RegBench

Audit-of-record ledger

Each carrier has its own hash chain. Every assessment, review and exam pack appends an entry whose hash covers the previous entry, so an altered or deleted record breaks every later link. The database itself refuses updates and deletes on this table.

Chain verified. 702 entries recomputed; every link holds.
Tamper simulation. A copy of the chain with entry #1164 altered fails verification at entry #1164 (entry hash mismatch (entry altered)). The real table was not touched: the database aborts any UPDATE or DELETE on it.

How an examiner verifies independently

  1. Export the carrier's ledger (seq, ts, kind, ref_id, payload_hash, prev_hash, hash).
  2. Confirm the first entry's prev_hash is sixty-four zeros.
  3. For each entry, recompute SHA-256 of 'prev_hash|ts|kind|ref_id|payload_hash' and compare with hash; confirm prev_hash equals the previous entry's hash.
  4. For any case file, canonicalise its assessment JSON (sorted keys, no whitespace), hash it with SHA-256 and compare with the ledger's payload_hash for that assessment.
  5. Compare the pack's head hash with the hash published in the carrier's periodic anchor statement.
