- New Aenebris.ML.Engine module: pure decision pipeline composing
the previously-built Loader, Inference, Calibration, and IForest
modules into a single per-request scoring path.
Engine record holds (Ensemble, Calibrator, Maybe IForest,
EngineConfig); runEngine takes a feature vector and produces
DecisionDetails (Decision, raw proba, calibrated proba, optional
IForest score). The Decision is one of DecisionHuman, DecisionBot,
or DecisionChallenge.
- Implements the escalation-gate semantics per the 2026 research
correction (over the deprecated 0.8/0.2 weighted blend):
calibrated <= humanThreshold -> DecisionHuman
calibrated >= botThreshold -> DecisionBot
otherwise (ambiguous band):
if IForest configured and ifScore >= escalation threshold
-> DecisionBot (escalation)
else if challenges enabled
-> DecisionChallenge
else
-> DecisionHuman (fallthrough)
Defaults: 0.3 / 0.7 thresholds, 0.6 IForest escalation, challenges
on by default.
- 17 tests covering: defaultEngineConfig values, decision boundaries
with NoCalibrator and no IForest (low/mid/high leaf ensembles),
ambiguous-band escalation via low-vs-high anomaly IForests,
ambiguous-band with challenges disabled (fallthrough to Human or
escalation to Bot), Platt calibrator pulling decisions across
thresholds, and DecisionDetails field correctness.
- aenebris.cabal: expose Aenebris.ML.Engine in the library stanza.
- 342 total examples passing, 0 GHC warnings on the new module.
The Wai middleware wiring (extract features -> runEngine -> route by
Decision) is the next module (ML.Middleware); Engine intentionally
stays pure / independent of HTTP machinery so it can be unit-tested
without request fixtures.
