- stores/versions-store.ts, hooks/use-session-manager.ts,
lib/session-storage.ts: remove the diagramHistory conversion layer,
the localStorage chat migration and the empty templates store
- stores/canvas-store.ts, lib/drawio/editor-bridge.ts: remove the
pages list nothing read
- components/chat/chat-engine.tsx: use the context's chartXMLRef and
latestSvgRef instead of local copies, subscribe to one settings field,
stop prefetching quota limits (lib/use-quota-manager.tsx takes the
values from the 429 body), readDiagramFile delegates to the MCP
loader (which now strips XML prologs and accepts <svg:svg>)
- contexts/diagram-context.tsx: one requestTaggedExport path for
thumbnails, validation, fetch and save; fetchDiagramXml replaces
handleExport plus the exported resolver map
- hooks/use-validate-diagram.ts and app/api/validate-diagram: plain
fetch returning JSON instead of a streamed object nobody consumed
- hooks/use-diagram-tool-handlers.ts: drop the DEBUG blocks; canvas
vars inheritance lives in placeOnPage (lib/diagram-pages.ts)
- lobby-hero, icon-button, drawio-frame: remove unreachable branches
and unused props
* fix(chat): the AI reads and draws the page the user is viewing
The model always got the first page and display_diagram replaced the whole
file with one page, so drawing on page 3 of a multi-page file deleted the
other pages (#241), and edits went to page 1 while the user looked at
another page.
Now a turn records the page the user is viewing when the message is sent.
That page's model goes to the model (also as previousXml, on regenerate and
in edit_diagram error messages), selected shapes are sent on any page,
display_diagram and append_diagram replace only that page (a drawing that
brings several pages still replaces the file), edit_diagram targets it,
and the streaming preview draws on it. Compact cells and default styles
take the layer and the edges of that page, in the preview and in
editDiagram. The editor bridge replaces the current page in place when the
other pages are unchanged, so Ctrl+Z undoes an AI change on a multi-page
file in one step; when a full load is needed, the user's page is shown
again afterwards. Version summaries and the compare dialog count the page
the change was made on.
* test: read the failed edit's output without unsafe optional chaining
