The right-edge drag's growth was capped at the screen's visible frame, because each snap tick grows the window; on a window near the screen edge that left a lane stuck at a tick or two of headroom. Settled 2026-08-08 (03-board-ui.md § Lane, superseding the pathfinder's hard stop): at the screen the window pins and each further tick re-divides the fixed strip width across one more unit — siblings compress, the stepper's mechanism arriving under the drag's fingers. The regimes meet with no pixel jump (the re-divided standard at the fit IS the frozen standard, by the exact-fill identity), shrinking mirrors the way back, the rubber band moves to the strip's own capacity, and a window with no headroom at all — full screen included — re-divides from the very first snap. New pure arithmetic in LaneLayoutMath (pinnedStripWidth, resizeStandard, resizeMaxUnits, resizeWindowDelta, snappedUnits over per-count slots); LaneResizeSession splits the tick across the regimes and derives its standard from the live count; the handle and BoardView hand the session the strip's whole divide. 2709 unit tests green (+11).

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.

| 13-native-undo.md | macOS-native undo/redo — the history substrate (sole since 2026-08-08); owns Undo routing |

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.
