What

A worker that starts before its session authentication headers are available now re-reads them on a fixed delay schedule rather than failing outright, so a slow handoff no longer kills the worker.

Details
  • Each attempt logs [remote-io] no auth headers, re-reading in ${...}ms.
  • Success reports cli_worker_lifecycle_init_auth_retried at info level; running out of attempts reports cli_worker_lifecycle_init_auth_retry_exhausted at error level with the attempt count and diagnostics. Both event names are new in this build.
Evidence

cli_worker_lifecycle_init_auth_retry_exhausted, cli_worker_lifecycle_init_auth_retried, [remote-io] no auth headers, re-reading in

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