How should a candidate become fabrication-qualified?

[mrcha033]

The current golden candidate is not fabricated. The intended path is: resolve supplier evidence, select and qualify the U2.57 via-in-pad process, fabricate the exact hash-addressed candidate, then publish assembly photos, current-limited power-up, rail measurements, firmware/interface results, thermal/SI/PI/EMI evidence, and remaining gaps. Ask questions about the evidence contract or propose a reproducible validation step.
