The client is a pure API consumer: live frames go out over /v1/stream, stills
over /v1/recognize, and it can be pointed at another server with
?server=&token=. It keeps the team's visual identity (green palette, logo, EN/JA
toggle) and adds the live surface: state-coloured boxes with name/price chips,
interpolated track boxes, a results/s + latency HUD, quality hints, and an
in-view list that highlights a SKU's boxes.
Photo mode recognises the whole shelf at once instead of one click per product:
boxes paint immediately, identities fill in, tapping a product inspects it
(crop + feature-match visualization), the algorithm selector re-classifies, and
dispense updates stock.
Fixes found by browser verification with a synthetic camera feed:
- The WebSocket handler referenced its processing loop before definition, so the
socket died with NameError and live mode never received a result. Helpers are
now defined inside the handler.
- The client never kept a reference to the video element, so frame capture
returned early and nothing was ever sent.
- /v1/images/{id}/classify passed detection dicts where the engine expected box
dicts (KeyError: 'width').
- Placeholder chrome (thumb, dashes, hidden groups) leaked on first paint.
Verified in Chrome with a fake camera: live 8-12 results/s, ~60 products in
view, product card and feature matching populated, photo 105/170 recognised on
image.jpg and 59/111 on add/image6.jpg, 0 console errors.
