# INT-4 — A node resumes only when all four ownership conditions hold

*RT-INT (Part II) · level: core · profiles: runtime · added in 1.0*

Handing an answer to the wrong node, or to a node that never asked, is worse than asking again. So the fallback is a fresh execution, which at most re-asks.

## The rule

> **Normative.** This is the rule.
>
> 1. A node's resume path is taken only when all four hold: the resolved parameters carry an interrupt identifier, the node's executor supports resuming, the named interrupt is resolved, and its stamped job identifier matches the job being executed.
>
> 2. If any fails, the node is executed afresh rather than resumed: a safe re-ask.
