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.

Settingsnot in their notes

switchModelsOnFlag
What
The switchModelsOnFlag setting, which automatically switches models when a response is flagged as a refusal, now reports its own telemetry event when you change it. It only appears when a gating check passes.
Details
The gating helper was renamed in this build; several unrelated functions share its minified name, so what it actually checks is not resolved here.

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