nx_genealogist.nx -- the GENEALOGIST: prevent capability DUPLICATION (operator: don't rebuild what we already have). Before the Builder authors a capability, the Genealogist checks the registry for an equivalent. A capability has a two-axis SIGNATURE: (artifact_kind, objective_kind). It is a DUPLICATE only if BOTH match -- so "allocation optimizing IMPORTANCE" (imatrix) and "allocation optimizing PERCEPTION" are DIFFERENT capabilities (same artifact, new objective = novel), but proposing imatrix twice, or re-proposing PSNR fidelity, is caught and refused. This keeps the 100+ caps from bloating into near-duplicates and forces REUSE of what exists. RACI: the Genealogist guards lineage (it does not build or verify). license_tier: ORIGINAL Refs: code-hygiene organ.
