Code Review

This pull request updates code comments, docstrings, and field descriptions across several files to document compatibility changes for Home Assistant 2026.6+. Specifically, it notes that the show_advanced_options parameter is treated as a no-op in HA 2026.6+ (retained temporarily for older versions) and updates dashboard resource management documentation to reflect that UI exposure is now enabled by default. No review comments were provided, and there is no additional feedback to address.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Thanks for this, @nightcityblade, and welcome aboard.

This cleanly closes #1532. Both acceptance criteria are met: the ha_config_list_dashboard_resources docstring no longer claims advanced mode is required for the Resources UI, and you recorded a clear decision on show_advanced_options (keep + no-op note) at every layer the issue listed — rest_client, the subentry-flow helper, and both tool Field descriptions. I swept src/ and there are no remaining stale "advanced mode" references. The diff is tight and fully in scope, and keeping the param rather than ripping out the plumbing is the right, lower-risk call for now.

Approving as-is. Two entirely optional wording nits if you ever revisit this area — nothing to change for this PR:

• The rest_client.py comment is the only one of the four notes missing the "before HA 2027.6" deadline the others carry.
• "pending removal before HA 2027.6" is accurate; it could read a touch clearer as "drop this plumbing before HA removes the property in 2027.6."

Thanks again for the careful, well-tested fix.
