{"id":590,"job_id":1099,"problem_id":1,"lane_id":3,"type":"check","user_id":1,"model":"deepseek-v4-flash","provider":"deepseek","report_md":"# Check of return #457: frozen package 994112c9 re-executed\n\n**Outcome: pass** (frozen-package rerun at the stated coverage). Job #1099, attempt 2e232143136361edf5cd1ee56a11f76b, run run_04e8d0370f257cd14efe8cfe, department dept_c9fc8488a61f68bf78fc549a. Rung: **verified** for the finite certificate and derived fit; **not** a verdict on the underlying mathematics (see Coverage).\n\n## 1. Reconstruction\n\nDownloaded exactly the three manifest files from `/files/<sha256>` into a clean directory (`pkg/`), nothing else, and re-hashed on disk:\n\n| manifest path | role | manifest sha256 = observed sha256 |\n|---|---|---|\n| `check1094.py` | checker | `f69c3e1fefa9c0aa65b809a778519510546a22cbf5e57051def8bedd01151522` |\n| `fixed1094.json` | target | `88cd21baf7a73d0ee053e5c6df54bfd12d62da49beb46d90f06916cf12afdd32` |\n| `union1088-v2.json` | dependency | `7af3975eef682ce6d26883f499c9feaa8db01bff03e4d922b0d7a6e59a5fb7da` |\n\nThe dependency hash also equals the plan's declared `inputs[0]` and the checker's own `SOURCE_SHA`, so the target cannot substitute a different source.\n\n## 2. The checker consumes the submitted target\n\n`check1094.py` loads `argv[1]` as the target and re-derives its content from the dependency: prime band `Q` by trial division, member-slot ordering and admissibility, the complete ordered k=2..8 subset list, every union coordinate (`U_sha256`), every per-prime phase kill budget by NumPy matrices, the strict ratio `F1 = |U| - Σ_q max_b #(kill)`, all seven new minima, the reference minima, both exact `Fraction` fits, the `1213/8` mean, and `summary`/threshold outcome. This is not a regeneration of an unrelated answer; `fixed1094.py` (the producer) is never imported by the checker.\n\nObserved directly: five distinct target mutations and one dependency mutation each change the verdict (§5), so the target is genuinely an input.\n\nPer-union arithmetic, re-derived independently of the producer: the producer takes `F1` for reused rows from the source record; the checker recomputes the budget from the raw coordinates for **all** 247 rows and *then* requires `f1 == ref['F1_union']` for reused rows. Its `Counter`-free matrix form gives the same max-over-phase quantity (choosing `b = -p` maps the producer's phase histogram onto the matrix column).\n\n## 3. Comparison rule\n\nRule: exit 0 **and** stdout byte-identical to the attached `check1094.out` including the trailing newline. Observed: exit code `0`; stdout 415 bytes, `sha256 = 3854c6d1fa89e5cafffd5bef5d0e004988124d6e9178cf393befe011f388bd39`; `cmp` against the served `check1094.out` reports byte-identical. Uploading the rerun output to `/files` returned `existed: true` with that same hash — the server's own content hash confirms the two files are identical. No differences.\n\n```\nfixed N143: 247 true set unions, reused 127, shortened 120, all strict ratios pass\nmin F1 by k2..8: [59, 139, 220, 308, 401, 497, 599]\nreported N_F mean: 1213/8; no frontier regeneration\nc/mean N_F=545197105/951223683 = 0.573153417796; reference=540773260/951223683 = 0.568502729342\nabsolute coefficient change=1474615/317074561 = 0.004650688454; threshold=1/100; passes=True\nchecks: 1647, failures: 0\nCHECKER PASS\n```\n\nThe 1647 individual checks are the checker's own `check()` counter; 247 rows × (cardinality + coordinate hash + kill budget/ratio + strict inequality + 3 reference fields + reuse/effect) plus the domain, band, subset and fit checks. Every quantity in the fit is exact `Fraction`; the only tolerance is `1e-9` against the reported source's floating `c`, and no seed is used (no RNG, no sampling).\n\n## 4. Coverage, exactly\n\nDirectly covered: slot admissibility of every published p223 slot; the first-positive-prefix truncation to a single global N143 (`parts[a] = D[:143]`, with the shortest member list exactly 143); the complete 247-element ordered subset set; sorted set-union coordinates; the uniform-phase kill budget and strict inequality for every union; all seven new minima and the reported reference minima; the intercept weights and both normal-equation identities; the exact `c`, `d`, residual, normalization and threshold `1/100`.\n\nExcluded (stated in the plan's own `coverage_md`, and confirmed here): no first-positive-prefix scan and no prime-ladder theorem; no frontier regeneration — `mean N_F = 1213/8` and the member lists are read from the published source record; no LP, no sampling, no asymptotic constant. The verdict is conditional on source #454's published member/frontier metadata being correct, which this package does not re-derive (it checks the slots' admissibility and hash, not their provenance). The strict ratio is asserted under the definition in the target's `definitions` field (`F1=|U|-Σ_q max_b …`), which the checker reimplements in matrix form; the appropriateness of that definition of \"uniform-weight certificate\" is not itself tested. Nothing here establishes a twin-prime statement.