Sigilith: A Minimal Structural Methods Demonstration

Sigilith is a domain‑agnostic structural analysis framework for characterizing symbolic systems through stability, drift, contradiction, and collapse dynamics. This deposit presents the minimal reproducible implementation of Sigilith Core v1.0 and the canonical Benchmark 1 v0.4 run. The methods compute four structural metrics, classify local primitives, segment higher‑order regimes, and detect collapse using a data‑driven threshold. Benchmark 1 demonstrates the full structural progression from stability to drift, instability, a transient local basin, and terminal collapse, providing a transparent reference terrain for replication and validation. This release establishes the baseline implementation for future extensions of the Sigilith framework.
