Stated 2026-07-29: when duplicate occurrences straddle live and trashed, the live one keeps the identity regardless of age — a restore done as a copy must never see the restored card withheld in favor of its trash ghost; the silent heal remints the trashed occurrence. Uniform across content duplicates, case-twins, and trashed lanes sharing a live lane's UUID. Board: Minor card 94086f7b → Resolved. Minor lane now holds only tombstoned sweep cards.

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.
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.
