Four-minute recording format compatibility
6/6 API cases passed; elapsed 5.85 seconds.
Charged 24/24 native queries, zero interval bounds. Each case retains all 48,000 original generated packets and compares two fixed parameter points through the legacy and current callers, including every Jacobian column and warning bit.
The same kernel implements both callers. This is a format/API check, not independent physical validation, useful four-minute bounds or observational coverage. The original fixed-clock limitation is retained; no short-history training certificate was transferred.
