+## Launch prompt
+
+```
+/goal F3 — wgl-tech-design (#127): new gate-lifter skill authoring the SPEC Engineering lens, accreting after brd/prd.
+Part of the staged-gate SDLC refactor (Epic #125). F1 (handbook accretion) and F2 (wgl-brainstorming --lenses brd|prd) shipped. F3 adds the Engineering-lens gate-lifter that accretes the engineering lens into the SAME SPEC after the business/product lenses.
+
+```
+
+## 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._
