Quick Answer
Angular CD lifecycle phases: 1) Mark view dirty (async event fires), 2) ApplicationRef.tick() starts CD from root, 3) For each component in tree: check host bindings, run ngDoCheck, check child components recursively, 4) Update DOM for changed components. OnPush skips the subtree unless input changed. ngAfterViewChecked fires after each CD cycle where a view is checked.
Answer
Angular runs two phases: Check phase: Verifies bindings. Update phase: Applies DOM updates and triggers child checks. This ensures UI consistency.
