Benchmark v3 Release Readiness

The benchmark is treated as a benchmark-v3 evidence product: stable metric groups keep contract compatibility, while certification, claims, budget and export layers provide release guardrails.

Evidence policy

• stable metric groups: loc_sloc, top_modules, coupling_cohesion, solid_clean_oop, coverage_confidence, industrial_maintainability, quality_gates, evidence_trust, public_evidence_integrity, source_verification, trust_center, runtime_certification, claims_ledger, quality_budgets, evidence_exports.
• experimental metric groups: feature_parity, governance_compliance, security_supply_chain, operational_reliability, operability_tco, architecture_taxonomy, complexity_boundary, semantic_maintainability, scoring_calibration, scale_readiness, refactor_roi, independent_validation, external_analyzer_results, candidate_quality_delta, trend_summary.
• Policy: Benchmark v3 keeps stable code-quality, release-certification and evidence-integrity metrics contract-compatible. Experimental posture, projection and roadmap metrics can evolve with explicit version notes.
