bts4140n: etch along the lead row, tab up; full MPN text (service-occt 1.9.3) (service-occt 1.6.0, from the plain STEP)
bts4140n: component.models_3d pose record per STEP (Z-up, seated z=0, pad-centre origin, identity binding)
Brief states the pinout check that actually ran (was an unconditional "Datasheet-verified pinout")
bts4140n: laser-etched CAD + chip hero (factory 2.0.0 backfill)
bts4140n: publish the laser-etched STEP alongside the bare one
orderable attributes: rebuild .lbr with adom-lbr 2.18.0 so MPN, MANUFACTURER and the distributor part numbers reach <te…
fix footprint: SOT-223-3_TabPin2 -> SOT-223 (symbol has pins 1,2,3,4; the old footprint left pad(s) with no net)
pin 1: carry the footprint's marker into the .lbr, the viewer and page.json (silk-marker, drawn, top-left)
