Turbo’s documentation isn’t incomplete, it’s unconnected: Drive, Frames and Streams sit side by side with nothing saying what links them or how to choose. This is the reference I wanted when I started, written by reading the source of Turbo 8.0.23 and turbo-rails 2.0.23 rather than the docs, because that is where the gaps are.

Among the things it documents that the official docs don’t: turbo:before-cache stops firing the moment you enable morphing, which silently disables the teardown pattern every Rails app has been using since Turbolinks. Action Cable never replays broadcasts missed during a network drop, with no error and no event. idiomorph’s pantry uses moveBefore where available and insertBefore otherwise, which is why some morphing bugs reproduce in Safari and are invisible in Chrome.

Eight diagrams, and a symptom index at the end for when you arrive with a bug already on your hands.
