# Firehose message which declares the current state of the repository. The message is meant to
11
+
# trigger a resynchronization of the repository from a receiving consumer, if the consumer detects
12
+
# from the message rev that it must have missed some events from that repository.
13
+
#
14
+
# The sync message can be emitted by a PDS or relay to force a repair of a broken account state,
15
+
# or e.g. when an account is created, migrated or recovered from a CAR backup.
