Announce responsibility changes
What It Does
A responsibility assignment or delegation changes.
The Flow
When Something Fails
The hop rows identify each retry boundary, any state left behind and the available observer. Assignment or delegation occurrence identity deduplicates publication; assignment replacement identity selects the original notice for withdrawal. Matching responsibility and scope can fold repeated notices, while different scopes remain separate.
Open Design Questions
Ending before dispatch still publishes the ending notice after cancelling assignment work. Derived assignments, role defaults and nightly reconciliation produce no notices. A non-production test header can delay notice work by up to a day.
