React Native: Framework Headers Hardening and Android Performance Push
A broad cleanup moves native headers to stable umbrella imports for strict API enforcement, while Android work cuts mount costs, idle frame work, and C++ build times. Standalone fixes end Inspector remounts and add missing web globals.

Hello, it's Tuesday, September 29th, 2026.
The lead pattern today is hardening, not features: a coordinated push to route native framework headers through public umbrellas for strict API checks, paired with Android efficiency work and a few high-impact developer experience fixes.
First, the header migration. About ten changes touch text layout, scroll view, text input, root, animated, animation backend, and code generation output. The idea is the same throughout: public headers now include through stable umbrellas for graphics, core rendering, and native modules, while implementation helpers…
Second, Android runtime and build cost. Commit 52c576b batches Fabric mount integers to Java in a single bridge call, cutting mount execution time up to twelve percent in large commits. Commit 8baeb2d, behind an experimental flag, stops re-arming the dispatch UI frame callback while idle, so static screens drop to…
Finally, tools and web parity. Commit d194d8b fixes the Element Inspector so toggling touch targets no longer remounts the app and loses navigation state. Pull request 58736 exposes structured clone and D O M exception globally, pull request 58718 restores lazy chunk evaluation on…
