I have a 10 year old shed for my lawn tools, that is 2X constructions,
with standard particle board siding. While the outside was painted
immediately, the inside of the siding was left unpainted. The doors
are basically a sheet of siding with 2x4 around the edge of each door
and in an X pattern in the bottom half of the doors . The doors
overlap the floor joist and come to the bottom of the floor joist.
The minimum clearance under the shed is about 8" and is open on all
four sides.

That area between the door and the joist has started to come a part
Since at this time the decomposition is minor, can i stave off the
replacement of the door by gluing the loose particles and painting
that are of the door?

Is there a better solution?

Treat with bleach/antifungal.Â* Stabilize with a wood hardener and
reinforce with filler.
I don't know if particle board/OSB is susceptible to dry rot, but it
does travel thru painted wood once it has begun.

Protect and paint the bottom edge of the particle board face well as
this is where the water runs down to, and pauses before dripping.
When replacing in the future, don't use particle board or OSB, even if
it is intended for outdoor sheathing. (it is meant to be enclosed by
other membranes.)
While it is not in direct contact with the ground, it is ground-adjacent.
