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.

Background-session rendezvous server rebuilt as an object

Under the hood
Useful2 Signal2
Sessions

The socket background sessions connect through is now created per start rather than shared.

What

The socket that background sessions connect through, including its authentication handshake, 30-second heartbeat, attacher caps, startup watchdog and prompt-draft restore, moved from module-level state into an object created per start, and its job-state reads and writes now take a storage backend. Behaviour, including the accounting of unauthenticated drops, is unchanged.

Evidence

[bg-rv] dropped

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