https://github.com/openai/codex/pull/3062 added `windows-11-arm` to the
list of images used for building, but the job to build an alpha just
failed:
https://github.com/openai/codex/actions/runs/17415565601
with this error:

so allegedly this should fix it? I'm surprised this was not necessary
for the `windows-latest` image, though.
Fixes excessive blank lines appearing during agent message streaming.
- Only insert a separator blank line for new, non-streaming history
cells.
- Streaming continuations now append without adding a spacer,
eliminating extra gaps between chunks.
Affected area: TUI display of agent messages (tui/src/app.rs).
3 quick fixes to docs/config.md
- Fix the reference table so option lists render correctly
- Corrected the default `stream_max_retries` to 5 (Old: 10)
- Update example approval_policy to untrusted (Old: unless-allow-listed)
This is in support of https://github.com/openai/codex/issues/2979.
Once we have a release out, we can update the npm module and the VS Code
extension to take advantage of this.
Hide the “/init” suggestion in the new-session banner when an
`AGENTS.md` exists anywhere from the repo root down to the current
working directory.
Changes
- Conditional suggestion: use `discover_project_doc_paths(config)` to
suppress `/init` when agents docs are present.
- TUI style cleanup: switch banner construction to `Stylize` helpers
(`.bold()`, `.dim()`, `.into()`), avoiding `Span::styled`/`Span::raw`.
- Fixture update: remove `/init` line in
`tui/tests/fixtures/ideal-binary-response.txt` to match the new banner.
Validation
- Ran formatting and scoped lint fixes: `just fmt` and `just fix -p
codex-tui`.
- Tests: `cargo test -p codex-tui` passed (`176 passed, 0 failed`).
Notes
- No change to the `/init` command itself; only the welcome banner now
adapts based on presence of `AGENTS.md`.
we were checking every typed character to see if it was an image. this
involved going to disk, which was slow.
this was a bad interaction between image paste support and burst-paste
detection.

## Summary
Pressing Enter with an empty composer was treated as a submission, which
queued a blank message while a task was running. This PR suppresses
submission when there is no text and no attachments.
## Root Cause
- ChatComposer returned Submitted even when the trimmed text was empty.
ChatWidget then queued it during a running task, leading to an empty
item appearing in the queued list and being popped later with no effect.
## Changes
- ChatComposer Enter handling: if trimmed text is empty and there are no
attached images, return None instead of Submitted.
- No changes to ChatWidget; behavior naturally stops queuing blanks at
the source.
## Code Paths
- Modified: `tui/src/bottom_pane/chat_composer.rs`
- Tests added:
- `tui/src/bottom_pane/chat_composer.rs`: `empty_enter_returns_none`
- `tui/src/chatwidget/tests.rs`:
`empty_enter_during_task_does_not_queue`

#2747 encouraged me to audit our codebase for similar issues, as now I
am particularly suspicious that our flaky tests are due to a racy
deadlock.
I asked Codex to audit our code, and one of its suggestions was this:
> **High-Risk Patterns**
>
> All `send_*` methods await on a bounded
`mpsc::Sender<OutgoingMessage>`. If the writer blocks, the channel fills
and the processor task blocks on send, stops draining incoming requests,
and stdin reader eventually blocks on its send. This creates a
backpressure deadlock cycle across the three tasks.
>
> **Recommendations**
> * Server outgoing path: break the backpressure cycle
> * Option A (minimal risk): Change `OutgoingMessageSender` to use an
unbounded channel to decouple producer from stdout. Add rate logging so
floods are visible.
> * Option B (bounded + drop policy): Change `send_*` to try_send and
drop messages (or coalesce) when the queue is full, logging a warning.
This prevents processor stalls at the cost of losing messages under
extreme backpressure.
> * Option C (two-stage buffer): Keep bounded channel, but have a
dedicated “egress” task that drains an unbounded internal queue, writing
to stdout with retries and a shutdown timeout. This centralizes
backpressure policy.
So this PR is Option A.
Indeed, we previously used a bounded channel with a capacity of `128`,
but as we discovered recently with #2776, there are certainly cases
where we can get flooded with events.
That said, `test_shell_command_approval_triggers_elicitation` just
failed one one build when I put up this PR, so clearly we are not out of
the woods yet...
**Update:** I think I found the true source of the deadlock! See
https://github.com/openai/codex/pull/2876
Today we had a breakage in the release build that went unnoticed by CI.
Here is what happened:
- https://github.com/openai/codex/pull/2242 originally added some logic
to do release builds to prevent this from happening
- https://github.com/openai/codex/pull/2276 undid that change to try to
speed things up by removing the step to build all the individual crates
in release mode, assuming the `cargo check` call was sufficient
coverage, which it would have been, had it specified `--profile`
This PR adds `--profile` to the `cargo check` step so we should get the
desired coverage from our build matrix.
Indeed, enabling this in our CI uncovered a warning that is only present
in release mode that was going unnoticed.
The default install command causes unexpected code to be executed:
```
npm install -g @openai/codex # Alternatively: `brew install codex`
```
The problem is some environment will treat # as literal string, not
start of comment. Therefore the user will execute this instead (because
it's in backtick)
```
brew install codex
```
And then the npm command will error (because it's trying to install
package #)
