THE EVIDENCE LEDGER

A permanent audit trail for every company claim.

A database tells you what is true now. The CompanyProof ledger also remembers what your system said, why it was allowed to say it and when the supporting source changed.

WHAT THE LEDGER STORES

More than a log. A claim-level chain of evidence.

Every record is designed to answer the questions a compliance reviewer, auditor or downstream system will ask later.

Claim identityclm_01J62E8A

Stable across verification, policy decisions and future events.

Published valuecompany_status = Active

The exact value accepted by the publishing system.

Observed valuecompany_status = Active

The official value returned at verification time.

Source record and retrieval time stay attached.

Decision historyverified → ledgered

Every verdict, correction and delivery becomes an event.

Monitoring stateactive · webhook armed

The claim remains connected to registry changes.

THE PROOF LIFECYCLE

Correct when published. Stale when the source changes.

The ledger preserves both facts. It never rewrites history and pretends the original answer was wrong when it was supported at the time.

WATCHING

WHY A LEDGER, NOT API LOGS

Technical traces explain a request. Evidence records explain a decision.

STANDARD API LOG

Records the request and response
Optimised for debugging
Usually deleted after a short retention period
Does not know what was published
Does not watch the underlying fact

COMPANYPROOF LEDGER

Records each material company claim
Optimised for audit and decision evidence
Preserves source lineage and timestamps
Connects published and corrected values
Monitors the source and reports staleness

SIGNED CHANGE WEBHOOKS

The ledger becomes operational when the truth changes.

A stale event includes the affected claim, the value your system published, the current source value and both timestamps. Your application can update, block, review or notify automatically.
