How do you know when your entire AI pipeline is wrong — not just one model? (EXP-033)

EXP-033 shows how to validate an entire AI pipeline, not just one model, using five-gate checkpoints, reproducible PASS/BLOCK parity, AlphaGenome on/off testing, and fully traceable governance decisions.

What AI Changed About Research Code — and What It Didn’t

The old bottleneck was writing the code. The new bottleneck is proving that the code still means what the theory meant.
