"""Tests for the JSON-envelope extractor and the reviewer agent.

The two together replaced the regex `clean_summary` + `looks_like_leakage`
scaffolding that used to live in indicator_summary_job. The extractor is
pure-function so it's covered exhaustively; the reviewer makes an LLM
call and is exercised via the httpx MockTransport that the other
openrouter tests use."""
