Pull-sync now runs on visibilitychange + window focus (in addition to mount
and the slow 15-min safety-net interval), throttled to one call per 5s. The
moment the user returns to the tab the app reconciles, so an Outlook-side
checkbox/star/title change shows up within a second of refocusing the tab
instead of after a 15-minute wait.
To keep this cheap, the Microsoft Graph delta endpoint
(/me/todo/lists/{id}/tasks/delta) is used when we have a stored deltaToken
for a synced list — typically a few hundred bytes per call when nothing
changed. Tokens are persisted on SomedayList.syncDeltaToken (new column,
migration applied) and refreshed each call. On 410 Gone (token expired
>30 days) we fall back to a full fetch and prime a new chain. Delta also
brings remote deletions (@removed) so they propagate locally without
needing a full list scan.
