+
+**Health check endpoint with database verification, environment documentation, and Docker volume backup script**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-02-01T12:22:33Z
+- **Completed:** 2026-02-01T12:24:40Z
+- **Tasks:** 3
+- **Files modified:** 4
+
+## Accomplishments
+
+- /health endpoint returns 200 when database is accessible, 503 on failure
+- .env.example documents all configuration options (PORT, ORIGIN, TASKPLANER_DATA_DIR, BODY_SIZE_LIMIT, proxy headers)
+- backup.sh creates timestamped tar.gz archives of the Docker volume
+- README.md updated with comprehensive Docker deployment section
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create health check endpoint** - `de09b14` (feat)
+2. **Task 2: Create environment documentation and backup script** - `c92cb3e` (feat)
+3. **Task 3: Add Docker deployment section to README** - `f3a5449` (docs)
+
+## Files Created/Modified
+
+- `src/routes/health/+server.ts` - Health check endpoint with database connectivity verification
+- `.env.example` - Environment variable documentation with all configuration options
+- `backup.sh` - Docker volume backup script creating timestamped archives
+- `README.md` - Docker deployment section with quick start, config, backup instructions
+
+## Decisions Made
+
+- Health check performs actual database query (select from entries limit 1) to verify full stack connectivity, not just server responsiveness
+- Backup script uses temporary Alpine container to access volume contents, avoiding need for container to be running
+- README includes reverse proxy configuration section for nginx/traefik deployments
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Docker deployment is complete and ready for production use
+- All Phase 6 (Deployment) objectives met:
+  - Dockerfile with multi-stage build and non-root user
+  - docker-compose.yml with named volume
+  - /health endpoint for container health monitoring
+  - Environment documentation
+  - Backup script for data preservation
+  - README with deployment instructions
