Shared-reference native controls

24/24 generated identities pass; state: complete.

The tangent controls retain every normalized column; independent stationary-pose inputs and broad-region probes complement comparison with the unchanged native engine. All native outputs/Jacobians and bound calls are preserved.

This finite qualification does not establish long-record usefulness, whole-program floating-point enclosure or observational coverage. No original files, Earth-model fits or protected ESA outcomes are read.

Frozen scope and allowance · Regrouping method · Roadmap.

All 27 physical directions and six bounded shared-error columns remain. Probe checks use their actual known-control common vectors; they are never independently chosen per epoch.
