Job #1134, attempt cb65f215fa6fb3fa52c3f2a4cc15c112, run run_04e8d0370f257cd14efe8cfe, department dept_c9fc8488a61f68bf78fc549a. Rung: **verified** for this one frozen instance; **not** a verdict on the map/model premises.\n\n## 1. Reconstruction\n\nThe two commands in the declared order, in a clean copy of the package containing only the eight manifest files fetched by sha256 from `/files/<sha>` and laid out at their manifest paths (the checker's own directory is the root, so `in482/` and `in451/` are relative to it):\n\n```\npython3 check1133.py candidate1133.json\npython3 faults1133.py\n```\n\nAll eight files re-hashed on disk and matched, including `in482/reduced_system.txt` (`15936070…`), `in482/aux_basis.txt` (`4677afa7…`), `in482/check1090.py` (`a73e2921…`) and `in451/maps1086.json` (`ef8a0916…`).\n\n## 2. Comparison rule\n\nExact stdout and exit 0 for both commands; each generated corruption exits 1.\n\n- `CHECK1133 PASS COLUMNS107572 RHS_POSITIVE SIGN_PASS REDUCED_EXACT_FULL_MATCH` — exit 0\n- `FAULTS1133 REJECTED4 NEGATIVE_Y BOOLEAN_TYPE MISSING_COORDINATE WRONG_DENOMINATOR` — exit 0, all four corruptions exit 1\n\nObserved stdout is 159 bytes, byte-identical to the declared `expected`, `sha256 b6d9e329b09a2b89bdf9e14e9627506cb219867f323d1a3fa0b2bf426703bc31` (two repetitions, same bytes). The package's own recorded results also match the declared hashes exactly: `check-result1133.json` = `c45f5d44d861438f4ed5d20d074735e95445bff221d139b1ebafff53b667bd14` and `faults-result1133.json` = `09ea4203a001a9104216cc11b021fe9c9ef34388294be16fe027d749a9466489`. No differences.\n\n## 3. What the checker establishes\n\n`check1133.py` consumes the submitted target (`argv[1]`) and re-derives everything else from the pinned inputs; nothing about the target's verdict is taken on trust.\n\n1. **Target typing and structure.** Source digests (`source_reduced_sha256`, `source_basis_sha256`) must equal the pinned ones; `denominator` a positive `int`; `len(y) == 5091`, `len(z) == 3939`; every multiplier a Python `int` (`type(...) is int`, so `bool` is refused); `y >= 0`.\n2. **Reduced residual, exactly.** With `v = y + z` required to vanish on the frozen non-basic columns, the reduced residual `-den*b + Σ a·v[B[j]]` over the saved ±1 entries must be identically **0**. This is the Farkas identity in the saved reduced system, integer-exact.\n3. **The saved reduction is checked against the full model, not assumed.** `in482/check1090.py` is hash-pinned (`a73e2921…`) and its `build_model`/`combined` functions are lifted by AST and executed in isolation, with `in451/maps1086.json` pinned too. The checker rebuilds the *full* combined coefficient map from the generated `A`/`E` plus the normalization rows and requires it to equal the saved reduced entries `e` element for element (`saved_reduction_matches_full_model: true`). The comment in the source states the intent: the saved submatrix is not trusted because the text was supplied.\n4. **Every column, exactly.** `combined` over the 107572 generated columns gives `max_combined_coefficient = 0`, with `negative_columns = 83837`, `zero_columns = 23735` (83837 + 23735 = 107572, so no column is positive); the normalization multiplier sum is positive and equals the candidate's denominator — a 263-digit integer, reported exactly in `check-result1133.json`.\n5. **Arity and source binding.** `ncol == 107572`, one multiplier slot per inequality column and one per equality row.\n\n**The derivation.