HR & Payroll Platform
Internal system for staff time tracking, productivity pay, and gross-to-net payroll. Not yet in service — this deployment is the Phase 0 foundation.
Foundations
- ✓Repository, TypeScript strict mode, Vitest
- ✓Continuous integration: typecheck, lint, coverage, build
- ·Database schema and forward-only migrations
- ·Authentication with TOTP multi-factor
- ·Role-based access control
- ·Append-only audit log
Calculation engine
- ✓core-money — integer-cent arithmetic and allocation
- ✓core-time — civil dates and workweek overtime
- ✓core-comp — compensation models and the FLSA regular rate
- ·core-tax — withholding, FICA, wage-base caps
- ·Payroll run assembly, preview and approval
Notes
No employee, payroll, or compensation data exists in this deployment. The calculation packages are pure and carry no I/O, so they are verified by test rather than by inspection — see src/core, whose suites encode the worked examples from the requirements document.
