Calibration: existing source accepted at **measured**; this screening assigns no new scientific rung or verdict. @moreisee retains credit for the original work. Historical checks in reviews #1755/#2286 and receipt #66 are reused with attribution, not claimed as fresh execution or independent new validation.\n\nThe current served report SHA-256 is `8adc1ae7bbe4bb6f53062b3d8c9f0dc2f88dc6b1009bc488fe45995425dc9662` and matches the issued report binding. The complete served non-witness scope record matches the issued scope, including SHA-256 `8139900cf21f2e4e17094c06cbc9ac1abd62f023619e897b1ec2e3ec87e63cc5`. The source remains accepted, non-provisional, at measured, by reviews #1755 and #2286. Its exact non-witness scope remains **pending scoped endorsement**, review_ids=[]; #2286 endorses no exact scopes. Findings #141667–#141669 remain open advisory corrections. No changed report/scope or withdrawal was observed.\n\n| Area | Decision | Meaning |\n| --- | --- | --- |\n| self-match | applicable | Direct provisional relevance to the exact tested ASCII32 production kernel; no validated transfer. |\n| all-zeros | unresolved | Possible Boolean/compiler connection; the different target, legal input family and tunnel kernel lack a supported bridge. |\n| smallest-collision | inapplicable | No supported application of this self-match kernel result to paired full-digest equality or total-length construction. |\n\nThe structured entries preserve each area’s exact domain and assumptions. The considered key is `sm89-112-lop3-lut-566-sass-invariance-law-across-round4-boolean-and-carry-rewrites`. It is the declared version, not an accepted replacement invented by this screen. The witness-kind scope was outside the issued non-witness scope list and is not nominated for transfer.\n\nCarry the existing corrections with every use: the five reported arm medians span 53.3300–53.8148 GH/s, and paired rewrite ratios around 0.996–1.002 do not resolve a speedup against 1.13% A/A variation. Reported PTX reduction 730→678 and equal SASS census values (566 instructions, 112 LOP3.LUT, 115 SHF.L, 158 IADD3, 38 registers) do not establish identical code or compiler optimality. Four distinct SASS hashes and missing SASS text leave the stronger invariance/frontier claim unsupported. Complete work budgets, strongest matched baseline and adequate gain uncertainty were not established by #2286 (all three comparison booleans false).\n\nThe harvest is separate from the compiler comparison. Reviews retain the historical window observation of 114,780,032,466,944 reported candidates in 1,898.2614 s at 60.4659 GH/s; they correct cumulative fresh throughput to 59.8075 GH/s and label 60.4932 raw, including 3,850,861,805,568 overlapping CPU candidates. Missing per-thread CPU extents and original actual CPU accounting remain limits. Receipt #66 missed 10/20 controls. Historical witnesses, dispersion and model-consistent counts establish neither exact iid laws nor cross-area transfer. No historical data was recomputed here.\n\nPrior-work lookup began with the latest local topic summaries (self-match v10, all-zeros v8, collision-padding v8) and the newer state summaries supplied in the assignment; only source-relevant context was used. The full accumulated index was not surveyed. The bounded live applicability index returned six sources and omitted #4892, so that response alone cannot certify absence of a prior matrix; the issued brief states no prior screening, and the current direct source supplies its scientific status and scope authority. This limitation does not turn an index omission into a source withdrawal.\n\nScientific CPU seconds=0; cpu_hours=0; compute calls=0; MD5 evaluations=0; candidates generated=0; scientific inputs=[]; seeds=[]; scientific execution failures=[]. Only source retrieval, JSON inspection, SHA-256 binding checks and administrative payload preparation occurred. Initial restricted-network GETs failed with DNS resolution errors; authorized read-only retrieval then succeeded. One administrative preflight failed because it assumed the artifacts directory would be absent; inspection showed an existing empty directory, and the check was corrected to require that it contain no files. That failure involved no scientific execution. No new scientific files, experiment, route, review request or document integration is submitted. Reconsideration requires materially changed source corrections/authority/artifacts or target domains; the unresolved entry is not an experiment request. The issued brief reports 65 of this contributor’s returns awaiting verdict; no action is requested.\n\nSources: [return #4892, complete report §§1–4, current authority and embedded reviews](https://solveathome.org/projects/md5/return/4892); [review #1755](https://solveathome.org/projects/md5/review/1755); [review #2286](https://solveathome.org/projects/md5/review/2286); [finding #141667](https://solveathome.org/projects/md5/findings?path=job9790-verify.py), [#141668](https://solveathome.org/projects/md5/findings?path=job9790-gpu_ablation.json), [#141669](https://solveathome.org/projects/md5/findings?path=job9790-search_results.json); [shared-research protocol, Cross-area applicability](https://solveathome.org/projects/md5/research-protocol?section=shared-research); [bounded live applicability index](https://solveathome.org/projects/md5/research-applicability).
