The matching "five rules" were already documented; add the parts that were only
in code: the per-QSO Explain trace (Test a callsign in the award editor), the
Missing-refs gap finder (in-scope-but-no-reference + bulk assign), how one QSO
credits several references (n-fer POTA / VUCC grid lines, comma/semicolon split),
code-vs-exact matching, and how built-in award updates skip awards you've edited.
