vaulted. The wallet fetches the prepared request, sends it with the cost
covered by Endstate, and resolves once the network has included it. The vault
request reads unvault_waiting once Endstate sees it, and the waiting period
the brand set for that vault starts. It takes no tap session: the vault holds
the item. Only a wallet that holds the item now can send it.
Nothing completes the unvault from this wallet. When the waiting period has
ended and nothing holds the unvault, the vault records the item’s dispatch
with its own tap and Endstate completes it.
Rejects with submission.not_executable when an unvault is already under way
or finished, with unvault.in_progress while an earlier unvault is still
settling (retry after error.details.retry_at), with
vault.request_not_found when the id names no vaulted item, with
auth.forbidden when this wallet does not hold the item, with
wallet.sponsorship_unavailable when the send cannot be covered right now
(nothing was sent), and with wallet.destroyed if the wallet has been
destroyed.
Rejects with wallet.unsupported_operation when the wallet frame Endstate
runs is older than this SDK and does not know the operation yet. Nothing was
sent. The error’s message says to upgrade the SDK, which does not apply here:
the SDK is already the newer side, so retry once the frame is updated.
