I'm sorry but you continue to talk nonsense.Nobody, not even a DIYer would loop the neutral and spider the live from a junction box.
The live will be looped at the switches.
If you continue to pursue your nonsense about it being switched neutral, please explain how there are several neutrals at the light fitting? there would only be one if it was a switched neutral.
I wouldn't call it nonsense Dave, a possibility based on a permanent live.
If indeed the live is permanent, as the op has stated, then the neutral is switched.
So you explain to me how if the lamp has a permanent live, how else can it be switched other than through the neutral?
The op describes himself as a Electrician, id expect him to whether the live is being switched or not.
And as i said, im not disagreeing with you or anyone else, just a possibility based on the provided information.
You may well be right, i may well be wrong, i don't really care, but if the op is correct and the line is permanent, then its neutral switched. Its an alternative possibility, and if you think that's the worst a diyer is possible of, i would disagree lol
