In the last one day, I've read through this topic - all the 29 pages, yes. First of all, it's very nice to see someone who knows what he does, and can go near the limits. Thank you g-force for your commitment and hard work - and everyone else's work you based your script on.
That's quite some feat. Thanks for the kind words.

1. Levels() causes clipping in the video, burning out some details in the brights spots (perhaps even in the not-so-bright spots).
Levels, if used incorrectly to increase brightness, will cause clipping of the whites. I am not using levels in this way.

2. There's some halos around the edges; try YAHR() to reduce them. If you find YAHR's strength a bit too high (losing details), try increase sharpening first and stop right before the halos appear again. If you don't like to result, you may want to use supersampling. Anyway, you'll see what YAHR() does and if it improves your video or not. Probably yes.
Already tried most of what you have proposed. The problem with YAHR (and to some extent even better de-haloers) is that they kill corners and small lines, and leave the video with a soapy, artificial look. One of Didee's poorest products IMHO. I'd be interested in looking at some specific examples if you want to actually try them on the GOUT and post what configuration works for you.

3. From the screencaps I have seen there seem to be a very slight chroma problem.
Could you be more specific about what chroma problems you see?

If it's a smearing similar to color bleeding
No, it's not. See Mielr's explanation above.

If it's like fieldblending (that means the trails are coming from the neighbour frames - the smearing led to four-eyed startroopers)
No, it's not even close to that either. And that is not what led to the four-eyed "STARtroopers". ;)
The smearing is from a form of noise reduction that is VERY similar to a weighted TemporalSoften(), except using only previous frames, and not having much if any scene change thresholding. This will NEVER (yes, you can quote me on this) be removed from an automatic filtering technique. The major problem is that the filter applied was extremely non-linear. It affected dark scenes more, and can have affects from between 0 and 5+ frames previous. Yes, you read that correcly, I have seen frames that have remnants from at least 5 of the previous frames.
