- * Test Summary Script for Agentic Knowledge
- * Runs tests and provides an overview of results from all packages

+ *
+ * Runs the test suite for every workspace package plus the root e2e suite and
+ * prints an aggregated summary.
+ *
+ * Design notes:
+ * - Child output is streamed straight through to this process's stdout/stderr
+ *   so failing assertions, stack traces and vitest diffs always end up in the
+ *   CI log. It is also buffered so the counts can be parsed for the summary.
+ * - Success/failure is decided by the child *exit code*, never by parsing.
+ *   Parsing is best-effort presentation only; a summary line we fail to
+ *   recognise can therefore never turn a red run green.
