# Standards

Constraints for this codebase. Referenced from code comments by filename, so
these names are stable - do not renumber or rename them.

- [deletion](deletion.md) - what bulk delete does, and what it refuses to destroy
- [filtering](filtering.md) - the filter expression language, and how it fails closed
- [naming](naming.md) - how modules, functions and columns are named
- [quotas](quotas.md) - plans, limits, and how quota is consumed
