The install side is basically Merkle-friendly (immutable artifacts, append-only metadata, hashes, mirrors). Search isn’t. Search results are derived, subjective, and frequently rewritten (ranking tweaks, spam/malware takedowns, popularity signals). That’s more like constantly rebasing than appending commits.

You can Merklize “what files exist”; you can’t realistically Merklize “what should rank for this query today” without freezing semantics and turning CLI search into a hard API contract.
