-The I/O view provides the main view aggregate view into test input and
-program output. Used time/memory per test case are appended to the output.
-The |cp-panel| offers more fine-grained analysis into each test case.
+The I/O view provides lightweight test feedback in persistent side splits.
+All test outputs are concatenated with verdict summaries at the bottom.
+The |cp-panel| offers more fine-grained analysis with diff modes.

+The output split shows:
+1. Concatenated test outputs (separated by blank lines)
+2. Space-aligned verdict summary with:
+   - Test number and status (AC/WA/TLE/MLE/RTE with color highlighting)
+   - Runtime: actual/limit in milliseconds
+   - Memory: actual/limit in megabytes
+   - Exit code (with signal name for crashes)
