Sorry, I don't quite understand "pin inspection bar"?

Is this all assembly layer? If so, do you think the assembly layer arrow
should point upwards on the SMDs? The IPC assembly layer arrows don't
extend beyond the body line.

The silk screen is put so it can be seen after soldering. The ASCII art
arrow is an assembly layer feature, modelled after the IPC standard.

Agreed, even with the IPC-style silks, I think the arrow has extra value.
