Saved, owner of the Speedrunning discord, has just confirmed that the Figure Closet Glitch is allowed in runs. (if I put "[ ]" around something, it means Im not sure about that detail)

The way to preform the Closet glitch, based on what I've seen, [is to spam Q/E when the heartbeat minigame begins (but not when the heartbeats get too close to the middle, causing you to fail it)]. Once the figure is stuck in the animation for the closet, aka when the hearts reach close to the middle in the heartbeat minigame, you are generally safe to hold W and leave the closet (I've died from getting out too early). Keep in mind, you might still have to press q/e even when you're out of the minigame. I advise to walk around to the sides of Figure rather than through him as he might still have his hitbox [as others can still walk into him during the closet minigame and die].

So, with being able to lock Figure into the closet animation while we're able to run freely about for a few seconds, would this be viable anywhere as a new Speedrunning strategy?. I have a feeling it could work, but the best solution I'm seeing right now is avoiding figure altogether.

In my most recent video, around the 2 minute mark, I made an accidental discovery. Ambush was coming to get me, and as I entered into the thin narrow hallway, I realized there was no other area to escape to

I hid behind the opened door in the small corner and found out that Ambush wasn't able to kill me there.

If this works for Ambush, this could work for Rush too, and can potentially save a lot of peoples runs in a niche situation. I can post a link for anyone who wants to check (if that's even allowed in the forum board)
