Phase 1: you submit an application

What happens here

Your application goes through the same processing as any other incoming case: seal, working copy, extract, prove, decide, notify. This page attaches the deployment's own token on the server; the raw endpoint POST /ingest stays closed with a 403 for direct callers.

Every applicant on this page is invented. The names, dates of birth, insurance numbers and addresses were constructed for this demonstration and belong to nobody.

What you can try

Go ahead and change things. Each of the changes below makes the system do something DIFFERENT, and something real - and the next step shows you exactly what.

Delete the insurance number
Empty the text box. The completeness check reports a gap, the case lands on tier 2, and a request for information is prepared carrying exactly the sentence the procedure configuration provides for it.
Make the date of birth implausible
Pick 1 January 1902 in the calendar. The insurance number carries the date of birth in positions 3 to 8 and no longer matches it: the cross-field check fires, without anything being unsealed.
Push the start of the activity far into the future
Pick 1 January 2035. The calendar bounds in the procedure configuration deliberately do not catch that - it is the shadow scorer's job, and it flags the case and names its reason in plain words.
Empty the client
On the applications that carry a channel hint this opens a gap and prepares a request for information asking for exactly that detail. With Frau Musterfrau, whose procedure is derived from the content, the derivation loses one of its two supports - the client and the activity are read together there.
Empty the given name
The surname goes through on its own. Both boxes write to the same place in the submission; the page joins them before anything is sealed, and an empty box is left out rather than sent as a space.

Edit the form and submit

What Beate Schliebermann submitted

Every field already filled in here is required: empty one and hit submit, and your browser marks it red and sends nothing. The exceptions are the three fields the suggestions above the form ask you to delete - insurance number, client and given name - because otherwise this page would recommend something it blocks itself. That check runs in the browser and without JavaScript; the system's own completeness check comes afterwards and separately from it.

Enclosures (PDF, simulated)

Choose what the applicant encloses. The documents are prepared and synthetic; their names are the ones the German pension insurance really asks for these papers under. A ticked document becomes a real attachment on the submission: it is sealed, gets a text layer and goes through the same processing as the form. The next step shows you the working copy of each document.

C0031-beschreibung-des-auftragsverhaeltnisses.pdf The annex without which, in form V0027's own words, no determination of employment status can be made.
einzelvertrag-und-projektbeschreibung.pdf V0027, item 16 asks for all individual contracts, project descriptions and task descriptions.
rechnungen-in-kopie.pdf Asked for twice (V0027 item 3.2 and C0031 item 3.1): without them the employment status cannot be decided.

There is deliberately no way to upload a file of your own here. An upload control on a public demo would be an ingest path around the redaction boundary, and that boundary is what this whole system is about. The documents above belong to the fictional applicant you picked and to nobody.
