It opens the file named on the command line and asserts the target's own labels and digests:\n   `job==1084`, `kind=='prescribed_single103star_evidence'`, `input_sha256`, `maps_sha256`,\n   `layout_sha256`, `anchors==[103]`, `N==51`, `pairs==18`, `free_anchor_distributions is True`,\n   then `cert['kind']=='rational_primal'` and `verdict=='feasible_global_primal'`, with\n   `cert is not None` rejected up front as \"not a certificate\".\n2. It reads the certificate out of that file - 131 `(index, numerator)` pairs, indices unique and\n   in range, numerators strict positive integers - and before that it re-derives the **entire model**\n   from `coherence974-input.json`: the 103-kill mask of every raw phase, the phase classes by equal\n   mask, least representatives, singleton offsets, the 18 pair blocks, the 1962 equality labels, the\n   2516 conditioned-row labels and the `E_nnz` / `A_nnz` / `csr_bytes` counts - then asserts the\n   served `maps1084.json` and `layout1084.json` equal its own derivation. The layout is not taken on\n   trust; `mapping['job']`, the source digest and the pair list are checked too.\n3. `artifact_sha256` in the output is the digest of the file actually read: `45d53d4a...` on the\n   original and `ff0a97d5...` on the deliberately altered copy (C6), and corrupted targets are\n   detected (C3, C4, C5).\n\n## Arithmetic that this execution actually establishes\n\nExact Python-integer arithmetic, no tolerance, no sampling:\n\n* all 19 normalization equalities: each prime's singleton masses sum to `T`;\n* all pair marginals both ways: for each of the 18 blocks and each class `a` of the first prime,\n  `sum_b mu(p,a;q,b) == v[singleton(p,a)]`, and symmetrically for `q`;\n* all 2516 conditioned rows: `-v[lambda_h(a)] + sum_{q!=h, b killing i} v[mu] >= 0` for every\n  103-class `a` and every slot `i` outside that class, with minimum 0;\n* 53351 variables = 1076 singleton + 52275 joint columns, 179106 matrix nonzeros, `T = 1935`,\n  131 positive primal entries.\n\nOne clause of the claim is **not printed by the checker**, so I checked it directly from the\nexecuted target using the checker's own re-derived maps: *\"lambda103 is a point mass at raw phase\n29.\"* It holds. Exactly one 103-singleton index is positive - index 68 = `singles[103] + 16`,\ni.e. representative **29**, whose class is precisely the raw phase `{29}` - and it carries mass\n1935 = `T`. No other 103-class has any mass. Every clause of the frozen claim is therefore supported\nby this execution except the ones the package itself excludes.\n\n## Coverage and its limits\n\nCovers, per the package's own `coverage_md` and confirmed here: all 2771 raw phase maps, 18 pair\nblocks, 1076 singletons, 53351 columns, 1962 equalities, 2516 conditioned rows, 179106 nonzeros,\nincluding empty phase classes, zero-mass anchor rows and the anchor-pair transpose. Excludes:\npending 441 (single101-star) and 448 (shared two-star Farkas) - declared conditional comparative\npremises, not read in this execution - plus any actual-cover, census-completeness, all-103-branch,\nminimum-anchor, compact-dual, arithmetic-window and exponent/infinitude statement. stderr is\nexcluded from the comparison. There are no seeds: nothing here is sampled.\n\nA structural caveat that limits what agreement means: the checker is standalone stdlib and imports\nno producer code, but it shares the served input and the producer's *conventions* - the variable\noffset formula, the one-hot phase cover, inverse aggregation and representative lift. Those\nsemantics are declared assumptions taken from the package, not re-derived here. So this is\nimplementation-consistency evidence across an independent re-derivation of the layout, at the stated\nscope - not an independent mathematical verdict, and not a statement about any phase cover.\n\n## Controls (separate copies; originals preserved)\n\n| control | edit | observed | expected? |\n| --- | --- | --- | --- |\n| C0 | byte-identical copy, no damage | exit 0, same stdout, `artifact_sha256 45d53d4a...` | yes - control on the control |\n| C1 | declared dependency `coherence974-input.json` removed | `FileNotFoundError`, exit 1, empty stdout | yes - detected |\n| C2 | dependency `maps1084.json` bytes altered (job relabelled 9999) | `AssertionError`, exit 1, empty stdout | yes - detected |\n| C3 | target: one primal numerator incremented by +1 | `AssertionError`, exit 1, empty stdout | yes - detected |\n| C4 | target: `verdict` relabelled `infeasible_global_farkas` | `AssertionError`, exit 1, empty stdout | yes - detected |\n| C5 | target: `T` incremented by +1, entries untouched | `AssertionError`, exit 1, empty stdout | yes - detected |\n| C6 | target: a *different but still valid* primal (all numerators and `T` x 2) | exit 0, `pass`, `T 3870`, `artifact_sha256 ff0a97d5...` | yes - correctly **not** flagged |\n\nC6 is the informative non-detection: scaling a feasible primal preserves feasibility, so the edited\nfile is another valid certificate and there is nothing for the gate to catch - while the output's\n`artifact_sha256` follows the changed file, so the checker is reading the target rather than replaying\na stored answer. C3, C4 and C5 are the break-the-claim edits and all three fire. The gate is\nsemantic, and the author's own record of four semantic corruptions each observed at exit 1 is\nconsistent with what I see.\n\n## Verdict\n\n`pass`, at the stated scope, from one run of the unchanged checker with the required controls. No\nrepair was attempted, no rerun to force agreement, and no claim beyond the package's scope is\nendorsed: this is a worker-reported execution receipt for the frozen single103-star certificate, not\na mathematical verdict and not a statement about actual phase covers.\n","patch":null,"cpu_hours":0.0001,"hashes":{"check1084.stdout.out":"79048c46269526d9432ddbdb4c35bef0fe005278f090b6d5427654581f1dfbb6"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-09-15T10:46:06.307Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"custom","input":112605,"models":{"deepseek-v4-flash":50146},"output":50146,"source":"custom-jsonl","entries":1,"cache_read":6748928,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"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":"max","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":"2026-09-15T10:49:13.237Z","file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_9e3c846778a19c71137dde42","run_id":"run_1b555656cba19bf7bbd26ca5","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"maxime-fleury","job_brief":"Reconstruct the immutable package from GET <project base>/return/449 in a clean directory using ONLY its manifest and declared runtime/source requirements.
