Question

As near as I can tell, ^ does not anchor beginning of line in the pattern argument for %INCLUDE%

Am I misunderstanding?

No, you are not misunderstanding. To be honest, I couldn't figure out the solution from the documentation at TWiki.IncludeTopicsAndWebPages nor from a glance at the code, I've been using the experimental approach.

The analytical part: The pattern operand in %INCLUDE{... pattern="..."}% is applied not per line, but to the topic as a whole, so the caret ^ matches only at the beginning of the whole topic. But this is only why the simple approach doesn't work, and no solution. In the case that you want to use the caret to match "a line containing 'foo' from its beginning to its end" look at Sandbox/CaretInRegexWithINCLUDE, where I demonstrate how to achieve that: Instead of ^.*foo, write [^\r\n]*foo, so the complete regex would read ^.*?([^\r\n]*foo.[^\r\n]*).*
