/**
 * The Plane-2 code NAMES — the ONLY list of domain-error slugs (ggui#880).
 *
 * The registry rows (`./domain-error-codes`) carry each code's tools,
 * recovery, emitter and description, and are typed exhaustively over this
 * tuple: a name without a row, or a row without a name, does not compile.
 * The names live apart from that prose because a reader of the wire grammar
 * needs only them. `parseDomainErrorText` (`../errors/domain-error-text`)
 * imports this module and nothing else, so a browser that parses a domain
 * error (`@ggui-ai/protocol/wire`) does not carry every row's text.
 *
 * Disjoint from the refusal registry (`./refusal-codes`, pinned): one code
 * names one plane.
