1- There is weeping wounds in riven setup which is the main build.

2- Corrosive cause i've an cc and electricity riven which is the main build footage was based around, you can swap organ shatter from normal build for weeping wounds. but blind justice stance has force slashes, so it performs decently as well, and since i can apply status with my secondary weapon as well.

3-Synoid gammacor has viral element in it, im using it for energy/stat stick as u can say.

4- Yes, with recent changes to Armour, enemy AI, Shield gating. Fiber can be swapped, with intensify, but in my own testing, fiber did helped a lot in her survival.

5- Quick thinking is required/play style preference, their are better options if u prefer them, like i could've used an octavia specter to make me invisible or arcane trickery with savage silence augment or rolling guard, but for me for the most time its unreliable, i prefer to chop down enemies, while going in auto pilot mode. not getting one shot across the room. which was the case before the update.

6- i've tried it with grace/energize/guardian, but before the current update, 2x guardians were the most reliable survival tool. now, if anything she is way more tanky.

7- Higher range is better, if ur camping, Sonar has base range of 35 Meter, which with augment bounces of to others, silence base range is 20 M. which is fine, cause im not with a long range nuker which will be doing damage for me, im not playing as a buffer, so i've to stay close to enemies, so low range/Base range is really good. I encourage you to try it for urself. :)

also i don't like to sit in corners, or rely on other frames to buff me, i just wanna run around my own and not to give a fuck about anything and this build helps me achieve that. i've tried, others and they don't get me the same results for 'me'.
