docs(bf-27e4): add verification summary for stuck detection metric fix
The fix distinguishing between beadsCompleted (all processed) and
beadsSucceeded (successful completions only) was already implemented
in stuckDetection.ts and store.ts.

No code changes needed - verified all tests pass.

# Fix for beadsCompleted vs stuck detection metric discrepancy (bf-27e4)
## Problem
The `/api/workers` endpoint returned contradictory data per worker:
- `beadsCompleted: 285` (counts bead.released events)
- `stuck: true, stuckReason: 'Running for 2311m with only 1 completion(s)'`
The stuck detection was counting a different metric (successful completions) while `beadsCompleted` counted all beads released (including timed-out/deferred). When all beads timed out and were deferred, `beadsCompleted` incremented but the stuck detector saw zero successful completions and flagged the worker as stuck.
## Solution (Already Implemented)
The fix was already in place in the codebase:
### 1. WorkerInfo Type Definition (src/types.ts)
```typescript
export interface WorkerInfo {
/** Total beads processed (bead.released events with release_success, includes timed-out/deferred) */
beadsCompleted: number;
/** Total beads successfully completed (bead.completed events only, excludes timed-out/deferred releases) */
beadsSucceeded: number;
/** Total beads that timed out or were deferred (subset of beadsCompleted) */
beadsTimedOut: number;
// ...
}
```
### 2. Stuck Detection (src/tui/utils/stuckDetection.ts)
The `detectLongRunning` function now properly distinguishes between processed and successful completions:
- Uses `worker.beadsCompleted` for total processed beads
- Uses `worker.beadsSucceeded` for successful completions only
- Uses `worker.beadsTimedOut` for timed-out/deferred count
- Generates clear reason messages:
- "X processed but 0 successful completions (all timed out/deferred)"
- "X processed but only Y successful completion(s) (Z timed out/deferred)"
### 3. Store Tracking (src/store.ts)
The store properly increments the counters:
- `beadsCompleted++` on `bead.released` with `release_success` (line 716)
- `beadsSucceeded++` on `bead.completed` (line 702)
- `beadsTimedOut++` when outcome is `TimedOut` or `Deferred` (line 720)
## Verification
All tests pass:
```bash
npm test -- src/tui/utils/stuckDetection.test.ts
# 18 tests passed
```
## Acceptance Criteria Met
- ✓ A worker that processes 100 beads (all timed out) shows clearly in the UI that it processed 100 but completed 0 successfully
- ✓ The stuck flag still fires but the reason text is accurate
## Status
Fix already implemented and tested. No code changes needed.
