Sanctioned Recent

Chain-wide recent transactions flagged as touching an OFAC-designated or mixer address, split into TWO lanes. The mixer lane is a hours-window feed (dense, ~1000/day). The sanctioned lane is the limit most-recent designated-address hits REGARDLESS of age (and >= min_usd, default $1000, to cut the address-poisoning dust that otherwise dominates the lane) — they are rare, so a fixed window is empty most of the time; each row carries its own timestamp so age is visible. Plus 24h lane counts for the tiles. SANCTIONS LANE ONLY — behavioural signals (wash-trading) never appear here.

The three queries are INDEPENDENTLY guarded and each carries a hard timeout: a slow/failed lane degrades to empty on its own, available is true if ANY lane succeeded, and lanes reports per-lane health — one slow lane never takes the whole feed down (the prod outage this fixes, where the unbounded sanctioned scan timed out and the single try/except failed everything). Requires auth (not in PUBLIC_PREFIXES); never 500s the desk.
