Overview

Per-segment frustration attribution. Attributes incidents to segments by object identity (e.equal?(incident)) so a same-millisecond Meta boundary cannot mis-attribute one.

IMPORTANT: works on the RAW detector output (before refine_incidents de-noise), so dead_count may EXCEED /analytics/frustration for the same URL. Intentional: completeness over precision (no rages a de-noise rule might withdraw are missed).
