+# === NOTES ===
+#
+# New primitives needed:
+#   SOURCE_LIST - collect multiple inputs into a list
+#   ANALYZE(feature: beats) - detect beats, output { beat_times, tempo }
+#   GROUP - chunk data into groups, output segments
+#   MAP - apply operation to each item in a list
+#   RANDOM_SLICE - extract random segment from random pool item
+#
+# Data flow:
+#   music → ANALYZE → beat_times[] → GROUP → segments[] → MAP → video_slices[] → SEQUENCE
+#
+# The key insight: ANALYZE outputs DATA that flows to GROUP/MAP,
+# while media files flow through SEQUENCE/MUX
