I read `job9643-verify.py` in full (stdlib only) and then ran the declared command `python3 -W error job9643-verify.py` once, as `python3 -I -W error` with cwd set to a clean copy. It exited 0 in 0.29 s with empty stderr. The stdout (1287 bytes, sha256 06db6954…) is identical to the declared expected output except for the single trailing newline that `print` adds. The parsed JSON is identical: status PASS, ge32 1790, ge48 38, new records hashed 550, pairs 2, and all four printed summaries.\n\n**Outcome: pass.** The declared comparison holds. The checker really consumes the target files:\n\n- It recomputes the 64-step MD5 (its own step function plus hashlib) on all 550 newly emitted harvest records, all 38 ge48 records, all 1790 ge32 records and both pairs (#6599, #6613).\n- It rebuilds per-run dx counters for the new runs, and the ge48 marginal and raw-m ladder counts.\n- It re-sums runs/q27/q29/dx totals over the batch table for 9 summary groups.\n\n**What is not established** (details in limits_md):\n\n1. **Claimed survival ladder.** `round4_step_ladders` (U3+S1 76→39→21→13→5→2→2; all paths 89→47→27→16→7→3→2) is never read. The checker's own ladder covers only the 38 raw-m records (38→26→15→10→5→3→2). The other dx48 events have no message in the package.\n2. **Run dedup.** No deduplication check: the \"428 unique runs\" equal the sum of `runs` over 34 batch rows, and nothing tests for uniqueness. Duplicate ge32/ge48 records are not rejected.\n3. **Gate 1 parity.** This is a comparison of two transcribed counter dicts. The OpenCL/C solver and pool_audit.py are never executed; they are only sha-printed.\n4. **Rates.** Rate fields (p_dx32/48_given_q29, their CIs, the ladder rates) are not recomputed. p_pair_given_dx48 is printed only after rounding, and the CP/Garwood intervals are computed but never compared.\n5. **Batch rows.** The 9643 batch row is not tied to the harvest run counters. My audit shows it does match (U3: 4 runs, q29 13666; S1: 8 runs, q29 172363). Prior batches are transcribed.\n\n**Controls.** I ran 20 single mutations, each on a fresh copy. All 20 were detected under the declared rule. However, 10 of them are caught only by a hash, either the prereg/harvest sha asserted from pooled.json or the printed `hashes` block. In a second \"sem\" mode, I refreshed the mutated file's sha in pooled.json and ignored the printed hashes. These 10 then pass silently:\n\n- Gate 1 coordinated edit\n- harvest run q29\n- ge48 dup\n- ge32 dup\n- ladder edit\n- p_pair\n- p_dx48 rate\n- U1 rate+CI\n- sources edit\n- prereg edit\n\nSo for those fields, the only protection is the exact output hash of pooled.json, not a semantic check. The other 10 still fail semantically (MD5 recompute, per-run dx counts, Gate 1 asymmetric edit, ge32 count, batch sums).\n\nMy extra audit of the genuine files found:\n\n- no duplicate messages in ge32 or ge48\n- ge48 ⊂ ge32, and every ge32 record with d_dx ≥ 48 is in ge48\n- the harvest sums match the 9643 batch rows\n","patch":null,"cpu_hours":0.01,"hashes":{},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-19T15:48:41.895Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":142,"models":{"claude-opus-5-5":38885},"output":38885,"source":"reported","entries":0,"cache_read":2834615,"cache_write":158736,"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_fe64e9890620b56ddd345691","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/4794 in a clean directory using ONLY its manifest and declared runtime/source requirements.
