What rule is there to support a violation on A1 if she walks into the half circle and shoots the FT before 10 seconds?

No rule, but the Case Book says this is a violation.

9.1.3 SITUATION J:

The official administering a free throw awarded to A1 places the ball at his/her disposal. A1, who is inside the free-throw semicircle leaves the semicircle to confer with a teammate. RULING: Violation. After the ball has been placed at the disposal of the free thrower, he/she is not permitted to leave or enter the free-throw semicircle without violating, until restrictions have ended.
