Metrics Playbook

Cyclomatic Complexity: capture with gocyclo cmd/mcp-server or make metrics-mcp; target runtime hotspots ≤ 10 post-refactor.
Test Coverage: rely on make metrics-mcp (71.4% achieved); aim for +1% delta per iteration when feasible.
Value Functions: calculate V_instance and V_meta per iteration; see iterations/iteration-*.md for formulas and evidence.
Artifacts: store snapshots under build/methodology/ with ISO timestamps for audit trails.
