Overview

The exact string this registry emits for an unregistered name, taken from the TLD definition.

This is the curated, high-confidence signal — "No match for" for Verisign, "Domain not found" for PIR — and the obvious design would check it first, before anything else.

Here it runs after the rules that establish a registration, and that reordering fixes a real failure mode: when a TLD is mapped to the wrong server, or a registry starts returning a record that happens to contain the marker text, checking the marker first turns a registered domain into an available one. Letting a genuine record win first costs nothing, because a response cannot both be a record and be the registry's not-found message.
