While somebody is on a long-term absence their reports report to the next
management level, and it keeps rolling up until it reaches somebody present.
Derived at read time in lib/acting-manager.ts rather than written to
employees.manager_id: the absent person stays formally in charge, so the
stand-in has to be visible as a stand-in rather than quietly replacing them.
Both ids therefore travel to the UI, and both sides carry a badge — the
absent person ("Abwesend · Vertretung: X") and anyone now reporting
elsewhere ("Vertretung für Y").
Three cases the walk has to survive, all covered by tests:
- Several absent levels in a row — it keeps climbing, and still names the
*recorded* manager as the one being covered for, not the level skipped.
- Everyone above absent — it stops and keeps the recorded manager. Re-rooting
a team to the top of the chart would distort more than showing an absent
manager whose absence is labelled anyway.
- A manager_id cycle, which nothing in the schema forbids.
An absent lead needs no separate deputy field: their stand-in is simply
their own acting manager, the same one their reports moved to.
Data model
- employee_assignments records org placement over time (valid_from/valid_to),
written by a trigger on `employees` rather than inside each RPC: ~70
`update employees` statements spread over fifteen migrations mean per-call
bookkeeping would miss paths today and again with every future RPC. A
partial unique index enforces the one-open-interval invariant the trigger
relies on when closing the current row.
- The Organigramm gains a Stichtag (default today). Membership comes from
entry/exit/karenz, past placement from the new history, future placement
projected from pending_org_changes. Placements predating the migration are
backfilled with today's values and flagged as such in the UI, since
employee_history only ever stored free text and cannot be reconstructed.
Correctness
- Reports and exports silently truncated at PostgREST's 1000-row cap
(db.max_rows); employee_history is already past it at ~800 staff. Every
whole-table read now pages explicitly.
- XLSX date cells were a day early: ExcelJS converts a Date to an Excel
serial straight off getTime(), so a Date built at local midnight lands on
the previous day's serial in any positive-offset zone.
- Date handling is pinned to Europe/Vienna throughout, and date-only strings
are formatted without a Date round-trip. The dashboard's YTD window was
built by round-tripping a local Date through toISOString(), which shifted
it a day early and dropped 31 December entirely.
- Export routes parsed measure/group/split/eventType with unchecked `as`
casts, so an unknown value reached column headers as `undefined` and the
Content-Disposition filename. Parsed against the label maps now, with the
filename slugged as a backstop.
- toXlsx keyed columns by header text, silently dropping the second of any
two columns sharing a name — split columns take their header from data.
- The org chart tree walks had no cycle guard; nothing in the schema forbids
a manager_id cycle, and one would hang the tab rather than misreport.
- The login page reflected ?error= verbatim, letting anyone put arbitrary
text on the real sign-in screen; messages are looked up by code now.
- React Flow needs elementsSelectable on, or it sets pointer-events:none on
the whole node and the expand control stops responding.
UI
- Mobile: the shell was unusable below lg — a fixed 236px margin pushed
content off-screen with no mobile navigation at all. The sidebar is now a
drawer, dvh replaces vh, safe-area insets are honoured, inputs are 16px so
iOS stops zooming on focus, and form grids stack.
- Org chart nodes redesigned: per-kind accent stripes and icons, vacant
roles called out, expand control moved to the bottom edge carrying the
child count.
- Pagination is windowed; it previously rendered one link per page (54 for
the employee list, unbounded for the audit log).
- Positions page reduced to open positions with a single "Besetzen" action.
- The employee Organisation tab links into the org chart focused on that
person, reusing the chart's existing search-match highlighting.
