Verify it on your own machine

unzip cain42-ihvrk-svc-stcn.zip && cd cain42-ihvrk-svc-stcn
python3 verify.py            # offline: hashes, Ed25519 signature, recorded answers
python3 verify.py --live     # also re-send every request yourself and check the answers now

A claim that cannot be checked counts as a FAIL, never a pass. The live check is the one that depends on nothing we recorded.

The claims in this kit

#	Claim	Answer must contain
C01	stcn (catalog service): the demo completes (ok) -> ok = every step succeeded; refused = the service answered and refused a step, as this demo shows on purpose.	`["ok"]`
C02	Step 1: POST /api/analyze answers HTTP 200 -> This step succeeded in the reference run.	`[200]`

What it does not do: no written limits review yet; this kit shows the live service answered as recorded, not that every answer is right for every input

What this kit is, and is not

It shows what the live product answered to these inputs, and lets anyone check that again. It is not a third-party audit, a certification, or a promise about inputs not listed. This product has no written limits review yet.
