Real interface captures from the platform and its public evidence surfaces.

News Ledger interface with source coverage, revision counts, and searchable article records. — The public ledger exposes source-provided metadata, capture provenance, and revision history while full evidence payloads stay private.

Preserving observations, not just pages

News Ledger records what approved publisher feeds exposed, when each response was observed, and which fields changed. Captures and article versions carry SHA-256 fingerprints, while predecessor links keep the revision chain inspectable.

An append-only evidence model

SQLite triggers reject updates and deletes to feed captures, article versions, classifications, and reception snapshots. The collector creates a new version only when the normalized article fingerprint changes.

A deliberate public boundary

Public views expose source-provided metadata, short excerpts, revision counts, and provenance. Full feed payloads and body text remain private evidence, and classifications retain their publisher, machine, or human origin.
