Fix: Use Accessory activation policy — GUI shows without stealing focus from Ableton

Fix: Add hidePluginGui() implementation

Fix: Add hidePluginGui() method to Processor

Fix: GUI button toggles between Open GUI / Close GUI — sends hide_gui IPC command

Fix: GUI button toggles Open/Close — sends hide_gui when GUI is open, guaranteed to work"

Fix GUI close: Use JUCE custom title bar (not native) + force app activation via ObjC runtime

Fix: Make helper foreground process when showing GUI so window buttons work on macOS

Fix: Plugin GUI X button now closes window — custom DocumentWindow with closeButtonPressed override

Update SYNC.md — build passes, awaiting Ableton test

Fix: Add juce_events include to HelperConnection.h (Timer lives there) + add juce_events to CMake Plugin target

Fix: Replace removed juce::Thread::setCurrentThreadPriority with native pthread priority (macOS)

Fix: Editor reload button uses getLastPluginPath() (retained after crash)

Fix: Add getLastPluginPath() so reload works after crash, fix Editor reload button

Fix: HelperPluginHost.h use flat include for SharedAudioBuffer.h

Fix: HelperPluginHost.cpp use flat include for Constants.h

Fix: Helper/main.cpp use flat includes (Source/Shared in include dirs)

Fix: PluginBridgeProcessor.cpp use flat include for IPCProtocol.h (Source/Shared in include dirs)

Fix: Update HelperConnection.h include paths to use flat includes (Source/Shared is in include dirs)

Fix: Remove MSG_NOSIGNAL from HelperIPC.cpp, fix include paths for macOS

Fix: Replace MSG_NOSIGNAL (Linux-only) with macOS-compatible send() in HelperConnection.cpp and HelperIPC.cpp

Update SYNC.md — out-of-process rebuild pushed, ready for build test

Cleanup: Remove old in-process Source/ files (replaced by Source/Plugin/ and Source/Helper/)

Out-of-process rebuild: Add Plugin/McpServer.cpp — MCP tools route through helper IPC

Out-of-process rebuild: Add Plugin/McpServer.h/.cpp — routes MCP tools through HelperConnection

Out-of-process rebuild: New CMakeLists.txt — builds Plugin + Helper, bundles helper inside .vst3

Out-of-process rebuild: Add Plugin/PluginBridgeEditor.cpp — clean modern dark UI with status indicators

Out-of-process rebuild: Add Plugin/PluginBridgeEditor.h/.cpp — modern minimal dark UI

Out-of-process rebuild: Add Plugin/PluginBridgeProcessor.cpp — routes audio through shared memory to helper

Out-of-process rebuild: Add Plugin/PluginBridgeProcessor.h/.cpp — uses HelperConnection for crash-safe hosting

Out-of-process rebuild: Add Plugin/HelperConnection.cpp — full implementation

Out-of-process rebuild: Add Plugin/HelperConnection.h/.cpp — spawns helper, IPC, crash detection

Out-of-process rebuild: Add Helper/HelperIPC.cpp — handles commands from parent via Unix socket

Out-of-process rebuild: Add Helper/HelperIPC.h/.cpp — Unix socket IPC listener

Out-of-process rebuild: Add Helper/HelperPluginHost.cpp — full implementation

Out-of-process rebuild: Add Helper/HelperPluginHost.h/.cpp — loads plugin, runs processBlock, shows GUI

Out-of-process rebuild: Add Helper/main.cpp — standalone helper process entry point

Out-of-process rebuild: Add Shared/Constants.h

Out-of-process rebuild: Add Shared/IPCProtocol.h — message definitions for parent↔helper IPC

Out-of-process rebuild: Add Shared/SharedAudioBuffer.h — lock-free shared memory audio transport

Fix crash: Add validatePluginFile and lastError to header

Fix crash: Out-of-process plugin validation — test plugin in subprocess before loading in-process

Fix crash on load: Add try/catch around findAllTypesForFile + createPluginInstance, use async path

Fix: const auto& for file reference in showPluginMenu loop

Fix crash: Editor shows instant file-based popup menu — zero binary loading until select

Fix crash: Editor uses file listing, no scan — instant popup menu from filenames

Fix crash: Processor just lists files from disk — no scan, no binary loading

Fix crash: No plugin scanning — just list .vst3/.component files from disk, load on select

Fix crash: Update header — Timer-based scan, no background thread

Fix crash: Scan plugins on message thread via Timer (one per tick), not background thread"

Fix crash: Editor is thin — no threads, no scan ownership, just reads Processor state
