Clicking "Wiedereinstellen" could never succeed. rehire_employee has always
demanded a position and refuses without one, but the panel offered only a
date and sent only a date — so every rehire ended on an error the dialog
gave no way to fix.
The panel now picks from the open positions, the same list and layout the
transfer panel uses, and warns before submitting when the date falls outside
the chosen position's validity. The old position is deliberately not a
silent default: it may since have been filled, ended, or gone.
Behind that sat a second fault, hidden by the first: the status assignment
status = case when v_date <= current_date then 'Aktiv' else 'Geplant' end
is text, and the column is employment_status. Postgres refuses that outright,
so the function would have failed even with a position. It surfaced only once
the earlier check stopped firing — the same pattern as hire_employee this
morning, where three faults sat in a queue.
rehire_employee also placed people without checking anything. It now applies
the rule from 20260810100000: the date must lie in the position's validity,
and no assignment may still stand. A rehire could otherwise land on an
occupied position and be caught by the partial index, with a message that
explains nothing.
My first verification of the cast was wrong and passed a broken state:
plpgsql converts silently when assigning to a variable, so the probe proved
nothing. Redone as an UPDATE against a column, which is the case that fails.
Verified end to end against the live database, rolled back: Stefan Egger
returns as Aktiv on a free position, with the assignment and the
Wiedereintritt entry. Without a position, on an occupied one, and on one not
yet valid, it is refused — each with its own message.

Accessibility work on the UI layer, all of it rooted in one structural gap:
there were no form primitives, so every field was hand-assembled and every
field got the same details wrong.
Form primitives
- components/ui/Field.tsx (Field/TextField/SelectField/TextareaField) and
Button.tsx. Field generates the control id with useId and derives htmlFor
from it, which is what makes the association impossible to omit rather
than merely conventional.
- 92 labels existed, 4 used htmlFor, and no input carried an id at all: a
screen reader announced an unnamed edit box and clicking a label focused
nothing. Now every label resolves to its control (0 unassociated), and the
input class chain that appeared verbatim 85 times appears zero times.
- Field also takes a render prop, so Lookup, CountryPicker and Picklist get
the same wiring instead of a second, partial solution.
- SearchInput replaces three hand-rolled copies of the icon-in-a-box search
whose input had only a placeholder — not a label — and killed its own
focus ring with outline-none and nothing in its place.
- Toggle groups (workdays, reorg change type) became fieldsets with
aria-pressed; colour alone was carrying the selected state.
Comboboxes
- Lookup and CountryPicker were text inputs with a div of clickable buttons
underneath: typeable, but no keyboard path to a result and nothing telling
a screen reader a list had appeared. Both now carry role=combobox,
aria-expanded/controls/activedescendant and listbox semantics, with arrow
keys, Enter and Escape. Escape stops propagation, or it would close the
surrounding dialog along with the dropdown.
Dialogs
- useDialogFocus centralises what Modal and SlideOver each owed the
keyboard and neither provided beyond Escape: focus into the dialog on
open, Tab and Shift+Tab cycling within it, focus restored to the trigger
on close.
- SlideOver stays mounted for its transition, and aria-hidden does not
remove anything from the tab order — so every closed panel was leaving
invisible tab stops at the end of the page. `inert` fixes that.
Route states
- loading.tsx, error.tsx, not-found.tsx and global-error.tsx. Every page in
the (app) group is server-rendered per request, so without loading.tsx a
navigation showed nothing at all until the server answered, and a render
error dropped the user on Next's own screen with no way back.
Tests
- 22 component tests (vitest jsdom project). Two of them found limits of the
environment rather than of the code: jsdom implements neither `inert` nor
scrollIntoView, so the inert test asserts the attribute and the missing
scrollIntoView — which was taking the whole render down from inside an
effect — is stubbed in the setup file.
Reworks the app from a two-role (hr_admin/manager) model to a single
HR-only role gated by profiles.is_active, fixes transfer/promote/karenz/
reorg RPCs to actually defer future-dated changes via a new
pending_org_changes table instead of writing them immediately (applied
by a daily Vercel Cron route), makes reorg undo append-only instead of
deleting history, adds Karenz-return and history-date integrity guards,
deprecates the salary column, and adds explicit schema grants + perf
indexes needed to run against a fresh (non-hosted) Postgres instance.
Adds vitest unit + integration test suites (the latter against a real
local Supabase instance) covering all of the above, plus lint/typecheck/
build wiring (`npm run check`).
- supabase/functions.sql, functions_2.sql: Postgres RPCs for every
employee/position/reorg mutation (hire, terminate, transfer, promote,
start/adjust/return karenz, change data, rehire, create position, staff
internally, apply/undo reorg). Each resolves manager_id server-side,
writes history + audit atomically, and enforces hr_admin via
require_hr_admin() (backed by the existing RLS policy).
- actions/employees.ts, positions.ts, reorg.ts: Server Actions wrapping
the RPCs, returning success/error for client-side toast handling.
- Employees list (search/filter/pagination) and detail (4 tabs: Stammdaten,
Vertrag & Gehalt, Organisation, Historie) reading from employees_directory.
- 6 action slide-over panels: Transfer, Promote, Karenz (start/adjust/
return), Daten aendern (person+contract diffing), Terminate (with direct-
report reparenting warning + offboarding checklist), Rehire.
- lib/org.ts: shared division/department/team/location lookups.
Verified live: promote mutation updates salary, writes history/audit, and
the detail page reflects it after refresh, no console errors.
Note: the spec's Karenz-verwalten panel only covers employees already on
Karenz; added a start-Karenz mode (Karenzbeginn/geplante Rueckkehr) to
cover the Aktiv-employee case implied by the header button but not
specified in the panel list.
