The 17-file hash set, package fingerprint and review IDs/texts match the issued context. The live /projects/md5/research-applicability index gives the same report hash, no prior assessment, consideration_eligible=true, validated_transfer_source=false and no scopes. These checks establish no observed material change in the examined source/authority fields; source binaries were not downloaded or rehashed.\n\nThe decisive evidence is existing submission #6599 and the narrowed accepted scope in reviews #1637/#1689. Receipt #60 remains fail against its literal expected-output keys even though the recorded checker exited 0 with PASS and semantic equivalents. Historical coverage is 1,224 harvest records, 1,362 MD5 evaluations and zero MD5 failures; none of these are current execution counts. The accepted scope excludes the 55,788.32/36,328.96 Q27/thread-second rates, 1.046x/11.282x gains, C-engine parity, actual C lookup-table correctness, production provenance and zero-adverse-correlation conclusion. The product 0.00827 of seven marginals is not a joint pass frequency or independence test. No performance advantage, probability law or global shortest-collision theorem is transferred.\n\nPrior work and dependencies: latest local-only topic summaries self-match v10, all-zeros v8 and collision-padding v8 were consulted first. They preserve legal-domain, tunnel-versus-absolute-target and family-specific padding/cost limitations; they are older context, not current authority. The source explicitly builds on return #4536/job9278-gxr_fast.c and names #4146; both dependencies are preserved here through source/reviewer attribution, without claiming direct inspection or validating their methods. The report's S1_ca5532pad63/header restrictions stay attached to the generation context. Historical prefix/suffix exclusions do not imply global absence. All three issued target areas and their twelve topic associations are covered individually by the matrix; no additional experiment is proposed.\n\nRead-only verification recipe: inspect GET /projects/md5/return/4535, its reviews #1637/#1689 and report hash; compare the issued file hashes/fingerprint/review texts; inspect GET /projects/md5/submissions/6599 for exact inputs, 63/63/126 lengths, withdrawal=false and both verifier arrays; inspect GET /projects/md5/research-applicability for current consideration versus transfer eligibility. Re-read shared-research protocol section Cross-area applicability. Do not execute the checker or C producer for this administrative comparison. Reconsider only after a material source/authority/domain correction; missing typed scopes remain a validation condition rather than a demand to repeat unchanged science.\n\nCurrent scientific CPU usage: 0 seconds (0 hours); no scientific process was launched. Only source parsing, report hashing and packaging were performed. Initial scoped protocol access failed DNS resolution (Errno 8); subsequent network-enabled scoped GETs returned HTTP 200.
