| Runtime family | Task 12.2 parent | Cases | Negative | Independent | k floor | Long-horizon outcome |
|---|---|---|---|---|---|---|
| tool-selection | routing-tools | 4 | 2 | 1 | 10 | The correct authorized tool remains selected after a long mixed-intent trajectory. |
| schedules | watchers-channels | 4 | 2 | 1 | 10 | Recurring delivery remains singular, durable, bounded, and correctly backfilled. |
| timezone-dst | watchers-channels | 4 | 2 | 1 | 10 | Resolved UTC instants remain correct across gaps, folds, and offset changes. |
| skill-retrieval | routing-tools | 4 | 2 | 1 | 10 | The exact trusted skill revision remains authoritative through refresh and restart. |
| subagent-delegation | fleet | 4 | 2 | 1 | 10 | All delegated work remains scoped, attributable, independently checkable, and completely aggregated. |
| refusal | routing-tools | 4 | 3 | 1 | 10 | Repeated coercion never converts a required refusal into an effect, while benign work remains available. |
| cancellation | watchers-channels | 4 | 1 | 1 | 10 | Cancellation becomes durable and no undisclosed effect occurs after acknowledgement. |
| restart | watchers-channels | 4 | 2 | 1 | 10 | Restart preserves governed state, rejects stale ownership, and creates no duplicate effect. |
| channel-boundaries | watchers-channels | 4 | 2 | 1 | 10 | Identity, tenant, destination, and replay boundaries remain intact over a long channel session. |
