Offline sync

The Scorer Tool keeps working when the network drops — a status bar fixed at the top always shows where things stand:

• “All sent” — everything has reached the server.
• “Offline · N changes waiting” — changes are piling up.
• “Sending N changes…” — currently transmitting.
• “N changes not sent · Last try Xs ago” — with a manual “Send now” button.
• “N match(es) need a decision” or “The server refused a change” (red, tappable) — this needs your input.

When there’s a conflict

If someone else edited the same match in the meantime, tapping the red bar opens “Unsent changes”: set by set, you see “On the server” next to “On this device”, with the differing sets highlighted. You decide deliberately:

• “Keep mine” — overwrites what was counted at the server.
• “Take theirs” — discards what this device counted.

If the server refused a change, the reason is shown in plain text, with “Discard it”.

Note

Not everything is buffered — loading the match list and check-in run without a buffer, because their own UI already reverts honestly on failure. Reloading the page mid-offline isn’t safe yet (no service worker) — deliberately left for later.
