Partner deals and the auction goes:

1♣ -(pass)- 1♠ -(2♦)- pass -(pass)- ?

Playing support doubles Partner has denied three ♠ as the agreement in effect is to always show support.

What do Responder's bids mean here? How light should one reopen? When should Responder pass?

If vulnerability matters please discuss how it impacts the situation.

Any advice is appreciated.

Thanks

I play that non-reverse balances in this situation at the 2- or 3-level are nonforcing.
So 2♥ would be NF here.

X is take-out and only to be passed with a good 4-card holding.

X+bid is forcing except for a preference to the opening suit and invitational raises of partner's reply to the X.
So if partner takes a double out in 2♥ then 3♣ & 3♥ would be NF and everything else is forcing (game bids are not, of course). I don't have any short minor openings in my system, but if 1♣ could be three, then I think responder's X->3♣ should probably be forcing.

Direct jumps are forcing. (I play 2♠ as invitational and 3♠ as forcing because of WJS, but others might play 3♠ as invitational).

Some of all this is nonstandard.

The strength requirements for a competitive move should depend on the shape. With a 5-5 in the majors, for instance, one could bid 2♥ with much less than it would take to double 2♦.

2H, 2C are NF, double is takeout and doesn't show extra strength. 2NT natural invitational, 3D and 3H force to game, 3S invitational.
