ChargeGuard Gateway - PCB layout review status: schematic power tree review is clean; remaining work is PCB-layout-only cleanup. Current DRC inventory: 136 Overlapping Copper, 56 Floating Copper, 88 Airwires, 0 Missing Footprints, 0 Invalid Layer, 0 Important Overrides. Priority 1: protected input and power-path regions around VIN_PROTECTED, VIN_FILTERED, +5V_MAIN, +3V3_MAIN because these can block reliable routing and copper pours. Manual PCB editor tasks: remove/reshape overlapping copper, reconnect broken traces or redraw routes causing airwires, delete stranded copper islands, inspect ambiguous pad-to-trace shorts around power devices and connectors. Agent-preparable tasks: maintain issue inventory, classify nets and priorities, preserve stackup/documentation, define DRC recheck loop, and guide Auto-Layout sequencing after manual copper cleanup. Recheck loop: fix one issue class or one critical region at a time, rerun DRC, confirm counts decrease, then move to next batch until airwires/floating copper/overlaps are zero. Completion checklist: 1) clear power-path overlaps, 2) remove floating copper islands, 3) close all airwires, 4) rerun DRC after each batch, 5) confirm clean layout before manufacturing export.
