Cache
A server-side TypeScript cache for applications that need explicit invalidation, classified stale-on-error resilience, privacy-aware sharing, and portable runtime adapters.
Uncertain invalidation knowledge never becomes false freshness.
Cache may perform extra origin work while distributed state reconverges.
Identity is part of storage safety.
Principal-derived values stay local unless the application declares a shareable scope.
Portability is a capability boundary.
The raw constructor requires storage, a clock, and a random source from the runtime.
