# De‑Rust Gap Analysis (Phase 21.9)
|
||
|
||
This memo enumerates gaps to execute Phase‑1/2 tasks safely.
|
||
|
||
## hv1_inline → Parity
|
||
- JSON support: ensure compare/branch/jump/phi/mir_call minimal are covered.
|
||
- Parity canaries: phase2037/* (flow), phase2170/* (state).
|
||
- Env guard: consider `HAKO_VERIFY_DISABLE_INLINE=1` for hard opt‑out (optional).
|
||
|
||
## TLV Codec → C shim
|
||
- Minimal C API: tlv_encode(buf,len, out_ptr, out_len) / tlv_decode(...)
|
||
- FFI wrapper in Rust; map errors to Result.
|
||
- Tests: round‑trip on byte arrays; malformed inputs; size limits.
|
||
|
||
## MIR Interpreter (Rust) — Diagnostic mode
|
||
- Keep as fallback/diagnostic; Primary = Hakovm.
|
||
- Ensure boxcall/mir_call minimal parity for sample set.
|
||
- Gate via env to avoid accidental use in primary flows.
|
||
|
||
## LLVM Wrapper → Hako/C Harness
|
||
- Keep Python llvmlite primary until Hako IR is mature.
|
||
- Hako wrapper CLI to drive harness with env (`NYASH_LLVM_USE_HARNESS=1`).
|
||
- Tests: small end‑to‑end const/ret and simple branch; IR dump gate remains.
|
||
|
||
## Resolver/Using SSOT (Hako First)
|
||
- Runner policy and HakoCheck strip/order unified; document precedence.
|
||
- Strict profiles disallow path‑literal using.
|
||
|
||
## FileBox Core → C (later)
|
||
- Small C layer for read‑only (Analyzer) and read/write (dev) under caps; Rust shim remains.
|
||
|
||
## Acceptance Summary
|
||
- Build: cargo build (default) green.
|
||
- Smokes: quick/core green; parity canaries pass.
|
||
- Docs: roadmap + plan page + restore steps present.
