// PINS: a singleton cell path read in an INSERT literal's rhs. The cell
// rewrite that lowers `cfg.base` in if/when expressions (690_074) and in
// stored rhs must reach the insert literal too — it is the same read in the
// one remaining write-envelope position. A deserializer meets this shape
// immediately: the pending parsed value sits in a staging singleton and the
// rebuilt row is inserted from it (690_190 detours through an echo tor).
