When an instructor endorses a logbook with a limitation and the student
violates that limitation then the specific section of Part 61 that the
endorsement contained is reg broken.

As for Part 91, that depends on what the pilot (student or transition) did.
91.3 addresses the PIC responsibilities (which a solo pilot, student or
transition, is by definition). 91.13 is for careless or reckless operation.
Once again, it depends on the circumstances and how much the feds want to
write up.

glider training is not a student pilot.

Correct, and precisely my point.

As another poster noted, a CFI gives authorizations and may limit them
as he
or she sees fit. Operate outside that authorization and you violate
Part 61
and possible Part 91.

Really? Exactly what part of Part 61 or 91 will you be violating if
you are not a student pilot? Chapter and verse please.
