- Case numbers SUP-000001, SUP-000002 … per customer, unique per customer (new index; a migration step renames any old duplicates first). The portal suggests the next number on the finding page and under the new "Ny sag" on the customer page; an empty field gets the next number, a typed one that is taken is refused. Concurrent creates retry. - SupportCase gains Source (Staff/Customer), description, contact name, e-mail, phone, the customer's Windows user and ClientRequestId. - POST/GET /api/v1/cases for the customer's agent (license with priority support): creates a case idempotently on ClientRequestId, links the finding it came from, lists the customer's cases incl. staff-created. Customer/license creation is shared with the findings endpoint. - Optional mail to support for customer cases (MailKit; prefers AUTH LOGIN as Microsoft 365 needs). A failed mail is logged, never fails the call. deploy-hub.yml writes optional SUPPORT_SMTP_* secrets to .env. - Supportrapport: created, closed, open now, average/median resolution time, oldest open case and customer-created share per customer for a period (default 90 days), plus the cases; CSV for Danish Excel. - Cases page: newest first, customer cases marked, contact/description. - Customer page: findings can be filtered to one instance (?instans=id, ignored for another customer's instance); active findings per instance by severity. - dotnet-ef as a local tool (dotnet-tools.json) for the migration.
