{"id":5136,"job_id":9965,"problem_id":6,"lane_id":null,"type":"check","user_id":1,"model":"claude-opus-5-5","provider":"anthropic","report_md":"## Check of return #5036 (job 9958 package, route 341 window 17): pass\n\n**Run.** I fetched all 6 manifest files (the checker plus 5 targets) from /files, and every sha256 matched. The declared command `python3 -W error job9958-verify.py` ran on a clean copy under Python 3.14.8 on x86_64 Linux with no network. It exited 0 in 0.1 s with empty stderr. Stdout matches the declared expected output (`VERIFY_OK job_id=9958 route_id=341 manifest=5/5 cands=121660765110272 cum_cands=2142494470963200 ghs=60.6011 D8=1.0158 cum_D8=1.0035 verified_ge9=1809 submissions=0 best_score=11`). The only byte difference is the trailing newline from print(), which the declared expected string leaves out. Compared with the window-16 checker (job 9952), the changes are window bookkeeping only:\n- predecessors now include #5031, and windows_completed is 18;\n- seeds = (9958 << 32) | 1/2, with the window-16 seeds added to the prior list;\n- window16_job9952_candidates is asserted equal to 121,690,322,370,560;\n- eighteen-window sums are 2,020,833,705,852,928 (hard-coded windows 0-16) + this window, and GPU batches are 441,000 + this window;\n- floors are 26,500 batches and 1.21e14 candidates for the window, then 2.142e15 candidates, 467,500 batches, 7.60 for 2^48 and 0.4756 for 2^52 cumulative.\n\nThe submission rule is unchanged from window 16: only score >= 12 hits are live-submitted. This window has no score >= 12 hit, so the package has 0 submissions and the count/membership rules are checked on an empty set.\n\n**What the checker really establishes.**\n- All 1,809 score >= 9 hits (1686 at 9, 114 at 10, 9 at 11, 0 at 12; 1699 GPU, 110 CPU) and the eq8 samples are rebuilt from (source, seed, batch, i, j) and re-hashed with hashlib.md5. Score, digest and the absence of duplicate candidates are tested; 123 score >= 10 hits clear the 90 floor.\n- The window-17 null model for k = 8..14 is recomputed, and so is D8 = 1.015792 over 26,500 GPU batches.\n- G1 fixture, route_id, candidate identities, seed rules and eighteen-window bookkeeping are asserted.\n- Submissions: 0 live submissions = 0 score >= 12 hits.\n\n**What it only transcribes or skips.** These are the same gaps as in windows 14-16:\n- **Throughput.** Only combined >= 60.0 is checked; wall_seconds and the component rates are never read.\n- **SASS.** The SASS counts are constant asserts.\n- **Cumulative pooling.**\n  - Cumulative obs/z is only checked as |z| < 3, and cumulative D8 is only a range check.\n  - The window 0-16 sums are hard-coded.\n  - Raw candidates and both cumulative rates are never read.\n- **Hit provenance.** Hit seed membership and score >= 9 are not asserted.\n- **Submission summary.** The top-level fields (total_submitted, score_12_count, best_score, submission_ids) and min_submitted_score are never read. Only the submissions list is checked.\n- **best_hit.** best_score is printed from best_hit.score and is never recomputed from hits_ge9. A score-10 record labelled 11 prints an identical line and passes silently.\n- **Sources.** The producers and the prereg are checked for existence only.\n\n**Independent audit** (audit.py: 43 checks, 43 OK; best_score is taken as the best local hit when there are 0 submissions).\n- **Rates.** Combined 60.6011 GH/s = total/wall (2007.5656 s): GPU 56.6939 + CPU 3.9073 (sum_component 60.6012). Window seconds sum to the GPU seconds (2007.5625 vs 2007.5628), per-window rates recompute, and window batches sum to 26,500.\n- **Cumulative.**\n  - Candidates = the sum over windows 0..17 = 2,142,494,470,963,200 = GPU + CPU fresh candidates. Fraction of 2^48 is 7.611669; fraction of 2^52 is 0.475729; cumulative D8 1.003512 over 467,500 batches.\n  - k = 8..14 obs/exp/z all recompute (k = 12: 9 vs 7.612, z 0.50; k = 11: 112 vs 121.79, z -0.89; k = 10: 1927 vs 1948.59, z -0.49; k = 9: 31,385 vs 31,177.4, z 1.18).\n- **Window 17 own null model.** k = 9: 1809 vs 1770.40, z 0.92; k = 10: 123 vs 110.65, z 1.17; k = 11: 9 vs 6.92, z 0.79; k = 12: 0 vs 0.432, z -0.66.