Work done

Verified the current schematic already has key infrastructure placed and partially net-labeled for a V3C48-class Pico-ITX SBC: GPU slot J3, NVMe sockets U1–U4, PCIe switch placeholder U11, PD controller U13 with USB-A power switches U14–U17, boot flash U12, RTC backup holder J12, and ATX+DC ORing/eFuse U9/U8 with battery-module header J13.
Pulled web references confirming V3000-family I/O concept (DDR5/ECC + up to 20 lanes PCIe Gen4 arranged as x8 + 3x4) and filed an internal missing-part request to add the AMD V3C48/V3000 APU symbol/footprint plus SlimSAS SFF-8654 and a suitable PCIe Gen4 switch into the Flux library.
Reviewed ERC/DRC: ERC is currently OK for undriven nets, but DRC still shows 203 airwires and BOM/MPN review flags for J10, J4, J5.

Success criteria review

❌ Cannot replace CPU placeholder U5 with AMD Ryzen Embedded V3C48 because an implementable V3C48/V3000 symbol+footprint (or SOM/module with published pinout) is not available in the Flux library; TechPowerUp does not provide the required pinout/ball map.
❌ Therefore cannot complete DDR5/ECC wiring, SPI boot wiring to U12, RTC VBAT wiring to J12, or the required PCIe lane map (x8->J3, x8->SlimSAS, x4->Gen4 switch->U1–U4) in a production-correct way.
❌ Cannot clear DRC airwires because I cannot trigger auto-routing/auto-placement from the agent side (Flux limitation); you must run Auto-Layout in the UI.

Next steps

Provide a real V3C48/V3000 pinout source (ball-map/pin mux table) or choose a V3000 SOM with public connector pinout; once we have that (and/or once the library parts land), I can replace U5 and fully wire DDR5/ECC, SPI flash U12, RTC backup J12, SlimSAS, and the Gen4 NVMe fan-out switch.
In parallel, you can run Auto-Layout routing; after that I can re-run DRC airwire checks and help resolve remaining schematic/constraint issues.
