Phase 1: Core Client
- New class-memanto-client.php: Singleton PHP client for MEMANTO API v2
- Health check with 5-min transient caching
- Agent CRUD (ensure, activate, deactivate sessions)
- Memory operations (remember, batch_remember, recall, recall_recent)
- Auto re-activation on expired session tokens (401 retry)
Phase 2: Write-Through Memory Hooks
- New class-memanto-context-enhancer.php: Orchestrates remember/recall
- Fires on: user message, plan generated/approved/rejected,
section written, block refined, config saved, session start/end
- All hooks via do_action() — zero coupling to MEMANTO when disabled
Phase 3: Context Enrichment
- Context builder injects recalled memories into AI prompts
via build_memanto_context() in build_working_context()
- 3-recall strategy: recent post memories, semantic search, user preferences
- Deduplication by content hash
Phase 4: Cross-Session Restore
- New REST endpoints: /memanto/restore, /memanto/preferences
- restore_session() recalls 15 recent memories + user preferences on editor load
- build_session_restore_message() creates AI-ready system message
- get_user_preferences_for_new_post() extracts tone/audience/length/language
- Frontend: 🧠 Restored badge in status bar with memory count tooltip
- Preference carry-over: auto-fills post config from stored user preferences
- deactivate_session() called on session end (triggers MEMANTO summary)
- Badge clears on new conversation start
Settings UI:
- MEMANTO Context Keeper section with enable toggle, URL, API key, test connection
- Settings registered via class-settings-v2.php + tab-memanto.php view
Graceful degradation: all MEMANTO calls guarded by is_active(),
frontend catches silently, plugin works identically when disabled.
