v1.5.0

Added

• Autonomous Self-Healing Container Policies & Remediation Engine (internal/healing/engine.go):
  • Autonomous failure detection and recovery engine executing automated restarts on Out-Of-Memory (OOM) killed containers (Exited (137)), flapping restart loops (restarting), and failed Docker health checks (unhealthy).
  • Thread-safe configuration repository (internal/healing/policy.go) with input sanitization, boundaries validation, and container exclusion filters (dock-radar.healing=false label and excluded_containers rules).
  • Exponential backoff with randomized cryptographic jitter (internal/healing/jitter.go) desynchronizing restart bursts to prevent daemon socket saturation and cascading failure thrashing.
  • Rollback protection & quarantine circuit breaker: tracks per-container remediation attempts, halting automated restarts and placing recurrently failing containers in quarantine once max_attempts is reached.
  • Bounded circular remediation audit trail buffer (internal/healing/history.go) capturing timestamped failure triggers, attempt counters, jitter delays, and execution outcomes with zero-allocation retrieval.
• Self-Healing REST APIs (internal/api/healing.go):
  • GET /api/healing/config: Returns active remediation rules and thresholds (requires RoleViewer).
  • POST /api/healing/config: Atomically updates self-healing policy configuration (requires RoleAdmin with rate limiting).
  • GET /api/healing/status: Real-time remediation KPIs, active backoffs, and list of quarantined containers.
  • GET /api/healing/history: Filterable remediation audit trail events (?limit=, ?container_id=, ?trigger=).
  • POST /api/healing/reset: Clears circuit breaker states for a specific container or all quarantined services.
• Prometheus Metrics Exporter Enhancement (internal/metrics/prometheus.go):
  • Exposes dock_radar_healing_enabled, dock_radar_healing_remediations_total, dock_radar_healing_quarantined_containers, and dock_radar_healing_active_backoffs gauges for observability dashboards.
• Embedded Dark-Mode Dashboard Additions (web/dist/index.html):
  • Header status pill indicator (🛡️ Healing: Active / Quarantined) with quick-action modal trigger.
  • Dedicated Self-Healing & Remediation section featuring real-time KPI overview cards, live remediation audit feed, and one-click circuit breaker reset triggers.
  • Interactive Self-Healing Policy configuration modal with input toggles and parameter tuning.
• Modularization Refactoring:
  • Extracted log streaming handlers to dedicated internal/api/logs.go module, streamlining internal/api/handlers.go to strictly adhere to the 300-500 line soft ceiling across all files.
• Comprehensive Unit Test Suites:
  • Added full test coverage across internal/healing/policy_test.go, internal/healing/jitter_test.go, internal/healing/history_test.go, internal/healing/engine_test.go, internal/api/healing_test.go, and internal/metrics/prometheus_test.go.
