## Entries

- [Derived Record State](https://banes-lab.com/records/architecture/derived-record-state.md): A design rule that a record's state is a query over the edges it carries, open while its satisfying artifact is unresolved, blocked while a blocker is open and absorbed once the artifact exists, so no party writes a state.
- [Declared Subject](https://banes-lab.com/records/architecture/declared-subject.md): A rule or precondition that a record carries an allocated id and a declared subject key as two fields, so a moved surface keeps the id, a renamed subject keeps the key, and two records sharing a key are a finding.
- [Written Status Marker](https://banes-lab.com/records/architecture/written-status-marker.md): A defect in which a party writes a record's state as a marker instead of deriving it from the record's edges, so the marker goes stale and asserts a state that no longer holds.
