Implements the primary search path for lance-graph using progressive 8-byte edge encodings and 3-hop neighborhood vector traversal. ZeckF64 encoding: byte 0 = 7 SPO band classifications (boolean lattice, 19 legal patterns, ~85% error detection), bytes 1-7 = distance quantiles. ScopeBuilder: O(N²) pairwise construction of [ZeckF64; N] vectors. SearchCascade: HEEL (1 vec) → HIP (50 vecs) → TWIG (50 vecs) → LEAF. 32 tests (22 unit + 10 integration), all passing. https://claude.ai/code/session_01NUMNX67KZrFiTQK7erFQuH
