Review Comment:
Fix was applied in commit 49dbed21 — callback-ref branch added so function
refs now receive the correct values. Thread resolved.

Review Comment:
Suggestion declined — the `if (oldestKey !== undefined)` guard is required
to satisfy TypeScript strict null checks. `Map.prototype.keys().next().value`
is typed as `K | undefined` because `IteratorResult.value` widens
unconditionally; the runtime invariant that the cache is non-empty is not
tracked by the type system. Thread closed.
