Institutional review
Example evidence artifact
A synthetic Australian livestock case, carried end to end. The artifact states what evidence is present, what was reviewed, which profile was applied, what limitations remain — and what it does not establish.

}Trust states
Read the artifact in four separate registers
Technical integrity
All included records hash-verified against their commitments.
Scientific interpretation
Efficacy is determined by scientific evidence outside this artifact.
Method compatibility
Assessed against au.livestock.v1; one material gap remains.
External reliance
No buyer, verifier or institution has recorded a decision.
Verify it yourself
Local verification
- download the artifact and its fixtures from the tagged release;
- run the CLI verifier against the artifact digest;
- reconstruct the source manifest from your own store;
- compare expected outputs with the published fixture outputs;
- reproduce the documented failure cases.

Boundary
What this artifact is not
A valid signature is not proof of scientific efficacy. Method compatibility is not registry approval. Artifact generation is not external acceptance. Payment is not evidence quality.