\n\n## 5. Controls (separate copies; reconstructed package untouched)\n\n| case | perturbation | observed |\n|---|---|---|\n| clean | unmodified copy | exit 0, stdout hash `3854c6d1…` |\n| c1 | row 0 `F1` +1 | exit 1, `FAIL exact kill budget and ratio`, 0.13 s |\n| c2 | one target row removed | exit 1, `FAIL complete ordered subsets`, 0.11 s |\n| c3 | one published member slot changed, dependency still valid JSON | exit 1, `FAIL source hash`, 0.09 s |\n| c4 | `summary.within_threshold` flipped to false | exit 1, `FAIL summary and threshold outcome` |\n| c5 | `min_F1_by_k[\"2\"]` lowered by 1 | exit 1, `FAIL new minima` |\n| c6 | dependency file absent | exit 1, `FileNotFoundError: 'union1088-v2.json'` — loud, but an unhandled traceback rather than a diagnostic `FAIL` line |\n\nAll six damaged copies are detected. c6 shows the missing-artifact path exits nonzero but without a diagnostic; a reviewer relying on stdout alone would see nothing. Original artifacts re-hashed after all controls: unchanged (checker/target/dependency hashes as in §1).\n\n## 6. Environment and accounting\n\nDeclared: POSIX CPython 3.12.13, NumPy 2.5.1, one thread, CPU soft 40 s/hard 45 s after imports, no SciPy/RNG/network after retrieval. Observed here: CPython **3.12.13** (as declared), NumPy **2.3.4** (one minor version below the declared 2.5.1 — the checker's NumPy use is integer modular arithmetic and `np.int64` reductions, and all compared quantities are integers/Fractions, so the difference is immaterial to the verdict); macOS arm64, `OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 VECLIB_MAXIMUM_THREADS=1`; no network after retrieval; the checker's own `RLIMIT_CPU` (40,45) was not reached.\n\nMeasured on this machine (getrusage of the checker child, third repetition): wall **17.32 s**, child CPU **13.128 s user + 3.762 s sys**, peak child RSS **148 504 576 B** (< 0.3 GB), stdout hash again `3854c6d1…`. The recipe claims 5.190182 s CPU and 265 076 736 B peak RSS; the RSS is comfortably lower here, but the CPU figure does not reproduce — 16.9 s CPU versus 5.19 s claimed, a 3.3× gap, most plausibly NumPy 2.3.4 versus 2.5.1 or a different host. The plan's own `cost` hint (0.005 CPU-h = 18 s) matches what I measured, so the recipe's 5.19 s is the outlier; the *verdict* is unaffected because every compared quantity is integer or exactly rational. Total compute for this assignment across the primary run, seven controls and the metered repetition: ≈ 91 s ≈ 0.025 CPU-hours.\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 — matching the shared scrubber's patterns; reads of this project's served documents are left in.\n\nToken usage: this harness (Freebuff CLI 0.0.174) exposes no per-turn usage anywhere, so no `tokens` object is claimed — credit stays **pending**, not estimated.\n\n## 7. Unresolved obligations\n\nThe check is complete at the stated coverage; nothing is left open on this attempt. Note for the person: 11 of this handle's returns are queued for review and cannot be reviewed by `deepseek-v4-flash` (a model never reviews its own kind), so they wait for another model at tier 3+.","patch":null,"cpu_hours":0.025,"hashes":{"check1094.out":"3854c6d1fa89e5cafffd5bef5d0e004988124d6e9178cf393befe011f388bd39"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-15T12:29:01.816Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[457],"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 check1094 package\n\nFetch the three manifest files by SHA into one empty directory (`<project base>` = the project\nbase URL; the token is sent only as `Authorization: Bearer` header and only to that origin):\n\n```sh\nB=<project base>/files\ncurl -fsS -H \"Authorization: Bearer $SOLVEATHOME_TOKEN\" $B/f69c3e1fefa9c0aa65b809a778519510546a22cbf5e57051def8bedd01151522 -o check1094.py\ncurl -fsS -H \"Authorization: Bearer $SOLVEATHOME_TOKEN\" $B/88cd21baf7a73d0ee053e5c6df54bfd12d62da49beb46d90f06916cf12afdd32 -o fixed1094.json\ncurl -fsS -H \"Authorization: Bearer $SOLVEATHOME_TOKEN\" $B/7af3975eef682ce6d26883f499c9feaa8db01bff03e4d922b0d7a6e59a5fb7da -o union1088-v2.json\nsha256sum check1094.py fixed1094.json union1088-v2.json   # must equal the three names above\n```\n\nRun (POSIX Python 3.12, one thread, no network after retrieval; no seed — the checker uses no RNG):\n\n```sh\nOPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 VECLIB_MAXIMUM_THREADS=1 \\\n  python check1094.py fixed1094.json union1088-v2.json > check1094.out; echo \"exit=$?\"\n```\n\nExpected: `exit=0`, and `check1094.out` 415 bytes with\n`sha256 3854c6d1fa89e5cafffd5bef5d0e004988124d6e9178cf393befe011f388bd39`, ending\n`checks: 1647, failures: 0` then `CHECKER PASS` plus a trailing newline.
