The negative double obviously needs the strength to handle the level of Opener's rebid, so I don't think Opener's 3-bids need to be forcing. After 1M (3H), for instance, Opener with spades can bid 3 or 4 spades confident that Responder can handle either --pass, raise, or correct. With a monster, we still have the 4H Cue at Opener's disposal.

You can select more than one.

1m - (3H) - Dbl - (Pass)
There are a lot of weak notrump type hands where opener is sort of stuck rebidding 3NT. If opener actually has four spades that is basically the best possible news. Usually a 4-4 major fit is worth an upgrade, especially since most of the minimum doubles are hands with singleton heart where you feel compelled to act in order to protect. So it seems weird that opener's 3♠ rebid (great news! we have a fit!) is not forcing to game, whereas when opener doesn't have a fit you are basically compelled to play 3NT.

It's not necessarily great news. What would Opener rebid on a 3=2=5=3 shape with xx in hearts, say AJx xx QJxxx AJx? Pass? 4♦? 3NT? I think many people would bid 3♠.
Also, whilst Responder would like to have 4 spades to double, but he's not always dealt the ideal hand.
Finally, it's worth remembering that if Responder does have an ideal shape for a double, he may have stretched to enter the auction in the first place. Does this mean that when he has to choose between 4♠ and defending 3♥?

Partner and I play 1a-3B-x to facilitate a 3N bid but not require it. Partner can always pass for penalties.
We've decided that after 1a-3♥ any action by responder forces to 3N or higher (4 card ♠s are implied but not guaranteed).
1a-3♠-x does not guarantee ♥ but does guarantee the strength to play at level.
The issue I find with the question is a negative double implies tolerance and no fit - so a GF is not technically established.
Trust demands integrity, balance and collaboration.

Well, quite, so this is why it doesn't need saying. All discussions of methods work on the assumption that you will have agreed the method with your partner.

If you, however, can double 3♠ with much less hcp and perfect shapes and/or with hearts+diamond hands where you think you have a safe heaven in diamonds even if you were not actually expecting to make your game necessarily vs a dead minimum by pd, but close, then even though you kinda forced your pd to game, will it create a FP or not is debatable.

Kryztof Martens are proposing that the double in this sequence is negative with four ♠, or a game going hand without a stopper in ♥.
After the double 3♠ is forcing from opener, and responder can then bid 3nt to show no 4 card ♠ and no stopper in ♥.

This is interesting. But how do the partnership find a spade fit?

So what he is saying is, DBL of 3♥ is GF regardless ? Because he says it is GF w/o ♥ stopper or negative double with 4 card spades but must be GF also because he suggests 3♠ by opener is GF. Since he does not tell how to stop in 3♠, DBL of 3♥ must be GF regardless.
Or did i miss something ?

I don't think you missed anything. 3S by opener apparently can't be passed, and 3NT after that by Responder is not likely to be passed either, since NT would be wrong-sided. Sounds like if opener has XXXX KJX AQJ JXX, he might bid 3NT instead of 3S out of fright.

cant partner have the values to compete to 4 of minor but is unable to force to game and doesn't have a ♥ stopper
if opener has extras and fit you'll find 5 of minor
same with 1♥-(3♠)-X?

This seems like a natural progression from Thrump Doubles to me. Another reasonable approach with a similar effect would be for double to show 4+ spades and 3♠ to be a stopper ask + some strong hand types.
