Simple gates pass positive-risk, severity-weighted BLOCK scores to their
configured aggregator. Cascades use only the current stage’s positive-risk,
severity-weighted BLOCK findings and that stage’s aggregator. With positive
blocking findings, simple gates block when the aggregate is greater than or
equal to threshold; cascade stages block only when their own score is strictly
greater than threshold. Operational faults can block independently.
Scores must be in the 0.0–1.0 range. MaxWithBonusScoreAggregator caps its
result at 1.0 but does not clamp below zero; a negative bonus can produce an
invalid negative result. Findings with other actions remain in the result but
are not passed to an aggregator.
Configure one aggregator at the simple root or within each cascade stage:
score_aggregator:
score_aggregator: cerbia.core.score_aggregators.MaxScoreAggregator| Aggregator | Best for | Behavior |
|---|---|---|
A single severe signal should dominate. |
Returns the highest score. |
|
Independent signals should raise confidence. |
Adds a configurable bonus for every score after the first. |
|
Average evidence should drive the verdict. |
Returns the arithmetic mean. |
All three return 0.0 for an empty input list.
