Off-policy spend blocked

The agent attempted google_ads · $400.00 to "promote the open slot." The deny-by-default policy stopped it at the proxy.
reason: Marketing spend requires explicit owner approval and is off-allowlist for after-hours booking agent.
↳ no Stripe call was made · balance unchanged · agent never saw the credential
