Activity Monitor

Activity Monitor is a first-party Matrix OS app for inspecting the current Matrix computer. It shows the machine identity, installed release, uptime, CPU pressure, memory, disk usage, service health, top processes, and safe cleanup suggestions from the gateway running on that computer.

Cleanup actions are typed and server-issued. The shell can only submit an opaque cleanup candidate and confirmation token returned by the gateway; it cannot send arbitrary PIDs or filesystem paths. The gateway revalidates the target before any mutation and records cleanup history in the owner's Matrix home.

Automatic cleanup remains opt-in. In v1, automation is limited to conservative high-confidence stale app servers, approved cache scopes, and inactive non-rollback bundles. Terminal sessions and code-server restarts stay manual-only.
