John Lauer 0.1.41: flat MPN mark; local OpenCascade only with the user's OK 08134d8 6d ago

AI Flow 0.1.41

  • The MPN mark is flat. The laser-etch service returns an extruded solid for every glyph (side walls and underside); on a SOT-23-6 that added 1,760 triangles to a 920-triangle part. adom-aiflow-etch now keeps only each glyph's top face as a zero-thickness sheet, lifted 0.01 mm: the same look in KiCad 10 and step2glb renders for 359 triangles. ETCH_SOLID=1 keeps the solids.
  • No silent OpenCascade install. Turning the part and merging the mark need OpenCascade locally (about 1.3 GB) until the service keeps colours, turns the part and writes flat marks itself (adom/adom-chip-laser#2). Adom's rule is that STEP geometry work happens on the shared services, so the tool now refuses unless the user has agreed (AIFLOW_ALLOW_LOCAL_OCC=1), and says so.
