IDENTIFIED GAPS IN PIPELINE

1. Missing Audio Processing Layer (CRITICAL)

undefined

2. Missing Buffer Inspection (HIGH)

undefined

3. Missing Encoder Control Methods (HIGH)

4. Missing Network Transmission Hooks (MEDIUM-HIGH)

undefined

5. Missing Permission/Session Initialization (MEDIUM)

SPECIFIC METHODS TO ADD

Priority 1 (Complete the encoding chain):

FBSpeechHelperEncodingOpusConverter.encodeAudio:sampleRate:channels:quality:
FBSpeechHelperEncodingStrategy.selectEncodingFormat:
FBCCAudioDataPipe.processAudioBuffer:

Priority 2 (Monitor transmission):

FBSpeechHelperH2ServerSocket.sendData:length:
FBSpeechHelperSocket.writeData:length:

Priority 3 (Permissions verification):

FBMicrophonePermissionsManager.recordingPermissionGranted
AVAudioSession.recordPermission

CONCLUSION

Current capture demonstrates **activation & lifecycle** but **misses the transformation & egress** - critical for proving audio leaves the device in identifiable form.
