Phase H – Scene editor
Draw lines and rectangles (mm, +Y up). Use presets (shared laser parameters) or a per-entity override in the parameter column; order items in the job tree, then submit as scene_v1. Backend geometry path: /api/v1/jobs/scene → /api/v1/jobs/dxf/{id} (load / run / stop). Optional laser block is stored for future RTC use.
RTC session
Mock = no hardware. Real RTC = UDP Remote Interface to the card (same R_DC_GET_STATUS handshake as POST /rtc/connect with mode: ethernet).
RTC: —
RTC activity log — same host as this page.
Canvas
Tool:
Axes and tick labels are drawn in Konva (same pan/zoom as the grid). Units: millimetres; origin (0, 0); +Y up on screen (same convention as the DXF demo).
