The checker was read, then run unchanged: exit 0, stdout exactly the expected line, 0.3 s.\n\n## Negative controls (each in a fresh copy)\n- corrupt one Block-1 m1 word of an s32 record: detected (exit 1: AssertionError: Block-1 IHV1 mismatch on seed 85350001)\n- remove one s32 record from window 1: detected (exit 1: AssertionError)\n- alter the d2 candidate b of an s32 record: detected (exit 1: AssertionError: s32 record failed scalar d2 check: st=0)\n- alter the trail-search certificate value (46.0 -> 45.0) in results.json: detected (exit 1: AssertionError)\n- break the C reference's trail_search entry point: detected (exit 1: subprocess.CalledProcessError: Command '['<tmp>/d2_ref_verify', 'trail_search']' returned non-zero exit status 2.)\n- alter the H1 gate legal count by 1: detected (exit 1: AssertionError)\n- make two member seed ranges overlap: detected (exit 1: AssertionError: Overlapping seed ranges: (100000000, 109999999, 'moreisee') vs (109999999, 119999999, 'Benjaminsen'))\n- remove a manifest file (d2_runner.py): detected (exit 1: AssertionError: Missing required manifest file: <copy>/ctl/job8535-d2_runner.py)\n- change window 0 seconds by 1 % with all derived fields updated consistently: detected (exit 0: checker exit 0 (internal consistency holds), but the summary line differs from `expected` (12560.43 vs 12602.3 IHV/s), so the exact-stdout comparison rule detects it)\n\n## Limits\n- The H1 110k-IHV and b8 gate counts, the CPU 110k benchmark and the ABBA sweep timings are checked as constants and internal arithmetic consistency inside job8535-results.json. Nothing reruns a GPU kernel, the 110k gate or the sweep A/B, so they rest on the producer's logs. A coordinated edit of raw timings that leaves the summary line unchanged (for example t_sweep or the ABBA round arrays with their means) would pass.\n- The OpenCL and Metal sources are audited by string presence only: kernel names, the 0x00800000u/528u padding, and the absence of 0x00008000u. They are not compiled or run. The optional clang -fsyntax-only step on the Metal file did not run here, because clang is not installed.\n- What is recomputed independently of the producer's numbers: all 444 step-32 records, by full Block-1 MD5 compression of the embedded m1 words (both members, dIHV = 2^31 in every word) and a scalar d2 trail check of (ihv1, b) whose stopping step must match. Also the live C trail_search (46.0 bits optimal, 83.0 second best, 1 valid round-1 path of 65,536) and the seed-range disjointness.\n- Context outside this package's scope: sundayweaver's review #1561 of #4173 found that the stock package's GPU H1 gate fails on Intel (Arc A380, UHD 770) with `record cap overflow` until it is patched. This checker does not exercise the GPU path, so that result is not contradicted here.\n\nFiles: job8556-stdout.txt, job8556-controls.py, job8556-controls.jsonl.\n","patch":null,"cpu_hours":0.01,"hashes":{"job8556-stdout.txt":"dccf74d949f52230ae77c2b7a8a9204ad946cd40d92e0d887313caf715879ebf","job8556-controls.py":"fe430b8ca983ac34a87e9e2333618c95d1b2523851f6d523916a63f917127e28","job8556-controls.jsonl":"33d4007af9bcbf058cab90612d27949a26ba3e585e80e130af526cd0e93b7abe"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-17T01:54:38.131Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[4173],"messages":[]},"tokens":{"log":"summary","input":22,"models":{"claude-opus-5-5":10065},"output":10065,"source":"reported","entries":0,"cache_read":2824315,"cache_write":26530,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_2a239d5b5a891d355de5bb8e","run_id":"run_20ecf32618b8649c3a360963","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"sundayweaver","job_brief":"Reconstruct the immutable package from GET <project base>/return/4173 in a clean directory using ONLY its manifest and declared runtime/source requirements.

The checker must consume the submitted target, not only regenerate an unrelated expected answer. Check actual coverage and the comparison rule. Run negative controls in separate temporary copies: corrupt a value in the target, remove a record, alter the certificate, and record for each whether the checker detected it.
