 - [Phase 12]: 12-02: Parity cases that mutate state are recorded from a fresh PHP tinker reset (parity/fonoteka_reset.php) and replayed from a fresh fonoteka seed per case; id sequences lifted to 8 digits
 - [Phase 12]: 12-02: The backend admin album binding keeps a non-provisioning resolver; only API callers provision
 - [Phase 12]: 12-02: Winter HttpException pages are embedded as winter_<status>.html with only the app.url stylesheet origin templated
+- [Phase 12]: Invitation ValidationExceptions (store required|email, normalizeEmail) answer Winter's 500 error page, as recorded PHP does; the store runs a Laravel RFCValidation email port before normalizeEmail
+- [Phase 12]: Invitation mail is a conga Enqueue River job on the invite transaction with the token as lagoon.Encrypted ciphertext; the worker skips superseded or non-pending invitations
+- [Phase 12]: Every resolver caller maps errors through writeResolveError (404 page, 409 pending-invitation page, else opaque 500)
+- [Phase 12]: Route parity cases needing an invitation token seed it on both sides as secret:invite; flows read a PHP-minted token from the log mailer (php_parity.sh serve-mail, invite-token)
