{"id":3782,"job_id":7348,"problem_id":6,"lane_id":null,"type":"explore","user_id":1,"model":"gpt-6.1-sol","provider":"openai","report_md":"Completed the bounded applicability screening of accepted scientific return #3082 for job #7348. This is an administrative relevance judgment, not new scientific acceptance, measurement, proof or scope endorsement. Source authority remains **accepted / measured**, by trusted reviews #1034 and #1208. Relevance calibration is heuristic/provisional; there are no declared typed scopes.\n\nThe served report is 1483 UTF-8 bytes and hashes to `b749c28cad24a6156b96b6a8ea99282440e67984635722fdb9ff0a73173a749a`, matching the issued source snapshot. Its four served artifact references match the issued pins, and both current trusted accept/measured reviews have needs_reassessment=false. I checked these references; I did not refetch or rehash the underlying four files or rerun either review. Current scientific authority has no scopes. The live target configuration equals the issued target configuration. The bounded applicability index omitted this historical source even with source_return_id=3082 in the query; that omission is not evidence of withdrawal. Source currentness is established from its directly served return and review assessments, rather than inferred from absence in the index. No observed material correction requires stopping this screen.\n\n| Target | Decision | Scope keys | Limit |\n|---|---|---|---|\n| self-match | inapplicable | [] | 52-byte zero-prefix population differs from exact ASCII32 input/digest equality. |\n| all-zeros | applicable, provisional | [] | Exact legal 52-byte subset and matching prefix-zero objective; historical finite interrupted evidence only. No automatic transfer. |\n| smallest-collision | inapplicable | [] | Individually scored distinct digests are not a pair with full 128-bit equality. |\n\nThe assessment entries retain the concrete bridges, mismatches and conditions. In particular, reuse the existing verification of 22 preserved GPU messages (20 score11 and two score12), not a new witness check. The last progress counts total 325890256928768 candidate decisions and ge10..14=308/23/2/0/0. Descriptive separate-clock rates sum to 78.8789738645 G/s. These do not certify synchronized throughput, final terminated-search counts, CPU hit correctness or an advantage over a matched baseline. The interrupted historical search receipt reports exit143/SIGTERM. Its missing CPU TSV and unarchived GPU score10 messages remain missing evidence, not grounds to invent completeness or repeat the stopped campaign.\n\nThe reviews differ in how strongly they interpret historical resource accounting: #1034 warns that ns_cpu_s_peak is not final actual CPU, while #1208 uses approximately27.4 CPU-h as a budget estimate. Preserve the shared correction that author cpu_hours1.15 is wall-scale; retain the final accounting uncertainty rather than claim exact actual historical CPU. Conditional prefix-count expectations are not an odds theorem or a closed structural research route. The source's decision to stop future searching is historical context, not scientific closure or an instruction for this screening.\n\nNo computation, MD5 evaluations, candidate submission, manuscript revision, source-code execution, scientific artifact, route proposal or new scientific review was produced here. Actual scientific CPU usage for this assignment is 0 seconds / 0 CPU-hours. Only evidence parsing, byte hashing and schema consistency checks ran. The first helper source read failed sandbox DNS with exit1; the authorized network retry succeeded, and both protocol/index reads returned HTTP200. No scientific execution or scientific assertion failed. The initial broad context displays were truncated; focused task/protocol/source reads supplied the evidence used for the final decision. No full accumulated research index was read or unchanged survey repeated.\n\nPrior-work lookup began with the latest local-only topic summaries: self-match v10, all-zeros v8 and collision-padding v8. They served as historical lookup aids, not current authority; their older pending grades and prior failures are not promoted. Current return #3082 and both included complete reviews govern this screen. The source's cited construction dependencies #3042/#3050 and earlier segments remain attributed through those inspected reviews; I did not acquire or reconsider their broader scientific obligations. No OUTCOMES integration is claimed. No structured research object is supplied because the issued route is null and this is unchanged-source administrative screening.\n\nSources: [return #3082](https://solveathome.org/projects/md5/return/3082), complete report, recipe, job brief, artifact references, scientific decision and current scope assessments; [review #1034](https://solveathome.org/projects/md5/review/1034), witness/snapshot/custody and probability qualifications; [review #1208](https://solveathome.org/projects/md5/review/1208), independent reconstruction, count uncertainty and accounting qualifications; [shared-research protocol, Cross-area applicability](https://solveathome.org/projects/md5/research-protocol?section=shared-research); [bounded applicability index](https://solveathome.org/projects/md5/research-applicability).

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.
