+### ✅ Phase 22 — Incremental VA Fetch + Top Prize + Dashboard Filter + Auto-Check
+- [x] Incremental VA fetch in `core/fetcher.py`
+  - [x] `_fetch_va_lottery()` calls `get_last_draw()` for last known date
+  - [x] Breaks out of parsing loop when `draw_date <= last_date` (data is newest-first)
+  - [x] Result: subsequent fetches only download new records, not all 10K+ rows
+- [x] `top_prize` column in `db/database.py`
+  - [x] Added `top_prize TEXT NOT NULL DEFAULT ''` to `CREATE TABLE games`
+  - [x] ALTER TABLE migration for existing databases (checks via `PRAGMA table_info`)
+  - [x] Updated `_seed_games()` with prize strings for all 5 builtin games
+  - [x] Back-fills `top_prize` for existing rows where empty (safe to re-run)
+- [x] Dashboard game filter in `ui/dashboard.py`
+  - [x] `_filter_var` combobox at top ("All Games" + active game names)
+  - [x] `_update_filter_options()` — keeps combobox in sync with active games
+  - [x] `_filtered_games()` — returns subset based on selection
+  - [x] Last Draws, Hot Numbers, Overdue sections all respect filter
+- [x] Top prize display in last-draw cards (`ui/dashboard.py`)
+  - [x] Shows "Top prize: $X" in purple above draw date if `top_prize` is set
+- [x] VA source names added to `ui/statusbar.py` `_SOURCE_NAMES`
+- [x] `append_match_alert(msg)` method added to `StatusBar`
+- [x] Auto-check predictions after fetch in `main.py`
+  - [x] `_check_predictions_vs_latest()` — compares all saved predictions against newest draw per game
+  - [x] Called from `_on_fetch_done()` when `total_added > 0`
+  - [x] Status bar shows alert when ≥1 prediction matches ≥2 main numbers or bonus
+- [x] `tests/test_phase22.py` — 14 tests (403/403 total passing)

 ### ✅ 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
