ROUND 5: Ruthless prioritization. Is the count-centroid multi-hop WORTH building given: (1) it only works for frontier < ~1000, (2) the translation to XOR-space is lossy, (3) the materialized fallback handles fan-out > 40 already? What is the ACTUAL regime where holographic multi-hop beats materialized traversal? Give a concrete use case with numbers. If the regime is too narrow, say so honestly and CUT it.
