# POST /v2/setup/initialize

`POST /v2/setup/initialize`

## Request body

- InitializeSpaceRequest — Request body for `POST /v2/setup/initialize`. Maps to `SpaceSetupFacade::initialize_space(InitializeSpaceCommand)`.
  - `deviceName` string, nullable
  - `passphrase` string, required
  - `passphraseConfirm` string, required

## Response `200`

Space initialised

- SetupInitializeEnvelope — 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` InitializeSpaceResponse, required — Response body for `POST /v2/setup/initialize`. Mirrors `InitializeSpaceResult` flattened to wire-friendly strings.
    - `fingerprint` string, required
    - `selfDeviceId` string, required
    - `spaceId` string, required
  - `ts` integer, required — Server time when the response was built (unix epoch milliseconds).

## Other responses

- `400` — Passphrase mismatch or device name missing
- `409` — Setup already completed
- `500` — Internal error
- `503` — Facade not assembled
