If we're discussing what the responses [i]should[/i] be, it seems pretty clear to me that 6♠ should be the worst, not 6♣, that the responses should get worse the higher they are (to 6♠).
I would look to the Bridge World series Useful Space ...
With screens (only) or without? During the auction is what "alert" implies, was that what was meant?
"This demonstrates active ethics, even though not required by the regulations."
Is this a suggestion that those who don't aren't actively ethical?
"Observe that over 1♠ - (2/3♦) ?, the other minor would be clubs bid at a higher level and so the switch cannot apply."
My recollection is that when I played switch, it was only in effect after a black suit overcall.
Without discussion, I would assume setting trumps (a hand that would have jump-shifted if playing strong jump shifts).
A picture bid is a fine agreement, but requires agreement. Likewise, setting trumps and asking for key cards -- fine, but only with agreement (or meta agreement).
