Under the hood
No documentation found
CCR worker requests can now target a custom session URL instead of the default endpoint
What
The function that sends CCR worker requests to a Claude session now checks for a ccrSessionUrl() value from the host's launch options first. If one is set (with any trailing slashes removed), it's used as the base address for the /worker/... call; otherwise Claude Code falls back to the default .../v1/code/sessions/{id} URL. When a socket is used for the connection, the log now also notes "over ${socket path}" for extra context.
Why
This allows worker requests to be redirected to a non-default session endpoint, useful when a session isn't reachable at the standard URL.

Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what CCR stands for or in what situation a custom ccrSessionUrl would be set.
