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.

Fast-mode availability records how it was derived

Under the hood
Useful2 Signal0
Models

When fast mode looks unavailable, the cache now records whether that was a guess or confirmed.

What

The cached fast-mode availability record notes when a disabled state was guessed locally rather than confirmed by the server.

Details
  • the disabled branch now carries source: "guess" alongside the existing reason: "unknown"
Evidence

{ status: "disabled", reason: "unknown", source: "guess" }

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