with a clear
diagnostic if neither form exists.

## Root cause
The recent symbol publishing change in #25649 started copying
`${binary}.pdb` from `target/<triple>/release` during Windows prebuild
staging. Cargo still emits the `.exe` with the hyphenated binary name,
but MSVC PDBs for hyphenated Rust crates are emitted with underscores,
for example `codex_app_server.pdb` for `codex-app-server.exe`. The
release workflow was still building into the expected directory; the new
PDB copy step was looking for the wrong filename.

## Impact
This unblocks the `rust-release` Windows prebuilt-binary jobs for
hyphenated binaries while preserving the hyphenated PDB names consumed
by the final Windows release packaging and symbol archive steps.

## Validation
- `just fmt` from `codex-rs`
- `git diff --check -- .github/workflows/rust-release-windows.yml`
- Parsed `.github/workflows/rust-release-windows.yml` as YAML locally
- Local bash staging sanity test for both underscore-emitted and
hyphenated PDB filenames

Route standalone image generation through host finalization md (#25176 )

## Why

Standalone image-generation extensions emitted turn items through the
low-level event path, bypassing host-owned finalization such as image
persistence and contributor processing. At the same time, the
generated-image save-path hint must remain visible to the model through
the extension tool's `FunctionCallOutput`, rather than the legacy
built-in developer-message path.

## What changed

- Extended `ExtensionTurnItem` to support image-generation items while
keeping the extension-facing emitter API limited to `emit_started` and
`emit_completed`.
- Routed extension completion through core `finalize_turn_item`, so
standalone image-generation items receive host-owned processing and
persisted `saved_path` values before publication.
- Kept legacy built-in image generation on its existing
developer-message hint path, while standalone image generation returns
its deterministic saved-path hint in `FunctionCallOutput`.
- Shared the image artifact path and output-hint formatting used by core
and the image-generation extension.
- Passed thread identity through extension tool calls so standalone
image generation can construct the same intended artifact path as core.
- Added an app-server integration test covering real standalone image
generation, saved artifact publication, model-visible output hint
wiring, and absence of the legacy developer-message hint.

## Validation

- `just fmt`
- `just test -p codex-image-generation-extension`
- `just test -p codex-web-search-extension`
- `just test -p codex-goal-extension`
- `just test -p codex-memories-extension`

Add environmentId to request_permissions (#25858 )

## Stack

1. #25850 - Key request-permission grants by environment: stores and
applies sticky permission grants per environment id.
2. This PR (#25858) - Add `environmentId` to `request_permissions`: lets
the model target a selected environment and resolves relative permission
paths against it.
3. #25862 - Propagate permission approval environment id: carries the
selected environment id through approval events, app-server requests,

4. #25867 - Add remote request permissions integration coverage:
verifies the selected remote environment across request, approval, grant
reuse, and exec.

This PR is stacked on #25850; #25862 and #25867 are stacked on this PR.

## Why

PR1 made request-permission grants internally environment-keyed, but the
model-facing `request_permissions` tool could still only target the
primary environment. For CCA and multi-environment turns, the tool needs
an explicit way to bind a permission request to a selected attached
environment before resolving relative paths.

## What Changed

- Added optional `environmentId` to `RequestPermissionsArgs`, with
`environment_id` accepted as an alias.
- Exposed `environmentId` in the `request_permissions` tool schema and
description.
- Resolve the selected environment before parsing filesystem permission
paths, so relative paths bind to the selected environment cwd.
- Route validated tool calls through
`request_permissions_for_environment` directly instead of duplicating
environment lookup in `Session::request_permissions`.
- Reject unknown environment ids with a model-facing error.
- Updated focused request-permissions and Guardian call sites for the
new optional field.

## Testing

[codex-analytics] Track CodexErr details in turn analytics (#25707 )

## Summary
- add analytics-only `CodexErr` telemetry to `codex_turn_event` while
leaving existing `turn_error` unchanged
- record terminal `CodexErr` facts from core immediately before the
existing turn error event is sent
- emit source-truth `codex_error_*` fields for downstream analytics,
including the raw `CodexErr::InvalidRequest(String)` message as
`codex_error_subreason`

## Validation
- `just test -p codex-analytics`
- attempted `just test -p codex-core`, but the local run timed out
across unrelated integration suites in this environment and is not being
used as validation

Key request-permission grants by environment (#25850 )

## Stack

1. This PR (#25850) - Key request-permission grants by environment:
stores and applies sticky permission grants per environment id.
2. #25858 - Add `environmentId` to `request_permissions`: lets the model
target a selected environment and resolves relative permission paths
against it.
3. #25862 - Propagate permission approval environment id: carries the
selected environment id through approval events, app-server requests,
TUI prompts, and delegate forwarding.
4. #25867 - Add remote request permissions integration coverage:
verifies the selected remote environment across request, approval, grant
reuse, and exec.

