Seeing a colleague's draft turned out to be half a feature: the point of
sharing it is to finish it while they are away. So writing is allowed
now -- but never by two people at once.
A draft is a single JSONB field. Whoever saves writes the whole state,
not the changed field, so two open wizards overwrite each other
completely and the second person sees nothing wrong: their own state is
right there on screen. That is why writing stayed with the owner until
now, and a lock is what makes giving that up safe.
The lock lives in the row (locked_by, locked_at) and is enforced by the
update and delete policies, not by the application. It expires, and that
is the important half: releasing happens when the wizard closes, and a
closed laptop never closes a wizard. Without expiry one crashed tab
would take a draft away for good -- worse than the problem being solved.
The wizard refreshes its lock while open so a long form does not lose it
mid-way.
Delete had to widen too, which reads like more than was asked for: the
wizard deletes the draft once the person is hired. Without it the hire
would go through and the draft would sit there forever. The card still
only offers delete on your own drafts.
Four of five mutations against the lock go red. The fifth -- dropping
`!open` from the refresh guard -- does not, because freigeben() already
nulls the ref the interval checks. The condition stays as the readable
statement of intent, now with a comment saying so.
Not run against a live database here; the CI migration job is the first
real execution.

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`).
- 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.
