A plan settles an asked build from the build records (hq issue 214)

Browse Source 
A merge to the controller's own repository replaces the controller in its first tier; the build
that produced the new one was recorded, the plan never heard it, and it waited for ever with every
later plan behind it. The record is the fact: a build recorded after the ask is the tier's outcome,
whoever was listening when it came.
