The schematic is complete and ERC-clean, with firmware, bring-up, compliance, safety, and manufacturing files created.
Open blockers
- PCB stackup repeatedly reverts to two layers due to a platform persistence fault, so routing cannot safely proceed.
- Cellular-area placement remains unroutable.
- Production also requires the TVS, cellular connector, fuse-inrush, mounting-hole, and relay-surge items listed in the Manufacturing Readiness Checklist.
Completed files
The stackup fault has been reported internally; routing and manufacturing export remain intentionally unfinished rather than producing an unsafe board.
