## What changed

Add the `› ` prefix to pinned prompt headers, using bold red for spoken prompts and bold dim styling for other prompts. Reserve one column when truncating the header.

## Testing

Add a rendering test comparing pinned headers with the original prompt rows for both regular and spoken prompts. Update snapshots for the prefix and display-width truncation.

Let task titles use the space previously reserved for the `current` badge
in the agents overview. Update the overview assertion and rendering
snapshots to match.

## Why

Guardian reviews need to retain original evidence across parent compaction when checkpoint reuse is disabled, including after resume and rollback.

## What changed

- Make disabling `guardian_reuse_parent_compaction` select a bounded, independent review transcript while preserving thread-owned authorization.
- Keep synchronous reviews and asynchronous scoring independent of parent checkpoints, and allow reviewer sessions to continue using transcript deltas across parent compaction.
- Persist transcript entries with rollback provenance while remaining compatible with older checkpoint readers and metadata-free checkpoints.
- Exclude compaction output from the transcript and synthetic summaries from rollback turn boundaries. Use acceptance ordering to remove rolled-back evidence even when persistence order differs.

## Testing

Add regression coverage for reviewer continuity, evidence retention across compaction and resume, rollback after local and remote compaction, and checkpoint serialization compatibility.

## Why

Inspecting one MCP server should not require full-inventory discovery or a separate connection when a thread already has one.

## What changed

- Add optional `serverName` to `mcpServerStatus/list` and update generated schemas and bindings.
- With `threadId`, apply any pending runtime refresh and reuse the thread's current connection and tool catalog, waiting only for the selected server during discovery.
- Without `threadId`, create a discovery connection for only the selected server. Unknown names return an empty page; omitting `serverName` preserves full-inventory discovery.

## Testing

Add a regression test covering both status detail modes, checking that tool metadata is preserved and that status reads do not repeat `initialize` or `tools/list` requests.

…ns (#48796)

## Why

Guardian denial-limit interruptions lack a structured error identifying the cause. Make this opt-in because older clients may not recognize the new error in shared history.

## What changed

- Add `auto_review.circuit_break_action = "strict"` to attach `TooManyDenials` to the interrupted turn. The default leaves the error unset.
- Expose `turn.error.codexErrorInfo = "tooManyDenials"` in app-server notifications and saved history, and update protocol schemas and generated types.
- Preserve the warning, denial limit, and interrupted status without emitting a separate error notification.

## Testing

Add an integration test covering omitted, `default`, and `strict` settings, checking warnings, live turn errors, the absence of separate error notifications, and persisted turn errors after restart.

## Why

Some Windows terminals send legacy mouse reports as key records. Requesting SGR reports lets ConPTY translate them into mouse records.

## What changed

Write and flush the SGR encoding request separately from `EnablePointerCapture`, so it also reaches terminals when capture uses the Windows console API. Explicitly reset SGR encoding during Windows mouse cleanup, even if restoring the console mode fails.

## Testing

Add regression tests for cleanup after SGR setup fails and an isolated Windows console test that checks mouse input activation, SGR encoding, and restoration of the original console mode and default encoding.

## What changed

Render ordered list markers in the TUI with the terminal's `LightBlue` color instead of `accent_color()`.

## Testing

Add a snapshot covering ordered list markers alongside links and inline code. Update rendering expectations and nested-list streaming tests to assert `LightBlue`, including the incremental rendering snapshot.

## Why

The “Implement this plan?” prompt blocked transcript scrolling, preventing users from reviewing earlier steps in a long plan while deciding how to proceed.

## What changed

Allow mouse-wheel scrolling over the visible transcript while a modal is active. Keep keyboard input with the modal and preserve restrictions on transcript selection, scrolling outside the transcript, and scrolling with completion popups open.

## Testing

Add input tests and a snapshot covering plan-prompt scrolling, keyboard navigation, dismissal and submission, pointer boundaries, and completion-popup behavior.

## Why

Completion footers hid known durations unless they exceeded 60 seconds, leaving short turns without elapsed-time information.

## What changed

Show all known durations for live and restored turns, rendering sub-second durations as `Worked for <1s`. Separate completion metadata with `•` instead of `·`.

## Testing

Update live completion, history replay, and separator tests to cover short durations, missing timestamps, and the revised footer format. Refresh affected TUI snapshots.

