One untradable ticker rejected everything alongside it. In a single day that was
93 proposals discarding 171 predictions, and 76 of those named something we could
trade perfectly well. They were lost because a sibling in the same response said
EURUSD.
Tradability is a filter, so it applies per prediction now. The untradable one is
dropped and logged, its siblings are kept, and the stored payload records what
was removed so the filtering is auditable rather than invisible.
Lookahead deliberately still rejects the entire proposal. Evidence that did not
exist at the proposal's own cutoff means the response is corrupt rather than
merely untradable, and keeping the rest of it would hide the one thing most worth
seeing. Both halves are pinned by tests.
