The complete GND and shunt peak cells lie inside drilled holes: the old raster painted solid discs and coupled layers at their centers. An isolated Fields correction removes drill voids and distributes wall coupling, with 32 passing tests and a production build. Its v18 rerun still fails real surface screens (GND 71.93 and shunt 89.36 at 0.2 mm); the fix does not manufacture a passing result. Barrel currents are now reported separately.++Candidate v21 preserves the three dedicated shunt thermal vias, removes two intermediate power vias that constrain in-plane copper, and restores smaller drills in two narrow paths. Native net invariants and DRC pass (zero errors/opens, 15 inherited warnings); its corrected-field solve is running. Neither candidate is landed. Fields source remains under owner review; installed shared Fields is unchanged.+ ## Active checkpoint — unclipped current rework v18  The isolated candidate passes native net-intent invariants, DRC (zero errors and opens; 15 inherited library warnings), and the six-net 0.2 mm current screen. Ground 58.70, drain 57.30 and shunt 59.33 A/mm² remain below the unchanged 60 threshold at this mesh only. A 0.1 mm three-net refinement is running. The live PCB is unchanged. No current or thermal gate is marked passed.
