The costs page states both deductions and, for each game, the maths return alongside what players actually receive. It is rendered from /api/fees, which the server generates from the same schedule it charges, so the published terms cannot drift from the behaviour. Backups every five minutes with a rolling 24 hours. Each dump is checked for size and format before replacing the previous one — a backup script that reports success on a truncated file is worse than none, because it turns a recoverable outage into silent loss found only when needed. A nightly job restores the newest snapshot and asserts the ledger balances. The standby continuously restores into a shadow database and swaps only after verifying the books, so it is never mid-restore when needed and never promotes a corrupt copy. Promotion does not contact the dead machine, and it refuses to start if the ledger does not balance. Kernel tuning is tied to measured limits, not copied defaults. Alby Hub is explicitly excluded from snapshot restore: publishing a stale channel state can lose the channel balance outright. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
