A refusal's detail now stands where it is sent (HTTPException's detail,
a JSONResponse's "detail") or is returned by a factory that only ever is,
with any spread before its code and reason, so no spread can replace
them. The scan follows no variable and no kwargs any more; what it cannot
read in a reason (a lambda's or comprehension's name, a nonlocal or
global, a local that reaches itself, a constant or map changed elsewhere,
an app import it cannot resolve) is reported. The detail guard reads the
same slots and fails on anything but a code dict or a factory's call.
