 ## Status
-**Last push:** 2026-05-16 — MAJOR REBUILD: Out-of-process plugin hosting
-**What's new:** Complete rewrite — plugin now runs in separate helper process (crash-safe). Two build targets: PluginBridge.vst3 + PluginBridgeHelper executable.
-**File structure changed:** Old Source/*.cpp files deleted. New structure: Source/Plugin/, Source/Helper/, Source/Shared/
-**Action needed:** MUST rm -rf build and reconfigure (cmake ..) before building
+**Last push:** 2026-05-16 — Out-of-process rebuild BUILDS SUCCESSFULLY ✅
+**Architecture:** Plugin runs in separate helper process. Crash-safe.
+**Action needed:** Test in Ableton:
+1. Load PluginBridge on a track
+2. Click "Select Plugin" → Pro-Q 4
+3. Click "Open GUI" → should open Pro-Q 4 in floating window
+4. Try Kickstart 2 → should NOT crash Ableton (helper crashes instead, shows reload button)
+5. curl -s http://localhost:16620/health
