Codex Switch JNSLayer2

Internal macOS menu bar app for secure multi-account switching.

v3 highlights

• Auto-switch when the active account drops below the configured remaining quota threshold.
• Global threshold plus per-account override support.
• Auto-repair desktop session/cache residue before deciding whether a stale low-quota state really requires switching.
• Transactional post-switch verification using codex login status plus a minimum codex exec smoke test.
• Batch relogin flow for stale accounts.
• Repair Codex desktop session/cache residue after plan upgrades so new Plus / Pro subscriptions are recognized.
• doctor CLI entrypoint for verify / repair / stale scan / autoswitch dry-run.
• Helper CLI as the single source of truth for app and agent automation.
