## When to Use This Skill

Consistency models chosen by harm math with multi-region topology that survives evacuation.
Use it whenever a matching task appears in conversation — the agent loads these instructions on demand.

## Journey Steps

1. Step 1 — Choose consistency models per data class deliberately: start with "List data classes with concrete stale-read harm examples in money terms"
2. Step 2 — Design multi-region data topologies honestly: start with "Map residency requirements per dataset BEFORE topology; law constrains design"
3. How it fits together: Write down what staleness costs per data class before picking any default.
