+jeton est stockee, jamais le jeton lui-meme, pour la meme raison (revocation en cascade,
+aucune session utilisable dans un pg_dump qui fuiterait).
+
+`password_reset_attempt` vit hors de `audit_log`, comme `login_attempt`, car son volume est
+pilote par l'attaquant : une campagne de demandes y ecrirait des lignes que l'audit, en ajout
+seul, ne devrait jamais purger.

+Toutes les routes sont préfixées par `/api/v1`.
+
+**Authentification.** Le jeton d'accès se présente dans l'en-tête `Authorization: Bearer ...`.
+Le jeton de rafraîchissement est un cookie `HttpOnly` que le code client ne voit jamais : il
+suffit d'émettre les requêtes avec les identifiants de session. `POST /auth/refresh` rend un
+nouveau jeton d'accès et fait tourner le cookie.
+
+**Rôles.** `lecteur`, puis `operateur`, puis `admin`. Chaque rôle couvre les droits du
+précédent.
+
+**Erreurs.** Le corps porte toujours une clé `detail`. Un `403` dont le `detail` vaut
+`password_change_required` n'est pas un refus de droits : il exige le changement du mot de passe
+provisoire avant toute autre action.
+
+Le parcours de session complet est décrit dans
+`docs/architecture/31-contrat-authentification.md`.
