 # Current tasks
 
+## acces.php conflict marker cleanup
+- [x] Remove 206k lines of nested jj conflict markers from acces.php (resolved from clean nzllwsxo base)
+- [x] Restore missing features: create-result dialog, locked_year field, auto-generated password UI, file restrictions section, admin TOC wrapper
+
 ## Save fixes (files disappearing on edit/terminer)
 - [x] Fix: note_intention deleted on save — handleFilePondSingleFile treats existing DB id as new upload, deletes existing, then can't re-process (integer vs hex mismatch)
 - [x] Fix: cover removal now uses trash, same hex-vs-integer guard as note_intention

+## File browser fixes
