Are Shadow Assassins proficient with Sawtooth Sabre?

In RAW, how proficient is the shadow assassin with the sawtooth sabre?

Weapon and Armor Proficiency
A shadow assassin is proficient in all simple weapons, all light weapons, as well as bolas, net, repeating crossbow (light only), shuriken, spiked chain, and whip. The shadow assassin is proficient with light armor and small shields, but not heavy shields or tower shields.

Sabre, Sawtoothed Category: [light] Proficiency: [exotic]
A sawtooth sabre may be used as a Martial Weapon (in which case it functions identically to a longsword).
If you have the Exotic Weapon Proficiency (sawtooth sabre) feat, for the purpose of two-weapon fighting you can treat it as a light melee weapon; for all other purposes, it is a one-handed melee weapon.

Here’s scenarios we’ve been discussing:

  1. SA can not wield SS proficiently, since the SS is an [exotic] weapon.
  2. SA can wield SS proficiently, but cannot use it as a [light] weapon due to lacking the Exotic Weapon Proficiency feat.
  3. SA can wield SS proficiently and as a light weapon, since the SS is a [light] weapon and SA have proficiency in "all light weapons".

Can I wield a Saw-tooth Sabre with my tail as a Ratfolk using the Versatile Design weapon modification while being a Red Mantis Assassin?

I started playing a Rogue Ratfolk and have brought myself to the RMA prestige class. I used to wield a ratfolk Tailblade to maximise sneak potential, but it didn’t work out because the attacks kept missing so I abandoned this idea. However after a year of playing I suddenly discovered weapon modifications from Advanced Armory.

The Versatile Design feature says that weapons with such a mod can be treated as a different weapon fighting group with the limitation of converting melee weapons to range (which does not matter in this case). Although, it can be changed to the Natural weapon group, which contains ‘tail’ I suppose.

I can apply Weapon Adept and Exotic Weapon proficiency granted by the feats I already have. Moreover, I would also apply Weapon Focus, Greater Weapon Focus, Weapon Specialization and Greater Weapon Specialization granted by the Red Mantis Assassin class.

I have Amulet of the mighty fists with Agile enchantment as well, so applying Dex to attack rolls with natural weapons is not a problem.

So now I’d really like to return to idea of three-weapon fighting but I’m having a sort of confrontation about whether I can make this combination with my GM.

Would having Versatile Design on a Sawtooth Sabre allow me to wield it on my tail, therefore having my tail weapon benefit from all the feats granted by the Red Mantis Assassin?

Building blockchain application step-by-step for Hyperledger Sawtooth for total beginners

I have seen many beginner to advance articles on Ethereum blockchain development like Blockchain-as-a-Service Apps Using Ethereum and Quorum and Ethereum Blockchain Application Dev with Java and Web3J API

Below is good for Hyperledger but not Sawtooth https://coding-bootcamps.com/ultimate-guide-for-building-a-blockchain-supply-chain-using-hyperledger-fabric-and-composer.html

However, I am looking for similar articles for Hyperledger Sawtooth. Any suggestion? Online search gives me links mainly to documentation
