🚂 Railway Evolution v1.0.5 — [THE ECOSYSTEM & INTERSECTION OVERHAUL]

This update marks a significant architectural milestone, transforming Railway Evolution from an AI-train controller into a full-scale Traffic Ecosystem. By introducing the Event-Driven Perception Engine and Player-Train integration, we have achieved seamless traffic management where AI and players exist in the same environment.

✨ Key Features of v1.0.5:

• Ecosystem V2: A unified, event-driven perception engine allows AI to perceive player-controlled trains as dynamic traffic participants rather than obstacles.
• Flow Follower (Convoy Mode): AI trains now intelligently match the speed of the lead vehicle (player or AI), allowing for fluid, real-world traffic patterns without constant emergency braking.
• Deterministic Junction Priority: Replaced the legacy "first-come-first-served" logic with a distance-based "steal" mechanism, ensuring the closest train always has the right-of-way.
• Zero-Allocation Architecture: Massive backend refactor using VarHandle and object pools, resulting in near-zero GC pressure during high-traffic ticks.

🛠 Technical Changelog (v1.0.5):

Perception & Ecosystem

• PerceptionEngine: New event-driven scanner using swept Bezier-sampling for precise curved track awareness.
• EcosystemRegistry: Centralized real-time registry for all entities (AI + Player-controlled).
• PlayerTrainHandle: Dedicated adapter that enables player-driven trains to be registered in the VBS and traffic registries.
• FSM v2: Implemented a new multi-layered State Machine with Layer 1 (Player) → Layer 0 (Safety) authority model.

Intersection Logic

• JunctionReservationManager: Added distance-based stealing logic—trains now "steal" reservations if they are significantly closer (>3 blocks) to the intersection.
• Ghost Pass Logic: Trains yielding at an intersection now designate the winner, allowing the winner to perform a "ghost pass" through the yielding train.

Collision & Proximity Fixes

• Lateral Tolerance Optimization: Reduced lateral scanning distance from 8 to 3.5 blocks, eliminating phantom braking on parallel tracks.
• Omni-Zone Refinement: Omnidirectional detection range reduced from 8 to 5 blocks with strict isOnSameTrack() filtering.
• BFS Filtering: Fixed flickering where physical scans conflicted with BFS results; physical scans now only override BFS if a threat is 4+ blocks closer.
• Player Detection: Expanded detection radius for player-controlled trains to 20 blocks, bypassing strict graph-data filters to ensure the AI never loses sight of the player.

Refactor & Performance

• VarHandle Integration: Replaced reflective Field.get() calls with VarHandle for 5–10x faster primitive access.
• State Machine Cleanup: Removed conflicting forceStop() triggers from old state logic; unified FSM v2 as the primary authority.

🔮 Future Roadmap: Long-Term Support

With the v1.0.5 architecture now stabilized and fully modularized via the Adapter pattern, Railway Evolution enters a phase of long-term stable support. My primary focus is now maintaining this high-performance core across multiple versions of Minecraft and Create, ensuring your rail networks remain reliable for years to come. I am committed to deep, consistent maintenance to keep this project the gold standard for rail automation.
