nyash-codex 6bfaaaf445 debug(mir): add comprehensive receiver tracing and block overwrite protection
This commit investigates ValueId(21) undefined error in Stage-B compilation.

Changes:
- src/mir/builder/builder_calls.rs:
  - Add NYASH_DEBUG_PARAM_RECEIVER=1 trace for method call receivers
  - Track variable_map lookups and ValueId mismatches
  - Log receiver origin and current_block context

- src/mir/builder/utils.rs:
  - Fix start_new_block() to avoid overwriting existing blocks
  - Check if block exists before calling add_block()
  - Prevents Copy instructions from being lost

- src/mir/function.rs:
  - Add warning log when replacing existing block
  - Helps detect block overwrite issues

- lang/src/mir/builder/ (Hako files):
  - Add debug prints for method lowering paths
  - These were not used (Stage-B uses Rust MIR Builder)
  - Kept for future Hako MIR Builder debugging

Key Discovery:
- Stage-B compilation uses Rust MIR Builder, not Hako MIR Builder
- ValueId(21) is undefined receiver in StageBArgsBox.resolve_src/1
- MIR shows: call_method ParserBox.length() [recv: %21] but %21 has no definition
- Likely caused by LocalSSA Copy emission failure or block overwrite

Next: Fix LocalSSA to ensure receiver Copy is properly emitted and preserved

Hakorune Lang Line — Rust-less Kernel (C ABI)

Scope

  • This lang/ tree hosts the script-driven C ABI kernel artifacts for Phase 20.9+.
  • Goal: keep the runtime data plane callable without Rust on the hot path (Hakorune → LLVM → C ABI).

Principles

  • Separation: do not mix Rust crates or cargo-specific layout under this tree.
  • Ownership & ABI:
    • Any char* returned across the ABI is owned by the callee and must be freed via hako_mem_free().
    • Do not mix CRT free() across boundaries.
  • FailFast: no silent fallbacks. Missing symbols must be observable via short diagnostics.

Layout (initial)

  • c-abi/ — C shim(s) and headers for the minimal kernel surface
    • README.md — responsibilities, build notes, platform caveats
    • include/ — public headers (mirrored or thin wrappers)
    • shims/ — libc-backed shim(s) for canaries and local testing

Build & Link (dev)

  • C shim: build a shared library to satisfy symbols for the LLVM line canaries.
  • Link flags example:
    • Linux: -L$(pwd)/target/release -Wl,-rpath,$(pwd)/target/release -lhako_kernel_shim

NonGoals

  • Plugin loader, HostBridge router, Box/Type system — kept in Rust.

Selfhost Launcher (AOT)

Dev line (Stage1 core experimental)

  • Dev build: tools/selfhost/build_stage1.sh → produces target/selfhost/hakorune
  • Role:
    • Fast iteration用の Stage1 selfhost バイナリNy Executor / CLI 実験など)。
    • new CLI/runner 機能はまずこちらで開発・検証する。

Stable line (lang bin snapshot)

  • Stable binary: lang/bin/hakorune
  • Build (pure-lang launcher, legacy bring-up):
    • lang/build/build_runner.sh → produces lang/bin/hakorune
    • Requirements: LLVM 18 dev (llvm-config-18)
  • PolicyPhase 25.1 以降の想定):
    • target/selfhost/hakorune で十分に安定したら、その成果物を lang/bin/hakorune に昇格させる(手動コピー or 専用スクリプト)。
    • lang/bin/hakorune は「last known good」の Stage1 コア EXE として扱い、配布や外部からの参照時は原則こちらを基準にする。

Notes

  • lang/ 以下は「最終的に 1 つの Stage1 コア EXEhakoruneを構成するソース群」という前提で整理する。
  • target/selfhost/hakorune は開発中の最新版、lang/bin/hakorune は安定版スナップショットという役割分担にする。
