Posting rules: stages, quorums and the approval status field — Submitting, and what a rejection does

Submit for approval on the record opens stage one and fans out its asks. Submitting needs only view access — asking is the point. The requester can withdraw while the journey is in flight. A rejection anywhere drops the record to Changes requested, with the approver's reason attached, and edits unfreeze so the record can be fixed. What resubmitting does is the policy's choice: restart from the first stage (the record changed, so earlier approvals are stale — the safe default) or resume at the stage that said no, keeping earlier answers for long chains where a late no shouldn't re-tax early approvers.
