/**
 * Theme B smoke — errorClass classification end-to-end.
 *
 * Validates the contract layers without hitting the DB:
 *  - classifyError covers each branch
 *  - Strategy types expose errorClass on StrategyCheckResult
 *  - Rules engine accepts errorClass + errorClassIn predicates
 *
 * Run: npx tsx scripts/smoke/b-errorclass.ts
