"""Diverse-topic evaluation harness for the three default-on Printing Press
sources (arxiv, techmeme, trustpilot).

Two layers:

1. Deterministic fire/quiet matrix over five diverse topics drawn from real
   run history. Asserts each source's *gating* decision without calling any CLI
   -- this is the part that proves "Trustpilot fires only on company topics" and
   "arXiv stays quiet on stale/off-topic matches".

2. Opt-in --live mode (set LAST30DAYS_EVAL_LIVE=1) that actually invokes the
   installed CLIs against the same topics, prints a sample for human review, and
   asserts the negative controls stay quiet. Skipped by default so CI stays
   deterministic and offline.
