Sync state (7) + pending items

Sync status is more than one dot — this page covers the full seven states, the pending-items list, and how to handle sync errors.

Bookshelf cards (zh-TW shown): green ✓ at the top-right of each book = synced; the indicator changes color when pending

Seven sync states

State	Meaning
✅ Synced	Local matches cloud, nothing pending
🟡 Pending sync	Changes not yet pushed (pending)
🟡 Syncing	Currently pushing
❌ Sync error	Push failed (rate limit, server issue, etc.)
🔒 Sign-in needed	Session expired — re-sign-in to keep syncing
✈️ Local mode	Manually offline, or no network detected
⚠️ Conflict	The same file was edited on multiple devices — needs resolving

If changes haven't synced yet, expand to see which:

Pending sync: 3 items
- Chapter 8 (minor edit)
- wang-xiaoming.md (new paragraph added)
- writing-spec.md (one rule changed)

Knowing which items are unsynced lets you decide whether to wait before switching devices.

Next to the indicator, the last sync time is shown:

"Just synced" / "3 minutes ago" — normal
"Over an hour ago" — a warning sign; something pending may have failed to push, consider a manual sync

Don't want to wait for background sync:

Click "Sync error" to expand the reason:

Error	What to do
Rate limit (too many requests)	Wait a minute or two — it auto-retries
Server error	Wait a few minutes — Slima auto-retries
Session expired	A re-sign-in flow appears; syncing resumes after sign-in
Conflict	Go to the conflict resolution flow
