The prose lane branched before the CIDER buffers landed, so the page still described C-c C-b as the minibuffer prompt. It is the conditions buffer now, the prompt moved to C-c C-M-b, and C-c C-i, C-c C-a and C-c C-g are missing entirely. Checked against the real keymap rather than against the source: loading flan-mode in a batch Emacs and asking key-binding what each one resolves to. That is what caught C-c C-g being unbound - flan-dape.el registers it from its own file so that flan-mode still works without dape installed - so the row says so rather than claiming a binding that is not there.
