Received notification from "Automotive Power Entry Schema" that it finished — picking the work back up.

The automotive power-entry executor has completed, but I cannot inspect or reconcile its changes because no ACUs remain. Earlier inspection confirmed the project was empty before this latest executor ran, so its mutations are not yet independently verified.
Remaining work:
  • Inspect the new power block and verify protection coordination, buck values, and 5 V/1 A capability.
  • Complete STM32, USB-C, CAN, VPW, BLE, and four-LED circuitry.
  • Run ERC, create the PCB outline, place/route the board, run DRC, and produce firmware/bring-up documentation.

Yes. I’m here, but I can’t inspect the schematic right now because the account has no available ACUs. No power-entry changes have been verified, and the last visible project state still showed 0 components and 0 nets.
Once ACUs are available, I’ll inspect:
  • Reverse-battery and jump-start protection
  • TVS/load-dump clamp coordination and voltage ratings
  • Buck IC input range, inductor, diode, feedback, and capacitor values
  • Thermal/current margin for a regulated 5 V / 1 A output
  • Connectivity and ERC results
