0126 — The poll loop waits one interval before its first claim

Context. time.NewTicker(PollRate) delivers its first tick only after one full interval, so a consumer entering the poll loop idles PollRate before its first read.

Decision. Accept the delay: enter the loop and wait for the first tick, matching the pattern of the parked V1 Poll. No immediate claim before the loop.

Consequences. First-claim latency equals PollRate — acceptable for lab use. If first-claim latency ever matters, the fix is a single immediate claim before entering the loop.
