⚠️ Bug: PROXYSQLTEST 52 test requires a DEBUG build to pass
case 52 in lib/ProxySQL_Admin_Tests2.cpp is compiled only inside #ifdef DEBUG; on a non-DEBUG binary the outer default: branch replies with send_error_msg_to_client(...,"Invalid test"), so mysql_query(admin, "PROXYSQLTEST 52") returns an error and the new test_admin_hostgroup_balancing-t assertion command_rc == 0 (and the follow-on state checks) will fail. The test is registered only in mysql84-g1; unless that group runs a DEBUG/GCOV-instrumented build, this TAP will red CI. Confirm mysql84-g1 uses a DEBUG binary, or gate the test on debug availability (e.g. skip when the command returns "Invalid test").

Learning: In ProxySQL's TAP test suite, resource leaks (e.g., not calling mysql_close() on early return paths) are commonly tolerated because test processes are short-lived and OS frees resources on exit. This pattern applies to all C++ test files under test/tap/tests. When reviewing, recognize this as a project-wide test convention and focus on test correctness and isolation rather than insisting on fixing such leaks in these test files.

Learning: When using GitHub-flavored Markdown headings, be aware that an em-dash surrounded by spaces (written as ` — `) affects the generated anchor/slug: GitHub replaces spaces with hyphens and removes non-alphanumeric punctuation, which can produce double hyphens (e.g., `## Foo — bar` → anchor `#foo--bar`, not `#foo-bar`). If you reference these anchors (e.g., internal links), ensure the expected slug matches this behavior.

Learning: When reviewing GitHub-flavored Markdown links/anchors, remember that heading-to-anchor slug generation treats spaces as hyphens and removes punctuation. If a heading contains an em-dash surrounded by spaces (e.g. ` — `), the slugs can legitimately include a double hyphen where the two surrounding space-runs become `-` on either side of the removed em-dash (e.g. `...vocabulary--read...`). Do not flag double-hyphens in anchor links for em-dash-containing headings as errors; they reflect GitHub’s correct slug behavior.

Define the required runtime rows exactly.
The PR objective requires an empty configuration table and exactly three OFFLINE_HARD runtime rows. “Return to the starting state” permits a different runtime result. State the required row count and status here.

Rename the constant to UPPER_SNAKE_CASE.
kTestHostgroup does not follow the required constant naming format. Rename it to TEST_HOSTGROUP and update all references.
As per coding guidelines, “Constants and macros must use UPPER_SNAKE_CASE”.

Stop when the initial state is invalid.
If either initial hostgroup check fails, the test still runs PROXYSQLTEST 52. The command can change the unexpected state that the test just reported. Skip the remaining three planned checks and close admin when either precondition fails.
Proposed fix
ok(before_runtime_ok && before_runtime == 0,
"Hostgroup %u is absent from runtime_mysql_servers before PROXYSQLTEST 52", kTestHostgroup);
+ if (!before_admin_ok || before_admin != 0 || !before_runtime_ok || before_runtime != 0) {
+ skip(3, "Hostgroup must be absent before PROXYSQLTEST 52");
+ mysql_close(admin);
+ return exit_status();

When TAP_ADMINHOST differs from TAP_HOST, this connects to the frontend host while using the admin port and credentials, so the new TAP fails before exercising PROXYSQLTEST 52 (or reaches the wrong ProxySQL instance). CommandLine::getEnv() stores TAP_ADMINHOST in cl.admin_host; use that field here instead of cl.host. The isolated CI environment currently masks this because both variables are set to proxysql.
