This is a two step solution. The first part succeeds or fails deterministically. If the first part fails the fallback comes into play and that succeeds or fails probabilistically, so you may need to generate a pseudo random number to evaluate this proposal.
Part 1: this part uses partial transfiguration and his newly practiced skills from the 6th year textbook.
Harry must transfigure something touching his wand, so the object transfigured is a small patch of skin touching his wand. He will probably lose that bit of skin when the transfiguration wears off, but this should be acceptable and non fatal.
The object he transfigures the skin into is as follows:
A minimally thin thread (maybe a carbon nanotube) going down to the ground, the the thread continues along the ground to the time turner.
It then goes through the space in the hinge / snap of the shell into the interior of the shell (the thread may have to get very thin to accomplish this, but the case is described as snapping into place in chapter 18, so it is not truely seamless).
Once inside the time turner shell the thread splits into two strands one wraps around the inside of the shell, thickens to be sturdy and attaches itself to the inside by transfiguring sticky bits. The other wraps around the time turner itself thickens up and then attaches itself by transfiguring some sticky bits.
Lastly various rods or threads extend to push / pull the inner ring vs the outer ring. Since we know that you can transfigure against tensions this will allow Harry to rotate the time turner inside its shell without the outside of the shell moving (we know from Azkaban that this works).
Once the time turned has been turned, Harry will jump back in time by one hour since the time turner is being held by Harry’s hand and turned by his hand (the thread is a part of Harry’s finger that’s been transfigured).
Once Harry is alone in the graveyard an hour in the past he has escaped the immediate danger and has time to plan.
Advantages of this plan are that it involves no visible motion of any kind. Partial transfiguration is wordless, and his hand is already touching his wand. The thread is too small / thin to see, and the macro part of the transfiguration happens inside the time turner’s shell where it is not visible. The evidence in the book this far is that transfiguration time is gated by the volume of the target, this is a low volume transfiguration so it should be quick. The other advantage of this plan is that it’s non interactive. It doesn’t involve talking with anyone, penetrating shields or otherwise rely on interactions working out a particular way.
Fallback plan—part 2: if for some reason the above doesn’t work (and it should work, but it’s always good to have a plan B) Harry should decide that now is the time to free the prisoners of Azkaban, and in his innermost emotional core reach out to the Phoenixs of the world asking them to teleport him to Azkaban.
Harry turned down his choice so he will never be master of a Phoenix like Dumbledore was, but a Phoenix might still help him. Faux helped Hermione when she wanted to be a hero even though he wasn’t eligible to give someone a choice at the time. So we have evidence that a Phoenix is capable of helping someone outside of that context. We also know that a Phoenix can remotely detect the intent to help a problem or even the strong consideration of helping. So a Phoenix would be capable of detecting Harry’s choice to free the prisoners, and it would be capable of teleporting him there, and it might want to.
So then the question is, will a Phoenix want to help, so far we’ve seen 2 and both birds seemed interested in the Azkaban problem, but it’s probably a biased sample.
Let N be the number of in universe Phoenixs. The author knows or can estimate this number as the creator of te universe, I’ve got no clue.
Let P be the probability that a given Phoenix would decide to help Harry save the prisoners by teleporting him to Azkaban. Again the writer knows this number better than me, but I think the textual evidence suggest it’s non zero.
Then the chance of success is (1-(1-P)^n) since it’s an or relationship, fail is the AND condition of each and every Phoenix individually choosing not to help. If the author has not previously determined value functions for each and every Phoenix then the best way to evaluate if this plan succeeds is to use God knowledge to estimate P and N and then generate a random number.
I note that although the long term life expectancy of someone teleported to the heart of Azkaban may not be great, it would technically meet the exam passing condition of evading immediate death. That said, step 2 is mostly a last ditch effort that relies on some luck, if it were my life, I would be relying on part 1 to save me.
At least one other person has suggested stating plainly, in Parseltongue, that the optimal way to kill Harry would be to send him to Azkaban and let him kill the dementors. If that doesn’t kill him, then continue with the previous plan.
I doubt this is in fact the safest way to dispose of Harry, but it might be possible as an extra idea to gain time.
