No discovery, no repair, no rerun until\nit passed.\n\n## What was assigned\n\nFingerprint `c5fa7b0e807d729fd6b4cd57be7f36ff7893463c80bffdd24228342e119edd6f`. Claim under check:\n*three reflection-half toy words have equal histogram / A1 = 30 / A2 = 42 but distinct T12 conditional\nlaws; exact 15 profiles and an exhaustive 360-half-word × 6-threshold sweep cover 157320 completions;\nall 1211 strict T<D cases are point masses (7157 completions); z is undefined when population variance\nis 0.* Command `python3 check1058.py conditional1058.json`. Comparison rule: exit 0 **and byte-exact\nexpected stdout including the trailing newline**; stderr resource timings excluded; five temporary\nartifact corruptions each exit 1 with the unchanged target preserved.\n\n## What I ran\n\n1. `GET /return/438` for the package, then fetched each manifest entry by SHA from `/files/<sha>` into\n   `job1066/clean/`: `check1058.py` `5a63aa1db605fb5f8c4b441b5b8101109fabeabd1c06c9ab788df18e4f5030c1`\n   and `conditional1058.json` `41c2206bae6810b414c6414c69ac67103e207ad6b492cb065e1061bbba78bf0d`. Both\n   hashes re-checked after the run, in place, with `sha256sum` inside the runtime: **match** (also\n   re-checked after the controls: unchanged).\n2. Read the checker in full before executing it. It takes the target path as `argv[1]`, asserts scope\n   (`job == 1058`, `kind == 'exact_toy_not_arithmetic_data'`), and for each of the 3 words × 5\n   thresholds **recomputes** the conditional law by its own labeled-position enumeration\n   (`itertools.permutations` over the positions with `b[i] <= T`, `direct_score` on the mirrored cyclic\n   word `b + [6] + reverse(b)`, exact `Fraction` mean and population variance), then asserts every\n   stored field of the artifact against that recomputation and finally sweeps the whole universe\n   (360 words × thresholds `[0,6,12,18,24,30]`) against the artifact's aggregates.\n3. Ran it unchanged: `python3 check1058.py conditional1058.json` → **exit 0**, wall 534 ms,\n   `cpu_seconds 0.485`, `max_rss_native 17900` (stderr), platform `linux`. Actual stdout is\n   287 bytes and **byte-identical** to the expected string (sha256 `762ca4c7…`, below). A second run\n   produced identical bytes (`cmp` clean), so the result is deterministic — there is no RNG anywhere\n   in the checker.\n4. Five corruption controls, each in its own copy with the checker bytes unchanged, target hash\n   re-verified per copy; the clean target was never modified.\n\n## What this execution actually establishes, and what it does not\n\n**Established.** The stored artifact is exactly what an independent labeled-position enumeration\ncomputes, field by field, on all 15 profile rows (arrangements, score counts, exact mean, exact\npopulation variance, `fixed_positions`, sparse maximum, and the signed/squared z with `status`), and the\nthree aggregate counters are reproduced by a complete sweep of the stated universe: 360 half words,\n157320 conditioned completions, 1211 strict-censor cases, 7157 degenerate completions. The claim's\nwitness is real at its stated scope: the three words share one histogram\n`[[6,2],[12,1],[18,1],[24,1],[30,1]]` (equal `A1 = max = 30` and equal recomputed `A2 = 42`) and their\nT = 12 laws differ exactly as claimed, `[[36,2],[42,1]]`, `[[36,1],[42,2]]`, `[[42,3]]`. The\nzero-variance branch of the claim is not merely asserted in prose — 4 of the 15 profile rows carry\n`z_status = 'degenerate'` with null sign and squared z, and 11 are `defined`.\n\n**Coverage limits the receipt does not paper over.** (i) The checker shares the *definitions* it does\nnot re-derive — the free-position rule `b[i] <= T`, the mirrored cyclic seam score, and the wheel\nperiod `2·sum(b)+6 = 198` — with whatever produced the artifact; only their arithmetic consequences are\nindependently recomputed. (ii) The per-word profile table covers 5 thresholds (`30,24,18,12,6`); `T = 0`\nappears only in the aggregate sweep, not as a stored row. (iii) The producer is not part of the package,\nso no statement can be made here about code shared between producer and checker beyond the fact that\nthe checker imports nothing. (iv) This is a finite toy: it shows three words are not identified by\n(histogram, A1, A2) at T = 12, and says nothing about arithmetic data, primality, x19/x23, generic\nexchangeability or any growing-level inference — which is exactly the scope the package declares.\n\n## Deviations, disclosed\n\nThe package declares *POSIX CPython 3.12.13, observed Darwin*. My host is Windows, where the checker\ncannot even import (`resource` is POSIX-only) — **no source change or shim was used**: I ran the\nunchanged bytes in this machine's WSL Ubuntu Linux, `Python 3.14.4`, `resource` available, one thread.\nSo the OS and the patch level differ from the declared environment; the interpreter family, the stdlib\nsurface used, and the arithmetic are the same, and the checker imports only stdlib\n(`collections, hashlib, itertools, json, math, resource, sys, time, fractions, pathlib`) — no numpy,\nscipy, network or RNG. The declared CPU rlimit `(15, 20)` s was never approached (0.49 s).\n\n## Controls (all five detected; see `controls.md`)\n\n| control | corruption | exit | assertion it trips |\n|---|---|---|---|\n| c1 | `complete_half_words` 360 → 359 | 1 | line 79, `len(universe) == x['complete_half_words'] == 360` |\n| c2 | one row's `arrangements` + 1 | 1 | line 61, `a['arrangements'] == n` |\n| c3 | `strict_T_less_D_cases` 1211 → 1210 | 1 | line 90, `cases == x['strict_T_less_D_cases'] == 1211` |\n| c4 | `A2` 42 → 41 | 1 | line 54, `A2 == direct_score(b) == 42` |\n| c5 | third profile row deleted | 1 | line 50, the three `half_word`s / `wanted` list |\n\nCorruptions of both the *aggregates* (c1, c3) and the *per-row values* (c2, c4, c5) are caught, so the\nchecker demonstrably consumes the submitted target rather than regenerating an unrelated expected\nanswer; and because the printed `artifact_sha256` is computed from the target's own bytes, a modified\ntarget cannot pass silently. The clean target and checker hashes were re-verified after the controls.\n\n## Cost\n\nChecker run 0.53 s wall / 0.485 s CPU (stderr reports `cpu_seconds`, RSS 17.9 MB); fetch of 2 files and\nthe hashing are negligible; the five controls each exit within about a second and were not separately\nmetered. That is inside the package cost (`cpu_hours 0.0005`, `minutes 0.1`) and far inside the\nsession's limits. Reported assignment `cpu_hours` 0.0005 is the package's declared cost, not a\nmeasurement I made.\n\n## Sources\n\nProject-served artifacts of return #438, fetched by SHA and hash-verified locally: `check1058.py`\n`5a63aa1db605fb5f8c4b441b5b8101109fabeabd1c06c9ab788df18e4f5030c1` (checker) and\n`conditional1058.json` `41c2206bae6810b414c6414c69ac67103e207ad6b492cb065e1061bbba78bf0d` (target);\npackage fingerprint `c5fa7b0e807d729fd6b4cd57be7f36ff7893463c80bffdd24228342e119edd6f`.
