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.

What
Shutdown now starts a settle step for first-party event logging before the other shutdown work, races the three shutdowns against a 500 ms timer, then awaits the settle step, so in-flight events get a chance to flush past that timeout.

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