I’ll route the PCB now. I’ll first check the layout/review state for routing prerequisites and stale traces, then run the autorouter and verify remaining DRC/airwire issues.
Prerequisites look good: the board is 25 × 25 mm, 2-layer, components are placed, and the only blocking layout issue is 3 airwires. I’m starting the autorouter now.
Routed the board successfully and widened all routed traces/nets to 1.0 mm. Routing DRC is clean now — no airwires or trace/copper errors remain.
Unrelated remaining review items: floating pins on R4/C2 and missing MPNs on generic passives, which I did not change because you only asked for routing.
