§0a captures m's locked picks across all 8 questions. Two divergences from
inventor recommendations reshape the model:
- Q4: hybrid — approver edits the proposed values (counter-payload) AND/OR
leaves free-text in decision_note. Adds counter_payload jsonb column.
- Q6/Q7: the counter is treated as a NEW pending approval_request authored
by the approver, not an "edit and resubmit" CTA on the requester side.
Original requester sees the old row as changes_requested ("Abgelehnt mit
Vorschlag") and the new row as pending — they can approve it themselves
if eligible (they're no longer the requested_by). 4-Augen still holds.
§3 implementation sketch rewritten: SuggestChanges atomically closes the
old row, applyRevert's the entity, spawns a new pending row with
counter_payload as payload + previous_request_id linking back, re-applies
the counter via write-then-approve, emits both *_approval_changes_suggested
and *_approval_requested events. Migration 103 adds the CHECK value plus
counter_payload jsonb + previous_request_id FK + index. Slice plan trimmed
to backend / frontend-modal / Verlauf-integration.
