Notes Notes
- The script uses Stage‑B entry (lang/src/compiler/entry/compiler_stageb.hako). - Stage‑B emit uses either the Stage‑B entry or BuildBox（HAKO_USE_BUILDBOX=1 for emit-only）
- Runner executes Core‑Direct in-proc under HAKO_CORE_DIRECT_INPROC=1. - Runner executes Core‑Direct in-proc under HAKO_CORE_DIRECT_INPROC=1.
- For heavier cases (bundles/alias/require), keep Stage‑B canaries opt‑in in quick profile. - For heavier cases (bundles/alias/require), keep Stage‑B canaries opt‑in in quick profile.
