I’m hung up on 1S interference. It could be the case of “too many bids”.
Like if I want opener to declare NT and search for a 4-4 heart fit then
1C(1S) dbl P 2N P 3C P 3S? Or 3H?
If opener lacks a spade stopper but has 4 hearts and wants to GF then
1C(1S) P 3H?
But there’s 1C (1S) dbl P 2S which would deny a stopper and could search for fits up the line....including hearts
And 1C (1S) dbl P 3S probably is undefined whereas 1C (2S) dbl P 3S would be.....I don’t actually know that either because opener could just force with 3C, 3D, or 3H here (if he had either 5 or if he had 4 with no stopper).
Would you please explain how you continue 1C (1S) dbl?

I actually don't think we have any complicated agreements in this auction. Perhaps something very simple like:
Pass = five-plus good spades
1NT = natural like 17-19
2♣, 2♦, 2♥ = minimum, 4+ suit, not forcing
2♠ = game force not sure of strain (basically a catch-all for GF hands not suited to higher bids)
2NT = game force with spade stopper, may also have some interest in a suit contract (even may have four hearts)
3♣, 3♦, 3♥ = game force, five-card or longer suit (basically sets trump although 3NT is still possible after a 3m bid)
If opener bids 2♠, responder's first responsibility is to bid 2NT with a stopper. The 2♠ bid is usually balanced without a spade stopper, but some two- or three-suiter is also possible.
