# Phase 20.26 — Checklist

Status legend: [ ] pending, [~] in-progress, [x] done

Phase A — Deprecation + Docs (safe, no behavior change)
- [x] Deprecate banner when `llvm-inkwell-legacy` path executes (runner/modes/llvm)
- [ ] One-time compile-time banner when feature is built (optional)
- [x] Docs scaffold (README/PLAN/CHECKLIST) present
- [x] CURRENT_TASK updated to Phase 20.26 focus

Phase B — Archive + Feature Gates
- [x] Move `src/backend/llvm/compiler/**` → `archive/legacy/llvm-inkwell/**`
- [x] Keep feature wiring via shim (build stays green; feature off by default)
- [x] Add opt-in smoke to assert deprecate banner

Phase C — Runner Plan (opt-in)
- [x] Add lang `RunnerPlanBuilder` skeleton (decision only)
- [x] Add thin adapter in Rust runner (apply plan)
- [x] Toggle `HAKO_RUNNER_PLAN=1` guarded; defaults unchanged
  - v0: action ExecuteCore/ExecuteVM を適用（Gate‑C/VM）。既定不変。

Phase D — hakmem (gate only)
- [x] CLI `--mem {libc|hakmem}` to ENV (`HAKO_C_ABI_ALLOC`)
- [x] Keep default libc; docs updated; no behavior change（introspection: `hako_allocator_name()` 追加）

Status (2025-10-30)
- quick: PASS 56 / SKIP 16 / FAIL 0
- integration-core: PASS 26 / SKIP 0 / FAIL 0
- Gate‑C/Core: Early routing (JSON→Interpreter) in place; no boot-plan/ny-compiler noise.

Docs/Comms
- [x] env-variables: reference `--vm-backend`, `HAKO_LLVM_USE_HARNESS`, `HAKO_C_ABI_ALLOC`
- [ ] migration notes: prefer harness; inkwell legacy; rollback path

Tests/Smokes
- [ ] quick stays green (default). No noise banners unless path used.
- [ ] opt-in smoke: inkwell banner visible when feature path chosen
