Reproduction archive for Persistence Is Not Readability: Readout-Accessible Modal Information in a Frozen State-Space Classification Study

Frozen protocols, synthetic row-level data, fitted models, predictions, analysis and figure code, result locks, manuscript files, and executable verification records for Paper 4. Scientific decisions are H1 PASS, H2 PASS, H3 PASS, and H4 FAIL. The archive supports a detector-relative separation of retained state, record accessibility, and learned task utility; it does not establish quantum advantage, broad out-of-distribution validity, or a universal reservoir-memory measure.
