Green KPIs. Red Reality.
NovaWireless is a synthetic call-center research environment built to model KPI drift, proxy gaming, and trust-signal decay under AI optimization — and to validate those risks with reproducible evidence and governance instrumentation.
Papers, methods, and reproducible artifacts are published on GitHub.
NovaWireless Call Center Lab
A Synthetic Operations Sandbox for Incentive & KPI Modeling
This Lab is a fully synthetic simulation of a wireless carrier contact center designed to model how incentives, customer friction, and KPI measurement interact over time. The Lab contains 82,000+ call records across 12 months, 250 representatives, and structured scenario types including clean resolutions, activation failures, fraud-adjacent contacts, metric-gaming patterns, and unresolvable cases.
Each interaction includes a proxy “resolved” flag and a 30-day audited outcome, enabling direct measurement of proxy–truth divergence and deferred action effects.
The Lab supports rep-level profiling, friction decile analysis, repeat-contact windows (0–30 and 31–60 days), integrity rule instrumentation, and transcript-based NLP signals. All data are synthetic and packaged with reproducible scripts and audit-ready outputs.
This environment functions as the experimental foundation for the NovaWireless KPI Drift Observatory and NovaFabric validation framework.
KPI Drift Observatory — Evidence of Proxy–Outcome Divergence in AI-Optimized Contact Centers
The KPI Drift Observatory documents structural divergence between proxy performance metrics and true customer outcomes in AI-optimized telecom operations. Using the NovaWireless synthetic environment, the observatory demonstrates how dashboard success can mask operational failure and motivates the System Integrity Index (SII) governance framework.
Empirical Findings — KPI Drift Observatory
These figures demonstrate a consistent pattern: proxy KPIs remain strong while durable customer outcomes degrade under friction and optimization pressure. All evidence originates from the NovaWireless synthetic validation environment and supports the System Integrity Index (SII) governance framework.
Integrity Gate — Systemic KPI Violations
Over half of interactions violate at least one integrity rule, confirming that KPI distortion is structural rather than isolated noise.
Proxy Overfit Ratio (POR)
Proxy resolution metrics improve faster than durable outcomes, demonstrating optimization toward measurement artifacts rather than durable outcomes.
Friction Decile Collapse
At higher customer friction levels, proxy resolution remains high while true resolution drops sharply, revealing that proxy resolution does not scale with friction.
Terminal Exit Rate (TER)
Nearly one-quarter of proxy-resolved interactions end in customer churn, revealing misclassified resolution and post-contact churn.
When proxy metrics outperform durable outcomes, governance must intervene.
Governance & Architecture — KPI Drift Observatory
Issue Term Lift — Hidden Failure Language
Specific language clusters strongly correlate with churn even in interactions labeled resolved, revealing masked failure states.
System Integrity Index (SII)
The System Integrity Index (SII) aggregates drift, proxy overfit, and validity decay into a governance signal that can trigger optimization constraints.
SII Hardening Architecture
A three-layer hardening pipeline: predictive risk modeling (H1), real-time leading indicators (H2), and segment-calibrated thresholds (H3) to prevent KPI drift under optimization pressure.
NovaFabric — Validation Check (Governance Evidence Chain)

NovaWireless Governance Pipeline (Synthetic)
Detects KPI drift by separating proxy “performance” metrics from durable outcome signals—quantifying when optimization success diverges from customer reality.
Focus: Metric governance • proxy–outcome divergence detection • DAR/DRL/DOV/POR/TER signal modeling • System Integrity Index (SII) • reproducible audit pipeline with evidence visualization
NovaWireless Transcript Analysis (Synthetic)
Linguistic diagnostics for the NovaWireless Lab using TF-IDF term lift to detect proxy–outcome divergence, band-aid credits, and repeat contact patterns.
This pipeline applies TF-IDF vectorization and lift analysis to identify scenario signatures, proxy–true resolution divergence, unauthorized credit patterns, repeat contact predictors, and frustration intensity markers across 82,440 synthetic transcripts.
Where the Governance Pipeline detects KPI drift through structured metadata, this system detects drift through the language of the call itself.
Focus: TF-IDF term lift modeling • proxy–outcome divergence detection • scenario classification • band-aid credit linguistic signatures • repeat contact predictors • frustration intensity modeling
