Struct Snapshot 

pub struct Snapshot {
    pub path: String,
    pub text: String,
    pub hash: String,
    pub recorded_at: SystemTime,
    pub seen_lines: Option<HashSet<u32>>,
}

One full-file version observed at a point in time. The tag the model sees is Snapshot::hash; recovery replays edits against Snapshot::text.

Fields

path: String

Canonical path this version belongs to.

text: String

Full normalized (LF, no BOM) file text as observed.

hash: String

Content-derived tag for Snapshot::text (see compute_file_hash).

recorded_at: SystemTime

Wall-clock time the version was recorded.

seen_lines: Option<HashSet<u32>>

1-indexed file lines a producer actually displayed under this tag. A partial read leaves this sparse; a whole-file read fills every line. Multiple reads of the same content union into one set. None means “no provenance recorded” — the patcher then skips the seen-line check.
