If you remove the 'proport' element and use the 'mensur' element to encode the change in your second example, then Verovio seems to render it as expected.
<section>
<staff n="1">
<layer n="1">
<mensur num="3" sign="C" slash="1" />
<note pname="a" oct="4" dur="1" dots="1" />
<note pname="a" oct="4" dur="2" />
<note pname="g" oct="4" dur="1" />
<note pname="a" oct="4" dur="breve" />
<note pname="a" oct="4" dur="1" />
<barLine form="end"/>
</layer>
</staff>
<staff n="4">
<layer n="1">
<mensur sign="C" slash="1" num="3" />
<note pname="d" oct="3" dur="1" dots="1" />
<note pname="c" oct="3" dur="2" accid="s" />
<note pname="b" oct="2" dur="1" accid="f" />
<note pname="a" oct="2" dur="breve" />
<note pname="d" oct="3" dur="1" />
<barLine form="end"/>
</layer>
</staff>
</section>
The mensural example on the Verovio page has some handy patterns to follow.
https://www.verovio.org/test-suite.xhtml?cat=mensural
There were also a few XML errors in your examples (mostly around duplicate xml:id values). An XML editor can help you spot these problems, since they're probably going to cause other rendering issues if they aren't already.
Cheers!

If I put <mensur> and <proport> elements directly into the <layer>, then it does show, but the proportion number is placed incorrectly (after or overlapping the first note). Example 1 below shows the scoreDef approach, and example 2 shows the layer approach. The first mensuration signature in this example should be “C3” and the second should be “cutC 3”.
