 - Settings object: `UCLASS(config=Engine, defaultconfig)` inheriting `UObject`, registered via `ISettingsModule`
 - Module startup: `NewObject<USettings>(..., RF_Standalone)` + `AddToRoot()`
 - WebSocket: `FWebSocketsModule::Get().CreateWebSocket(URL, TEXT(""), Headers)`
-- Audio capture: `Audio::FAudioCapture` from the `AudioCapture` module
+  - `WebSockets` is a **module** (Build.cs only) — NOT a plugin, don't put it in `.uplugin`
+- Audio capture: `Audio::FAudioCapture::OpenAudioCaptureStream()` (UE 5.3+, replaces deprecated `OpenCaptureStream`)
+  - `AudioCapture` IS a plugin — declare it in `.uplugin` Plugins array
+  - Callback type: `FOnAudioCaptureFunction` = `TFunction<void(const void*, int32, int32, int32, double, bool)>`
+  - Cast `const void*` to `const float*` inside — device sends float32 interleaved
 - Procedural audio playback: `USoundWaveProcedural` + `OnSoundWaveProceduralUnderflow` delegate
 - Audio capture callbacks arrive on a **background thread** — always marshal to game thread with `AsyncTask(ENamedThreads::GameThread, ...)`
 - Resample mic audio to **16000 Hz mono** before sending to ElevenLabs
+- `TArray::RemoveAt(idx, count, EAllowShrinking::No)` — bool overload deprecated in UE 5.5

+- **PS_AI_Agent_ElevenLabs**: compiles cleanly on UE 5.5 Win64 (verified 2026-02-19)
