Soft flags
  • tie_handling_differs

A soft flag is an ambiguity the deterministic rules noticed but could not resolve. Any one of them keeps a pair out of Grade A.

These contracts have not been semantically verified yet, so no rule-by-rule comparison is available. The grade rests on deterministic scoring alone.
