Okay:
Mass = 200g
Wing area ~110 sq. in.

Here's the fore-aft balance, suspended from the CG in the Tercel instructions. It's upside down, but still a little tail heavy.



And here's the left right balance after a repair to the wing attachment. It looks to me like the wing isn't on the fuselage square. I'm going to redo that.

That's quite a bit tail heavy.
Always error on the opposite of that. If it was nose-down that much it would probably glide, albeit fast.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !

I'm at ~9 oz.sq ft, when it looks like hand toss gliders are under 2. I wonder if it's worth trying to save.

Absolutely!
It will just set up in a fast glide, but you can still get an exceptional sink rate. Fix the tail heavy state, go slightly nose heavy, and it will fly.

Pitch/Yaw can be due to off axis thrust with regular rockets, and once I got my hands on a good DSLR I found that off axis thrust is extremely common. It might be a factor on rear engine boost gliders also, but probably not as much on a front mounted motor. After burnout, it would cease to have any effect anyway, and that's the majority of the ascent with most models.

The OP stated these were hand tosses.
It wasn't yawing under power.

10-4. I think I mention it would really affect his model anyway.

I did check to see if the earlier warp had returned, and it hasn't. The fuselage is still straight.

We're in for a few days of crappy weather, so I won't be able to make much progress for a while.

I'm thinking that I'll go out to the range on an off weekend and do a test flight before flying at a club launch.

Ok,
12g of additional nose weight and 7g on the right wing tip and I can get level, if not great, glides.

Hanging from the frame, she looks left-right balanced. I must have accidentally made the aerofoil unsymmetrical to have such a large left roll.

On to test launches.
