I know the NEC requires clear space in front of a breaker panel.
What depth of wall change would violate this? My basement, where the panel is, has a 6" jut where the block wall becomes timber. So from where your toes are against the wall, the panel is 6" deeper, as the wall depth changes.
From the side (black line is the floor), it's like this:
The flush panel is in the framing above. There is also framing below.
All walls are finished properly but because of the construction the panel door is six inches deeper from the edge of the floor.
I am fine with the 30" horizontal clearance.
How should I interpret the clear space requirement in NEC in this situation? Am I required to extend the top half of the wall out to keep it entirely flat and bring the panel out to that the new depth?

The NEC's clearance requirements are for the safety of people working on equipment once it is installed.
With that being said the NEC width requirement is a minimum of 30", and the door swing if there is one minimum is 90 degrees. However your panel does not have to sit in the center of the 30" it can be moved from side to side.
Reading you question I can't determine whether you panel is against the block wall and the wall depth change is 6" and runs the other direction at that same depth at least 30" or there is just a recess that the panel fits in and it is recessed in an area less than 30". So with the first situation the panel is fine and with the latter, it needs to be brought out to meet clearance.
Also I don't know if you are speaking about a horizontal recess and the panel is mounted below the block wall. Most AHJ will allow 8" before they consider overhead being an interference.
Hope this helps
