Struct Digest 

pub struct Digest {
    pub count: u64,
    pub watermark: i64,
    pub aggregate: String,
}

The durable digest of a StatMap. count is the entry count, watermark the maximum mtime, aggregate a short content hash over the sorted (path, mtime, size) tuples. Two maps produce the same digest iff they hold the same files with the same (mtime, size), so a digest change is a reliable “something moved” trigger; count/watermark shifts make additions and deletions visible even without the full map.

Fields

count: u64

Number of files in the map.

watermark: i64

Maximum mtime across the map (integer ms), 0 for an empty map.

aggregate: String

SHA-256 over the sorted (path, mtime, size) tuples, first 16 hex.
