After bootstrap, open a clientv3 Watch from the bootstrap watermark+1 over the whole keyspace and apply every event (PUT/DELETE) into the etcd_* spaces, advancing the local synced watermark per event header. Must handle: - Progress notifications (WithProgressNotify) to advance the watermark even when idle, and detect staleness. - ErrCompacted (code 11): upstream compacted past our position -> trigger a re-bootstrap (tarantool-etcd child) then resume. - Reconnect/backoff on upstream Unavailable; resume from last applied revision. - Ordering: apply events in revision order; the local revision counter tracks upstream mod_revision (see revision-alignment child). This is the steady-state engine of mirror mode.
ErrCompacted=11 and progress-notify semantics are the ones we already understand from conformance work (see clientv3 quirks memory).
