Docs review — ✅ Approve

Android SDK + UIKit v6 card-messages/streaming docs (11 files, +571/-306). It deletes interactive-messages.mdx but correctly adds a redirect for it, and the API surface checks out against the Android Chat SDK 5.0.4 and UIKit v6 source. Structurally clean.

✅ What passed (verified)

• Deletion handled correctly: sdk/android/v5/interactive-messages.mdx is deleted, removed from nav, and a redirect was added → /sdk/android/v5/send-message (redirects +1; 0 unredirected removed URLs). 👍
• Build / nav: 0 unresolved nav refs, 0 orphans. New campaigns.mdx is wired into nav (docs.json:4189); the new SVG is referenced in message-structure-and-hierarchy.mdx and is well-formed XML.
• SDK card-streaming API (verified against chat-sdk-android 5.0.4):
  • addAIAssistantListener example uses the correct CometChat.AIAssistantListener() base class in both Java and Kotlin (no CometChat.CallListener mistake).
  • Card event classes (AIAssistantCardStartedEvent/ReceivedEvent/EndedEvent), getCardId(), getCard() all exist.
  • CardMessage accessors confirmed: getCard()→JSONObject, getFallbackText()→String, getTags()→List<String>, getText()→String; onCardMessageReceived(CardMessage) exists.
  • Kotlin examples use correct (name: Type) parameter syntax.
• UIKit (verified against uikit-android v6 branch): setLoadLastAgentConversation/loadLastAgentConversation confirmed in both chatuikit-compose and chatuikit-kotlin CometChatMessageList — the migration row in message-list.mdx is accurate. CometChatUIEvent.CardActionClicked matches the file's sibling event-naming convention.
• Content coherence: message-structure-and-hierarchy.mdx adds "card" as category maple-theme #3 with a ## Card section, the new diagram, and correct cross-links to send-message#card-message / receive-messages.
• Broken links: the 2 the analyzer flagged (/sdk/android/calling-setup, /sdk/android/default-calling) are in unchanged files — pre-existing, out of scope.

🟡 P2 — one verification gap (author/SDK team to confirm)

The card-action class com.cometchat.cards.actions.CometChatCardActionEvent (cast target for event.actionEvent, with fields action/elementId/cardJson) lives in a separate com.cometchat.cards rendering module that isn't checked out in my workspace, so I couldn't confirm it from source. Its field names exactly match the verified Flutter CometChatCardActionEvent, so it's almost certainly correct — just worth confirming the exact class path and the CardActionClicked UI-event symbol against the shipped cards library.

Otherwise excellent work, and a good model for handling page deletions (redirect included).
