+## Launch prompt
+
+```
+Start F1 of the SDLC pipeline refactor — handbook reconciliation in
+wiggleverse/engineering (issue #63 on the dev-claude-plugin tracker): §3.3
+accretion, §4.3 slice-retirement (Feature = one SPEC = one plan = one execution;
+Stories become standalone leaf issues, R2(b)), solution-design GUIDE/TEMPLATE
+updates, and the documented home of the Claude-Design-vs-Code decision.
+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._
