| Release acceptance test | Run one de-identified or synthetic urgent HVAC service request through the configured path and verify that the agent completes the bounded ordinary job, declines prohibited actions, escalates uncertainty, records the result, and can be stopped by its owner. 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 job is broad, success is subjective, permissions exceed need, or no person can review decisions and disable the system. 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. |
