SHA-256 · Daily Merkle Root · Tamper-Evident

Cryptographic Attestations

Every day Goblin House computes a SHA-256 Merkle root over every row in the sources table. The published root and the per-source receipts together make the corpus tamper-evident — anyone can rebuild the root and verify the platform has not silently rewritten history.

Why this exists

The chain-of-custody system hashes every source row at capture time (/source/<id>/receipt). The daily Merkle root extends that to corpus-level integrity: not just "this one source was X" but "the entire archive on date D contained exactly these documents."

If a court order, takedown demand, or internal mistake later alters a source row, every attestation that covered it stops verifying. The reader knows.
