⌘P had no story: KanbanApp removed the platform's Print row outright on 11-command-nexus.md's "No Print story in v1 (⌘P unused)" line. That line retires. File ▸ Print… now prints the board in front — lanes left to right, each lane's cards top to bottom, as a linear document rather than a picture of the strip — or, from a card window, that card. The trash is unreachable by construction: it is a sibling container of `lanes`, not a lane. The rules live in a pure layer nothing AppKit can reach. `PrintOptions` is one Codable value carrying the printing card's five bullets — which components (title, icon+labels line, rendered body, comments off by default with either reading order), page breaks, one base face and size every other size derives from, and a toggleable running head and foot. `PrintSource` is what is being printed, frozen at ⌘P so the panel's repeated relayouts and a board reloading underneath cannot disagree. `PrintDocumentBuilder` turns the pair into a block list, which is where every decision a rendered page hides becomes something a test can hold: component order, comment ordering, and page-break markers that are markers rather than whitespace. Empty is empty all the way up — a card with nothing to print consumes no page break, and a lane whose cards all dropped out takes its heading with it. A page break is a pagination fact, not a spacing one. TextKit has no page-break character, so `PrintDocumentView` splits the document into sections at its breaks and flows each into as many page-sized text containers as it needs: a container boundary *is* a sheet boundary, at any paper size with any margins. Bodies come from the app's one Markdown pass — `BodyMarkup.parse` into `BodyMarkupRenderer` — re-faced run by run so the chosen family reaches the text and fixed-pitch code keeps its own, and drawn under a forced light appearance so the card window's dynamic label colours do not print white. Options ride in the print panel's own accessory rather than a pre-flight sheet of ours, which buys the system's live preview of the real paginated document; the preview refreshes through one KVO revision counter rather than thirteen mirrored properties. Profiles persist app-side in UserDefaults, never in board files — a print profile is how this user likes to read, not what a board is (`BoardZoomStore`'s argument). A name is a profile's identity, folded case-insensitively; "Last Used" is reserved in every spelling, kept out of the stored list, and captured when an operation actually ran, so a cancelled print rewrites nothing. Both decoders are total: one unrecognized key must not cost a user every profile they saved. DESIGN/11-command-nexus.md gains the Print row and loses the sentence saying it would never have one.

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.
