Record: `arch:self-describing-structures`
Kind: principle

## Repair

- Refactored by: Add Type Tags, Add Schema, Add Manifest
- Detected by: missing type/schema markers
- Violated by: data requiring external hidden assumptions
- Measured by: metadata completeness
- Enforced by: [schema validation](https://banes-lab.com/records/arch/schema-validation.md)
