NEVER Do (Expert Anti-Patterns)

Audio Sync & Logic

• NEVER use Time.get_ticks_msec() for rhythm sync; strictly use AudioServer.get_time_since_last_mix() combined with latency offsets for sub-frame accuracy.
• NEVER process song logic in _process(); strictly use _physics_process() or a conductor loop to ensure deterministic timing regardless of render frames.
• NEVER use _process() to capture hit inputs; strictly use _input(event) to record the exact timestamp of the button press event.
• NEVER scale engine time_scale for song speed; strictly use AudioStreamPlayer.pitch_scale to adjust speed and avoid globally breaking physics logic.
• NEVER ignore Audio Latency Calibration; strictly provide a manual offset menu to compensate for varied hardware (Bluetooth vs Wired).
• NEVER use yield or await for beat timing; strictly use a sample-accurate Delta Accumulator tied to the audio clock.
• NEVER assume a constant BPM; strictly build your conductor to handle a Tempo Map for complex track changes.
