Struct FileHunks 

pub struct FileHunks {
    pub path: PathBuf,
    pub text: String,
    pub ranges: Vec<(u32, u32)>,
    pub changed: DiffSignMap,
    pub removed: Vec<(u32, Vec<String>)>,
}

One changed file, read and diffed: the working-tree text plus the post-image ranges its hunks occupy.

The two halves of building a batch are split around this type on purpose. Producing it is filesystem + CPU work (read_and_diff, spawn_blocking-only); consuming it spawns document actors and touches the view (attach_batch, async side). Fusing them — the PD.1 shape, where one function read, diffed and spawned — would have put every read_to_string and every diff on the actor thread the moment a trigger existed to call it.

Fields

path: PathBuf

text: String

The working-tree text, as read during the scan.

ranges: Vec<(u32, u32)>

Post-image excerpt ranges, one per hunk, context already applied.

changed: DiffSignMap

PD.7a: which post-image lines the diff touched, in source line coordinates, sorted.

Only Add and Change appear. A removed line has no post-image row to paint — showing it needs a virtual row, which is PD.7b. Recording nothing for it here is why this view currently reads as “some lines are highlighted” rather than “these lines went away”.

removed: Vec<(u32, Vec<String>)>

PD.7b: lines the diff removed, keyed by the post-image line they sat above and carrying the removed text.

These have no row in the working-tree file — that is what “removed” means — so they cannot be painted like changed. They render as virtual rows anchored above the post-image line, which is also why they are unselectable and untypeable: a line that is not in the file is not a line you can edit, and the ghost row makes that visible rather than surprising.
