+### 29.15 Ammunition readout
+
+Active ammunition skills show remaining rounds and magazine capacity below the segmented bar (§10), including
+Laterano's extra rounds and refills. The renderer reads the existing exact snapshot counts rather than estimating
+them from SP. Missing ammunition snapshots, preparation and death hide the number. Dense magazines retain their
+numeric readout when the renderer omits cell separators. Combat rules and golden results are unchanged.
