The final file can peak differently from the session meter.
Export, sample-rate conversion, dithering, and encoding preparation can change the waveform enough to create a new true-peak reading.
A session that looked safe can still produce an exported file that clips after conversion or playback reconstruction.
Open the exported WAV or final delivery format and check integrated loudness, true peak, and any obvious overs from start to finish.
Do not assume the last plugin meter is the final answer. The rendered file is the delivery object.
Use a sensible limiter ceiling, avoid last-second normalization surprises, and leave enough true-peak margin for the format you are delivering.
Meter Core can be used as a final quality-control meter so the export matches the mix decision.
