Fails while any unresolved :manual region remains.
mix capstone.check [dir]D12 forbids resolving a conflict with a prompt, so apply writes a marked region and this task is the gate that keeps it from being forgotten.
Meant to run inside a GENERATED project. Pointed at this repository, prose
that quotes the marker prefix verbatim (to explain what apply writes) would
otherwise read as unresolved work -- see @pruned below for where that is
excluded.
