Second half of the mass import: the transactional loader, the /import page
and a template generated from the same schema the validation uses.
Everything happens in one transaction. A half-loaded organisation — areas
without departments, positions without people — is worse than none, because
it looks like data. The dry run is the same code path with a rollback at the
end, so the report is built against the real current state rather than a
copy, and nothing is cached between checking and committing: the file is
sent twice. That costs one upload and avoids server-side state that can
expire, fill up, or be confused between two people.
Personnel numbers are taken from the file, not reassigned. personnel_number
is GENERATED ALWAYS AS IDENTITY, so this needs OVERRIDING SYSTEM VALUE and a
hand-written insert — worth it, because the number is on payslips, in files
and on badges. An import that reissues it is not a migration. The identity
counter is advanced afterwards; without that the next hire draws a number
the import already used, and the unique index refuses it weeks later, far
from the cause.
Three defects the first real run against the database exposed, none of which
typecheck, lint or 231 tests could have found:
- weekly_hours is bound to employment type by a CHECK constraint: full time
is exactly 38.5. The import reached the insert and was rolled back. Now
it is a finding with a row number.
- Titles are restricted to a fixed list by another CHECK. Same treatment.
- setval() needs UPDATE on the sequence, which `usage, select` does not
grant. Migration 20260803120000 adds it; until it is applied, an import
containing people will fail at the last step and take itself back.
I also had exit_date > entry_date where the database has >=. Someone who
never starts enters and leaves the same day; the stricter rule would have
rejected a real case.
Verified against the live database through the actual route and session: a
file with four deliberate faults produced exactly four findings, each with
sheet, row and column, and the rollback left nothing behind.

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.
Also included, uncommitted until now

validity and role/employment fields, with their migrations and UI.
