Receipt Chain Visualizer

Public proof surface — verifier global chain, oldest first.

What this proves / does not prove

Full-chain link continuity. Each receipt's prev_receipt_hash equals the immediately-prior receipt's receipt_hash, all the way back to GENESIS. A break is visually obvious.

Per-receipt integrity (recomputing the canonical-JSON SHA-256 from the receipt's canonical fields). That requires the canonical fields, which are auth-gated. See the iOS app's Session History → RECEIPTS view (SH.1).

Source: GET /chain/public — sanitized projection (index, receipt_hash, prev_receipt_hash, server_epoch). Pub keys, nonces, signatures, and JWTs are deliberately stripped from this surface.
