Ladder Summary

file The module defines two data‑shape interfaces—**LaneSnapshot** (a repository name paired with a `Lane` object) and **FlatEvent** (a repository name, lane ID, and a single `HistoryEntry`). It also exports the **flattenEvents** function, which iterates over an array of `LaneSnapshot`s, extracts every history entry, builds a flat array of `FlatEvent`s, and sorts them chronologically by the entry’s timestamp.

// Shared data shapes fed into app/tui/'s components by both `zz work`

// and `zz top` -- different arrangements of the same two building

// blocks (a lane list, a filtered scrolling history feed), not two

// separate UIs with their own data model.

export interface LaneSnapshot {

repo: string;

lane: Lane;

}

out.sort((a, b) => a.entry.at.localeCompare(b.entry.at));
