Lateral card navigation was pure geometry: the nearest drawn frame in the direction. That loses the walk in the card's own title — stepping from a 10-card lane's 8th card into a 3-card lane clamps to its 3rd, and coming back out, "the nearest frame at that height" is the 3rd card's height. The information the user was walking at stopped being on screen, so no rule over rectangles could have recovered it. So it is remembered instead. `TransientBoardState.lateralOrdinal` holds the 1-based position a run of ←/→ started from, counted over the cards the board is showing, and `NavigationMath.lateralHop` lands each hop on `min(ordinal, target lane's count)` of the next lane that is showing cards — collapsed and query-emptied lanes hopped over on `firstCard`'s rule rather than by the accident of registering no frames. 8th → 3rd → 8th. Every reset comes from one funnel and needs no enumeration anywhere: the ordinal is a defaulted `nil` parameter on `select`, so a click, a marquee, a ↑/↓ step, an ⌥-jump, a ⌫ successor, a lane-domain arrow and the reload's focus recovery all end the run by saying nothing. `resolve` adds the one rule a value referencing no item can need — the ordinal never outlives the head it was counted from — while a reload that leaves the cursor standing leaves the run standing too. A wide lane's interior masonry columns keep their spatial step and carry the ordinal through untouched: a column hop is not a lane hop, and stickiness is lane-granular over the logical order. With no lane in the direction the geometry has the last word, which is how → still reaches the shown trash. Claude-Session: https://claude.ai/code/session_014PtZdPwqZuqEDLc6wZMtEy
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), styling controls (03-board-ui.md ▸ Styling ▸ Controls), and comments (01 ▸ Enhanced schema + 05 ▸ The comments column — designed 2026-07-29, shipping post-2.0) each had their focused pass and are settled.
The authoritative list of open design passes is the findings board (Lanework Redesign.kanban ▸ Issues to Resolve) — this section stopped enumerating by hand after drifting twice. Standing examples as of 2026-07-29: the attachment-undo staging design and the EchoLedger foreign-undo bridge (both flagged in 13-native-undo.md), Teams' tracker integration (no design yet), the fail-fast decision surface (01 ▸ Refuse), and the drop-release settle presentation (03 ▸ Motion — deliberately last in line).
Wishlist
Ideas worth keeping but outside the committed design live in ../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.
