+===========================================
+ANALYSIS SUMMARY (Last updated: December 2025)
+===========================================
+
+OVERALL STATUS:
+- The project has made substantial progress towards making production usable
+- Core IMAP functionality is implemented with service classes and scheduled tasks
+- Email extraction infrastructure is in place with multiple extractors
+- History tracking system is complete for emails
+- Testing infrastructure is solid with good coverage
+
+KEY COMPLETED AREAS:
+✅ History table implementation (email tracking complete)
+✅ Update-imap core functionality (folders, inbox, sent processing)
+✅ Scheduled folder processing (new folders, inbox, sent via scheduled-imap-handling.php)
+✅ Email extraction framework (plain text body, PDF attachments, AI prompts)
+✅ Email extractor service classes and scheduled tasks
+✅ AI integration with OpenAI
+✅ Basic GUI for replying to threads
+
+MAIN GAPS REMAINING:
+❌ HTML body extraction from emails
+❌ Image and other attachment extraction (OpenAI vision integration)
+❌ Manual trigger for extractions from overview page
+❌ Old threads cleanup and public label access
+❌ Public-facing views and front page
+❌ Template system for common responses
+❌ Rich text editor for replies (currently basic textarea)
+❌ Attachment upload functionality for replies
+❌ Database backup scheduling
+❌ Advanced thread concepts (notifications, automatic follow-up)

 Goal: make production usable
 
 
 - [ ] Add history table including who did what
+    STATUS: Email history is COMPLETE. Thread history infrastructure exists but "system" user handling needs work.
+    IMPLEMENTATION: ThreadEmailHistory class, thread_email_history table (migration 008)
     - [ ] Special users for "system". Must point to some usage. Then handled in display.
+        NOTE: Infrastructure exists but not fully integrated for system user display
     - [x] History table for emails
+        COMPLETE: All email actions are tracked in thread_email_history table
         Example actions
         - [x] Email received

     - [ ] Open some labels to public
+        NOTE: No public access functionality implemented yet
     - [ ] Clean up old threads by archiving them
+        NOTE: ThreadFolderManager has archiveThreadFolder() but no scheduled cleanup task
 - [ ] Update-imap - remake
+    STATUS: Core functionality COMPLETE. Service class migration incomplete for scheduled tasks.
+    IMPLEMENTATION:
+    - Service classes: ImapConnection, ImapFolderManager, ImapEmailProcessor, ThreadEmailDatabaseSaver
+    - Scheduled handler: scheduled-imap-handling.php (calls createFolders, processSentFolder, processInbox)
+    - Functions in update-imap-functions.php work but need to be wrapped in service classes
+    - Tests exist: ImapConnectionTest, ImapFolderManagerTest, ImapEmailProcessorTest
+
     - [x] Direct access should list folders
     - [x] Read per folder
     - [x] Database table with status for imap folders
