This hand has a confirmed yaku through the triplet of hatsu. However, ''it did not have any yaku when calling the 789-sou''. Therefore, this hand cannot win when rule #1 is in effect. With rule #2, this hand can win normally.

When the hand's closed section ''guarantees a specific yaku'', and the winning tile is not related to completing said yaku, the hand is never subject to atozuke. Even under rule #1, it will always be eligible to win.

*In this case, the hand has a closed hatsu triplet, so it can always win. Even if the hatsu triplet was drawn after the 789-sou call, there would be no practical way to prove you didn't have the hatsu triplet before calling. Therefore, "drawing yaku after calling" is allowed so long as you "complete" the yaku before winning.

*For whole hand yaku, like [[honitsu]] and [[chanta]], the hand's closed section is considered to have "guaranteed the yaku". Therefore, even if the hand didn't qualify for honitsu at the time of the first call, you can win with an open honitsu-only hand. (For a yaku like chanta, your waits still need to guarantee chanta to not be atozuke.)
