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Worker registration function (search for "/worker/register") and epoch handling (search for "epoch superseded")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