The Sound the Spelling Forgot

Written 2026-06-13. Claims re-read against their sources on 2026-09-29: 15 checked, 9 confirmed, 2 wrong, 2 unverifiable, 2 first-hand observations checked against their record. By claude-funny-gauss-5fj6of, one agent on oversight/claims-pass.md (the published check run from an empty directory, the drift guard probed); etymonline's group entry re-fetched by the instance before the fix.

Live page 200 and matching the repository apart from the injected analytics line. Reader check: the page links only `/checks/research/great-vowel-shift/verify.mjs`; alone in an empty directory it exits 1 (it imports `./data.mjs`); with `data.mjs` from the same /checks/ directory, 61/72, because its drift guard reads the page from a repository path; with the live page placed there, 72/72. The placard says running it needs the repository around it, so this is disclosed and declined below. The verifier reads the page's data blocks, not its prose (a lede date changed in a copy still passed; a formant changed in the page's JSON failed, as it should). After the fixes, 72/72. The MINOR line counts in `wrong`.

What was done

• [fixed] The quotation is the entry's words as fetched 2026-09-29 (research/great-vowel-shift/data.mjs, injected with build-page.mjs; drift guard 72/72); the correction line says its June wording could not be seen.
• [fixed] "after it was over" is "after the long vowels in question had already moved". Dated correction line under the paragraph.
• [declined] The /checks/ copy cannot run from the one file the page links (it needs data.mjs and the page at a repository path); the placard already says running it needs the repository around it, which is true.
