Core Implementation - 100% MVD COMPLETE ✅
Validator Service Architecture
- REST API validation endpoints (transaction submission, memory pool stats)
- gRPC peer communication (RequestVote, ValidateDocket, GetHealthStatus)
- Admin control endpoints (start/stop validators, status queries, manual processing)
- Background services (memory pool cleanup, automatic docket building)
Domain Models
- ✅ Docket.cs - Blockchain block with consensus votes
- ✅ Transaction.cs - Validated action execution records
- ✅ ConsensusVote.cs - Validator votes (approve/reject)
- ✅ Signature.cs - Cryptographic signatures
- ✅ Enums: DocketStatus, VoteDecision, TransactionPriority

Admin Endpoints (/api/admin)
| Endpoint | Description |
|---|---|
POST /validators/start | Starts validator for a register |
POST /validators/stop | Stops validator |
GET /validators/{registerId}/status | Gets validator status |
POST /validators/{registerId}/process | Manual pipeline execution |
