Royalties and blueprints

A blueprint is a name, a rule set, an author address and a royalty rate, stored in the BlueprintRegistry by publish(name, rules, royaltyBps). Anyone can publish. It cannot be edited after publishing; a changed version is a new blueprint.

How royalties flow

• A launch names a blueprint id. The launcher checks that the rules are identical to the published ones (same hash), or reverts with RulesMismatch.
• The author's royalty (between 0% and 25% of add-on revenue) is written into that pool and frozen.
• Each buy that produces add-on revenue credits the author's balance inside RuleCraftHook, in the pool's token.
• Anyone can call claim(account, currency); it always pays the account it was credited to. Nothing is pushed automatically.

Remixing

Anyone can start from a blueprint, change parameters and publish the result as their own. The original author earns nothing from a remix; royalties follow the exact blueprint a pool was opened with.
