Reproducibility Core for "Beyond the Euclidean Highway: A Conditional Placement Law for Hyperbolic Supervision in Expert Language Models" — v2.0 restricted historical record

Open manuscript-matched package: The public reproducibility package matching the version DOI printed in the manuscript is 10.5281/zenodo.21609491 (v1.8). That record contains the disclosure-minimised public files and a statistics-only reanalysis. This v2.0 record is retained under restricted access as a historical provenance object in the concept-DOI version chain. Its files are not the public source package because a disclosure-safety review found operational implementation and telemetry beyond the manuscript verification need. Access requests are not being granted for this historical payload. The public v1.8 correction preserves the manuscript display values, the exact DOI cited by the paper, and the original bytes in an author-controlled restricted evidentiary archive while excluding model-building and training implementation, operational topology, stability and recovery implementation, raw states and logs, internal paths, trained artifacts, private corpora and proprietary ontologies.
