Step 1 of 3 · prove the domain

Claim lmi3d.com

Pick one way to prove you control the domain. Each method issues a single-use token.

Work email2 minutes

A single-use link sent to a mailbox at @lmi3d.com exactly: no subdomains, no address at another domain. The link works once and expires in 30 minutes.

DNS TXT recordstrongest proof

Publish one TXT record at _itha-challenge.lmi3d.com. Needs DNS access; the token stays valid for 7 days.

.well-known file7 days

Put the token in the verification field of https://lmi3d.com/.well-known/itha.json. Fetched over HTTPS from that exact host; cross-origin redirects are refused.

If two people claim the same domain, the first token to pass wins and the other claims are superseded. Nothing is published until the facts are approved in step 2.
