The poll loop only updates cursorByHandle after passing if (!msg || !msg.id || !msg.message) continue;, so media-only posts (or other messages without message text) never advance the cursor. On channels that emit many non-text posts, each interval re-reads the same IDs, increasing API load/rate-limit risk and potentially preventing progression to newer text posts when the fetch limit window is saturated.

The interval starts a new pollTelegramOnce() on a fixed schedule without checking whether the previous poll is still running. Since each poll performs network calls per channel and an intentional per-channel delay, slower runs can overlap, causing concurrent reads/writes to shared cursor state and duplicate upstream requests that make Telegram throttling more likely.
