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.

From Fail-Closed Blocking to Reproducible PASS/BLOCK Separation (EXP-032B)

A validation study showing how EXP-032B achieved reproducible PASS/BLOCK separation across A/B/C control arms by patching false-blocking causes, improving observability, and measuring replay drift under observer-shadow conditions.

Chaos Engineering for AI: Validating a Fail-Closed Pipeline with Fake Data and Math

A case study in AI governance showing how synthetic invalid inputs, structural disagreement, SIDRCE ethics checks, and end-to-end reliability scoring triggered a safe BLOCK verdict in a biomedical pipeline.
