# Phase 20.9 — Structure (Lang Line)
|
|
|
|
Decision
|
|
- Introduce `lang/` at the repository root to host the C ABI kernel and related artifacts (no Rust here).
|
|
- Keep Rust engine/crates under `crates/` and `src/` untouched. The `lang` line is a separate box.
|
|
|
|
Layout
|
|
- `lang/` — top-level
|
|
- `c-abi/` — headers and libc-backed shim for canaries
|
|
- `README.md` — responsibilities and contracts
|
|
- `README.md` — scope and principles
|
|
|
|
Rationale
|
|
- Clear separation of concerns: script-driven ABI vs. Rust runtime internals.
|
|
- Makes it easy to package/link the C shim with external harnesses without dragging Rust sources.
|
|
|
|
Notes
|
|
- Migration is incremental: existing headers/shims remain in `include/` and `c/abi/` until references are updated.
|
|
- CI/docs should point to `lang/c-abi` once stabilized; older paths deprecated after a grace period.
