# spread.reopened

POST 

Fires once per reopen: an analyst reopened a finalized spread to edit it. The `final` snapshot it points at is kept and unchanged, but the figures are under revision until the next `spread.finalized`, so mark your copy stale. The payload carries ids, not figures.

## Request

### Headers

- `SpreadSpace-Signature` (string, required) — Signature over the exact request body: `t=<seconds since the Unix epoch>,v1=<lowercase hex HMAC-SHA256 of "{t}.{body}" keyed with your endpoint's signing secret>`. Verify it before trusting the body, and reject a `t` more than five minutes from your own clock. During a secret rotation both the new and the previous secret verify for 24 hours; each delivery is signed with exactly one.
- `SpreadSpace-Event-Id` (string, required) — The event id, identical to the body's `id`. Stable across retries and replays, and shared by every endpoint one event fans out to. Delivery is at-least-once, so dedupe on it.

### Payload

- `id` (string, required) — Event id: `evt_` plus 24 lowercase hex characters. Also sent as the `SpreadSpace-Event-Id` header. Stable across retries and replays, so dedupe on it.
- `type` (enum, required) — Always this event type on this body.
  - Allowed values: `spread.reopened`
- `created` (long, required) — Seconds since the Unix epoch at which the event was created server-side. Seconds, not milliseconds. Deliveries are not ordered; reconcile on this.
- `tenant_id` (string, required) — The workspace the event belongs to. Reject a delivery whose tenant does not match the endpoint you registered.
- `livemode` (boolean, required) — `true` for live activity, `false` for test mode (an `ss_test_` key or the sandbox simulator). Branch on it to route test deliveries to a staging handler.
- `data` (SpreadReopenedPayload, required) — The `data` object on a `spread.reopened` delivery, sent once per reopen: an analyst reopened a finalized spread to edit it. The board is unlocked and the `final` snapshot it pointed at is kept unchanged, but the figures are under revision until the next `spread.finalized`, so a receiver holding a copy should mark it stale. A pointer, not a payload: ids and the version only, no figures and no names.

## Types

### SpreadReopenedPayload

The `data` object on a `spread.reopened` delivery, sent once per reopen: an analyst reopened a finalized spread to edit it. The board is unlocked and the `final` snapshot it pointed at is kept unchanged, but the figures are under revision until the next `spread.finalized`, so a receiver holding a copy should mark it stale. A pointer, not a payload: ids and the version only, no figures and no names.

- `loan_id` (string, required) — The loan whose spread was reopened.
- `borrower_id` (string, required) — The borrower that owns the loan.
- `spread_board_id` (string, required) — The saved spread board that was reopened.
- `snapshot_id` (string, required) — The `final` snapshot that was in force when the board was reopened. Kept and unchanged; the next finalize mints a new version alongside it.
- `version` (integer, required) — That snapshot's per-loan version number.
- `reopened_at` (datetime, required) — Server-side wall-clock time of the reopen.
