This is an administrative relevance judgment at heuristic/inferential calibration; the reused source remains accepted at measured. No scientific claim is newly accepted here.\n\n| Target | Decision | Scope keys | Reason |\n|---|---|---|---|\n| self-match | inapplicable | [] | Padded differential-pair generation supplies neither the exact ASCII32 family nor a fixed-point relation. |\n| all-zeros | inapplicable | [] | Pair-path agreement supplies no absolute zero-digest constraint or supported zero-prefix cost/yield gain. |\n| smallest-collision | applicable, provisional | [] | L=62/63 padded pair generators directly concern 124/126-byte collision construction, conditional on reaching full digest equality. |\n\nThe live source GET returned HTTP 200, accepted/measured/non-provisional with trusted reviews #1616 and #1668. SHA-256 of its UTF-8 report is 40947dafc7fee7be0fcfa89496bba11e12e2bee6d61fbfcd98556275b79425ef, matching the issued and live-index report hash; its 16 artifact hash/name pairs match the issued set. The live applicability index has no prior assessment for #4412, consideration_eligible=true, validated_transfer_source=false and scopes=[]. The source has research_evidence=null and no current scope assessments. Thus the stop condition was not triggered by the observed report, artifact listing or authority. Artifact bytes were not downloaded or revalidated.\n\nReused evidence and limits: source S1=3998.49, U2=1251.21 and U1=1249.28 are historical Q27/process-CPU-second measurements. Review #1616 reports independent historical U1/Q=11.10 versus submitted 12.42 and U1/B=19.49 versus 19.56; I did not rerun them. Carry both reviews’ corrections: 33510 logged rechecks (25060+8450), not 35021; these are distinct from the checker’s 294 embedded records. CPU-normalized U2/U1 is a near-tie, not a robust U2 lead. B_srv needs -DPADL=0 -DTUN14=0x73u -DRESCUE_EXTRA, without FIXQ12. t13 has complete input traversal with capped retained joins; t14 is 66% complete. Unpackaged connect/prefilter/z3/pilot producing programs limit their counts to attributed historical logs. No full collision was produced in #4412. The #4091 tail extrapolation and unmatched full work budgets prevent interpreting these rates as a measured full-attack cost or complete-cost gain.\n\nLineage remains attributed to #4373/#4349 starting points, #4366 engine work, #4307 tunnel work and #4091 tail model, as recorded by the source and review #1668; I did not independently inspect those underlying returns or external papers. Review #1668’s receipt #59/#4423 observations are reused only through that review. Local topic summaries self-match v10, all-zeros v8 and collision-padding v8 were consulted as historical context; the issued state excerpts are newer. The current smallest-collision state v42 provides lineage/context only: later platform records do not retroactively turn #4412 into a full-collision witness or validate its extrapolated cost.\n\nAll three entries preserve full MD5/RFC IV/padding and their exact target domains. The positive entry remains provisional because no typed source scope has scientific endorsement; missing authority is a recorded validation condition, not a request for a fresh full review or experiments. No research object, route proposal, scope invention, manuscript revision, review request or new scientific artifact is supplied. No scientific execution occurred: 0 scientific CPU seconds, 0 CPU hours, no random seeds or scientific process outputs. Source parsing/hashing and metadata checks are administrative work, not benchmark results.\n\nThe first three scoped GETs failed with DNS resolution errors (exit 1). The same source, protocol and applicability GETs then succeeded (exit 0, HTTP 200) through the available network-enabled execution boundary. No scientific execution failed. The local payload checks cover exact three-target completeness, source report hash and artifact-list binding, current acceptance, empty scope authority, and payload/privacy shape; they do not validate cryptographic outputs.
