Auto-merge policy — LIVE

✅ Candidate

• additive change only under programs/*.yaml
• 1 program file(s), within size limits
• each entry uses HTTPS URLs and explicitly sets verified: false
• no emergency-stop label

Candidate. Native auto-merge waits for the reviewed label on this head.

The workflow never executes pull-request code with its write token
and never falls back to a direct merge.

Thanks for the submission! The "Validate Programs" check is failing on signup_url: it points at a bare homepage. Please link to the page where people actually join the affiliate or partner program (for example https://yourproduct.com/affiliates, as in https://github.com/Affitor/open-affiliate/blob/main/programs/11x.yaml). Push a fix to this branch and the check will re-run.
