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.
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.
## Why
This is part of the follow-up work from #18178 to make Codex ready for
Clippy's
[`await_holding_lock`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_lock)
/
[`await_holding_invalid_type`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_invalid_type)
lints.
This bottom PR keeps the scope intentionally small:
`NetworkProxyState::record_blocked()` only needs the state write lock
while it mutates the blocked-request ring buffer and counters. The debug
log payload and `BlockedRequestObserver` callback can be produced after
that lock is released.
## What changed
- Copies the blocked-request snapshot values needed for logging while
updating the state.
- Releases the `RwLockWriteGuard` before logging or notifying the
observer.
## Verification
- `cargo test -p codex-network-proxy`

### Why
Remote streamable HTTP MCP needs a transport-shaped executor primitive
before the MCP client can move network I/O to the executor. This layer
keeps the executor unaware of MCP and gives later PRs an ordered
streaming surface for response bodies.
### What
- Add typed `http/request` and `http/request/bodyDelta` protocol
payloads.
- Add executor client helpers for buffered and streamed HTTP responses.
- Route body-delta notifications to request-scoped streams with sequence
validation and cleanup when a stream finishes or is dropped.
- Document the new protocol constants, transport structs, public client
methods, body-stream lifecycle, and request-scoped routing helpers.
- Add in-memory JSON-RPC client coverage for streamed HTTP response-body
notifications, with comments spelling out what the test proves and each
setup/exercise/assert phase.
### Stack
1. #18581 protocol
2. #18582 runner
3. #18583 RMCP client
4. #18584 manager wiring and local/remote coverage
### Verification
- `just fmt`
- `cargo check -p codex-exec-server -p codex-rmcp-client --tests`
- `cargo check -p codex-core --test all` compile-only
- `git diff --check`
- Online full CI is running from the `full-ci` branch, including the
remote Rust test job.

## Why
Codex needs a first-class `amazon-bedrock` model provider so users can
select Bedrock without copying a full provider definition into
`config.toml`. The provider has Codex-owned defaults for the pieces that
should stay consistent across users: the display `name`, Bedrock
`base_url`, and `wire_api`.
At the same time, users still need a way to choose the AWS credential
profile used by their local environment. This change makes
`amazon-bedrock` a partially modifiable built-in provider: code owns the
provider identity and endpoint defaults, while user config can set
`model_providers.amazon-bedrock.aws.profile`.
For example:
```toml
model_provider = "amazon-bedrock"
[model_providers.amazon-bedrock.aws]
profile = "codex-bedrock"
```
## What Changed
- Added `amazon-bedrock` to the built-in model provider map with:
- `name = "Amazon Bedrock"`
- `base_url = "https://bedrock-mantle.us-east-1.api.aws/v1"`
- `wire_api = "responses"`
- Added AWS provider auth config with a profile-only shape:
`model_providers.<id>.aws.profile`.
- Kept AWS auth config restricted to `amazon-bedrock`; custom providers
that set `aws` are rejected.
- Allowed `model_providers.amazon-bedrock` through reserved-provider
validation so it can act as a partial override.
- During config loading, only `aws.profile` is copied from the
user-provided `amazon-bedrock` entry onto the built-in provider. Other
Bedrock provider fields remain hard-coded by the built-in definition.
- Updated the generated config schema for the new provider AWS profile
config.
This PR makes the `/statusline` and `/title` setup UIs share one
preview-value source instead of each surface using its own examples.
Both pickers now render consistent live values when available, and
stable placeholders when they are not. It also resolves live preview
values at the shared preview-item layer, so `/title` preview can use
real runtime values for title-specific cases like status text, task
progress, and project-name fallback behavior.
- Adds a shared preview data model for status surfaces
- Maps status-line items and terminal-title items onto that shared
preview list
- Feeds both setup views from the same chatwidget-derived preview data,
with terminal-title-specific formatting applied before `/title` preview
renders
- Keeps project-root preview aligned with status-line behavior while
project in /title keeps its title fallback/truncation behavior
- Adds snapshot coverage for live-only, hardcoded-only, and mixed cases
Test Steps
- Open Codex TUI and launch `/statusline`.
- Toggle and reorder items, then verify the preview uses current session
values when possible, and placeholder values for missing values (ex: no
thread ID).
- Open `/title` and verify it shows the same normalized values,
including live status/task-progress values when available.
