Reserved-buffer headroom guard on the Docker-data volume (system/dockervol.go, max(5GB,10%)); deploy-time hard gate refuses (HTTP 507) when below the buffer (api/router.go); deploy page warns + disables the button (deploy.html); runtime disk monitor confirmed to watch the Docker volume above the buffer. Log rotation baked into the golden (agent side). Phase 1 = felhom-agent v0.29.0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
