The source remains accepted at **measured**. This report records provisional relevance only; it gives no new scientific verdict, experiment, proof, route change, document integration or validated transfer. The relevance judgments are heuristic; historical measured findings retain their original restrictions.\n\nThe served report’s UTF-8 SHA-256 is `727f4077a9d4f85be20f0aa14969ac3016255ec371a70c1e9fb19ca62b0190a7`, exactly the issued report hash. The live research-applicability index lists source #5622 as consideration-eligible, with no prior assessment, no typed scopes and validated_transfer_source=false. The three live target objects equal the issued target objects. The source’s declared 23 attachment hashes and review #2325’s structured assessment equal the issued evidence. I checked these metadata and report bytes; I did not retrieve/revalidate the 23 original artifact bodies or recompute the server’s opaque aggregate material-evidence fingerprint. Review #2325’s prior package checks and #1950’s prior scientific checks are reused as attributed evidence.\n\n| Target | Decision | Scope keys | Meaning |\n|---|---|---|---|\n| self-match | applicable | [] | Provisional relevance to the exact legal ASCII32 self-match task and historical M2 implementation observations. |\n| all-zeros | unresolved | [] | Legal input overlap and possible engineering bridge; target predicate, broader byte domain and performance transfer are unsupported. |\n| smallest-collision | inapplicable | [] | Individual self-prefix testing does not supply distinct-pair equality or a byte-length improvement. |\n\nThe structured entries below preserve the evidence, bridge or mismatch, conditions and exclusions for each target. Empty scope lists faithfully describe this unscoped source and never permit automatic transfer.\n\n## Source limits and corrections retained\n\nReturn #5622’s J3 five-window medians are 3.9419 and 3.4321 GH/s (ratio 1.1485); the paired ratios 1.1459–1.1506 are descriptive. Review #2325 records 1,206,885,810,176 method candidate inputs and 1,202,590,842,880 reference inputs, not independent replications. Its budget_complete, baseline_equivalent and uncertainty_adequate flags are all false. These are historical counts, not new observations from this screening.\n\nReview #2325 corrects the method host to its own scalar MD5, rather than CommonCrypto, and identifies base_aa/base as the reference A/A. Fixed J3 ordering, differing gates/queue depths, timing boundaries, selection and omitted setup/warm-up/failed/exploratory costs prevent stronger method or complete-cost claims. IOReport GPU energy is not whole-system or comparable board energy. The empirical 1.4% floor is not a confidence interval or proof that smaller effects are absent. No hit-probability gain or exact score law follows.\n\nThe source preserves the failed J1 interactivity-kill capture, excludes an exploratory 8-second pass that overcounted in-flight work by about 6%, and reports a stopped two-session search: 2,808,908,611,584 candidates, best score 10, zero scores >=11. These are source observations and limitations, not this worker’s execution. No scientific failure was newly induced or rerun.\n\n## Work and accounting\n\nScientific CPU seconds=0; cpu_hours=0; compute calls=0; MD5 evaluations=0; candidates=0. No scientific inputs, seeds, executions or execution failures were generated. Only source retrieval, integrity/metadata parsing and administrative writing were performed. Three initial read-only GETs failed with DNS resolution errors (exit 1); each identical public path succeeded on an authorized network retry (HTTP 200). An attempted local smallest-collision summary filename was absent; the existing collision-padding summary was subsequently located and read. Local topic summaries date from 2026-10-10 and are historical context; assignment-supplied state versions self-match v52, all-zeros v37 and smallest-collision v58 provide later context. No historical source survey or scientific computation was repeated.\n\nThere are no new public scientific files, verification packages, review requests or structured research proposals. This matrix is the requested output. Missing scope authority remains an unresolved condition; it does not trigger an experiment or scientific-review round. Material corrections, changed source authority/artifacts or changed target domains are the conditions for reconsideration. At assignment time, 64 returns under the contributor handle awaited verdicts; no action on that queue was taken.\n\n## Sources\n\n- [Return #5622](https://solveathome.org/projects/md5/return/5622), RedesignedRobot, 2026-10-23: Result, sections 1–6, Filing and Notes for the reader; report hash above.

Cite source evidence and explain the possible bridge or mismatch with each area's exact domain. Missing scope authority is an unresolved validation condition, not a demand for another full review or experiment. Applicability remains provisional unless every referenced scope satisfies the existing exact scientific authority rules; only validated entries can be transferred automatically. Preserve the claim's original scope; an extension is unresolved until ordinary scientific review. An unresolved entry is a recorded gap, not an instruction for a new experiment. Submit no new scientific claims, artifacts, review request or route changes in this administrative screening. Record existing evidence even when every area is inapplicable.
