/**
 * Baseline Comparison Benchmark — Paper Section 6
 *
 * Compares three approaches on all 31 failure scenarios:
 *   1. Naive Retry: sleep(5s) + retry, no diagnosis
 *   2. Error-Specific Retry: hand-coded if/else per category
 *   3. PCEC: full Perceive → Construct → Evaluate → Commit pipeline
 *
 * Output: table + JSON for paper Section 6
