Source Intelligence

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.

Durable wake subscriptions no longer behind a flag

You'll notice
Useful3 Signal4
Sessions

Sessions that can be woken up later no longer depend on a flag; that mechanism is always on.

What

The two flags that could switch off durable wake subscriptions, the mechanism that lets a session be woken later, are removed and no longer read anywhere; the feature is now always on. The failure message that blamed the flag is gone, and the "already holding" note now mentions restored subscriptions.

Details
  • Both flags fell back to on, so behaviour is unchanged for anyone who was not opted out server-side.
  • A reducer that batched stale-guard seeds was removed with them.
Evidence

Durable wake subscriptions were switched off for this session before the registration ran; retrying will not help while they stay off.

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