lockedToOrbit re-rates a locked moon's W and node terms and moves their
constants so that on 2025-01-01, the date the IAU's elements were fitted
near, the pole and W are the kernel's own. Nothing checked it: with the
constants left where they were, the solar ETL passed and the suite passed,
though every re-rated moon moved (Rhea's pole 0.018 degrees, Triton 0.0054,
Miranda 0.0037, Europa 0.0027, Callisto 0.0021, Deimos 0.0016, Ganymede
0.0016, measured on the bodies.json it wrote; before the drawn node rates
were corrected, Mimas's W moved 0.21 and Miranda's pole 0.12).
lockedToOrbit now compares orientationAt at PRESENT_JD before and after,
Iapetus's pole round its orbit included, and throws past 1e-6 degrees.
Measured on the shipped catalogue: at most 4.7e-10 (Deimos's W, some 2.6
million degrees round), the pole exactly.
Guarded mutants, each through the solar ETL on the real catalogue:
- node terms' constants not moved: "Deimos's pole or W on 2460676.5 is
1.60e-3 degrees from the IAU's".
- W's constant not moved: Deimos, 9.12e-2.
- the check disabled with the first: the ETL passes (control).
The unit suite does not see it: the check runs on the kernel, which only
the ETL reads. The ETL writes the same bodies.json as before. Unit suite
866 passed.
