We don't claim authority. We prove verifiability.

Every day we take a full snapshot of a small set of public, official datasets and record exactly what changed — including records the publisher quietly removed. Each row carries its source URL, retrieval timestamp, and a SHA-256 hash so you can check it yourself.

What this is: a read-only archive of dated facts, not a news site, not an analysis product, and not a rating service. We publish manifests (including gaps) so coverage is auditable. Authoritative status belongs to the original agencies; we only make the as-of record reproducible.

Datasets

Why a dated archive matters

Public data sources are updated without notice. A record you cited last month may be amended or removed today, and the publisher usually offers no history. Once a day passes, that day's exact state cannot be reconstructed by anyone who did not capture it. Our archive starts accumulating that history on day one.

What you can verify

Manifest per source per day — record count, four change counts, dataset hash, and explicit gap disclosure.
Sample citations — copyable, with source_url, sha256, first_seen / last_seen, and change_ref.
Original bytes — each day's full source payload is archived separately from the normalized change events.
