Twenty-three tests imported helpers from sibling test modules by dotted path (tests.run_agent.test_run_agent, tests.cli.test_cli_init, tests.gateway.test_42039_duplicate_user_message); those follow the moves and renames. The run_agent autouse fixture that zeroes jittered_backoff now covers all of tests/agent, where one pre-existing test asserts the real backoff is positive — it opts out via a real_retry_backoff marker, the same pattern real_concurrent_gate and real_agent_prewarm use.
