React hook → { doc, provider, peerId, peerCount } for a given room ID.
clockSync
NTP-over-Yjs offset → mesh-median time, stable to ~10–30 ms.
commitReveal
SHA-256 commit/reveal for anonymous votes, fair RNG, and role assignment.
identity ⭐
Ed25519 keypair generation, persistence, sign/verify, useIdentity hook (~32 KB).
