+// ext-stage-dock glue (b4 SKELETON). The decision cores live in src/reveal.hpp
+// (the reversible edge-swipe recognizer) and src/dock_layout.hpp (reveal ->
+// on-screen geometry) — both wlroots/GL/RMLUi-free and doctest-hard. THIS file
+// is the thin effectful edge: for now it is a deliberate no-op that just logs at
+// activate(), so the unit compiles and installs cleanly while the real wiring
+// (c2 static integration, d1 animation, e1 gesture) lands in later steps.
+//
+// Everything runs on the single wl_event_loop thread. Every future resource will
+// be a RAII member of StageDockExtension; teardown is reverse-declaration
+// destruction (no manual teardown lists — extension-agent.md).
