# Cursed settings

World-loaded setting registries of NTM: Cursed.

Nine world-loaded registries hold Cursed settings. Each registry has a fixed set of groups; each group is one JSON object of setting keys:

```text
data/leafia/leafia/<registry>/<group>.json
```

The first `leafia` is the entry namespace; the second is the registry namespace. Start from the corresponding file in the installed Cursed jar.

## Loading, replacement and validation

Settings load when the world opens and sync to joining clients; `/reload` leaves them unchanged. A higher-priority file replaces the whole group. An omitted key uses its code default, which equals the shipped value. Each registry validates all its groups before publishing any value: a missing group, an undeclared group or key, or an invalid value stops the world from loading.
