Public audit view. Release-level findings, evidence categories and outcomes are shown here. Internal identifiers, physical mappings, exact thresholds, calibration parameters, repair mechanics and orchestration remain controlled.

Backtest at a glance
Public event-ablation coverage and categorical outcomes.
Ablation outcomes
Event-by-event public status
A confirmed signal means the event improved explanatory fit in the controlled backtest. The public site deliberately avoids publishing exact error deltas or model-response trajectories.
| Historical event | Public validation outcome |
|---|---|
| FP2020 Commitment / Renewed Family Planning Push | Confirmed explanatory signal |
| Boko Haram Insurgency Displacement | Confirmed explanatory signal |
| Structural Adjustment Programme (Nigeria) | Confirmed explanatory signal |
| National Policy on Population for Development | Confirmed explanatory signal |
| Nigerian Oil Boom | No confirmed signal in available benchmark window |
| COVID-19 Pandemic (Nigeria) | No confirmed signal in available benchmark window |
| Nigerian Civil War (Biafra) | No confirmed signal in available benchmark window |
| Fertility Decline Stall/Rebound | Recalibration review candidate |
Method boundary
Evidence is visible; calibration mechanics are not
External benchmark families, event identity and categorical validation status are public. Exact error scores, index-year selection, scenario curves, coefficients and recalibration values are part of the controlled methodology pack.
