Direct LVK Event Confrontation and Locked Survival Protocol for the Kerr FCLET Shell Sector

We define the direct event-level confrontation architecture of the admissible Kerr shell sector of the finite-capacity latency–erasure theory against real compact-binary merger data. The previous stages of the program already established the full confrontation infrastructure. Article 83 constructed the rotating-shell theory and fixed the numerical zero-spin anchor of the shell spectrum. Article 84 built the detector-facing waveform family, the benchmark atlas, the analytic false-Kerr mimicry map, and the identifiability corridor with decisive-island regions in which the theory becomes genuinely distinguishable from standard Kerr-family inference. The present paper executes the next indispensable step: it locks the real-event confrontation protocol itself. The confrontation is carried out under a blind protocol with locked shell-law hyperparameters and a locked event-authority hierarchy. Event-specific remnant masses and spins are permitted to move the realized theory point across the admissible confrontation domain, but the shell architecture itself is not re-tuned from event to event. This permanently closes the standard ad hoc rescue route by which alternative strong-field models are often kept alive after seeing the data. The primary confrontation set is explicitly anchored by GW150914 and GW190521, while all additional events enter only through a declared authority hierarchy and under the same pre-locked benchmark shell structure inherited from Articles 83 and 84. The paper is organized around four event-level diagnostics. First, we compute the Bayesian evidence gain of the Kerr FCLET shell model against Kerr, overtone-enriched Kerr, and, when required by event morphology, extended Kerr-family null models. Second, we determine whether any apparent FCLET support localizes inside a decisive-island region or merely inside a Kerr-mimickable zone. Third, we quantify posterior compression toward the null-shell face, thereby distinguishing simple Kerr compatibility from active detector-level shell erasure. Fourth, we impose an operational network-coherence rule on delayed shell structure, preventing single-detector artifacts from masquerading as physical shell support. The confrontation also includes a structured ablation program. A real FCLET-favorable event is not defined only by positive evidence against Kerr-family competitors. It is defined by component necessity: the FCLET preference must weaken in a controlled and interpretable way when one of the shell architecture’s core physical channels is removed. Accordingly, the full shell model is compared not only against external Kerr-family nulls, but also against controlled internal ablations: no-delay, no-excitation-hierarchy, no-boundary-response, and no-coherence variants. This converts the event analysis from generic model comparison into a physics-of-evidence test. The event-level outputs are exact epistemic states rather than descriptive labels. Each event is classified into one of the confrontation classes – , depending on whether it supports decisive-island survival, survives only in ambiguity, compresses the shell branch toward the null face, imposes decisive exclusion pressure, or remains information-poor. The event family is then synthesized hierarchically through a shared shell-law posterior and globally through the detector-facing survival geometry, producing one of the final verdicts – : nontrivial detector-facing survival, ambiguity-only survival, null-shell retreat, or direct detector-facing elimination. The global outputs of the paper, are therefore defined as protocol-level confrontation summaries to be computed once the locked event set has passed through the declared likelihood, coherence, and ablation filters. The present paper does not claim completed empirical verdicts in advance. It establishes the exact architecture under which later real-event adjudication acquires scientific force. In this sense, the paper is not a soft ringdown note and not an unconstrained event scan. It is the locked empirical tribunal of the detector-facing Kerr FCLET shell sector.
