     TreatWarningsAsErrors is ON for every project, src/ and tests alike (#766 ratchet). The solution builds with
     0 warnings since #725 (xUnit1051 etc. cleaned), so any new warning, including analyzer ones, now fails the
-    build instead of accumulating. The 61 src/ projects also still set it in their own csproj (#606); that is
-    redundant but harmless. A project that genuinely needs an exception should suppress the specific warning
-    via NoWarn, not turn this off.
+    build instead of accumulating. This is the ONLY place it is set: the per-project copies (#606) were removed
+    (#768), so do not add it back to a csproj. A project that genuinely needs an exception should suppress the
+    specific warning via NoWarn, not turn this off (only the throwaway tools/mem-probe probes opt out).
