Local role: One explicit change applied while deriving a successor perceived state from an action projection.

Big-picture role: Audit-friendly delta object that makes projected changes visible instead of hiding them inside the final projected perception only.

Inheritance:

• dataclass

Parameters and fields:

• change_id: str
• change_type: str
• subject_id: Optional[str]
• space_id: Optional[str]
• applied: Optional[bool]
• metadata: dict

Known change_type values:

• state_changes
• resource_consume
• resource_produce
• object_added
• object_removed
• component_added
• component_removed

Methods:

• to_dict() -> dict
• from_dict(data) -> ProjectedPerceptionChange

Notes:

• component_added and component_removed describe projected changes to perceived actor composition, not mutations of the ontological world model.
