// FrSkyData::clear() is a hand-written field-by-field reset (not a memset),
// so any field it forgets is left uninitialised. varioCenterSilent and
// ignoreSensorIds were both omitted yet are serialised to YAML, which made a
// freshly-cleared model emit non-deterministic values (e.g. centerSilent
// emitted as a stray byte, then masked to 0/1 on reload -> non-idempotent
// round-trip).
//
// Poison the storage first so the test fails deterministically if clear()
// ever stops initialising one of these fields.
