1♠: Good start
2♣: Good response, no matter what parameters you have for a 2♣ call.
2♥: Good second bid
2♠: Makes sense -- show support with support. Of course, many of y'all play that 2♠ might just be a doubleton, a waiting bid, I think. So, maybe 2♠ shows support, or maybe not.
3♣: This works for all styles. However, knowing the style dictates what Responder will expect.
If 2♠ was a waiting bid, with two-card support, then 3♣ presumably completes pattern without agreeing spades. It might also logically be a COV doubleton, with absolutely no help in diamonds (maybe 5422 with a strong doubleton club?).
If 2♠ established spade support, but pattern is King, then 3♣ seems to show the 5413 pattern but says nothing about the strength of the hand (six loser with shortness in the right place) nor of the wildly useful club contribution.
If 2♠ established spade support, and if 2NT denies good trumps (gratuitous plug), then 3♣ shows at least the club Queen so far, nothing about shape.
If 2♠ established spade support, and if Aces-first is used, and if shape is secondary or not completed, then Opener has the Ace.
So, 3♣ is right, no matter what that means.
Back to Responder and 3♥.
If 2♠ did not establish spades as assuredly trumps, then perhaps Responder should now bid 3♠ to clear that up. However, maybe a cue does that. I have no familiarity with the clarification stage for the "could be waiting" theory.
If 2♠ did establish trumps, and if 3♣ was a pattern bid, then 3♥ is right whether we are using Italian cues or Aces-first cues. However, only in the first case is the diamond hole identified.
If 2♠ set trumps, and if 3♣ showed good trumps and a club card, then 3♥ is right, as showing a heart control but no diamond control.
Finally, if Opener used Aces-first cuebidding without any shape bids, then 3♥ is right.
So, 3♥ is right under any theory except if 2♠ did not guarantee a fit AND 3♥ carries forward the mystery. The 3♥ call sometimes sends a message about the diamond hole, but sometimes that hole has already been covered by the pattern bidding (if pattern bidding was used by Opener).
Now to the 4♠ call.
If 2♠ did not establish a fit, and if 3♥ did not either, then 4♣ seems wiser. But, again, I'm in uncartered and unknown waters with this theory. If 3♥ made 2♠ no longer ambiguous, but clarified the fit, it seems that Opener should emphasize his great club contribution, as he only showed xxx before.
If 2♠ established a fit, and 3♣ was pattern, again Opener should clarify the A-Q nature of his three clubs.
If 2♠ established a fit, and if aces-first is used without pattern bidding, then I'm not sure what Opener does next -- again in unknown waters.
If 2♠ showed a fit, and 3♣ showed good trumps with a club card, and then if 3♥ isoltaed the diamond menace and showed a heart control, then Opener seems to have a clear call of 4♣, showing the diamond control by inference, having already shown two top trumps, now showing a second top club, and inferring by bypass of 3NT that he has nothing to contribute in hearts (hence, describing his hand completely, for all necessary purposes).
Whew.
General observation -- guessing how someone else bids in these auctions is extremely difficult. It would be good for people to at least agree on a general school of thought as to slam auctions. However, even stumble bunnies would not have bid 4♠ with Opener's hand.
