Evidence & audit trail
Evidence an inspector can trust, because no one can quietly edit it
Evidence uploaded to CLEX Legal is immutable, content-addressed and versioned, and is opened only through short-lived signed links. Every change is written to an append-only audit log in which each entry is chained to the one before it, so any tampering is detectable by verifying the chain.
What it does
How evidence & audit trail works
- 1
Immutable, versioned evidence
A document is stored once, identified by its content, and never overwritten. A correction is a new version; the old one stays.
- 2
Short-lived, signed links
Files are never exposed at a public address. Each download uses a link that is signed and expires.
- 3
A hash-chained audit trail
Who did what, when, to which record and what changed — written in the same step as the change itself, and chained to the entry before it. One button verifies the chain.
- 4
Reports you can hand over
Run the audit trail for any record type, change kind, person and date range, and download it for the auditor.

Questions
About evidence & audit trail
What is a tamper-evident audit trail?
It is a log written so that altering or deleting an entry can be detected afterwards. In CLEX Legal each entry carries a hash that includes the previous entry's hash, so changing any past entry breaks every link after it.
Can evidence be deleted?
Evidence is not edited or overwritten. A record can be made inactive, which is itself recorded, but the evidence and the history behind it remain.
