- Bump @earendil-works/pi-coding-agent 0.83.0 -> 0.84.1 via workspace catalog - Forward model samplingParams through worker provider registration - Stream bash tool output live into the tool block (bashUpdate) - Terminate the tool batch when a permission is denied - Emit sessions.status.changed (generating/idle) on Pi and ACP turn start/end - Ack chat.sendMessage immediately; stream without per-delta DB writes - Track real thinking time (reasoning_time) on Pi and ACP thinking blocks - Show a pending assistant message during worker startup in the chat UI - Add SDD docs for pi-model-sampling-params, pi-worker-bash-streaming, pi-worker-permission-terminate - Add .gitignore entry for local config files Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

Confidence Score: 2/5The PR is not yet safe to merge because ACP sessions can remain stuck as generating, reasoning durations can be incorrect, and malformed sampling JSON fails without visible feedback. ACP lifecycle updates are launched in an order that permits idle-to-generating inversion, ACP reasoning windows retain stale timing state, and the sampling editor renders a different error state from the one validation populates.

### Issue 1
apps/daemon/src/host/acp-provider-execution.ts:170-187
**ACP status updates race**
When an ACP prompt completes or fails before the post-launch status write finishes, `runTurn` writes `idle` before `sendMessage` writes `generating`, leaving both persisted state and the UI stuck in `generating` after the turn has ended.
### Issue 2
apps/daemon/src/host/acp-provider-execution.ts:475-480
**Reasoning window start remains stale**
When one ACP turn emits reasoning, then text or a tool update, and then another reasoning segment, closing the first window leaves `reasoningStartTime` set. The later segment therefore reuses the first segment's start and displays a duration that includes the intervening response or tool activity.
```suggestion
if (reasoningStartTime !== undefined && !reasoningAppeared && mapped.blocks.some((b) => b.type !== "plan")) {
const lastReasoning = [...blocks].reverse().find((b) => b.type === "reasoning_content");
if (lastReasoning && typeof lastReasoning.reasoning_time !== "object") {
lastReasoning.reasoning_time = { start: reasoningStartTime, end: now };
}
reasoningStartTime = undefined;
}
```
### Issue 3
packages/ui/src/components/settings/ModelConfigDialog.tsx:390-396
**Sampling validation error stays hidden**
When a user submits malformed sampling-parameter JSON, validation records `errors.samplingParams`, but the field renders the unrelated `samplingParamsError` state. Saving silently stops without an error border or the validation explanation.
```suggestion
className={errors.samplingParams ? "border-destructive" : ""}
onChange={(e) => setSamplingParamsDraft(e.target.value)}
/>
<p className="text-xs text-muted-foreground">
Arbitrary OpenAI-compatible sampling parameters sent as-is to the provider.
</p>

```
### Issue 4
packages/ui/src/components/settings/ModelConfigDialog.tsx:383-397
**UI layout documentation is missing**
The new sampling-parameter control and pending-assistant-message state change visible UI without the repository-required BEFORE/AFTER ASCII layout blocks, making the structural changes harder to review and maintain.

Pull request overview
This PR bumps @earendil-works/pi-coding-agent from 0.83.0 → 0.84.1 (via the workspace catalog) and bundles several Pi worker + chat-flow improvements: pass-through of arbitrary samplingParams to models, live bash output streaming into the tool block, terminating fully-denied tool batches, an ACP-style fire-and-forget turn with sessions.status.changed events, non-blocking snapshot persistence, and accurate "thinking time" stamping for both the Pi worker and ACP.
Changes:
- Pi 0.84.1 catalog bump plus new protocol events (
thinkingStart/End,bashUpdate,settled.messageTimestamp,samplingParams). - Chat responsiveness: immediate ack, session
generating/idlestatus emission, and streaming decoupled from per-delta SQLite writes. - Real reasoning-time computation on thinking/reasoning blocks (Pi + ACP) and a new "Sampling Parameters (JSON)" UI field, with SDD docs, a new pi-update skill, and test updates.

validator to require a parsed value that is non-null, non-array, and
object-shaped before accepting it; retain the existing invalid-JSON error
behavior. Store the validation message under the samplingParamsError state key
consumed by the textarea, and apply the same object-shape validation before
assigning parsedSamplingParams in handleSave.
- Around line 121-125: Update the sampling-parameter draft initialization in
ModelConfigDialog to distinguish an absent value from an explicitly provided
empty object: check only whether modelConfig.samplingParams is undefined, and
stringify {} as "{}" so saving preserves the explicit override instead of
writing undefined. Keep the existing empty-draft behavior for undefined sampling
parameters.

Set the reasoning window end time when the thought stream ends. AcpProviderExecutionPort.runTurn() already keeps the first mapped.reasoningStartTime per turn. However, emitAsText() initializes reasoning_time for every chunk, so the close logic never updates end. Set reasoning_time.end when a non-reasoning update or turn end closes the stream. Add an assertion for two thought chunks.

In `@packages/acp-runtime/src/protocol/acpContentMapper.ts` around lines 73 - 81,
Update emitAsText and the reasoning-stream close handling so reasoning_time.end
is recorded when a non-reasoning update or turn end closes the stream, while
preserving the first reasoningStartTime for the turn. Add or update coverage
asserting that two thought chunks produce one reasoning window with both start
and end times.
- ACP: persist "generating" before launching the turn so a fast turn cannot overwrite the final idle state; clear reasoningStartTime after closing a reasoning interval; drop dead reasoningStarted/reasoningEnded mapper state - Pi: reject the turn when finalizeAssistantMessage fails so the detached completion handler resolves; bashUpdate fallback selects the most recent loading tool block; reset lastAssistantTimestamp per command/settlement - repo: store generation status in a dedicated generation_status column so it never clobbers the 'active' selected-session marker; surface it on reads - UI: validate samplingParams is a JSON object, surface validation errors on the field, and preserve an explicit empty object - tests: reload presenter to verify disk persistence; assert ACP reasoning windows carry start/end; update fake DB for the new column - docs: add text language identifiers to data-flow fences; note behavioral regression coverage for permission terminate and bash streaming Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

Each update to "samplingParamsError" redraws your component for nothing because this useState is set but never shown on screen.
Fix → Use useRef instead of useState when the value is only set and never shown on screen. ref.current = ... updates it without redrawing the component.

@earendil-works/pi-coding-agentfrom 0.83.0 → 0.84.1 (workspace catalog) and bundles a set of Pi worker + chat flow fixes:samplingParamspassthrough for models, livebashoutput streaming into the tool block, and terminating blocked tool batches on permission denial.chat.sendMessagenow acks immediately (fire-and-forget turn like ACP),sessions.status.changed(generating/idle) is emitted on Pi and ACP turn start/end, streaming no longer blocks on per-delta SQLite writes, and the UI shows a pending assistant message during worker startup.reasoning_timeis now stamped on thinking blocks for both the Pi worker (thinking start/end events) and ACP (agent_thought_chunkwindow), so "Thinking for 0ms" is fixed and the header shows an accurate ticking duration.Includes SDD docs for the three Pi features and test updates (sampling params round-trip, worker timeout bump).
