[3m1n3nc3]

Description

Replace binary floating-point money fields with exact asset units and explicit asset identity.

File Location

learnault-api/prisma/schema.prisma, monetary utilities, migrations, and affected tests

Design Reference

API Roadmap Phase 0: Replace Floating-Point Monetary Storage.

Dependencies

• Status: Blocked
• Blocked by: Feature: Repair Clean Install and Prisma Generation
• Blocks: API Phase 1 wallet schema and later rewards/payouts

Tasks

• Inventory all persisted and calculated amounts using Float or JavaScript number
• Choose integer stroops/asset units or exact decimals and rounding rules
• Persist asset code, issuer, network, and decimals where required
• Create checked forward migration and rollback notes
• Prevent implicit number coercion in serializers and arithmetic
• Test conversion, rounding, overflow, and boundaries

Acceptance Criteria

• No persisted monetary amount uses binary floating point
• Asset and unit are explicit
• Unsafe legacy conversion fails visibly
• Migration and arithmetic tests pass

Verification Evidence

• Attach schema diff, migration dry-run, and exact-arithmetic tests
