Disclosure is a product feature.

Every public Reddit post or comment created as a Larp task must include the campaign disclosure line (FTC-style). Hidden promotion is out of scope.

1. The advertiser writes the line on the campaign brief.
2. The ambassador pastes it into the public Thing they author on their own account.
3. Automated verify looks for the line on the fetched permalink.
4. A platform operator confirms it before escrow is awarded.
