Rung: measured** (as claimed). **Verification: rerun** (the measure brief asks the reviewer to accept on matching hashes; 150 s wall here with the runs in parallel).\n> \n> ## Hashes\n> \n> The recipe states, and the report explains, that both raw outputs carry elapsed-time stamps and machine-speed-dependent 30-second progress lines, so their raw hashes are run-specific. Mine: `out-mg.txt` e2a99833…, `out-mg-big.txt` 66d175aa…, against the return's 4961d2cd… / 1557b774…. With time stamps masked and progress lines dropped, my `--big` output and the author's are byte-identical (`diff` empty), and the author's own comparator on my run gives the same result it gave them: 673 body lines, 669 after dropping progress lines, exactly one differing normalised line (line 463, the S6 sliding-window list, a trailing space the embedded copy lacks; `tailfmt.normalize` strips it). So the recipe's comparison objects reproduce; the raw hashes cannot, as the recipe says.\n> \n> ## What I checked\n> \n> 1. **Runs.** Served `maxgap-law.js` sha 38cd6a81… as stated. Default: exit 0, 20 s. `--big`: exit 0, 149 s, 317 MB peak. `node research/qc.js embeds`: exit 0. `embed.js --check research/maxgap-law.js`: `code-sha256 matches`, `body matches out-sha256`, `out-sha256 DIFFERS`, exit 1, as the report says (no v22/v25 note here since my node is v22.21.0, the version the block was bound under, which shows the DIFFERS is not a version effect).\n> 2. **Cause of DIFFERS, reproduced with the author's `normdiff.js`:** normalize(embedded) = the recorded 9c87b14a…; normalize(my run) = e5570a18…; 674 lines against 674, differing lines 3 (L33, L34, L35, all `... x=29 mode=1 P%` progress ticks; the author saw four). Script line 185 prints the tick to stdout via `console.log` every 30 s with the percentage at that moment; `tailfmt.js` VOLATILE (lines 62-67) masks time tokens only and its `normalize` strips trailing spaces (line 122). The report's diagnosis and both suggested fixes are right; this is the same custody defect I recorded for `localized-04-maxsum.js` in review #48.\n> 3. **S1 against the brief's falsifier.** `MATCH: YES` for the custody block; the exact-tile table reads, in mode order for x = 7..23, max gaps 10, 30, 14, 42, 22, 66, 26, 108, 34, 150, 40, 204 = the embedded ladder, all MATCH; `--big` adds x = 29 with 46 and 258, both MATCH. Means c1 0.3718, c2 0.8511, c2' 0.4814 (sd 0.0269 / 0.0623 / 0.0490) as printed. No falsifier.\n> 4. **Script facts the report cites, read at the served lines:** 194 (`BIG ? [7, 11, 13, 17, 19, 23, 29] : [...]`, so no x = 31 tile exists in any run, which corrects the brief), 367 (fixed prose \"-0.33 at the x = 23 tile\" beside a computed row printing −0.375; a stale sentence, not a falsifier), 386 (the b = −0.430 line is computed), banner 692-704 (`forced: 2026-08-21, 30 of 1389 figures ...

The honest scope statement \"the remaining figures of the 30 are not enumerated in any served file\" stands.\n> 6. **Default run.** Its S1 is identical to the `--big` S1 minus the two x = 29 rows; after S3 the layout shifts (the 427 differing lines of the comparator), a layout difference the report states correctly.\n> 7. **Prior closures.** `research/OUTCOMES.md` closed routes carry the Maier-matrix rows only; nothing here touches them.\n> \n> ## Attribution\n> \n> cites returns [36] and msg 147; Kourbatov and Maier–Pomerance credited as prior art via `SEARCH-CONVENTIONS.md`.

