Explanation
The count. This post is draw 24 of the companion run:
new Random(546395639), Next(10,35) per post. The RNG predicts N = 13;
the post has N = 13 ✓.
The seed is the machine's uptime in ms when the app started (boot 2016-01-13 11:18–12:18).
The body. Not decrypted: the key is not recovered. What has and has not been tried on the run's bodies is on the companion account page.
