/**
 * v0.35.0.0+ ZeroEntropy recipe shape tests. Pins the contracts Codex
 * Round 1 + 2 flagged in the plan-review wave:
 *
 *  - F1: implementation MUST be 'openai-compatible' (not the misspelled
 *    'openai-compat' the original plan draft had).
 *  - F2: base_url_default MUST end with '/v1' so the gateway's
 *    URL-rewrite path replaces /embeddings → /models/embed cleanly.
 *  - reranker touchpoint declared with correct allowlist + payload cap.
