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.
