Five classes

Water flows where hydrology, gravity, climate and infrastructure carry it. Need is where bodies are. Patterns that reconcile flow and need without degrading the cycle sit inside the region. Aquifers drained past recharge, rivers moved at rates the ground cannot sustain, systems contaminated past absorption — outside it. The present pattern is substantially outside.

Food grows where soil and climate permit and is eaten where bodies are. Production concentrated where the soil cannot sustain it, soil depleted past regeneration, populations starving while others discard — outside. The present pattern is outside.

Land is finite. Every human and non-human architecture runs on it. Concentration on provenance-failing histories, displacement, contraction of non-human conditions past sustainability — outside. The present pattern is outside.

Energy is generated where physics permits and used where work happens. Coupling past absorptive capacity, access denied to those whose lives require it, cost pushed onto those the energy never served — outside. The present pattern is outside at the resolution Chapter Ten read.

Knowledge is produced where conditions allow and propagates at C. It is non-rival at coupling: my reading does not shrink yours. Restriction that tracks neither production cost nor risk, access concentrated at historically advantaged classes, suppression that contracts the room without justification — outside.

One clarification on knowledge. Non-rival at coupling does not mean free to produce or open at every site. Production cost is real. Safety risk, privacy, dual use and cultural authority are real. Restriction that tracks those is cooperative. Restriction that blocks coupling while tracking none of them is parasitic.

Finance is not a sixth class here because Chapter Four worked it. At planetary scale it allocates access to future capacity. Where it widens cooperative coupling, cooperative. Where it locks the already-narrowed out of the future while concentrating buffer at the already-wide, parasitic.

Medicines, shelter, minerals, digital infrastructure, transport — the same test by the same geometry. You run it.

None of these flows was invented by an authority. Each is substrate plus coupling. Align with the flow and the room widens. Oppose it and the room narrows.
