Clear pass for me. We're not making game unless p has an opening hand, and this hand is much easier to respond with than open. I won't open light unless I have a 5 card suit, and a rebiddable suit opposite any response. And rebidding ♦ on a FOUR card suit is not my cup of tea. As people have said though, with more texture in the suits, it might be worth upgrading to a 2NT rebid in which case opening is ok. Though I'll still probably pass.

Obvious 1♦ opener for me, any seat. Easy rebid if pard bids a major, and preempts opps out of their most likely fit, clubs. The only thing that can go wrong is PARD bidding 2♣ (as he did), but then you still have the contingency solution of 2♦ (which you used).

All in all, I think bidding was pretty good, although I might have chosen 1NT instead of 2♣on pard's hand.

If your agreement includes openings like that, your partner does not have a 2♣ response.

My agreements would include that hand, and partners hand would be a 1NT rebid. Leading to 1NT+2.

Pass for me, I hate 4441 hands, and would pass with 12 or 13 pts, unless very good 10s around.

Don't like your P's 2C bid, but as an Acol player, I'd have a dilemma how to respond.

To bid or not to bid depends on the sytem you play. Eg If you open 1♦ playing Acol 12-14 no trump, then North cannot comfortably respond 1nt with 10 points or even a good 9 and will have to respond 2♣. otoh playing 15-17 nt where no trump rebids show 12-14, partner can safely respond 1nt with 10 points and 2♣ with 11 upwards. (or 2nt playing 2/1 with 11ish) If you play 4 card majors and open 1♥ and partner responds 2♣, I think it is a distortion to rebid 2♦ which I would rely on being at least 5-4.

In short: no bid playing Acol, and 1♦ playing a 15-17 standard 5 card major system.

btw Playing 12-14 no trump and 4441 and in range with singleton A or K clubs I would open 1NT.
