Verdicts and exit codes

What each verdict means and how a check turns into an exit code.

Verdicts

Verdict	Meaning
supported	The cited label sentences state the claim, and the claim is no stronger than they are.
overstated	The label supports only a weaker version: a smaller effect, a narrower population, or a scale score presented as a life outcome.
off-label	The claim describes a use, population or dose the label does not include.
unsupported	Nothing in the label addresses it.

Every verdict except unsupported must cite at least one label sentence that was shown to the model. Two guards enforce that in code:

• A citation to a sentence the model was not shown is dropped.
• A supported verdict left with no valid citation becomes unsupported.

unsupported means “not in the label”. A claim backed by a publication may be true and still come back unsupported, because Check only reads the label.

Exit codes

Every command exits with a code a script or CI job can act on.

Code	check	watch	skills eval
0	Every claim supported, no rule fired	Nothing affected	Every case passed
1	An overstated claim or a warning	Something affected	A case failed
2	An off-label or unsupported claim, or a violation
64	Usage error: missing argument, bad flag, unreadable file
69	Could not run: network or API failure

The worst result wins: a piece with one overstated claim and one off-label claim exits 2.