GitOrigin-RevId: 666e765db5426c5f9cc00d73f71cab649ad34947
## What changed

- Add `CodexThread::prewarm_with_history()` to prepare a WebSocket response with existing conversation history and executed-tool metadata using `generate: false`. The next turn can reuse the prepared response when its prompt extends that history and request settings match.
- Keep startup prewarming and `prewarm()` on the existing empty-input path, and skip preparation when the cached WebSocket is ready.
- Label prewarm telemetry by input mode and WebSocket continuation metrics with `after_prewarm`.
- Rename `persistent_mode_enabled` to `persistent_execution_enabled` without changing its behavior.

## Testing

Extend WebSocket coverage to check history preservation during reconnect prewarming, reuse of the prepared response on the next turn, and omission of `previous_response_id` for a non-prefix prompt.

## Why

Splitting every statement at semicolons and rejecting label punctuation prevents rendering labels such as `A["Go []; &"]`, sequence messages containing `data[0] = {x: 1}`, and class members containing semicolons.

## What changed

- Split statements using diagram-specific rules, preserving semicolons inside flowchart labels, quoted tokens, and class member lines. Sequence quotes remain literal text.
- Respect quoted flowchart label delimiters and allow printable label punctuation, including literal ampersands and comparison operators.
- Reject unsupported entity escapes before statement splitting can truncate them, while retaining rejection of HTML markup and malformed labels.
- Document the supported syntax and require newlines between class members.

## Testing

Add parser assertions and update rendering snapshots for punctuation, quoted delimiters, and semicolons. Extend rejection coverage for entity escapes across diagram families, malformed quotes, and invalid class bodies.

## What changed

- Give tool fragment sizes and namespace counts logarithmic boundaries through 32,768.
- Give enabled and kept skill counts integer boundaries from 0 through 512, removed description characters logarithmic boundaries through 131,072, and skill truncation flags boundaries at 0 and 1.
- Record these metrics with explicit boundaries, separating zero values and retaining overflow buckets above each range.

## Testing

Extend tool and skill metric tests to assert explicit boundaries. Add an export test covering zero, one, the upper boundary, and overflow, including bucket counts, ordering, and sample totals.

## Why

Capture jitter and mute transitions can shift RTP timestamps off the 20 ms source grid, causing receivers that assemble fixed-duration frames to reject subsequent audio.

## What changed

Advance elapsed gaps in whole 20 ms packets and keep the track clock on that grid. Bias empty gap durations by 1 ns to avoid losing an RTP tick to floating-point truncation.

## Testing

Update jitter and mute tests to assert exact clock advancement, including a 580 ms gap, and verify that resumed RTP timestamps stay aligned to 960-sample packets.

## What changed

- Show a hand pointer over actionable transcript links while Codex captures mouse input in Ghostty and Kitty, excluding sessions inside terminal multiplexers.
- Share link hit testing between hover and click activation, and refresh hover after rendering so scrolling and live output cannot leave a stale hand pointer.
- Suppress link hover during mouse presses and drags, overlays, and popups, and clear remembered mouse coordinates on focus loss, resize, and resume.
- Restore the terminal's pointer policy when releasing mouse capture, releasing Kitty's override and using a text pointer in Ghostty. Deduplicate pointer updates and preserve cleanup after write failures.

## Testing

Add tests for wrapped links containing wide characters, hover/click target agreement, scrolling, pointer transitions and restoration, write-failure retries, and hover invalidation.

## Why

Fresh threads have no rollout until their first turn, so archiving them previously failed with a missing-rollout error.

## What changed

Persist loaded, non-ephemeral threads before looking them up for archival. This lets a newly started thread be archived without creating a user turn.

## Testing

Update the archive regression test to cover threads with no turns in both legacy and paginated history modes. Verify the archive notification, empty turn history, `NotLoaded` status, and archived rollout path.

## Why

Allow the provisioning service time to start without holding up desktop readiness checks for the full provisioning timeout.

## What changed

- Poll service status while startup is pending, waiting up to five seconds within the caller's deadline. Treat absent, deletion-pending, or other non-running service states as unavailable.
- Preserve the original provisioning deadline for pipe availability and request processing, and reject requests whose deadline expires during server authentication.
- Recheck service status when the pipe disappears while waiting for an available instance.

## What changed

Render interrupted turns with secondary text styling and shorter wording,
removing the suggestion to tell the model what to do differently.

## Testing

Update interruption snapshots and assert that the notice uses secondary text
styling.
