Overview

A small thread-safe, TTL’d key -> value store for the short-lived grants the provider issues (authorization codes, access tokens, refresh tokens). Entries expire and are pruned lazily on access, plus an opportunistic sweep once the store grows, so even never-redeemed grants don’t accumulate without bound. The advertised lifetimes are enforced. Uses a monotonic clock (immune to wall-clock changes).
