The Projective Dynamic Logo (PDL) is a foundational research programme that conceptualises physical reality as a network of minimally closed logical structures defined on finite signed graphs. Laubscher2026IntroPDL, Laubscher2026FullPDL Starting from four relational axioms and a coherence–optimisation principle, PDL yields a minimal (4, 6) stationary structure, interpreted as a prototypical electron, a hierarchical proton architecture with tightly constrained integer invariants, and a unified reinterpretation of several constants—such as, , kB, and an effective gravitational coupling—in terms of coherence ratios. This position paper does not present new technical results. Its objective is to synthesise the current status of the PDL framework, to clearly differentiate between rigorously established structural results, tightly constrained conjectures, and calibrated elements, and to formulate a concise set of open problems that delineate the next stages of the programme. Particular emphasis is placed on the implications of the dialogue with the Theory of Objectivity (TO), which has sharpened the modal and ontological issues underlying PDL, especially with respect to boundaries, multi‑observer stabilisation, and the interpretation of coherence leakage as a transcendent substrate.
