This paper proposes that continuity, conservation, symmetry, and variational structure can be treated as methodological constraints governing admissible evolution in physical and engineered systems. Rather than introducing conservation laws only after a model has been constructed, the present approach enforces conservation behaviourally at the level of system description. This leads to a general framework termed Dynamic Behaviourism, or Conservatio Continuum. The framework begins from a primitive continuity relation and develops a generator-based structure for admissible evolution, closure of conservation sectors, symmetry constraints, and variational selection. From this basis it yields a methodology for modelling, prediction, and control based on symmetry-aligned observables, lifted linear predictors, variational feedback laws, and explicit diagnostics. Chronoflux is treated as a compatible temporal symmetry sector within this wider methodology rather than as a separate theory. A rigid-body attitude example on SO (3) is included to illustrate the modelling and control pipeline, but the emphasis of the paper is methodological rather than application-specific. The central claim is that conservation may be enforced as a structural condition on admissible behaviour, providing a coherent route from first principles to implementable system design.
