| Release acceptance test | Run one de-identified or synthetic urgent HVAC service request through the configured path and verify that an eligible missed call triggers once, identifies the business, handles reply and opt-out correctly, and creates a visible callback or next-step record. Record the expected state, actual state, exception owner, and corrective action before release. |
|---|
| Stop condition | Do not release or continue the automated path when the caller reports a possible safety hazard, the service promise is unavailable, or diagnosis, price, scope, or dispatch priority requires a qualified person, or when the caller's permission, number type, call outcome, quiet-hour rule, duplicate state, or response owner cannot be determined. Preserve the record and route the case to the named human owner. |

| Human boundary | Qualified HVAC staff retain safety judgment, diagnosis, dispatch priority, pricing, scope, repair recommendations, and job acceptance. The configured system may capture and route approved facts but cannot diagnose equipment or improvise emergency instructions. |
