Save & Persistence

Build the save system of a game. References: Skyrim's changeform deltas, BotW's revival flags, Dark Souls' continuous journaling, Genshin's server-authoritative state, and the MMO backends (EVE, WoW, Albion). This skill fills the world-state store referenced by open-world-streaming/enemy-ai-framework/minimap-worldmap, the settings split referenced by menu-ui-manager, and the CanSave gate of scene-flow-manager.

The architecture rule

The save is a versioned store decoupled from runtime objects. Systems write deltas keyed by stable IDs; the store is the single source of truth; runtime state is a projection rebuilt from base game data + save deltas on load. Never serialize live scene objects.
