# Lanework — Design Documents

A ground-up rewrite of the Kanban app, to ship as **Lanework** on the Mac App Store. The old repo (`../../Kanban`, one level above this repository — not the rewrite's own `Kanban/` source folder, which shares the codename) was a pathfinder — it never shipped, but it is the reference implementation and the source of hard-won decisions. This design starts from a clean slate and keeps only what earned its place. The rewrite keeps the internal codename `Kanban` (bundle id `dev.rzen.indie.Kanban`).

Each document covers one aspect of the design. Within each:

- **Decisions** — settled, either carried over from the old app or newly made.
- **Changes from Kanban** — where this rewrite deliberately diverges.
- **Open questions** — flagged for iteration; nothing here is implicitly settled.

## Deferred design iterations

The card window (05-card-window.md), toolbar (03-board-ui.md ▸ Toolbar), and styling controls (03-board-ui.md ▸ Styling ▸ Controls) each had their focused pass and are settled. The 2026-07-27 edition split (12-editions.md) added two deferred passes: the attachment-undo staging design and the EchoLedger foreign-undo bridge (both flagged in 13-native-undo.md), plus Teams' tracker integration (no design yet).

## Wishlist

Ideas worth keeping but outside the committed design live in [../WISHLIST.md](../WISHLIST.md).

## Terminology

The rewrite adopts **lane** as the canonical term for what the old app called a column (it's in the name: Lane-work). "Column" survives only when referring to the old app or to interior card-grid columns inside a wide lane.
