Codex shipped critical fixes for Guardian review configuration and SQLite projection recovery, ensuring conversation history stays consistent even when materializations fail.

The big move: Codex aligned Guardian reviews with session configuration [1], letting the review model use its own tool mode instead of Guardian-specific overrides, while refining policy precedence and prompt injection handling. Simultaneously, the team fixed a durability bug where SQLite projection failures would skip unprojected history suffix instead of catching up [2], ensuring thread history JSONL remains the durable source of truth. On the migration front, Codex prepared external agent transitions for source adapters [3], adding optional source selectors to agent detection while moving source-specific behavior behind adapter boundaries. The Node SDK addressed streaming reliability with three precision fixes: Zod v4 mini schema support for structured outputs [6], tool result message recovery in readable stream round trips [7], and a new fromReadableStream method for ResponseStream [8]. The Node team also shipped context passing to runTools callbacks [9], letting callers share typed context across tool execution without closures, and fixed Jest parallelization issues in Steady-backed test runs [10]. Model fallback handling got broader coverage [4] when resumed conversations hit unavailable models, and Guardian auto-review now respects model catalog policies [5] with proper precedence ordering.

Action items

→ Deploy Codex durability fix immediately if running resumed conversations with SQLite projections openai/codex [immediate]
→ Update openai-node to capture tool result messages in streaming runTools round trips openai/openai-node [plan]
→ Review Guardian policy precedence in your session configurations post-deployment openai/codex [monitor]
