## Fixed Issues
| Issue | File:Line | Commit |
|-------|-----------|--------|
| Missing closingRef guard after getSize await | src/cli/dashboard/use-task-output-stream.ts:397 | 6ee8f6d |
| Module header exports list not updated | src/cli/dashboard/use-task-output-stream.ts:6 | 6ee8f6d |
| fetchTask nesting depth = 5 levels (trySizeProbe extraction) | src/cli/dashboard/use-task-output-stream.ts:392 | 6ee8f6d, 87a9b67 |
| codePointLength ASCII fast-path | src/cli/dashboard/use-task-output-stream.ts:109 | 6ee8f6d |
| T20 test duplicates production control flow | tests/unit/cli/dashboard/use-task-output-stream.test.ts:467 | 87a9b67 |
| T17-T19 mislabeled (renamed + added probe tests) | tests/unit/cli/dashboard/use-task-output-stream.test.ts:434 | 87a9b67 |
| Inconsistent STREAM_INITIAL naming | tests/unit/cli/dashboard/use-task-output-stream.test.ts:424 | 87a9b67 |
| Stale getByteSize in OutputRepository stubs (4 locations) | tests/fixtures/eval-test-helpers.ts + 2 test files | 6ee8f6d |

## Simplification Pass
| Issue | File | Commit |
|-------|------|--------|
| Redundant inline comment restating JSDoc | src/cli/dashboard/use-task-output-stream.ts | 213978f |
| Bogus TaskOutput stub fields (byteSize/truncated) | tests/fixtures/eval-test-helpers.ts | 213978f |
| Bogus TaskOutput stub fields (byteSize/truncated) | tests/unit/services/agent-exit-condition-evaluator.test.ts | 213978f |

## Fixed (Deferred → Fixed, task-2026-05-01_impl)
| Issue | File:Line | Commit |
|-------|-----------|--------|
| Duplicated streamsRef.current.get fallback pattern (5x) | src/cli/dashboard/use-task-output-stream.ts | 60168a9 — extract getPrev helper |
| output.stdout.join('') creates full copy on change ticks | src/cli/dashboard/use-task-output-stream.ts:190 | perf commit — computeDelta per-chunk |
| fetchAllData 167 lines with 8+ responsibilities | src/cli/dashboard/use-dashboard-data.ts:132 | refactor commit — extract computeOrchestrationLiveness |

## Closed — by design (task-2026-05-01_impl)
| Issue | File:Line | Rationale |
|-------|-----------|-----------|
| useTaskOutputStream hook complexity (7+ refs) | src/cli/dashboard/use-task-output-stream.ts:299 | After getPrev + computeDelta fixes, 0 duplicated patterns remain. The 8 refs each serve a distinct purpose in the React polling pattern (render avoidance, interval stability, unmount safety, change detection, terminal tracking). Grouping would be cosmetic indirection with no behavioral benefit. |
| SELECT * in getStmt loads all columns | src/implementations/output-repository.ts:50 | get() returns TaskOutput — all columns are needed. getSize() probe already avoids get() when output is unchanged. Replacing SELECT * adds maintenance burden (must update query when columns change) with zero perf benefit on single-row PK lookups. |

## Deferred (Pre-existing / Architectural — Future PR)
| Issue | File:Line | Reason |
|-------|-----------|--------|
| getSize probe still joins full stdout when size changed | src/cli/dashboard/use-task-output-stream.ts:190 | Diminishing returns — probe already handles the critical OOM case (idle tasks). computeDelta mitigates the join cost significantly. |
| Remaining hook ref count | src/cli/dashboard/use-task-output-stream.ts:299 | 8 refs serve distinct polling purposes; further consolidation would require API redesign. |

## Commits Created
- `6ee8f6d` fix(dashboard): batch-a fixes — trySizeProbe extraction, closingRef guard, ASCII fast-path, header
