Inspect a five-point, two-observer synthetic route with a controlled hill obstruction, partial source coverage, a NoData area and synthetic airspace context.
Illustrative layout — frozen synthetic fixture. Not operational flight planning or surveyed truth.
01 / Expected findings
The fixture controls clear, warning, blocked and unknown states.
These states are assertions in the repository fixture package. They demonstrate the intended product contract; they do not describe a proposed real flight.
Blocked
Hill crest
The controlled 120 m crest interrupts the intended geometric sightline.
Unknown
NoData zone
The missing terrain area remains unknown and is not replaced by zero elevation.
Warning
Synthetic review zone
The route crosses a synthetic area that requires review; it is not official airspace.

02 / Limitations
Orientation context is not operational truth.
The UK origin helps make the example legible, but every finding is generated from a local synthetic scene.
Synthetic deterministic terrain and airspace are used for product demonstration, not operational flight planning.
The UK map origin is orientation context and does not describe a real proposed flight.
The evidence pack remains draft planning support and is not a permit or authority decision.
