Reverse billing in one operation
What It Does
Billing cancellation retains its financial preparation even when a later money return fails. The operation record explains the outstanding return instead of automatically undoing billing.
The Flow
The numbered hops identify the participating services, synchronization boundary and evidence. Branch conditions in the frontmatter explain where preparation, completion and recovery diverge.
When Something Fails
Each hop records its rollback, retry or compensation boundary and the result visible to callers or operators. External outcomes can remain unresolved after local preparation commits; the listed recovery behavior defines what remains pending.
Open Design Questions
The unresolved matters are recorded in the module findings; this workflow does not establish additional product approval.
