Summary
codex-app-servertargets now drive the installed Codex app-server as the interactive JSON-RPC endpoint it is, instead of sending a one-shot custom payload and waiting forcodex exec --json-style output. The adapter initializes the app-server, starts an ephemeral thread, starts a turn with the AgentV prompt, and extracts the final assistant message from app-server notifications beforeturn/completed.The failure mode from the prior live matrix was a protocol mismatch: Codex 0.142.5 rejected AgentV's
{ type: "agentv.invoke" }stdin object with a JSON-RPC deserialization error, so AgentV reported malformed/no output. This PR keepscodex-clibehavior unchanged and scopes the interactive protocol path toprovider: codex-app-server.Related: EntityProcess/agentv-beads#20
