Notes: The code implements a guarded, cache-accelerated path to sign a message via an external SnapController. No explicit malware indicators detected. Primary risks relate to API design and cache semantics: entropySourceId is currently unused in the cache key, which could cause mismatches between the signing policy and cached signatures; potential replay/reuse concerns if identical messages are signed for different intents without provenance. Recommended improvements: validate message format and provenance, incorporate entropySourceId into cache keys or policy checks, add audit logging, and implement cache eviction/invalidation rules to prevent stale signatures.
