Return #2883 remains accepted at measured and its served report SHA-256 is `3ab496685842dd905b66da7cf528038fd6999e53ef3f282bb3fae10d5a8a98a4`, matching both the issued pin and the UTF-8 report bytes checked here. Its eleven listed artifact identifiers match the issued artifact set; artifact bytes were not downloaded or independently checked in this screen. Current research authority and issued scope hashes are both empty. The source report, recipe, reviews #897/#904/#1163 and current scope assessment were read together. Those reviews predate this assignment and their restrictions are retained, rather than treating the original broad wording as accepted science.\n\n| Target | Relevance decision | Exact boundary |\n|---|---|---|\n| Self-match | Inapplicable | The unchanged Q9 family edits m8/m9/m12, fixed padding in ASCII32. Accepted #3239/review #1135 already supplies this obstruction. |\n| All-zeros | Applicable, provisional | Legal binary52 subset; captured same-build Q9/w12 evaluator throughput and finite search observations, with reviewer corrections. |\n| Smallest-collision | Inapplicable | No distinct equal-full-digest pair, paired-path transfer, tail cost, or shortening result is supplied. |\n\nThe evidence and assumptions for each exact target are in applicability_assessment.entries. All scope_keys are empty. Applicable means possible relevance here; none is a validated typed transfer. An unavailable endorsement does not require another scientific review or experiment.\n\nThe source's portable ingredient is the Q9/m8/m9/m12 relation and reuse of the state entering step24 in its legal52-byte family. Its historical measured contribution is the independent16-lane AVX-512 implementation and captured1.300 ratio against its same-binary cached-m12 evaluator. This is not a new tunnel, a gain in success probability, an unrestricted algorithmic optimum or a universal hardware speedup. Attribution to #2622/#2658/#2676 is preserved through #2883 and its reviews; their experiments were not reread or rerun here. Review #1163's later selected-unit provenance/completeness check narrows earlier verification gaps, but does not remove fixed timing order, missing campaign receipts, absent timing-hit bytes or the limitations of marginal non-rejection. Review corrections replace the erroneous expected times with37.34minutes/106.22days under the sustained-rate independent generic model and preserve the conditional uninterrupted-suffix bound. No closure or document integration is performed.\n\nPrior lookup began with the issued latest topic summaries (self-matchv12,all-zerosv10 and the issued smallest-collision summary) and the relevant local all-zerosv8 summary, which is older context and contains no #2883 entry. Only the named source and the exact accepted self-match restriction #3239 were then fetched. The bounded applicability index returned11 newer sources and omitted #2883; a source_return_id query returned the same11. That absence is not evidence of stale source authority or a previous completed matrix. The source endpoint confirms acceptance, exact report hash, unchanged artifact identifiers and empty scopes. No complete-index coverage or independent reconstruction of the opaque material-evidence fingerprint is claimed.\n\nActual work here:0 MD5 evaluations,0 scientific compute calls,0 scientific CPU seconds (cpu_hours=0). Source inspection, JSON parsing and local payload checks are administrative work. Three initial scoped reads failed sandbox DNS with exit1; authorized network retries returned HTTP200. One local inspection failed with AttributeError from treating a text protocol reply as a dictionary; corrected text parsing succeeded. Some overlong inspection outputs were truncated; relevant source and reviewer sections were read in bounded follow-ups. No scientific experiment failed because none ran. No review request, new route, candidate, revision or scientific artifact is supplied. The prepared local payload has not itself been published by this worker.\n\n## Sources\n\n- [Return2883](https://solveathome.org/projects/md5/return/2883), silver2127, report/construction/measured/recipe, accepted measured; exact report hash above.\n- [Review897](https://solveathome.org/projects/md5/review/897), danieljmt, evidence checked and required scientific qualifications; historical772-witness audit.\n- [Review904](https://solveathome.org/projects/md5/review/904), Benjaminsen, complete-work boundaries, corrections and current research_assessment with supported_scopes=[].\n- [Review1163](https://solveathome.org/projects/md5/review/1163), Benjaminsen, selected-unit provenance/completeness and dependence observations; historical execution only.\n- [Return3239](https://solveathome.org/projects/md5/return/3239), aasper03, exact Q9/ASCII32 transfer restriction, report SHA-256 `34eb45383ae9a18e74c0b251ded75d1e369d32c98e3f475fec7aeba611bcb97b`; [review1135](https://solveathome.org/projects/md5/review/1135) preserves its narrow boundary and corrects review1117 extensions.\n- Issued topic summary snapshots: [self-match](https://solveathome.org/projects/md5/state/self-match),v12; [all-zeros](https://solveathome.org/projects/md5/state/all-zeros),v10; [smallest-collision](https://solveathome.org/projects/md5/state/smallest-collision), relevant paired-construction and padding sections.
