Ive read in a few places that when you finish all wzi levels, you can reset them. I recently stumbled uton the term 'to ascend' after finishing all levels, as opposed to replaying them.

What really happends when you complete all wzi levels? Can you replay everything for full AP?

Real

When you beat all levels, a button appears at the top that says “Ascend”

It resets all levels (you have to unlock again), but you keep all AP upgrades, items, Artifacts, and Challenges.

You can replay everything for full AP indeed after ascending. However, the powerups on each level (time warp, free cache etc.) are limited to two times each; that is if you claim a time warp the first and second time you play a level, you won't get it the third time, even if you ascend between the second and third time.

do the levels get harder to scale with what you bring to it?

They don't get harder when you ascend. I'm on my third run and I now complete them way, way faster than I did before. I think it'd be a good idea to let players who've ascended a few times play an advanced mode. Time might pass 1/5 as quickly for 5x the AP reward, for example.

I'm working on my 2nd run through. And certainly the playthroughs are much quicker the 2nd time through with all the extra AP advancements and artifacts.

How close are you to unlocking phase 4?

I unlocked it Saturday. I can make a thread with the details if it's no longer considered a spoiler. I haven't spent any AP in it, yet.

If you've unlocked it, it's fair game. That was made clear in a thread ... link I can't find right now.

Actually you've already posted it so moot point. (;
