Java

Recompute a claimed backtest report with the deterministic Wickra engine and confirm or refute it, on the JVM over the Wickra C ABI via the Foreign Function & Memory API (FFM/Panama, JDK 22+). A doctored claimed_report cannot pass, because verification recomputes rather than trusting the supplied numbers.

Everything goes through a Verifier driven by JSON commands — the same command protocol every Wickra binding shares.

java

import org.wickra.verify.Verifier;

try (Verifier verifier = new Verifier()) {
    String claim = "{"
        + "\"strategy\":" + strategySpec + ","          // a wickra-backtest StrategySpec
        + "\"dataset_ref\":{\"kind\":\"inline\",\"data\":" + data + "},"
        + "\"claimed_report\":" + report                // the report being checked (untrusted)
        + "}";
    String verdict = verifier.command("{\"cmd\":\"verify\",\"claim\":" + claim + "}");
    System.out.println(verdict); // the full Verdict as JSON
}
