The Rust React Compiler in Next 16.3.1 refuses to compile the 2730-line
Home component in frontend/src/app/page.tsx and reports nothing at all:
the build prints the option as enabled, exits 0, and tests stay green
while zero memoization is applied. Six configurations were tried; the
compiler optimized 44 functions elsewhere (including 2 smaller ones in
page.tsx itself) but never Home, and panicThreshold: "all_errors" is a
no-op on the Rust port, so the failing construct could not be located.
The reactCompiler config is therefore rolled back per the task's
stop-loss clause while the Next 16.3.1 upgrade is kept. BUG-255 records
the silent-bailout trap so a future attempt does not mistake "option
enabled and build green" for "compiler actually working". BLOCKED.md
records the two paths out, both of which need authorization: adding
babel-plugin-react-compiler to get diagnostics, or splitting Home.
No business code, test, or CI file was touched.
