// empty and "all" keep both classes, "interactive" drops automated sessions,
// "automated" drops interactive ones, and any other value is a 400-worthy
// error. The two exclude flags are never both true (that would match nothing),
// and the error case returns the safe no-exclusion default so a typo never
// silently filters the report.
