No script defaults to SUNRISE_CAM (east) for the seasons pipeline.
Every direction is treated equally — camera name is a required arg,
not an optional override.
- 4-seasons.sh: $1 required, exits with usage if missing
- montage-mvt.sh: arg order changed to <cam> [date]; $1 required
- year-end-join.sh: $2 (cam) required
- verify-mvt.sh: $4 (cam) required
- migrate-seasons.sh: example commands updated to new arg order
- README.md: montage-mvt.sh examples updated

montage-mvt.sh, year-end-join.sh: CAM_NAME fallback referenced undefined
\$CAM_NAME — crashes under set -euo pipefail on manual runs without args.
Fixed to fall back to \$SUNRISE_CAM (same fix applied earlier to other scripts).
notify.sh: Mattermost notification guard only checked MM_NOTIFY_CHANNEL_ID,
not mattermost_url or access_token. If those are unset, curl would send a
malformed request silently. Added guards for all three required values.
install.sh: seasons/fullday service units had literal \n in After=/Wants=
lines because bash does not interpret \n in heredoc variable expansions.
Changed to \$'...' syntax so actual newlines are written, making valid
systemd unit files. Also: audio capture timer now uses \$SCHEDULE_SUNRISE
instead of hardcoded 03:00, keeping it in sync if the user changes the
schedule.
sunrise-audio-capture.sh: record_start_sec could theoretically go negative
(sunrise very early + large SUNRISE_TARGET_SECS). Added floor-at-zero guard.
daily_sunrise_video.sh: added comment explaining why audio_offset is always 0.
README.md: fix CAM_RTSP_sunrise example to CAM_RTSP_east.

Each pipeline now saves intermediate files permanently before the step most
likely to fail, so a partial failure leaves a recoverable artifact:
- daily_sunrise_video.sh: speed-adjusted video (*-sped.mp4) survives if the
drawtext overlay step fails; deleted automatically on success
- montage-mvt.sh: speed-adjusted video (*-Sped.mp4) survives if the
music-mux + attribution overlay step fails; deleted on success
- 4-seasons.sh / montage-mvt.sh / year-end-join.sh: explicit ffmpeg error
handling with targeted notify.sh calls naming the failed step and the
surviving artifact path
- montage-mvt.sh / 4-seasons.sh / year-end-join.sh: clip-duration-sum vs
music-duration drift check warns when cumulative float error exceeds 2 s

sky-cam.conf:
- CAMERAS array replaces single CAM_NAME; add a name, add its schedules,
re-run install.sh — no script editing needed
- SCHEDULE_SUNRISE, SCHEDULE_SEASONS_<cam>, SCHEDULE_FULLDAY_<cam> replace
hardcoded times in install.sh
- Notification options commented out (uncomment to enable)
- Lat/lon set to mid-Atlantic (25.0, -38.0) as neutral placeholder
install.sh:
- Loops over CAMERAS to generate per-camera sky-cam-seasons-<cam> and
sky-cam-fullday-<cam> timers with schedules from conf
- Sunrise timer remains a single sky-cam-sunrise unit (SUNRISE_CAM only)
fullday-video.sh, 4-seasons.sh, montage-mvt.sh, year-end-join.sh:
- Each accepts camera name as an argument (systemd passes it via ExecStart)
and falls back to conf default when run manually without an arg
- Camera name propagates through the full call chain:
4-seasons → montage-mvt → year-end-join
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
sky-cam.conf
- Add SCRIPT_DIR (install location) and CAM_NAME (camera/folder name)
- These are the only values that change when deploying to a new machine
install.sh (new)
- Sources sky-cam.conf, generates all systemd .service and .timer units
with correct ExecStart paths, then enables and starts the timers
- Run once after editing sky-cam.conf; run again if paths change
- Supports --system flag for system-wide install
All .sh scripts + sunrise2mm.py
- No hardcoded paths remain
- script_name=$(basename ...) derivation replaced by $CAM_NAME from conf
- sunrise_video.10s.sh now sources sky-cam.conf for BASE_DIR, CAM_NAME,
and SCRIPT_DIR (replaces all /home/motion/... references)
- sunrise2mm.py builds video path from BASE_DIR + CAM_NAME in conf
systemd/ template files kept as reference but no longer need editing
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
sky-cam.conf (new)
- Single file replaces mattermost_config.txt reference, notify_config.txt,
and the hardcoded BASE_DIR/MUSIC_DIR/TIMEZONE scattered across scripts
- Bash-sourceable and Python key=value readable (same format)
All .sh scripts
- source sky-cam.conf at startup; BASE_DIR / MUSIC_DIR from config
sunrise2mm.py
- Reads sky-cam.conf relative to script location; no hardcoded path
notify.sh
- Sources sky-cam.conf; Mattermost credentials come from there directly,
no separate mattermost_config.txt lookup needed
systemd/sky-cam-notify-failure@.service (new)
- Template unit called by OnFailure= in each service
- Sends notification via notify.sh when any sky-cam job fails
- All three .service units now have OnFailure=sky-cam-notify-failure@%n.service
Removed: notify_config.txt, sky-cam.crontab (superseded)
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
season_info.py
- Add ASTRO_YEAR: year of the Winter solstice that started the current cycle
(Spring/Summer/Autumn 2026 → 2025; Winter Dec-2026 → 2026)
4-seasons.sh
- Daily clip output path now includes ASTRO_YEAR:
movies/$name/$ASTRO_YEAR/$SEASON/Mvt$N/
montage-mvt.sh (full rewrite)
- Attribution is now a drawtext overlay (top 6 s of the video, fade in/out)
instead of an appended black card — no frame-size matching needed, and
year-end join requires no special handling
- Output path mirrors the new year-based folder structure
- Sends notification via notify.sh when done
- Automatically triggers year-end-join.sh after Autumn Mvt 3
year-end-join.sh (new)
- Concatenates all 12 movement montages for a given ASTRO_YEAR
- Output: movies/$name/$ASTRO_YEAR/$name-$ASTRO_YEAR.mp4
- Sends notification when done
notify.sh + notify_config.txt (new)
- Generic best-effort notification helper: ntfy, email, Mattermost text post
- All methods disabled by default; user fills in notify_config.txt
sky-cam.crontab + systemd/ (new)
- Crontab file: sunrise at 09:00, 4-seasons at 01:00, fullday at 02:00
- systemd .service + .timer units for all three daily jobs
- montage/year-end triggered internally, not by cron
