Shows how a blueprint declares error types, stops a run with an error, handles one error with a business fallback, and passes the others on to the caller

A complete validation rule library: an entry blueprint, four ready-to-use rules, and a deliberately sloppy blueprint that breaks every one of them. How it fits together: Governance Rules is the entry — the only blueprint that runs. It calls each rule and returns everything they found. Credit Limit Check is not a rule; it is the demo that violates them. How to use it: 1. Release this project, and in the release dialog open Options and tick "Mark as validation rule library". An ordinary release offers no rules. Confirm which blueprints are rules — the ones the entry calls are already ticked. 2. Open the project you want checked, go to Project settings → Validation rules, and add the rules you want from this library. 3. Their findings appear in that project's Findings list. They never block anyone from working, and only a project owner can add or remove them. Rules only ever run from a release, so what checks your projects is always a version someone approved — publishing a new version changes nothing until an owner accepts it. To watch the rules fire, add them to this project too: Credit Limit Check breaks all four. The library also reports its own rule blueprints — "Credit decisions must log" fires on anything named after credit, which includes the rule checking for it. That is the rules working, not a bug.
