Heat oven to 325°F. Grease a 9-inch springform pan, line bottom with parchment, and wrap the outside with foil.
Combine cookie crumbs, crust sugar, and melted butter until evenly moistened. Press firmly into the pan bottom.
Bake crust 8–10 minutes, then cool on a rack while you make the filling.
Beat cream cheese on medium speed until completely smooth, about 2 minutes.
Mix in filling sugar and salt until no grainy bits remain. Scrape the bowl well.
Blend in sour cream, vanilla, and flour just until combined; do not overmix.
Add eggs one at a time on low speed, beating only until each disappears.
Pour batter over the crust and tap the pan to release air bubbles.
Bake 55–65 minutes until edges are set and the center still jiggles slightly.
Turn off oven, crack the door, and cool 1 hour. Then cool to room temp and chill at least 4 hours.
Warm caramel until pourable. Spread over the chilled cheesecake.
Melt chocolate chips with heavy cream until smooth. Drizzle over caramel, then top with pecans. Chill 15 minutes to set.
