# POST /pairing/unpair

`POST /pairing/unpair`

Revokes the local member record for the given peer and returns the
Engine-owned removal progress. Errors flow through the shared `ApiError`
carrier and therefore serialize to `ApiErrorResponse { code, message,
details? }` on the wire.

## Request body

- UnpairDeviceRequest
  - `peerId` string, required

## Response `200`

- MemberRemovalEnvelope — 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.
  - `data` MemberRemovalDto, required
    - `outcome` 'local_only' | 'recovering' | 'applied' | 'complete' | 'recovery_required', required
    - `pendingRecipientDeviceIds` string[], required
    - `pendingRecipients` integer, required
    - `removedDeviceIds` string[], required
    - `revocationId` string, nullable
    - `updatedAtMs` integer, required
  - `ts` integer, required — Server time when the response was built (unix epoch milliseconds).

## Other responses

- `404` — Member not found
- `409` — Member removal already in progress
