Function runNoPanic

empty_key_path_test.go:23–31

Regression coverage for the empty-string key path component hazard (hazard-sweep finding). A caller passing "" as a path component used to trigger `runtime error: index out of range [0] with length 0` at the unguarded `keys[i][0]` / `p[level][0]` dereference sites in searchKeys, EachKey, createInser

// runNoPanic executes fn and fails the test if it panics, returning the
// recovered value so callers can also assert on the post-fix result.
func runNoPanic(t *testing.T, name string, fn func()) {

	defer func() {
