nyash-codex 484bea946d VM: PHI strict default-ON + loop-header PHI fix; add VM step budget; StringBox.lastIndexOf; docs + strict smoke
- PHI strict: default ON, disable via HAKO_VM_PHI_STRICT=0 (alias NYASH_VM_PHI_STRICT=0)
- LoopForm: insert initial header PHI (preheader input) and rebind vars before condition; seal updates PHI inputs; avoid duplicate PHIs by replace
- MIR interpreter: add HAKO_VM_MAX_STEPS (alias NYASH_VM_MAX_STEPS) fail-fast budget to prevent infinite loops
- StringBox.lastIndexOf implemented (rfind, returns -1 when not found) in VM handlers
- Smokes: add strict/core/vm_phi_strict_smoke.sh (opt-in); quick remains green 120/120
- Docs: lang/src/vm/README.md and CURRENT_TASK.md updated with PHI strict policy and step budget

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)

  • Build: lang/build/build_runner.sh → produces lang/bin/hakorune
  • Requirements: LLVM 18 dev (llvm-config-18)
  • Run: lang/bin/hakorune

Notes

  • The launcher is minimal and prints a stable line [lang-launcher] hello.
  • This binary is a stepping stone towards a full selfhosted CLI built from Hakorune scripts.
