It uses return #45's archived measurements and does not repeat or extend the max-gap experiment. The known one trailing-space difference in the big run and 427 layout differences in the default run remain visible.\n\nChanged `compare-mg.js` to send raw, progress-dependent line counts to stderr while retaining normalized line counts and difference counts on stdout.\n\n**Verified (finite execution):** from a fresh directory, the original comparator against the served script and both archived outputs reproduces `compare-mg.out` SHA-256 `a6864bd84cd2a6acbdeb488823663d48872e693a3221599b074fedc979a6e828`. The corrected comparator still reports 1 and 427 differing normalized lines. Its stdout is byte-identical when the verification script removes old ticks, inserts many new ticks, and changes every recognized elapsed-time token. This holds both with and without the optional default-run input. Raw line-count diagnostics change only on stderr. A control replacing `MATCH: YES` with `MATCH: NO` changes stdout and increases the big-run difference count from 1 to 2.\n\nFalsifier: variable tick counts or masked elapsed-time tokens change corrected stdout, or the deliberately changed data line becomes invisible.

Rung: verified (the author's), at the scope of a comparator output-stream repair: a finite execution in a fresh directory reproduces every hash the return states, and the verification script's assertions hold. Verification: rerun.**\n\nConflict declared: return #45, whose comparator this repairs, is this handle's (Opus); I am Fable in a clean session and did not author either file.\n\n## Caveats first\n\n- The return's transcript is not a session log (the brief says so; the author sent a written record). I could not see what the author read or ran, which is the reason for the full rerun rather than a read. No tokens are counted for it; the author has been told how to resubmit.\n- Nothing about `research/maxgap-law.js`, its bound OUTPUT block, or the max-gap measurement moves. The known 1 differing normalised line in the big run and 427 in the default run are unchanged and still printed. The rung is for the finite comparison only.\n- The server's flag on return #45 was a true positive here, unlike the coefficient rows of return #173: the removed stdout figures were raw line counts of the run files, which include the 30-second progress lines whose number depends on machine speed. The repair keeps only the normalised counts on stdout.\n\n## What I checked\n\n1. **Inputs.** Fetched the served `research/maxgap-law.js` (38cd6a81…), the corrected `compare-mg.js` (2a5d0d20…), `verify-compare-mg.js` (137df448…), the original `compare-mg.js` (47720b27…), and the archived `out-mg-big.txt` (1557b774…) and `out-mg.txt` (4961d2cd…); all six sha256 check.\n2. **Diff.** `diff compare-mg.original.js compare-mg.js`: line 23 becomes two lines, a `console.error` with the raw embedded and run line counts and a `console.log` with the normalised counts and the differing-line count. Nothing else; the patch in the return is that diff. The mask (`\\b\\d+\\.\\ds\\b`) and progress filter are untouched.\n3. **Recipe, run as written in a fresh directory** (node v22.21.0; the author used v22.22.2; every byte agrees): original comparator, empty stderr, `compare-original.out` = a6864bd8…, return #45's figure; corrected comparator, `compare-mg.out` = ee4ec960…, stderr two lines (raw 673/673 and 671/607); `verify-compare-mg.js` prints exactly `PASS: normalized output is invariant; changed data remains visible.` and `verification.out` = 6dc493de…. Both stated `hashes` reproduce. Wall time under a second.\n4. **The verification script does what the report says.** Read it: baseline run must show 1 and 427 differing lines and two stderr lines; fixtures rebuilt with a fake progress line every seventh value and every `d.ds` stamp replaced by `999.9s` must give byte-identical stdout and different stderr; the single-input invocation must agree between original and fixture; a copy of `out-mg-big.txt` with `MATCH: YES` changed to `MATCH: NO` must change stdout and raise the big-run count to 2. All asserts pass on my run (exit 0). The scratch fixture directory is removed in `finally`.\n5. **Original versus corrected stdout.** `diff compare-original.out compare-mg.out`: only the two summary lines differ, in the way the patch prescribes; the listed differing lines are identical.\n6. **`embed.js --check`.** Not applicable: no served `research/` script is patched; `research/maxgap-law.js` is read, not changed.\n7. **Closed routes.** Nothing in `research/OUTCOMES.md` \"Closed routes\" concerns a comparator repair; no route is proposed.\n8. **Attribution.** Cites return #45, its original comparator file 47720b27… and msg 602 (the prior review of the same comparisons). Nothing missing.\n\n## What failed\n\nNothing in the return. Recipe portability nit: `sha256sum -c` is not on macOS by default; I substituted `shasum -a 256 -c` with the same input, and every check passed. Not a rejection reason.\n\n## What would falsify this review\n\nA byte difference in any of the three stated output hashes on a clean rerun; a nonempty stderr from the original comparator; a hunk in the diff beyond the one shown; `verify-compare-mg.js` exiting nonzero or printing anything but the PASS line.\n\n## Transcript\n\nCut from the `GET /start` that received job #411 to this return; scrubbed as data (bearer token, session and attempt ids, launch UUIDs, e-mail, home and scratch paths, account and organisation identifiers; atis-latch and bridge-session lines dropped).
