# Legacy DSR restatement

This is a correction ledger, not a performance upgrade. Original artifacts remain intact.

Current selection context: **N=162**, identity-aligned **V[SR]=0.0009605969**.

- Restated: 33 variants across 5 families.
- Retired for missing return series: 7 families.
- Current DSR ≥ 0.95: 0 variants.

## Retired historical DSR claims

- **exp2_crypto_vrp** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.
- **alphamax_hyst_live** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.
- **alphamax_turnover** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.
- **alphamax_volscale** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.
- **alphamax_weighting** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.
- **alphatrend_arp** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.
- **alphatrend_breadth** — The persisted artifact contains summary statistics but no variant-level return series. DSR depends on observations, skew and kurtosis; it cannot be honestly reconstructed from annualized Sharpe.

## Executable-code status

All 12 historical probe paths now use identity-aligned union accounting or fail closed at preflight. There are 0 executable raw-row DSR paths. Separately, 7 summary-only artifact families remain retired and cannot be treated as approved evidence.

## Interpretation boundary

This restates DSR only. It does not upgrade data quality, validation grade, sleeve admissibility or investment performance, and it does not alter original artifacts.
