+- **The 105 CKA solutions rewritten in 2026.10.27.1 are proven**: `./ksim audit` ran each on a
+  host of its own on v1.37, as the solution shows it, every edit by hand done by its script. All
+  105 seed cleanly, score nothing untouched and reach full marks. The README's audit record says
+  so. No task's setup or checks have changed since the audit of 2026-10-19, nor have the other 42
+  solutions.
