 # Current tasks
 
+## Tmp file cleanup (stale filepond + _trash)
+- [x] Session-based detection: check manifest session_id against PHP session files
+- [x] DB-based detection for _trash: check thesis_files row still exists
+- [x] Time-based fallback: >2h filepond, >30d trash
+- [x] admin cleanup-stats.php: stale vs active breakdown with sizes
+- [x] admin cleanup-tmp.php: smart cleanup with detailed JSON response
+- [x] admin index: Nettoyer button + dialog with stats and cleanup trigger
+- [x] .gitignore: exclude tmp/filepond/* and tmp/_trash/*
+- [ ] Deploy: just deploy
+
+## Dialog & trash page margins
+- [x] Add admin-dialog__body CSS rule with padding + margin resets
+- [x] Add admin-dialog__stats + admin-dialog__hint classes
+- [x] Fix admin-dialog__alert p margins (not-last-child gets bottom margin)
+- [x] Add horizontal margins to .admin-main--list > direct children (trash page forms, tables, flash msgs)
+- [x] Clean up tmp-cleanup dialog inline styles → CSS classes
+
 ## Deploy exclusions
 - [x] Exclude storage/tmp/ (not just filepond/*) to skip _trash dirs with bad perms
 - [x] Exclude storage/documents/ and storage/theses/ from rsync deploy
