`t()` answers a missing key with the key, so "does this code have a
sentence" was a comparison written inline at every site that wanted a
code's sentence or a fallback, twenty-odd times in several spellings.
translateOrNull, translateCodeOrNull and translateCode in
src/lib/i18n/translate-code.ts now hold that probe, every site uses
them, and a guard refuses the inline comparison anywhere else.
The guardian's read of a managed record's connections now carries the same
server-resolved health the owner's own envelope does, loaded for the record
and never for the guardian. The legacy state stays on the wire for one
transition release.
