## Evidence grades

| Grade | Meaning |
|---|---|
| A | Government, regulator or standards-body source |
| B | Exact manufacturer documentation or official product-family documentation |
| C | WoodAge project record, signed BOQ or site measurement |
| D | Transparent derivation from cited A/B/C evidence |

## Interpretation boundary

`source_reviewed` means the source and annotation were checked during the release build. It is not a claim of human contract approval. Project drawings, site conditions, exact product documents and signed agreements control.
