## 2. Core Technological Architecture

### 2.1 Expected Revenue Per Impression (ERPI) & Revenue Per Search (RPS)
Crosane balances customer query intent with commercial fundamentals:
- **Net Margin Contribution**: Prioritizes high-margin products and house brand heroes over zero-margin clearance lines.
- **Stock-Depth & Size-Curve Awareness**: Automatically deprioritizes out-of-stock items, broken size runs (e.g. only XS left), and high-bounce clearance traps from top ranking slots.
- **28-Day Rolling Demand Velocity**: Identifies rising seasonal patterns, repeat query trends, and viral items dynamically without relying on stale quarterly metrics.
- **Order Webhook Truth**: Syncs directly with post-checkout order webhooks to deduct returns and cancellations before validating ranking lift.

### 2.2 Dual-Chamber Scientific A/B Validation Engine
- **Deterministic 50/50 Traffic Split**: Splits live visitor sessions between Arm A (Incumbent Search Baseline) and Arm B (Crosane Revenue Optimized).
- **Sample Ratio Mismatch (SRM) Protection**: Continuous statistical monitoring ensures honest experimental balance without algorithmic drift.
- **Zero-Risk Rollbacks**: Merchants can revert traffic instantaneously to incumbent search infrastructure with zero downtime and zero contractual penalty.

### 2.3 Sovereign Merchant Governance
- **Merchant Rule Supremacy**: Strategic merchant rules (pinned seasonal flagships, brand exclusivity, margin floors) evaluate first and are 100% deterministic.
- **No Black-Box Overrides**: Automated bandits and ranking models are strictly constrained within merchant-defined business boundaries.

### 2.4 High-Performance Edge Layer
- Sub-5 millisecond edge re-ranking latency.
- Compatible with existing headless and storefront architectures with zero theme modifications.

| **Stock Protection** | None; surfaces clearance traps | Weak; pushes broken sizes | Strict full size-curve verification |
| **Merchant Control** | Brittle manual synonym rules | Opaque autopilot overrides | Sovereign rule priority + explainability |
| **Proof Standard** | Subjective assumptions | Synthetic offline simulations | Continuous live 50/50 A/B test chambers |
| **Integration** | Monolithic search migration | Multi-month suite replatforming | Fast <5ms edge layer atop existing stack |
