TrustBadge called useTrustScore per card, which fetched the viewer's follow list plus up to 100 friends' follow lists for EVERY card. The graph does not depend on the target, so useViewerGraph computes it once per viewer (one shared React Query) and deriveLocalScore returns the same 100/90/60/0 ladder (the NIP-05 30 tier classified as unknown anyway). TrustBadge now costs no per-card network work on top of the batched assertion read. Behaviour preserved; logged-out users still use the house graph. Also records the ANALYZE=1 bundle findings in AGENTS.md.
