1//! **What a sold private Gunnar is called** — ONE function, called by the shop
2//! that sells it (monetize's estate order: the ready mail's first-login link,
3//! the DNS records, `laid.json`'s `names`) and by the kit that installs it
4//! (its certificate, its passkeys' relying party, its DNS records).
5//!
6//! A sold estate lives under the SELLING shop's apex (owner, 2026-10-08):
7//! gunnar.rs sells `acme.gunnar.rs`; test2's shop sells `acme.test2.gunnar.rs`
8//! — the certificate, the passkey RP, the DNS, the link, the mail and
9//! `laid.json` all say the same name. Wiring trace A43: monetize named it
10//! `<co>.<apex>` while the kit named it `<co>.gunnar.rs` whatever the apex, so
11//! a test2 buyer's first-login link led to a name nothing served.
