Buffered Byproduct Regime Shift: Deceptive Stability, Buffer Slack, and Regime Reorganization in Earth-System Transitions

Gabriel John-Toussaint DuPree 

Earth history includes episodes in which biological or geophysical processes generate persistent byproduct loads whose early effects are partially masked by environmental sinks and buffering pathways. This paper synthesizes established literatures on Earth-system revolutions, redox transitions, mass extinctions, and
Anthropocene change into an explicit phase grammar termed Buffered Byproduct Regime Shift (BBRS). BBRS frames transitions as sequences: (A) emergence or amplification of a persistent load, (B) buffered accumulation during a Deceptive Stability Interval, (C) sink strain and declining buffer slack, (D) threshold crossing and rapid background-state reorganization, (E) selective mortality among specialists of the prior regime, and (F) reorganization and radiation under the new baseline. The framework thus includes both a
destructive half, centered on buffered disequilibrium, slack depletion, threshold crossing, and selective mortality, and a generative half, centered on reorganization and the expansion of pre-adapted strategies under the new baseline. BBRS does not propose a new physical mechanism. Its contribution is comparative: it treats buffer slack as a variable for cross-case analysis and the interval of apparent stability as something to be examined directly rather than left as interpretive background. The framework distinguishes gradual-
saturation and threshold-collapse buffer failures, introduces graded case membership (canonical, compound, candidate, application), and includes a negative-control discriminator using the K–Pg event. The Great Oxidation Event is treated as canonical, the end-Permian as a compound case, the Ediacaran–Cambrian transition as a hypothesis program, and the Anthropocene as an ongoing application. The Anthropocene section develops the idea of an effective intervention window whose closure depends on slack depletion, failure mode, and subsystem irreversibility. In the Anthropocene application, the framework shifts diagnosis from tracking state change alone to assessing the remaining slack of buffering structures whose apparent persistence may mask declining intervention capacity. The paper closes by raising the Anthropocene problem of whether reflexive producers can adapt early enough to the altered medium they’re creating.
