The old refusal read: "Diese Abwesenheit ist noch nicht wirksam. Sie muss
über den Vorgang selbst abgebrochen werden." There was no such way. The
row sat in the file, the scheduled change kept running toward its date,
and nothing could stop either one.
That is not hypothetical. One person went absent in July, came back in
August, and still has a second return booked for the first of September
— recorded while they were already working again. The guard added
yesterday stops a third from being written; it does not remove the one
that exists.
Absences are called off whole, not field by field. For a planned
contract change the scheduled payload gets the affected fields lifted
out of it and runs on with the rest; an absence has no fields in that
map, and half an absence is not a thing anyone means. So the whole
scheduled change is cancelled, and what it had already noted on the
person goes with it: the date they were to be away from, the date they
were to come back on. Left behind, the profile would show an absence
with no event behind it. If the absence is still running, the return
date planned when it began applies again.
The link between the row and the scheduled change had to exist first —
start_karenz and record_karenz_return now record it. Existing rows get
it backfilled, but only where one running change of that kind falls on
that person and that day. Where two would match, the row keeps refusing:
guessing which process to cancel is worse than refusing to.

A long-term absence recorded by mistake could only be undone by booking
a second event on top of it — leaving two entries in the file, the first
of which never happened. Karenz and Rückkehr can now be deleted and
corrected like the other entries.
For that to restore anything, the two operations first had to start
recording what they overwrote. start_karenz and record_karenz_return now
keep before/after the way change_employee_data does: status, kind of
absence, start, planned return — and for a return also employment type,
hours and the part-time variant. Without that there is nothing to revert
to, only a sentence.
The ordering rule HR asked for is enforced in the database, not just in
the UI: an absence cannot be deleted while a later return exists. A
return standing on its own would be a return from nothing, and the
person's status would derive from an entry whose starting point had been
deleted. Delete the return first and the absence frees up.
Rehearsed end to end on real data: absence recorded, return recorded on
reduced hours; deleting the absence refused; deleting the return put the
person back on Karenz with the original hours and the part-time variant
cleared; deleting the absence then put them back to Aktiv with no trace.
Rows written before today carry no before/after and stay untouchable,
with the reason they already gave. Planned absences are refused too —
they have their own operation, and their fields have no place in a
pending payload, which is why app_feld_karte carries a null group for
them rather than a plausible-looking wrong one.

Deleting and correcting a history entry stopped at the present: anything
not yet effective stayed put. That was not a principle, it was a missing
link. A planned change lives as a payload in pending_org_changes, and
nothing tied it to the history row — only a person and a date, and the
data already holds an Eintritt and a Vertragsänderung sharing one. So
employee_history now carries pending_id, set by change_employee_data
when it schedules something.
One planned change can carry two history rows: Stammdaten and Vertrag
are kept apart but scheduled together. Taking one back therefore strips
only that group's fields from the payload, and cancels the operation
only when nothing is left. Correcting one rewrites its group and the
effective date, and touches no employee data — the change has not
happened yet.
An entry stays on its side of the present. Pulling a planned change into
today, or pushing an effective one into the future, would mean adjusting
the employee record and the pending payload in opposite directions;
that is what the real operations are for.
Existing rows were linked where exactly one running operation matched
the person and date and no other row had claimed it. All five of them
matched. Anything ambiguous would have kept the old refusal, which now
says the actual reason.
The edit dialog surfaced a bug in useDialogFocus that predates it: the
effect depended on the identity of onClose, which almost every caller
rebuilds on render, so it re-ran after each keystroke and its cleanup
pulled focus back to whatever opened the dialog. Any dialog with a text
field would have accepted one character. It never showed because until
now no dialog kept its own state next to its own onClose.
Rehearsed against real data: a two-row planned change corrected, one row
taken back with the operation continuing on the rest, the second taken
back with the operation cancelled, and both refusals.

HR can now delete a history entry, but only where deleting one is an
honest thing to do — and deleting it also undoes it.
The rule they asked for is the interesting part: the last valid change
wins. Deleting an entry walks its fields one at a time. If a later entry
touched the same field, the current value stays — that later change is
the one in force. Otherwise the field goes back to what the deleted
entry recorded as its "before". So the middle of three entries can be
removed without an old value overwriting a newer one.
Four kinds of entry refuse to be deleted, each saying why in the place
the button would have been. Eintritt anchors the timeline. Transfers,
promotions, absences and exits moved positions and status — they have
proper operations for that, and guessing backwards is how you corrupt an
org chart. Anything not yet effective hangs off a planned change, and
that link is not trustworthy: there is no key between a history row and
its pending row, only a person and a date, and the data already has an
Eintritt and a Vertragsänderung sharing one. Matching on the date would
eventually cancel a change nobody meant. And entries from before the
history carried values have nothing to fall back to.
Confirmation is not "are you sure" — that question gets a reflex yes by
the third time. The dialog says what will be different afterwards: which
field goes back to which value, and which one stays because something
later claimed it.
employee_history keeps its append-only policies; delete_history_entry is
SECURITY DEFINER and checks the permission itself in its first line. The
audit log keeps the deletion with the values that were removed, and the
audit log genuinely cannot be edited.
The rule lives twice — in SQL and in lib/history.ts. The database is the
authority; the copy exists so the UI can hide a button that would fail
and print the reason instead. Rehearsed against real data in a
rolled-back transaction first: the later change held, the untouched
field reverted, all four refusals fired.
Also corrected in the data catalogue: I had written that
require_hr_admin was called by nothing. It guards all sixteen mutating
functions.
