ZeroBeacon Trust Harness — the PayPal gate

An AI agent proposes a purchase. The harness audits and verifies the proposal before any money moves. Only a measured pass creates a PayPal sandbox order; capture records the executed payment in a chained receipt ledger. A tampered claim is refused before PayPal is ever called.

Tamper: point the same clean manifest at work that actually contains a proof gap (a sorry)

Untampered, the manifest honestly describes clean work (0 sorries) and the gate passes. Tampered, the audit re-measures the real files, finds the gap the manifest denies, and the flow refuses — no PayPal order exists.

3. Verdict

Nothing run yet.
