Codex found two more once the config-guard bug was fixed (Opus concurred on #2):
1. panels.js _buildPluginCard built the Open button + enable toggle with inline
onclick/onchange that interpolated tab.path / plugin.key into a JS-string-in-
attribute context — HTML-escaping is insufficient there (quote breakout).
Now rendered inert + bound via addEventListener with RAW closure values.
2. tab.path was unvalidated. Added _VALID_PLUGIN_TAB_PATH (^/[A-Za-z0-9._~/-]{0,255}$)
in load_plugins() — absolute, no quotes/query/fragment/control chars.
Also Opus nit: deep-merge now coerces dashboard_plugins values to bool + str keys.
Regression tests added for both.
