Eaves ventilation + panel ventilation

[Dede77]

Started work on insulating the garage and storage room.
Using 25x50 battens and masonite as an air gap (green + blue in the image).
The circled yellow area will be meshed to stop insects and allow air to flow in/out of the attic.

However, I wonder what I should place where the panel ends (red in the image)?
There will likely be insulation on top, so I want as little air in as possible while still allowing airflow behind the panel (right?).
Should I use wind barrier, plastic, or something else I haven't considered?

I would cut just inside the panel's air gap so the insulation only rests on the wall, not beyond the framework. The board should meet the air deflector.

Känns som en enkel lösning men hur håller det över tid?
