Your defence to a Multi (weak two in either major, with or without a strong option) is a simple one that your partner prefers:
P then X of 2M/3M = t/o, 10-14(15)
X = 15/16+ any, not suited to 2N or 3M
2M/3m = NAT, 11-15/16
2N = (15) 16-18 BALish, suggests stoppers in both M
3M = 14-17, good 6+M (the kind of hand that would make a NF jump rebid after 1H-1S)

Given your agreements, what is the meaning of this auction
(2♦) P (2♥) P
(2♠) 2N
where 2♥ is pass or correct and 2♠ shows a weak two in spades?

Would the meaning be different if you were using a different defence to a Multi?

The meaning of delayed action might be

• 2N = ms.
• 3m = ♥ and bid m,

minors

I see 2 possibilities:
- minors
- like an immediate 2NT, but with only a stopper in opener's suit (in your example only a stopper ♠, no ♥ stopper)

Since that hand would immediately Dbl according your agreements, only minors is left.
