Entropy Quality Notes

• Raw source output can be biased and structured.
• Conditioned pool output is the operational path for cryptographic use.
• For deep interpretation, run profile-based analysis and inspect verdicts.

Adding a New Source

1. Implement EntropySource in crates/openentropy-core/src/sources/<category>/.
2. Define SourceInfo with mechanism and platform requirements.
3. Register source in the category mod.rs.
4. Add tests and document the source in the corresponding docs category page.
