Operational Architecture Topology (5 Pre-Modeling Gates)
Operational Gate Parameters
Reactive Stress-Testing
Gate 1: Heuristic Rule Coverage
92%
% of cases accurately addressed by simple deterministic business rules.
Gate 2: Label Feedback Arrival
48 hours
Time required to confirm ground-truth outcome (settlement, dispute, conversion).
Gate 3: Serving Latency SLA
35 ms
Strict p99 online inference budget including network + feature hydration.
Gate 4: Feature Store Freshness
2 sec
Online feature hydration staleness (1s streaming vs 24h batch ETL).
Gate 5: Circuit Breaker Precision
84.5%
Precision floor when falling back to heuristic on model timeout/failure.
Required Minimum Lift over Heuristic
15%
Minimum statistical lift needed to justify ML training & maintenance overhead.

Architecture Trade-off: Deterministic Rule vs Full ML
| Dimension | Deterministic Heuristic | Proposed ML Pipeline |
|---|---|---|
| Coverage / Target Catch | 92.0% | 97.8% (+5.8% lift) |
| Serving Latency p99 | < 1.5 ms | 28.0 ms (SLA: 35ms) |
| Failure Mode Risk | Zero cold-start; hard-coded rules | Degrades to Heuristic (84.5% prec) |
| Annual Maintenance Cost | $15k (Rule engine tuning) | $140k (Infra, drift alerts, GPU) |
