coming from north until about here GR76, Chemin de Compostelle and d'Asssise follow the same route. GR76 then turns right.

regarding the markings on the road the way of st James goes this way to the bridge

This is an isolated dwelling - there should be a landuse=residential around, not just farmland.

On the ground in the very center of the tower is a triangulation point. Since I don't know if the mapped tower or the mapped triangulation point are more exact I just write this note for people which know the whereabouts better.

here is a path with steps (see uploaded log)

Around here - the first driveway to the west on this part of D94 - is an organic farm with a shop open from 16:30 on vendredi.

Check if this highway exists and if yes: how it crosses the railway. Bing Imagery doesn't show much helpful things.

Somewhere around here is a building which a hut not open to the public but with a quite extended roof which serves as good weather shelter.
