+## Launch prompt
+
+```
+Brainstorm the Solution Design spec for Feature #12 (F4 — propose/accept diff flow: inline diff + keep/reject on the applyAgentEdit seam) on benstull/vscode-cowriting-plugin, resolving the five design forks routed there by the capture (proposals[] shape; rendering primitive; propose-by-default vs. direct mode; multi-range seam growth; accept/reject granularity), then graduate it to vscode-cowriting-plugin-content/specs/. (Continuation of /goal F4, session 0010 capture → this spec session.)

+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Appended as the session runs; surfaced at
