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.

Watching an artifact can register a wake-up instead of streaming

Not switched on
Useful2 Signal4
Artifacts

Watching an artifact can register a wake trigger instead of a live stream, and says which you got.

Durable wake watches with trigger and status fields are new here and sit behind off-by-default artifact gating.

What

A watch on an artifact can return on a "durable wake" path: rather than holding a live subscription and receiving streamed updates, the session registers a trigger and is woken with a new turn the next time that artifact is published. The tool result explains which of the two you got. The watch data gained rail, trigger_id, durable_since, status and note fields. None of this exists in v2.1.226.

Evidence

outcome: "durable_wake_registered",

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