What

If Claude Code tries to launch its background daemon while npm is replacing the package on disk, spawn now waits for the binary to reappear and retries instead of failing outright.

Details
  • Triggered only when the launcher path is under /node_modules/@anthropic-ai/ and the failure is one of ENOENT, EACCES, ENOEXEC, ETXTBSY or similar.
  • Recorded as tengu_bg_daemon_spawn_reinstall_wait with waited_ms, recovered, respawn_ok and the errno.
  • Spawn now also returns the child's pid and exit promise, and the connect path records connect_errno when it gives up.

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