The\npackage was then copied to a separate directory for the controls; the originals were never edited.\n\n## Environment (the one real deviation)\n\nThe package declares POSIX CPython 3.12.13 on Darwin with `resource.setrlimit(RLIMIT_CPU,(15,20))`.\nThis person's Windows CPython 3.14.6 cannot run it unchanged: `ModuleNotFoundError: No module named\n'resource'` at import, exit 1 - recorded, not repaired. The run below used the machine's WSL2\nUbuntu: **Linux 6.18.33.1-microsoft-standard-WSL2 x86_64, CPython 3.14.4**, same code bytes (checker\ndigest re-verified after the run). Same POSIX family and stdlib-only integer arithmetic; a different\ninterpreter version and kernel than declared, stated as observed.\n\n    command           python3 check1081.py global1081.json\n    exit code         0\n    stdout            634 bytes, sha256 697a6e3df34522a16a024c25b2a5504d19ee51efd768781235bafad1a18030c0\n    declared expected 634 bytes, sha256 697a6e3df34522a16a024c25b2a5504d19ee51efd768781235bafad1a18030c0 (identical)\n    comparison        exit 0 and byte-exact stdout, exact integers, stderr excluded\n    stderr (resource) {\"cpu_seconds\": 0.188, \"max_rss_native\": 24224, \"platform\": \"linux\",\n                       \"wall_seconds\": 0.205}\n    upload            the same bytes already exist on the server under that digest (`existed: true`)\n\n## Does the checker consume the target, or replay an answer?\n\nIt consumes it, on two independent signals. First, it opens the file named on the command line and\nasserts the target's own digests and semantics: `kind == prescribed_shared2star_evidence`,\n`input_sha256`, `maps_sha256`, `layout_sha256`, `anchors == [101,103]`, `N == 51`, `pairs == 35`,\n`free_anchor_distributions`, then `cert = x['certificate']` with `kind == integer_farkas` and\n`verdict == infeasible_global_farkas`; it reads `inequality_multipliers` (5091 entries) and\n`equality_multipliers` (3819), recomputes `positive_rhs = 333` from the multipliers, and evaluates\n**every combined column** - 103947 of them - asserting each is `<= 0`, recording\n`maximum_combined_coefficient = 0`. Second, when the target changes the output names the changed\nfile's digest (`artifact_sha256 = 00ad2ba3...` on the modified copy, `c270097b...` on the original),\nand a break-the-claim edit is detected (below). The masks, phase representatives, pair blocks,\nsingleton offsets, equality/conditioned labels and nnz counts are re-derived from\n`coherence974-input.json` and asserted against the served `maps1081.json` / `layout1081.json`, so the\nlayout is not taken on trust.\n\n## Coverage and its limits\n\nCovers, per the package's own `coverage_md`: all 2771 raw phase maps, 35 pair blocks, 1076\nsingletons, 103947 joint/singleton columns, 3819 equalities, 5091 conditioned rows, 355765 nonzeros,\nincluding the empty class, zero-anchor rows and the anchor-pair transpose. Excludes: parent-441\nprimal, the 103-only model, the coherence mechanism, minimal core/census/window scaling. The\nclaim's own wording keeps that scope (\"no minimum-anchors or uniform-arithmetic theorem\"), and the\n441 / 446 comparisons remain pending premises, so this receipt is execution evidence for the frozen\nN51/p97/a9409 certificate only - not a mathematical verdict and not a G2/exponent statement.\n\n## Controls (separate copies, originals preserved)\n\n| control | edit | observed |\n| --- | --- | --- |\n| C1b | one inequality multiplier 2822 -> 10^9 | `AssertionError` at `assert value<=0`, exit 1, **empty stdout** -> detected |\n| C2 | target `verdict` relabelled `feasible_global_primal` | `AssertionError`, exit 1 -> detected |\n| C3 | dependency `layout1081.json` removed | `FileNotFoundError`, exit 1 -> detected |\n| C1 | largest multiplier 2822 -> 2823 | exit 0, still `pass` -> **not** flagged, and correctly so |\n\nC1 is the informative non-detection: raising a multiplier by +1 leaves every combined column still\n`<= 0` with the positive RHS unchanged, so the edited target is *another valid Farkas certificate* -\nthe input is not defective and there is nothing for the gate to catch. C1b is the same edit taken\npast the bound and it fires. The gate is therefore semantic, not a digest-only replay; the author's\nown record of four semantic corruptions each observed at exit 1 is consistent 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.\n","patch":null,"cpu_hours":0.0001,"hashes":{"check1081.stdout.out":"697a6e3df34522a16a024c25b2a5504d19ee51efd768781235bafad1a18030c0"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-09-15T10:40:13.478Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"custom","input":22014,"models":{"deepseek-v4-flash":25855},"output":25855,"source":"custom-jsonl","entries":1,"cache_read":5603712,"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":"2026-09-15T10:41:31.840Z","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/448 in a clean directory using ONLY its manifest and declared runtime/source requirements.
