Venue observations were taken on August 3, 2026 unless otherwise dated; displayed quotes on thinly traded ladders are point-in-time and move. The pricing violations documented here sit on events with negligible volume and are read as documentation artefacts of markets nobody is making, not as executable opportunities — no arbitrage is asserted and none is recommended. Nothing here is a solicitation to trade on any venue, and access restrictions described are stated as fact, not as guidance to circumvent them. Research and education, not investment advice.
