It tries the normal provider path first and falls back to the minimal `jsonfrag` version (while-form) when needed, so you can inspect both the structural skeleton and the full lowering. - Current baseline observations (LLVM/EXE, `NYASH_SKIP_TOML_ENV=1 NYASH_DISABLE_PLUGINS=1`): `call`, `stringchain`, and `kilo` already beat the C reference (ratio < 100%), while `branch`, `arraymap`, and `chip8` remain near ≈200%—they are targets for the upcoming hoisting/array-map hot-path work. +### MIR emit stabilization (2025-11-13) + +The `--exe` mode now uses a robust Python3-based JSON extraction in `tools/hakorune_emit_mir.sh` to handle stdout noise from Stage-B.
