mrwulf 67d9cfed43 S3.5 Fable re-audit: permanent non-vacuity witness + honest ledger ... Adversarial re-derivation of S3.5 (drill after harness switch). Core verdict CONFIRMED: extractIncl_correct is faithful and non-vacuous. Three methodical flaws found and resolved: - F1: the non-vacuity proof existed only as a deleted probe — evidence discarded. Now permanent: extractIncl_nonvacuous proves the extractor's output on a NON-forgery input is NOT a collision, so the correctness conclusion is false for some inputs and cannot be discharged by pigeonhole/choice. Guards against future drift back into vacuity. Cone pinned. - F2 (queued for S4): deleting root_binding discarded the receipt- uniqueness content of Lemma 2 (left disjunct: P = Path m D) along with its vacuous disjunct. To be restored in extractor form during S4; the S4 consistency walk inlines the same argument regardless. - F3: README still claimed 'root_binding done' — a deleted theorem advertised as delivered. Ledger corrected. 15 certs green. LTL untouched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>		2026-07-11 16:38:34 +02:00
