Remove Supabase
The database moved to a container of our own; the platform is gone. This takes out what was left of it — and, where the leftovers were load bearing, moves rather than deletes. Moved, not deleted: supabase/migrations/ -> db/migrations/ the schema's source of truth supabase/build-org.ts -> scripts/build-org.ts lib/supabase/types.ts -> lib/types.ts 52 import sites repointed The bookkeeping needed care. It lived in `supabase_migrations.schema_migrations`, and simply renaming the schema would have left the runner facing an empty table: it would have called all 67 migrations pending and replayed them against a database that is long since current. So the runner now creates `migrationen.schema_migrations` and, once, copies the old rows across — guarded so a second run does nothing and a fresh database skips it entirely. Only then does migration 20260907100000 drop the old schema. Deleted: the CLI config, the seed, the historical schema/function dumps (nothing read them), scripts/umzug-von-supabase.sh (the move is done), and both Supabase packages plus the CLI. Nothing in the application imported them — the build now succeeds with no environment variables at all, which is the proof. Integration tests: six of them signed in through Supabase Auth and asserted against the anon key and the service role. That model is gone, so the tests were not portable — they are deleted. session-context and employee-status-filter already ran on pg and are untouched; om-reporting is ported to a direct connection because it guards a real risk (the reporting line rule exists twice, once in SQL and once in TypeScript). CI: the integration job started a Supabase stack. It now runs a postgres service, applies deploy/db-init and every migration to an empty database — that was the valuable part, and it still holds — then checks that a second run is a no-op, which is what proves the bookkeeping works. Docs: security-review.md audited a service-role key, a cookie adapter and auth.users, none of which exist. Restating findings about removed components would suggest today's system had been reviewed; it has not. It now records what was removed and says a fresh review is due. data-model.md was already marked obsolete and described the pre-OM schema; azure-migration.md was a plan for a route not taken. Both deleted. Verified: npm ci, typecheck, lint, 445 tests, build — all clean without the packages. Integration tests skip cleanly with no database. Migration SQL and the runner are reviewed but NOT executed: no Docker here, and the old instance no longer resolves. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

-- Organisationsmanagement nach SAP-OM-Vorbild.
|
||||
--
|
||||
-- Bisher: drei feste Tabellen (divisions -> departments -> teams) und
|
||||
-- Personen, die direkt daran hängen (employees.division_id/team_id) mit
|
||||
-- einer frei gepflegten manager_id. Damit ist die Hierarchie in ihrer Tiefe
|
||||
-- fest verdrahtet — eine Abteilungsleitung liess sich nicht abbilden, ohne
|
||||
-- das Schema zu ändern, und ein Team direkt unter einem Bereich gar nicht.
|
||||
--
|
||||
-- SAP OM löst das über wenige Objekttypen und Verknüpfungen dazwischen:
|
||||
--
|
||||
-- O Organisationseinheit org_units (rekursiv über parent_id)
|
||||
-- C Stelle / Job jobs (Katalog)
|
||||
-- S Planstelle positions (gehört zu genau einer O)
|
||||
-- P Person employees (besetzt eine S)
|
||||
--
|
||||
-- A003 "gehört zu" positions.org_unit_id
|
||||
-- A012 "ist Leiter von" positions.is_chief
|
||||
-- A008 "Inhaber ist" position_assignments
|
||||
--
|
||||
-- Die Berichtslinie wird daraus abgeleitet statt gepflegt, siehe die
|
||||
-- folgende Migration. Ebenen sind nur noch ein Etikett (unit_type), keine
|
||||
-- Struktur — eine fünfte Ebene ist damit eine Datenfrage, keine Migration.
