Kai — the one true spelling, and the forms that fail it
The internet spells Kai more ways than one, and only one of them is the name the sources wrote. This is the register's ruling — canonical, fallback, contested, and false, each in its proper place.

The Canonical Form
The tradition's record preserves this name in its romanized scholarly form: Kai — no older script survives to transcribe, so the canonical content is the exactness of the spelling itself.
No diacritics are required here: the canonical form is the exactness of the spelling itself, the form the tradition’s convention demands.
Where the Flattened Form Stands
The plain form kai differs from the canonical Kai only by convention of display — case, not content. It is acceptable everywhere: in legacy systems, in plain-text citation, in the DNS itself. What is not acceptable is what follows in the register: respellings that change the letters, not just their case.
The Register of False Forms
No circulating form of this name currently qualifies as false under the register's standard — a rare standing. The spelling is short, sturdy, and rarely mangled.
The Contested Forms
No alternate form of this name carries documented scholarly support in the lexicon's record. The convention here — the tradition’s standard — produces exactly one defensible transliteration: Kai. Forms that differ from it are not contested; they are simply wrong.
The Convention's Own History
Every tradition in this register has its own scholarly transliteration standard, built by its own specialists over decades or centuries, and the register follows each on its own terms: the tradition’s own standard. The principle that unifies them is the one the whole project stands on: a name is evidence, and evidence is not negotiable — not for keyboards, not for convenience, not for anyone.
What the Address Bar Allows
IDNA 2008 permits the letters these restorations use — macrons, acutes, underdots, thorn, ogonek, the lot — and the DNS carries them as punycode (`xn--` labels). Two honest constraints remain. First, registrar inventory: the protocol permits a character; the registrar's stock decides whether the exact domain can be bought today. Second, combined marks: forms like Apṓllōn (acute stacked on a macron) are philologically ideal yet effectively untypeable on phones and unsupported across much of the registration system.
That is why the rulebook keeps a fallback hierarchy — full restoration first, then the circumflex when the source carries one, then the macron-only academic standard, then an attested variant, and only as a last resort the plain ASCII form. Every step down the ladder is still defensible; nothing on the ladder is a wrong mark. A fallback is a choice among attested forms. A false form is not on the ladder at all.
Where the Name Stood First
Kai is a literary figure: no inscription, ogham stone, or Romano-British dedication names him, and Welsh tradition generally left texts rather than cult monuments for its heroes. His manuscript witnesses are exact and early. The dialogue poem Pa Gur survives in the Black Book of Carmarthen (c. 1250), the oldest substantial manuscript of Welsh verse; Culhwch ac Olwen survives in a fragmentary copy in the White Book of Rhydderch (Peniarth 4–5, c. 1350) and complete in the Red Book of Hergest (Jesus College MS 111, c. 1375–1425); and the Otherworld-raid poem Preiddeu Annwn, the companion witness to this stratum, is preserved in the Book of Taliesin (Peniarth 2, early 14th c.). Geoffrey of Monmouth's Historia Regum Britanniae (c. 1136) and Lifris of Llancarfan's Vita Cadoci (c. 1100) carry the Latin attestations. The places of the tales — Caer Loyw on the Severn, the Anglesey of Cath Palug — remain on the map, but the tall man himself left nothing in stone. The temple on the web is the newest of these addresses — the first one that fits in a pocket.
The Verdict
The register rules for Kai, and the ruling is checkable: every mark sourced, every violation stated, every borderline form given its honest standing. kai carries the name freely — it differs only in display, and the register says so without reservation. Anything else in circulation has its origin and its failure recorded above. That is the whole of the law on this name — and the temple at /sites/kai/ enforces it.
The docket for this ruling: no false forms on the docket; no contested forms attested; the attestation rests on 9 cited sources — Culhwch ac Olwen (Mabinogion), trans. Gwyn Jones and Thomas Jones — the first companion; the attribute list; Wrnach; Dillus; the englyn and the rift; Cei's death avenged, Pa Gur yv y Porthaur? (Black Book of Carmarthen) — the nine witches; Cath Palug on Anglesey, Trioedd Ynys Prydein, ed. and trans. Rachel Bromwich — the three powerful swineherds; the birth of Cath Palug from Henwen.
The Register Continues
This is one of 397 entries in the Canonical Register — the authoritative reference for every flagship temple. The temple's founding dispatch tells the name's story; its Restoration File details the marks; its Resonance File reads the archetype into the industries. The blog index holds the whole archive, and the Rulebook states the convention this register enforces.

The Canonical Register is written from the same canonical record as the lexicon itself. If a false form is missing from this page, it is because the evidence does not support calling it false — or because we have not seen it yet. Show us, with a citation, and the register will answer.
