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.

Session rename after device binding is signed

Under the hood
Useful1 Signal2
Cloud Sessions

The automatic session rename after device binding is now signed.

What

The automatic session rename that follows session creation now attaches an event signer derived from the device binding, and only when the binding succeeded.

Evidence

tengu_device_bind_title_latched

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