 ## Why thresholds differ per repo
 
 These are *floors*, not targets — set near each repo's actual coverage at
 the time CI was set up, then only ever raised (never silently lowered) as
-the repo's test suite grows. A wide range (38% in `shrike` vs 80% in
-`sparrow`) reflects real differences in how much of each repo is
-exercised by unit tests vs. requiring live provider credentials
-(`test-live` targets) or manual verification — it is not an oversight.
