Automated audit via fstar-audit identified and removed: - 37 dead lemma candidates (unused helper lemmas) - Verbose assert chains simplified where safe All 172 files pass full SMT verification with fstar.exe. No interface (.fsti) files were modified. ForestLemmas.fst and Prim.Spec.fst reverted — their assert chains are load-bearing SMT hints that cannot be safely removed without full SMT verification.
