Conventions ....

You folks will know this convention better than me - apparently the 3♦ was showing top of the range in spades. What should the director's ruling be?

There are two schools that I know of for the answers: 3♣ and 3♥ show a weak 2 in hearts, 3♦ and 3♠ show a weak 2 in spades.
The difference between the two schools is whether 3♣ and 3♦ show a weaker or a stronger hand (and of course 3♥ and 3♠ the opposite).
So depending on agreements 3♥ show 6 hearts with either 6-8 or 9-11 HCP while 3♦ shows 6 spades with either 9-11 or 6-8 HCP. (Their HCP ranges can of course be slightly different).
And BTW.: I see no reason for the Director to take any further action at all in this case! Law 25B2 has been correctly applied, and while Law 26 is applicable on the cancelled 3♦ bid (showing spades) there will be no lead restrictions (in case North/South should eventually becomes defenders) as spades is legally shown by North with the 4♠ bid during the auction.

Second, assuming the ruling that 25A didn't apply was correct, has South used UI? We can't tell without the actual hands. South knows from UI that North has a maximum weak two in spades, not a minimum weak two in hearts. The UI clearly suggests bidding over passing, since bidding will get you to 4♠ rather than 3♥, and partner has spades not hearts. So is passing an LA opposite a minimum weak two in hearts?

Let's say that 3♦ shows a max with spades while 3♥ shows a min with hearts. South has to pass if she has an invitational hand since she can't use the information from the 3♦ bid but if she has a clear GF hand then 4♥ is fine.
North knows that she has misbid (that knowledge she apparently came by herself so it is AI) s she is allowed to correct to 4♠.

South may bid 4♥ if she holds a hand with which she would bid game regardless of which major suit North has, for instance if South has 4+ - 4+ in majors and something like 18+ HCP. South may also bid 4♥ with a weaker hand which has significant distributional values opposite 6 hearts (weaker subrange) in North.
If, however, South raised to 4♥ apparently based on the UI that North (probably) has 6 spades then adjusting the contract to 3♥ in North might be in order.
(In my previous post I assumed that South had a legitimate raise to 4♥)

That will make Multi very uneconomic, particularly when 3♣ and 3♦ responses to 2NT are used to show the stronger hands.
Just imagine the auction:
2♦ - 2NT
3♠ (showing 6 hearts and the lower HCP range). Now it is impossible to land in 3♥.
I use 3♣ and 3♦ to show the lower HCP range maintaining the transfer effects in such cases. It is less important to have the Multi opener becoming dummy when he has the stronger (weak) hand.

Was english the first language of the player involved ? I could imagine playing in France wanting to bid 3♣ and writing down 3C then rapidly correcting it to 3T. Or was this done with symbols ?

Forgetting your agreements doesn't make it an unintended call. At the time he wrote 3♥, he intended that as his bid because he was under the mistaken impression that this showed spades.

Yes, Helene is arguing that it probably wasn't an unintended call.
My first reaction was to think it probably was unintended, though, since I wasn't familiar with the method where 3♥ shows spades. Now that I am, I see how it could easily be a 25B case.

Surfe it does.
And how do you bid over your partner's Multi opening when you have a strong hand so you expect a fair chance for at least game except if partner happens to have 6 hearts (even with as much as 11 HCP). In that case you reckon that there will be only 9 tricks.
This is a typical situation for the 2NT query knowing that you will never be forced above the three level with a disappointing answer.

There are lots of different schemes of response to the multi, some of which depend on the strong options. Certainly a lot more than "two schools"
For example,
3C shows any range with spades (over which 3D asks for range, responses 3H min 3NT max- NT declarership has already been decided; 3H is natural 5+ cards FG)
3D min with hearts, 3H max with hearts (over which 3S is natural FG)
3S+ depend on your strong options
there are more
