The inner rubble stone is not stabilised at all, in fact there's a void in many places The wall has never seen any lime mortar before. It's just dried mud.
Realign stone wall?

Only my opinion but that bulge may well be historic and not likely to move any further.
Personally I'd point it up and see if the new pointing cracked at all - and only then consider other options if it does. If you push the wall back there's no guarantee it will stay there......
It's a great job you are doing!

Yes, Burmerman, I think it is historic, I think it's been like that for the few years I've been coming here.
I'm not convinced that cracking is a particularly good indicator of further substantuial movement.
I've rebuilt a whole corner of the same building a few years ago, and there's zig-zag hairline cracking more or less betweem the joints of the rebuilt bit and the original part.
When I rebuilt the corner it did look dangerous and in danger of collapse, plus it was close to the BBQ area.
I used 20cm X 20cm X 50cm blocks for an internal column to rebuild the corner, then faced it in stone. I added reinforced concrete filling down the holes of the concrete blocks, which I had laid in alignment, so I don't think that is moving any where.
I'm not yet decided whether to leave it, try to realign it or rebuild it. I know what I should do. The historian in me tells to leave it, the perfectionist in me tells me to rebuild it, and the pragmatist in me tells me to try bashing it back into line.
I'm going to have to come to terms with my multiple personality disorder before I decide.

If I could give multiple thanks, that one deserves it! Brilliant idea, Stuart!
I think I've seen a car repair type hydraulic jack in the workshop, with its many add-on tools.
It'll probably need topping up with hydraulic oil, but I suspect I can find some of that around as well.
I was worried about some of the stones disappearing into the wall completely.

Well after trying to jack some stones back into line with little or no success. I've taken down some of the wall, and I'll rebuild it.
Some stones wouldn't budge, I can imagine the amount of weight of stone on them from above. The wall is about 3 metres high, and the bit I'm working on is the lowest 1.5 metres.
Some stones moved so easily that it moved all the cob mortar with it, leaving the stone ridiculously loose afterwards.
If I'd conrtinued I would probably have lost about 50mm in the cumulative height of those stones, and I'd have to remove them anyway to reset them properly.
I'l probably take a few photos as I'm going. It never ceases to amaze me how much stone comes out of a wall like that, and how much time it takes to take down a small section of wall carefully. I reckon I've also cleared away about a metre cube of cob mortar.
I've been at it for a day now, and I'm just at the point where I have to continually clear out the soil and cob in order to see and remove the last few 'courses', and that's just the outer skin, but a fair amount of middle rubble invariably comes down as well.
I think it's like painting a masterpiece. The trick is to know when to stop.

I said I'd post a few pic's on progress:
Made a start.
Load of rubbish falling down
Degree of bulge obvious. Water dripping off roof was falling on the bulging wall.
After 2 days finally ready to start rebuilding.
A couple of liberal doses of diluted PVA to stabilise the remaining a bit.
Flung some lime mortar to stabilise the remaing some more.
Start of 7th day. But I've had a few half days: errands, other jobs, weather. There's about ½M³ of sand and 2 bags of lime used so far.
I've intenionally scraped the mortar out of the joints to give me something to point into. But I do like that look.
