+## Measurement
+
+PR #37 (`feature/notify-f12 -> develop`, merge commit `a2cca66`)
+shipped F12 — stale + blind-spot push notifications per PRD-007 / RFC-006.
+
+Three layers of acceptance:
+
+- **Code review** — sub-agents (deps-f11 / lib-f11 in parallel) produced
+  patches matching RFC-006 algorithm spec: state machine for permission,
+  3 breach categories, throttle 60s per category, no-body-content
+  privacy guard, feature-detect for browsers without Notification API.
+- **Unit tests** — 9 new vitest in `entities/health/lib/notify.test.ts`:
+  snapshot extraction (id-set + counts); 3 breach types (blind_spot /
+  stale / orphan); identity / decrease cases (no false fires); permission
+  granted/denied/missing branches; throttle window with injectable now().
+  Total suite: 53 + 9 = **62/62**.
+- **CI smoke** — 3-OS × Node 22 green on PR #37.
+

+
+### Layer B — unit tests
+
+```
+Test Files  8 passed (8)
+Tests       62 passed (62)
+Duration    601ms
+```
+
+13 baseline + 7 sankey + 7 sunburst + 16 cluster + 6 keyboard-nav +
+2 regression + 6 markdown-renderer + 7 impact-graph + 9 notify = 62.
+
+### Layer C — CI matrix
+
+3-OS smoke matrix on PR #37 — all `success`. ubuntu/macos/windows ×
+Node 22.
+
+### Layer D — smoke
+
+`node scripts/smoke.mjs` PASS on develop locally:
+
+```
+[smoke] /api/health: ok (project=shim)
+[smoke] /api/list: ok (0 entries)
+[smoke] GET /: ok (HTML returned)
+[smoke] PASS
+```
+
+DOM verification deferred — Notification API requires real browser
+permission grant which can't be scripted via Playwright headless. Test
+plan in PR #37 includes manual verification once OS notification
+centre is open.

+
+## Congruence Level Justification
+
+**CL3 (same-context, penalty 0.0)**:
+
+- Vitest mocks the same Notification API the production browser bundle
+  uses. happy-dom environment matches Vite-bundled production runtime
+  contract.
+- CI smoke runs on Node 22 / ubuntu / macos / windows — exactly the
+  pinned engines from `package.json`.
+- `evidence_type: test` — every assertion is binary pass/fail with
+  deterministic input fixtures (mocked `Notification` constructor +
+  injectable `now()` clock).
+

+- **Copy as markdown** — ArtifactPanel gets a "📋 Copy as markdown" button next to the impact actions. Click writes a markdown summary of the selected artifact to the clipboard: id + title + status/kind/R_eff line + Outgoing/Incoming lists + body excerpt (first 500 chars + `...`). Closes the loop "PR review needs PRD context" — paste straight into a GitHub PR description / Slack thread / commit message. Visual feedback: ✓ Copied (green) on success, ✗ Copy failed (red) on error, both auto-revert after 2s.
+- **`widgets/artifact-panel/lib/markdown-export.ts`** — pure `buildMarkdownSummary(artifact, outgoing, incoming): string`. 6 vitest unit tests cover all fields, omitted Outgoing/Incoming when empty, R_eff formatting, body truncation past 500 chars, body section omitted when body is empty.
+
 ### Added (PRD-007 + RFC-006, F12)
 
 - **Stale + blind-spot push notifications** — HealthBar gets a 🔔 / 🔕 toggle. First click triggers `Notification.requestPermission()`; on grant, the user opts in. When the 10s `/api/health` poll detects a new blind_spot, a stale_count increase, or an orphan_count increase, a browser notification fires (silent, tagged per category, throttled to ≥ 60s per category). Click on a notification focuses the tab and selects the affected artifact via the `notifyBus.pendingFocus` singleton.
