# Test fixtures

## `scarlet_fire_otis_mcdonald.mp3`

"Scarlet Fire" by **Otis McDonald** — a royalty-free / license-free track
(YouTube Audio Library; distributed via Pro-Sound.org). Used as a real-world
audio fixture for the enrichment pipeline.

What makes it a good fixture: its **embedded ID3 tags are junk**
(`title=Sound_13958`, `artist=Music Track`, `album=Музыка`, `genre=Hip Hop & Rap`)
while AcoustID identifies it with very high confidence as *Scarlet Fire /
Otis McDonald*. So it exercises both:

- the offline tag reader (deterministic, always runs), and
- the "trust a high-confidence AcoustID match over junk tags" path
  (`acoustid_trust_score`), which only runs when `fpcalc` + an AcoustID API key
  + network are available — see `tests/test_real_file_enrichment.py`.

Because it's license-free, it may also seed a built-in demo track for fresh
instances.
