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.
When Claude Code detaches from a remote (CCR) session by resuming it locally (fork via bridge), it now shows an informational notice:
> This terminal now has its own copy of the session: new work here stays local and will not appear in the Claude app. To continue on your phone later, run /remote-control in this session.
Evidence
Bridge fork message (search for "This terminal now has its own copy of the session")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
