Phase 6-7: Deployment, Observability & Project Finalization

Overview

Final phases to transform System//Zero from functional prototype to production-ready, deployable system with enterprise observability, security hardening, and comprehensive documentation.

---

Phase 6: Observability + Deployment Hardening

Goal: Secure, observable deployment with operator metrics and configuration management.

Duration: ~8-10 hours
Prerequisites: ✅ Phase 5 complete (REST API + CLI server operational)

6.1 Authentication & Authorization (2 hours)

Objective: Secure the API with token-based authentication

Tasks:

1. API Key Authentication

   • Add X-API-Key header validation middleware
   • Create config/api_keys.yaml for key storage (hashed)
   • Add /auth/token endpoint for key generation
   • Implement key rotation utilities

2. Role-Based Access Control

   • Define roles: admin, operator, readonly
   • Add role checks to sensitive endpoints (POST /captures, POST /templates)
   • Create permission matrix documentation

3. Security Configuration

   • Add CORS configuration (configurable allowed origins)
   • Implement rate limiting (per-IP, per-key)
   • Add request size limits
   • Enable HTTPS support (TLS config)

Files:

• interface/api/auth.py - Authentication middleware
• interface/api/security.py - Rate limiting, CORS
• config/api_keys.yaml - Key storage
• tests/test_api_auth.py - Auth tests

Success Criteria:

• Unauthorized requests return 401
• Role restrictions enforced on POST endpoints
• Rate limits prevent abuse (100 req/min default)
• Tests: +10 auth tests passing

---

6.2 Observability & Metrics (2.5 hours)

Objective: Add structured logging, metrics, and health monitoring

Tasks:

1. Structured Request Logging

   • Add middleware to log all requests (method, path, status, latency)
   • Log format: JSON with timestamp, request_id, user_agent, IP
   • Separate log file: logs/api_requests.log
   • Implement log rotation (daily, keep 30 days)

2. Metrics Collection

   • Track request counters by endpoint
   • Track latency histograms (p50, p95, p99)
   • Track error rates by status code
   • Add /metrics endpoint (Prometheus format optional)

3. Health & Readiness Probes

   • /health - Liveness probe (always returns 200 if server up)
   • /ready - Readiness probe (checks log file, templates dir)
   • Graceful shutdown handler (SIGTERM handling)
   • Connection drain period (30s default)

4. Dashboard Enhancements

   • Add API health to GET /dashboard (uptime, req/s, error rate)
   • Add ingestion counters (captures today, templates created)
   • Add performance metrics (avg response time)

Files:

• interface/api/middleware.py - Request logging, metrics
• interface/api/health.py - Health check endpoints
• core/utils/metrics.py - Metrics tracker
• tests/test_api_observability.py - Observability tests

Success Criteria:

• All requests logged to logs/api_requests.log
• /health and /ready return proper status
• /dashboard includes API metrics
• Tests: +8 observability tests passing

Technical Debt Backlog

Items from prior phases that are not blockers but could improve quality:

From Testing Strategy Debrief

1. Enhancement Tests (21 failing tests from Phase 2.5) - These test advanced features but don't block core functionality:

   • Matcher.calculate_score edge cases
   • DiffEngine detailed structure comparisons
   • NodeClassifier additional role types
   • NoiseFilters advanced filtering rules

2. Test Maturity - Expand test fixtures:

   • Add Gmail, Settings, Login fixtures to template gallery
   • Create more drift scenarios (manipulative patterns, sequence violations)
   • Add performance test fixtures (large trees, deep nesting)

From Phase 4 Completion

1. Template Versioning - Track template history:

   • Add version field to template YAML
   • Implement rollback/history tracking
   • Create template diff tool

2. Template Management - Advanced features:

   • Import/merge templates from external libraries
   • Bulk template generation from captures
   • Template validation against multiple captures

3. Capture Enhancements:

   • Add filters (by app, date range)
   • Support incremental updates
   • Capture comparison tool

Code Quality

1. Type Coverage - Add type hints to remaining modules (currently ~90%)
2. Docstring Coverage - Ensure all public functions have docstrings
3. Duplicate Code - Refactor drift_event.py (3 versions exist: old, new, main)
