DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Dialog view events are recorded once per showing rather than on every redraw.

What
A new hook runs an effect at most once each time a dialog is revealed, keyed by its identifier and optionally by the reveal count. The auto-mode default nudge uses it, so its impression event with the current mode is now recorded once per showing rather than on every render.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
