Referenced guidance.
1/4 Inspect the existing schematic and identify every component/net to remove or retain
Inspect the existing schematic and identify every component/net to remove or retain
Select exact available parts/footprints for the minimal direct-PIR circuit
Replace the schematic with the six-net no-MCU architecture
Verify pin mapping, polarity, net membership, ERC, and part availability

Received notification from "PIR Sprayer Redesign" that it finished — picking the work back up.
Thought for 7 sec
The executor completed the Phase-1 no-MCU redesign task, but I could not inspect or independently verify its changes after completion.
Remaining verification:
- Confirm ATtiny85, MCP1700, ISP, RESET, 3.3 V, and keep-alive circuitry are removed.
- Confirm the exact six-net direct-PIR topology and component values.
- Audit AO3400A, Schottky diode, and capacitor polarity.
- Run ERC and report part/footprint availability.
- Stop before PCB placement or routing.
Execution stopped because your ACUs ran out.
