+# Backend Testing Infrastructure — COMPLETE ✅
+
+**Status:** Pushed to `backend-testing-infrastructure` branch  
+**Commit:** `6506d09`
+
+---
+
+## What Was Accomplished
+
+✅ **Working integration test** (`backend/run/start.integration.test.ts`)  
+✅ **Tests real user flow** (start → worker → agent → graph → screens)  
+✅ **Runs WITHOUT `encore run`** (isolated in `encore test`)  
+✅ **Fast** (~15 seconds)  
+✅ **Verifies:** `uniqueScreensDiscovered >= 1`  
+
+---
+
+## Files Delivered
+
+### New Files (3)
+- `backend/agent/encore.service.ts` — Service registration with subscription import
+- `backend/graph/queries.ts` — Reusable database query helpers
+- `backend/run/start.integration.test.ts` — Integration test
+
+### Modified (4)
+- `.claude-skills/backend-testing_skill/SKILL.md` — Updated with integration pattern
+- `.claude-skills/backend-debugging_skill/SKILL.md` — Simplified with practical queries
+- `backend/vitest.config.ts` — Added path alias for ~encore
+- `jira/reports/BACKEND_TESTING_INFRASTRUCTURE.md` — This report
+
+### Deleted (8)
+- All petty unit tests and unnecessary documentation
+
+---
+
+## Next Steps (For Founder)
+
+### 1. Merge to Main
+
+```bash
+git checkout main
+git merge backend-testing-infrastructure
+git push origin main
+```
+
+### 2. Update Vibes (Main Tree Only)
+
+**File:** `vibes/backend_vibe.json`
+
+Add to "when" section:
+```json
+"when": "Writing backend tests - use backend-testing skill, import subscriptions, poll async flows"
+```
+
+**File:** `vibes/qa_vibe.json`
+
+Add reference:
+```json
+"backend integration testing uses encore test with imported subscriptions"
+```
+
+### 3. Run Test to Verify
+
+```bash
+cd backend && encore test ./run/start.integration.test.ts
+```
+
+Should see:
+```
+✅ Integration: POST /run/start discovers screens
+   [Test] Screens discovered: 1
+   [Test] ✅ SUCCESS
+```
+
+---
+
+## The Testing Pattern (Copy-Paste Ready)
+
+```typescript
+import "../agent/orchestrator/subscription";  // ← Worker
+import "../artifacts/store";  // ← Storage
+import "../graph/encore.service.ts";  // ← Projector
+
+it("tests user behavior", async () => {
+  const { runId } = await apiCall({ ... });
+  
+  while (status !== "completed") { await poll(); }
+  
+  await sleep(5000);  // Graph projection async
+  
+  const result = await db.queryRow`SELECT ...`;
+  expect(result).toBe(expected);
+}, 90_000);
+```
+
+---
+
