NEVER Do (Expert Anti-Patterns)

NEVER allow pathfinding "Jitter" when moving group units; strictly stagger path queries and enable RVO Avoidance only when units are in motion to save CPU cycles.
NEVER update RVO avoidance every frame for all units; strictly use Avoidance Threading (Project Settings) and replace static units with NavigationObstacle.
NEVER let units get stuck in infinite path loops; strictly implement a timeout and IDLE state if a destination is unreachable.
NEVER use _process() on hundreds of individual units; strictly use a central UnitManager or _physics_process only when required.
NEVER calculate unit visibility manually for Fog of War; strictly use a Shader-based mask (SubViewport + ColorRect) for GPU efficiency.
NEVER process unit AI or pathfinding synchronously for mass groups; strictly offload to WorkerThreadPool and stagger path updates.
NEVER use high-poly visual meshes as NavMesh source geometry; strictly use simplified Collision Shapes for baking.

NEVER forget Command Queuing (Shift-Click); strictly store an Array[Command] and implement a "Force Move/Attack" bypass.
NEVER create excessive micromanagement; strictly automate low-level tasks like auto-aggro range and auto-return for resource gathering.
NEVER use exact floating-point equality (==) for grid or timers; strictly use is_equal_approx() for deterministic triggers.
NEVER rely on the visual SceneTree for selection data; strictly maintain a Typed Selection Set of RefCounted or Resource objects for deterministic serialization and netcode.
NEVER forget Command Queuing; strictly implement a Command Pattern using serializable Dictionary or JSON states for save-game and multiplayer playback.
NEVER forget to duplicate_deep() globally shared Resources; otherwise, modifying one unit's data (e.g., stats) affects all.
