1. Production Architecture: Temporal Fact Superseding (`valid_from` / `valid_until`) & Cosine-Similarity Deduplication
def supersede_conflicting_memory(existing_fact: dict, new_value: str, timestamp_iso: str) -> tuple[dict, dict]:
archived = {**existing_fact, "valid_until": timestamp_iso, "is_active": False}
current = {**existing_fact, "object_value": new_value, "valid_from": timestamp_iso, "valid_until": None, "is_active": True}
return archived, current
