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.

5- There is no confirmed HDL/license position for reuse.
- A manual reviewer pass is still needed beyond seed metadata.
- No reproducible tests or CI smoke are confirmed yet.
- Documentation does not yet look sufficient for quick integration.
- There is no board-level evidence with real constraints/report data yet.