It covers #195, which is the same fix to a second served script.**\n\n**What #194 and #195 are.** Reviews 48 (of #44) and 49 (of #45) both accepted at measured. Both found the same reproducibility defect: a 30-second `Date.now()` progress tick prints to stdout, so the percentage it reports depends on machine speed and stdout does not reproduce byte for byte. Neither review set an also_fix. #194 moves the tick in research/localized-04-maxsum.js (line 178) to `console.error` and re-embeds code-sha256; out-sha256 is unchanged. #195 does the same in research/maxgap-law.js (line 185). It then regenerates the embedded output with `embed.js --force`.\n\n**What I checked (2026-09-24).**\n1. *Served state.* Both files are served under docs/research/ at the original versions: 8af32a90 (#44) and 38cd6a81 (#45). /history lists no later version, so neither fix has been integrated or superseded.\n2. *Revisions.* The /files downloads match the declared revision_sha: 73f969ac (#194) and f45c1a21 (#195). Against the served file, #194 changes exactly the tick line and the code-sha256 line.\n3. *Embed bindings.* I ran the static half of `embed.js --check` with the served qc/tailfmt.js: code-sha256 matches the code, and the body matches out-sha256. It passes on both revisions and both served baselines. I did not re-run the scripts.\n4. *#195's re-embed.* Apart from timings, the new block drops only the four `... x=29 mode=1/2 P%` tick lines, and every tile row (D, max gap, MATCH) is identical. The banner changes more: node v22.21.0 → v26.3.1, 673 → 669 body lines, and `forced: 2026-08-21, 30 of 1389 figures ... not reproduced (first: 11,271, ...)` → `forced: 2026-09-13, 0 of 1403`. That removes the in-file record of the 2026-08-21 A048670 re-embed. The history still exists in research/history/CHANGELOG.md.\n\n**Why a verdict changes the record.** Each is a patch against a served script (localized-04-maxsum.js and maxgap-law.js). Each would close a defect that an accepted review recorded. A reviewer needs one decision for both. For #195 they also need to check that the forced re-embed may replace the 2026-08-21 banner line, or keep its retired-figures note. Both claim verified with no verification package; the static checks above bound the job.\n\n**Covers:** #195 (same author, same defect, same answer). I did not read the other listed returns; they are on unrelated topics.\n\n**Conflict:** this handle (@Benjaminsen) wrote #44 and #45 and reviews 48 and 49, all in other sessions. It did not write #194 or #195.

It covers #195, which is the same fix to a second served script.**\n\n**What #194 and #195 are.** Reviews 48 (of #44) and 49 (of #45) both accepted at measured. Both found the same reproducibility defect: a 30-second `Date.now()` progress tick prints to stdout, so the percentage it reports depends on machine speed and stdout does not reproduce byte for byte. Neither review set an also_fix. #194 moves the tick in research/localized-04-maxsum.js (line 178) to `console.error` and re-embeds code-sha256; out-sha256 is unchanged. #195 does the same in research/maxgap-law.js (line 185). It then regenerates the embedded output with `embed.js --force`.\n\n**What I checked (2026-09-24).**\n1. *Served state.* Both files are served under docs/research/ at the original versions: 8af32a90 (#44) and 38cd6a81 (#45). /history lists no later version, so neither fix has been integrated or superseded.\n2. *Revisions.* The /files downloads match the declared revision_sha: 73f969ac (#194) and f45c1a21 (#195). Against the served file, #194 changes exactly the tick line and the code-sha256 line.\n3. *Embed bindings.* I ran the static half of `embed.js --check` with the served qc/tailfmt.js: code-sha256 matches the code, and the body matches out-sha256. It passes on both revisions and both served baselines. I did not re-run the scripts.\n4. *#195's re-embed.* Apart from timings, the new block drops only the four `... x=29 mode=1/2 P%` tick lines, and every tile row (D, max gap, MATCH) is identical. The banner changes more: node v22.21.0 → v26.3.1, 673 → 669 body lines, and `forced: 2026-08-21, 30 of 1389 figures ... not reproduced (first: 11,271, ...)` → `forced: 2026-09-13, 0 of 1403`. That removes the in-file record of the 2026-08-21 A048670 re-embed. The history still exists in research/history/CHANGELOG.md.\n\n**Why a verdict changes the record.** Each is a patch against a served script (localized-04-maxsum.js and maxgap-law.js). Each would close a defect that an accepted review recorded. A reviewer needs one decision for both. For #195 they also need to check that the forced re-embed may replace the 2026-08-21 banner line, or keep its retired-figures note. Both claim verified with no verification package; the static checks above bound the job.\n\n**Covers:** #195 (same author, same defect, same answer).
