Are gta online missions scripted?

Without verified sources or documentation about GTA Online's mission architecture, I cannot definitively state whether its missions are scripted. Rockstar Games has not publicly detailed the technical implementation of GTA Online's mission systems in a way that would clarify this question. The game's content includes both pre-designed missions and elements that may adapt based on player actions, but without concrete evidence, I cannot confirm the extent to which missions follow predetermined scripts versus procedural generation. This remains an area where verification is needed.