#25858, #25862, and #25867 are stacked on this PR and should be reviewed
after it.

## Why

Multi-environment CCA turns can attach both local and remote executors,
but request-permission grants were still effectively cwd-only. Pending
permission requests tracked a cwd, while stored turn/session grants had
no environment identity, so sticky grants could be reused through the
wrong executor context.

This makes the first permission-grant step environment-aware without
changing the external `request_permissions` payload shape: omitted
environment targeting remains bound to the primary turn environment.

## What Changed

- Store turn- and session-scoped request-permission grants by
`environment_id`.
- Keep the selected `TurnEnvironmentSelection` with pending
`request_permissions` calls so approval responses normalize and record
grants against the same environment.
- Resolve relative `request_permissions` file paths against the primary
turn environment cwd instead of deprecated `turn.cwd`.
- Apply sticky grants in `shell`, `exec_command`, and `apply_patch` by
selected environment id while still using the actual tool cwd for
cwd-relative permission materialization.
- Update Guardian and request-permissions coverage for the
environment-keyed grant behavior.

## Testing

Not run locally. Added or updated focused coverage for:

- `request_permission_grants_are_environment_keyed`
-
`request_permissions_tool_resolves_relative_paths_against_primary_environment`
- related Guardian/request-permissions sticky grant tests

[codex] Revert shared BuildBuddy Bazel wrapper (#25909 )

## Why

PR #25905 intentionally adds a failing `codex-core` unit test, but its
[Bazel test on Windows
check](https://github.com/openai/codex/actions/runs/26837526950/job/79135369259)
passed. That shows the Bazel configuration introduced by #25156 is not
behaving as expected, so revert it while the configuration can be
investigated separately.

## What changed

Revert #25156 in full, restoring the previous Bazel remote
configuration, CI scripts, workflows, `rusty_v8` handling, and
documentation. This removes the shared BuildBuddy wrapper and its tests.

## Validation

Not run locally; this exact revert was prioritized for a fast rollback.

core: derive built-in permission profiles from raw policies (#25739 )

## Why

Permission profiles that extend a built-in profile should behave like
other TOML inheritance: parent entries provide defaults, and child keys
override matching fields before the profile is compiled.

That was not true for `:workspace`. Previously, a profile with `extends
= ":workspace"` seeded the compiled runtime
`PermissionProfile::workspace_write()` policy and then appended child
filesystem entries. A child override such as `":tmpdir" = "read"`
therefore left the inherited `":tmpdir" = "write"` entry in the final
policy. Since same-target `write` wins over `read` during runtime
resolution, the child override was ineffective.

This also needs a clear source of truth for the built-in profiles. The
protocol-level sandbox policy constructors now define the raw built-in
filesystem entries, and both `PermissionProfile` presets and
config-profile inheritance derive from those same values.

## What Changed

- Add a canonical `FileSystemSandboxPolicy::read_only()` constructor
while keeping the read-only and workspace-write raw filesystem entries
explicit and independent.
- Derive `PermissionProfile::read_only()` from
`FileSystemSandboxPolicy::read_only()`;
`PermissionProfile::workspace_write()` continues to derive from
`FileSystemSandboxPolicy::workspace_write()`.
- Build extensible `:read-only` and `:workspace` parent profiles by
projecting those canonical sandbox policies into
`PermissionProfileToml`, then merge user overrides at the TOML layer
before compilation.
- Add config parsing support for `:slash_tmp` so the built-in
`:workspace` parent can be expressed in the same TOML-shaped filesystem
table as user profiles.
- Document that `PermissionsToml::resolve_profile()` returns an
already-merged `PermissionProfileToml`, and return that profile directly
after removing the resolved-profile wrapper.
- Extend the config test for `extends = ":workspace"` to assert that
inherited `":slash_tmp" = "write"` is preserved and that a child
`":tmpdir" = "read"` entry replaces the inherited `write` entry.

