## Entries

- [Stated Invariant](https://banes-lab.com/records/architecture/stated-invariant.md): A design rule that an invariant a topology relies on is written with its property in a form that could be false, the set it ranges over, the parties it binds and the thing that would object if it stopped holding.
- [Contradicted Invariant](https://banes-lab.com/records/architecture/contradicted-invariant.md): A defect in which one surface states the opposite of an invariant another relies on, so every mechanism faithfully implementing either statement stays green while the invariant is violated.
