+# Sprint 07 — Operations Hardening
+
+**Status:** Completed ✅
+**Goal:** Fix critical gaps in system backups, log rotation, container resource management, and health monitoring.
+
+---
+
+## S07.1 — Implement audit log rotation [Completed ✅]
+
+- **Files:** `dashboard/backend/main.py`
+- **Action:** Replaced `logging.FileHandler` with `logging.handlers.RotatingFileHandler` (10MB limit, 5 backup files).
+- **Verification:** Standard requests function properly; Python syntax checked and tests passed.
+
+## S07.2 — Fix database backups (Add OPC & remove dead paths) [Completed ✅]
+
+- **Files:** `backup.sh`
+- **Action:**
+  1. Added `OPC DB` dump using pg_dump.
+  2. Added `/volume1/docker/nas-dashboard/rbac.json` and `audit.log` config paths to the configs backup block.
+  3. Removed the deprecated `/volume1/docker/openclaw/data` path.
+- **Verification:** Shell script verified for syntax.
+
+## S07.3 — Enhance health check endpoint [Completed ✅]
+
+- **Files:** `dashboard/backend/main.py`
+- **Action:** Enhanced `/api/health` to dynamically query database pool availability, docker ping status, and disk space usage. Returns HTTP 503 if any critical service is down.
+- **Verification:** Integration test suite verified that endpoint changes compile and execute cleanly.
+
+## S07.4 — Set Docker container resource limits [Completed ✅]
+
+- **Files:** `dashboard/docker-compose.yml`, `claude-dev/docker-compose.yml`
+- **Action:** Added container memory limits and CPU limits (`mem_limit` and `cpus` service-level directives).
+- **Verification:** Compose YAML structures verified via linter and schema checker.
