this is the code from persistent.sfs, Who can explain the meaning of each line

[The Aziz]

Well most of them are self-explanatory, aren't they?

pid - ID of that vessel
name, type are obvious
sit - current situation, landed, in orbit, suborbital etc
landed is true, duh, when vessel has landed
landedAt probably tells the body
splashed is true when in water
met is MET, mission elapsed time.
the next two are probably also related to time, where UT is in-game time since the save started
lat-itude
lon-gitude
alt-itude
hgt, nrm, rot determine the orientation of the vessel
CoM is obviously Center of Mass
stg is current stage
ctrl - my guess is it's true when you have control over your vessel
lines inside ORBIT{} are just orbit informations, semi-major axis,  eccentricity, inclination, longitude of periapsis (I think), longitude of ascending node, mean anomaly, epoch, reference number of orbiting body and its name

the rest that I didn't mention - no idea what they mean.

Do you know the full names of "hgt, nrm, rot "?

 

[The Aziz]

Can't tell much about hgt (wiki describes it as height, but that makes no sense here) I mean I think I've seen this before but no idea what that one means. Maybe how high you are when on the ground, and -1 appears when in flight.
nrm is normal, rot is rotation?

Create a backup of the original. 

Change a value in the test version.  

See what it does. 

Restore the backup after the craft goes poof. 

 

And btw, those aren't codes.  Those are variables and their associated values.
