# Codex Harness Team

Use this featured profile for general engineering when ChatGPT-backed Codex access is the only required service. Sol owns the critical path and all writes; Luna scouts and Terra designs invariants in isolated native contexts; a fresh Sol context performs one mechanically supervised post-diff review.

The profile demonstrates that context isolation, parallel read work, role specialization, and adversarial review can add value without changing model makers. Native controls remain advisory, so both native workers are read-only. If the fresh MCP critic cannot run, the root continues with visibly reduced independent verification.

The fresh critic is the one supervised persistent app-server worker: the integrator can inspect, steer, interrupt, continue, finalize, fork, or cancel it, and its trace and partial evidence survive host loss. Luna and Terra remain native Codex participants; they intentionally demonstrate native context isolation and are not presented as mechanically app-server-controlled workers.
