Feature requests from live use:
- "Daten aendern" was missing a "Wirksam ab" field (unlike Versetzen/
Befoerdern/Karenz, which all have one) - every change was silently
logged with today's date. Added the field, threaded through
change_employee_data (defaults to today if omitted).
- Staatsbuergerschaft and Wohnland now use a searchable picker
(components/ui/CountryPicker) over the full 193-country UN member
state list (lib/countries.ts) instead of the original ~9/5-value
picklists. Dropped the now-too-narrow CHECK constraints
(supabase/schema_2.sql) since the app is the source of truth for
valid values, same approach used elsewhere for large open-ended
pickers.
Two more real bugs found via live testing of the above (both in
change_employee_data, supabase/functions.sql + functions_4.sql):
1. `text[] || 'literal'` is ambiguous in Postgres - it can resolve to
the array||array overload and try to parse the plain word as array
syntax ('{...}'), failing with "malformed array literal". Hit on
every single field-diff line the moment a user actually changed
something (Staatsbuergerschaft first, then Beschaeftigungsausmass
confirmed the same root cause). Fixed everywhere by switching to the
unambiguous array_append() function.
2. The contract_end_date diff-check cast an empty string straight to
date ("invalid input syntax for type date: ''") instead of using the
same nullif(...,'')::date guard the UPDATE line below it already had.
Verified live end-to-end after both fixes: changed Staatsbuergerschaft
to Brasilien with a backdated effective date, save succeeded, Stammdaten
tab reflects it, and employee_history got the correct event_date
("2026-07-01") and description ("Geänderte Felder: Staatsbürgerschaft,
wirksam ab 2026-07-01"). Reverted the test employee's data back
afterward; seed data is clean again.
Reports (§4.8):
- lib/reports.ts: generic server-side aggregation engine over 9 measures
(Headcount, FTE, Eintritte, Austritte, Ø Bruttogehalt, Teilzeitquote,
Ø Alter, Ø Zugehoerigkeit, Frauenanteil) x 10 group-by dimensions, with
an optional second-dimension split (disabled for average-type
measures) and per-row drill-down data.
- app/(app)/reports/page.tsx: reads filters from the URL, fetches the
matching employees_directory rows server-side, aggregates in Node
(not shipped raw to the client), computes the total.
- ReportsPageClient: measure/group/split/filter controls, 6 preset
chips, saved-reports list (actions/reports.ts), CSV export
(client-side blob download), stacked bars with a color-keyed legend
when split is active, and click-to-drill-down into the underlying
people (capped at 12, "+N weitere", linking to /employees/[id]).
Audit log (§4.9):
- app/(app)/audit/page.tsx + AuditFilters: search (target/details/actor)
+ action-type filter, paginated table with colored action badges,
row links to the affected employee when target_employee_id is set,
and the required "unveraenderbar" footer note.
This completes every route from the spec's information architecture:
Dashboard, Mitarbeiter:innen (list+detail), Organigramm (3 views),
Positionen & Bereiche, Berichte, Audit-Log, plus the Hire wizard and all
6 action panels reachable from them.
Final verification: clean npm run build + tsc --noEmit, then a full
browser walkthrough of all 6 authenticated routes as hr_admin (zero
console errors, zero 5xx responses) and a role-check pass as the
manager test account confirming action buttons and the "+ Neueinstellung"
button are hidden, and salary is masked as "... (ausgeblendet)" on the
Vertrag & Gehalt tab. Swept the database for leftover test data from
the debugging sessions above - none found, seed data is clean.
- components/orgchart/: 3-way segmented view sharing one server fetch
(switching tabs doesn't refetch):
- EmployeeTree: expand/collapse hierarchy from the CEO down, search with
auto-expand-to-match and highlighting, "Bereiche anzeigen" /
"Alles einklappen".
- PositionTree: models the org *structure* (GF -> Bereichsleitung ->
Abteilung -> Teamleitung -> grouped IC positions by title, expandable
to the actual holders) independent of who's currently in it, plus
dashed rows for open requisitions linking to /positions.
- ReorgWorkbench: batch multiple moves (employees / whole team / whole
department / whole division as source, always a specific team as
target), live headcount-impact table, apply via the existing
apply_reorg RPC, and an undo card wired to undo_reorg.
Bug found via live apply+undo testing: undo_reorg's cleanup DELETE on
employee_history silently matched zero rows, because that table has no
DELETE policy at all (by design, for audit immutability) - RLS filters
DELETE-eligible rows to none rather than erroring. Added
supabase/functions_3.sql: a policy scoped to hr_admin deleting only rows
that carry a reorg_scenario_id, so every other history event type stays
genuinely immutable. Verified live: apply moves an employee and updates
the headcount table correctly; undo reverts team/division/manager AND
now actually removes the Reorganisation history entries it created.
Simplification flagged here (not hidden): the spec's "Ganzes Team /
Ganze Abteilung / Ganzer Bereich" reorg moves the structural org unit
itself to a new division; this implementation resolves all four move
kinds down to individual employee moves against a specific target team,
since the schema's team->department->division chain doesn't support
freely reparenting a team object without also picking a department. The
workbench UI, headcount-impact math, and apply/undo all work correctly
under this model - only the exact "move the team as a unit" semantics
differs from the literal spec wording.
- components/hire/: 4-step Hire Wizard (Person/Position/Vertrag/
Zusammenfassung) matching sec4.4, with a HireWizardProvider context so it
can be opened both from the global "+ Neueinstellung" button and from a
"Fortsetzen" link on a saved draft.
- actions/hireDrafts.ts: save/delete hire_drafts (owner-scoped RLS already
in place from Phase 1). Dashboard now shows the "Entwuerfe" card the
Phase 1 plan deferred, since the wizard it depends on now exists.
- lib/positions.ts: shared open-positions loader (position number, org
breadcrumb, resolved manager name) used by both the wizard and (later)
the Positions page.
Two real bugs found via live testing and fixed in supabase/functions.sql:
1. hire_employee/rehire_employee: a two-branch CASE returning bare string
literals defaults to `text`, not the target enum, so `status = case
when ... then 'Geplant' else 'Aktiv' end` failed against the
employment_status column. Fixed with an explicit ::employment_status
cast on the whole CASE expression.
2. Postgres precedence gotcha: ->> and || sit at the *same* precedence
tier and left-associate, so `payload->>'first_name' || ' ' ||
payload->>'last_name'` does not group the way it reads - it tries to
apply ->> to an intermediate text value and fails with "operator does
not exist: text ->> unknown". Fixed by parenthesizing every ->>'...'
expression that participates in a || chain.
Also fixed: hire_employee referenced v_position.title outside the branch
that assigns v_position, raising "record not assigned" whenever a hire
wasn't tied to a position_id; extracted a v_job_title variable instead.
Verified live end-to-end: wizard search -> select position -> submit
creates the employee, closes the position, and writes matching
employee_history + audit_log rows atomically.
- 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.
