b87c8ad64c Remove Supabase
Some checks failed
CI / Lint, Typen, Tests, Build (push) Failing after 5m40s
CI / Migrationen auf leerer Datenbank (push) Has been cancelled
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.

08d2740690 Let planned changes be taken back and corrected too
Deleting and correcting a history entry stopped at the present: anything
not yet effective stayed put. That was not a principle, it was a missing
link. A planned change lives as a payload in pending_org_changes, and
nothing tied it to the history row — only a person and a date, and the
data already holds an Eintritt and a Vertragsänderung sharing one. So
employee_history now carries pending_id, set by change_employee_data
when it schedules something.

One planned change can carry two history rows: Stammdaten and Vertrag
are kept apart but scheduled together. Taking one back therefore strips
only that group's fields from the payload, and cancels the operation
only when nothing is left. Correcting one rewrites its group and the
effective date, and touches no employee data — the change has not
happened yet.

An entry stays on its side of the present. Pulling a planned change into
today, or pushing an effective one into the future, would mean adjusting
the employee record and the pending payload in opposite directions;
that is what the real operations are for.

Existing rows were linked where exactly one running operation matched
the person and date and no other row had claimed it. All five of them
matched. Anything ambiguous would have kept the old refusal, which now
says the actual reason.

The edit dialog surfaced a bug in useDialogFocus that predates it: the
effect depended on the identity of onClose, which almost every caller
rebuilds on render, so it re-ran after each keystroke and its cleanup
pulled focus back to whatever opened the dialog. Any dialog with a text
field would have accepted one character. It never showed because until
now no dialog kept its own state next to its own onClose.

Rehearsed against real data: a two-row planned change corrected, one row
taken back with the operation continuing on the rest, the second taken
back with the operation cancelled, and both refusals.

6297288c13 Let an entry be taken back, along with what it did
HR can now delete a history entry, but only where deleting one is an
honest thing to do — and deleting it also undoes it.

The rule they asked for is the interesting part: the last valid change
wins. Deleting an entry walks its fields one at a time. If a later entry
touched the same field, the current value stays — that later change is
the one in force. Otherwise the field goes back to what the deleted
entry recorded as its "before". So the middle of three entries can be
removed without an old value overwriting a newer one.

Four kinds of entry refuse to be deleted, each saying why in the place
the button would have been. Eintritt anchors the timeline. Transfers,
promotions, absences and exits moved positions and status — they have
proper operations for that, and guessing backwards is how you corrupt an
org chart. Anything not yet effective hangs off a planned change, and
that link is not trustworthy: there is no key between a history row and
its pending row, only a person and a date, and the data already has an
Eintritt and a Vertragsänderung sharing one. Matching on the date would
eventually cancel a change nobody meant. And entries from before the
history carried values have nothing to fall back to.

Confirmation is not "are you sure" — that question gets a reflex yes by
the third time. The dialog says what will be different afterwards: which
field goes back to which value, and which one stays because something
later claimed it.

employee_history keeps its append-only policies; delete_history_entry is
SECURITY DEFINER and checks the permission itself in its first line. The
audit log keeps the deletion with the values that were removed, and the
audit log genuinely cannot be edited.

The rule lives twice — in SQL and in lib/history.ts. The database is the
authority; the copy exists so the UI can hide a button that would fail
and print the reason instead. Rehearsed against real data in a
rolled-back transaction first: the later change held, the untouched
field reverted, all four refusals fired.

Also corrected in the data catalogue: I had written that
require_hr_admin was called by nothing. It guards all sixteen mutating
functions.

64eb155dda Write down what is actually in the database
The one document describing the schema, docs/data-model.md, predates two
rebuilds. It names divisions/departments/teams and a positions table that
no longer exist, describes Supabase auth with an anon key and a service
role that were removed, and puts the policy count at 58 when it is 21.
Anyone reading it to understand the data would have been misled on every
count.

docs/datenkatalog.md replaces it, and was not typed up from memory: the
columns, defaults, keys and check constraints were read out of
information_schema and pg_catalog on the running database. Fifteen
tables, 142 columns, ten enum types, 21 policies. Where a rule appears in
prose, the constraint it comes from is named next to it.

Some of it only became visible by asking the database rather than the
migrations. generate_company_email and the is_hr_admin pair are still
defined but nothing calls them any more. Position numbers look like a
six followed by seven digits because the generator builds them that way,
not because anything enforces it — the column requires only uniqueness.
monthly_salary_gross is dead weight kept in case old rows hold data.

Three claims I drafted were wrong and the database said so: the position
number format, the event trigger's name (ensure_rls, the function behind
it is rls_auto_enable), and which tables deviate from the plain
is_hr_user() policy.

The old document keeps a pointer at the top instead of being deleted —
it is linked from the security review, and a stale document that says so
is more useful than a dead link.
