    across the world millions of timber frame structures are built every year, and many of them use OSB or CDX ply but definitely not marine ply as far as i know.
    screw the sheets down at 150mm centres on the rafters.

    OSB if the most common for this type of work.

    Marine ply is used on some high-rise flats/office buildings

    commercial work or civil engineering is not at issue here - "high-rise flats/office buildings" are not constructed with timber framing.

    you can if you want to but it is rather expensive (if you can find it)

    the felt is supposed to keep the rain off.

    you need to paint or seal all edges or it will warp and not last long.

    I have a house where the first owner was a boatbuilder and used it for built-in furniture, boxing-in, bath panel and so on.
