A handoff request is not a transfer of responsibility.
I built Northline, a custody passport for workflows where accountability must remain explicit during a handoff.
The receiver can verify the load, seal, units, condition, and photo evidence. Even when every check is complete, custody has not moved.
Only explicit acceptance creates the Transfer Imprint, locks the new custody sheet, and makes Northline the current custodian.
When the handoff expires, no imprint is created. Charlotte remains responsible. An exception can be assigned to Jordan Lee, but exception ownership does not transfer custody.
The central design principle:
Responsibility moves only when acceptance leaves a permanent imprint.

I’ll add a closer look at the accepted and expired states in the comments.
