Validating a Causal Assay for Engineered Self-Indexed Temporal State

This record reports and validates a preregistered causal assay on an engineered, transparent finite reference construction. In the registered finite construction, a relationally self-indexed temporal state causally influenced future-directed choice through the separately intervened prospective-evaluation path. The reference system is deliberately minimal and deterministic. The demonstrated dependencies are consequences of the registered construction under controlled intervention and are extensionally compatible with a relational lookup. The contribution is methodological: a frozen intervention battery combining self/other attribution contrasts, interchange, ablation, restoration, downstream clamps, deterministic reruns, fail-closed analysis, and hash-bound evidence. The deposit includes the English manuscript, a Hungarian companion version, and a public reproducibility/verification package. The public package verifies the published assay and evidence chain; it is not a complete disclosure of subsequent or unpublished architecture. This work does not provide evidence of phenomenal consciousness, subjective experience, personhood, AGI, human-equivalent selfhood, spontaneous emergence of a self-model, or architectural novelty.
