AceGUI-3.0/widgets/AceGUIContainer-BlizOptionsGroup.lua: the Constructor parented its frame to the global InterfaceOptionsFramePanelContainer, which is nil at AceGUI widget-construction time on the CoA reworked FrameXML. Guard with 'local _parent = InterfaceOptionsFramePanelContainer or UIParent' and pass _parent to CreateFrame so addons that register a Blizzard Interface Options panel don't error out during load. AceConfig-3.0/AceConfigDialog-3.0/AceConfigDialog-3.0.lua: :AddToBlizOptions used the Dragonflight+ Settings.* API (GetCategory, RegisterCanvasLayoutCategory, RegisterCanvasLayoutSubcategory, RegisterAddOnCategory). The Settings table doesn't exist on the 3.3.5-based CoA client, so every AceConfig-driven options panel errored the moment it was registered. Wrap the whole Settings.* block in 'if Settings and Settings.GetCategory then ... else ... end' and fall back to the WotLK-era InterfaceOptions_AddCategory(group.frame) after stamping the category name via group:SetName(name or appName, parent). Both retail and CoA paths now work; behaviour on retail is unchanged. luac -p passes on both files. README CoA-compat patches table updated (entries 2 and 3). This bundle is the source-of-truth for the Exiles/coa-* forks; the propagation to bartender / quartz / shadowedunitframes / ai-voiceover / etc. bundled Ace copies is handled separately.
