Random Page policy test — 1.0.1.137-beta.1

Install the new JAR and launch once so the new entries appear in Minecraft's config/rivencraft-local.toml. Close the instance before editing. On a dedicated server edit its own config, not the client's.

For a visible check, replace only the existing random_pages section with:

[random_pages]
allowlist = ["terrain/flat", "biome/single", "biome/plains", "sky/static", "lighting/normal", "weather/off", "feature/not_present"]
blocklist = ["sky/nether", "celestial/sun", "celestial/moon"]

The deliberately nonexistent feature entry restricts only optional features, leaving an empty feature pool for this test.

1. Bind a Descriptive Book with only a Link Panel. Enter it: expect Flat terrain, Plains, Static Sky, normal lighting, no rain and no suns/moons. Optional Page features/structures should be absent; native biome decoration is independent.
2. Bind an authored Flat/Plains/Single/Nether Sky book. Nether Sky remains usable despite the blocklist; the setting controls random generation and direct library loot, not manual authorship. The Page remains visible in Creative/JEI.
3. Change sky/static to sky/end, restart and revisit the first Age. It must retain Static Sky. A newly bound Link-Panel-only book should get End Sky.
4. Optional library check: allowlist = ["sky/static"], blocklist = ["sky/nether"]. New library direct Pages may include Static Sky or other unrestricted categories, but never another Sky Page. Test both library loot modes where desired. Existing chests/stands remain untouched; AGE_ONLY may have no Pages when the book's written Page set has no eligible entries.

Restore both lists to [] afterward unless you want the restrictions to persist. No existing Age should change. Keep the full world backup customary for beta updates. Native biome presets and required minimum-biome fallbacks intentionally bypass biome-Page filters; Sealed Notebooks keep their separate 1.21.1 draw pool.
