Job #1206, attempt\n17d207559b79f6f208953b8d2f86dc8b, run run_04e8d0370f257cd14efe8cfe, department\ndept_c9fc8488a61f68bf78fc549a. Rung: **verified** for this one frozen instance.\n\n## What was executed\n\nAll five manifest files were fetched by sha256 from `/files/<sha>` into an empty directory\n(`pkg/`) and re-hashed on disk: `check1205.py` 7268799b…, `target1205.py` 49cb8b8d…,\n`prereg1205.json` c1fcb739…, `target1205.csv` d47b4729…, `target1205.out` a7c7ba67… — all five\nbyte-exact. The declared command `python3 check1205.py` was then run exactly once in a clean copy\n(`run1/`), with `python3` resolving to CPython 3.12.13 (the declared POSIX 3.12.13, stdlib only).\n\n* exit code **0**, wall 0.305 s, CPU 0.245 s, peak RSS 25 608 192 B (25.6 MB); stderr empty.\n* stdout 212 bytes, byte-identical to the manifest's declared `expected` string\n  (sha256 `6e030bc6d223e1e5ef66d045a54d5c23def5e7308f90c252991b5b00049bb168`), and re-uploaded as\n  `check1205-rerun.out` (same sha, `existed: false`).\n* The package directory was re-hashed after the run: unchanged.\n\nThe checker consumes **both** supplied targets. It reads `target1205.csv` and `target1205.out`, runs\nthe pinned producer `target1205.py` on `prereg1205.json` in a fresh temporary directory, and requires\n(a) the recomputed CSV to equal the served CSV byte-for-byte and (b) the producer's entire stdout to\nequal the served `target1205.out` byte-for-byte (so the producer's own `rows`, `controls`,\n`target_only_points` and all four `summaries` are compared as bytes). Only after that gate does it\nprint `check: pass` with the two targets' hashes, which it recomputes from the served files.\n\n## Negative controls: 8 of 9 detected\n\nEach case ran in its own copy; `pkg/` was never modified (`controls-receipt-local.json`).\n\n| case | mutation | exit | diagnostic |\n|---|---|---|---|\n| c1 | one CSV `target_margin` changed | 1 | `AssertionError: CSV target mismatch` |\n| c2 | one CSV row removed | 1 | `AssertionError: CSV target mismatch` |\n| c3 | JSON `target_only_points` 0 → 1 | 1 | `AssertionError: JSON target mismatch` |\n| c4 | JSON summary `target_passes` 0 → 3 | 1 | `AssertionError: JSON target mismatch` |\n| c5 | `target1205.csv` absent | 1 | unhandled `FileNotFoundError`, stdout empty |\n| c6 | `target1205.out` absent | 1 | unhandled `FileNotFoundError`, stdout empty |\n| c7 | producer edited, comment only | **0** | passes — see below |\n| c8 | producer edited to change its JSON | 1 | `AssertionError: JSON target mismatch` |\n| c9 | prereg `divisors` narrowed to `[30]` | 1 | `AssertionError: CSV target mismatch` |\n\nc1–c4 are exactly the four controls the package's own `comparison` field promises. c5/c6 show a\nmissing target is fatal but diagnosed by a traceback rather than a stated FAIL class. c9 shows\n`prereg1205.json` is a live input, not decoration. c7 is the informative one: the checker executes\n`target1205.py` **from disk without pinning its hash**, so a behaviour-preserving edit still passes;\nonly the byte comparison catches a behaviour-changing one (c8). The manifest does pin that hash and\nthe on-disk file matches it, so the omission did not affect this run — but the check's own\n\"as-shipped code\" claim rests on the manifest, not on the checker.\n\n## Independent audit of the two targets (no package code imported)\n\n`structure_check.py` reads the targets as data and recomputes the whole grid from the definitions in\n`prereg1205.json`: W, D, N from trial division (W = 17# = 510510, 19# = 9699690; N = W/m), fiber\nmasks gcd(a(a+2), m) = 1, residual kernel products, per-fiber first/second moments by the pair\ndefinition, `balanced(M, N−z)`, margins, the z = 2 reflection-fixed rule, and the\n`a0 = (p+1) mod m` target fiber.\n\n* **All 1696 rows × 14 numeric cells reproduced exactly** (0 mismatches, 0 duplicate keys, header\n  equal to the declared column list); 1696 = 341×2 for p = 17 + 507×2 for p = 19, L = 1..next_prime(p)²−p−3.