Godot 4.7 Baseline

• Expert patterns in this skill target Godot 4.7+ (stable, 2026-06-18).
• Consult the Godot 4.7 migration guide when upgrading projects from 4.6.
• NEVER assume 4.6 defaults (stretch mode, audio area_mask, RichTextLabel percent flags) without checking 4.7 migration notes.

NEVER Do (Expert Anti-Patterns)

Generation & RNG

• NEVER make runs dependent on pure RNG; strictly provide mitigation (rerolls, shops, pity timers) to ensure every run is winnable.
• NEVER use unseeded RNG for world generation; strictly initialize isolated RandomNumberGenerator with a predictable seed for daily runs/debugging.
• NEVER rely on @GlobalScope.randi() for critical logic; strictly use local RNG instances to prevent global state pollution.
• NEVER use Array.pick_random() for critical content drops; strictly use a Shuffle Bag to prevent statistically unfair streaks.
• NEVER generate massive dungeons on the main thread; strictly use WorkerThreadPool.add_task() or add_group_task() to distribute generation across cores and prevent frame freezes.
• NEVER interact with the SceneTree from a background thread; strictly generate dungeon data in a thread-safe Array/PackedByteArray before parsing on the main thread.
