Crate gatekeep_keepsake 

Keepsake-backed fact resolution for gatekeep.

The adapter maps gatekeep FactIds to keepsake relation ids. Full decisions resolve those facts from the principal’s active keepsakes. Query resolution can either do the same request-scoped lookup or mark selected facts as Unknown so a later QueryLowering adapter can turn them into row predicates.
