The Swan notes are pretty quiet on this situation. It seems pretty obvious to me that partner has the 11-13 bal hand for his pass. The notes specifically say

1♣ (pass) 1M (DBL); RDBL shows 3-c support and either a good 11-13 or 17+.
OK, so we are playing non-mandatory support redoubles, can I extrapolate that we are also playing non-mandatory support doubles in this auction? Seems they might have mentioned it...
Anyway, I'd like to bid a natural, invitational 2NT here, is that what partner should take it as? But it seems we will potentially miss a 5-3 heart fit, is there a solution?
