Base social intelligence: a Base sentiment read + quality-screened Base tokens (CoinGecko-listed, market-cap/age/liquidity gated) catching attention, each labelled with the basis it stands on (`rankedBy`: measured trusted-KOL signal, or the on-chain screen plus engagement), with KOL quotes inside a published window (`evidenceWindowDays`). Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.
