Codex analysis

[21stSentry]

Just out of curiosity I had Codex scan through the code. My coding is limited to basic PHP etc, but for what it's worth...
It might be interesting to see if Claude Opus has the same suggestions.

Major fixes

1. Worker socket bug: corrected wrong command socket validation (m_cmdOut vs m_cmdIn).
   Server/Source/Worker.cpp
2. Realtime timing safety: clamped workDurationMs to avoid underflow/invalid values.
   Plugin/Source/Client.cpp
   Server/Source/Worker.cpp
   Plugin/Source/AudioStreamer.hpp
3. Client connection robustness:

• fail-fast when command receive socket setup fails
• replaced raw new/delete audio socket with unique_ptr
• RAII lock in close path
  Plugin/Source/Client.cpp

4. Build portability fix: added missing include for chrono literals.
   Common/Source/Utils.hpp
5. ProcessorChain correctness:

• sidechain discrete bus used wrong channel count (channelsIn -> channelsSC)
• fallback layout channel count computation fixed
• failed plugin load no longer inserts processor into chain
  Server/Source/ProcessorChain.cpp

6. AudioStreamer hot-path optimization:

• replaced per-sample shift loop with memmove per channel in consume path
  Plugin/Source/AudioStreamer.hpp

7. ScreenWorker optimizations:

• runNative: heavy diff/encode now runs mostly outside m_currentImageLock
• runFFmpeg: swap/copy metadata under lock, send outside lock
• replaced one manual lock/unlock with RAII
  Server/Source/ScreenWorker.cpp

8. Async lifetime bug fixes in worker callbacks:

• avoided dangling reference captures across async boundary
• key forwarding now copies payload buffer safely instead of copying non-copyable Message
  Server/Source/Worker.cpp

Validation

1. Configured CMake build tree (build-check2) successfully.
2. Built plugin target successfully: AudioGridderFx.vcxproj.
3. Built server target successfully: AudioGridderServer.vcxproj -> AudioGridderServer.exe.
4. Synced all modified files into Audiogridder2 and verified mirrored files are identical.
