Codex 0.143 remains alpha-only
The Codex 0.143 line stayed alpha-only through rust-v0.143.0-alpha.34 in this
window. Alpha changes include WebSocket liveness bounds, multi-agent/tool timing
telemetry, TTFT telemetry, and a quick-xml advisory fix. Channel:
preview-or-beta. Operator consequence: the runtime/observability work is real, but
there is no stable 0.143 tag to upgrade to.
