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.
Server-only remote events cover queued notifications too
Under the hood
Useful2Signal3
Remote Control
The remote event lanes now accept queued notifications as well as workflow launches.
What's wrong with this entry?
Anonymous. No account, no email.
What
The SSE and stdin lanes now accept both workflow_launch and queued_notification as server-only payload types instead of just the first, and the events reporting a dropped payload were renamed to include the type that was rejected.
Evidence
cli_stdin_server_only_type_dropped
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
