/**
 * Template Generator for Principle Compiler
 *
 * Generates RuleHost sandbox code from PainPattern descriptors.
 * Produces self-contained JS modules with `const meta` and
 * `function evaluate(input, helpers)` that can be loaded at runtime.
 *
 * PRI-439 Phase 2: canonical dialect is bare `function evaluate(input, helpers)`
 * — no ESM `export` keyword (forbidden by checkForbiddenPatterns).
 * Default return is `{ decision: 'allow', matched: false, reason: '...' }`
 * (matched=false requires decision='allow').
 *
 * SECURITY: All interpolated values use JSON.stringify or safe helpers
 * to prevent code injection through principleId, coversCondition, or regex patterns.
 *
 * PRI-44: Pure domain logic, zero infrastructure dependency.
