nx_mvault_embed.nx

nx_mvault_embed.nx -- embedding-vector storage for the vault (seg-store blobs). The NishiCaption/SOTA tagger produces per-item EMBEDDINGS the schema must retain so the expensive pass runs once: - face embedding (ArcFace-class) -> identity CLUSTERING -> performer: tags - image embedding (CLIP/SigLIP) -> SEMANTIC search + near-dup detection - pose (DWPose) feature vector -> pose archetypes Stored CID+model-keyed on the sovereign seg-store (additive, versioned), so re-clustering / re-search never needs re-inference. Composes nx_registry (reg_put/reg_get) -- no new store format. license_tier: ORIGINAL
