## Phase 111 Completion Report
**Implemented/Verified:**
- `#kb-banner` contains a `<button type="button" class="banner-retry" id="banner-retry">` (hidden by default, Retry label + SVG)
- `showErrorBanner(detail, opts)` reveals the button only when `opts.retryable` is true AND `lastBrainWrap` exists
- Turn-error path passes `{ retryable: true }`; all non-turn callers (share, save-doc, stale) remain text-only
- `clearErrorBanner()` re-hides the button
- `ERROR_HINT` changed from "Try again — …" to "If this persists, check the LLM is reachable."
- `.banner-retry` CSS styled as a pill (matching `.stale-regenerate` family)
- 12 source-assertion unit tests in `tests/unit/test_frontend_banner_retry.py`
**Test / Lint / Coverage:**
- `uv run pytest tests/unit/test_frontend_banner_retry.py -v --no-cov` → 12 passed
- `uv run pytest --cov=app --cov-report=term-missing` → 2362 passed, 99% coverage
- `uv run ruff check .` → All checks passed
- `uv run pyright` → 0 errors
- `tests/e2e/test_llm_retry.py` → 4 passed (in isolation)
- `tests/e2e/test_smoke.py` → 3 passed (in isolation)
**Completion Criteria:**
- ✅ Retry button visible after failed chat turn, re-runs last question
- ✅ Non-turn callers show text-only banner (no button)
- ✅ pytest green, coverage >90%, ruff + pyright clean
- ✅ Phase dir to be moved by pipeline gate
**Next pending phase:** `112_honesty_gate_weak_hits`
