T
Time's Ran Out
It reads to me that the tiler has indeed done a well prepared floor and after 9 months + a few perimeter grout cracks is not a sign of poor workmanship.
If a crack appears in a mitred joint of a door frame would you get the decorator back to fill it?
You have a cellar below this floor, you may have increased temperature variation causing greater movement in the timber substrate.
Fill the cracks with the same colour grout with a flexible admix.
