Module multilog 

Multi-log attestation and gossip quorum (SIGNATIF §13).

• MultiLogPolicy {m, k}: a federated authority’s artifacts must carry inclusion proofs from at least M of K independent logs — no single log operator controls the record.
• GossipQuorum: the signed tree head a verifier relies on must be witnessed by at least N independent witnesses.
• MultiLogAttestation: the verification side — which logs produced valid inclusion proofs.

Structs

GossipQuorum

Gossip quorum verification: at least min_sources distinct, independently-signed observations of the same tree head.

LogInclusion

One log’s inclusion-verification result.

MultiLogAttestation

The set of inclusion results evaluated against a policy.

MultiLogPolicy

M-of-K multi-log policy.

WitnessCosignature

One witness’s signature over a signed tree head.
