Enum FileHashLookup 

pub enum FileHashLookup {
    Hit(String),
    NeedsHash(FileFingerprint),
    Uncacheable,
}

Result of a content-hash cache lookup that does NOT compute a blake3 — the lock-narrowing seam for the daemon’s HashFiles path (#281). The caller hashes (hash_file) outside any store lock on a miss, then records via FileHashCache::record_cached.

Variants

Hit(String)

Cached hash found — no hashing needed.

NeedsHash(FileFingerprint)

Cache miss; hash the file then record under this fingerprint.

Uncacheable

Too small to persist, or metadata unreadable — hash but don’t cache.
