harness-loop

The §5 autonomous-improvement-loop procedure specialized to this harness's own reviewer prompts (agents/code-reviewer.md + agents/security-reviewer.md) — the mission-specific 9-step regulation layered on skills/loop's generic mechanics. NOT for an arbitrary mission (use /loop for that), and NOT for editing core/tests/, evals/, or the guards themselves — that is the grader's own surface and is off-limits to any candidate this loop produces.
