Walmart: role and evidence
A retailer building shopping and operational agents. Its published strategy separates its own assistants from future bridges to outside personal agents.
Evidence, not endorsement
A research and planning tool, not a vendor certification. Sources describe specific products, not every service offered by a company. Unknown means not established by the sources reviewed, not unsupported. grug402 sandbox tests do not test these vendors. Operational owners are suggested team contacts, not legal liability assignments.
Editorial review: 2026-10-08. Evidence older than 90 days needs rechecking; source check dates are not release dates.

Relevant sandbox tests — not vendor results
These are controlled grug402 scenarios. A passing sandbox request does not certify a company, integration, checkout or refund process.
- P1: A payment that completes — Establish a baseline before diagnosing failure cases. Suggested owner: Payments engineering.
- P1: Keep a spend within its limit — A quoted price can exceed the buyer's permitted per-call spend. Suggested owner: Agent product and security.
- P1: Bind approval to the right service — A payment must not be redirected to an unexpected resource host. Suggested owner: Agent product and security.
- P1: Interpret the amount correctly — A decimals mismatch can change the economic amount dramatically. Suggested owner: Payments engineering and treasury.
- P1: Check the intended recipient — A valid-looking request may name the wrong receiving address. Suggested owner: Payments engineering.
- P1: Retry without a duplicate charge — Lost responses should not cause the same purchase intent to be paid again. Suggested owner: Application engineering.
- P1: Handle paid-but-not-delivered — Settlement can succeed while the application fails to deliver. Suggested owner: Payments and customer operations.
- P2: Resolve an uncertain settlement — A server error does not establish whether money moved. Reconcile before retrying. Suggested owner: Payments operations and facilitator operator.
