test_moon_composite.py uses the existing repo sample frames (21-07-00.jpg east frame with thin cloud cover + full_moon_closeup.jpg as NASA render stand-in) to produce test_composite_out.jpg without needing a live NASA API call or moon detection run.

"""test_moon_composite.py — smoke-test the cloud-veil composite using local files.
|
||
|
||
Uses the sample east frame (21-07-00.jpg) and the reference moon photo
|
||
(full_moon_closeup.jpg) already in the repo to produce a composite without
|
||
needing a live NASA API call or actual moon detection.
|
||
|
||
Run from the sky-cam directory:
|
||
|
||
python3 test_moon_composite.py
|
||
|
||
Output: test_composite_out.jpg in the same directory.
|
||
|
||
The east frame (2026-04-29 21:06:45) shows the moon with visible thin cloud
|
||
cover across the sky, so the cloud-veil layer should be clearly active.
