# Dataset preparation v1.0.0

Source scientific version: CHISÆL–NEXYTHRA II 1.0.0, 9 October 2026.

Added a Hugging Face Dataset card, 19 explicit CSV/JSONL configurations, schema descriptions, dataset citation, SHA-256 provenance, upload instructions and scripts. Preserved all 82 source files unchanged. Added no scientific theorem, proof, numerical simulation, peer-review result, historical priority certification, or redistribution license.

The deterministic source suite was rerun in an isolated working copy: 1,139 passed, 0 failed, matching the source. No numerical simulation or figure regeneration was performed. Dataset configuration loading and byte preservation were tested locally; no live Hub repository or server viewer was tested.
