- reject a second project path as a usage error instead of analysing only the first - resolve the default recall manifest from the working directory, else from the pipe checkout the binary was built from, so recall works outside the repo - write --write-baseline even when guide --yams fails to persist - drain the yams child's stdout so a chatty yams cannot block pipe - report any unexpected exception in one line with exit 2; PIPE_DEBUG=1 prints the stack trace
