## Summary
- Add the missing `background_task_id: None` field to the
`AgentIdentityAuthRecord` fixture introduced in `auth_tests.rs`.
## Why
- Current `main` fails Bazel/rust-ci compile paths after the
background-task auth field landed and a later auth test fixture
constructed `AgentIdentityAuthRecord` without that new field.
- I intentionally removed the earlier broader CI-stability edits from
this PR. The code-mode timeout, external-agent migration snapshot, and
MCP resource timeout failures appear to be general/flaky or unrelated to
the agent identity merge stack rather than cleanly caused by it.
## Validation
- `cargo test -p codex-login
dummy_chatgpt_auth_does_not_create_cwd_auth_json_when_identity_is_set --
--nocapture`
- `just fmt`
Follow-up to https://github.com/openai/codex/pull/18178, where we said the await-holding clippy rule would be enabled separately.
Enable `await_holding_lock` and `await_holding_invalid_type` after the preceding commits fixed or explicitly documented the current offenders.
## Problem
The TUI still imported path utilities and config-loader symbols through
app-server-client's legacy_core facade even though those APIs already
exist in utility/config crates. This is part of our ongoing effort to
whittle away at these old dependencies.
## Solution
Rewire imports to avoid the TUI directly importing from the core crate
and instead import from common lower-level crates. This PR doesn't
include any functional changes; it's just a simple rewiring.
Wires patch_updated events through app_server. These events are parsed
and streamed while apply_patch is being written by the model. Also adds 500ms of buffering to the patch_updated events in the diff_consumer.
The eventual goal is to use this to display better progress indicators in
the codex app.
- Replace the active models-manager catalog with the deleted core
catalog contents.
- Replace stale hardcoded test model slugs with current bundled model
slugs.
- Keep this as a stacked change on top of the cleanup PR.
This is the second cleanup in the await-holding lint stack. The
higher-level goal, following https://github.com/openai/codex/pull/18178
and https://github.com/openai/codex/pull/18398, is to enable Clippy
coverage for guards held across `.await` points without carrying broad
suppressions.
The stack is working toward enabling Clippy's
[`await_holding_lock`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_lock)
lint and the configurable
[`await_holding_invalid_type`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_invalid_type)
lint for Tokio guard types.
Several existing fields used `tokio::sync::Mutex<()>` only as
one-at-a-time async gates. Those guards intentionally lived across
`.await` while an operation was serialized. A mutex over `()` suggests
protected data and trips the await-holding lint shape; a single-permit
`tokio::sync::Semaphore` expresses the intended serialization directly.
## What changed
- Replace `Mutex<()>` serialization gates with `Semaphore::new(1)` for
agent identity ensure, exec policy updates, guardian review session
reuse, plugin remote sync, managed network proxy refresh, auth token
refresh, and RMCP session recovery.
- Update call sites from `lock().await` / `try_lock()` to
`acquire().await` / `try_acquire()`.
- Map closed-semaphore errors into the existing local error types, even
though these semaphores are owned for the lifetime of their managers.
- Update session test builders for the new
`managed_network_proxy_refresh_lock` type.
## Verification
- The split stack was verified at the final lint-enabling head with
`just clippy`.

## Why
`PermissionProfile` needs stable, canonical file-system semantics before
it can become the primary runtime permissions abstraction. Without a
canonical form, callers have to keep re-deriving legacy sandbox maps and
profile comparisons remain lossy or order-dependent.
## What changed
This adds canonicalization helpers for `FileSystemPermissions` and
`PermissionProfile`, expands special paths into explicit sandbox
entries, and updates permission request/conversion paths to consume
those canonical entries. It also tightens the legacy bridge so root-wide
write profiles with narrower carveouts are not silently projected as
full-disk legacy access.
## Verification

- Migrates unloaded `thread/name/set` and `thread/memoryModeSet`
app-server writes behind the generic
`ThreadStore::update_thread_metadata` API rather than adding one-off
store methods for setting thread name or memory mode.
- Implements the local ThreadStore metadata patch path for thread name
and memory mode, including rollout append, legacy name index updates,
SessionMeta validation/update, SQLite reconciliation, and re-reading the
stored thread.
- Adds focused local thread-store unit coverage plus app-server
integration coverage for the migrated unloaded write paths.
