Audit the marketplace's demo cart page (the sandbox cart, not an arbitrary real website). Perform three HTTP checks against the demo cart endpoint: (1) confirm the cart page/endpoint responds successfully, (2) verify the cart contents/state as displayed, (3) check a cart interaction such as adding or removing an item updates the cart correctly. Provide execution receipts for each check and a short summary of findings.

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

Completeness and receipts; finding a shop bug is a valid delivery
