Contended RAW, What needs consensus Options

[WeaverMount]

I would like to come up with a list of things worth establishing when forming or joining a new game. On DS we get into a lot of arguments interpreting RAW. I hear people talking a lot about tables needing to establish not even a list of house rules, but an implementation of RAW. My intent is to gather enough data to list of everything that is worth stating to a new player about how your table works. What I would like your help fleshing out 3 lists:
1) Places where people could disagree about RAW, like how agents work
2) Common gentleman's agreements, like not using more interrupt actions than you have IPs per round
3) House rules common enough to ask about, ignoring Availability after char gen, or gymnastic dodge
While I'm sure people will get bent out of shape about what counts a RAW per usual, please take the actual arguing somewhere else. Remember if people disagree with you that makes the point contested EVEN IF THEY ARE WRONG. Synner said point blank you can't cast off of ultra-sound, but it's still worth it to tell people new to your table whether or not that will fly. I'll edit this post to keep the lists updated.

1 Contended RAW
How does edge refresh
Can unattended agents move to a new node
What response do agents use
Does cracking give you one or unlimited copies
How mobile are wards
Scope of Knowledge skills
Do wards protect a volume or a surface (especially in regards to direct spells)
The dice pools of "Average Joes" and "Typical Professionals"
What is a "set of wounds" for healing.
What can treat drain
Augmented Skill max
Brain Hacking
Targeting spells off implanted ultra sound or Radar
What counts as 'limbs' for the purposes of determining average attributes in the case of unbalanced cyberlimbs.

2 Gentleman's Agreements
No comlink haystack / 4 IP AR decking / Agent Smith'ing
Don't use your ally spirit as an infinite sustaining focus.
Don't be a script kitty
No using more interrupt actions than you have IPs per round
Don't spam great form spirits
Some kind of expectation about dice pool range

3 Common House Rules

What do Knowledge skills let you do (i.e. is Chemistry rolled in labs? does a demolitionist need Engineering(structural)?
