Methodology and known limits
MEV trades look like ordinary swaps. Detected events get a per-trade flag in mev_events; the aggregator can exclude flagged trades from VWAP, so the policy lives there and the raw observation is kept.
Detection is conservative: served trade rows carry no direction, so no detector asserts front/back-run intent and profit_usd is always null; each event's detail.note states the evidence. Sandwich kinds need the lake's tx-order index and degrade to not-detected (never guessed) when a transaction is not indexed. oracle_deviation is reserved, and call-tree attribution awaits diagnostic-event capture.
