Function render_row_values 

pub fn render_row_values(v: Value) -> Value

§1.4 rows as values (1.2): a store row that surfaces as a VALUE in a result tree — a nested collect { } / first { } / single { } with an empty projection, or a values item that is a row — renders as { id, path } (the target’s id column as a string; the owning document’s path: a docs row’s path, every other row’s __path join column), never the store row. Everything else recurses, dropping the hidden tag as strip_tags.
