Module scenario 

Scenario-driven synthetic GNSS observable generation.

The module is sans I/O: callers pass a typed scenario and, when needed, an already loaded ephemeris source. The output is a set of contiguous arrays plus a ground-truth term ledger. RINEX OBS text is an explicit serialization step through the existing in-core RINEX observation writer.
