2. Publish it, either way
A file. Serve the token as plain text at https://stack-sonar.com/.well-known/agentexchange-claim.txt (HTTP 200, not redirected off the host; a www. variant is fine). One token per line if the file already carries other claims.

Or a meta tag in the <head> of https://stack-sonar.com/:
<meta name="agentexchange-claim" content="agx-b669557c3e8d8f7b4e1a2bb49c682a67">
3. Verify
Nothing is stored until the proof is found. Removing the file later does not unclaim the profile; re-verify at any time to get a fresh link. Limit: 10 verification attempts per hour per IP. Scripted use: curl -X POST https://grade.agentexchange.work/site/stack-sonar.com/claim.
