Yes, I understand that part, that's my understanding as well. But the key is that the 1 stop underexposure is "burnt" into the RAW (unlike cameras settings, which don't report 1 stop underexposure), together with (totally guesswork here) some flag that later instructs that a different tone curve is applied during processing. Of course you can develop RAW as you like.

Normally, HTP applies only to the jpeg file. I don't know, it could be that there is a flag in the raw file that directs Canon DPP to develop the raw file differently by default. But it should still be basically the same raw file.

yes, the HTP is of course directly visible in jpg. But the raw file must have different exposure settings than a raw file with HTP off.

Yes, if it shows ISO 200 for example, it actually sets the ISO setting internally to 100, and gives you 1 stop less exposure.

The differently exposed raw file, combined with an HTP raw developer curve give the HTP effect when done from raw. That's why I think there must be a flag somewhere. Perhaps it's even embedded in the same flag(s) as the "picture style" flag curves

I don't want to keep repeating this, and it's quite beyond the scope of the original question--unless the OP still has questions.

Except for reducing the exposure, the HTP setting should have NO effect on the raw data. If there is a "raw developer curve", it must consist of a direction for default development of the raw image, since you can develop the raw photo any way you want: with or without HTP.
