Gap #11 ruled into 02 ▸ One-way flow: between a write's bracket and its echo the snapshot describes the past, so a guard deciding whether a write would change disk baselines on the snapshot as amended by this store's own in-flight writes — a pending-value record of the write path's own, never the EchoLedger. Relative gestures (step one width unit) resolve their base against the same amended truth, and the undo step's recorded prior reads it too. The amendment dies with its echo; failed writes never enter it. Coalescing weighed and set aside — one gesture, one write, one commit. Implementation filed on the Implementation board.

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.
