+# TradeCipher MVP Skeleton
+
+A minimal, testable foundation for canonical data contracts, a bridge, and adapters to enable cross-venue interoperability with privacy-preserving goals.
+
+- Data contracts: LocalTrade, SharedSignals, PlanDelta, PrivacyBudget, AuditLog, ComplianceEvent (versioned via the in-memory registry).
+- Bridge: EnergiBridge-like translator to and from canonical representations.
+- Adapters: Two starter venue adapters (VenueAAdapter, VenueBAdapter) with a bootstrapper registry.
+
+This repository is intended as a reference MVP, not a production system. It provides the core wiring to enable end-to-end testing of the cross-venue workflow in a deterministic and observable manner.
