# Phase 20.24 — Parser削除（Checklist）
|
|||
|
|
|
|||
|
|
Status: Phase A completed（gate wiring + canaries, opt‑in）
|
|||
|
|
|
|||
|
|
Scopes
|
|||
|
|
- Parser backend gate（CLI first, ENV alias）
|
|||
|
|
- Quick/integration parity canaries（opt‑in）
|
|||
|
|
- Default stays Rust until sustained green
|
|||
|
|
- Archive→Delete is Phase C
|
|||
|
|
|
|||
|
|
Phase A — Gate & Validation（完了）
|
|||
|
|
- [x] CLI `--parser=hako|rust` wired（env alias: `HAKO_PARSER_BACKEND`）
|
|||
|
|
- [x] Runner pipeline uses FlowEntry（Stage‑1→MIR v1+meta→v0）
|
|||
|
|
- [x] Quick parity canaries（return/if/binop）
|
|||
|
|
- [x] Quick allowlist opt‑in toggle（`SMOKES_ENABLE_PARSER_PARITY=1`）
|
|||
|
|
- [x] Integration parity canary（return, opt‑in）
|
|||
|
|
|
|||
|
|
Phase B — Observation & CI
|
|||
|
|
- [ ] CI job for parity (quick profile ×2 backends)
|
|||
|
|
- [ ] Periodic large‑source parity run（manual or nightly）
|
|||
|
|
- [x] Docs: troubleshooting + rollback（fallback環境 HAKO_PARSER_AUTO_FALLBACK=1）
|
|||
|
|
- [x] Integration parity canaries（return/if）
|
|||
|
|
- [x] Docs: env variables for parser backend (`HAKO_PARSER_BACKEND`, `HAKO_PARSER_AUTO_FALLBACK`) updated
|
|||
|
|
|
|||
|
|
Phase C — Default Flip & Removal（進行中）
|
|||
|
|
- [x] Default parser → hako（ENV/CLI keeps legacy opt‑in: `--parser-backend=rust`）
|
|||
|
|
- [ ] Archive `src/parser` and `src/ast`（tag + branch backup）
|
|||
|
|
- [ ] One release of observation, then delete
