- sky-cam.conf: CAMERAS now includes east, north, south with staggered SCHEDULE_SEASONS times (01:00, 01:30, 02:00); fullday schedules and tuning removed - install.sh: fullday service/timer generation removed entirely - fullday-video.sh + systemd units: deleted - montage-mvt.sh: post-build technical checks (duration drift, video/audio stream presence) added; notification now includes check results and the exact verify-mvt.sh command to run - verify-mvt.sh: new interactive CLI for montage review — shows checks, plays video, deletes source JPEG folders on approval, or re-runs montage https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ

# montage-mvt.sh — compile one Vivaldi movement's daily clips into a montage.
|
|
#
|
|
# Duration matches the movement's music exactly. Attribution is overlaid as a
|
|
# translucent bar across the top of the video for the first ATTR_DUR seconds
|
|
# (fade in/out) — no separate card appended, so year-end joining is a plain
|
|
# concat with no duplicate attribution concerns.
|
|
#
|
|
# Called automatically by 4-seasons.sh on the last day of each movement.
|
|
# Can also be run manually for a mid-season preview.
|

|
|
# On the last day of Autumn Mvt 3, automatically triggers year-end-join.sh.
