Mesh

Distributed Credibility Mesh

The Mesh layer enables federated credibility governance across multiple DeepSigma nodes. Each node maintains its own credibility state and participates in consensus to produce tamper-evident, cross-organization trust scores.

Node Roles

Role	Purpose
Edge	Ingests local decision episodes and computes local credibility
Validator	Verifies claims and drift signals from edge nodes
Aggregator	Combines validated scores into composite cross-node credibility
Seal Authority	Issues tamper-evident seals for consensus decisions

---

Architecture

  Edge Node A ──┐
                ├──→ Validator ──→ Aggregator ──→ Seal Authority
  Edge Node B ──┘

• Push — edge nodes push events to validators via HTTP/msgpack
• Pull — aggregators pull validated batches from validators
• Consensus — quorum-based agreement before seal issuance

Transport

Protocol	Package	Use
HTTP + msgpack	httpx, msgpack	Default inter-node transport
In-process	—	Single-node / test mode

Install: pip install -e ".[mesh]"
