Five views, Tab between them: Overview (each core's load, memory, traffic, battery, two minutes of load), Tasks (share of a core over the last second, lowest free stack, flagged under 512 bytes; `s` sorts), Memory (free heap against the floors of Q86), Network (bytes per service, and what's moving now), System (what `info` prints, plus battery, card, radio, GNSS). It samples once a second and keeps history only while open. The arithmetic is host-tested, including the trap found on the device: a task's run-time counter only moves when it's switched out, so the task that samples (the main loop, alone on its core) gets what's left of its core. `tasks` now samples across a second of normal running instead of inside its own wait. The main loop uses 100 % of core 1 at rest (#40). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT
