FINAL authoritative version. Epigraphs translated to English; internal glossary annotation removed. No substantive changes. Abstract A — Philosophical TrajectoryThe present Triadic theoretical framework emerged from a sustained philosophical confrontationwith the limits of monolithic epistemic models in a world increasingly populated byheterogeneous intelligences—human, artificial, institutional, and hybrid. Classical theories ofmeaning, truth, and measurement presupposed a single dominant representational channel,typically electromagnetic observation interpreted through human cognition. Yet contemporaryreality exhibits a plurality of channels, agents, and inferential regimes whose coexistence cannotbe reduced without distortion.Relational Syntaxis (RS) reconceives meaning not as correspondence or reference but asrelational coherence across channels. Epistemological Special Relativity of MeasurementAgents (ESRM) abandons the search for absolute epistemic frames and instead studiesconditional invariants that persist across transformations between representational regimes.Epistemic Measurement Dynamics (EMD) completes the triad by recognizing measurementitself as an active epistemic force, shaping the informational geometry it probes.Together, the Triadic theoretical framework offers a philosophical architecture for navigatingplural representations without collapse, enabling coherence without domination, pluralitywithout relativism, and rigor without metaphysical inflation.
