Closer to 5 than 4? I think it is likely to be a standard M5.
Update: I got a set of bolt remover bits and things seemed to be going well - the bit was definitely biting into the hole of the barrel adjuster, then suddenly the end of the bit snapped off inside the barrel housing and now it's completely blocked 😆.
To make it rideable, I've mackled it so that the chain is permanently on the large chainring (rear derailleur unaffected of course) so it's usable to a fashion.
Not sure what to try next to be honest!

Is the barrel adjuster end accessible at all from the lower end of the boss?

Yep 'easyouts' are very brittle, that is why professional mechanics never use them. They cannot be drilled out (too hard) the only way to get them out is 'spark erosion'.
I'd try using a full covered cable to the front mech maybe with an inline adjuster.

Enough what showing?
Are you suggesting to cut a slit (green line ) in the housing to get the remnants out?
Edit....I understand you. You were suggesting to cut a slot in the end of the poking-out end of the shaft of the adjuster, then use it as a screw head to unwind it out. Unfortunately, there's nothing sticking out of either end of the barrel.

Depends on how drastic you want to be. You'd need to angle grind the existing cable stops off and replace it with one of these.

Thanks for the idea.
I'm not precious about this bike. I might get a Dremel and cut a slot in the barrel (green line in the photo). That might free the blockage and make the barrel still usable.
If that fails, your idea is a possibility.

Why would it need to be fully covered? Is that how inline adjusters work?

The stop on the frame is unservicable now,
I might be wrong - I don't think a covered gear cable could be routed around the bottom bracket, it'd be too thick.

I think you could add one of these to the clamp on cable stop suggested above and get your functionality back.
No reason to remove the existing one unless you want to for cosmetic reasons?

But I've never used any of these bits myself so caveat emptor!
