18 golden fixture boards as real on-disk trees under Fixtures/ — ten valid/tolerated cases (rich board, interrupted create, non-UUID strays, stray files, tombstones, tie-breaks, unknown-key order, coercion, last-wins duplicates, board-level deleted) and eight fail-fast cases, each pinned to its exact error reason and path; the rich board's whole tree round-trips byte-identically. Pins two contract subtleties now recorded in the design: tombstone flags are not inherited (renderers walk ancestors) and last-wins resolves before order strictness. README gains the storage-foundation feature entry. 146 tests total. Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A

A hand-edit that types 'title' twice — strict YAML would reject the file outright. The engine reads the last occurrence and keeps both on disk.
