Model audit

How our projections actually performed. For every tracked election the projection is refreshed nightly and then frozen the day before the vote, never edited again. Once the official count publishes we show it beside the frozen numbers and write down what the model got right, what it missed and what changes as a result. No retroactive edits, ever.

The ledger is public at /audits.json and versioned in the open repository, so freezes are independently checkable.
