Amplitude, frequency, seed, rotational amplitude and the decay rate are authored configuration and are always written (rotational amplitude is omitted when it is the zero default, so a position-only shake stays a small document). Trauma is scene state — a camera saved mid-impulse is still shaking, and nothing else can reconstruct the envelope — so it is written the way CHARACTER_CONTROLLER_SERIALIZER writes verticalVelocity. skippedSteps is a diagnostic of a run and is not carried.

The seed is the hash salt, not a live SeededRandom stream: the noise is a pure function of (seed, simulationTime) and there is no stream position to restore.
