Membership Commerce fence

The Lifecycle

Transitions Explained

Commerce claims a document and records its fence while cancellation or amendment is pending. Cancellation completion clears its fence. The renewal fence is vocabulary only; pending renewal detection instead reads a pending term.

What Cannot Happen

Amendment execution is refused and supplies no normal fence-clearing path. A declared renewal fence is not evidence that a writer exists.

Concurrency and Timing

Claims share Commerce’s transaction and take the holding lock. Preparation rejects fenced work, while fulfilment treats an outstanding fence as retryable.
