Ladder Summary

file The file implements the **Explore** pane used by the “find more repos” tab of the `zz top` TUI: it renders either a **RemoteExplore** (search‑box that queries the backend, shows debounced results, loads a preview with ladder and lane info, and lets the user “track” a repo) or a **LocalExplore** (filesystem browser) depending on the `local` prop, while managing edit‑mode state so the surrounding `TabView` can suspend its own key handling. **Exported members** - `Explore` – the top‑level React component that switches between the remote and local explore modes. (All other functions and components such as `IdleLogo`, `callToolAnon`, `loadPreview`, `RemoteExplore`, etc. are internal to the file.)

// `zz top`'s "find more repos" tab -- reachable at any time via the

// normal tab navigation (see TopApp.tsx), same "track" action either

// way (top.ts's own onTrack), but a completely different interaction

// per mode: remote is a search box against the real backend; local is

// a filesystem browser, since there's no server to search against.

// Free-text search needs every character (including letters/digits

// TabView's own hotkeys use for tab-switch/quit/copy), so remote mode

// has an explicit edit-mode toggle ("/" to start typing, Enter to

// search and stop, Escape to cancel and stop) -- while editing,

// onEditingChange(true) tells TopApp to pass `inputPaused` down to

// TabView, suppressing its own key handling for exactly as long as

// typing is happening. Local mode never needs this: directory

// navigation (arrows/enter) and "t" to track don't collide with

// anything TabView listens for.
