I'm building my first Starfinder character and I want to be playing an Android rolling around in Heavy Armor with (at least) Longarms that is also a knowledge/skill monkey type character. For whatever reason, I'm into smart guys with big guns.

With that, I keep going back and forth between two ideas and I'd like your help making a firm decision. I'm torn between:
Scholar Exocortex Mechanic taking Skill Synergy for Culture/Mysticism
Blitz Soldier 1/Technomancer X with the requirement of Versatile Spec.

Any thoughts? Pros/Cons? I know casters shouldn't dip and I can take feats and whatever, but I think I'd rather just pick up the 3 free feats (Heavy Armor, Longarms, Heavy Weapons) for the 1 level dip, especially as more of a weapons guy than full caster type.

Does the 1st level ability of Armor Storm Soldiers mean that you threaten with your unarmed strikes, since they're considered Battlegloves?

Hammer Fist (Ex) 1st Level pg 113:

How does the Shadow Oracle's Stealth Mastery Revelation function in Pathfinder Society play?

According to Additional Resources:
"The shadow eidolon (page 11), shadow oracle mystery (page 12), shadow bloodline (page 16), shadow psychic discipline (page 17), and shadow blessing (page 17) are legal for play."

With no clarification on whether specific revelations are legal or not, it leaves this specific revelation available. However, the 8th level part of that revelation is:
"At 8th level, you gain Signature Skill (Stealth), even if you don’t meet the feat’s prerequisites."

However, again, according to Additional Resources:
"Skill Unlocks: the skill unlocks and Signature Skill feat are only available through the rogue's edge class ability."

Does the Stealth Mastery Revelation grant an alternate feat in place of that part of the ability, does it not give anything at 8th level, but retains the other parts, is it a specifically not legal Revelation at all, or does it supersede the Additional Resources restriction?

Does the Living Grimoire archetype's Holy Book feature work similarly to a Wizard's Bonded Item for enchanting as a Magic Weapon, treating the Inquisitor as having the relevant Item Creation feats, or is it just clarifying that since it is being treated as -not- an improvised weapon it is just capable of being enchanted? Additionally, does counting as a Cold Iron Light Mace also mean that it costs more to enchant, per Cold Iron weapons?

It's fairly obvious that this is intended to be a Swashbuckler focused prestige class. However, it seems as though a pure Swashbuckler won't actually qualify for the prestige class unless they (fairly uselessly) take the actual feat Weapon Finesse, since Swashbuckler Finesse only counts as Weapon Finesse for feat prerequisites.
Is this intended, or an oversight?

Quick(ish) question on legality of something:

Are Spireborn Half-Elves allowed as an ethnicity? None of the half-elf ethnicities in Bastards of Golarion are called out as legal, but ethnically restricted traits are called out as legal with some exceptions. That leads me to believe that the ethnicities are allowed. The ethnicity doesn't change racial stats or traits in any way, but does change the languages to Azlanti and Elven rather than Common and Elven. I know in the case of Tien ethnicity humans, they are given Common as an additional language for PFS despite Tien ethnicity replacing Common with Tien. I'm just super confused as to whether I can actually have the ethnicity. I don't want to take any crazy traits or use it to qualify for anything, I just want it for flavor. I can also just take Azlanti as a language and say I'm a Spireborn without having it on my character sheet, but I'm weird and particular.

Thanks!

Can a Mindblade Magus use his or her Psychic Pool to create a Technological weapon such as a Chainsaw or Monowhip?

Sidebar, not specifically rules related:
If so, is this legal for PFS?

The archetype Blade Adept gives an Arcanist a sword which is treated as an Arcane Bond and (eventually) a Black Blade.

Does this allow the weapon to progress as a Black Blade normally does AND add additional enhancements at half cost, per the Arcane Bond rules?

Are the various Half-Elf/Orc Ethnicities listed in Bastards of Golarion legal for play? Additional resources states that racial traits are legal if the character matches the ethnicity but does not clearly state those ethnicities are legal. In contrast, Human ethnicities are listed out as being legal in the Inner Sea World Guide entry of Additional Resources.
