Audit pass: full-corpus evidence, full-gate mutation, 3-way metamorphic, recomputable causal, bundle attestation
1 (artifact bundle): ci_reports writes evidence/MANIFEST.tsv (content hash+len of every evidence file); attestation verifies completeness+integrity; merge-gates requires the bundle. 2 (every leaf full evidence): run_all_to streams a full trace+delta record for EVERY leaf (base 'b' and perturbation 'p'), not a sample. 3 (attestation completeness): attestation enforces a leaf<->trace bijection (traces == leaves and covered set == leaf set), not just consistency. 4 (collapse derives from full traces): trace_feature_row single-sourced into collapse_analysis; attestation recomputes each collapse row from the retained full trace and requires bit-exact match. 5 (mutants through full gates): evaluate_mutants runs each mutant through engine_acceptance over 128 generated cases (trace/equivalence/domain/ metamorphic/causal), replacing the 64-input local predicates. 6 (trace+delta+future): metamorphic enforces consumed->trace per-case plus consumed-aggregate delta (>=0.65) and future (>=0.80) rates. 7 (recomputable causal): per-edge intervention records written to evidence/causal_evidence.tsv; attestation RE-EXECUTES each from its seed and recomputes base_dv/alt_dv. 8 (no string/comment proof): removed web_assets JS-substring test and the tautological string assert in ci_reports. Verified at fast scale end-to-end: 6600/6600 traces reconstructed, leaf bijection, 1600/1600 causal records recomputed, 600/600 collapse rows derived, bundle intact.
