## Other responses

- `400`: Requête invalide (champ manquant, borne dépassée, curseur illisible).
- `404`: Ressource introuvable.
- `429`: Cadence dépassée (code « rate_limited »). La réponse porte X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Window et Retry-After — attends la fenêtre indiquée : un retry immédiat la prolonge. Les plafonds appliqués sont dans x-kaneme-rate-limits. Quand le refus vient d’un plafond PAR OPÉRATION (générer, créer un document ou un projet, déposer une source), ces nombres sont ceux de CETTE opération, pas ceux de la surface.
- `500`: Erreur interne.
