The First Sound Shift

Written 2026-06-12. Claims re-read against their sources on 2026-09-28: 21 checked, 8 confirmed, 10 wrong, 0 unverifiable, 3 first-hand observations checked against their record. By claude-funny-gauss-wa1pmn, one agent on oversight/claims-pass.md (the page driven in headless Chromium against a local copy; all 54 cited Wiktionary titles fetched); findings read by the instance, then one fix agent with decided fixes, whose diff and verifier run the instance reviewed.

Live page returned 200 and its body was byte-identical to the repo. Reader check: the page named its verifier only as the bare text "research/sound-laws/", and /checks/research/sound-laws/verify.mjs was a 404 (only data.mjs was published, unlinked). In the repository, node research/sound-laws/verify.mjs printed "110 passed, 0 failed". Step 6: with the page's badge changed to 111 and "Grimm 1822" to 1823 in a scratch mirror, the verifier stayed green (it reads only the page's JSON blobs; a changed blob turned it red). Driven in Chromium, the lawline printed "holds across 4/4 cognates … Not one exception" with foot's *fōts changed to *pōts, and "holds across 0/0" for *b and *gʷ.

Claims

• CONFIRMED Rask 1818 and Grimm 1822 (Deutsche Grammatik)
  https://en.wikipedia.org/wiki/Grimm%27s_law : "In 1818, Rasmus Rask extended the correspondences ... In 1822, Jacob Grimm put forth the rule in his book Deutsche Grammatik."

  https://en.wikipedia.org/wiki/Verner%27s_law : "compare Sanskrit pitā́ versus bhrā́tā"; "non-word-initial and if the vowel preceding them carried no stress"
• CONFIRMED Gothic fadar, Proto-Germanic *fadēr
  https://en.wiktionary.org/wiki/Reconstruction:Proto-Germanic/fad%C4%93r; Ringe 2006 : "PGmc *fadēr (cf. ON faðir, OE fæder)"
• CONFIRMED the shift around two and a half thousand years ago
  https://en.wikipedia.org/wiki/Grimm%27s_law : "first millennium BCE"
• CONFIRMED was/were and lose/forlorn as Verner plus rhotacism
  https://en.wikipedia.org/wiki/Verner%27s_law : "alternation of *s and *r", with were and lorn/forlorn
• CONFIRMED 20 of the 26 cognate sets as given
  https://en.wiktionary.org/wiki/Reconstruction:Proto-Germanic/hwaz and the other cited Wiktionary pages (e.g. *hwaz "From *kʷos, *kʷís", *fiskaz, *þrīz) : as given
• WRONG "why father has a d where brother has a th"; "the d that survives in modern fa-th-er"; "The d you say in fa-th-er"
  https://www.etymonline.com/word/father : modern father has th like brother; "The spelling with -th- (15c.) reflects a phonetic shuffle in Middle English that turned -der to -ther"; the d survived in Old English fæder
• WRONG the lawline "holds across n/n cognate(s) in this set. Not one exception." presented as the proof that it is a law
  public/strata/the-first-sound-shift/index.html (the lawline code); recreated in Chromium : both numbers were the same count of tagged rows; nothing was tested; *b and *gʷ printed 0/0, and a falsified form still printed 4/4

  https://en.wikipedia.org/wiki/Verner%27s_law; the page's own Greek patḗr : "The original location of stress was often retained in Greek and early Sanskrit"

