Hi. Good questions. I've attempted to answer all of them with footage except for the Unaware questions this time around.
<snipped multiple quotes about Outrage's confusion affliction effect>
I checked first-turn outrage into a Fairy switch-in, and the Outrage user was not confused afterwards. Not sure how OP was testing, but I wouldn't put too much stock into raid testing since the raid mon can use moves into allies, so things aren't as clear.
I've also confirmed that
the initial use of Outrage won't cause Confusion when attacking into a Fairy-type. Outrage appears to work as it has since the introduction of the Fairy-type, at least in the current version of Scarlet and Violet as of writing this (v3.0.1). Everything appears as normal.
It's possible something was broken in an old game version, or as ralts_boy proposes, perhaps something was weird with the Tera Raid conditions of the interaction previously messing with turns or similar. I'm afraid I don't know enough regarding the Tera Raid mechanics to be able to say definitively.
Can anyone check the interaction between Neutralizing Gas and Mold Breaker on cart with these abilities, like whether the users cure themselves of status similar to Water Veil. For example, Neutralizing Gas Weezing burns Garganacl with Will-O-Wisp, does Garganacl cure itself once Weezing switches out?
ralts_boy pretty much covered this, but I'll pitch in too since this section was already written.
Mold Breaker and Neutralizing Gas both allow you to apply status to a Purifying Salt target.
Purifying Salt will not cure a status affliction once it's been applied, even after Neutralizing Gas leaves the field.
Thermal Exchange will cure Burn as soon as it's able.
In Mold Breaker's case, this means that immediately after using, for instance, Mold Breaker Will-O-Wisp on a Thermal Exchange target, Thermal Exchange will activate to cure the Burn before other moves happen on the turn.
In Neutralizing Gas's case, this means that Thermal Exchange will cure the Burn as soon as Neutralizing Gas leaves the field, before other moves on that turn. For instance, NGas Weezing switches out and goes into the Pokeball, then NGas plays its deactivation message, then Thermal Exchange activates to cure Baxcalibur's Burn, then the next Pokemon enters the field.
Do future moves incur Life Orb damage immediately? They currently do on PS.
Future Attacks
do not incur Life Orb recoil until the attack lands. Life Orb's damage boost and recoil are not applied if the user of the Future Attack is not on the field at the time that the attack hits its target. Life Orb's recoil and damage boost will still apply if the user swaps out and back in after setting the Future Attack, such that the user is on the field when the attack hits its target.
However, this
seems to be correct on Showdown since 2021 or so according to GitHub. It's possible that you saw an old replay before this was fixed. I'd propose providing a recent Showdown replay showing the issue if you still think something is broken with this interaction and we can definitely do more testing.
Do multihit moves immediately stop when the subsequent hits change type? (So a Pixilate Tail Slap against a Ghost-type with Mummy or Wandering Spirit)
Pixilate-boosted Tail Slap does not cease mid-attack when attacking a Mummy Ghost-type, even though Pixilate is removed by Mummy after the first hit. The first hit works as you'd expect a regular Pixilate-boosted attack to work. The subsequent hits appear to remain Fairy-type attacks, but do not seem to receive the additional 1.2x damage multiplier from Pixilate.
I believe this was known already in some places like some Hackmons circles, plus it seems right in the damage calculator. Still, it's nice to have footage of it in the modern games to verify everything remains correct.
Can a Hoopa-Unbound/Darkrai transforming into another Pokemon use Hyperspace Fury/Dark Void and vice versa?
Hoopa-Unbound cannot use Hyperspace Fury while it's Transformed into a different Pokemon, but a different Pokemon can use Hyperspace Fury while Transformed into a Hoopa-Unbound.
Footage here.
Darkrai is exactly the same with Dark Void: Darkrai cannot use Dark Void while it's Transformed into a different Pokemon, but a different Pokemon can use Dark Void while Transformed into a Darkrai.

Does Infernal Parade/Hex's BP double against Comatose?
Yes.
The power of Hex appears to be increased when attacking a Comatose target.
Hope this helps.
