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.

Remote Control disconnects say why

You'll notice
Useful3 Signal2
Remote Control

Remote Control disconnects now explain the cause, like another device taking over or the session being archived.

What

Code 4090 disconnects now carry a distinct reason each: a newer worker took over, the session is not active, the session was not found, or the client's view of the session is out of date. Each has plain-language text, for example that a session was ended or archived from another device or app.

Details
  • The epoch-mismatch handler emits a session-not-active event alongside the existing stale and mismatch events, each now carrying a reason.
  • The diagnostic line was reformatted to worker epoch mismatch (409) reason=....
Evidence

this session was ended or archived from another device or app (code 4090)

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