The banner surface as one vocabulary (Kanban/LiveStore/BannerCenter, Kanban/UI/BannerStripView): a pure precedence rule — in-progress pinned above the collapse (ratified mid-build), lock > breakage > one-shot write failures > commit+attachment, signposts last — with all user-facing phrasing owned here via exhaustive switches over the closed WriteOperation enum; free-form English survives only in diagnostics. performWrite posts its failures before rethrowing, so no one-shot can bypass the strip; refusals under lock post nothing. The lock vocabulary completes: vanishedRoot and unwritableLocation join bracketedReloadFailed, each with its own clearing rule (unwritable clears only on a reconciling reload's writability re-probe). The registry now owns root recovery: bookmark re-resolution absorbs renames transparently, a dead root locks read-only and re-arms FSEvents on the gone path so the root's return round-trips back through rootChanged, re-minting and re-keying on the way. DirtyBufferGuard is the one modal moment, retry / save a copy / discard, no fourth button. 36 new tests; full suite 333 tests in 62 suites green. Five findings filed on the Redesign board.

Lanework
A native macOS kanban app whose boards are plain folders and Markdown files. Every board, lane, and card is a folder with an index.md (YAML frontmatter + Markdown body); the filesystem is the source of truth and the app is a live view over it.
The defining consequence: anything that can read and write files is a first-class user of a board — text editors, Finder, shell scripts, git, and above all AI agents. Lanework's job is to be the best human surface over that substrate.
Key features
Lanework is in early development. This list tracks what has actually shipped and grows milestone by milestone; the full design lives in DESIGN/.
No UI yet — the storage foundation is in place:
- Storage contract, read side — frontmatter engine with a byte-perfect round-trip guarantee (unknown keys, comments, and formatting survive every rewrite; duplicate keys read last-wins; wrong-type scalars coerce read-side), gapped fractional ordering (Ranks), and a fail-fast board loader with UUID-gated level detection, warning-collecting skips, and tombstone-aware snapshots — pinned by a golden fixture suite of 18 on-disk boards.
- Storage contract, write side — BoardWriter turns every mutation into an atomic temp-file+rename over exactly the files it touches: creates mint lowercase-UUIDv4 identities and
.kanbanpackages; moves keep the UUID (with per-folder collision repair at the cross-board import boundary); copies mint fresh identities at every level; deletes are in-place tombstones with position-perfect restore and physical purge; attachment imports never overwrite and never refuse (Finder-style renames). Every app write stampsmodified, clearsmodified-by, and preserves everything it didn't change byte-for-byte; readable-but-uneditable frontmatter shapes refuse loudly instead of corrupting.
Development
The Xcode project is generated — project.yml is the source of truth, not the .xcodeproj:
xcodegen generate
xcodebuild build -project Kanban.xcodeproj -scheme Kanban -destination 'platform=macOS'
xcodebuild test -project Kanban.xcodeproj -scheme Kanban -destination 'platform=macOS,arch=arm64'
macOS 26+, Swift 6 (strict concurrency), SwiftUI, sandboxed. Internal codename Kanban (target, scheme, bundle id dev.rzen.indie.Kanban); the app ships under the display name Lanework.
