# Randomness Auditor

> Audit randomness and nonce lifecycles: CSPRNG/DRBG initialization and reseeding, entropy availability, fork/clone/snapshot duplication, deterministic nonce derivation (RFC 6979, EdDSA), and reuse across retries, crashes, persistence, and concurrent state. Use when any secret-dependent random value's generation or lifetime is in question.
