- * Condition that determines if personal data fields should be hidden based on BPN mutability flag.
+ * Condition that determines if personal data fields should be hidden based on the
+ * booking-level MOEGLICHEAENDERUNGEN/teilnehmerdaten flag.
  *
- * This condition respects the BPN API's per-participant mutability flag (`aenderungmoeglich`).
- * When a participant's data is not mutable (mutable=false), personal data fields should be
- * hidden and displayed as static text.
+ * Uses Travel::participantDataMutable (defaults to true) which is populated from the
+ * MOEGLICHEAENDERUNGEN API endpoint. When BPN marks participant data as not changeable
+ * for a booking, all core personal data fields are rendered as static text.
  *
- * This condition is combined with FirstParticipantReadOnlyCondition via OR in edit mode.
- * FirstParticipantReadOnlyCondition handles agency-based read-only logic for first participant,
- * while this condition applies BPN mutability rules to all participants.
- *
- * Exception: For internal agency bookings (agency code 0004), the BPN mutability flag
- * is ignored for all participants. Agency staff need full control over participant data
- * regardless of BPN's mutability restrictions.
- *
- * In edit mode, BPN determines mutability based on business rules (e.g., payment status,
- * booking state, etc.). We must respect this flag to prevent users from attempting to
- * modify data that BPN will reject.
- *
- * When this condition is satisfied (returns true), the template renders fields as
- * static text via the `field_or_static` macro instead of form inputs.
+ * Exception: internal agency bookings always allow editing regardless of this flag.
