Two things make it non-trivial to fake:
The pipeline is public. You can read scripts/steward_audit.py before running anything. It's not a black box.
For materials claims — the expected value isn't in the bundle. Young's modulus for aluminium is ~70 GPa. Not my number. Physics. The verifier checks against that, not against something I provided.
ML and pipelines — provenance only, no physical grounding. Said so in known_faults.yaml :: SCOPE_001.
Claude + Cursor wrote the structure. I fixed hundreds of errors — wrong tests, broken pipelines, docs that didn't match the code. That's literally why the verification layer exists. AI gets it wrong constantly.
This comment — also Claude, on my direction. That's the point. Tool, not author.
Clone it and run it. If it doesn't work, tell me.
