// int64in: 64-bit integer input.
// CA limitation: served as DBR_DOUBLE over Channel Access (f64, precision loss for |val|>2^53).
// Native i64 storage is lossless; precision is only lost at the CA wire boundary.
//
// Alarm threshold fields (HIHI/HIGH/LOW/LOLO/HHSV/HSV/LSV/LLSV) are intentionally absent
// from the field list so they route to RecordInstance::common.analog_alarm via
// put_common_field, matching the path used by longin/ao/ai.