## Verification

- `just test -p codex-config`
- `just test -p codex-protocol`
- `just test -p codex-core
permissions_profiles_resolve_extends_parent_first_with_child_overrides`
- `just test -p codex-core

- `just test -p codex-core`
  - Result: 2596 passed, 4 failed, 1 timed out.
- The failures were existing sandbox/environment-sensitive tests
unrelated to this permissions change:

Route Bazel CI through shared BuildBuddy remote config wrapper (#25156 )

## Why

Bazel remote configuration was selected in several CI scripts and
workflow steps. That made the BuildBuddy tenant policy easy to duplicate
and harder to audit, especially for fork pull requests that must not use
the OpenAI tenant.

This builds on
[sluongng/buildbuddy-ci-host-routing](https://github.com/openai/codex/compare/main...sluongng:codex:sluongng/buildbuddy-ci-host-routing)
and consolidates the policy in one place.

## What to do if this breaks you

See `codex-rs/docs/bazel.md` for details. TLDR:

1. make a BuildBuddy API key and put it in `~/.bazelrc`
2. if you're an OpenAI employee, add `common
--config=buildbuddy-openai-rbe` to `user.bazelrc` in the repo root

Run `just bazel-test` to ensure it works.

Note that `just bazel-remote-test` no longer exists, you need to select
a remote configuration as documented to use RBE.

## What changed

- Add `.github/scripts/run_bazel_with_buildbuddy.py` as the shared Bazel
wrapper and Python library. It selects the OpenAI host only for trusted
upstream GitHub Actions runs, routes keyed fork runs to the generic
host, and falls back to local Bazel execution when no key is available.
- Move endpoint selection into explicit `.bazelrc` configurations and
update Bazel CI, query helpers, and `rusty_v8` staging to use the shared
policy. Loading-phase target-discovery queries remain local.
- Add wrapper and `rusty_v8` unit coverage, plus `just test-scripts` for
the `.github/scripts` Python tests.
- Document local Bazel usage, `user.bazelrc` setup, BuildBuddy
configurations, and CI behavior in `codex-rs/docs/bazel.md`.

## Validation

- `just test-scripts`
- `bash -n .github/scripts/run-bazel-ci.sh
.github/scripts/run-bazel-query-ci.sh
.github/scripts/run-argument-comment-lint-bazel.sh

Skip startup prewarm when websockets are disabled (#25868 )

## Summary
- skip startup websocket prewarm setup when the model client has
Responses-over-WebSocket disabled
- avoid making HTTP-only sessions build prewarm prompt/tool state that
cannot produce a reusable websocket session

## Why
Recent macOS timing flakes were timing out while waiting for first-turn
events in HTTP-only core tests. Startup prewarm is only useful for
websocket-capable providers, but it was scheduled for every session. For
HTTP-only test providers this added unnecessary async startup work
before the regular turn could reach the mocked response flow.

## Testing

[codex] Use git CLI for Cargo fetches across Rust workflows (#25775 )

## Why
Cargo's libgit2 transport has intermittently failed while fetching git
dependencies with nested submodules.
[#25644](https://github.com/openai/codex/pull/25644) applied
`CARGO_NET_GIT_FETCH_WITH_CLI=true` to the main Rust release build after
macOS SecureTransport/libgit2 failures while cloning `libwebrtc`'s
nested `libyuv` submodule. Similar flakes can affect other Cargo-bearing
Rust jobs.

## What changed
Configure `CARGO_NET_GIT_FETCH_WITH_CLI=true` at workflow scope for the
remaining Cargo-bearing Rust workflows:

- fast Rust CI and `cargo-deny`
- reusable Windows and argument-comment-lint release workflows
- `rusty-v8-release` and `v8-canary` Cargo builds and smoke tests

The full Rust CI, reusable nextest workflow, and primary Rust release
build already had the override. Bazel-only workflows are unchanged
because they use a different dependency fetch path.

## Validation
- Parsed all `.github/workflows/*.yml` files as YAML.
- Scanned Cargo-bearing workflows to confirm they configure
`CARGO_NET_GIT_FETCH_WITH_CLI`.

Run Codex async main on a sized stack (#25847 )

## Why

`Runtime::block_on` executes the top-level future on the caller's OS
thread, not on one of Tokio's worker threads. That matters for the
interactive CLI because the Tokio runtime already configures larger
worker stacks, while the process main thread can still have a smaller
platform default stack.

