Registers the account a **completed backup** handshake detected as the backup (Growth plan). Answers `200` with the account summary.

## Headers

- `Idempotency-Key` string, uuid, required

## Request body

- RegisterBackupIdentityRequest: Which completed backup handshake names the account to keep as the backup.
  - `handshake_id` string, uuid, required: A `backup` handshake of the caller's in state `completed`; the account that tapped it becomes the backup.

## Response `200`

200 with the account summary.

- object
  - `data` RecoveryAccountResource, required: Where the creator's own account stands for recovery: the accounts by display name only, whether a backup is kept, and the newest handshake of each kind.
    - `primary_display_name` string, nullable, required: The account that signs the creator in, as the connector reported it (display name, else handle, else the platform's id); null when none is linked. Connector identifiers never appear.
    - `backup_identity_registered` boolean, required: Whether a backup account is kept ahead of a ban.
    - `backup_display_name` string, nullable, required: The backup account as the connector reported it; null when none is kept.
    - `relink_handshake` unknown[], nullable, required: The newest handshake that moves the sign-in, in whatever state, so a client can pick up a flow the creator started on the dashboard or in the bot; null when none was ever opened.
      - unknown
    - `backup_handshake` unknown[], nullable, required: The newest handshake that registers a backup, in whatever state; null when none was ever opened.
      - unknown

## Other responses

- `400`: `IDEMPOTENCY_KEY_MISSING`: every write needs an `Idempotency-Key` header. Send a fresh UUID per distinct operation.
- `401`: `AUTHENTICATION_REQUIRED`: the request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an `sbt_test_` token on production).
- `403`: `TOKEN_MISSING_ABILITY`: the token is valid but does not carry the ability this endpoint requires; `error.context.required_ability` names the one to grant. An endpoint that also checks who owns a row or which tier the account is on answers `FORBIDDEN`, `TEAM_TIER_REQUIRED` or `CONNECTOR_TIER_REQUIRED` with the same status, and says so in its own description.
- `404`: `RESOURCE_NOT_FOUND`: when the handshake is not one of the caller's; `error.context.handshake_id` names it.
- `409`: `IDEMPOTENCY_KEY_REUSED`: the key was already used in the last 24 hours with a different request body.
- `422`: `VALIDATION_FAILED`: the payload broke a rule, and `error.fields` maps each offending key to its messages. A refusal from the domain, such as a plan that cannot go on sale or a member who cannot be removed, uses the same code with `error.message` saying why and no `fields`. On this endpoint: `VALIDATION_FAILED`: when the handshake is not a completed `backup` handshake, the plan lacks the feature, or the caller is not the account holder.
- `425`: `IDEMPOTENCY_REPLAY_IN_PROGRESS`: the first request with this key is still running; retry in a few seconds and the original response is replayed.
- `429`: `RATE_LIMITED`: the token has spent its 300 requests a minute or 10,000 an hour; `Retry-After` says when the next one is accepted.
