When the proxy SSE stream ends without sending a done or error
terminal event, streamProxy now throws an error instead of silently
calling stream.end() with no arguments. The thrown error is caught by
the existing catch block, which pushes an error event with
stopReason='error' and resolves finalResultPromise.
Previously, server disconnects produced a silent success: the stream
iterator completed normally with stopReason='stop' (the default) and
empty content, and finalResultPromise never resolved, causing
callers that awaited stream.result() to hang indefinitely.
This matches the pattern used by the codex provider
(openai-codex-responses.ts) which already guards against missing
terminal events.
Tests assert that streamProxy emits an error event when the SSE
stream ends without a done/error terminal event. Currently failing
because streamProxy silently ends the stream with stopReason='stop'
and empty content.
- Increased `Bun.sleep` delays in TUI tests from short frame intervals to 40ms.
- Adjusted mocked `performance.now` tick advances from 20ms to 40ms so render throttling sees full frame gaps.
- Modified the streaming scrollback settle helper to yield a `nextTick` before sleeping, then flush.
- Added a `showHeader` option to shell rendering and suppressed the bash frame title bar by default.
- Parsed trailing raw-output artifact notices and folded their IDs into status footer metadata instead of command output.
- Updated read-group rendering to use the enabled success mark and omitted duplicate success marks on child files in grouped reads.
- Adjusted find and search renderers to apply tool-title coloring, search icons, and padded layout via createCachedComponent.
- Added tests covering read-group success marking and padded find/search renderer output.
- Added `display.smoothStreaming` to settings schema.
- Updated streaming-reveal behavior to produce smooth 30 FPS reveals.
- Updated event-controller flow to support smooth streaming reveal mode.
- Expanded streaming-reveal tests for the new smooth streaming behavior.
- Constrained the no-append repaint optimization to execute only when the logical viewport position was unchanged.
- Documented the live-region pinned repaint cursor re-anchoring fix in the TUI changelog entry.
Only mark Zod and JSON Schema validation issues as union-branch when their own path matches the combinator's path so nested array fields inside a tag-selected branch keep their singleton-wrap repair.
Fixes#2026
- Updated key canonicalization in keybinding parsing to parse modifiers case-insensitively and infer `shift` from printable uppercase keys.
- Added regression tests for `shift+a` matching uppercase `A` and for cursor anchoring during no-append live repaint scenarios.
- Recorded the uppercase Shift keybinding fix in the package changelog entry.
- Removed Opus-specific `tool_choice.disable_parallel_tool_use` injection for Anthropic tool calls.
- Removed the obsolete `disablesParallelToolUse` helper from model capability checks.
Marked JSON Schema validation issues that come from a failed anyOf/oneOf branch and threaded the marker through the coercion bridge so the singleton-array wrap mirrors the Zod branch guard.
Fixes#2026

- Optimized key matching by canonicalizing key IDs and precomputing alias sets.
- Added prepared-line caching and bounded terminal/width scans to reduce repaint overhead.
Skipped singleton array wrapping for expectations that come only from failed Zod union branches so other branch coercions can succeed first.
Fixes#2026
Wrapped non-string singleton values when an array field is expected so malformed Anthropic-compatible tool calls can validate instead of looping on errors.
Fixes#2026
- Updated `appendRawHttpRequestDumpFor400` to skip execution in the Bun test runtime.
- Imported `isBunTestRuntime` and used it to avoid writing 400 raw request dumps to `~/.omp/logs/http-400-requests` when tests use mocked fetch responses.
- Documented the test-runtime persistence fix in the package changelog.

- Updated task call and result rendering to process shared context with the Markdown renderer, so context sections are now displayed with proper Markdown formatting.
- Stopped shimmer animation on pending bash/eval/task blocks once async state is `running`, preventing the committed frame from freezing a transient dark border segment.

- Preserved ED3 streaming scrollback accounting during capped streaming frames and added tests to prevent committed prefix duplication across terminal history rewrites.
- Added tests confirming `Markdown.render` returns caller-owned lines so per-instance mutations do not change the next render output.
- Added coverage that mutating one instance's render output cannot leak injected lines into another instance via shared cache reuse.
- Added a repeated mutate-then-render test to ensure no line accumulation across multiple render cycles.
- Replaced the repaint viewport clamp with strict bottom anchoring at lines.length - height.
- Removed the anti-duplication clamping path that could persist off-tail #viewportTopRow values between frames.
- Kept native scrollback cleanup to the existing dirty checkpoint mechanism for stale committed prefixes.
- Added `EventLoopKeepalive` in `instrumentedCompleteSimple` to keep the event loop alive during oneshot completion calls.
- This prevented long-lived completion promises from freezing host spinners in Bun by keeping timer servicing active.
- Marked Markdown cached lines as readonly snapshots and returned copied arrays from `render()`.

- Passed a formatted TTSR match message into the agent abort call when streaming is interrupted by TTSR rules.
- Added a `#formatTtsrAbortReason` helper to include matched rule names in the abort reason.
- Added a concurrent-session test confirming aborted tool results mention the matched TTSR rule instead of `Request was aborted`.

- Added `Editor.pasteText()` and OSC5522 disable sequencing on terminal cleanup.
- Replaced the inline todo-phase preview loop in todoToolRenderer with renderTreeList.

- Fixed tab and OSC66 width parsing with `s=`/`w=` metadata handling.
- Added ASCII and long-string fast paths in `visibleWidth` for faster width checks.
- Consolidated visible-width regression coverage by replacing removed IME/Arabic/Jamo tests with `visible-width.test.ts`.
- Added optional `reason` parameters to `Agent.abort` and `AgentSession.abort` APIs.

- Renamed allowUnknownViewportMutation to allowUnknownViewportTransientRepaint to clarify it never authorizes a settled transcript commit.
- Adjusted tool-execution rendering to apply state-based background tinting and spacing for non-framed outputs.
- Detected framed block children and skipped extra padding and tinting so those custom renderers stay flush.
- Wrapped framed output with markFramedBlockComponent so self-framed blocks are recognized by the renderer.
