Source: engineering docs/sdl-pipeline-refactor-brief.md (decisions locked). It's the docs-lead spine F2–F5 cite — first. ``` ## Deferred decisions _Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Appended as the session runs; surfaced at finalize. Empty if none._
