sampleWidths used floor(L/6)+1 stations from t=0, so tapered tips
dominated min/max. Sample only interior stations at 6, 12, … ≤ L−6.
When L≤12 there is no interior span: every6In stays empty and
min/max/avg stay 0. CAPTURE.md Widths bullet matches.
sqft, bdft, scale, and inventory PNG are unchanged.
Ty UAT: width min/max must describe bulk, not tips. Pin L=48 tapered
case (7 interior stations, no tip endpoints), uniform mid-board count,
and L≤12 empty/zero fallback before the sampleWidths change lands.
Length axis keeps the approved mask, replaces Flip 180 with a ± angle
slider, and sets scale from wood span along the approved direction rather
than bbox.longSidePx. Widths still sample every 6 in perpendicular to that
axis.
Why
Phone and PC need a single capture flow that ends at inventory PNG and
board-foot numbers with no backend, inference, or Woo create.
Scope
Add frontend/ Vite+Svelte capture UI with Resume, Add photo, Mask,
Length axis, and Measure. Mask runs in a worker with Auto/Green/Black
and a 2.0s sensitivity debounce. Measure computes scale, widths, sqft,
bdft, and a 3:4 alpha inventory PNG. Persist one device draft in
IndexedDB. Serve the static build from frontend/Dockerfile via nginx
(deploy/nginx-m1.conf). No FastAPI.
Verification
sudo docker build -f frontend/Dockerfile -t slabuploader-m1 .
sudo docker run -d --name slabuploader-m1 -p 0.0.0.0:18080:80 slabuploader-m1
curl http://127.0.0.1:18080/ returns 200
Playwright: synthetic green-sheet photo through Calculate shows sqft/bdft
