I'm actually pretty happy with the joseki result here. White has one group sealed in the corner and has a floating group without eyes to worry about. Black is stable on the top and has options with the left group.
White has sente now.
I wouldn't be surprised to see white put pressure on my left-side group here before approaching the bottom left. If white approaches first at a/b/c I will play a long pincer at d to help stabilize my left side group.

Closer than I expected white to come in at, but my response is the same. Black needs to avoid being sealed in.
If white tries to cut...

No problem, I disappear from time to time as well.

Not for the players:
Isn't Aphelion missing the following?

I can't imaginee that Aphelion would plan on
as shown above, for it clearly does lose. I suspect that he is looking at the following:
$$Bc

But white can force ko, I think:

Click Here To Show Diagram Code [go]$$Wc Black cannot play a or b.Black appears to be ahead in the liberties race, but he cannot play either 'a' or 'b' immediately, so he must fight the ko. White has ko threats at 'c', 'd', 'e' and 'f'. Black has ko threats at 'g' and then 'h'.

Black at G has no teeth. Ko is illusory.
But, unfortunately, in Aphelion's first read through, he did miss this line. However, since it is
clearly a bad play for black, I suspect we'll see the atari underneath, and pushing from behind, which, while painful, does fix the weak group problem.

Oh crap I think I misread badly:
$$Wc Uh oh...
Click Here To Show Diagram Code [go]$$Wc Uh oh...I need to think about how to deal with this now. W7 at 8 seems to be the strongest resistance, but I need to be 100% certain it works before playing it. It doesn't look good now...

White has chosen to seal me in. I'm okay with this because white has little profit and no moyo.
