The old bash script configured itself through `GITTALLY_*` environment
variables. The blanket rename rewrote those literals, so the converter
was looking for `WERKATOR_*` — a spelling no host has ever written. Fed
a real legacy file it would have found nothing and written an almost
empty configuration, without an error, which is the same silent failure
this rename is otherwise careful to avoid.
The conversion has served its purpose with the vm2176 to vm4006
migration, so it goes instead of being repaired. What remains is the
setup of a new instance: the preconditions, the credential prompt, and
the machine configuration written mode 600 — now carrying the host's
public URL as well, since that is host-specific too. Everything the
repository builds comes from `init` and its templates.
It also stops emitting a legacy `branches:` section, which step 18 is
about to reject outright.
`docs/plan/00-legacy-analysis.md` and `13-nginx-tls.md` get the real
`GITTALLY_*` spelling back: they record what the old script read.
