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)

Economics & Math

• NEVER use standard floats for currency; strictly implement a BigNumber (Mantissa/Exponent) system (e.g., 1.5e300) to prevent INF crashes at 1e308.
• NEVER use Timer nodes for revenue generation; strictly use a manual accumulator in _process(delta) to prevent drift during frame fluctuations.
• NEVER hardcode generator costs or growth; strictly use an exponential formula: Cost = BasePrice * pow(GrowthFactor, OwnedCount) (industry standard 1.15x).
• NEVER evaluate exact float equality (==); strictly use is_equal_approx() or >= to prevent "stuck" progress due to precision loss.
• NEVER parse scientific notation strings with to_int(); strictly use to_float() or a dedicated BigNumber parser.
