+# Test resource settings for the locally rebuilt x86-64-v3 package set.

 # Selecting x86-64-v3 changes every affected derivation, so the normal
 # nixpkgs binary cache cannot be used and upstream test suites run locally.
 # The jeeves builder uses /tmp/nix-builds so filesystem tests run on tmpfs
 # instead of ZFS with normalization=formD and utf8only=on; those tests remain
-# enabled. The remaining workarounds cover UDP readiness, resource-sensitive
-# parser and nested-worker races, and mismatched timeout clocks, plus
-# architecture-dependent floating-point differences whose risk we accept for
-# our workloads. Keep these exceptions visible until their causes are fixed.
+# enabled. This overlay no longer excludes any tests. The remaining settings
+# bound nested worker concurrency and allow time for worker startup under load.
+# Test repairs and their validation are indexed in patches/README.md.
