-# Mem0 Integration: Dual-Scope Recall + Per-Turn Memory
-
-## Context
-
-Mem0 auto-save works but the integration is missing key features from mem0 best practices: per-turn recall, multi-level scoping, and proper context injection. This causes the bot to "forget" on follow-up turns and not differentiate users.
-
-## What's Missing (vs mem0 docs)
-
-1. **Per-turn recall** — only first turn gets memory context, follow-ups get nothing
-2. **Dual-scope** — no sender vs group distinction. All memories use single hardcoded `user_id`
-3. **System prompt injection** — memory prepended to user message (pollutes session history)
-4. **`agent_id` scoping** — mem0 supports agent-level patterns, not used
-
-## Changes
-
-### 1. `src/memory/mem0.rs` — Use session_id for multi-level scoping
-
-Map zeroclaw's `session_id` param to mem0's `user_id`. This enables per-user and per-group memory namespaces without changing the `Memory` trait.
-
-```rust
-// Add helper:
-fn effective_user_id(&self, session_id: Option<&str>) -> &str {
-    session_id.filter(|s| !s.is_empty()).unwrap_or(&self.user_id)
-}
-
-// In store(): use effective_user_id(session_id) as mem0 user_id
-// In recall(): use effective_user_id(session_id) as mem0 user_id
-// In list(): use effective_user_id(session_id) as mem0 user_id
-```
-
-### 2. `src/channels/mod.rs` ~line 2229 — Per-turn dual-scope recall
-
-Remove `if !had_prior_history` gate. Always recall from both sender scope and group scope (for group chats).
-
-```rust
-// Detect group chat
-let is_group = msg.reply_target.contains("@g.us")
-    || msg.reply_target.starts_with("group:");
-
-// Sender-scope recall (always)
-let sender_context = build_memory_context(
-    ctx.memory.as_ref(), &msg.content, ctx.min_relevance_score,
-    Some(&msg.sender),
-).await;
-
-// Group-scope recall (groups only)
-let group_context = if is_group {
-    build_memory_context(
-        ctx.memory.as_ref(), &msg.content, ctx.min_relevance_score,
-        Some(&history_key),
-    ).await
-} else {
-    String::new()
-};
-
-// Merge (deduplicate by checking substring overlap)
-let memory_context = merge_memory_contexts(&sender_context, &group_context);
-```
-
-### 3. `src/channels/mod.rs` ~line 2244 — Inject into system prompt
-
-Move memory context from user message to system prompt. Re-fetched each turn, doesn't pollute session.
-
-```rust
-let mut system_prompt = build_channel_system_prompt(...);
-if !memory_context.is_empty() {
-    system_prompt.push_str(&format!("\n\n{memory_context}"));
-}
-let mut history = vec![ChatMessage::system(system_prompt)];
-```
-
-### 4. `src/channels/mod.rs` — Dual-scope auto-save
-
-Find existing auto-save call. For group messages, store twice:
- `store(key, content, category, Some(&msg.sender))` — personal facts
- `store(key, content, category, Some(&history_key))` — group context
-
-Both async, non-blocking. DMs only store to sender scope.
-
-### 5. `src/memory/mem0.rs` — Add `agent_id` support (optional)
-
-Pass `self.app_name` as `agent_id` param to mem0 API for agent behavior tracking.
-
-## Files to Modify
-
-1. `src/memory/mem0.rs` — session_id → user_id mapping
-2. `src/channels/mod.rs` — per-turn recall, dual-scope, system prompt injection, dual-scope save
-
-## Verification
-
-1. `cargo check --features whatsapp-web,memory-mem0`
-2. `cargo test --features whatsapp-web,memory-mem0`
-3. Deploy to Synology
-4. Test DM: "我鍾意食壽司" → next turn "我鍾意食咩" → should recall
-5. Test group: Joe says "我鍾意食壽司" → someone else asks "Joe 鍾意食咩" → should recall from group scope
-6. Check mem0 server logs: GET with `user_id=sender` AND `user_id=group_key`
-7. Check mem0 server logs: POST with both user_ids for group messages
