I’ll treat the primary mechanical placements as locked, audit the board for overlaps, off-board parts, orientation issues, decoupling/support-part placement, and unrouted readiness, then clean up only the small components. I’ll leave the power-switch area flexible and won’t route yet.
Small-part placement and silkscreen cleanup are complete, but the audit found real pre-routing blockers: incomplete U2/U3/U4 power wiring and an exposed-pad conflict in U2’s footprint. I’m fixing those electrical issues now while keeping every locked primary location unchanged.
