+## Launch prompt
+
+```
+Capture a Feature on the tracker: extend the authoring flow (F2/F3/F4 — threads /
+attribution / Ask Claude to Edit Selection) to files OUTSIDE the workspace folder,
+persisting the sidecar in VS Code global storage keyed by URI hash (like F6's
+baseline) for out-of-workspace/untitled files. Recommended hybrid model: in-workspace
+files keep the committable .threads/ git-native sidecar (INV-2 unchanged); only
+out-of-workspace/untitled files fall back to global storage. Note F5 cross-rung
+interaction. Origin: F7 manual testing (sessions 0021/0022); operator chose global
+storage.
+
+```
+
+## 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._
