# ERR-9 — A run whose every failure was handled completes

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

The verdict is computed from unhandled failures, not from failures. One unrouted failure fails the run no matter how many routed ones accompany it.

## The rule

> **Normative.** This is the rule.
>
> 1. A run finishes with status completed when every failed unit of work in it carries the error-routed marker, and fails when any failed unit of work does not.
>
> 2. A routed failure is still announced on the ordinary "unit of work finished" channel, so subscribers see it and discriminate on its status.
>
> 3. A failed tool invocation always counts as handled: a tool failure is delivered to its consumer as a recoverable result.
