00 Production

Success (Reported VSCU JAR Variant)

Two-digit success variant reported for the VSCU JAR. Unconfirmed by direct observation: live signings against the real VSDC 2.0.6 sandbox JAR (2026-07-06) returned "000" per the spec §3.3.6 sample. Keep "00" in your success set defensively.

Likely Causes

Reported for some VSCU/VSDC builds (unconfirmed — live VSDC 2.0.6 returns "000")

Fix

Normalize all success checks to check membership in {"0", "00", "000", "0000"} rather than equality to "000".

Gotcha

Any hardcoded if resultCd == "000" check will silently swallow this as a failure, causing every VSCU invoice signature to appear unsuccessful with no exception raised.
