Partner is also aware of my bidding proclivities in that situation, and alerts it so that the opponentstakes it into account.

FYP.

No alert. 3 card minors are considered natural in the ACBL, so, in fact, you messed up my post. Don't ever do it again.

Natural bids are alertable in the ACBL if they have a highly unusual or unexpected meaning, at least according to my understanding. I suspect this would be regarded as highly unusual for the majority of club players.

This does not have a conventional meaning. Its a non-forcing natural bid. And, in the ACBL, 2C is frequently used as a non-forcing natural bid with only 3 cards. I think you are wrong, but I invite you to take it to a vote in the laws section if you want.

How can 2♥ show six over a 2♣ response? You have to bid something with a Flannery hand.

Of course it shows six over a 1-level response. Not as a general principle, though. After 1♦-1♠ you can rebid 2♣ on a 3-card suit* but after 1♣-1♠ you may be stuck.

*I do that also but I am not sure it is actually a good idea. Probably it should depend on the quality of the diamonds. Anyway, playing strong notrump you can also rebid 1NT with a singleton in partner's suit.
