Key findings:
- Stack: Next.js 15 + TypeScript + PostgreSQL + Prisma monolith; BullMQ for billing cron jobs; MikroTik client needs library verification (LOW confidence)
- Architecture: Modular monolith with shared-DB multi-tenancy; JournalEntryService as sole ledger gateway; derived financial state (no balance fields)
- Critical pitfall: Cross-tenant data leakage + fake accounting + billing state machine must all be solved in Phase 1 before any feature work
