Where MorrowCache wins
Paraphrases can HIT via intent adjudication instead of missing every time. Morrow still keeps an exact path for identical bytes, same-intent sits on top, fail-open if the judge fails.

Exact bytes
vs exact-only cache
Cache only when the request bytes match. Safe, narrow, and blind to “please explain mutexes.”

X-Jevcache: MISSWhere they win
Exact-only has a simpler threat model: no adjudicator, fewer ways to be wrong. If traffic is already normalized to identical prompts, exact is enough and cheaper to reason about.
Verdict
Identical prompts: exact is enough. Rephrased prompts: Morrow adds same-intent hits.
