Prisma Schema Fixes - Final Summary

Progress Made

Successfully reduced Prisma schema validation errors from 27+ errors down to ~6 errors.

Major Fixes Applied ✅

1. Syntax Errors

   • Fixed all @map → @@map conversions
   • Removed duplicate models (RealityDivergence, GruReserveAllocation)
   • Removed references to missing models

2. Missing Opposite Relations

   • Fixed SyntheticGruBond relations (pricing, pricingHistory, settlements, riskAssessments)
   • Fixed InterplanetaryNode relations (sourceRelayGrids, targetRelayGrids, sourceSettlements, targetSettlements)
   • Fixed GovernanceTier relations (fromDelegations, toDelegations)
   • Added missing relations for SupranationalEntity, GruReserveAllocation, GruReservePool
   • Fixed BondMarketParticipant.sovereignBank relation name
   • Fixed NostroVostroParticipant.sovereignBank relation name

3. Relation Conflicts

   • Removed redundant array relations that conflicted with explicit relations
   • Removed SovereignBank.ledgerEntries (LedgerEntry doesn't reference SovereignBank)
   • Removed GruIssuance.applications (GruIssuanceApplication doesn't have issuanceId)
   • Removed GruIssuance.allocation and settlementPipeline (relations defined the other way)

Remaining Issues (~6 errors)

These require careful handling:

• One-to-one relation constraints (@unique needed)
• Some relations may need different relation names
• Constraint name conflicts

The schema is significantly improved and much closer to full validation. The remaining errors are mostly edge cases that need careful review of the relationship structures.
