Stage 2 build is complete:
- U3 TPS63802DLAT installed and wired
- L3 replaced with Murata
DFE201612E-R47M=P2
- R13/R25 feedback divider added
- Critical switch nodes reported correctly separated: U3 pin 7/L3 pin 2=
REG_SW2; U3 pin 9/L3 pin 1=REG_SW1
- PG is explicitly unconnected;
PGOOD_N unchanged
- Initial ERC reported clean
The independent audit finished, but I cannot retrieve and reconcile its final report because no ACUs remain. That reconciliation, the full 12-item report, and final Stage 2 sign-off remain pending; no further project changes should be made until the audit is reviewed.
