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.
Theoretical cross-market edge
Grade A pairs only, from executable book prices with depth simulation
