reindex was embedded-only, so a node's index could not be rebuilt in an external-NATS deployment (the durable position and shared cursor live in NATS, outside a node's --data). --nats routes reindex through the shared plane; the reset republishes the census that every node's fold absorbs. Validated on Linux/hetzner over external NATS. check-in: 87282e7532 user: dmestas tags: trunk
