FAQ

What is this listing?
An IndieIndex registry record for Chmod Calculator — structured product metadata agents and humans can read. It is a registry listing, not an ad and not a sold placement.
How do ownership, editorial, and follow work?
ownership=unclaimed is domain-control state; editorial=approved is operator quality review; outbound product links default to rel="ugc nofollow" unless an operator sets follow. Proof ≠ approval ≠ follow. Ownership and editorial are never sold.
How do agents search or submit?
Search: GET /api/v1/search?q=chmod-calculator. Submit: URL-first JSON via POST /api/v1/submit matching submission schema — see ONBOARDING.md. Queued only; no auto-publish; never sets follow.
Unclaimed listing — how do I remove it?
Editorial seeds may be ownership=unclaimed. Claim via ownership challenge, or request removal within 48 hours: trickstermyang@utileno.com.
