Protocol analysis: effectiveness review and improvement proposals

[Copilot]

Comprehensive analysis of the quorum protocol architecture — no code changes. Covers all core subsystems (consensus, parliament, fitness, enforcement gates, stagnation detection, adapter pattern) and identifies concrete improvement areas.

Key Findings

Protocol Strengths

• Conditional Trigger (12-factor) — cost-accuracy tradeoff automation prevents wasteful 3-model consensus on micro-changes
• Fitness Score Engine — "measurable things are not asked to the LLM" principle delivers deterministic, zero-cost quality gating
• Stagnation Detection (7 patterns) — most practical feature; prevents infinite audit loops via SHA-256 spinning detection, oscillation detection, and auto-escalation
• 3-Layer Adapter Pattern — new adapter = ~650 LOC I/O wrapper vs ~2000 LOC full implementation

Improvement Areas

• Adapter hook coverage imbalance: Claude Code (22 hooks) vs Gemini (11) vs Codex (5). Define Minimum Viable Hooks set and document feature matrix per adapter
• Normal Form convergence is declared but unverified: impl(A, law) = impl(B, law) principle lacks cross-provider convergence comparison mechanism. Needs structural fingerprint diffing
• Confluence verification partially manual: checkIntentResult and checkLawLaw depend on externally-provided inputs (CPS gaps, lawContradictions). Should auto-extract from EventStore and Amendment history
• Fitness weights hardcoded: FitnessConfig.weights type exists but no config.json integration. Security-focused projects need different weight profiles
• Parliament convergence overly permissive: entropy-based convergence detects classification stability but not content sufficiency — empty decisions/risks registers can still "converge"
• Fail-open security tradeoff: all gates fail-open by design. Critical gates (Verdict, Amendment) should support optional fail-close via gates.failPolicy config
• SQLite single-writer contention: WAL mode helps reads but parallel agent writes through ParallelPlanner can bottleneck. Consider per-agent write buffer with periodic merge
