NsTut Endless

Endless 0.5

• Added a configurable sparse logical build envelope from Y=-8,000,000 through Y=7,999,999.
• Made config/endless.json authoritative for placement, vanilla commands, teleport validity, AI limits and sparse runtime bounds; the ±8M representation ceiling is no longer treated as automatically buildable.
• Preserved valid million-scale configuration values across launch instead of clamping them to the old ±2032 dense envelope.
• Kept fresh v0.5 worlds on a vanilla [-64,320) dense chunk core regardless of logical range, so widening the config does not widen LevelChunkSection[].
• Preserved wider historical dense cores for upgraded worlds only when required for legacy Anvil safety; that internal range never widens the current configured build limit.
• Fixed same-JVM high-Y save/rejoin corruption so legacy/wide dense chunks and normal generated terrain remain intact when sparse million-height data is saved, the world is closed, and the same save is reopened.
• Added dedicated compressed-NBT sparse page persistence outside vanilla Anvil section serialization.
• Added an extended BlockPos network encoding for high-Y positions while preserving vanilla encoding in the normal range.
• Added high-Y block, fluid and block-entity access through normal Level/LevelChunk APIs.
• Added sparse heightmap overlays for world-surface, ocean-floor and motion-blocking queries.
• Added sparse block/sky lighting that avoids vanilla packed-Y wrapping.
• Added sparse high-Y POI persistence and search without widening vanilla SectionStorage loops.
• Routed high-Y block updates around ChunkHolder's dense per-section batching.
• Preserved client block prediction above vanilla's packed BlockPos Y envelope.
• Kept SectionPos-keyed POI/tick addressing inside the signed 20-bit SectionPos Y representation envelope.
• Added a 512-block camera-following render/sync window with sparse page resync and unload eviction.
• Added server-authoritative logical + dense-height negotiation for Fabric and Forge clients.
• Added explicit Waystones 1.20.1 placement compatibility so its Level#getHeight() ceiling follows the configured logical maximum.
• Added real Waystones+Balm compatibility coverage for sparse high-Y placement, block entities, manager position/UUID state and client observation.
• Added real /setblock live coverage proving min and max-1 succeed while min-1 and max are rejected on both loaders.
• Split client-only loader bootstraps so dedicated servers never resolve client classes.
• Expanded the real-client sparse-edge scenario to cover block/fluid/block-entity/POI/light/height persistence, rendering and player travel on both Fabric and Forge.
• Retained v0.4 fail-closed legacy-world migration guarantees.
