The three differences left after replaying the log were ours on purpose. A log
has to score the same in both programs, so they now follow N1MM:
- ARRL DX and CQ WW RTTY count the 14 Canadian areas N1MM lists as `48SDC14P`,
which keeps Newfoundland apart from Labrador. A station sending the postal
code is counted as the area the contest names.
- A maritime mobile is scored from the call it signs. CQ WW says it counts for
the zone alone; N1MM gives it the country, and so do we.
- A callsign the country file cannot place counts as a multiplier with an empty
value, so every unplaceable call worked on a band shares one multiplier.
29 of the 37 contest instances in the log now agree with N1MM on every contact
and on the totals. What is left is the country file of the day and rows whose
cached points N1MM never worked out again after a call was corrected.

Two pieces of work on the scoring engine.
The .udc reader now takes N1MM's published scoring vocabulary: the full
PointsPerContact condition set, the PointsMultBy family, PowerMult, BonusPoints,
the multiplier sources and the settings that say which stations bring a
multiplier in. MultMult is a weight rather than a switch, as in N1MM's
ComputeScore. The entry categories and the sent exchange reach the rules in a
new ContestEntry, so a contest can score by the power category it is entered in
or by what this station sends.
Then every contest in a real N1MM log was scored again from these rules and
compared with the points and multiplier flags N1MM wrote. That found five bugs:
ARRL DX and IARU read the exchange from the wrong column, a stored " " was read
as a value rather than as empty, CQ WW RTTY's own Canadian area names were not
counted, a maritime mobile scored nothing, and a contact in a mode the contest
does not run scored as if it were in the contest.
docs/n1mm-interop.md has the check and what still differs.

CQWWRTTY resolved to the built-in CQ WW with the mode set to digital, and then
scored it as though it were the CW running: a contact inside your own country
worth nothing, two multiplier types, and CQ-WW-SSB in the Cabrillo header. Every
one of those is wrong for RTTY, and wrong quietly, which is the worst way.
RTTY is a different contest wearing the same name. Every contact scores — 1
inside your own country, 2 on your own continent, 3 off it. The exchange carries
the state or province after the zone, and that is a third multiplier per band.
A station outside the US and Canada sends DX there, so the box is not required
and DX brings no multiplier.
The state box being optional is deliberate: most of the log is DX stations, and
holding up an entry for a box that will hold DX costs more than it is worth.
