Laminar Engine - Version 1.3.0 "Echo Extended" Changelog

This major release introduces a complete overhaul of the audio occlusion pipeline (Project Echo), implements high-fidelity hardware-accelerated environmental acoustics, resolves critical transition states in AI tracking, and introduces a modern hardware diagnostic overlay.

1. Project Echo: "Extended" (High-Fidelity Audio Occlusion & Reverb)

• Dual-Engine Hybrid Acoustics: Implemented native hardware-accelerated OpenAL EFX support. On compatible devices, the engine now delegates acoustic calculations directly to the audio hardware, applying physical direct filters (low-pass high-frequency damping based on block obstruction) and dynamic environmental reverb (decay times mapped to physical room volumes).
• Laminar Ghost Echo Fallback: Engineered a robust, software-side fallback system for systems lacking EFX support. It utilizes a dynamic, asynchronous "Ghost Sound" spawner that schedules identical duplicate sound instances with physical delays, muffled volumes, and adjusted pitches to simulate cave echoes without any native OpenAL crash risks.
• Open Sky Reflection Guard: Optimized the Fibonacci sphere raymarching kernel to detect open space. Rays that escape the voxel grid boundaries without hitting solid walls contribute 0% to the reverb calculations, completely eliminating artificial reverb in open plains or under the sky while keeping cave acoustics rich and deep.
• Decoupled Render Thread (Zero Memory Stalls): Introduced a CPU-side RAM cache for all active sound calculations. The client rendering thread now queries standard, L1/L2 cached memory arrays instead of reading from un-cached mapped GPU memory, completely resolving physical memory bus stalls and stabilizing frame-time 1% lows.
• Dynamic Range & Mod Compatibility: Replaced static range tables with dynamic queries utilizing the game's native attenuation properties and volume scales. Any custom music discs, instruments, or sound events introduced by other mods are now automatically and correctly occluded and propagated.
• Queue Congestion Prevention: Implemented distance-based sound prioritization, capping active OpenCL audio calculations to the 32 closest sound sources per cycle to minimize driver-level submission overhead.

2. Project Hive (Asynchronous AI Pathfinding)

• Resolved Creative Transition Loop: Patched a critical logical loop where switching game modes to Creative or Spectator caused the GPU-driven grids to endlessly flicker (toggling between 0 and 1).
• Resolved Lingering Mobs Bug: Fixed an issue where out-of-radius mobs were missed by the cleanup sweep, keeping the active AI tracker occupied. All tracking registries are now fully and permanently flushed upon player invulnerability or game-mode change.

3. Hardware Diagnostic OSD (F3 Debug Screen)

• Modern Rendering Hook: Successfully bypassed deprecated debug screen methods. Injected a lightweight, zero-refmap target hook directly into Minecraft's modern, monolithic line-extraction pipeline.
• Real-time Performance Telemetry: Displays the locked hardware co-processor GPU name, active EFX status, active sound channels, and active pathfinding grids/mobs directly in the F3 screen under the system information panel.
