Fixing ERC/DRC Errors and Routing
Inspect current board dimensions, layers, placement, routing state, and DRC/ERC
Repack every component onto the top side while preserving RF, sensor, connector, and power-stage constraints
Shrink the board outline to the smallest validated manufacturable size
Clean stale copper and validate routing feasibility
Route the board and resolve remaining ERC/DRC issues
Run final ERC/DRC/airwire checks and report status
Flux stopped
