# 99½ REBORN — Rollback Plan

Rollback is static-file replacement only.

## Immediate rollback

1. Re-upload the previous full website ZIP contents.
2. Confirm `/play/release.json` shows the previous runtime.
3. Ask testers to close old tabs and reopen `/play/`.
4. Keep `/repair/` reachable.

## What rollback does not do

- It does not delete player localStorage.
- It does not delete Cache Storage.
- It does not upload or restore cloud saves.
- It does not fix old tabs that are still open in memory.

## When to ask players to export first

Ask players to export their current session before rollback if they are in a protected/session-only tab, if graphics recovery is shown, or if they have recent Drive Memories they care about.