\n- **Cross-window additivity** (xwin.py, ALL_OK). Measured against the window-16 package (return #5031):\n  - cumulative candidates, raw candidates, GPU batches, wall time (35,450.0699 s) and k = 8..14 observed counts (k = 8..12: 499,413 / 31,385 / 1,927 / 112 / 9) each equal the window-16 cumulative plus this window;\n  - the overlap stays 3,850,861,805,568.\n\n  So the checker's hard-coded prior sums (2,020,833,705,852,928 candidates, 441,000 batches, window 16 = 121,690,322,370,560) match the served predecessor package.\n- **Finding (repeat).** The headline cumulative rate is RAW, not fresh:\n  - \"60.5456 GH/s\" (the table row \"35,450.07 s / 60.5456 GH/s\") is raw candidates divided by wall time. Raw candidates include 3,850,861,805,568 non-fresh CPU overlap candidates.\n  - The return pairs this rate with the fresh 2.1425e15 candidates.\n  - The fresh cumulative rate is 60.4370 GH/s. The package's own cumulative_fresh_effective_ghs field says 60.437, but the return text never quotes it.\n- **Hits.** Every hit seed is a campaign seed and every hit has score >= 9. Tail counts equal the cum_counts. best_hit recomputes: score 11, GPU, seed 42769284333569, batch 298 (9 score-11 hits, all GPU).\n- **Submissions.** The list is empty, total_submitted 0, submission_ids empty, min_submitted_score 12. This is consistent with 0 score >= 12 hits.\n\n**Return text.** This return's report_md is current window-17 text and matches the package numbers, with three remarks:\n- It calls the cumulative 9 score-12 witnesses \"world-record-tying\". That is stale: the verified platform best is now 13 (submission #8329, 2026-10-20), so score 12 no longer ties the record.\n- The 123 window-17 score >= 10 hits are verified locally (hashlib) only, not live-submitted. The \"1,927 verified score >= 10\" cumulative total mixes server-verified witnesses (windows 0-15) with local-only ones (windows 16-17). It should say which is which.\n- The return's files list still names the C source job9787-selfmatch_nvtd_bcast.c, while the manifest path is job9958-…, with the same sha 66aba7d7….\n\n**Negative controls.** I ran 20 single mutations, each on a fresh copy. 11 were detected, all by assertion exit. 9 passed silently (see controls). The submission controls were redesigned for the zero-submission package:\n- a submission appended for a genuine score-11 hit labelled 12, with the top-level summary updated: detected by the count rule;\n- a hit relabelled 12 together with a matching submission: detected by the hit re-hash;\n- the top-level summary alone edited (list kept empty): passes;\n- min_submitted_score changed from 12 to 9: passes.\n\nSo 11/20 is not directly comparable with window 16's 12/20. No checker gap was closed.\n\n**Conflict of interest.** An earlier upkeep job (9966) in our department promoted this return into the project state summary. I did this check independently and re-derived every figure from the package files.\n\n**Verdict: pass.** The declared command reproduces, and my audit finds every transcribed quantity consistent with the genuine files and with the window-16 package. Two corrections are needed in the text: the cumulative rate should read 60.44 GH/s fresh, and the score-12 witnesses no longer tie the record. The checker should recompute best_hit from hits_ge9, compare the submission summary fields with the list, and assert hit seed membership.\n","patch":null,"cpu_hours":0.01,"hashes":{},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-21T01:26:47.367Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":166,"models":{"claude-opus-5-5":32676},"output":32676,"source":"reported","entries":0,"cache_read":3611666,"cache_write":161368,"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_da55f23c995cabb5136f4e91","run_id":"run_a737da841b930ce3861fec14","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":"Benjaminsen","job_brief":"Reconstruct the immutable package from GET <project base>/return/5036 in a clean directory using ONLY its manifest and declared runtime/source requirements.
