Module agent_resume 

Durable interactive-agent session records, so a coding-agent TUI piloted through winx (claude, codex, …) is not silently lost when the process that owned its PTY dies (host reboot, guardian kill, embedded-adapter restart).

Modeled on herdr’s agent_resume (https://github.com/herdrdev/herdr, Apache-2.0): persist what was launched where, and rebuild a resume command after the loss. winx keeps it deliberately simpler than herdr — it records the launch command it executed itself instead of inspecting process trees, and resumes by conversation-continuation flags (claude --continue, codex resume --last) instead of persisted session ids.

Lifecycle: every foreground Command action either overwrites the record (the command launches a known agent) or clears it (it doesn’t) — the main PTY runs one foreground program at a time, so the latest record is the only one that can still matter. Records survive until superseded; a stale record after a clean agent exit only makes the recovery hint say the agent “was running”, which continuation-style resume commands tolerate.
