- Use Codex usage config extraction to log the effective thinking effort
- Include baseline level in logged fields when the top-level mode is configured
- Guard config extraction and logging behind a debug log level check
- Handle unchanged native Responses payloads before user-defined model processing
- Extract and log original and processed thinking configuration when present
- Return payload unmodified without rewriting or re-validating
- Attach resolved execution model info during execution and token counting even when restoring execution models
- Propagate configuration update support to resolved Home dispatch model info
- Track modifications to configuration updates across plugin normalizers in the translation pipeline
- Mark configuration update support for eligible Codex models in the registry
- Inspect `input` items for the latest `configuration_update` reasoning effort before falling back to top-level configuration.
- Route `codex`, `xai`, and `openai-response` providers through usage-specific thinking config extraction.
- Support `none`, `auto`, and explicit reasoning level modes from in-turn updates.
