 | R1 | Add candidate family clustering evidence schema (CFC-) (complete). — src/openamp_foundry/evidence/candidate_family_clustering.py: CFC- 15-field schema; VALID_NOVELTY_EVIDENCE_TYPES (6), VALID_CLUSTERING_METHODS (5), VALID_NOVELTY_VERDICTS (4); novel_family requires hard evidence (blast/hmm/structural/charge); variant_of_known requires known_family_hits; n_candidates≥2 enforced; dry_lab_only=True enforced; 66 tests in tests/evidence/test_candidate_family_clustering.py. | Machine-verifiable grouping of related candidates into a "novel family" claim; sequence similarity threshold, family size, novelty evidence type controlled vocabulary. | B/C |
 | R2 | Add family novelty report schema (FNR-) (complete). — src/openamp_foundry/evidence/family_novelty_report.py: FNR- 13-field schema; VALID_BASELINE_COMPARISON_OUTCOMES (4), VALID_NOVELTY_STRENGTH_GRADES (4), VALID_CHEAP_BASELINES_CHECKED (5); strong grade requires outside_known_space; not_supported incompatible with outside_known_space; cheap_enemy_score/family_score in [0,1]; dry_lab_only=True enforced; 64 tests in tests/evidence/test_family_novelty_report.py. | Bundles CFC- clustering with cheap-baseline comparison; prevents "novel family" overclaim when candidates are merely sequence variants of known AMPs. | B/C |
 | R3 | Add full audit trail report schema (ATR-) linking BSP→WHR→PCU→HCR→PQG for a complete dry-lab→wet-lab loop trace (complete). — src/openamp_foundry/evidence/audit_trail_report.py: ATR- 15-field schema; REQUIRED_ATR_STAGES (5: BSP/WHR/PCU/HCR/PQG), VALID_TRAIL_COMPLETENESS_STATUSES (4), VALID_CHAIN_INTEGRITY_GRADES (5); complete status enforces all 5 stages; grade D incompatible with complete; build() auto-computes n_stages_complete; dry_lab_only=True enforced; 70 tests in tests/evidence/test_audit_trail_report.py. | End-to-end chain of custody from nomination to confirmed hit; required for scientific reproducibility. | B/C |
