# Phase G Implementation Plan (Maps to External Review Phase 3) One-line YES/NO: YES — Production scaling plan with caching, balancing, auto-scaling, monitoring, and enterprise features. EXAI-MCP summary: provider=GLM primary; cost=$0 for planning; total call time≈instant ## Objectives and Outcomes - High-scale performance: advanced context caching, load balancing, auto-scaling, production monitoring - Enterprise features: RBAC, audit/compliance, advanced security, DR ## Scope (Phase 3.1–3.2) - 3.1 Performance & Scalability: caching, balancing, auto-scaling, monitoring - 3.2 Enterprise Features: RBAC, audit/compliance, advanced security, backups/DR ## Deliverables - caching/intelligent_cache.py (semantic-aware, TTL, limits) - balancing/intelligent_lb.py (health, dynamic routing, failover) - scaling/auto_scaling.py (predictor, optimizer, policies) - monitoring/prod_monitoring.md + alerts config - security/rbac.py, audit/system.py, security/advanced.py, dr/disaster_recovery.md - Tests: performance/load, health checks, authz tests, DR drills ## Sequencing (6–8 weeks) 1) Performance Foundations (Weeks 1–2) - IntelligentContextCache MVP: direct hits + semantic index stubs; eviction policy LRU+similarity - Performance harnesses and metrics collection 2) Load Balancing & Monitoring (Weeks 2–3) - IntelligentLoadBalancer MVP with health probes; dynamic routing - Production monitoring skeleton + dashboards wiring 3) Auto-scaling (Weeks 3–4) - AutoScalingManager MVP: demand predictor stubs, policies, cooldowns - Integrate with monitoring signals 4) Enterprise Features (Weeks 4–6) - RBAC roles/permissions, session tokens; audit logging categories - Advanced security (encryption hooks, threat detection stub) - DR doc + automated backup procedures 5) Hardening & Drills (Weeks 6–8) - Load tests (50 concurrent users, <2s target) - Security battery; DR failover table-top + limited drill ## Success Criteria (per external prompt) - Cache hit rate >80% with >85% semantic accuracy - Load distribution efficiency >90% - Auto-scaling responds within 2 minutes - Monitoring coverage >95%; alert accuracy >90% - RBAC, audit/compliance, advanced security functional; DR procedures validated ## Dependencies - Phases E and F completed; keys/configs; logging pipeline ## Risks/Mitigations - Production drift: codify infra-as-config; version dashboards - False positives in alerts: tune thresholds with historical data - DR complexity: start minimal; verify restore paths first ## Verification Plan - Load/perf tests, health checks, chaos-style probes for failover - Security/penetration tests; RBAC/authorization tests; DR runbook validation ## Rollout - Staged environment validation → production enablement → post-implementation review
