Addresses the attached findings as blocking compliance failures. Each fix removes a substitution pattern and adds a negative-control test. Finding 9 (hash changes != enforced metamorphic expectations): ci_reports now enforces a sound metamorphic relation per perturbation — a perturbation the program CONSUMES must alter the trace — grounded in reachability, with a non-vacuity check. Test: consumed_perturbation_must_alter_trace. Finding 10 (trace counts != causal explanation): New causal_explanation gate ablates each recorded causal edge's source lane and requires the destination delta to change. Measured: true-source 0.77 vs scrambled-source 0.03. Threshold 0.50. New required report causal_explanation_report. Test: causal_edges_are_intervention_confirmed_not_counted. Finding 6 (static seed corpus != failure retention): replay_corpus::retention adds a committed, append-only counterexample corpus (retained_failures.tsv) re-verified every run against the independent runtime. Negative control: reintroduced_bug_is_caught_by_retention. Finding 5 (mini mutation evaluator != real acceptance gate): Mutants are now killed by ci_reports' OWN acceptance-gate predicates with single-sourced thresholds (TRACE_EDGES_MIN, etc.); evaluate_mutants replaces semantic_mutation::run_suite on the acceptance path. Test: mutants_killed_by_real_acceptance_gates. Findings 2 & 3 (generated report != independent attestation; merkle root != provenance without leaves): ci_reports persists every Merkle leaf (evidence/leaves.tsv) + claims. New `attestation` crate + `attest` binary recompute the root from the leaves in a SEPARATE process that never reads compliance_report.json; wired as a distinct merge-gates step. Negative control: tampered_leaf_breaks_attestation. Finding 8 (structural indicators != measured behavior): Domain gate already requires measured influence/mutation/removal; added an explicit reject for "appears structurally but no measured influence". Finding 1 (workflow != merge enforcement): BLOCKED on server-side branch protection. Added .github/rulesets/main-required-checks.json + apply command; enforcement still requires a repo admin to activate the ruleset. Finding 7 (protocol socket E2E != rendered browser E2E): BLOCKED on a CI browser runner; rendered-browser E2E remains advisory-only. Finding 4 (trace summary != full trace evidence): PARTIAL. Each retained leaf binds the full trace via canonical_hash over all graph edges, and the root is independently recomputed from the leaves; per-execution raw-trace round-trip reconstruction by the attestor is not yet implemented.
