Concept Spectroscopy — Archival data package (dialog apparatus, per-cell results, blind-judge record), Paper1

The complete evidence base for the paper: the 60-dialog measurement apparatus and frozen inventories, found-text passage sets with provenance, per-cell result JSONs for all five architectures (detection permutation nulls, causal propagation, dose-matched specificity, steering, found-text), the leave-one-domain-out direction-stability output for all 25 cells, the full blind-judging record with content-hash manifest, and a frozen snapshot of the public reproduction codebase (github.com/c-by-b-ai/concept-spectroscopy-public, tag paper1).
