+ * Arbeitszeitnachweis next to the hours actually worked.
+ *
+ * Hand-trimmed, like Version20260921122743: doctrine:migrations:diff sweeps in the
+ * long-standing datetime and JSON drift of the dev database, none of which belongs here.
+ *
+ * The per-day start, end and break times that go with these live in the existing "days" JSON
+ * column, so they need no schema change. Rows imported before this migration simply carry
+ * neither, and are refreshed by the next import of a month that is not yet signed.
