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
When a tool call is dropped as an unverified refusal but had been approved by the automatic check, the recorded trigger is now classifier_refused rather than unverified_refusal. The recovery path also resolves the dispatch epoch from the message itself before bailing out.
Evidence
classifier_refused
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
