"""Tests for tools/job_key.py - the canonical seen_jobs.json key function.

/scrape's key rule was prose only, so runs slugified inconsistently and the
state file accumulated two failures: keys carrying "/", "," and "&" that break
the archive-folder path `/apply`/`/outcome` derive from company+role, and the
same job stored twice under two different truncations of a long title. These
pin the fix - a pure, deterministic function of company+title(+url) - and the
audit that finds both failure classes in an existing file.
