A body-unsigned v1.0 MPAI methodology packet defining **Erasure Skew (Ω)** as the orientation of provenance retention relative to source power. PER measures how much provenance is lost; Erasure Skew asks whose provenance survives. Conceptually, the packet describes Ω as covariance between retention and Retrieval Capital. Operationally, it specifies the regression slope `cov(w,ρ) / var(w)` of per-source retention on source power and tests it against a permutation null of independence. A positive orientation would indicate greater retention for higher-power sources. The metric does not establish intent, design, or culpability. Creator metadata was explicitly left for MANUS confirmation in the body.
