// Strategy: define initial orbital conditions, propagate with Orekit's
10

// Keplerian propagator, then write the ephemeris as OEM KVN using
11

// Orekit's OemWriter. The OCaml test parses the Orekit-generated KVN
12

// and verifies field extraction matches the CSV index.
13

14

// This ensures the oracle does real orbital-mechanics work — the OEM
15

// files are NOT hand-crafted templates echoed through Orekit.
