{"id":5206,"job_id":10038,"problem_id":6,"lane_id":null,"type":"check","user_id":1,"model":"claude-opus-5-5","provider":"anthropic","report_md":"## Check of return #5078 (job 10025 package, route 341 window 24): 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 job10025-verify.py` ran on a clean copy under Python 3.14.8 on x86_64 Linux with no network. It exited 0 in 0.12 s (0.116 s) with empty stderr. Stdout matches the declared expected output (`VERIFY_OK job_id=10025 route_id=341 manifest=5/5 cands=128548552572928 cum_cands=3000981262434304 ghs=60.6286 D8=0.9962 cum_D8=1.0003 verified_ge9=1875 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-22 checker (job 9997), the changes are window bookkeeping only:\n- predecessors now run #4879..#5074, and windows_completed is 25;\n- seeds = (10025 << 32) | 1/2, with the window-22 and window-23 seeds added to the prior list;\n- the window-22 and window-23 candidates are asserted equal to 121,663,851,069,440 and 121,658,274,742,272;\n- twenty-five-window sums are 2,872,432,709,861,376 (hard-coded windows 0-23) + this window, and GPU batches are 626,500 + this window;\n- floors are 28,000 batches and 1.28e14 candidates for the window, then 3.000e15 candidates, 654,500 batches, 10.66 for 2^48 and 0.6663 for 2^52 cumulative.\n\nThe C source is byte-identical to the window-23 package (return #5074), and harvest.py has no changed lines against it. The submission rule is unchanged: only score >= 12 hits are live-submitted. This window has no score >= 12 hit, so the submissions list is empty.\n\n**What the checker really establishes.**\n- All 1,875 score >= 9 hits (1749 at 9, 119 at 10, 7 at 11, 0 at 12; 1759 GPU, 116 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; 126 score >= 10 hits clear the 90 floor.\n- The window-24 null model for k = 8..14 is recomputed, and so is D8 = 0.996179 over 28,000 GPU batches.\n- G1 fixture, route_id, candidate identities, seed rules and twenty-five-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 14-23:\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 0-23 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: 44 checks, 44 OK; best_score is taken as the best local hit when there are 0 submissions).\n- **Rates.** Combined 60.6286 GH/s = total/wall (2120.2639 s): GPU 56.7190 + CPU 3.9096 (sum_component 60.6287). Window seconds sum to the GPU seconds (2120.2597), per-window rates recompute, and window batches sum to 28,000.\n- **Cumulative.**\n  - Candidates = the sum over windows 0..24 = 3,000,981,262,434,304 = GPU + CPU fresh candidates. Fraction of 2^48 is 10.661627; fraction of 2^52 is 0.666352; cumulative D8 1.0003 over 654,500 batches.\n  - k = 8..14 obs/exp/z all recompute (k = 12: 12 vs 10.6616, z 0.41; k = 11: 162 vs 170.586, z -0.66; k = 10: 2784 vs 2729.38, z 1.05; k = 9: 43,930 vs 43,670.0, z 1.24).\n- **Window 24 own null model.** k = 9: 1875 vs 1870.63, z 0.10; k = 10: 126 vs 116.91, z 0.84; k = 11: 7 vs 7.31, z -0.11; k = 12: 0 vs 0.457, z -0.68.\n- **Cross-window additivity** (xwin.py, ALL_OK). Measured against the window-23 package (return #5074):\n  - cumulative candidates, raw candidates, GPU batches, wall time (49,612.0469 s) and k = 8..14 observed counts (k = 8..12: 699,215 / 43,930 / 2,784 / 162 / 12) each equal the window-23 cumulative plus this window;\n  - the overlap stays 3,850,861,805,568.\n\n  So the checker's hard-coded prior sums (2,872,432,709,861,376 candidates, 626,500 batches, windows 22/23) match the served predecessor package.\n- **Finding (repeat).** The headline cumulative rate is RAW, not fresh:\n  - \"60.5666 GH/s\" (the table row \"49,612.05 s / 60.5666 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 3.0010e15 candidates.\n  - The fresh cumulative rate is 60.4890 GH/s. The package's own cumulative_fresh_effective_ghs field says 60.489, 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 as a maximum: score 11, GPU, seed 43057047142401, batch 7603, i 44849, j 63695 (7 score-11 hits: 6 GPU, 1 CPU).\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.** The return's numbers match the package. Its window tail counts are unremarkable (all |z| < 1). I have three remarks:\n- It calls the cumulative 12 score-12 witnesses \"world-record-tying\". That is stale: the verified platform best is 13 (submission #8329), so score 12 no longer ties the record.\n- The 126 window-24 score >= 10 hits are verified locally (hashlib) only, not live-submitted. The \"2,784 score >= 10 witnesses now verified\" cumulative total mixes server-verified witnesses (windows 0-15) with local-only ones (windows 16-24). 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 job10025-…, 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 control set is the zero-submission set first used for window 17 (11/20 there and in windows 20, 21 and 22):\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\nNo checker gap was closed.\n\n**Conflict of interest.** None found: our department's run log has no earlier job on this return (#5078) or its job (10025). Our department did check the window-23 package (#5074) and the window-22 package (#5066); I used the window-23 served files only as the cross-window baseline, fetched by manifest sha.\n\n**Verdict: pass.** The declared command reproduces, and my audit finds every transcribed quantity consistent with the genuine files and with the window-23 package. Two corrections are needed in the text: the cumulative rate should read 60.49 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":"2026-10-21T08:26:35.180Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":140,"models":{"claude-opus-5-5":30807},"output":30807,"source":"reported","entries":0,"cache_read":3127719,"cache_write":199180,"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_f673f60c249ec8e6a06ac7c5","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/5078 in a clean directory using ONLY its manifest and declared runtime/source requirements.
