  "description": "A reference to a game by its BoardGameGeek id, PLUS a minimal denormalized snapshot of the game's name (and optionally year) captured at write time. The BGG id is rolld's permanent identity key (used for aggregation, the canonical URL, the rating rkey). The 'name' snapshot makes the record SELF-DESCRIBING: it stays human-meaningful even if BGG disappears, the hydration Worker is down, or a future AppView has never heard of BGG. The snapshot is 'what the user called the game when they logged it', not authoritative live metadata — current cover/weight/rating are still hydrated at display time via resolveGame(). This is the decentralization safeguard (see DECISIONS D-7, D-32): the id is for aggregation, the name is for durable meaning. Object (not bare string) also leaves room to add optional fields later (e.g. a 'catalog' discriminator) without a breaking change."
