Employees from outside the EU, the EEA and Switzerland need a residence permit, and HR needs to know when it expires — about eighty people in the current data, across Türkei, Serbien and Bosnien. Two columns, the same shape as the dismissal protection: a flag and a date that only means anything with it. The date is optional, because an open-ended permit has none and a mandatory field would force an invented one. The nationality coupling deliberately stays out of the database. Putting it there would mean keeping the country list in two places — SQL and lib/countries.ts, where the picker needs it anyway — so an EU accession would become a migration instead of a line in a list. Worse, correcting somebody's nationality would fail the constraint while the old permit was still attached, which is exactly the moment someone is fixing a mistake. The UI decides whether the fields appear, and clears them when the nationality moves into the free-movement area. So the list is the load-bearing part, and it is tested: 31 entries, all of them values the picker can actually produce, no duplicates, no third countries. A missing nationality reads as "no permit required" — an unanswered question is a reason to record it, not to demand papers. The permit shows on the Stammdaten tab only for the nationalities it applies to. A line reading "Aufenthaltstitel: Nein" under an Austrian citizenship would look like information rather than a question that does not arise. Filter by it and by when it expires — the question behind that being "whose permit runs out next quarter" — plus columns in the export. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
