# Revert Ratified Evaluation

`POST /api/mind/v2/evaluations/{evaluation_id}/ratify-revert`

## Request

- Base URL: `https://app.thinqos.com` (the document declares no server; this is the origin it was published from)
- URL: `https://app.thinqos.com/api/mind/v2/evaluations/{evaluation_id}/ratify-revert`
- Auth: none declared

One-tap revert for an earned-stable promotion (TOS-1982 Phase 1).

Demotes ``protection_level`` from ``'system_stable'`` back to
``'system_consolidated'`` - the rung ratification promoted it from.
No-op safe: an evaluation that is not currently ``system_stable`` is
returned unchanged (204), mirroring ``/unlock``'s no-op-safe shape.
``confirmed`` and ``confidence`` are never touched - reverting changes
how earned-stable a belief is, not whether or how strongly it is held.
Emits its own ELEVATE-kind cognitive_event (``action='revert'``) as the
undo journal row, mirroring the promotion side's event in
``ConsolidationService._ratify_stable_abstractions``.

**This is a durable veto, not a temporary demotion.** The ELEVATE
``action='revert'`` event this route writes is also the marker
``ratification.gather_ratification_candidates`` checks
(``RatificationEvidence.was_user_reverted``) - once an evaluation has
been reverted through this route, the automatic ratification sweep
never re-promotes it again, even if it still satisfies every other
criterion. The user retains their own promotion paths (``/confirm``,
``/lock``); only the automatic rung stops overriding this decision.
