problem
The last processor determines what actually leaves the master chain.
A meter before the final limiter shows what enters the limiter, not the final ceiling, loudness, or true-peak behavior.
Limiter release, oversampling, output ceiling, and downstream processing can all change what the exported file will contain.
Place a meter after the limiter and any final utility plugin so integrated loudness, true peak, and overs represent the actual master output.
Check the loudest chorus, dense transitions, and fades where release behavior can create unexpected movement.
Avoid adding gain, normalization, or format conversion after the meter unless you plan to re-check the result.
Meter Core can sit at the end of the chain as the final quality-control view before rendering.
