How should I deal with a bowed joist prior to boarding

[crispy_wafer]

I have this attic truss, that while acclimatising and drying out has bowed somewhat on the bottom joist, wouldn’t be a problem, but…. It’s one that I will need to board over forming my stairwell.  My stud wall was plumb to the top of the joist, but the bottom 1/3 of it now bends out by about 5mm from the wolf plate towards the newel post.  The truss is doubled up, so I’d thought about taking the angle grinder with sanding disk to remove the offending timber.  Or I could Pack out all the studs to make good, which will be a ball ache and least favourable route.  Or would Double boarding, screwing the first and then dot and dabbing the 2nd.

 

I don’t know, how would this be dealt with in real life?

 

Thx

I would take a planer to it and loose that 5mm,, packing the rest WILL be a ball ache.