This showed up as a `/clear` crash on macOS: starting a fresh TUI thread
reloads config, and the stack-heavy TOML deserialization path can
overflow before the new session is actually started.

## What Changed

- Run the regular `arg0_dispatch_or_else` async entrypoint on a named
`codex-main` thread.
- Give that thread the same `TOKIO_WORKER_STACK_SIZE_BYTES` stack budget
already used for Tokio worker threads.
- Keep `Arg0DispatchPaths` and the arg0 alias guard lifetime behavior
the same.
- Resume panics from the spawned main thread so panic behavior is
preserved.

## Verification

- `cargo check -p codex-cli` currently fails because the top-level
CLI/TUI future is not `Send` under the new thread boundary.

flake: Keep plugin test homes alive (#25857 )

## Summary

Keep the full `TestCodex` harness alive in plugin integration tests
instead of returning only the `CodexThread`.

## Why

The helper was moving a temporary `codex_home` into `TestCodex`, then
immediately dropping the harness and returning only the thread. For
plugin MCP tests, the MCP server cwd is inside that temporary home. If
the temp directory is removed while MCP startup is still racing, the
server launch can fail with `No such file or directory`.

Keeping the harness in scope keeps the temp home alive for the test
duration and removes the lifetime race behind the recent
`explicit_plugin_mentions_inject_plugin_guidance` flake.

## Validation

- `just fmt`
- `just test -p codex-core

Reduce stack pressure in session startup and config rebuilds (#25844 )

## Why

`/clear` starts a fresh thread with `InitialHistory::Cleared`, which
re-enters the thread/session startup path. That path now builds large
async futures through `ThreadManagerState::spawn_thread_with_source`,
`Codex::spawn`, and `Session::new`. Separately, TUI config rebuilds for
cwd and permission-profile changes build a similarly heavy
`ConfigBuilder::build()` future inside the app task. In debug and Bazel
runs, those call chains can put enough state on the caller stack to
abort before startup or config refresh completes.

This change keeps the behavior the same while moving the heaviest future
frames off the caller stack.

## What changed

- Box `Codex::spawn(...)` in `codex-rs/core/src/thread_manager.rs`
before awaiting it from `spawn_thread_with_source`.
- Box `Session::new(...)` in `codex-rs/core/src/session/mod.rs` before
awaiting it from `Codex::spawn_internal`.
- Route `ConfigBuilder::build()` through a small `tokio::spawn` helper
in `codex-rs/tui/src/app/config_persistence.rs` so cwd and
permission-profile config rebuilds run on a runtime worker stack while
preserving error context.

## Verification

CI is running on the PR.

No new targeted tests were added. This is a mechanical stack-pressure
reduction that keeps the existing behavior and error propagation intact.

Test runtime selector before first turn (#25724 )

Stack split from #25708. Original PR intentionally left open. This fifth
PR adds coverage that a remotely selected multi-agent runtime is applied
when the model is selected before the first turn.

Test remote multi-agent runtime selector override (#25723 )

Stack split from #25708. Original PR intentionally left open. This
fourth PR adds coverage that remote model multi-agent runtime selectors
override local feature flag defaults.

session: keep startup prewarm aligned with resolved multi-agent runtime (#25841 )

## Why

Follow-up to #25722. Startup prewarm builds a preview `TurnContext`
before the first real turn so it can precompute the initial prompt and
tool surface. After the per-thread runtime work landed, that preview
path still recomputed multi-agent mode from `model_info` and feature
defaults instead of reusing the runtime the session had already resolved
from persisted metadata or inheritance.

That could leave the prewarmed session primed for a different
multi-agent mode than the first real turn, which is especially risky
because collaboration tool exposure depends on
`turn_context.multi_agent_version`.

## What changed

- In the `TurnMultiAgentRuntime::Preview` path, prefer
`Session::multi_agent_version()` when it is already known.
- Only fall back to `model_info.multi_agent_version` and feature
defaults when the session has not resolved a runtime yet.
- Keep preview mode read-only: this still avoids storing a runtime
during startup prewarm.

## Testing

- Not run (small runtime-selection follow-up)

Resolve per-thread multi-agent runtime (#25722 )

Stack split from #25708. Original PR intentionally left open. This third
PR resolves the effective per-thread multi-agent runtime from persisted
metadata, inherited runtime, and current model selection.
