# Milestone: AVM ISA 1:1 Port Coverage
|
|
|
|
**Goal:** Every language with an LSP installed on the build infrastructure
|
|
must have a complete, Lean-validated AVM ISA v1 port with cross-implementation
|
|
test harness.
|
|
|
|
## Coverage Matrix

## 1:1 Verification Protocol
|
|
|
|
For each port, run the same test vector through every implementation:
|
|
|
|
```python
|
|
test_vector = [
|
|
# (op, a, b, expected_q16)
|
|
("add", 5*65536, 3*65536, 8*65536), # 5 + 3 = 8
|
|
("sub", 10*65536, 3*65536, 7*65536), # 10 - 3 = 7
|
|
("mul", 5*65536, 3*65536, 15*65536), # 5 * 3 = 15
|
|
("div", 10*65536, 2*65536, 5*65536), # 10 / 2 = 5
|
|
("lt", 5*65536, 3*65536, False), # 5 < 3 = false
|
|
("lt", -5*65536, -3*65536, True), # -5 < -3 = true
|
|
("add_sat", cload_max-1, 2, cload_max), # saturation
|
|
("div_neg", -5*65536, 3*65536, -1*65536), # floor division: -5/3 = -2
|
|
]
|
|
```
|
|
|
|
All results must match Lean `#eval` witnesses to pass.
|
|
|
|
## Action Items
|
|
|
|
1. **Python** — Write `tests/test_avm_python.py` with Lean-cross-validated test vector
|
|
2. **Coq** — Write `coq/AVMIsa/test_avm.v` with `Example` witnesses
|
|
3. **Scala** — Write test harness in `scala/src/test/`
|
|
4. **Go** — Write `go/avm_test.go`
|
|
5. **C** — Write `c/test_avm.c`
|
|
6. **C++** — Write `cpp/test_avm.cpp`
|
|
7. **Fortran** — Write `fortran/test_avm.f90`
|
|
8. **Octave** — Write `octave/test_avm.m`
|
|
9. **CI** — Add a GitHub Actions workflow that runs all port tests on every push
|
|
10. **Wolfram Alpha** — Re-audit all ports against the Lean reference
|
|
|
|
## Definition of Done
|
|
|
|
- [ ] All 12 ports pass the same cross-validated test vector
|
|
- [ ] Test outputs match Lean `#eval` witnesses for every operation
|
|
- [ ] CI pipeline runs all port tests on push
|
|
- [ ] Audit report (`docs/avm_ports_audit.md`) updated with "1:1" status
