 - Review every tolerance against actual observed errors from `-s` output.
-- If a constant's margin is too loose (e.g., `1e-6` when error is `1e-10`), tighten to `1e-8`.
 - **If a test fails due to a tolerance being too tight, report the observed error to the user and ask whether to loosen the constant or investigate the root cause. Never silently widen a tolerance.**
 - Refer to the tolerance reference table in Section 3 for constant names.

+- BurnResult capture (position, velocity, true anomaly at exact burn time)
 - Body propagation (elliptical + parabolic via Barker's equation)
 - Orbital↔Cartesian transforms (full z-x-z Euler rotation)
 - Velocity drift detection and element reconstruction
