# INT-3 — Resolving an interrupt resumes only a paused run

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

Answering a question must never restart a run that is already moving. The reset and the resume are two steps in that order, which is what keeps two executors off the same run.

## The rule

> **Normative.** This is the rule.
>
> 1. Resolving an interrupt locates the job it interrupted by the job identifier stamped on the interrupt, and returns that job to pending unconditionally.
>
> 2. Only then, and only if the run is paused, is the run resumed, through the engine the run declares (ORC-13), never a different one.
>
> 3. A run that is not paused is left strictly alone and must not be re-entered.
>
> 4. A stateless run has nothing to resume, and resolution is a no-op for it.
