Reconcile Mach-O UUID observations without hiding malformed or conflicting sources. Require source-map identity digests to be supported by consistent observations. Keep truncated Android manifests as partial raw evidence, validate WABT section framing, and reject missing JEB inventories or error-marked success replies. Consolidate native UUID parsing and simplify capacity and malformed-input fixtures. Focused source and public workflow checks pass, including native arm64e inspection and real WABT framing probes; a successful real JEB GUI project opening remains unverified.
