CLAUDE_CODE_POLL_EVENTS alone can once again switch on poll-event delivery
What
The function that decides whether Claude Code uses poll-based event delivery previously required two additional internal conditions to be true on top of the CLAUDE_CODE_POLL_EVENTS environment variable. Those extra conditions have been removed, so the function now only checks CLAUDE_CODE_POLL_EVENTS.
Why
This reverses a prior change that had required the SDK or streaming-input entry path to separately confirm that event ingress was wired before the environment variable would take effect. Now, setting CLAUDE_CODE_POLL_EVENTS is sufficient on its own again.
