const UNSERVED_ROWS: [&str; 18];Expand description
Top-level rows the read does not serve, of two kinds: the transcript’s own bookkeeping, which the CLI writes to disk and never streams, and the wire types that live only on the stream and have no durable row.
A row not named here is an unknown type, and draws as itself. These are the types the read has always dropped, so keeping one would change what a reopened conversation holds rather than restore what a live one drew.
