- [01-05]: Next.js 15 route params wrapped in Promise<P> — HOF awaits params before passing to handler
- [01-05]: subscriberCount hardcoded to 0 in admin API — Subscriber model added in Phase 2; API shape is forward-compatible
- [01-05]: Dual guard strategy for /admin: middleware.ts (JWT edge), layout.tsx (server), API handlers (endpoint) — three defense-in-depth layers
- [02-01]: ISP COA has 28 accounts (5 category headers 1000/2000/3000/4000/5000 + 23 leaf accounts) — hierarchical for reporting
- [02-01]: Subscriber Credits (1150) is contra-asset with CREDIT normal balance — correctly reduces AR for overpayments
- [02-01]: seedChartOfAccounts receives Prisma tx client — works inside createTenant $transaction for atomic provisioning
- [02-01]: Accounting periods created on-demand via getOpenPeriod() — not pre-seeded on signup (no wasted periods for unused months)
- [02-01]: close route uses closure pattern over withPermission HOF — withPermission doesn't support dynamic params directly; POST fn closes over Next.js params
