+#### Testing
+
+- Add local Release and ASan/UBSan commands in `tests/run_core_ci.sh` for the
+  core archive, all six core regression suites, and qmake/standalone tree tests,
+  with separate build directories and fatal test/sanitizer failures.
+- Verify clean Release and ASan/UBSan builds: each passed 2,397 QtTest checks
+  without skips plus qmake and standalone tree tests. Local leak checking is
+  blocked by ptrace. Validate shell syntax and build-failure propagation.
+
 #### Fixed
 
 - Read attribute definitions, defaults, and assignments across physical lines.
