TidelineLedger hashes
Every day after the daily candle is read, Tideline takes a SHA-256 of the whole flip ledger, stores it here and posts it to the community group. Because the ledger is append-only, each day's hash should be reproducible later from the rows that existed that day; an edited or deleted row would contradict a hash already in other people's hands.
Check it yourself
Download export.csv, drop the header line and hash the rest. The response header X-Ledger-SHA256 carries the same value.
