Separate read-only canvas for physically laying out wire harnesses.
Syncs connectors from the main diagram (one-way), no changes flow back.
Backend:
- FormboardLayout, FormboardNode, FormboardSegment models
- /api/formboard/ router: get/create layout, sync connectors from diagram,
full CRUD for nodes and segments
Frontend (formboard.js):
- Konva canvas: drag nodes, click-to-connect segments, zoom/pan
- Node types: Connector (blue rect, synced from diagram), Branch (green
circle, manual), Splice/joint (orange diamond, manual)
- Segments scale thickness by wire count; fitting overlays for open,
split loom, conduit, heat shrink, tape wrap
- Right-click context menu for delete on nodes/segments
App integration:
- "⊞ Formboard" tab in view-tab-bar (distinct color, independent of views)
- Sub-toolbar: Select / Branch / Splice / Connect / Sync / Fit / Delete
- Right panel swaps to formboard props when active:
- Node: label, notes, linked device info
- Segment: fitting type, fitting color, label, length, wire checklist
(checkboxes for every wire in the main diagram)
