/**
2+
* Baseline Comparison Benchmark — Paper Section 6
3+
*
4+
* Compares three approaches on all 31 failure scenarios:
5+
* 1. Naive Retry: sleep(5s) + retry, no diagnosis
6+
* 2. Error-Specific Retry: hand-coded if/else per category
7+
* 3. PCEC: full Perceive → Construct → Evaluate → Commit pipeline
8+
*
9+
* Output: table + JSON for paper Section 6
