Submit an association communication request
What It Does
A producer submits association e-mail alongside its business transaction.
The Flow
When Something Fails
The hop rows identify each retry boundary, any state left behind and the available observer. The producer key selects the same stored request and queue pointer on retry. Pointer uniqueness and dispatch claims coordinate repeated submission and queue publication.
Open Design Questions
HTTP and IAM callers use the same validated submission contract with their own transaction boundary. Scheduled dispatch recovers a missed post-commit nudge.
