Legacy DSR restatement

By , Canli Capital

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

Current selection context: N=228, identity-aligned V[SR]=0.0008957471.

  • 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.
