    Class DropCopyOperation

    Single-use handle for applied drop-copy bookkeeping.

    lock(), accountAdjustments(), accountBlock(), and isAccountBlocked() may be read while the operation is live. commit() and rollback() each consume the handle; calling either a second time (or after the other) throws LifecycleError.

    Account-control operations published by the drop-copy pipeline and consumed rate-limit attempts stay outside that finalization boundary.

    Mutation finalizers carry the same contract as on Reservation: a callback that throws is re-surfaced here as PolicyCallbackError without stopping the batch, and independently arms the engine kill switch, which blocks every account for a Mutation registered from JavaScript. Later pre-trade calls are rejected with SystemUnavailable until an operator calls engine.accounts().unblockAll().

    • Returns void

    • Returns the account adjustments produced by this operation.

      Errors

      Throws LifecycleError when the operation has been finalized.

      Returns AccountAdjustmentOutcome[]

    • Returns the first account block requested by this operation, or undefined.

      This request-local history may differ from the apply-time registry snapshot reported by isAccountBlocked().

      Errors

      Throws LifecycleError when the operation has been finalized.

      Returns AccountBlock | undefined

    • Commits the applied bookkeeping.

      Errors

      Throws PolicyCallbackError when a mutation commit callback throws, or LifecycleError when the operation has already been finalized or its owning engine is re-entered from one of its callbacks.

      Returns void

    • Returns void

    • Returns the apply-time blocked-state snapshot for the order account.

      The snapshot was captured before applyDropCopy returned and does not track later registry changes.

      Errors

      Throws LifecycleError when the operation has been finalized.

      Returns boolean

    • Returns the lock payload accumulated for this operation.

      Errors

      Throws LifecycleError when the operation has been finalized.

      Returns Lock

    • Rolls the applied bookkeeping back.

      Errors

      Throws PolicyCallbackError when a mutation rollback callback throws, or LifecycleError when the operation has already been finalized or its owning engine is re-entered from one of its callbacks.

      Returns void
