Public Chain Verifier
Recompute every hash. Prove no record was altered.
This tool downloads the full ledger from /api/ledger/export.json, then — entirely in your browser, using SubtleCrypto.SHA-256 — recomputes the entry_hash of every entry and verifies that each prev_hash matches the previous entry's hash. If a single field of any record has been altered, the corresponding row turns red.
Chain compromised.

Legacy entries created before the hash-chain feature have no
entry_hash on file and are reported as such — they are not counted against the chain.
