Add sandbox_skip_permission_flags class attr and sandbox_binds() method to HarnessConfigurator ABC; thread sandboxed: bool = False through all build_spawn_config / build_resume_config signatures. Claude and Codex append their respective skip-permission flags when sandboxed=True; Kiro and Generic accept the param but add no flags. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
