+### ✅ Phase 5 — Prediction Engine
+- [x] Write `core/predictor.py`
+  - [x] `hot_numbers(game_id, last_n=100)` — top-frequency + most-frequent bonus
+  - [x] `due_numbers(game_id)` — highest gap numbers from pool
+  - [x] `weighted_random(game_id)` — numpy weighted choice (min weight 1 for unseen)
+  - [x] `monte_carlo(game_id, simulations=10000)` — tally-based selection
+  - [x] `positional_pick(game_id)` — per-position best with dedup
+  - [x] All strategies: random fallback on empty DB
+- [x] Write `ui/predictor_ui.py`
+  - [x] Game + strategy + ticket count dropdowns
+  - [x] Generate button (disables during generation)
+  - [x] Treeview results: #, zero-padded numbers, bonus
+  - [x] Save to DB (insert_prediction per ticket) + Clear
+  - [x] Strategy description label
+- [x] 18 tests — all 5 strategies × validity + empty DB + edge cases (124/124 total)
