Remove legacy hardcoded 'sum' carrier validation that was blocking array_filter patterns with different accumulator names (e.g., 'out'). Before: Pattern3 required carrier named 'sum' to exist After: Pattern3 uses carrier_info generically (any carrier name works) Test results: - phase49_joinir_array_filter_smoke: PASS ✅ - phase49_joinir_array_filter_fallback: PASS ✅ - phase49_joinir_array_filter_ab_comparison: PASS ✅ - Full suite: 909/909 PASS, 0 FAIL Also: Archive old roadmap documentation (67k lines moved to docs/archive/) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Phase 21.6 — Dual‑Emit Parity & C‑line Readiness
|
||
|
||
Goal: Produce identical MIR(JSON) from both provider (Rust) and selfhost (Hako) builder paths, measure generation cost, and keep AOT (ny‑llvmc) fast/green. All work is semantics‑preserving; defaults remain unchanged.
|
||
|
||
## Checklists
|
||
|
||
- [ ] Dual‑emit parity on representative apps (MIR(JSON) normalized SHA1 equal)
|
||
- [ ] Resolver‑first ON passes quick/integration
|
||
- [ ] Selfhost‑first fallback ok (provider/legacy on failure)
|
||
- [ ] AOT obj/exe via ny‑llvmc (crate backend) green
|
||
- [ ] Docs updated (bench guides, env vars, quick recipes)
|
||
|
||
## Scripts
|
||
|
||
- Dual emit + compare + bench: `tools/perf/dual_emit_compare.sh <input.hako> [rounds]`
|
||
- MIR emit bench: `tools/perf/bench_hakorune_emit_mir.sh <input.hako> [rounds]`
|
||
- AOT bench: `tools/perf/bench_ny_mir_builder.sh <mir.json> [rounds]`
|
||
- MIR diff: `tools/perf/compare_mir_json.sh <a.json> <b.json>`
|
||
|
||
## Env Knobs
|
||
|
||
- `HAKO_USING_RESOLVER_FIRST=1` (resolver‑first)
|
||
- `HAKO_SELFHOST_BUILDER_FIRST=1` (selfhost→provider→legacy)
|
||
- `HAKO_MIR_BUILDER_BOX=hako.mir.builder|min`
|
||
- `NYASH_LLVM_BACKEND=crate`（ny‑llvmc）
|
||
- `HAKO_LLVM_OPT_LEVEL=0|1`（AOT O0 既定）
|
||
|
||
## Benchmarks — Tracking
|
||
|
||
Record normalized parity and generation times here (edit in place).
|
||
|
||
Legend: SHA1 = normalized JSON digest; Parity=Yes when SHA1 equal; Times are medians unless noted.
|
||
|
||
| Benchmark (Hako) | Resolver | Parity | Provider p50 (ms) | Selfhost p50 (ms) | Notes |
|
||
|------------------------------------------|----------|--------|-------------------|-------------------|-------|
|
||
| apps/examples/json_query/main.hako | off/on | | | | |
|
||
| apps/examples/json_pp/main.hako | off/on | | | | |
|
||
| apps/examples/json_lint/main.hako | off/on | | | | |
|
||
| apps/examples/json_query_min/main.hako | off/on | | | | |
|
||
|
||
How to fill:
|
||
1) Run `tools/perf/dual_emit_compare.sh <file> 5`
|
||
2) Copy p50s from the summary lines and mark Parity based on `compare_mir_json.sh` output.
|
||
3) Note any diffs (callee kinds/order/phi/meta) in Notes.
|
||
|
||
## Next Steps
|
||
|
||
- [ ] If parity holds on the above set, extend to apps/tests subset
|
||
- [ ] If diffs remain, categorize and align either provider or selfhost output
|
||
- [ ] Keep AOT line green under `HAKO_LLVM_OPT_LEVEL=0` and optional `=1` spot checks
