Metric Saturation
Known Issue (v30 Discovery)
ฯ=0.0000 walk-forward stability metric was saturated. Corrected to ฯ=0.1184 using non-saturated CRITICAL-day rate metric.
Current Status
- Embeddings: 402 existing embeddings clean (no duplicates, no NULLs)
- Gematria distribution: mean 46.3, range 7-169, 88 unique values (healthy diversity)
- Digital root distribution: uniform across 1-9 (no saturation)
- Isolated entities: 15 (negligible)
KG Quality
| Metric | Value | Status |
|---|---|---|
| Isolated entities (no edges) | 15 | โ |
| Entities without domain | 16 (after v31.2) | โ |
| Domain coverage | 99.8% | โ |
Recommendations
- โ Fix edge-of-window overprediction (documented, for v31.2)
- โ Document measurement methodology (completed)
- โ Add saturation detection to daily pipeline (recommended for v32)
- Investigate 2 empty databases (domain_observations.db, gematria.db) โ can be removed or repurposed
