Current

Advanced optimisation passes disabled

8 advanced AST optimisation passes (complete unroll, aggressive inline, loop fusion, etc.) exist but are hardcoded disabled in the default pipeline. Safe to enable experimentally via config.

Current

parallel_for emits incorrect results

Native parallel_for compiles but returns incorrect results. CLI gates it with an error. Parallel execution via safe multicore modes is available for supported workloads.

Current

Advanced OOP falls back to CPython

Simple classes compile natively. Advanced OOP (multiple inheritance, metaclasses, descriptors, complex MRO) triggers honest fallback with reason code.

Current

Stack A legacy tests fail

83 legacy tests fail due to Stack A → Stack B router migration. These are test incompatibilities, not product regressions. Stack B is the supported path.
