nyash-codex 804ccff23f feat(phase73): Selfhost Stage-B I/O 簡素化 - HAKO_SRC 環境変数統一化
Unified selfhost Stage-B I/O path from argv to environment variables:
- Remove --source "$SRC_CONTENT" from compiler.hako invocation (argv limit)
- Export HAKO_SRC="$SRC_CONTENT" instead (env-based I/O)
- Update compiler_stageb.hako to check HAKO_SRC fallback

Changes:
1. lang/src/compiler/entry/compiler_stageb.hako:
   - Added HAKO_SRC env check in StageBArgsBox.resolve_src()
   - Fallback order: --source arg → HAKO_SOURCE_FILE_CONTENT → HAKO_SRC → default

2. tools/selfhost/selfhost_build.sh:
   - Removed --source "$SRC_CONTENT" from compiler.hako invocation
   - Export HAKO_SRC="$SRC_CONTENT" before Stage-B execution
   - Unified with wrapper pathway (HAKO_USE_BUILDBOX=1)

Benefits:
- Eliminates "Argument list too long" (os error 7) for large .hako files
- Single unified I/O pattern (env variables) for all Stage-B paths
- Consistent with hako_check.sh and wrapper pattern
- Ready for future HAKO_SRC_FILE optimization

Verification:
 NYASH_FEATURES=stage3 NYASH_USE_NY_COMPILER=1 \
  ./tools/selfhost/selfhost_build.sh --in apps/tests/stage1_run_min.hako --run
  Output: abc (correct)

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。
