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.

Half-open cross-session connections are dropped on a deadline

Under the hood
Useful2 Signal2
Elsewhere

Cross-session connections that never send a full line are closed on a deadline.

What

The local socket that carries messages between sessions now closes any connection that fails to send a complete line within a configured first-line deadline, so a stalled or probing peer no longer holds a slot open.

Details
  • Each connection arms a timer on accept, cleared on close or error; the timer does not keep the process alive.
  • The drop is logged, and the first one in a session reports a cross-session inbox auth telemetry value.
Evidence

[uds-messaging] Closing a connection that sent no complete line within

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