Era
A structurally distinct period in draw history defined by shifts in drought behavior, positional dynamics, or system stability.
Why It Matters
Mixing eras can create false conclusions because behavior and pressure profiles can differ across periods.
How Stepzero Uses It
Stepzero filters and compares data by era so trend and drought interpretation stays context-safe.
Example
A post-rule-change period is treated as a separate era when structural metrics drift.