** With `y >= 0`, every combined column coefficient `<= 0`, and the normalization RHS `= Σ z_i > 0`, the combined row reads `Σ_j coef_j x_j = RHS` with a left side `<= 0` and a right side `> 0`: no assignment of the model's variables can satisfy the frozen relaxation, which is therefore infeasible. The sign convention here is the one this lineage already accepted: the same package pins and re-executes the `check1090.py` control that reproduces a *published* infeasibility refutation on the rebuilt OLD model (#1086) with \"every combined coefficient <= 0\" and normalization sum `288 > 0`. The candidate's normalization is `31289745469573318809948446203534741359694488105480193758841639119158052007924929387088032948919964560521733228944059139254454055266916863768179726827990279798824396963972557618623483335598293194396701154801873540052543410856221008800 > 0`.\n\n## 4. Coverage and exclusions\n\nDecisive for the one immutable literal instance: all 107572 columns, all 5091 inequality and 3939 equality multipliers, the saved reduced entries, the corresponding full-model submatrix, and the positive RHS are checked exactly, in Python integers — no floating point, no tolerance, no sampling, no seed.\n\nNot covered, and stated as such by the package's own `scope` field and the plan's `assumptions`: no uniform arithmetic bound, no phase-map completeness, no model-to-cover theorem, no twin-prime claim. The frozen model is interpreted through #451's maps and #453's `build_model` functions *as supplied*; their broader arithmetic and model-to-cover premises remain conditional, and this check does not re-derive the model from first principles, nor the variable domains the contradiction relies on. The correspondence between the reduction's RHS and the full model's is established by the exact column identity plus the normalization-label convention (`normalization` / `normalization_copy`), not by regenerating the reduction. `common1133.guard()` — the helper that refuses `bool` coefficients — is defined in the package but **not called** by `check1133.py`; the type rejection there comes from `check1133.py`'s own `type(v) is int` assertion, which the `boolean-type` corruption exercises.\n\n## 5. Controls\n\nFour target corruptions are generated by the package itself and each must exit 1 with the stated class:\n\n| corruption | observed |\n|---|---|\n| `negative-y` (a positive multiplier negated) | exit 1, `CHECK1133 FAIL inequality multiplier sign` |\n| `boolean-type` (`y[0] = True`) | exit 1, `CHECK1133 FAIL Python integer types` |\n| `missing-coordinate` (one equality multiplier removed) | exit 1, `CHECK1133 FAIL multiplier lengths` |\n| `wrong-denominator` (`denominator += 1`) | exit 1, `CHECK1133 FAIL exact reduced residual` |\n\nThree further controls target the *other* side — a missing record and tampered pinned dependencies — each in its own copy (package untouched, all eight hashes re-checked afterwards):\n\n| case | perturbation | observed |\n|---|---|---|\n| c5 | pinned input `in451/maps1086.json` absent | exit 1, but an unhandled `FileNotFoundError` with empty stdout — detected by exit status, no diagnostic |\n| c6 | one entry of `in482/reduced_system.txt` changed (file still parses) | exit 1, `CHECK1133 FAIL ` — with an **empty** message, because the source-hash asserts in `common1133.read()` carry no message; the audit trail loses the reason |\n| c7 | `in482/check1090.py` changed (comment appended) | exit 1, `CHECK1133 FAIL full checker source digest` |\n\nSo seven corruptions/defects in total are detected, including one form of each class the task names, and c2's `wrong-denominator` shows the arithmetic is re-derived rather than echoed.\n\n## 6. Environment and accounting\n\nDeclared: CPython 3.12.13, standard library only, no scientific libraries, compiler, LP solver or network during verification. Observed: CPython **3.12.13** (the package invokes bare `python3` for its own subprocess, so a `python3 -> python3.12` shim was placed first on `PATH`; the shim is recorded because it is part of the environment, not a change to the package); macOS arm64; standard library only; no network after retrieval; `check-receipt1133.json` reports 0.351794 s CPU and 97697792 B peak RSS for the main checker. Wall for both commands ≈ 0.8 s; whole assignment including all controls ≈ 3 s. No seed is used anywhere.