Blast Radius , when launched in --serve mode, does some pretty weak error reporting, and does nothing to help users resolve problems. It asks the user to look into several possible issues, rather than checking itself...

To observe the current (undesired) behavior, run Blast Radius in an empty directory:

[...]$ mkdir tmp
[...]$ cd tmp
[...]$ blast-radius --serve

For maps of the form map[*something]struct{} we can render these specially as a set (i.e. don't bother rendering the empty struct every time).
Similar could be done for map[*something]bool but that's less safe as that might not actually be a set
