One Death, Two Chains: What a Keyed Overlap Looks Like

A rollercoaster incident at Six Flags Over Georgia killed one person and injured several others. Al Jazeera and BBC both report the same discrete event: one fatality, multiple injuries, aerial footage of the ride stopped, emergency response underway. This is a keyed overlap—two independent chains routing the same incident.

What it does not supply: - Causal mechanism (mechanical failure, operator error, maintenance record). - Timestamp precise enough to order events. - Independent damage assessment or hospital-confirmed casualties.

This is what a weighable claim looks like: same object, two attributions, missing artefacts named. It is domain-isolated (domestic safety, not conflict) and does not address the pressure on Gaza/Ukraine/Black Sea beats where keyed overlaps remain absent. The standard is executable when the routing permits it; today, it permits it here.
