# #region Test.LLMAnalysisService.Coverage [C:3] [TYPE Module] [SEMANTICS test,llm,analysis,coverage,edge]
# @BRIEF Additional coverage tests for service.py — _launch_and_login, capture_dashboard_chunks,
#   capture_dashboard, LLMClient edge cases, DatasetHealthChecker edge cases.
# @RELATION BINDS_TO -> [LLMAnalysisService]
# @TEST_EDGE: launch_login_direct_form -> Direct form login fallback (no username field found)
# @TEST_EDGE: launch_login_redirect_to_login -> Dashboard navigation redirects to login page
# @TEST_EDGE: chunks_cdp_fallback -> CDP capture fails, falls back to Playwright
# @TEST_EDGE: chunks_no_tabs -> No tabs found, captures full page as single chunk
# @TEST_EDGE: json_completion_rate_limit -> RateLimit error triggers retry delay parsing
# @TEST_EDGE: json_completion_json_mode_fallback -> JSON mode fails, falls back to plain
# @TEST_EDGE: health_chart_data_list_result -> chart data returns list instead of dict
