## Notes

### Diagram Legend

**Colors:**
- 🟢 Green: Success paths, completed states
- 🔴 Red: Error paths, failed states
- 🟡 Yellow: Decision points, important checks
- 🔵 Blue: Processing steps, data transformation
- 🟣 Purple: External services, special features

### Key Decision Points

**All-Done Check:**
- Critical for preventing premature status updates
- Only proceeds when ALL assets successful
- Failed assets cause retry on next run

**Single-Run Mode:**
- Each script processes ONE item (campaign or file)
- Cron handles scheduling (every 5 minutes)
- Allows controlled processing
- Easy to test and debug

**Box Metadata:**
- Optional enhancement
- If template not found, continues without
- Doesn't block upload if missing

### File Naming

**A1→A2 and B1→B2 (Box Upload):**
- Original: filename.ext
- With Tracking: filename_ABC123.ext

**A2→A3 (DAM Upload):**
- From Box: 1234567_RAF_DE_de_TEST_OLV_001_6S_16x9_ABC123.mp4
- To DAM: RAF_DE_de_TEST_OLV_001_6S_16x9.mp4
