The rules file (`rules/argent.md`) and the MCP server instructions both tell every session to call it at session end. On a machine running several concurrent agent sessions against the one shared tool-server, one session ending severs the transports of all the others mid-work.

This is a regression: it works in `0.11.0` and breaks in `0.12.1`. ## Environment - argent `0.12.1` (broken) vs `0.11.0` (works) - macOS 26.x, Apple Silicon - Xcode iOS Simulators (iOS 26.x) ## Repro 1.

It re-parents to launchd (ppid 1) and runs indefinitely. There appears to be no parent-death detection (stdin EOF / ppid watchdog) and no idle timeout. ## Repro (verified) 1.

I [looked through the Claude Code docs](https://code.claude.com/docs/en/mcp) and didn't see any mention of a "servers" key.
