Well, the mechanics can be seen first-hand indepenendly of the code by testing it, in particular this has an impact on a recent official competitive format as it enabled Terapagos into a reliable answer to Shadow Rider Calyrex.
Indeed, although as is, I feel like there needs to be something establishing the immunity nearness stuff for Tera Shell as more than "mechanics", & something in lore would be nice.
& you know that GF is big on making their mons VGC viable.
That's more so to encourage players to keep playing every now and then, which is also part of why there's Mystery Gift events as well as changes of rules for official competitive formats every now and then, this is common for games with post-release content these days.
What I'm advocating for is Tera Stellar Arceus being a cheap way to adapt to most Tera Raids supporting on the existence of a Terastallized Arceus not being an ignorable thing from the development side of things, thus if there was a desire to more accurately prevent it from Terastallizing it'd be the case.
I think they didn't prevent Arceus from Terastallizing not because they're trying to establish lore or anything, but to support raids & because all Pokemon can Terastallize regardless.
Arceus presumably can Terastallize in lore. IDK why it wouldn't be able to.
We have yet to see Arceus overriding a Terastallized type change to itself with Multitype in the first place. In particular Multitype doesn't protect from other methods of changing type such as Soak, while Terastallizing does. Creating something does not inherently include having better control over it for a particular purpose.
Does Arceus not have other type control feats, like granting the powers of the types through the plates?
I'd wanna hear the opinions of others on this matter.
Oh, I meant that from the game mechanics side, sorry for going on a tangent. Frankly I don't think this stuff is of much use as it's simply vague as said before.
I guess we'll tackle the behaviour of Tera Raid Pokemon later?
for the scaling, I presume you mean the way to scale Gen 9 characters involving paradoxes scaling to Champions, then Nemora (a Champion) scaling to Red by fighting each other in Masters, who basically has a scaling chain leading to Cyrus, thus 2-B paradoxes, Gen 9 legendaries and so on.
IIRC, there was supposed to be an interview quote about Masters was supposed to have the games be canon to it, but not Masters canon to the game.
& in this case, besides, not sure I personally, care for it, since it seems to mostly just turn a consistently tiered scaling chain into one that goes to 2-B by cross-continuity scaling, & to a mobile game no less.
Anyway, quoting an old post of mine:
Jacq says that, thanks to protagonist, "our" (who's?) investigation, & their new data says Terastal energy is released from the Great Crater of Paldea "from time to time", which affects Tera Crystals - Tera Crystals hit by "especially strong blasts" of this energy become "black crystals". Tera Pokemon found at black crystals are "incredibly powerful", Jacq emphasizing such with
"So much so that average Trainers wouldn’t stand a chance against them." & urging the protagonist not to take them on, even if they do find the location on their map app.
After the player completes one, Jacq calls & says
"We just saw the Terastal energy reading from one of the black crystals disappear a moment ago. Do you know anything about that?!"
Jacq is surprised the protagonist succeeded, & says, among other things:
"Your efforts have helped us come to understand the laws governing Terastal energy emissions."
"Still, even after all this, it seems that the amount of energy being emitted is slowly growing."
"That means we may continue to see more black crystals appear in the future."

Put another way:
You need to see the credits to participate in 5 Star Raids. Meaning become Champion. AFAIK, that means clearing The Way Home; Beat the AI Professor.
Beat 15 5-Star Raids, & he warns the player character about 6-Star Raids, asserting that
"You're anything but average, but I'm afraid this is too dangerous—even for you, <player>.".
Beat a 6 Star Raid, Jacq is shocked, glad protagonist is okay, & urges them to be careful, even saying
"Ah, by the way, Director Clavell will be madder than a rampaging Primeape if he finds out, so let's keep this between us two!".
It's clear that even for Post-Champion-Rank trainers, 5 star raids are dangerous, & 6 even more so, such that a student apparently can't normally be permited to attempt them.
To say nothing of what that implies for 7 Star Raids.
Still, if nothing else, Tera Raid Pokemon can take on 4 at once, & are grouped by level, though I'm unsure if the levels are meant to be known.
But 1 5 Star Tera Raid Pokemon being equivalent to 4 Champion Rank Pokemon, a 6 Star Tera Raid Pokemon being superior, etc.
& that's just in the base game; The Academy Ace Tournament implies the Pokemon get stronger, at least through dialogue & Pokemon levels.
Which brings up the question of how much stronger they are; For example, Nemona's Pokemon team are implied to be stronger for the tournament; Does this apply for her Mochi Mayhem battle? The Blueberry Academy Battle?
Levels & dialogue suggest it, no?
It will also help to figure out Area Zero Scaling, since these at-the-time, near Champion Rank Trainers return & fight Paradox Pokemon, then later, a different group -Impleid to be stronger, because Blueberry Academy & power progression- goes down & battle Tera Stellar Pokemon.
The Paradox Pokemon are concerning because that might be a basis for scaling a whole subgroup. IMHO, it's our best bet, since they're fairly direct showing.
(Also, Glimmora, but it was early into Area Zero. Maybe on that level of power but lower?)
