Shot put is not a throw, and the rule book is fussy about the difference. World Athletics TR 33.1 says the shot is put from the shoulder with one hand only, that it touches or sits close to the neck or chin when you take your stance, and that the hand never drops below that position during the put. The shot also cannot go behind the line of your shoulders. Everything else that gets called is about the circle: the top of the toe board, the ground outside, the sector lines, and which half of the ring you walked out of. The implement has to pass inspection as well, which the legal shot weights by level covers.
Bracing hard against the inner face of the stop board is exactly what it is there for, and TR 32.13 permits it. The top edge is not yours. World Athletics counts the top inside edge as part of the top, so a spike that rides up over the lip on the block is a foul even though you never left the ring.
One minute from when your name is called, under the World Athletics field event table in TR 25.17 and under NFHS 6-4-3a. It starts before you pick up the shot. Chalking, taping and pacing behind the ring all burn it, and letting it run out is charged as an unsuccessful trial. Long jump runs the same one minute rule, listed among the ways to scratch in what is a foul in long jump.
Glide and rotation both finish with the athlete facing the sector, so stepping forward is the reflex. Your first contact with the top of the rim or the ground outside has to be completely behind the white line drawn through the centre of the circle. First touch is what counts as leaving. The equivalent exit rule in the pit is explained in how the long jump is measured.
Nobody feels their hand drift behind the shoulder line or their foot brush the top of the toe board. Film one throw from behind the ring and AI flags the frame where the put stopped being legal.

Run these in order. They are the same checks the ring judge is running, in the same sequence.
You may enter from any direction, and you may touch the inside of the rim and the inner face of the toe board on the way in. Before the put begins, both feet must be still and in firm contact with the ground inside the circle. NFHS 6-4-3b makes failing to pause a foul.
At the stance the shot touches or sits close to the neck or chin. The hand does not drop below that position during the action of putting, and the shot never travels behind the line of the shoulders. Cartwheeling techniques are banned outright by a note to TR 33.1.
One hand only. Slinging it, bringing it from behind the head or releasing with two hands is a failure under TR 32.14.1 and NFHS 6-4-2. This is the rule the whole event is named after.
Once you have stepped in and begun the put, touching the top of the circle rim, the ground outside, or any part of the stop board other than its inner face is a failure under TR 32.14.2 and TR 32.14.3. The top inside edge of each counts as the top.
The sector is 34.92 degrees and the lines are out. If the shot touches the sector line or the ground outside it on first contact, the trial is dead no matter how far it travelled.
Stay in the circle until the shot has touched the ground. Then your first contact with the top of the rim or the ground outside has to be completely behind the white line running through the centre of the circle.
