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.

Local socket messaging checks which process it is talking to

Under the hood
Useful2 Signal3
Multi-Session

Local socket messages now verify which process is on the other end.

What

The helpers that send messages and control commands over the local socket now carry an expected peer process id, verified against the connecting process along with a child-token check, and the inbox teardown and key-file state move behind an accessor. Failing to publish the inbox auth key still refuses to start an inbox.

Evidence

[uds-messaging] Failed to publish the inbox auth key (refusing to run an inbox no peer can authenticate to):

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