Bounded walk over the indexed stablecoin settlement flow graph from a wallet: payer<->recipient hops, value-weighted score, entity-aware node keys, attributed-node stop option, and sanctioned-node markers. This is an explainability primitive, not a detector verdict, identity/control assertion, AML decision, or legal advice. Subjects over the degree gate (~50k edge-rows) return hop 1 only with frontier_truncated=true. window_from present means the answer was built from that date, the edge-grain horizon, not from the start of the requested window; the default window all, 90d and 1y included (/v1/methodology edge_grain_horizon). When window_from is present, read the graph as covering that span only — do not treat the absence of a counterparty, a path or a sanctioned node as evidence about anything before that date. volume on nodes is the token's raw minor units (divide by 10^decimals); volume_usd6 is the same amount in USD with 6 decimals at peg 1. On Solana (chain -1) the answer carries coverage_status for the subject address only, never for its counterparties: pending — its history is still being filled, so an empty or small answer is not final; partial — filled to a documented bound. The walk shows a finished fill after the next Solana rollup pass (about 10 minutes), and never shows history older than window_from. This read never starts a fill, so pending can also mean none was asked for yet: one compliance read of the address asks for it. A Solana answer without coverage_status could not read it in time — treat it as pending. On Solana (chain -1) the edge grain of 2026-07-20..2026-09-14 is incomplete: those days hold part of their transfers or none, because their raw rows were offloaded before a fix reached production on 2026-09-17; they are not restored, and answers do not mark them (decision of 2026-09-17). Solana's grain is never trimmed, so there the horizon that window_from reports is not where retained data ends: once window_from is later than 2026-09-14 the answer holds none of those days. An answer that reaches them — window_from on or before 2026-09-14, or no window_from over a window that includes them — counts them as floors: at least this much, never the whole, and a counterparty, path or sanctioned node missing from those days is not evidence that there was none.
