Separate write intentions from transport attempts

TL;DR

Assign one stable operation identity to the intended state change. If the intended payload changes, treat that as a new decision instead of silently reusing the previous identity.

Steps

1. Assign one stable operation identity to the intended state change. Associate each HTTP attempt with its own request ID for diagnosis, while retaining the same operation key and payload for an identical retry. After an uncertain response, recover the committed resource before creating a new operation. If the intended payload changes, treat that as a new decision instead of silently reusing the previous identity.
