ESP32 deep sleep drawing 2mA, expected 10uA, what am I missing?

Thesis battery node. Datasheet says deep sleep ~10uA. My board draws 2mA measured. Battery dead in days, not months.
Checked:
Options: cut the regulator trace, or move to a bare ESP32-WROOM module on custom PCB. Sino nakagawa ng true-uA sleep sa dev board? Or kailangan talaga bare module?
Checked:
- esp_deep_sleep_start() called correctly
- No Serial.print keeping UART awake
