Unclear What the identities map is used for and what user-visible effect stale entries would have is not stated.

What

An internal caching component used for session storage now tracks an additional identities map. When cached entries are invalidated on the "read" path, matching keys are now also removed from this identities map, not just from the main cache.

Why

This keeps identity-related cache data from going stale alongside the rest of the invalidated cache, avoiding a case where stale identity data could linger after a read invalidation.
