The replacement for general-purpose coding harnesses. Operator with socket and pipe I/O, fully customizable run-loop, tool surface, subagent taxonomy, and cognitive prompt (purpose / ego / fear). Systemd-supervised. Standard JSONL session format. Best-in-class steering and observability — debuggable, in-house, ours.
