Module redb 

redb-backed EventStore implementation.

One redb file per run at <base>/<instance_id>/<run_id>.redb. Every commit uses [Durability::Immediate] so a crashed writer never leaves the in-flight tail visible after reopen, and the high-watermark only advances after a durable acknowledgement.
