  "description": "MessageHeader des notifications d'événements de verrou émises par SGRDV vers un système source via $process-message. SGRDV agit comme autorité du verrou : les ajouts, prolongations et retraits sont propagés aux DMÉ par ce canal ; le DMÉ n'expose pas d'opération $lock transactionnelle. eventCoding identifie l'événement (lock-create, lock-extend, lock-release). source.endpoint identifie SGRDV de manière fixe. destination.endpoint identifie le DMÉ/SIP-C destinataire (URL technique, variable). focus pointe en logical reference vers l'Appointment (1..1) et le ou les Slots (1..*) concernés — les ressources cibles ne sont pas matérialisées dans le Bundle, le DMÉ est l'autorité d'origine de ces ressources. L'extension lock-end-time porte l'heure de fin du verrou. id sert de corrélation FHIR-natif (en complément de l'en-tête HTTP X-Correlation-Id). Le moment de l'événement est porté par Bundle.timestamp (FHIR R4 ne définit pas de MessageHeader.timestamp).",
