## Latihan 1 — Completeness Check

| Skenario | Data Point Diharapkan | Data Point Tersedia | Hilang | Penanganan |
|----------|----------------------|--------------------|---------|-----------| 
| S1 | | | | |
| S2 | | | | |
| S3 | | | | |

**Simulasi: 2 run hilang (timeout). Dampak:**
> ___________________________________________________

**Keputusan penanganan data hilang:**
- [ ] Re-run
- [ ] Hapus skenario
- [ ] Lanjutkan dengan catatan

## Latihan 2 — Anomaly Investigation

**Skenario anomali:** Satu skenario menunjukkan performa 10x lebih baik dari rata-rata.

| Langkah Investigasi | Temuan |
|--------------------|--------|
| 1. Cek apakah bug di kode | |
| 2. Cek cache effect | |
| 3. Cek parameter input | |
| 4. Cek environment (background process) | |
| 5. Re-run dengan seed berbeda | |

**Keputusan:** [ ] Bug / [ ] Cache effect / [ ] Genuine result
**Justifikasi:** ________________________________________
