+
+## Summary
+
+Completed quick task: Added a "尾首概率" (Tail-Head Probability) dialog to the history page.
+
+### Changes
+- `application/admin/model/History.php` — Added `getTailHeadProbability()` method that analyzes consecutive period transitions of the special code (num7), calculating the probability of tail (ones digit) and head (tens digit) remaining the same
+- `application/admin/controller/History.php` — Added `tailHeadProb` endpoint + added to `$noNeedRight`
+- `application/admin/view/history/index.html` — Added toolbar button with `btn-tailheadprob` class
+- `public/assets/js/backend/history.js` — Added click handler + `showTailHeadProbabilityDialog()` with period selector (30/50/100/200)
+
+### Implementation details
+- Tail = num % 10 (个位), Head = floor(num / 10) (十位)
+- Only counts valid transitions (both numbers in 1-49 range)
+- Displays probability as percentage with period count and transition count
