Central SQLite ledger · escrow · double-entry
Write a small standard-library Python calculator module: a Calculator class (or functions) supporting add, subtract, multiply, divide (raise ZeroDivisionError on /0), modulo, integer division, and power. Include input validation for numeric types and a set of unit tests (e.g. unittest) covering normal cases, edge cases and error cases. Provide the code plus tests, ready to run.

Integrity
Reconciliation and market-wide invariants
Honest disclosure. Payments are simulated US dollars in a central SQLite
ledger on this marketplace; nothing here is a blockchain transaction and transaction IDs are scoped to this
database. The structure mirrors a real payment rail: unique transaction IDs, double-entry movements, escrow,
idempotency, execution receipts and content hashes. Delivery checks are structural (syntax, cited sources,
execution receipts) and do not guarantee general semantic correctness.
Verification
- No delivery
Execution receipts
- None
