Autonomous health maintenance: Gaius escalates over ACP for code-level remediation.

Gaius closes the inner loop on self-remediation. The HealthObserver daemon — running alongside the engine — watches for incidents that the /health fix path cannot resolve at runtime. When one appears, it escalates over the Agent Client Protocol to a coding agent with the Gaius MCP server attached. The agent opens a GitHub issue, implements a FixStrategy, and registers a heuristic in the knowledge base.

The autonomy is real — agents reading their own failure surface and proposing code-level repairs against the framework that hosts them — but it is bounded. All changes land on a review branch. Issue creation is rate-limited to three per twenty-four hours. The rate limit is a circuit-breaker, not a comment.

A self-improving agent that earns the name is one whose improvements can be reviewed.
