// The four TS-family tables of a `refs`/`read` answer's `inbound` or
// `outbound` object, split out of `json.rs` to keep that file under its flat
// line limit. Each joins the object after every older key, and only when its
// own total is non-zero -- the rule `implements`/`overrides` follow -- so an
// answer with no TS edge keeps the exact bytes it had before these existed.
