include/ is the single vendored Static Hermes header surface used by both Apple and Android builds. It comes from DjDeveloperr/build-hermes and must stay in sync with the Hermes binaries under Frameworks/ and platforms/android/test-app/runtime/src/main/libs/hermes/.

Android still accepts the historical SHERMES engine selector so existing test/build scripts keep working, but it is now only an alias for HERMES. Both selectors compile the same adapter and link the same Static Hermes artifact.
