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.

CCR v2 Worker Registration

What

A new CCR v2 worker registration flow enables Claude Code to register workers with session servers via a /worker/register endpoint.

Details
  • Workers register and receive a worker_epoch from the server
  • Epoch mismatch (409) handling is now callback-based instead of hard process.exit(1)
  • Enables reconnection flows and transport handoff in CCR v2 sessions
  • Worker registration is also available for standalone session creation (not just environment-based)
Evidence

Worker registration function (search for "/worker/register") and epoch handling (search for "epoch superseded")

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