A ledger is a horizontal board that is attached to the top of the the wall.
A firewall is a fire resistive rated wall having protected openings which restricts the spread of fire and extends continuously from the foundation to or through the roof with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall.
The ledger is needed to properly attach the perpendicular roof trusses to the top of the structure.
To extend beyond the face of the perpendicular walls.

A firewall is an assembly of materials used to separate transformers structures or large buildings to prevent the spread of fire by constructing a wall which extends from the foundation through the roof with a prescribed fire resistance duration and independent structural stability.
Sheet metal caps offers products for posts beams fences roofs and flashing.
This allows a building to be subdivided into smaller sections.
Would expect that the beam should have a fire rating comparable to the wall it passes through.
