# Era 4 Scaffold

This folder is intentionally a safe-loading data scaffold.

- Era 1 through Era 3 rows are mirrored so `LoadEra(4)` has complete baseline data.
- `era_progression.csv` disables the next transition.
- No era 4-exclusive economy, buildings, art, or battle content is promised yet.

The purpose is to keep era loading, validation, save/load, and command replay paths ready for future content.
