+### ✅ Phase 19 — Dashboard Overdue Alert + DB Backup
+- [x] Add `backup_db(dest_dir=None) -> str` to `db/database.py` — copies live DB to timestamped file, creates dest dir if needed
+- [x] Add `restore_db(source_path: str) -> None` to `db/database.py` — overwrites live DB with backup file, raises FileNotFoundError if missing
+- [x] Update `ui/dashboard.py`
+  - [x] Import `gap_analysis` from `core.analyzer`
+  - [x] Add "Most Overdue Numbers" section below Hot Numbers
+  - [x] `_refresh_overdue()` — top-5 highest-gap numbers per active game, shown as orange-highlighted `BallsBar` with gap counts
+  - [x] Called from `refresh()`
+- [x] Update `ui/settings.py`
+  - [x] Import `backup_db, restore_db` from `db.database`
+  - [x] Add "Database Actions" section with Backup DB + Restore DB buttons
+  - [x] `_backup_db()` — runs backup, shows path in success dialog
+  - [x] `_restore_db()` — file dialog, confirm prompt, restores, advises restart
+- [x] Write `tests/test_backup.py` — 10 tests (361/361 total passing)

+### ✅ Phase 18 — Draw CSV Import
+- [x] Write `core/importer.py`
+  - [x] `_parse_date(text)` — accepts ISO (YYYY-MM-DD), US slash (MM/DD/YYYY), US dash, day-first formats
+  - [x] `_is_header(row)` — heuristic: first cell is not a valid date
+  - [x] `_parse_row_lottosight` — handles LottoSight's own export format (Game, Date, Numbers, Bonus, …)
+  - [x] `_parse_row_generic` — handles wide format (Date, N1, N2, …) and packed format (Date, "N1,N2,…")
+  - [x] `import_draws_csv(game_id, filepath) -> {added, skipped, errors}` — validates count + range, calls `insert_draw`, deduplicates via existing DB logic
+- [x] Update `ui/settings.py`
+  - [x] Add `filedialog` import
+  - [x] "Import CSV" button on every game row (builtin and custom)
+  - [x] `_import_csv(game_id, game_name)` — file dialog → import → show summary with error preview → refresh games
+- [x] Write `tests/test_importer.py` — 23 tests (351/351 total passing)

 ### ✅ Phase 17 — Predictor Power Features
 - [x] Add `quick_pick(game_id, exclude=None)` to `core/predictor.py` — pure random, no draw history required
 - [x] Add `exclude: set | None = None` parameter to all 5 existing strategies + `_random_ticket` + `_fill_to_count`
