Struct Enumeration 

pub struct Enumeration<'a> {
    pub raw_records: &'a [u8],
    pub canonical_patch: &'a [u8],
    pub rename_records: &'a [u8],
}

The three git outputs enumeration is built from.

Bytes, not paths or a repository: which commands produced these is the adapter’s business, and the parsers were validated against real git output (ADR 0002).

Fields

raw_records: &'a [u8]

diff-tree -r -z --raw --full-index --no-renames: authoritative modes, full oids, dispositions.

canonical_patch: &'a [u8]

diff-tree -r -U0 --no-renames --no-color --no-ext-diff: the canonical patch. Every hunk in the system comes from here.

rename_records: &'a [u8]

diff-tree -r -M -z --name-status: rename-detected annotations only (ADR 0003). Never affects what exists.
