Internal package of Claudexor — Codex CLI adapter over the native app-server JSON-RPC lifecycle.

One app-server child owns one Claudexor run. Native goal continuations and run-owned background terminals keep that run active; Stop pauses the goal, interrupts the exact active turn, and terminates only terminals observed in that run.

The verified install pin is codex-cli 0.162.1. Its selected-account model/list capture is fixtures/models-0.162.1.json; the fallback keeps historical model ladders but takes the captured default (gpt-6.1-sol) from that version. The native turn-text bound was re-probed against an unauthenticated loopback provider: 1,048,576 Unicode scalars accepted; 1,048,577 refused before a provider request. This is a character bound, not a model token-window guarantee.

Live messages (POST /v2/runs/:id/messages, capability live_input: mid_turn): message(sessionId) steers the ACTIVE turn through turn/steer. Outcomes come from adapter state, never from error prose: accepted when the server answers {turnId}; delivered when the userMessage echo carrying our client id arrives (also yielded as a live_input_delivered status event); rejected when a refusal lands while the turn is still active; not_active when no turn is active (goal-continuation gap, background-terminal wait, after Stop); delivery_unknown on transport loss, a malformed reply or a missed 30 s deadline. A steer never fails or cancels the run. Recorded on codex-cli 0.156.1 in fixtures/app-server/recorded-steer-0.156.1.jsonl.

Published as part of the Claudexor toolchain; it follows the monorepo's lockstep version and has no separate semver contract. Use the claudexor CLI (or @claudexor/cli) as the supported entry point.