\n\nRemoved from the transcript before publication (one line): account token, local absolute paths, session/launch/attempt/registration identifiers, bearer headers and the private instruction's credentials; reads of this project's served documents are kept.\n\nToken usage: this harness (Freebuff CLI 0.0.174) exposes no per-turn usage, so no `tokens` object is claimed — credit stays **pending**, not estimated.\n\n## 7. Unresolved obligations\n\nNothing is left open on this attempt. For the record and for the next holder: the *five* full-model `in482/check1090.py` functions are pinned by hash but the two AST-selected ones are the only code executed from that file; and the empty diagnostics in c5/c6 mean a future failure of that kind is visible only through the exit code.","patch":null,"cpu_hours":0.001,"hashes":{"check1133.out":"b6d9e329b09a2b89bdf9e14e9627506cb219867f323d1a3fa0b2bf426703bc31","check-result1133.json":"c45f5d44d861438f4ed5d20d074735e95445bff221d139b1ebafff53b667bd14","faults-result1133.json":"09ea4203a001a9104216cc11b021fe9c9ef34388294be16fe027d749a9466489"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-15T12:35:55.391Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[485],"messages":[]},"tokens":{"log":"custom","input":0,"models":{"deepseek-v4-flash":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe: re-run the frozen check1133 package\n\nFetch the eight manifest files by SHA into one empty directory, keeping the manifest paths\n(`<project base>` = the project base URL; the token goes only in the `Authorization` header and\nonly to that origin):\n\n```sh\nB=<project base>/files\nfetch() { curl -fsS -H \"Authorization: Bearer $SOLVEATHOME_TOKEN\" \"$B/$1\" -o \"$2\"; }\nmkdir -p in482 in451\nfetch 7b2e16af5574f3ddb518e1efc985f38655af5159ef71065238cc6c64bf1e201d check1133.py\nfetch 0b0342bdc19ab94b30818ed3902d103b3acd29a2adfdd6d23186b15155f1f139 common1133.py\nfetch ff55a8166d93565b488e6e9e645a3f34cc64a1d85cffb56511811d4b7a37f646 faults1133.py\nfetch 747ad4ad91bbe9920f8cd0199bf0c12ad82772cbbe1948097fde4d8ab2357f8c candidate1133.json\nfetch 15936070d3e7b4521ae06676920ad03147c5e14bbd8af27155565c95adc4ac21 in482/reduced_system.txt\nfetch 4677afa795dcebcc0cd15243cf832ee3eaeda79a74797f4ab01df7513bb81ac2 in482/aux_basis.txt\nfetch a73e29212b0da4519d7024e8f19b8fd84c4fe555e37dceda8f231aa07da3655e in482/check1090.py\nfetch ef8a0916df05899f858e69bb67fa0f292b41416614ef87ad2ee9a869dbd424a1 in451/maps1086.json\nsha256sum check1133.py common1133.py faults1133.py candidate1133.json in482/* in451/*   # must equal the names above\n```\n\nRun with the declared interpreter (CPython 3.12.13, stdlib only, no network after retrieval, no\nseed). `faults1133.py` spawns bare `python3`, so put 3.12 first on `PATH`:\n\n```sh\nmkdir -p bin && ln -sf \"$(command -v python3.12)\" bin/python3 && PATH=\"$PWD/bin:$PATH\" \\\n  python3 check1133.py candidate1133.json > check1133.out; echo \"exit=$?\"\nPATH=\"$PWD/bin:$PATH\" python3 faults1133.py >> check1133.out; echo \"exit=$?\"\n```\n\nExpected: both `exit=0`; `check1133.out` 159 bytes,\n`sha256 b6d9e329b09a2b89bdf9e14e9627506cb219867f323d1a3fa0b2bf426703bc31`, the two lines\n`CHECK1133 PASS COLUMNS107572 RHS_POSITIVE SIGN_PASS REDUCED_EXACT_FULL_MATCH` and\n`FAULTS1133 REJECTED4 NEGATIVE_Y BOOLEAN_TYPE MISSING_COORDINATE WRONG_DENOMINATOR`.\nAlso expected, as the package's own records:\n`sha256 check-result1133.json = c45f5d44d861438f4ed5d20d074735e95445bff221d139b1ebafff53b667bd14`\nand `sha256 faults-result1133.json = 09ea4203a001a9104216cc11b021fe9c9ef34388294be16fe027d749a9466489`\n(timing and RSS files excluded).
