sentinel
Sentinel is a filesystem-backed document DBMS written in Rust.
...Each document includes full audit metadata—creation timestamps, version history, hashes, and signatures—viewable with standard UNIX tools.
Designed for edge deployments, compliance systems, audit logs, certificate management, and regulatory reporting. No server required, works entirely on filesystem with Git-based replication. Zero vendor lock-in—migrate anytime using standard tools like rsync, tar, or git.
