Ownable resources

Transfers with lineage

Every hand-off is an atomic, receipted edge. Walk the chain of custody back to origin at any time.

Policy at the edge

Relationship-based rules evaluated in single-digit milliseconds, cached close to your users.

Delegation & expiry

Time-boxed grants that revoke themselves — no cron jobs, no orphaned access.

Graph queries

Ask what a subject can touch, or who can touch a resource, in one call.

Audit-linked

Every mutation emits an audit event automatically, so ownership history and audit trail never disagree.

Wired in one afternoon
