2310 - add some more tracing

I've been growing lax on white-box testing when it's one of the three
big thrusts of this whole effort. Perhaps it was because I got too
obsessed with keeping traces stable and didn't notice that stable
doesn't mean "not changing". Or perhaps it's because I still don't have
a zoomable trace browser that can parse traces from disk. Or perhaps
$trace-browser is too clunky and discourages me from using it.
Regardless, I need to make the trace useable again before I work much
more on the next few rewriting transforms.
