Proof — the hash-chained record

seq #138
row_hash b36994d6acac9f5fe0637ef49358a54b93023978f13343c02a4ef8437c7e5d70
prev_hash 8d64fa2e161990b5a94d9d1a45efdf89a4b4cecda46be87bfa0c14da0ffc421c

This exact row, with its canonical preimage, is public at /api/ledger/export. Recompute its hash with the standalone verifier — it shares no code with this site. The chain head is timestamped into Bitcoin.

Evidence or it doesn't ship.