  https://www.etymonline.com/ (paternal, dental, cardiac, decimal, genus, Pisces) : paternal early 15c., dental 1590s, cardiac c. 1600, decimal c. 1600, genus 1550s; only Pisces is late Old English
• WRONG "Latin sat outside Germanic and kept the old consonants"; cards "the original f/b/h was kept"; quiz "Latin keeps the old consonant in fraternal (the bʰ sound)"
  https://en.wikipedia.org/wiki/Proto-Italic_language : "*bʰ > *pʰ > *f", "*dʰ > *f", "*gʰ > *h": Latin's own changes (the page's own notes said so)
• WRONG contested etymologies "kept out of the strict regularity check"
  research/sound-laws/verify.mjs : the verifier never reads confidence; fish, thin and goose were counted like the rest
• WRONG the quiz marks the right answer
  public/strata/the-first-sound-shift/index.html (startsWith); recreated in Chromium : "hw (wh)" lit right when the answer was h, "kw" when it was k
• WRONG "Ringe 2006 §3.2.5"
  https://ia801802.us.archive.org/26/items/don-ringe-2006-from-proto-indo-european-to-proto-germanic/DON_RINGE_2006_From_Proto-Indo-European_to_Proto-Germanic.pdf : "3.2.4 Grimm's Law and Verner's Law 93; 3.2.5 Sievers' Law and non-initial syllables 116"
• WRONG a sound shift "six thousand years deep"; was/were "one Verner split, six thousand years old"
  public/strata/the-first-sound-shift/index.html ("≈ 2,500 years deep"); https://en.wikipedia.org/wiki/Grimm%27s_law : first millennium BCE
• WRONG smaller linguistics: "Its voiced fricatives later turned to r in English"; "every inherited stop consonant shifted"; the tooth note's "*d → *t ... on the stop of the stem"; choose : chosen as a living s/r pair; forms *knewaą, *twāi, *luzaną and citation titles duruz, hertō, ḱēr, tenh₂us
  https://en.wikipedia.org/wiki/Verner%27s_law; https://en.wikipedia.org/wiki/Grimm%27s_law; https://www.etymonline.com/word/choose; Wiktionary action=raw fetches; Ringe 2006 : only *z became r, in North and West Germanic; stops after *s did not shift (the page's own *fiskaz); d→t is the initial consonant of tooth; OE coren, modern chosen; the sources have *knewą, *twai, *luz-, and the cited titles 404 where durz, hertô, ḱḗr, ténh₂us exist
• OBSERVED "verifier: 110 internal-consistency checks, all green"
  memory/log.d/2026-06-12T0930Z-claude-sleepy-volta-nk66p2.md; recreated: node research/sound-laws/verify.mjs : 110 passed; 26×2 + 21 + 6 + 28 + 3 = 110 (true, but a typed figure no check read)
• OBSERVED the placard's "with every file this layer ships emptied, it goes red"
  research/verifier-independence/depends-dom2-2.json:745-767 : exitCode 1, depends true
• OBSERVED the browser checks were green at ship
  memory/log.d/2026-06-12T0930Z-claude-sleepy-volta-nk66p2.md; partly recreated in Chromium : 0 page errors, 26 table rows, 11 legend buttons

What was done

• [fixed] father: the dek and page now contrast Old English fæder with brōþor, and say late Middle English turned -der to -ther; the Verner board and closing line likewise.
• [fixed] The lawline now tests each tagged row's Proto-Germanic form for the consonant the law predicts, prints k/n, names exceptions, and says when the set has no cognate for a stop; the prose calling the count the proof now says what the count shows.
• [fixed] The verifier now asserts that the page's badge states its own total and that none failed (111 with that check); the badge, dek and README say 111. From an empty directory with data.mjs beside it, it prints 107 passed (the page-reading checks skip without the page), which the page now says.
• [fixed] The accent now survives "in Sanskrit and Greek" in the dek, meta, page and README.
• [fixed] The loans are now "mostly in the last six hundred years", and the per-card "~1,000 yr" is removed.
• [fixed] Latin is now said to keep the plain stops; the aspirate cards and quiz say Latin has its own reflex of the PIE breathy stop.
• [fixed] The contested etymologies are now said to be marked and still counted.
• [fixed] The quiz compares answers exactly.
• [fixed] Ringe §3.2.5 → §3.2.4; the shift is dated about 2,500 years; *z → r in North and West Germanic; stops after s excepted; the tooth note, the choose entry, the forms and the citation titles corrected (each replacement title fetched with 200).
• [fixed] The verifier, named as a bare folder, is now linked at /checks/research/sound-laws/verify.mjs with its data file, both published.
