Native timing-derivative checks

Finished 2 scheduled endpoints: 2 successful / 0 errors; 24 native calls, with zero optimizer starts. The completed control is reused unchanged from the preceding diagnostic; no control is rerun. These fixed-endpoint diagnostics preserve every scientific disposition and stopping limit.

Preserved control and earlier preflight errors.

The smallest steps can encounter floating-point subtraction limits. Large-step differences may reflect real changes between adjacent measured increments; neither is automatically a derivative defect. The saved measurements include per-axis errors, signed objective changes, packet distances and full/half coupled corrections. No result is relabeled.
