Thanks again for the feedback! I was already mid-repotting session when I read Al's reply so I didn't incorporate any ballast at the bottom of the pot. Now I wish I had thought of that, or even thought to put a wick in the bottom of the pot. I made the mix I described above. The bag of orchid mix looked like it was a combination of fines or peaty soil and a lot of bark/sapwood. After adding the perlite, I think (I hope!) the net effect is something like the mix Al suggested above (using one part soil similar to what it's potted in already with two parts perlite). In other words, there's perlite, lots of bark, and some fines that are similar in texture to what the tree was already planted in. I watered to beyond saturation and held the pot at a 45° angle for a few minutes to let it drain even more. It drained really well, and the soil was definitely damp, not wet. It's on the porch now. It will get open shade for the first half of the day and full sun in the late afternoon. I've got a chair in front of the pot to keep it shaded for the first hour or so the sun is on the tree so it doesn't spontaneously combust. Thanks again for all of your help. I'll keep you posted if and when any new growth starts!

I haven't repotted, no. It's still in the pot from the nursery, which has drain holes. The surrounding grey pot in the picture is just a pot cover.

If I were Eve I'd start pruning that tree to be even more bushy! I've never been inspired by an F. lyrata before, but now I know that it's the tree-like like look that puts me off, because it looks more natural and healthy to me as a bush. But enough about me! Here's a great example of a thread with lots of advice on shaping F. lyratas into trees, and I'm sure you'll find some very helpful info if you spend some time browsing through the posts.

If you're located in the northern hemisphere, I would not repot this time of year. I'd wait until June 2018. Repotting: removing all soil from in and around roots, untangling roots and pruning roots. You need to give it a lot more light. The brown spots also indicate you are over watering.
