What it does

• Server-side payroll: every payslip is computed by the API from attendance, bookings, advances and loans
• Closed write rules: every Firestore write is denied, so nothing sent from a browser can change a record
• Payroll pre-flight: generation is refused while a working day has no record, with the cost shown in rupees
• Capacity ledger: loans first, then advances, never more than the month earned, with any shortfall carried forward
• Commission stamped at sale: the rate is written onto each booking line, so a later change never alters past pay
• Username-only login: no email anywhere, scrypt-hashed passwords, account lockout and Firebase custom tokens
• Staff app: Schedule, Earnings and My hours on the phone, priced by the same functions payroll uses
• Register reconciliation: compares the paper register to the database line by line and reports every difference
