# POST /member/device-trust/decision

`POST /member/device-trust/decision`

## Request body

- DecideDeviceTrustRequestDto
  - `changeId` string, required
  - `choice` 'apply_change' | 'keep_current_device_group', required
  - `confirmLocalRemoval` boolean

## Response `200`

- DeviceTrustDecisionEnvelope — Canonical success envelope: `{ "data": T, "ts": <unix millis i64> }`. `ts` is `chrono::Utc::now().timestamp_millis()`, set in the webserver handler via [`ApiEnvelope::now`] (the contract carries only the type + the clock helper, not a hard dependency on when the handler reads the clock). `rename_all = "camelCase"` is a no-op for the single-word fields here but is declared for forward-compat. IMPORTANT (utoipa v4): every concrete `ApiEnvelope<X>` that needs a named OpenAPI component is declared in the `#[aliases(...)]` block below. Add a new alias line whenever a new payload type needs enveloping. NEVER register the bare `ApiEnvelope` in `components(schemas(...))` — utoipa errors on a bare generic, and an un-aliased generic inlines an anonymous schema.
