01's Lanework-owns-the-board carve-out: a regular file beside a card's index.md belongs in attachments/, and the app moves it there. The loader detects read-only — a new LoadResult.looseCardFiles channel, separate from the stray-tolerance warnings because it says the opposite thing — skipping directories, symlinks, hidden entries, and the reserved names compared case-insensitively (on APFS, Index.md IS the index). The relocation rides one performWrite bracket at the tail of every successful reload, which makes lock deferral free: the reload that lifts a read-only lock is the reload that relocates. A lane/card/filename memo keeps a failing relocation from hot-looping — one one-shot, then silence until disk changes. The notice rides the loss-row class, phrasing folded by BannerCenter (one file, one card's files, a multi-card sweep), naming original filenames per the importAttachment rule. Paste normalizes at the import boundary: staged snapshots' loose files land in the pasted card's attachments silently, every arrival path declaring its side via an explicit normalizingLooseFiles parameter — drag paths decline and fall back to the destination's own carve-out. checkIsCardFolder closes the hole where a lane's notes.txt would have been relocated: card depth is exact, UUID under UUID.

Fixture boards
Golden fixture boards for the storage-contract test suite — real on-disk folder trees, not inline strings, so the same fixtures can later drive XCUITests via the --open-board launch hook.
Bundled into the unit-test target as a folder reference (see project.yml). Valid boards live under Valid/, fail-fast cases under Malformed/. Tests live in KanbanTests/FixtureBoardTests.swift.
Hidden fixture files are named .hidden-* rather than .DS_Store: the repo's .gitignore ignores .DS_Store everywhere, so a fixture spelled that way would exist on the authoring machine and vanish from a fresh clone. The loader's rule is .skipsHiddenFiles — it is about the leading dot, not the name.
Lane/card folder names are fixed literal lowercase-UUIDv4-shaped strings (never generated at test time), chosen so their lexicographic order matches the expected tie-break order — usually a leading digit (10000000-..., 20000000-..., …) so folder order reads the same as array-index order in the tests. That is a fixture-authoring convention, not the loader's gate: the identity predicate is shape-only (8-4-4-4-12 hex, any case, any version — 01-storage-format.md § Fractal layout ▸ Rules), and the case/version coverage lives in KanbanTests/BoardLoaderTests.swift rather than here.
Valid/ — one board per tolerated/valid case
| Board | Case |
|---|---|
rich-board.kanban |
A full-breadth well-formed board: 2 lanes, 3 cards, bodies, styling (background/icon/iconColor/width), unknown + reserved frontmatter keys, attachments/ and comments/ with real content. Its attachments/ also carries all four listing shapes — two ordinary files, a hidden one, and a subfolder with a file — so Card.attachments' flat rule (01-storage-format.md § Attachments) is asserted against a real tree. Also the board every index.md in the tree is round-tripped against. |
interrupted-create.kanban |
The motivating skip-not-error case: a UUID-shaped lane folder and a UUID-shaped card folder, each with no index.md yet (folder created, write not yet landed). |
non-uuid-strays.kanban |
Non-UUID-shaped folders at both lane and card depth, with and without index.md — name shape gates candidacy before the file is ever read. |
stray-files.kanban |
Stray (non-directory) files at board, lane, and card level — never level candidates, never warned about. The card-level one (scratch.md) is also the loose-file carve-out's golden case: tolerated everywhere else, it is reported in LoadResult.looseCardFiles for the app to relocate into attachments/ (01-storage-format.md § Fractal layout ▸ Rules, settled 2026-07-28). Detection is read-only, so the file stays put on disk. |
tombstones.kanban |
A tombstoned lane and a tombstoned card, both still on disk and still in the snapshot, flagged (isDeleted) rather than removed. Also proves a tombstoned lane doesn't recursively flag its own un-deleted children. |
duplicate-order-tie-break.kanban |
Three cards sharing one order in one lane, and two lanes sharing one order — both broken by folder name, ascending. |
unknown-key-order.kanban |
Unknown/reserved frontmatter keys interleaved with schema-owned ones at board, lane, and card level — document.unknownFields must preserve exactly the order they were written in. |
coercion.kanban |
Lenient-field coercion and fallback: wrong-type scalars that coerce (title: 2048, iconColor: 42, background: 12345, width: "3") versus ones with no sensible reading that fall back to the default (title: [a, b], background: {x: 1}, width: 1.5), plus a deleted with an unusable timestamp that still tombstones. |
duplicate-top-level-keys.kanban |
A top-level key written twice — at board, lane (the strict order field), and card level. Last occurrence wins; not a fail-fast case (settled, newer than the original card text). Round-tripped to prove the earlier occurrence survives on disk, invisible only to reads. |
board-level-deleted.kanban |
A board-level deleted: key — legal per the frontmatter table but meaningless; ignored + warned, rest of the board loads normally. |
Malformed/ — one board per fail-fast case
Each board is minimal: one broken thing.
| Board | Case |
|---|---|
unparseable-yaml.kanban |
An unterminated flow sequence in the board's frontmatter. |
missing-schema.kanban |
Board root index.md has no schema key. |
schema-newer-than-app.kanban |
Board root schema: 2, newer than BoardLoader.supportedSchema. |
missing-order-lane.kanban |
A UUID-shaped lane index.md with no order key. |
missing-order-card.kanban |
A UUID-shaped card index.md with no order key. |
explicit-null-order.kanban |
A lane's order: key present with no value — reads as missing, not malformed. |
non-numeric-order.kanban |
A card's order: banana — present but not a number. |
board-root-missing-index.kanban |
The board root folder itself has no index.md. |
