Speaking about the structural integrity of a 2023

Has anyone seen this kind of failure in the cabin area below the chain plates where the rise in the cabin top meets the outside deck?

The picture is from my 2023 and isn't really from below the port side chain plate, but from above the bulkhead forward of the chain plate that defines the start of the V-birth.
Some years ago I noticed similar damage at the forward edge of the shelf and filled the gap with thickened epoxy. Now I find the re-filled epoxy has broken...

This makes me think that the cabin top is gradually being pulled apart by the force of the stays pulling on the chain plate. There is no similar failure visible on the starbord side, but that is more strongly supported by the wall of the head. Also, there is no sign of a problem from the outside..

What to do?????
I have been thinking about sandwiching the bulkhead that defines the forward edge of the shelf support with a piece of angle iron on the shelf side and flat iron on the cabin side, through bolted in several places and with an extension welded to the angle iron for attaching a turnbuckle. Then I was thinking of using a stainless steel strap attached to a couple of the chain plate through bolts to attach the other end of the turnbuckle. I would then take the mast down to remove all stay tention, refill the cracks with epoxy and see how much I can pull the cabin top down while the epoxy holds. I would leave the turnbuckle in place permanently to help transfer the load from the cabin top to the rib that is tabbed into the hull. There is about 10 inches from the bottom of the chain plate to the top of the shelf.

Better ideas?? Anyone seen similar problems??
