# ADR-012: Node/edge attribute schemas are Module entries, not Type.Any()
|
|
|
|
## Status
|
|
|
|
Accepted
|
|
|
|
## Context
|
|
|
|
At the DB storage layer, node/edge attribute schemas are arbitrary JSON Schema blobs (`Type.Unknown()`). But at the application layer, graph type definitions should have full type safety for their attribute schemas.
|
|
|
|
## Decision
|
|
|
|
At the application layer, node and edge attribute schemas are named Module entries with full type safety (`CallGraph.CallNode`, not `schema: Type.Any()`). At the DB storage layer, the meta-schemas (`NodeType`, `EdgeType`) still have `schema: Type.Unknown()` because the DB stores arbitrary JSON Schema blobs. The repository layer maps between the two: Module entries are the application-level validation, the DB is the persistence layer.
|
|
|
|
## Consequences
|
|
|
|
- Compile-time type safety for graph type definitions
|
|
- Runtime validation via `Value.Check(Module.EntryName, data)`
|
|
- DB layer remains generic — any JSON Schema blob is accepted for storage
|
|
- Validation boundary is the repository layer, not the database
