Not possible.  If there were actual errors, the build would've
stopped.

No, bjam has no such flag.

Possibly.  The way to tell for sure is build in some editor or command
shell window with a long memory or simply redirect the build output
into a file so you can review it later.  If you don't want to wait for
the build to actually occur you could run bjam with the -n flag; that
will do all the computation necessary including warning you of missing
dependencies, but will only print the commands that would be used for
building, rather than executing them.

For now, I think the only documentation is what the build system tells
you about.

Understood.
