+## Launch prompt
+
+```
+/goal wgl-capture SLICE-1 — tracked-lite capture session plumbing (--type capture in claim, a capture branch in finalize, the 5th gate type), per the spec §7.2 + Feature #25's checklist.
+
+The Patchwatch rfc-app remediation goal stays parked (blocked on a depth call).
+
+```
+
+## 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._
