Accepting an invitation with a roomId previously only set User.roomId
— no Contract row was created. Since every tenant-facing feature
(Miet-Ampel, Vertragsdokumente, Kündigungsfristen, ...) is driven by
Contract, not User.roomId, the tenant would silently show up nowhere
despite "having" a room. Now the accept transaction also creates an
active Contract (rent/deposit defaulted from the room's baseRent/
utilityPauschal, same defaults already used by the "Wieder aufnehmen"
flow) and marks the room OCCUPIED, unless the room already has an
active contract (guards against a stale/duplicate invite race).
Accepting an invitation as a TENANT now mandates phone number, current
first-residence address (Erstwohnsitz), and both sides of an ID
document — the accept endpoint rejects the request with a clear error
if any are missing. A Schufa credit report upload stays optional, but
if provided its issue date must be within the last 3 months or the
request is rejected.
New User fields: phoneNumber was already there; added
firstResidenceAddress, idDocumentFrontUrl, idDocumentBackUrl,
schufaDocumentUrl, schufaDocumentDate. Kept nullable at the DB level
(existing accounts have none of this and shouldn't be broken) —
enforcement lives in the accept-invitation route, not a DB constraint.
Landlords now see a completeness badge ("Profil vollständig" /
"Unvollständig: X fehlt") plus a Schufa freshness badge on each
contract card in Verträge & Abrechnung, with direct download links for
the uploaded ID/Schufa files.
