Quick Win 1: Show available boxes on "Unknown Box type" error - vm.rs, vm_fallback.rs: Display sorted list of available user-defined boxes - Before: "Unknown Box type: Foo" - After: "Unknown Box type: Foo. Available: Bar, Baz, Main" Quick Win 2: Show stderr on child process timeout - child.rs, selfhost_exe.rs: Capture and display stderr (up to 500 chars) - Helps diagnose what went wrong in selfhost compiler child process Quick Win 3: Simplify Stage-B compiler API (SSOT) - compiler_stageb.hako: Add StageBDriverBox.compile() as single entry point - compiler_stageb.hako: Remove StageBMain compatibility wrapper - compiler.hako: Change from `using ... as StageBMain` to direct import - compiler.hako: Call StageBDriverBox.compile() directly Also includes child_env.rs NYASH_MODULES env var for module mapping. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
