06 and 10 consumed a per-file app-vs-foreign classifier that 02's component inventory never named and whose layering prose seemed to deny. Settled: a new EchoLedger component records each BoardWriter operation's expected outcome (content hash / absence / move pair); final-content matching classifies each observed file, deciding both races (byte-identical foreign write → app-mediated, accepted; same-window foreign overwrite → foreign, last writer wins). Ledger is in-memory and per-store; launch catch-up is all-foreign; bracketed operations bypass it. "Trusts its own writes no more than anyone else's" is scoped to rendering; BoardWriter's no-hidden-state bullet stands. Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
