The PSR, the Ur-Fact, and the Triadic Ground_Why the Principle of Sufficient Reason Converges on a Triadic, Non-Coercive Ground

This paper argues that the Principle of Sufficient Reason, followed past the point where the standard cosmological arguments stop, does not terminate in a brute fact, an infinite regress, or an unexplained necessary being. Applied to the minimal fact that determinate being obtains, the demand for sufficient reason generates two structural requirements for any adequate terminus — unconditioned actuality and internal explanatory sufficiency. Joined to a further requirement drawn from the wider Agápēic Relational Metaphysics series (the necessity of grounding genuine otherness without coercion), the argument yields a third requirement: non-coercion toward what proceeds from the ground. The wider series independently identifies the structure satisfying all three as triadic and non-coercive. This paper is explicit about what it establishes on its own resources (the route from the rationalist demand to this constraint-profile) versus what it imports with citation from the wider series (the exhaustiveness of the four failure modes and the triadic minimality of the surviving structure).
