+# Fix: supplement_schedule() — scheduled_at NULL fallback
+
+**Дата:** 2026-04-25  
+**Файл:** `fr24_worker.py` → функция `supplement_schedule()`
+
+## Проблема
+
+В SQL INSERT `supplement_schedule()` поле `scheduled_at` вычислялось простым CASE-выражением:
+
+```sql
+CASE
+    WHEN fa.origin_icao IN ('UUEE','UUDD','UUWW','UUBW')
+    THEN fa.datetime_takeoff
+    ELSE fa.datetime_landed
+END AS scheduled_at
+```
+
+Если `datetime_takeoff` и `datetime_landed` оба NULL — поле получало NULL, что ломало логику расчёта задержек.
+
+## Исправление
+
+Обёрнуто в `COALESCE` с fallback на `fa.first_seen`:
+
+```sql
+-- scheduled_at: takeoff time for departures, landed for arrivals; fallback to first_seen
+COALESCE(
+    CASE
+        WHEN fa.origin_icao IN ('UUEE','UUDD','UUWW','UUBW')
+        THEN fa.datetime_takeoff
+        ELSE fa.datetime_landed
+    END,
+    fa.first_seen
+) AS scheduled_at
+```
+
+## Деплой

+| Шаг | Статус |
+|-----|--------|
+| Локальный файл отредактирован | ✅ |
+| VM `/home/fr24/projects/fr24/ingest/tracks_fr24/fr24_worker.py` обновлён | ✅ |
+| `docker cp` → `fr24-tracks-fr24:/app/fr24_worker.py` | ✅ |
+| Верификация в контейнере | ✅ |
+
+> **Примечание:** Фактический путь исходников на VM оказался  
+> `/home/fr24/projects/fr24/ingest/tracks_fr24/fr24_worker.py`  
+> (не `tracks_fr24/` в корне projects, как было в задаче, а `ingest/tracks_fr24/`).
