Ladder Summary

file The file defines a **React Ink** component **`LaneDetail`** (exported) that shows the asks for a single lane (or a pseudo‑lane of all unclaimed asks), lets the user filter them by status, navigate with a cursor, view a full‑detail view, claim an ask, or compose a new ask. Helper utilities that are **not exported** are: * `describePayload(payload)` – extracts a single‑line description from a payload object. * `statusLabel(entry, answers, unclaimedMode)` – returns the current status string for a claimable entry. * `cycle(values, current)` – returns the next value in a circular list.

// One Lane's own asks and their status -- what LaneList's "enter"

// pushes into (zz top's lanes tab, zz work --assist's lane picker):

// see what's already queued/answered, post a new one ("n"), or (in

// --assist only, via onViewAsk/onClaimAsk) view one's full detail

// (enter) or claim it and start a work session right from the list

// ("c") -- zz top passes neither callback, since it's a pure watcher

// with no work session to start; cursor navigation stays harmlessly

// inert there.
