CODEX REFACTORS THREAD ORDERING AND FILE STREAMING AS SDK RELEASES ROLL OUT

Codex shipped a server-owned recency timestamp to decouple sidebar ordering from mutation tracking [ref:1], while the Node and Python SDKs both landed point releases with fixes and new admin APIs [ref:6] [ref:11].

The Codex team is stabilizing core infrastructure ahead of larger refactors. A new `recencyAt` field [1] lets clients sort threads by recency without conflating it with `updatedAt`, the actual mutation timestamp. In parallel, path handling got clarified [2] to separate model-generated paths from legacy API paths, preventing the model from generating relative paths where absolute ones are required. On the runtime side, cell lifecycle behavior is now codified with expanded test coverage [3], locking in intended semantics before refactoring the runtime. File streaming also got the streaming treatment [4]: exec-server now chunks large remote reads into 1 MiB blocks with backpressure instead of buffering everything in memory. Across the SDKs, openai-node v6.43.0 [5] fixed TypeScript configuration and restored pnpm setup, while openai-python v2.42.0 [6] added admin spend_alerts API support and synced with the latest OpenAPI spec.
