Architecture Highlights

Telemetry Layer

AgentSpanManager
  ├── startSpawnSpan()        // Agent creation
  ├── startExecutionSpan()    // Task execution
  ├── completeExecutionSpan() // Task completion
  └── recordErrorSpan()       // Error tracking

• W3C context propagation
• Automatic parent-child span relationships
• Semantic attributes (agent.id, task.type, etc.)
• Auto-cleanup after 5 minutes (prevents memory leaks)

Cost Tracking

CostTracker
  ├── trackTokenUsage()       // Record usage
  ├── calculateCost()         // Provider-specific pricing
  ├── getAgentCosts()         // Per-agent breakdown
  └── getTotalCost()          // Fleet total

• Multi-provider support (Anthropic, OpenRouter, ONNX)
• Cache-aware pricing (25% write premium, 90% read discount)
• January 2025 pricing tables
• Prometheus-compatible metrics

Constitution Evaluation

EvaluatorFactory
  ├── ASTEvaluator           // Babel AST analysis
  ├── MetricEvaluator        // Quantitative metrics
  ├── PatternEvaluator       // Regex patterns
  └── SemanticEvaluator      // LLM semantic analysis

• Pluggable evaluator architecture
• Operator support: >, <, =, !=, >=, <=, contains
• Field extraction from context
• Detailed findings with evidence

Voting System

VotingOrchestrator
  ├── assemblePanel()         // PanelAssembler
  ├── distributeTask()        // Parallel distribution
  ├── collectVotes()          // With timeout/retry
  ├── aggregateVotes()        // ConsensusFactory
  └── publishResult()         // With metadata

• Panel assembly with expertise scoring
• Parallel vote collection (race with timeout)
• 3 consensus algorithms (majority, weighted, Bayesian)
• Comprehensive metrics (participation, confidence, agreement)

---

Integration Points

Phase 1 Dependencies (✅ Available)

• Telemetry Bootstrap (src/telemetry/bootstrap.ts)
• Metrics Schema (src/telemetry/types.ts)
• Constitution Schema (src/constitution/schema.ts)
• Constitution Loader (src/constitution/loader.ts)

Phase 3 Requirements (✅ Ready to Provide)

• Trace data for visualization (AgentSpanManager.getSpans())
• Metrics for dashboards (CostTracker, PerformanceTracker)
• Evaluation results for display (VotingOrchestrator.aggregateVotes())

Phase 4 Integration (Planned)

• CLI commands (aqe telemetry, aqe constitution)
• MCP tools (aqe_telemetry_status, aqe_constitution_evaluate)
• CI/CD workflows (GitHub Actions quality gate)

---

Performance Characteristics

Algorithmic Complexity

• AST Traversal: O(n) nodes
• Consensus Algorithms: O(n) votes
• Panel Assembly: O(n log n) sorting
• Vote Collection: O(n) parallel (bounded by timeout)

Resource Usage

• Telemetry: Bounded by active span count (<100 concurrent expected)
• Cost Tracker: In-memory maps (recommend LRU eviction after 10K entries)
• Voting: Temporary storage during collection, cleaned after aggregation

Performance Targets

• Clause evaluation: <5s per file (✅ achievable with AST/Metric/Pattern)
• Panel assembly: <1s for 100 agent pool
• Vote collection: <60s for 10 agents (with 30s timeout)
• Consensus calculation: <100ms for 10 votes

---

Known Limitations

1. Semantic Evaluator: LLM-dependent, may be slow/expensive

   • Mitigation: Heuristic fallback mode (regex-based)
   • Future: Cache LLM results by (code_hash, field) key

2. Cost Tracker: Unlimited growth

   • Mitigation: Recommended LRU eviction (10K entries)
   • Future: Configurable retention policy

3. No CLI Yet: Functionality ready, CLI wrappers in Phase 4

   • Mitigation: Direct API usage possible
   • Future: aqe telemetry and aqe constitution commands
