# Goal: Windows Local Sing-Box Use Krypton Execution to execute `docs/goals/windows-local-singbox/PLAN.md`. Core rules: - Treat PLAN.md as the source plan. - Preserve intent, ownership, contract, cutover, evidence, and kill criteria. - Implement the feature as the existing optional Local sing-box component, not as a new unrelated component id. - Keep external proxy flow working without Local sing-box. - Do not add hidden installation during profile apply. - Do not import or call the root Node server from the Windows client. - Capture acceptance evidence from the target perspective and record it in EVIDENCE.md. - Say "implemented but unproven" if elevated Windows service evidence cannot be captured.
