Spatial Chunk Management Engine (SCME)

[2.0.0-beta.1]

Added • In-world 3D arena borders with 7 styles (World Border, Hex Shield, Plain Colored Barrier, Pillars, Hybrid, Barrier Icons, Off). • Horizontal ceiling and floor caps with independent per-surface proximity fading. • Global and per-structure customization for border style, RGB color, opacity (10%-100%), and warning distance. • Configurable vertical scale sliders (Ceiling/Sky Height 0-128, Vertical Leave Distance 4-64) across all structures. • Live in-world vertical bounds updating on config save without requiring arena re-entry. • Automatic migration of legacy vertical values in configuration files. • Structure profiles for Bosses' Rise (sandworm_nest, dragon_tower, underworld_arena, yeti_hideout, kraken_ship in BOSS_ONLY mode). • Structure profiles for Twilight Forest hollow trees and Vanilla desert pyramid. • Expanded debug telemetry with raw structure heights and exit bounds in F8 snapshots and /scme debug overlay.

Changed • Skor Yeti Hideout: expanded default horizontal leave distance to 8 chunks (128 blocks) and vertical bounds to vEnter=8, vExit=28, sky=32. • Frostmaw Lair: set default footprint to 5 chunks radius circle with vEnter=8, vExit=28, sky=32, expanding bounds to match loaded radius. • Hydra Lair: calibrated default footprint to Auto-Fit with 3 chunks (48 blocks) leave distance and HYBRID border style. • Increased default sky headroom and vertical exit buffers for surface, mountain, and aerial structures.

Fixed • Fixed singleplayer chunk streaming freeze by filtering ready chunks before distance sorting in PlayerChunkSenderMixin. • Preserved loaded client chunks when transitioning into or out of arena locks to prevent visual reload stutter. • Bounded boss detection to 3D vertical bounds and added structure-to-boss matching to prevent underground false positives. • Excluded non-boss summons, projectiles, and multi-part entities from Bosses' Rise detection, and added isDying() checks. • Fixed rectangular border corner seams and moved border rendering to AFTER_WEATHER in front of clouds.
