- Noms des liens d'équipe : comparés sans casse, accents ni ponctuation (ld_engine::names), lettres latines seulement (pas de sosie cyrillique, grec ou pleine chasse), une ligne ; index unique (migration additive 0003) contre deux ouvertures simultanées sous le même nom. - Une personne déjà connectée ne prend une place que si le lien lui ajoute un groupe ; « Ce n'est pas moi » la déconnecte sur un navigateur partagé ; un lien collé dans le même onglet est relu. - Coller ou couper un mot de quantité n'est pas une coquille (« sur tout » → « surtout », « par tout » → « partout »). - Libellés sans caractère de contrôle ; la soumission revérifie le titre. Boucle : 68 tests Rust, svelte-check, 9 vitest, e2e 13/13. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! Names people give themselves (team links): what is accepted, and the key two
|
||
//! names collide on.
|
||
//!
|
||
//! A name is shown as the author of proposals, revisions and signals, so nobody
|
||
//! may take a name already there, even dressed differently: « émile » for
|
||
//! « Émile », an accent written apart, a Cyrillic « в » or a Greek « Υ » for a
|
||
//! Latin letter, full-width « Ｙｖｖ ». Hence a short alphabet — Latin letters
|
||
//! as French, English and Spanish write them, figures, space, hyphen,
|
||
//! apostrophe, dot — and a key that forgets case, accents and punctuation.
