The path-dep also forced an +out-of-band checkout in CI (the agent-service test job was disabled by +default) and a Node build stage plus a named build context in every +Dockerfile that built agent-service. + +OpenAI has since shipped `openai-codex` (Beta). It *is* the harness, not +a thin wrapper: it spawns and drives `codex app-server`, exposes native +threads (`thread_start` / `thread_resume`), streams typed +`Notification{method, payload}` objects, supports `Sandbox.read_only`, +server-enforced `output_schema`, a per-thread `config` overlay (for +MCP-server and built-in-tool configuration), and a native `AsyncCodex` +with `async for event in turn.stream()`. The original reason the sister +package existed is gone. + +## Decision + +### 1. Drive codex through `openai-codex`, one shared app-server + +The codex runtime is one `AsyncCodex` built at FastAPI lifespan +(`main.py`), closed at shutdown, stored on `LoopHandles.codex`. The SDK +bundles the codex binary (`openai-codex-cli-bin`), so no separate CLI +install is needed; it reads subscription auth from `auth.json` under a +writable `CODEX_HOME` seeded from the read-only `~/.codex` mount. + +`codex_driver.run_turn_codex` keeps its public contract (`AgentRequest` +-> SSE frames) and its entire post-stream gate / claim-drain / span +machinery. Only the event *source* changed: instead of a sync driver +pumped over a worker thread + `asyncio.Queue`, it does +`thread.turn(...)` then `async for notification in handle.stream()`. +The SDK's typed payloads are dumped back to their camelCase wire dict +and parsed by `agent_service.codex_events` (a small self-owned parser +ported from the codex app-server protocol), so beta SDK +typed-attribute churn cannot ripple through the driver. + +### 2. Native threads replace per-thread `codex_home` + +Each chat thread maps to one native codex thread. `AgentThread` stores +the SDK `thread.id`; a new chat calls `thread_start`, a resume calls +`thread_resume(thread_id)`. This deletes the `CODEX_HOME_ROOT` +per-thread materialization, the `prepare_actor_codex_home` symlink +dance, and the `state_5.sqlite` model-name read hack (the effective +model is now the one we requested, stamped directly on the chat span). + +Trade-off accepted: chats now share one app-server process and one +sqlite (native thread isolation) instead of filesystem-level isolation. +For a single-developer service this is strictly simpler with no +observable behavior loss. + +### 3. Lockdown + MCP move to the per-thread `config` overlay + +The built-in-tool lockdown (disabling shell, unified_exec, apply_patch, +web_search, view_image, image_generation, computer_use, browser_use, +apps, tool_search) and the analyst MCP-server mount with its four-tool +allow-list are now a per-thread `config` dict passed to `thread_start` +/ `thread_resume` (`codex_config.py`), plus `Sandbox.read_only` and +`approval_policy = "never"`. The disable map is ported verbatim from the +old driver and keeps the codex-SHA pin comment. The `no-builtin-tool-call` +eval probe remains the regression net. + +### 4. Helper app-server stays separate + +The gates / eval judge / repeat detector run through a *second* +module-level `AsyncCodex` (`llm_runtime.py`) with its own `CODEX_HOME`, +ephemeral threads, the lockdown overlay, and no MCP server. This +preserves ADR 15 ยง3's no-bleed property (analyst MCP traffic never +reaches a helper call) using two app-servers instead of two session +pools. `to_strict_json_schema` + `_parse_strict` are unchanged; the +helper now calls `thread.run(prompt, output_schema=...)` and parses +`result.final_response`. + +## Consequences + +### Accepted +- The SDK is Beta. API-churn risk is recorded in + `docs/dependency-exceptions.md` with an exact version pin and a + revisit trigger; the `codex_events` parser contains the blast radius. +- Two codex app-server processes per service (analyst + helper) instead + of one driver with two session pools.
