+
+Refreshes the pinned engine to **Flutter 3.44.6** (`ee80f08b`, Dart 3.12.2).
+
+### Engine / SDK
+- Bumped `bin/internal/flutter.version` to `ee80f08b` (Flutter 3.44.6) and
+  `bin/internal/engine.version` to `v1.0.1-flutter3.44.6`.
+- Rebuilt and origin-signed all six engine artifact variants from the 3.44.6
+  source tree, against tvOS SDK 26.5 (Xcode 26.6).
+- All 17 tvOS engine patches apply unchanged: the 3.44.5 → 3.44.6 delta touches
+  only `flutter_tools` and the Android Gradle plugin, so no patched file moved.
+- Dart revision is unchanged from 3.44.5, so this is not an SDK-hash-breaking
+  roll — the artifacts were rebuilt anyway to keep the engine tag and the SDK
+  pin in lockstep.
+
 ### Fixed
+- **Apps no longer crash on first frame on tvOS simulators older than 26.** The
+  simulator engine embedded Impeller metallibs compiled for the *iOS* simulator
+  (target triple `air64-apple-ios13.0.0-simulator`), because the shader build
+  assumed the tvOS simulator would load iphonesimulator libraries fine — it runs
+  on the host Mac GPU, after all. Metal actually validates the library's target
+  platform when a pipeline is created, so on a tvOS 17.5 simulator every one of
+  the ~60 render pipelines failed with `Target OS is incompatible` and the engine
+  aborted with a `raw_ptr` check failure. tvOS 26 tolerates the mismatch, which
+  is why it only showed up on older runtimes. The simulator engine is now built
+  against the AppleTVSimulator SDK (`air64-apple-tvos13.0.0-simulator`). Device
+  builds were never affected. Requires the engine bump to
+  `v1.0.1-flutter3.44.6`. (#38)
 - **Debug builds launched outside `flutter-tvos run` on a physical Apple TV no
   longer crash during plugin registration.** The debug engine refuses to start
   without an attached debugger, so the plugin registry hands back nil

+### Upstream fixes picked up
+- Flutter 3.44.6 hotfixes for a native-assets crash on Linux custom devices and
+  for jniLibs staging in the Android Gradle plugin. Neither affects tvOS builds;
+  they ship because the SDK pin moves as a whole.
