This paper introduces and formalizes a decisive kill condition for that entire corpus: The Straight-Line Boundary Statement: When a domain reduces to analytic, closed-form, non-recursive solvability—when no entropy expansion, attractor stabilization, watcher regulation, falsifier search, or constraint recursion is required—the bridge language must terminate. If invoked in such a regime, it is decorative. This boundary is not rhetorical modesty. It is structural self-limitation. It enforces the anti-replacement commitments of A Bridge Language Is Tested by Load, the authority and scope constraints of SCOPE & GUARDRAILS, the killability discipline of Multi-Platform Linked Public Building as a Cognitive Strategy, and the instrumental (non-ontological) claim class of Critical Self Critique — The Full Triad. A framework that cannot die in trivial regimes is already broken. ⸻ 1. Introduction: Why a Kill Condition Is Required The corpus establishes a constraint-first recursive epistemology whose job is narrow: • Detect generative instability. • Apply constraint pressure. • Prune counterexamples. • Stabilize identity under entropy. • Prevent replacement and authority drift. In KEY PAPER TO MCPHETRIDGE RECURSIVE EPISTEMOLOGY AND BRIDGE LANGUAGE, recursion is framed as a model-honesty mechanism under pressure. In A Bridge Language Is Tested by Load, replacement is defined as the central failure mode of cross-domain vocabulary. In Thought Forms Epistemology (The McPhetridge Thought Process), deduction is shown to emerge only after recursive falsifier elimination. In Uses of Executable Frames — Here’s a Tiny Universe. Run It., frames are killable runtimes, not metaphysical universes. In The Information Substrate — A Knowledgegraph Operating System and Language, constraints, operators, watchers, and admissibility modes are execution primitives. In Seed Myth — A Minimal Regrowth Handle for Constraint-Bound Systems, minimality and removability are survival tests. In Φ-Method; A Self-Study in Recursive Epistemic Engineering, the method is stress-tested against itself under recursive load. In Constraint-First Engineering as Epistemic Method — A Solar Flash-Boiler Rankine Engine for Vacuum, real systems are defined by constraint ceilings, not ideal cycles.
