## Why Frequently used; top in perf profile ## Changes Most of the time, you already have the claim object in the current context. `selectClaimIsMineForUri` will retrieve the claim again, which is wasteful, even if it is memoized (looking up the cache still takes time). Break apart the logic and added the alternative `selectClaimIsMine` for faster lookup.
