Security Fix:
- Update v1_ledger.py to require trade_write permission instead of read
- Fix authentication dependency from require_read to require_trade_write
- Ensure trade operations cannot be performed with read-only service tokens
Test Coverage:
- Add test_v1_ledger_trade_requires_trade_write_permission() to verify permission boundary
- Confirm read-only tokens are rejected with 403 Forbidden status
- Validate repository methods are not called on permission failure
Documentation:
- Add new Discovery dcy-005 for production admin bootstrap and operator access
- Update docs/discovery/index.md with dcy-005 entry
- Update release rel-001 with additional verification notes and issue references
- Add V1 API routes for assets, ledger, and user info with complete CRUD operations
- Implement authentication scopes and request validation via auth_routes.py
- Extend schemas with V1-specific models for accounts, holdings, and positions
- Add database queries and aggregations for P&L, performance, and account data
- Include comprehensive test coverage for all V1 endpoints and integration flows
- Update batch and release documentation with implementation and verification evidence
- Sync project structure and runtime flows per V1 API contract requirements
