# Incident Report: LIFE-INC-0001

## Summary

| Field | Value |
|-------|-------|
| **Incident ID** | LIFE-INC-0001 |
| **Title** | Scheduler terminated after first execution |
| **Severity** | High |
| **Status** | Resolved |
| **Detected** | 2026-07-05 02:49 UTC — Burn-in monitoring |
| **Resolved** | 2026-07-05 02:50 UTC |

## Impact

- **Reality Latency:** Increased from target (<60 min) to 661 minutes (~11 hours)
- **Data Freshness:** Stale — no new observations created
- **Coverage:** 181 roads affected
- **User Impact:** None (system not yet customer-facing)

## Root Cause

The scheduler executed one iteration of the weather pipeline and then exited. The original implementation lacked a persistent execution loop. It performed a single run and terminated successfully, giving the appearance of correct behavior during manual testing.

**Code defect:**
```python
# BEFORE (defective)
if __name__ == "__main__":
    run_weather_job()  # Runs once, then exits
```

## Corrective Action

Implemented persistent execution loop with exception handling:

```python
# AFTER (corrected)
if __name__ == "__main__":
    run_weather_job()  # Run immediately
    while True:
        time.sleep(3600)  # Wait 1 hour
        try:
            run_weather_job()
        except Exception as e:
            logger.error(f"Scheduler error: {e}")
            time.sleep(300)  # Retry after 5 minutes
```

## Preventive Actions

1. **Golden Dataset updated** — Added Runtime Longevity Test
2. **Burn-in requirements updated** — Continuous execution verification required
3. **Monitoring enhanced** — Alert if no observations created within 2 hours

## Lessons Learned

> "A system is not production-ready because it runs once. It is production-ready because it continues to run correctly over time."

- Manual testing of a single execution is insufficient for scheduled jobs
- Burn-in periods must verify sustained operation, not just correctness
- Monitoring must detect absence of expected activity, not just errors

## Verification

- [x] Scheduler restarted with corrected code
- [x] New observations created within 1 minute
- [x] Reality Latency restored to <1 minute
- [x] Burn-in clock reset to require 72 hours of continuous operation
