This job isn't imminent and I like to have a good understanding before hand if what I'm going to do, shouldn't do and what I have to make choices about.
Fair enough, but do remember the unknown-unknowns problem if you DIY. If all you do is to ask about the things you know you don't know, you run the risk of not asking about things you don't know but have no idea that they exist and you do need to know them.
Indeed - and that, of course, would be a reason for none of us to ever doing anything, since there is always the possibility that we don't know that we don't know something important in relation to the task!

The task is so complex that the amount to know exceeds the ability of any individual to cope.
The person carrying out the task had elected to not learn the finite and achievable number of things which were widely regarded as necessary by authoritative sources.
The person carrying out the task was not capable of learning the ditto.
.... The person carrying out the task had elected to not learn the finite and achievable number of things which were widely regarded as necessary by authoritative sources.
'Electing' would not come into it if the person did not know what (s)he did not know about "the finite and achievable number of things which were widely regarded as necessary by authoritative sources".
My apologies - I thought I had explained it clearly enough for anyone to understand.
2. The person carrying out the task had elected to not learn
the finite and achievable number of things which were widely regarded as necessary by authoritative sources.
In other words, they decide to not find out what they should know.
It's fairly unlikley that anyone (including you and I) could ever be absolutely certain that there were no things that they should know that they didn't know that they should know.
Paraphrased as, ' don't be wilfully ignorant' perhaps?
So, on topic again.
A radial circuit, around the rear of the stud walls, clipped to the rafters, above the insulation, buried in earthed metal conduit where it crosses the gable wall would be a sensible way to do it.
It's fairly unlikley that anyone (including you and I) could ever be absolutely certain that there were no things that they should know that they didn't know that they should know.
Take several books by reputable authors on things like C&G 2357, 2382, 2394, 2395, on domestic wiring techniques, IET Guidance Notes, the OSG, Electricians guide to the Building Regs, explanations of the Wiring Regulations and so on.
Read them, cross reference them, come to understand what they are telling you.
In short, do not elect to not learn the finite and achievable number of things which are widely regarded as necessary by authoritative sources.
