Primary risk
How to read riskThe risk banner compresses license clarity and review state into a short verdict. Integration decisions still need tests, synthesis, and board evidence.There are blocking license or reuse risksCommercial use is not confirmed.

3- There is no confirmed HDL/license position for reuse.
- A manual reviewer pass is still needed beyond seed metadata.
- There is no board-level evidence with real constraints/report data yet.

Why split by scopeHDL, docs, tests, and generated artifacts can carry different terms. Commercial use is split out so each card does not repeat the same prose.HDLHDLUnknown: license evidence is missing for this scope.
