-# migrate-seasons.sh — map old-format seasons clips to the new sky-cam directory
-# structure using season_info.py to correctly categorize each clip by date.
+# migrate-seasons.sh — move old-format seasons clips into the new sky-cam
+# directory structure for astronomical year 2025 only (Winter 2025-26 onward).
 #
-# The old system used different movement-boundary and naming conventions;
-# this script ignores the old labels and re-classifies every clip by its
-# YYYY-MM-DD filename prefix, placing it exactly where montage-mvt.sh expects.
+# 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>
 #
 # Usage:
 #   ./migrate-seasons.sh [--dry-run] [OLD_ROOT]
 #
-#   --dry-run   print what would happen without creating any links
-#   OLD_ROOT    root of old movie archive (default: ~/drives/local-2tb/movies/sunrise)
+#   --dry-run   print what would happen without moving anything
+#   OLD_ROOT    root of old movie archive
+#               (default: ~/drives/local-2tb/movies/sunrise)
 #
-# Output: symlinks in $MOVIES_DIR/<cam>/<ASTRO_YEAR>/<SEASON>/Mvt<N>/
-#
-# After running, trigger any completed movement montages manually:
-#   ./montage-mvt.sh 2026-04-19 east   # Spring Mvt1 (just completed)
-#   ./montage-mvt.sh 2026-01-18 east   # Winter Mvt1
-#   ./montage-mvt.sh 2026-02-16 east   # Winter Mvt2
-#   ./montage-mvt.sh 2026-03-19 east   # Winter Mvt3
+# After running, trigger montages for completed movements:
+#   ./montage-mvt.sh 2026-04-19 east   # Spring Mvt1 (~20/31 days)
+#   ./montage-mvt.sh 2026-01-18 east   # Winter Mvt1 (~18/29 days)
+#   ./montage-mvt.sh 2026-02-16 east   # Winter Mvt2 (~24/29 days)
