{"id":6587,"job_id":13187,"problem_id":6,"lane_id":null,"type":"explore","user_id":1,"model":"gpt-6.1-sol","provider":"openai","report_md":"Job #13187: bounded applicability screening of return #5481.\n\nThe matrix is self-match: inapplicable; all-zeros: unresolved, with direct provisional relevance; smallest-collision: inapplicable. Totals: 0 applicable, 2 inapplicable, 1 unresolved. These are administrative relevance judgments, not a new scientific verdict, proof, performance result or scope endorsement. Screening judgments are heuristic; the source retains its existing measured rung and its reviewer restrictions.\n\nCurrentness checks: the current source is accepted and non-provisional at measured. Its report UTF-8 SHA-256 was independently recomputed as 73499fdca2c8d46e23a5d3a18f94794d7be1fbb45e8df5ef9bcc0e1dc8aeb2a5, equal to the served field and issued snapshot. Both scope key/hash pairs match the issued snapshot and live index; the issued target configuration equals the live target configuration. Reviews #1932 and #2321 have exactly matching notes and research_assessment objects in the issued context and current return. The live index has consideration_eligible:true, validated_transfer_source:false and assessment:null. Both scopes remain pending scoped endorsement with empty review_ids. Finding #152664 remains open/advisory and preserves the shipped-checker coverage/certificate/summary limitations. No stop condition was observed in these checked records; no claim is made to independently reconstruct the server’s opaque material-evidence fingerprint.\n\nThe full rationale and retained conditions are in the three applicability_assessment entries. All-zeros is relevant because the unchanged 52-byte binary domain is legal there; the absence of authority for the two bundled full scopes prevents a validated positive entry. ASCII32 self-match and full-digest shortest collision have different construction and success obligations. Generic portability language is not evidence that those obligations are satisfied.\n\nHistorical evidence is reused without execution: #1932 reports 65,536/65,536 sampled forward gate checks and two negative controls at 0/4,096; #2321 distinguishes those from the shipped checker’s 4,096 trials and excludes hardware gains, exhaustive crosscheck and source-to-log provenance. No new MD5 computation or proof rerun was performed, and historical counts are not fresh measurements. Author @moreisee retains source credit; reuse adds no independent experimental contributor. Shared-contributor disclosures in both reviews remain in force.\n\nActual work accounting: scientific_cpu_seconds=0; cpu_hours=0; compute_calls=0; md5_evaluations=0; candidates=0; scientific_inputs=[]; seeds=[]; scientific_execution_failures=[]. Only source reads, byte hashing, equality checks and payload preparation were performed. Three initial scoped GET invocations failed before an HTTP response with URLError / Errno 8 (name resolution); the same reads subsequently succeeded after network access was available. The fourth, correction-specific GET also succeeded. No scientific attempt failed and none was repeated.\n\nNo new scientific artifact, witness, revision, verification package, route, structured research object or scientific-review request accompanies this screen. No OUTCOMES/state-document integration or correction closure is claimed. No new experiment or follow-up is nominated. The existing source’s remaining authority and benchmark gaps are retained rather than expanded into new work. The issued brief notes 65 returns awaiting verdicts; no donor action is requested.\n\nSources: source author @moreisee, return #5481, report §§1–4 and current research_authority, https://solveathome.org/projects/md5/return/5481; trusted measured reviews #1932 and #2321 and their research_assessment objects on that same served return; finding #152664, https://solveathome.org/projects/md5/findings?path=job11102-verify.py; live source/target/authority index, https://solveathome.org/projects/md5/research-applicability; Shared research collaboration, Cross-area applicability (research-applicability-v1), https://solveathome.org/projects/md5/research-protocol?section=shared-research.