\n* Internal identities hold at every L: `Σ_a M_a = L·D`, `Σ_a S2_a = L·D + 2Σ_h (L−h)·whole_k[h]`\n  (whole-period expansion, recomputed independently), reflection `(M_a, S2_a) = (M_b, S2_b)` for\n  `b = (−a−L−1) mod m`, and every-fiber-pass ⇒ target-pass.\n* Shared primitives checked against brute force: the kernel product formula against literal residue\n  enumeration mod W = 210 for h = 0..8 (9/9 agree), and `balanced(M,N)` against exhaustive\n  minimisation for 52 (M, N) pairs (all agree).\n* The claim's counts reproduce by two routes: from the CSV's own margin columns, and from the\n  recomputation — **0 target passes, 0 every-fiber passes, 0 separations** in each of the four groups\n  (17/30, 17/210, 19/30, 19/210); the JSON `summaries`, `rows` and `target_only_points` agree.\n\n## Scope and what this does not say\n\n* The checker is a **reproducibility** check: it re-runs a producer that shares source with the\n  target's own producer and compares bytes. It does not verify the mathematics — the CRT moment\n  gates, the balanced-bound comparison, the reflection-orbit rule and the zero-budget rule are\n  re-executed, not proved. The producer's internal assertions do run (no `-O`), including\n  `Σ_a M_a = L·D`, `Σ_a S2_a = whole_s2` and the reflection equality, and the audit above adds an\n  independent recomputation of every cell.\n* The claim is a **negative** result: zero passes of either certificate. `check: pass` therefore\n  means \"the negative outcome reproduced\", **not** that any certificate succeeded. The frozen grid\n  never separates: in every one of the 1696 rows `failed_fibers` equals m (30 or 210), so every\n  window fails in every fiber; no margin is negative (least `max_fiber_margin` = 0, least\n  `target_margin` = 0), i.e. the second moment never falls below the balanced minimum. The\n  preregistration's success criterion (≥ 1 point with `target_margin < 0` and\n  `max_fiber_margin ≥ 0`) is not met, so the question it asks is answered **no** on this grid.\n* Bounded scope, taken from the manifest and confirmed here: p ∈ {17, 19}, m ∈ {30, 210}, every\n  integer L up to next_prime(p)²−p−3, exact analytic CRT moments only. No actual wheel/sieve profile,\n  no maximum-gap census, no earliest-twin computation, no infinitude or twin-prime statement; the\n  chosen-window quantifier and CRT conditioning are prior work, not established here. The frozen\n  configuration is one instance: nothing here bounds other p, m or L.\n* Two metadata notes, neither affecting the verdict: the package's own comparison would catch a\n  damaged target but reports failures as bare `AssertionError`s with empty stdout, and a missing\n  target as an unhandled `FileNotFoundError`; the checker prints its numbers from the served target\n  JSON rather than from the recomputed run (equivalent only because the byte gate precedes them).\n\n## Disclosure\n\nToken usage is **pending**: this harness exposes no usage accounting for the session, so none is\nreported or estimated. The transcript is this assignment's own log, taken from the local chat\nrecords for this run.","patch":null,"cpu_hours":0.0001,"hashes":{"check1205.py":"7268799b28bf894ea2f9a7e307ec974cbed6043600f351bcb6d9afead7c794f4","target1205.py":"49cb8b8dd25ca405b50c5e02b491f586c089e06c1e33a5c009734da97f099c87","target1205.csv":"d47b47299f6e63da57a7e0ddec00c1d8b0b6f2b572009ff7ded9ce1065dda0f4","target1205.out":"a7c7ba67301d8866f106ed503b2f65d52982c86afa11b305848749c8260ec379","prereg1205.json":"c1fcb739e92a19957c21cf1b8a512ef6d4e27124f1d5ee7f9cc428aa3afa87a4","check1205-rerun.out":"6e030bc6d223e1e5ef66d045a54d5c23def5e7308f90c252991b5b00049bb168"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-15T13:13:18.644Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[522],"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 check1205 package (job #1206, return #522)\n\n`<project base>` is the project base URL.
