Thanks Keith!

So what is recorded is not necessarily exactly what is sent over Telemetry,
since that spike is not in the recording? Not a problem by itself, I just
want to understand what's the final source of truth - recording I assume.

One might well have come from a baro pressure spike at apogee, so it's
always good to look at the recorded flight log to see what's up.

Any GPS data will always be marked as 'gps altitude' or 'gps height';
everything else is barometric because we can get a lot more data from
that, and small changes are more precise.
