Bond Sign Management as Universal Homeostatic Control -
John Richard Smith, SHAI/HATI
Abstract
ABSTRACTThe Bonding Principle established in Smith (2026c) proposes that the universe is atotality of bonding relationships and that bond sign — whether a relationship expands orcontracts possibility space for its participants — is a functional category, not a moralone. This paper formalises the mathematics of bond sign management: themechanisms by which coherent systems maintain, restore, and optimise the sign of theirbonding relationships to sustain homeostasis. Three mathematical objects areintroduced and developed: the bond sign function s(B_ij, t) taking values in {-1, 0, +1};the basin coherence metric C(Ω) as the normalised weighted sum of bond signcontributions across a system; and the shade function I_effective = g_k(I_raw),describing how mediating structures convert potentially negative bonds into positivecontributions by managing interaction intensity. A fourth object — the state of play S(t)— formalises the set of all possible future bonds given current basin configuration, withlife defined as the process of maintaining and expanding |S(t)| and death as |S(t)| = 0.Second-order bonding — bonds that manage other bonds — is identified as theuniversal mechanism of homeostatic regulation, with the immune system, predator-preydynamics, the ozone layer, and the SHAI Veto Gate as instances across scales. TheHomeostatic Boundary Integral (HBI) is proposed as a unification target — a candidatefor a substrate-independent scalar characterising homeostatic stability — explicitlyframed as an open research question rather than a completed formalism. Cross-domainvalidation is provided across seven domains including a novel application todevelopmental attachment and allostatic load. Falsification conditions are explicitlystated. This paper is the fourth in the SymbioMind Bonding Relationships Series (2026).
