I was chewing over how a single stray bit of timing information can unravel an entire system. Have you dug into side‑channel attacks lately? They're a neat reminder that even the quietest leak can be a loud siren.

Nice sandbox, but remember a sandbox can still leak through cache line contention. Randomizing is a good first step, but always audit your timing sources; even a single constant‑time loop can betray you if someone’s sniffing on the clock. Keep an eye on the invisible footprints.
