Per organized-ideas.md §8: the storage layer (DiagramRepository etc.) was
already renamed in an earlier phase; this finishes it everywhere else.
- domain/types.ts: Project -> Diagram. domain/project.ts -> domain/diagram.ts
(createEmptyProject -> createEmptyDiagram, default name "Untitled Diagram").
- domain/compatibility.ts, domain/bom.ts: Project param/type -> Diagram.
- data/exportImport.ts: ProjectImportError -> DiagramImportError,
projectToJson/downloadProjectFile/readProjectFile/normalizeProject -> their
Diagram equivalents.
- state/projectStore.ts -> state/diagramStore.ts: useProjectStore ->
useDiagramStore, the `project` field -> `diagram`, newProject/renameProject/
importProject/applyRestoredProject -> *Diagram, restoredProjectUpdatedAt ->
restoredDiagramUpdatedAt.
- Every component updated to match, compiler-guided (tsc -b enumerated each
remaining call site after the core rename, the same approach used for the
earlier catalog-parameter refactor).
- README updated for the terminology, and to match the repository class
names (which had already been renamed but the README hadn't caught up).
No backend/schema changes: the JSON shape stored in diagrams.data never
changed, only TypeScript-side identifiers, so existing diagrams are
unaffected. One SQL comment fixed for accuracy (no migration needed).
Verified: tsc -b and oxlint clean; grepped src/ for any remaining
Project/project reference (none) after the sweep.
- DiagramRepository interface redesigned around multiple diagrams:
list()/loadById()/deleteById() replace the old single-diagram
load()/clear(). Both implementations updated to match.
- SupabaseDiagramRepository.save() now does an explicit update-or-insert
instead of a blind upsert, so owner_id is only ever set at creation --
an upsert would resend it on every save and let whoever saves last
silently reassign ownership. Not reachable yet (no collaborator UI),
but a real landmine once diagram sharing (organized-ideas.md §8) lands,
and cheap to avoid now.
- LocalStorageDiagramRepository now stores diagrams keyed by id (was a
single fixed key), keeping it a genuine working fallback rather than
a stale reference implementing an old interface.
- Store: loadInitialDiagram (renamed from loadFromStorage) opens the
last diagram you had open (tracked in localStorage -- a UI
preference, not app data), falling back to the most recently updated
one, falling back to a fresh empty diagram. New actions:
refreshDiagramList, switchToDiagram, deleteDiagram. newProject and
importProject now persist immediately (not just via the debounced
autosave) so a new/imported diagram shows up in the list right away;
importProject also assigns a fresh id so it can't collide with an
existing diagram.
- New DiagramManagerModal (list/open/delete/+New), opened from a
"Diagrams" button in TopBar that replaces the old single-diagram
"New" button and its now-unnecessary confirmation dialog -- nothing
is lost by creating a new diagram anymore, since the old one stays
saved and reachable from the list.
Verified insert/list/update(-preserves-owner)/loadById/delete against
the real local stack; RLS test suite still 23/23 after a fresh reset.
