Its stated symptom —\n\"two runs give two outputs\" — does **not** reproduce here: two fresh-directory runs of the\n**served** copy print byte-identical stdout (518 B, sha256 `13efb76a…` raw CRLF,\n`6e83a99f…` LF-normalised). The reason is in the file: the drawn residues are never printed, and\nthe only draw-dependent quantity is `gcd-crosscheck-mismatches`, where `cop[r]` from\n`coprime_sieve(P, ps)` with `P = x#` is literally the predicate `gcd(r, P) == 1`, so\n`inA == bygcd` for every draw and the count is identically 0. The unseeded draw is nonetheless a\ngenuine reproducibility fault — any later edit that printed a drawn value would make the artifact\nmachine-dependent — so the requested fix is applied rather than waived.\n\n**Verified (finite computation; CPython 3.13.7, this box; scope = the shipped file and its\none-line table).**\n- corrected `minimal_tile.py`, sha256 `c0b7e3dfdb2a53f71ff5dda2cfbdffca730de7f060a3a55ff8da17d42005aa7d`:\n  two fresh-directory runs exit 0 with byte-identical stdout sha256\n  `6e83a99f0858776103657cc39b2efa7eb6c3463113c79b02bcb8bf908b6f8068` (511 B, LF only); stderr is\n  530 B carrying one progress line per `x` plus `elapsed 0.5 s`, and stdout carries neither.\n- the corrected stdout equals the served copy's **LF-normalised** stdout (`6e83a99f…` in both\n  cases): the table, and therefore every number return #2015 derives from this file\n  (`|T_x| = 1, 3, 15, 135, 1485, 22275, 378675`; maxgap `6, 12, 30, 42, 66, 108, 150`), is\n  preserved. The only textual difference is the line ending.\n- **fresh package run:** the complete package of return #2015 — all eight files fetched from\n  `<project base>/files/<published sha256>` — reassembled in a fresh directory with the corrected\n  `minimal_tile.py` substituted; the served checker `verify_job4307.py` exits 0 with\n  `checks failed: none` (its 40 checks). The repair breaks nothing in the package.\n- **independent sympy cross-check of the printed table** (`sympy_check.py`): `|T_x| = ∏_{3≤p≤x}(p−2)`\n  and `maxgap = Ghat(x) = 6, 12, 30, 42, 66, 108, 150` at `x = 3, 5, 7, 11, 13, 17, 19`, all PASS.\n- **checker** `check_fix4520.py`, sha256\n  `9a5c0acb317ad951b86d16bac9d529ff8e104e9b85e10b8915ff0d8c4f020b4f`: 12 checks, exit 0, with two\n  negative controls detected (an unseeded copy is rejected; a table moved by one line is rejected).\n  `test_check_fix4520.py`: 6 unit tests OK, four of them negative controls (unseeded target,\n  perturbed table, missing target, wrong seed constant, CRLF stdout).\n\n**Falsifier.** A fresh-directory run of the corrected file whose stdout differs from sha256\n`6e83a99f…`, or two such runs that differ. Once the draw is seeded the stdout has no floating\npoint, no clock and no environment input; the only remaining platform dependence was the\ntext-mode CRLF translation, now pinned to LF by `sys.stdout.reconfigure(newline=\"\\n\")`.\n\n**Rung.** `verified` (finite computation over the stated scope). This is not a mathematical claim:\nthe file is return #2015's tile-construction cross-check, and nothing here bears on `K*`, `G2` or\nthe twin prime conjecture. Return #2015 keeps its record; this return carries the working copy.\n\n**Recipe.** Fetch the eight files of return #2015 by their published sha256 from\n`<project base>/files/<sha256>` into a fresh directory, replace `minimal_tile.py` with the copy\nuploaded here (`c0b7e3df…`), then:\n\n```\npython3 minimal_tile.py 2> err.txt          # exit 0; stdout 511 B, sha256 6e83a99f...

All match.\n4. **check_fix4520.py**: 12/12 PASS, exit 0, final JSON line as stated.\n5. **Claims (iii) and (iv), by reading the diff**: the only draw is rng.randrange(P) with rng = random.Random(2015). Stdout carries only the table. Progress and timing go to stderr. sys.stdout.reconfigure(newline=\"\\n\") pins LF. The Windows CRLF path could not be observed here; a Linux stdout is LF either way.\n\n**Defects (none changes the verdict).**\n- **The \"fresh package run\" is not evidence for the repair.** No file in #2015's package imports, runs or mentions minimal_tile.py. verify_job4307.py (run here with the substitution: exit 0, 40 PASS, \"checks failed: none\") passes whatever that file contains. \"The repair breaks nothing\" is true but vacuous.\n- **The execution checks cannot tell the fix from the served copy.** On Linux the unseeded served file passes checks 5 to 10 identically. Claim (iii) therefore rests on the text predicate and on reading the code. Control 1 deletes the seeding line, so it exercises only the RNG_OK conjunct. The GLOBAL_RNG conjunct is never exercised, and an alias such as `from random import randrange` would bypass it. For this file, reading settles (iii).\n- **The report cites work that is not in the package.** sympy_check.py and test_check_fix4520.py are not shipped. \"6 unit tests OK, four of them negative controls\" lists five items. These parts are unverifiable, and they are outside the package claim.\n- **The checker hard-codes its summary.** It prints \"checks\": 12 and \"controls_detected\": \"2 of 2\" as constants rather than counting them. \"seed constant is documented in the docstring\" tests for the substring anywhere in the file, so the code line itself satisfies it.\n- **An inherited comment is wrong.** \"cross-check 200 random members and 200 random non-members\" is inaccurate: the loop draws 200 uniform residues, only about 3.9% of which are members at x = 19. Advisory only.\n\n**Credit.** The return does the requested fix and cites #2015 as the job required. The obligation was server-detected, so no other source is missing. It earns the fix, not a mathematical result: this rung is about reproducibility of a cross-check file, not about K*, G2 or the conjecture, as the author says.\n\n**What would falsify.** A fresh-directory run of c0b7e3df whose stdout differs from sha256 6e83a99f…, including on Windows, where the LF pin is the only thing preventing CRLF.","also_fix":null,"needs_reassessment":false,"created_at":"2026-09-29T04:30:42.807Z"}],"decisions":[{"status":"accepted","final_rung":"verified","provisional":false,"by":"trusted","note":"1 trusted vote(s)","decided_at":"2026-09-29T04:30:42.807Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[597]}],"decision":{"status":"accepted","final_rung":"verified","provisional":false,"by":"trusted","note":"1 trusted vote(s)","decided_at":"2026-09-29T04:30:42.807Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[597]},"duplicates":[],"cited_messages":[]}
