# Update Evaluation

`PATCH /api/mind/v2/evaluations/{evaluation_id}`

## 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}`
- Auth: none declared

Edit a MindEvaluation's confidence (TOS-128 A2-followup).

Confidence-only: proposition text is the canonical extracted claim and its
identity (claim_key, hash) depend on it - mutability of text is a deeper
design question deferred for now. Identity-scoped via the same ownership
gate the other evaluation routes use.

## Path parameters

- `evaluation_id` string, uuid, required

## Headers

- `x-impersonate-identity-id` string, nullable

## Request body

- V2UpdateEvaluationRequest: Body for PATCH /evaluations/{id} - confidence-only edits (TOS-128 A2-followup). Proposition text is intentionally NOT editable here: claim_key, summary, and the proposition hash are derived from the text and identify a shared belief across Minds. Mutating them is a deeper design question deferred to a follow-up.
  - `confidence` number, required
