What vision.promote_candidate does on Visionmcp

Why vision.promote_candidate is rated Medium
Promoting a record is a state-change/write operation — it advances a candidate to a higher status. It is reversible (there is a sibling 'rollback' tool on the server), so it does not qualify as Destructive. It does not execute arbitrary code or move money. The access control note ('refuses system/auto reviewers') slightly lowers blast radius but misuse could still inappropriately advance unvetted records.
From the tool's definition Promote a V2 record via V2Record.promote(); refuses system/auto reviewers.
