The app runs against a real database for the first time since the port, and
two things were broken. Both were invisible to typecheck, lint, 192 tests
and the build.
Sign-in looped. Auth.js created the session and app_upsert_user() adopted
the existing profiles id correctly — the row was in app_users, right id and
all — but the proxy builds its own Auth.js instance from lib/auth/config.ts
alone, and the session callback that copies token.uid onto session.user.id
lived in auth.ts. So the proxy saw a session without an id, treated every
signed-in user as signed out, and sent them back to /login. Click, flash,
login page: from the outside it looked like the button did nothing.
The callback moves to the config both instances share. auth.ts now spreads
the base callbacks instead of replacing them, which is the mistake that
would reintroduce this.
The proxy test did not catch it because its fixture hands the handler a
session that already has user.id — it tested the routing, not the shape
Auth.js actually produces.
Then the dashboard crashed on a.date.localeCompare. PostgREST returned JSON:
a `date` arrived as "2026-08-03", a `numeric` as a number, and that is what
lib/supabase/types.ts declares and what every sort, every date comparison
and every status derivation assumes. The pg driver does the opposite — Date
object and string respectively. The declarations stayed true to what the
code believes; only the runtime value changed, which is why nothing flagged
it.
The driver is configured back to the declared shapes in lib/db/pool.ts,
rather than rewriting 49 call sites. That also removes a timezone hazard:
`date` is a calendar day, and as a Date object it acquires midnight in the
server's zone — a birth date would shift by a day in Austria, always. The
same class of bug as in the seed.
int8 stays a string on purpose: it only comes from count() and is read
through Number() everywhere; parsed as a number it would quietly lose
precision past 2^53.
A missing sign-in error now reaches the server log. Auth.js was failing
silently — a 302 back to /login and nothing to read. That was its own
defect, and it is the reason the first diagnosis took as long as it did.
Verified against the live database: all six pages render, 797 active of
852 records, 744.4 FTE, and a detail page shows birth date 15.08.1968
against SV number 7960 150868 — the digits agree, so no day has shifted.
Both new tests were checked by mutation: remove the fix and they fail.

Auth.js replaces GoTrue. The sign-in still goes to the same Entra tenant,
but nothing sits between the app and the identity provider any more — the
code exchange, state, nonce and the session cookie are ours.
lib/auth/session.ts stays the only place that knows where a user id comes
from, which is why this was one file and not fifty. What it returns is now
app_users.id. app_upsert_user() maps the Entra `oid` onto it, and for an
address that already has a profiles row it adopts that id instead of
minting a new one — otherwise everyone would have been signed in and cut
off from their own notes, drafts and audit trail at the same time.
That upsert is the one write that cannot have a session context yet: the
id is what it produces. It runs as a SECURITY DEFINER function that may
touch app_users and nothing else, which is a far smaller lever than the
service key that used to answer this class of problem.
The proxy no longer checks HR rights. It has no database connection, and
putting role/is_active in the token would have frozen the claim until the
next sign-in. The check moved to where it can read the current truth: the
app layout on every render, requireHrUser() for the export routes, and
underneath both, RLS.
Two things only came out by running it:
- `export const proxy = auth(…)` is not a function declaration, so
Next.js never found it and every request 404'd. `next build` reported
success and listed the proxy. In the function config form auth() also
returns the handler as a promise, so it needs an await. The proxy test
now mocks it as a promise for that reason — a friendlier mock would
let the same bug back in.
- A missing AUTH_MICROSOFT_ENTRA_ID_ISSUER silently falls back to
/common/, and the redirect really did go there. That would let any
Microsoft account sign in, including a private one, and it would never
look broken. It now refuses to start in production.
Neither build nor image needs credentials any more: the pool is created on
first use, the auth config is evaluated per request, and there are no
NEXT_PUBLIC_* values left to bake in. One image now runs in every
environment.
Verified: typecheck, lint, 187 tests, build, and by hand in the browser —
/employees redirects to /login, and the sign-in button reaches the Entra
page with PKCE and the callback URL that goes into the app registration.
Not verified against a real database; there is still no DATABASE_URL.
