Port Cleanup

# Port Cleanup

**A Jev-powered native macOS utility for evidence-backed, human-confirmed cleanup of stale listening ports.**

Port Cleanup tells you which listening ports are safe to stop — and which are not — before anything is touched. Every TCP listener gets a typed recommendation from Jev, the evidence behind it, and an explicit decision that only you can make. No process is ever stopped automatically.



## Product view

The main window is where the decision happens: every listening port appears as a row with its executable, project context, Jev verdict, and confidence — and stopping anything still requires selecting the row and confirming.



## Why Jev matters

The hard part of port cleanup is not listing ports. It is deciding, per process, whether stopping it is safe — which usually requires understanding what that process actually is: a dev server you started an hour ago, a browser harness from a closed session, or something your system genuinely depends on.

**Jev** is the judgment engine behind Port Cleanup. It is a System One model from **TypeSafe** that turns each process's locally collected dossier into a typed judgment — a finite verdict/reason pair plus confidence and the single most material missing fact when the evidence is incomplete. Instead of asking a general-purpose model to freeform an answer, Port Cleanup asks Jev one finite-choice question per process: is this safe to stop, keep, or your decision? The result is a validated, typed response the app can map to its own text, not raw model prose you have to trust.

That is the central differentiator: **local forensic evidence plus typed AI judgment, gated by explicit human confirmation.** The app collects everything it can prove on your Mac, Jev classifies what it sees, and you — not the model, not
