Test harnesses added for all remaining AVM ISA ports:
- C (9 tests): arithmetic, saturation, comparison, overflow, control flow, locals
- C++ (9 tests): same test suite with std::optional-based error handling
- Scala (9 tests): functional style with Option return
- Fortran (4 tests): add, div, saturation, control flow (minimal Fortran test)
- Octave/MATLAB (4 tests): basic operations test
Milestone: 10/12 ports have test harnesses. Coq still pending.
Python port rewritten to match spec:
- Added Q0_16, PUSH_Q0, PUSH_BOOL as separate opcodes
- Added V6 comparison (lt_q16_v6)
- Added floor division (Lean Int.ediv)
- Added stack depth limit (AVM_MAX_STACK = 1024)
- Added type checking in exec_prim
- All 10 tests passing
Go AVM port: added test_avm_test.go with 8 test cases
Milestone: Python → ✅, Go → 🔄
