 # migrate-seasons.sh — move old-format seasons clips into the new sky-cam
 # directory structure for astronomical year 2025 only (Winter 2025-26 onward).
 #
+# Every *-final.mp4 clip is placed in the correct movement directory based on
+# its YYYY-MM-DD filename date, regardless of how the old script labelled it.
+# montage-mvt.sh re-adjusts speed for the whole movement anyway, so per-clip
+# speed accuracy doesn't matter.
+#
 # Earlier years (Autumn 2025 / ASTRO_YEAR=2024 and before) are skipped.
 #
-# Two categories of old file:
-#   MIGRATE    — clips from the legacy script (filename has "Dayof<N>" with no
-#                preceding digit, e.g. 2026-03-21_Mvt3-Dayof92-final.mp4)
-#                → moved to the correct $MOVIES_DIR/<cam>/2025/<Season>/Mvt<N>/
-#
-#   QUARANTINE — clips produced by the later broken script that recorded a
-#                specific day number but used the wrong movement total
-#                (filename has Day<digit>of92, e.g. 2026-04-10_Mvt1-Day21of92-final.mp4)
-#                → moved to $MOVIES_DIR/<cam>/2025/quarantine-old-scripts/
-#                   Review and delete when you're done:  rm -rf <quarantine dir>
