State & bounds
A position, not a verdict
Your day resolves to coordinates in the state space — a bounded region within which a living system can still organize and recover. The reading is where you sit inside it.
The science
Membrane Health computes your state against a formal definition of health, calibrated to your own physiology. Here is the whole picture, layer by layer — from the human idea, to the mathematics, to where the proofs live.
Layer 1 · The human idea
A living system stays itself by organizing what arrives — load, timing, recovery — and holding its shape while the conditions around it change.
Health is whether that organization holds. A cell keeps its shape with a membrane, a living boundary that flexes and stretches but only so far; your whole body works the same way, on a larger scale. Membrane Health reads whether the organization is holding today, and how much room is left before it can't.
Layer 2 · The mathematical object
Underneath the daily reading is a formal object: a state space with defined bounds, relations that play out through time, and a region that counts as healthy. Your reading is a position in it, measured against that region and calibrated to your history.

Your day resolves to coordinates in the state space — a bounded region within which a living system can still organize and recover. The reading is where you sit inside it.
Defined quantities
Coherence, stability, recovery, and capacity are defined quantities in that space, not metaphors — which is exactly what lets them be measured and computed rather than guessed at.
Layers 3 & 4 · at Fieldflux Biosystems
The definition itself, the machine-checked corpus, and how the proofs can be independently verified live at Fieldflux Biosystems — the company behind Membrane Health. Formal verification establishes the integrity of the mathematics; physiological validation establishes how its measurements behave in people.
Layer 3 · The computation
Deterministic, relational mathematics — no black-box AI. Every result is a defined function of its inputs and can be replayed exactly from the record. The platform →
Layer 4 · The proof & evidence
Over 560,000 lines of machine-checked proof — what Lean verifies, what physiological testing validates, and what remains research, laid out plainly. The science at Fieldflux →
