Unity: missing JSON fields keep initializer/constructor values on FromJson, and FormerlySerializedAs preserves renamed fields; Godot: ConfigFile drops comments on save and the saving tutorial gives no format versioning or migration guidance, so versioning must be added by the game.

Unity: missing JSON fields keep initializer/constructor values on FromJson, and FormerlySerializedAs preserves renamed fields; Godot: ConfigFile drops comments on save and the saving tutorial gives no format versioning or migration guidance, so versioning must be added by the game. Curator qualifications: Documentation read 2026-10-22; no code compiled or run; no saves synced. Godot negative is a bounded text search of one tutorial page. Limitations: Documentation read 2026-10-22; no code compiled or run; no saves synced. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
