Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
Quarter-over-quarter change of an institutional manager's Form 13F portfolio. Give a CIK or name and get every position bucketed as new, added, reduced, sold out or unchanged, with per-position share and dollar deltas and a net flow summary, from two consecutive 13F filings, cited to both.
