## 1. Lens Directory & Density Classifications

Each evaluation lens targets a discrete architectural dimension and operates under an assigned budget density class (governed by Constitution §6) to calibrate thoroughness against operational budget:

> [!NOTE]
> **Density Split for `L-CODE-QUALITY`:** Discrete scans (such as hardcoded literals, secret leaks, and banned APIs) are executed at `D-HIGH` exhaustive density. Broad code style, formatting philosophies, and naming patterns are evaluated at `D-LOW` Top-N density.

## 2. Lens Catalog Governance & Principles

| Design Advantage | Operational Risk & Invariant |
| :--- | :--- |
| Comprehensive coverage of ISO/IEC 25010 and real-world production engineering disciplines. | Overlap between concurrency, reliability, and performance is arbitrated and deduped by the lead integrator in Wave 4. |
| Budget density classes prevent agents from producing unproductive, speculative essays. | Wave execution plans freeze density classes to prevent evaluators from arbitrarily downgrading thoroughness. |
| Decouples superficial code appearance from production operability, observability, and recoverability. | Developer usability (`L-USABILITY`) remains mandatory for systems with CLI, API, or configuration interfaces. |
