…istory When listNewMessageIds hits the 3-page cap with more pages pending, the poller froze history_cursor but restarted pagination at page 1 on every subsequent poll. Once pages 1-3 were fully deduped the cursor could never advance and mail on page 4+ was permanently lost. Persist the dangling nextPageToken in sidecar_state (migration 32) and resume from it on the next poll. Clear the token when the listing completes or on history-gap re-anchor.

When
listNewMessageIdshitsMAX_HISTORY_PAGES=3with a danglingnextPageToken, the poller correctly freezeshistory_cursorbut restarts at page 1 on every subsequent poll. Once pages 1–3 are fully deduped, the cursor can never advance and mail on page 4+ is permanently lost — silent data loss during Gmail history bursts for sidecar mailboxes.Test plan
