📜 Vein Miner 3D — Release v1.0.0 (MC 26.1 – 26.3)

🚀 Major Highlights

• Full 1.21+ / 26.1–26.3 Standardization: Upgraded to strict modern datapack standards featuring the singular function directory nomenclature, strict lowercase namespaces, and mandatory min_format (101) & max_format (121) requirements.
• 26.3 Snapshot Overlay Support: Built-in dynamic overlay_26_3 (formats 111–121) that automatically adapts predicate and item modifier syntax (type field update) for seamless forward compatibility.
• First-Join Setup GUI: Integrated an automated first-join configuration menu triggered via vm.joined and player ID tracking. Offers 6 clickable chat buttons (Hold Sneak, Always Active, ON, OFF, Status, Help) with updated hover and click event formats.
• Dual Activation Engine:
  
  
  • Hold Sneak (Mode 0): Triggers vein mining strictly while crouching.
  • Always Active (Mode 1): Triggers automatically on ore mining without needing to crouch.

⚙️ Engine Improvements & Fixes

• Safe Load Initialization (load.mcfunction): Preserves custom player and server configuration settings upon running /reload. Registers 19 vanilla ore stats, 7 dummy objectives, 5 trigger objectives, and cleans up active markers.
• Hardened Vein Clamping: Applied a strict 64-block safety clamp during every vein mining check to prevent server performance degradation and runaways.
• Full Tool Tier System: Added comprehensive support for all 7 pickaxe tiers (Wooden, Stone, Iron, Gold, Copper, Diamond, Netherite) with accurate tool durability loss, durability checks, and XP drop calculations.
• Orthogonal 3D Chain Engine: Implemented precise 6-sided face-to-face recursive marker scanning for continuous ore vein extraction.

🌐 Compatibility
