+# Independent source excerpts
+
+These are **evaluation-only original-song inputs**, not expected solos, production vocabulary, or the four target solos. They are deliberately outside `data/` and are never loaded by ordinary generation or required tests. Source provenance is beside each XML. The original 1917/1918 editions are from Johns Hopkins' Levy collection.
+
+The manually transcribed first four chorus measures retain the vocal rhythm, including tied values. Chord symbols are our declared harmonic reductions of the piano score. These short excerpts do not establish whole-form generalization. Preceding pickups/verses and piano figuration are outside the excerpt scope. Original scans remain in ignored `build/composer_repair/405066e/evaluation_sources/` for review.
+
+St. Louis Blues was considered, but the institutional original-score download was unavailable (403). Hindustan supplies the third independent source instead; no target arrangement was used to reconstruct missing music.
+
+Run `python -m audition.transfer_review --output build/transfer_review` through the repository Python runner. This runs the normal independent generators; no tuning/selection result flows back into production.
