World Dimension Loader (WDL) imports COPIES of existing worlds as configurable Dimensions on Minecraft 1.20.1 Forge and connects them through custom Gates.

Main features:
- simple ID-centered world import configuration;
- LIST/ALL Gates with configurable frames, sizes, Igniters, costs and cooldowns;
- per-Dimension Environment, Respawn, Bed, Anchor, Return Scroll and Inventory/Travel policies;
- Timed Sessions with safe Forced Exit;
- fixed physical Dimension IDs for newly initialized runtimes when Reset is disabled;
- timestamp Generation Rotation when Runtime Reset is enabled;
- safe cleanup through Startup GC;
- fail-closed protection when runtime authority is ambiguous;
- cleaner Reset diagnostics: routine waits are DEFERRED while terminal safety stops remain BLOCKED errors;
- Japanese and English in-game text and documentation.

In 1.4.0, a newly initialized runtime with reset_on_empty=false uses wdl:<id> as its fixed physical ID. Existing 1.3.0 timestamp runtimes are preserved in place and are not reverse-migrated automatically. Do not manually rename or move WDL runtime folders.

Reset is optional and can discard runtime changes because fresh generations are rebuilt from the imported source copy. Safe cleanup can temporarily use substantial disk space until restart.

Valkyrien Skies and Distant Horizons are not required. Current compatibility work was validated around Valkyrien Skies 2.4.11 and Distant Horizons 3.2.0-b behavior. Unknown future versions are not guaranteed.
