Added ER.svg and database_schema.md to document the logical data model. Refactored and extended transaction validation in blockchain/abci.go to enforce ID prefix rules, entity existence, and uniqueness for promises, commitments, commiters, and beneficiaries. Updated lbc_sdk dependency version in go.mod and go.sum.
