+# Phase 9 Plan 3: E2E Test Suite Summary
+
+**Playwright E2E tests covering create/edit/search/organize/delete workflows with database seeding fixtures and desktop+mobile viewport testing**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-02-03T22:32:42Z
+- **Completed:** 2026-02-03T22:38:28Z
+- **Tasks:** 3
+- **Files modified:** 6
+
+## Accomplishments
+
+- Configured Playwright for E2E with multi-viewport testing (desktop + mobile)
+- Created database seeding fixture with 5 entries, 3 tags, and entry-tag relationships
+- Wrote 17 E2E tests covering all 5 core user journeys (34 total with 2 viewports)
+- Separated Docker deployment tests into own config to preserve existing workflow
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Update Playwright configuration** - `3664afb` (feat)
+2. **Task 2: Create database seeding fixture** - `283a921` (feat)
+3. **Task 3: Write E2E tests for user journeys** - `ced5ef2` (feat)
+
+## Files Created/Modified
+
+- `playwright.config.ts` - E2E config with multi-viewport, screenshots on failure, webServer
+- `playwright.docker.config.ts` - Separate config for Docker deployment tests
+- `tests/e2e/fixtures/db.ts` - Database seeding fixture with predictable test data
+- `tests/e2e/index.ts` - Re-exports extended test with seededDb fixture
+- `tests/e2e/user-journeys.spec.ts` - 17 E2E tests for core user journeys (420 lines)
+- `package.json` - Updated test:e2e:docker to use separate config
+
+## Decisions Made
+
+1. **Single worker execution** - Shared SQLite database requires sequential test execution to avoid race conditions
+2. **Manual cleanup over drizzle-seed reset** - reset() has type incompatibility issues with schema; direct SQL DELETE is more reliable
+3. **Separate docker config** - Preserves existing docker-deployment.spec.ts workflow without interference from E2E webServer config
+4. **Predictable test IDs** - Test data uses fixed IDs (test-entry-001, etc.) for reliable assertions
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+1. **drizzle-seed reset() type errors** - The reset() function has type compatibility issues with BetterSQLite3Database when schema is provided. Resolved by using direct SQL DELETE statements instead, which provides better control over cleanup order anyway.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- E2E test suite ready for CI pipeline integration
+- All 5 user journeys covered: create, edit, search, organize, delete
+- Tests verified working locally with webServer auto-start
+- Ready for 09-04 (GitHub Actions / CI workflow)
