"""trace_entry.py.

GuardTraceEntry is a dataclass which doesn't explicitly define the
schema of our logs, but serves as a nice, easy-to-use dataclass for when
we want to manipulate things programmatically.  If performance and
filtering is a concern, it's probably worth writing the SQL directly
instead of filtering these in a for-loop.
