+### 28.9 Preserve facing during pushes and pulls — #418 / PR #427
+
+Ported from [PR #427](https://github.com/sganggs/Stronghold-Protocol/pull/427) by @YinqiMargatroid.
+Successful pushes/pulls mark their displacement events `keepFacing` so the renderer retains pre-hit facing
+while waiting for the endpoint snapshot and throughout the slide. Raw displacement and explicit
+`keepFacing: false` retain the old directional behavior. Position, distance and unbalance time are unchanged.
+The contributor's source clips and their limitations are retained in research 13; those observations were not
+independently replayed for this port. **[ASSUMED]** other push sources and pulls against the target's old facing
+share the examples' display behavior; the drag template alone cannot establish that engine rule.
+Tests cover real push/pull skill paths, default/override metadata, snapshot reversal, and an earlier attack
+arriving after slide prestart in either field direction. Golden metadata deliberately omits the display flag.
