translation.sources_invalid: A translations folder's sources record cannot be read

A translations folder's sources record cannot be read.

Area 10, Configuration; not declinable; the next step is usually the agent's.

The record in a translations/ folder says which wording each translation was made from and who accepted it. Jadpo writes it, and a stale or unaccepted translation is judged from it, so a file Jadpo can't read hides both.

example

// Generated by Jadpo from this folder's translations; update it with `jadpo translations update`, never by hand.record translations 1translation de_de.hello was made from Hello, {name}.

jadpo checkcheck failed: 1 error, 4 files

error domains/greeting/translations/sources.jadpo_record can't be read: this line is not a translation entry

--> domains/greeting/translations/sources.jadpo_record:4:1

  |4 | translation de_de.hello was made from Hello, {name}.  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this line is not a translation entry

reason: This file records which wording each translation was made from and who accepted it. Jadpo writes it, and a stale or unaccepted translation is judged from it, so a file it can't read hides both.
next: Run jadpo translations update, which writes it again (agent)
