Start with the preview.
Explore the product approach without creating an account or sharing personal content.
1. Understand the availability state
The website describes Merism in staged development. Visiting the preview does not create an account, join a mailing list, or grant an entitlement.
2. Follow the walkthrough
Open the demo and advance from Problem through Evidence and Proposal. At Authority, explicitly approve the sample calculation. Only then can the walkthrough move to execution.
3. Check the receipt
Verification recalculates the total from the sample evidence. A passing result reaches Proof. The failure option demonstrates why an executed step can still be unverified.
4. Clear the sample
Use Reset example or reload the page to clear temporary sample state. There is no file upload, live model call, external action, or persistent browser record in this walkthrough.
