Codex rollout token budgets abort turns on exhaustion — a hard spend cap at the accounting boundary

What this changes for operators

• CLI 0.142.0 makes configurable rollout token budgets track usage across agent threads and abort turns when exhausted — a hard spend cap, not a warning. It is soft in timing: it lands at the next usage-accounting boundary with no cross-thread interrupt fan-out, so an in-flight expensive call can still complete.
• Set a rollout token budget and watch it abort a long multi-turn run at the accounting boundary; do not assume an instantaneous mid-response kill. Behavior under real multi-agent load is undocumented.
