Granted it looks like fire damage, but how can I report it was if I was not around to witness it. If it does not leak and is structurally sound it’s off to the next step of my inspection. Let me know if that is not good HI practice.

I am fairly certain that I got the correct answer or at least the most popular, but, there will be some other questions later.
For now, it looks like there were previous leaks. It also looks like at one time, there were cedar shakes on that roof.
That may be a local thing to my area.

Going only from what is visible in the photo, I believe my "real life" answer would be... "Some fire damage noted to original skip-sheathing. This does not appear to have significantly affected the structural rafters. 7/16" OSB sheathing has subsequently been applied and appears to be in good condition. No action indicated.
This looks more like a total re-roofing with a different material than just a "repair". Obviously roofers have been clomping aroud up there to install the new roof sheathing and covering. I see no signs of cracking or damage from that. I just don't feel this requires FE.

Looks like the top edge of the rafters are burnt, too. Wouldn’t that affect the strength? I would report that there had been a fire previously. If there are other signs of past fires in other areas of the home, I’d note them in the report too…

OK, OK…“Uncle!”
In person I would be poking and prodding this area with my screwdriver to see if it was more than superficial. Is the "notching" in the middle third? I can't tell from the photo.

Somewhere I read that if the “charring” is less than 1/4" deep than the integrity of the member is not compromised. I’m trying to find where I read this.

Aha!
From Carson Dunlop Home Reference Book:
Structure:
12.0 Mechanical and Fire Damage
..... As a very general rule of thumb, major structural members with less than 1/4 inch of char do not require resupporting. This, of course, depends on the size, orientation and function of the member. Where there is doubt, specialists in this field can be consulted.
Sounds like a gut call to me. Difficult to answer without being able to see the adjacent members. But, going by the picture alone, I say C is the best answer.

The more I look at it, it looks like the osb is actually filling several gaps around the stringers. If that is the case, the main beams may be compromised.
If this was a recently re-roofed structure, I would want an engineer to come out and certify the roofing structure as being sound.
On the roofs that I have seen that were previously shake and then tile or shingle was added, they either removed the stringers or the filed in the stringers and then went over them with plywood.
The damage is still present and I would call it out for further evaluation.
