Diagnosis — 2026-09-22

1. The control plane collects every placed machine's name and address for a resolution keyed by the internal name (homer.internal), because that is the map every container is given as its hosts. The facts that render the hosts file and the resolver's zones took the same map as bare names and appended .internal to each — their unit tests fed them bare names and passed.
2. Fixed in the facts: a name is read as either form, and each machine is written once as <machine>.internal with its bare name beside it. A test feeds both keyings and holds the files equal, and holds the zones free of a doubled suffix.

Located in: the facts. Not a decision. Proven by the unit test and by the large mesh bed's name tests, once its controller image is rebuilt from the fix.
